Neil 4efc86a33c feat(app): open Markdown files from the OS in the floating workspace (#17906)
* feat(app): open Markdown files from the OS in the floating workspace

Registers Orca as a Markdown handler on macOS, Windows and Linux, and opens
an OS-handed .md/.markdown/.mdx file as a floating-workspace editor tab —
the one editor surface that needs no project. Works cold-start and when
Orca is already running.

Main buffers the paths and both pushes to a live renderer and answers a
pull on renderer mount, mirroring SkillShareDeepLinkState. The buffer is
only released once delivery is possible: the renderer's pull is what proves
its ui:openMarkdownFiles listener is attached, because a push into a window
whose renderer has not subscribed is dropped by Electron with no error. Both
the push and the pull restore an undelivered batch, and a renderer reload
clears the latch so the fresh renderer re-proves itself. Paths are stat'd and
proven to be files before authorizeExternalPath sees them.

Windows association is registered by hand in the NSIS include rather than
through electron-builder's `fileAssociations`: app-builder-lib emits
APP_ASSOCIATE, whose first line overwrites Software\Classes\.md's default
value with no backup — silently taking .md from whichever editor owns it,
for every existing user on their next update — and APP_UNASSOCIATE never
restores it. The hand-rolled registration is additive (ProgID +
OpenWithProgids + SupportedTypes) and leaves the user's default alone;
verified end to end on a real Windows 11 host.

Closes #10138

* fix(os-open): register the new listener in the IPC inventory, and guard a non-array payload

CI caught two things the local run did not.

useIpcEvents-lifecycle.test.ts is an inventory of every App-lifetime IPC
listener and the exact order they register in; ui.onOpenMarkdownFiles now
appears there, positioned after the workspace-shortcut bridge's last
listener, which is where it actually registers.

Chasing that failure surfaced a real gap: the pending-open payload crosses
the preload boundary, so a stale or mismatched preload can resolve with
something that is not an array, and reading .length off it threw inside the
promise chain instead of failing at the boundary. Array.isArray now gates it,
with a regression test.

Neil 28373fcea7 fix(windows): repair the install-dir package ACL that blanks the window (#17740)
* fix(windows): repair the install-dir package ACL that blanks the window

An install tree carrying an orphan AppContainer ACE (S-1-15-2-<x>) with no
ALL RESTRICTED APPLICATION PACKAGES grant denies Chromium's LPAC children read
on the shipped modules; they die at init with 0x80000003 and the window stays
blank forever (electron/electron#51761).

- Tighten the probe verdict to require the S-1-15-2-2 grant specifically: an
  ALL APPLICATION PACKAGES (S-1-15-2-1) ACE, the Program Files default, does
  not appear in an LPAC token and cannot satisfy the orphan.
- Drop BUILTIN from the English-locale heuristic (fr-FR/es-ES print it
  verbatim) so a localized icacls is correctly reported as un-name-checkable.
- Add an additive, marker-guarded icacls self-repair: an inheritable root
  grant plus a flagless (RX) /T pass, never /grant:r.
- Route the crash-loop dialog through a testable prompt module that names the
  permission cause, offers Copy Commands without dismissing itself, and keeps
  the graphics-driver hint.

The repair only runs on win32, off serve mode, and only on the exact probe
verdict that reproduced the crash.

* docs(windows): correct the install-tree ACL walk cost model

* fix(windows): keep the install-ACL poison gate at the reproduced shape

An orphan package ACE alongside the Program Files ALL APPLICATION
PACKAGES default launches clean on win32 10.0.26200 / Electron 43.4.1,
so requiring S-1-15-2-2 specifically declared poison on healthy installs
- and this branch acts on that verdict with a tree-wide icacls write and
the crash-recovery dialog's primary cause. hasRestrictedPackageGrant
stays reported for triage; only the verdict reverts.

Neil 4ac8a8912c fix(startup): install the app environment with the userData decision (#17755)
src/main/index.ts decided where userData lives at module scope, then installed the
AppEnvironment port ~180 lines later inside the single-instance-lock block. Every
statement in that gap was a latent failure: a path resolve there either threw
'AppEnvironment not initialized' and killed the process, or — with the accessor
installed but the decision not yet run — would have memoized the pre-override
directory in getCanonicalUserDataPath() for the whole session.

The first outcome shipped. #16761/#16698/#17509 were one statement landing in that
gap and killing every macOS `orca serve` across 1.4.190-1.4.192; #16762 moved that
call but left the gap.

Install the port and capture the canonical path immediately after the two calls
that decide them, so the window is zero rather than small. Both are inert at this
point — ElectronAppEnvironment holds no state and calls `app` lazily per accessor,
and initDataPath only joins strings — so nothing that depended on the old position
moves with them. The secret store stays where its pre-ready Keychain note applies.

The throw is kept and still covers the case it should: resolving a path before the
decision has run.

Guarded by a source-level assertion that the decision, the install and the capture
stay adjacent.

Jinwoo Hong 8f15f217a2 Preserve user-set workspace names across branch changes (#17448)
* fix(worktrees): preserve user workspace names across branch changes

* test(worktrees): cover pinned rename metadata

* fix(workspaces): address display-name review edge cases

* fix(workspaces): keep automatic names fresh across refreshes

* fix(workspaces): preserve legacy CLI labels

* fix(workspaces): preserve display-name provenance across hosts

* fix(workspaces): honor legacy display-name provenance

* fix(workspaces): fence display-name refresh races

* fix(workspaces): accept peer renames from provenance-less hosts

The old-host preserve fence kept a pinned local label on every refresh,
which also suppressed a legitimate rename another client persisted
through the same host until app restart. Narrow it to labels the host
re-derived itself (branch short name, or path basename when detached);
any other changed label in a mode-less response is explicit meta a peer
wrote there. Stale prior-label responses stay covered by the downstream
staleness fence, in-flight writes by the pending fence.

* refactor(workspaces): unify display-name pin derivation

Three call sites (renderer optimistic update, local IPC updateMeta
handler, remote worktree.set handler) each restated the same formula;
a future edit to one would silently skew provenance between paths.

Neil 20a12a6a46 perf(codex): share one launch-prep hook install across a spawn burst (#17669)
* perf(codex): share one launch-prep hook install across a spawn burst

Codex launch prep runs a full managed-hook install on every local PTY
spawn, and both install lanes serialize globally per Codex home. Opening
a multi-pane worktree therefore paid N full installs back to back, and a
resumed Codex pane prepares twice. Concurrent spawns for the same runtime
home now share one run; the promise is dropped as soon as it settles, so
the next launch still re-reads hooks.json and the user's trust state.

Also split the `host_env` spawn-timing phase, which spanned the entire
Codex preamble and pinned that cost on the env builder that ran last.

* refactor(codex): unify the two hook-install single-flight lanes

Both the WSL and launch-prep lanes now share one generic in-flight helper
instead of duplicating the map bookkeeping. Also routes the WSL launch-prep
install through the serialized variant, which closes the same per-spawn
serialization gap on WSL that the native lane just got.

* refactor: extract the shared in-flight run dedupe

The codex hook service and the GitHub conflict-summary cache had grown
near-identical private copies of the same single-flight helper. Both now
use one module, which also keeps the hook service clear of the 300-line
budget. The shared copy keeps the identity check on clear so a late settle
cannot evict a newer entry for the same key.

spellbook 18e8fe4770 fix(serve): install supervisor disconnect quit after app environment init (#16762)
Moves installServeSupervisorDisconnectQuit(isServeMode) out of module scope in
src/main/index.ts to just after setAppEnvironment() and initDataPath().

The call resolves the serve update handoff path through getCanonicalUserDataPath(),
which throws by design until the app environment accessor is installed. At module
scope that throw was unconditional on macOS whenever the CLI set
ORCA_SERVE_UPDATE_HANDOFF_PATH — which it does by default — so every `orca serve`
process died at startup before it could listen, and the supervising service manager
restarted it into the same crash. Reported in #16761, #16698 and #17509; shipped in
1.4.190 through 1.4.192.

Guards added so it cannot drift back: a source-level ordering assertion that also
pins the call synchronous and inside the single-instance block, and a runtime test
that keeps the real path resolver, since the existing suite mocks it and therefore
could never have caught this.

* fix(codex): accept durable WSL scan state

* test(codex): cover the drain's inode-identity guard against destination replacement

Removing the four `target_auth -ef temporary_destination_auth` assertions left
all 33 apply-script tests passing, so a regression deleting them would have
shipped silently. Reproduced before writing this.

A hash check cannot catch the case. The pinned hard link keeps the original
inode, so it still hashes correctly after another writer atomically renames a
different file over the destination path; only inode identity sees it. Without
the guard the script exits 0 and retires the source, leaving the user holding
bytes nothing validated. The new case asserts the source survives.

The harness is split by responsibility so no file exceeds its max-lines budget:
fixtures, the coreutils interference shims, the run types, the apply runner, and
the recovery/absent runners. The atomic-rename hook is deliberately separate
from the in-place rewrite shim because different guards catch them.

* fix(codex): keep the split drain harness inside the child-process boundaries

Extracting the harness into non-test modules moved it out of the exemptions the
single test file had: three new files import child_process, and two spawned
without windowsHide.

Adds the three to the import allowlist, and sets windowsHide on the spawns
rather than exempting them - the flag is correct for these calls regardless of
the ratchet, and they are skipped on win32 anyway.

Brennan BensonandMerge Sim e54cfc1901 fix(omp): read Pi/OMP static state-title markers and retire stale spinners (#14602)
* fix(omp): read Pi/OMP static state-title markers and retire stale spinners

OMP 17.2.12 replaced its animated braille title frames with static markers
on WSL/ConPTY (`π : working`, `π > idle`, `π ! needs input`). Orca read all
three as idle, so a working OMP pane lost its status, and a synthetic title
spinner started by an earlier hook kept rotating after its status row was
gone.

Classify the markers from one shared table so a later upstream punctuation
change is a row, not a reparse, and stop the spinner when the hook row it
stands in for is cleared or dismissed.

Brennan BensonandJinwoo-H d9870c6c75 fix(browser): apply the app-wide HTTP proxy to embedded browser sessions (#15536)
* fix(browser): apply the app-wide HTTP proxy to embedded browser sessions

The proxy setting was only ever written to `session.defaultSession`, but browser
guests run on their own `persist:orca-*` partitions. Any host reachable only via
the configured proxy failed to load in an embedded tab, landing on
`chrome-error://chromewebdata/`, while the same setting worked everywhere else.

Adds a per-session applier alongside the existing defaultSession path, keyed by a
WeakMap so one session's applied config can't suppress another's, and applies it
to every browser partition through the single installer they all pass through.
Startup awaits an explicit sweep so the first guest navigation can't race the
installer's fire-and-forget write, and a settings change re-sweeps so toggling
the proxy takes effect without a restart.

Env-var fallback and the system-proxy probe mirror the defaultSession behaviour,
so a browser partition resolves the proxy the same way the rest of the app does.

Brennan Benson fd9125ea8c feat(native-chat): Codex structured native chat restructure (#16729)
* feat(native-chat): port structured Codex sessions from restructure-recovery

Rebuilds the desktop structured native-chat implementation from
brennanb2025/native-chat-restructure-recovery (tip 4e31c08db3) on top of
current main as a single commit, scoped to the local Codex path.

Ported:
- Structured agent-session core: durable record store + single-writer lease,
  canonical journal, agent-session wire host/attach/eviction/subscribers,
  `agentSession.*` RPC surface (registered via ALL_RPC_METHODS; host-side
  mobile allowlist included for wire compat), pty write gate, transcript
  additions, and the Codex app-server adapter/launch resolution.
- Renderer: NativeChatStructuredSession view/composer stack, structured
  launch path with the single-flight guard, local structured session tabs
  sync, activation gate + structured inventory (read-only
  `agentSession.handoffStatus` probe), agent-session tabs in the tab strip,
  AI-vault structured session activation, and the settings pane with the
  parent Experimental Chat UI toggle plus the nested "Use updated structured
  native chat" toggle. New sessions require both flags, agent codex, no
  prompt, and a local non-WSL, non-Windows-host execution host
  (structured-native-chat-availability).
- Fixes 72c013cea6 (verified Codex launch recovery), 8ddbaf5e3d (defer
  native terminal view switching affordances), and 4e31c08db3 (release the
  launch gate after a visibility retry) with their regression tests,
  including the third-launch-after-retry guard case.
- Cross-version agent-session wire test + CI lane, packaging entries
  (proper-lockfile, agent-tooling asar excludes), and the wire-compat doc
  section.

Deliberately not ported: mobile/ changes, the Claude structured runtime
(only the claude-transcript-branch-proof and claude-structured-owner-identity
leaf modules remain, backing the kept TUI-recovery arms), the terminal↔chat
adoption/handoff flow (`agentSession.adoptTerminal`/`requestHandoff`, the
handoff request engine, TUI adoption machinery, orca-runtime adoption
methods), renderer switching affordances and their dead leftovers, the
hook/subagent-status refactor cluster, and unrelated branch changes. The
crash-during-acquisition recovery path (restart handoff adjudication,
restore/reverse re-acquire, lease schema handoff keys) is kept because every
plain direct launch depends on it; a trimmed handoff coordinator exposes
only status/restore/close.

Branch edits that targeted files main has since split (ipc/pty.ts,
worktrees.ts, rpc/methods/terminal.ts, useIpcEvents, pty-connection,
store/slices/terminals.ts, runtime-types, web preload) were re-applied to
the split modules, preserving main's newer logic (Windows CIM fallback,
browser tab close rework, cold-restore resume flow, dispatcher threading).

Known seam: the mobile clipboard image-provenance CONSUMER gate ships
(agentSession.send refuses unproven mobile image refs with
agent_session_image_untrusted) but the producer hunk in
rpc/methods/clipboard.ts stays with the unported mobile cluster, so mobile
image sends into structured chat fail closed until that side ports.

* fix(native-chat): trust only authenticated local image uploads

* fix(build): preserve Windows process-tree patch application

* test(windows): include process creation time in addon fixture

* fix(build): run windows-process-tree node-gyp from the physical package dir

gyp expands the node-addon-api dependency by probing node, whose cwd
resolves to the package's physical directory in the store, so the emitted
target is a store-relative ../../../../node-addon-api@... hop. gyp then
resolves that hop against the rebuild cwd; from the node_modules
symlink/junction it escapes the store and configure fails with
"node_addon_api.gyp not found" (run 32999886072).

Rebuild from realpath(package dir) so both bases agree, matching how the
package manager itself runs native install scripts. The regression test
replays gyp's expansion+resolution against the planned cwd and fails
without the fix.

* fix(native-chat): keep chat tabs visible through terminal closes and empty-worktree launches

Two proven blockers in the native Codex tab contract:

closeTerminalTab pre-empted the canonical unified close. With one terminal
left it deactivated the worktree on a terminal/editor/browser-only check,
blanking a workspace that still held a renderable agent-session tab; with
two or more it pre-picked a successor from terminal entities only,
re-stamping the group active before closeUnifiedTab's MRU/neighbor repair
could land on the chat tab. Successor choice now defers to the unified
contract whenever the terminal has a unified row, and deactivation is
gated on the unified renderable count (matching leaveWorktreeIfEmpty),
with the legacy pre-pick kept only for terminals without a unified row.

A structured session created on an empty worktree was published into the
host's headless group while preserveLocalLayout froze the local layout,
leaving the tab in store but permanently off screen. A preserveLocalLayout
owner now always takes client-owned placement — repairing a rendered
leaf whose group record is missing, or materializing a rendered group on a
truly empty worktree — and applies the client-derived layout repair while
still rejecting host-authored layout.

Regression tests drive the real store through closeTerminalTab (git
worktree and folder workspace) and the real snapshot applier for the
empty-worktree adoption states; all fail without the fixes.

* fix(native-chat): anchor an unmatched chat echo where it was sent (#16117)

* fix(native-chat): anchor an unmatched chat echo where it was sent

The reported symptom was old user messages replaying below every new turn, so the
conversation read as scrambled. The cause was not that the echo failed to match a
transcript row. Claude consumes a mid-turn send through a `queued_command`
attachment and writes no `type:"user"` record for it, so some echoes can never
match, and no amount of matching will change that. The cause was WHERE an
unmatched echo rendered: buildMobileNativeChatTransientData appended every pending
item after the entire transcript, so it re-read below each turn that landed
afterwards.

Render each echo directly after the transcript row it was sent against, using the
baseline the send already captures. An unmatched echo is then at worst a duplicate
in the right position rather than a scrambled one, and it stays visible. Echoes
sharing an anchor keep send order; a send with no baseline, or one whose anchor
folding dropped, still falls back to the tail.

Deliberately NOT fixed by deleting the echo. Inferring from send ordering that an
echo can never match, then removing it, loses the user's own text for a message
the agent did receive, and it cannot fire in the common case anyway - measured
drain groups are 1,017 of size 1 against 55 larger. It also escalates an existing
gap: the count pass has no baseline-tail guard, unlike the glue pass, while
`messages` is a 40-row window that head-trims, resets on reconnect and grows at
the front on loadEarlier, so a false landing there would license deleting a
DIFFERENT outstanding message.

That count-pass gap is real and left for a separate change; anchoring makes its
worst case a duplicate in place rather than a scrambled conversation.

* fix(native-chat): refuse structured chat on every Windows execution path

canUseStructuredNativeChat only refused win32 when a project runtime
resolved, so folder-workspace keys (and other keys with no project
runtime) failed open into structured chat on Windows. Fail closed on
win32 unconditionally after the host check, matching the settings copy:
local macOS/Linux only; Windows/WSL/SSH stay on terminal chat.

* fix(native-chat): restore runtime refusals behind the win32 gate

506d375de3 replaced the project-runtime checks with a bare platform test,
so a WSL or repair-required runtime resolution would no longer refuse
structured chat off-win32. Keep the unconditional win32 refusal and
re-run the runtime resolution after it, so the gate does not depend on
the resolver's own platform guard. Tests inject WSL and repair-required
resolutions on darwin/linux and fail against the regressed gate.

a6e2379bd1 replaced this test with the in-flight settlement race test,

they are distinct (settled error clears on switch vs stale settlement

The two trailing CR bytes on the patch's deletion lines are a proven
no-op: pnpm hashes patches CRLF-normalized (both forms hash to the
lockfile's 946ffb2b) and materializes this package without applying the
patch in either form, so the load-bearing build edits come solely from
applyWindowsProcessTreeBuildFixes() (#16947), which handles both source
EOL forms. Restore byte-identity with main and repin the contract test
to the post-#16947 reality: LF-only patch bytes plus lockfile hash sync.

Brennan Benson ca0a6ec9be Stop the OS keyring probe from gating the first window on Linux (#16912)
* Stop the OS keyring probe from gating the first window on Linux

1.4.190 added an at-rest secret protection report and called it from the
`app.whenReady()` startup path, before the first window is created.
`describeProtectionGap()` asks Electron `safeStorage` whether the OS keyring
is usable, and on Linux that is a blocking D-Bus round trip to
`org.freedesktop.secrets`. A keyring that is present but locked with no unlock
prompter never answers, so the call sits until D-Bus times it out and the app
shows no window for over a minute.

Measured on Ubuntu 24.04 against a Secret Service that accepts the connection
and never replies, time to first window:

  1.4.188                          1.06s   (never contacts the keyring)
  1.4.190                         76.05s
  1.4.190 --password-store=basic   1.06s   (probe bypassed)

Nothing on the startup path consumes the report, so it now waits for the first
window's `ready-to-show`, with a timer fallback because that event can fail to
fire when the GPU cannot present and headless serve has no window at all. Same
build under the same hanging keyring: first window 80.48s -> 5.31s, with the
report still delivered.

STA-5765

* Pin the deferral the keyring-probe test exists to protect

The suite passed with the probe fired on browser-window-created instead of
ready-to-show, with setImmediate dropped, and with the fallback stretched to
10 minutes — every one of which reintroduces the STA-5765 stall. Drain the
queue before asserting and bracket the fallback so those mutations fail.

Also reformats the file to oxfmt.

* Report the keyring gap inline in headless serve

Deferring the probe to the first window is right for the desktop app, but serve
never opens one, so the fallback timer became its only path. That moved the
stall to after `printServeReady`: the runtime advertises itself, a relay or
mobile client pairs, and only then does the main thread freeze on the keyring —
stalling pings and PTY pumps, which a client reads as a dead host.

Serve now reports inline, which is the timing it already had, and blocks before
anything is advertised rather than under a live client.

* test(secrets): pin the once-guard against a late window reveal

The fallback can report first and the window reveal arrive after it; without
the guard that probes the keyring a second time, blocking the main thread just
as the user starts interacting. No existing case covered that order — removing
the guard left all six tests green.

* fix(secrets): keep the deferred protection report non-fatal, and pin the wiring

Deferring the report moved it off `whenReady`'s promise chain. A throw there was
an unhandled rejection the app survives; inside `setImmediate` it is an uncaught
exception, and `installUncaughtPipeErrorGuard` re-throws those fatally — so a
diagnostic the module documents as deliberately not fatal could kill the app.
Wrap the deferred call so it degrades to a warn. Serve keeps the inline posture.

Nothing outside index.ts referenced the scheduler, so reverting the call site,
or flipping `deferUntilFirstWindow`, left the whole suite green — including the
headless-serve regression an earlier review already caught once. Pin the wiring
as source text, following the host-port-bootstrap-wiring idiom with every anchor
bounded, and pin the two module gates that were only jointly covered.

* test(secrets): make the deferral wiring pin resist an inert call site

Round 2 of the review gamed the pin it had just added. Both anchors were bounded
against -1 but not against overshoot, and the marker matched anywhere in the
file — so nesting the call in a block, prefixing it with a guard, or commenting
it out all left three green tests standing over a call that never runs.

Bound the slice length, and anchor the marker to a statement at whenReady's own
indent. Commenting the call out, wrapping it in `if (...) schedule(...)` with or
without a block, and flipping the flag each redden now; previously only the
unused-import typecheck error caught the first.

Brennan Benson 2c86d2a3bd fix(agent-hooks): stop test runs and secondary profiles deleting the user's agent hooks (STA-5679) (#16980)
* fix(agent-hooks): stop startup from deleting another instance's managed hooks (STA-5679)

Startup reconciliation removed the managed agent hooks whenever THIS profile had
the agent-status-hooks off switch set. The hook files it removes are user-global
(~/.claude/settings.json, ~/.cursor/hooks.json), so a second Orca profile with the
switch off deleted the hooks every other running instance depends on.

Cursor is the only agent with no title-derived status fallback: its native title is
deliberately parsed as status-less, so a hookless Cursor pane is floored at 'idle'
rather than showing a spinner. A global hook wipe therefore surfaces as "Cursor
loading status missing from the sidebar" while Claude and Codex still paint status
from their own titles, which is why this reads as a Cursor-only bug. Codex is
unaffected either way because its hooks live in an Orca-owned runtime home.

Honoring the off switch only requires skipping the install; removal stays on the
explicit Settings toggle, which is the user-initiated path that should own it.

Regression from #2778, which restored the destructive startup branch.

* fix(cli-tests): stop the deferral suite deleting the developer's real agent hooks

runtime-client-deferral.test.ts runs the REAL `main()` and feeds it
`agent hooks off`. It mocks only ./runtime/environments and ./runtime-client, so
the production handler ran end to end: updateEnabledOnDisk() wrote its state file
and applyAgentStatusHooksEnabled(false) called removeManagedAgentHooks() against
the developer's OWN ~/.claude/settings.json and ~/.cursor/hooks.json.

A green test run therefore deleted every Orca-managed hook on the machine. Agent
status then stopped reporting until the next Orca restart reinstalled them —
silently, because the hook POSTs still return 204 and Cursor has no title-derived
status fallback at all.

The byte-for-byte equivalence twin already refuses these exact tokens, commented
"MUTATING — writes outside ORCA_USER_DATA_PATH (`agent hooks off` parks the real
~/.claude hooks)". The vitest twin never got that guard.

Stub the hook-controls module rather than dropping the row: `agent hooks off` is
the only case in the table that reads ctx.client, so it carries the
null-vs-undefined coverage the other four cannot. All 23 tests still pass, and a
sandboxed HOME now keeps its hooks (5 -> 5) where it previously lost them (5 -> 0).

* fix(cli-tests): ratchet agent hook deferral safety

* fix(agent-hooks): keep startup reconciliation install-only

Neilandinnocarpe f400f8fd5f fix(macos): opt out of press-and-hold so held keys repeat (#14746) (#15589)
* fix(macos): opt out of press-and-hold so held keys repeat (#14746)

macOS routes press-and-hold to the accent picker unless an app sets
ApplePressAndHoldEnabled=false for its own bundle, so holding j in vim
inserted one character instead of repeating. Orca never set it.

Written at most once, and never over an explicit value: `defaults read`
is domain-scoped and exits 1 when the key is absent, which is the only
way to tell "unset" from a deliberate false — Electron's
systemPreferences.getUserDefault reports false for both. A recorded
decision in userData keeps a later launch from re-clobbering a user who
deletes the key to get the accent picker back.

* docs(macos): record the revert hazard and CI's macOS test gap

Two things a reader of this module cannot otherwise know.

A revert leaves the key written in every user's domain forever. AppKit reads
the plist, not this file, so removing the code alone keeps press-and-hold
disabled for everyone who ran an affected build. The sibling period-substitution
module carries the same warning because that fix was already lost once this way.

And the real-binary test file that pins the defaults(1) exit-code semantics this
design rests on never runs in CI: the e2e workflow and both unit-test jobs are
ubuntu and windows, and the only macOS runners in the repo are build and
packaging jobs that run no tests. Those six tests plus the real-bundle e2e case
pass on a developer Mac and execute zero times in a green PR, so the comment
should not imply enforcement that is not there.

Refs #14746

* feat(macos): let users turn the accent menu back on (#14746)

Orca disables press-and-hold for its own preferences domain so held keys
repeat. That is the right default, but the way back was a `defaults write`
buried in a source comment: nothing in docs/ or the README mentioned it, and
the preference is per-application, so it silently takes the accent picker
away from the Markdown editor and every other text field too.

Terminal -> Advanced now carries a "Character Accent Menu" switch, macOS and
desktop only. A web client cannot write a macOS preference for the machine the
user is looking at, so the control and its search-index entry are both gated on
that, not on the client's platform alone.

Precedence, which is the part that is easy to get wrong: the setting is
`undefined` until the user touches it, which is what keeps a hand-run `defaults
write` in charge for everyone who never opens the toggle. Once used, Orca owns
the key and writes exactly what the switch asks for -- `ApplePressAndHoldEnabled`
*is* the accent-menu switch, so it maps straight through with no inversion. The
choice is compared against `appliedSetting` in the existing decision record
rather than against the domain, so a `defaults write` made *after* using the
toggle is still the newer choice and survives the next launch. Re-asserting the
value every launch would have reintroduced the clobbering the record exists to
prevent.

The write lands for the next launch, since AppKit reads the preference as the
process starts, so the toggle shows the same restart banner the window-blur
setting uses. That banner is now a shared component, keeping its original
translation keys.

docs/reference/macos-press-and-hold.md records the precedence rules, the
`defaults read` rationale, the revert hazard, and the fact that none of this
executes in CI: every macOS job builds or packages and runs no tests, so the
real-binary and e2e coverage here passes only on a developer Mac.

* docs(macos): stop asserting when AppKit re-reads the press-and-hold key

Five places stated "AppKit reads the preference as the process starts" as
fact. That is the reason given for requiring a relaunch, and it is not
something this change ever measured.

Evidence points the other way: terminal emulators that register this key
after their process has started get key repeat in that same launch, which a
read-once-at-startup model cannot explain.

The relaunch requirement itself still looks right, but for a different and
verifiable reason: the write goes out through a separate `defaults` process,
so this app's own cached copy need not observe it. That is what the comments
now say, with the AppKit question left open rather than answered.

Refs #14746

* docs(macos): correct the startup comment's launch-timing claim

The comment said this call site is "the last point that can still matter for
this launch", which contradicts the rest of the module: the write is assumed
to land for the next launch because it goes out through a separate `defaults`
process. Reported on the PR by @innocarpe, who also supplied the replacement
wording.

* refactor(macos): probe press-and-hold through the shared spawn chokepoint

`src/shared/child-process/child-process-import-boundary.test.ts` forbids a
direct `node:child_process` import outside its allowlist, and the allowlist only
shrinks — so this module moves to `runProcessSync`, which exists for callers
that genuinely cannot await. This one runs before `app.whenReady()`.

`runProcessSync` returns a non-zero exit instead of throwing it, so the
three-way read decision is re-expressed against `ProcessResult`: exit 0 is an
explicit value, exit 1 is a missing key, and a timeout, a signal kill, any other
exit, or a child that never started all stay 'unknown'. The throw path is now
inside `interpretDefaultsRead` so a spawn failure is reachable from a test
rather than hidden in an untested catch, and the write checks the exit code —
a refused `defaults write` no longer looks like success.

Both boundary-test failures were the same import: with it gone the offender
count returns to 155, so no ratchet baseline is bumped.

Neil 88ecc739e3 fix(browser): bound the agent-browser daemon's life instead of hoping teardown runs (#16367) (#16588)
* fix(browser): bound the agent-browser daemon lifetime (#16367)

`agent-browser` is a client/daemon CLI. Orca only ever spawns the short-lived
client; that client forks a daemon Orca holds no handle on, which reparents to
pid 1 immediately. Nothing in Orca reclaimed it, so a crashed or SIGKILL'd run
left one daemon per browser tab alive forever — two of them at ~25.6 GiB and
~7.2 GiB RSS saturated a 64 GiB cgroup under headless `orca serve`.

Three fixes, in order of how much they cover:

1. Set `AGENT_BROWSER_IDLE_TIMEOUT_MS` on both spawn paths (the bundled-binary
   bridge and the orcad external-Chromium provider). This is the only bound
   that survives every way Orca can die, including SIGKILL, where no teardown
   code ever runs. 10 minutes: >6x the bridge's 90s `EXEC_TIMEOUT_MS`, so it
   can never cut a command, a retry chain, or an ordinary gap between two user
   commands, while capping an abandoned daemon at minutes instead of days.
   Verified against agent-browser 0.27.0: an idle daemon exits and takes its
   Chromium tree and socket sidecar files with it, and a daemon attached over
   `--cdp` (the bridge's case) leaves the attached browser running, so an Orca
   tab is never closed by its daemon idling out.

2. Await `destroyAllSessions()` in the will-quit teardown barrier. It was
   fire-and-forget and the only browser member missing from
   `settleTeardownWithinDeadline`; each session's close is its own
   agent-browser child taking hundreds of ms, so `app.quit()` won.

3. Sweep daemons a previous run left behind, using agent-browser's own
   `session list` / `close` rather than a pid walk (see `windows-pty-job.ts`
   for why walking your own orphans is guesswork). `closeStaleAgentBrowserSession`
   only ever reset the one name a new tab was about to reuse. The sweep runs
   only when `AGENT_BROWSER_SOCKET_DIR` is set, because that private
   per-profile directory is what proves the enumeration can only see this
   Orca profile's daemons; it is never set on Windows, so Windows gets no
   enumeration rather than a machine-wide sweep that could close a daemon Orca
   does not own. Windows stays bounded by the idle timeout, which needs no
   ownership proof. orcad's session name is stable across runs, so it closes
   that one name at start instead — a killed orcad's daemon would otherwise be
   reused while still holding the previous run's Chromium on a dead serve port.

Where the 25 GiB went is inference from code, not a measurement: `captureStart`
sets `activeCapture` and only an explicit `captureStop` ends it, so a HAR
capture in a daemon living for days is unbounded. Not claimed as proven; the
idle bound caps it either way.

Not re-landed: the queue bounds from #10179 (reverted by #10255) bound Orca's
own main-process heap, not the daemon's RSS, so they do not address this report.

Also true but left alone: the 3-strike breaker's `destroySession` is an
unawaited call whose `close` is `catch {}`-swallowed, and it only fires while a
command is in flight — an idle-but-bloated daemon is never noticed. The idle
timeout now bounds that case. `getOffscreenBrowserBackend()?.destroyAll?.()` is
declared `void` and fully synchronous, so unlike `destroyAllSessions` it has no
promise to lose and needs no barrier entry.

* fix(browser): scope the daemon idle bound and close every daemon Orca owns

Review follow-ups on the agent-browser orphan fix.

- Never idle-bound the orcad external-Chromium daemon: it owns the user's
  remote browser, so the 10-minute bound closed a live session and every tab
  in it. Per-tab helper daemons keep the bound; the stable session name plus
  the `close` in start() is what reclaims a killed orcad's Chromium tree.
- Retire a page's daemon from the headless offscreen backend, which is the
  only place `orca serve` closes a page and never reached the bridge. Credit
  to @Jinwoo-H (#16564) for identifying this owner-boundary gap.
- Bound the teardown close at 5s so the will-quit barrier member cannot
  inherit the 90s exec timeout, and close sessions still being created.
- Gate the startup sweep on a socket directory Orca derived itself; an
  inherited AGENT_BROWSER_SOCKET_DIR is no proof of per-profile ownership.
- Replay a session's network routes when the daemon idled out between two
  commands, instead of silently serving unstubbed requests.

* fix(browser): give the orphan sweep a kill switch

Of the three behaviours this PR adds, two are already recoverable in the field
without a build: the idle bound is an env passthrough an operator can raise, and
the quit close is bounded by its own timeout inside the teardown deadline. The
startup sweep was the exception — it fires unconditionally, and if it closes a
daemon it should not, or spawns one process per stale name on a profile holding
hundreds, the only remedy was a revert.

ORCA_DISABLE_AGENT_BROWSER_SWEEP=1 turns it off, matching the existing
ORCA_DISABLE_CODEX_TRUST_RPC / ORCA_DISABLE_HTTP2 convention.

Note for anyone reaching for it on macOS: a Finder-launched Orca does not see
shell env, so it needs launchctl setenv or a terminal launch.

* fix(orcad): reuse a surviving browser session instead of closing the user's

start() closed the daemon before every open, killing the Chromium tree with it.
That runs on every provider start, not just after a crash — so an `orca serve`
restart took the remote user's browser and every tab in it.

The justification was borrowed from the pane bridge, which passes --cdp and so
really does hold a port that dies with its Orca. This session passes only
--session and --profile: nothing binds it to the old process, and the daemon
owns its Chromium independently. A survivor is reusable as-is.

start() now probes for an active tab first and returns it untouched. Only a name
that answers nothing gets closed and reopened — which is still the killed-orcad
case the stable session name exists to recover.

This matters more as orcad becomes the backend the remote host runs on: the
browser it manages belongs to a user, not to the process that happens to be
driving it this minute. It is also the same principle that already exempts this
path from AGENT_BROWSER_IDLE_TIMEOUT_MS.

Neil 26721bd632 fix(codex): stop blocking the main thread on trust grants (#16441) (#16594)
* fix(codex): stop blocking the main thread on trust grants (#16441)

Codex hook trust was granted by blocking the Electron main thread on
`spawnSync` of a bundled ELECTRON_RUN_AS_NODE entry for the whole
app-server deadline: 15s native, 35s WSL, ~45s on the real-home path
(rebase inspect + repair + grant). Cold start and every Codex pane
launch showed "Not Responding"; the reported event-loop gap was
15,049 ms.

The subprocess only ever existed to donate an event loop to a
deliberately blocked parent — `runCodexHookTrustGrantSession` was
already the real async implementation. Make the callers async and the
fork is unnecessary, so the bridge, the forked entry and its envelope
are deleted along with their build/knip/tsconfig registrations. The CLI
`agent hooks prepare-codex` handler is already async, so it awaits the
in-process session and saves a process spawn per managed-home shell.

`resolveCodexTrustGrantHost` is async too; the WSL identity probe moves
from `execFileSync` to `runProcess`, dropping that file from the
child-process import allowlist. Status reads keep a synchronous
native-only stamp path.

Two invariants that held only because the lane blocked:

- Overlapping capability probes were impossible by construction.
  `GitCapabilityCache`'s dedupe engine is extracted to a shared
  `CapabilityProbeCache` and `CodexAppServerCapabilityCache` now
  inherits it, so concurrent launches against a cold host share one
  app-server session instead of one each.
- Two grants on one `config.toml` could not interleave capture and
  restore. A reentrant per-file lane now serializes the whole install
  sequence (managed, WSL runtime, real-home ensure, legacy sweep) and
  the grant and rebase inside it.

Cold-start work moves off the critical path: retained-home
reconciliation (N sequential sessions) is fire-and-forget behind the
daemon provider, and the startup real-home ensure chains into managed
hook reconciliation instead of blocking app init.

Every preserved semantic is unchanged: never throws, the
ORCA_DISABLE_CODEX_TRUST_RPC kill switch, ledger hits, backfill-pending
and cooldown fallbacks, config rollback on every failure path,
pre-grant self-computed trust removal, the verify-failure taxonomy,
diagnostics and telemetry.

* fix(codex): widen the trust-config lane to every config.toml writer

Review follow-ups on #16441's async trust grant:

- `markCodexProjectTrusted` now runs inside the runtime+system config.toml
  lanes, so a project-trust write can no longer land inside a hook grant's
  capture->restore window and be silently reverted. Its callers await it.
- `install`/`refreshRuntimeUserHooks`/`remove` hold the system config.toml
  lane as well as the runtime one — they promote approvals into
  ~/.codex/config.toml and mirror it back. Lock order is runtime-before-system
  everywhere.
- The real-home ensure chain resumes after a rejection instead of returning
  the same rejected promise to every later pane launch, and resolving the real
  home is now inside the module's never-throws boundary.
- `buildSpawnEnv` awaits inside a cancelable pending-spawn registration, so
  shutdown during the (now long) env build stops the PTY from launching.
  `prepareLocalPtySpawn` generalizes into `awaitCancelableLocalPtySpawn`.
- CapabilityProbeCache drops the test-only `nowMs` passthrough; its probe
  backstop comment now describes what it actually guards.
- Preflight is a plain async function; the trust dispatch in orca-runtime
  collapses into one `markWorkspaceTrustedForAgent`.

* test(codex): exercise the trust-config lane under real concurrency

The async grant makes two pane launches overlap for the first time. These
drive the real modules end to end on real files: a rollback swallowing a
sibling's grant, a markCodexProjectTrusted write landing inside a capture
-> restore window, shared capability-probe dedupe on a cold host, the
host-scoped transient cooldown, and reentrancy from inside an installer.

Each was verified to fail against a deliberately broken implementation
(lane removed, dedupe disabled, cooldown made global, reentrancy pass-
through disabled).

* test(codex): stop hook-service suites spawning the developer's real codex

The forked grant bundle never existed under vitest, so the RPC lane was
unreachable in tests on main. Running it in-process makes these suites
spawn a real `codex app-server` when one is installed: 38 spawns and two
failures in hook-service-runtime-trust-repair on a machine with codex,
green in CI where there is none. Stand in for the missing binary so both
environments exercise the same fallback lane.

* docs(codex): scope the trust-RPC kill switch comment to what it actually gates

The comment read as though the flag forces the fallback lane everywhere. It
gates the managed grant only: the real-home rebase still runs its own
inspect/repair app-server sessions when Orca's insertion shifts a user's hook
positions, and never reads the flag.

Verified by exercise, not by reading — with the flag set, both
inspect-user-hook-trust and repair-user-hook-trust still ran. Pre-existing:
main has no check there either, it just blocked the main thread while doing it.

Widening the flag to cover the rebase is a follow-up; this only stops the
comment promising something the constant does not do.

Neil 96565fe370 perf(source-control): stop re-running every git read on each file selection (#15036) (#16600)
* perf(source-control): stop blocking main on four sync git-dir probes per status poll

detectConflictOperation ran four existsSync calls against the git dir on every
status poll. On a `\\wsl.localhost\...` worktree each one is a 9p round trip, and
being synchronous they landed on the Electron main thread back to back.

Replace them with concurrent fs/promises access probes: same "any failure reads
as absent" semantics existsSync had, one wave instead of four serialized blocking
calls. The outer try/catch went with them -- neither resolveGitDir nor the probes
can throw now, so it was unreachable.

Part of #15036 (source-control latency).

* perf(wsl): let git reads take the shell-free route from a cwd-derived distro

shouldAttemptWslDirectGit required options.wslDistro, so a `\\wsl.localhost\...`
worktree without a resolved WSL project runtime never qualified -- even though the
distro is right there in the cwd and wslDistroForCommand already knew how to read
it. Every `git show` behind a diff therefore ran through the user's login shell,
executing their rc once per blob read.

Three changes:

- Derive the distro from the cwd when no override was supplied. This is the fix;
  the routing decision now depends on where the repo actually lives.
- Wait, bounded, for a cold read-environment probe instead of resolving without it.
  The probe is one wsl.exe call shared per distro, so the wait is paid at most once,
  and past WSL_GIT_READ_ENVIRONMENT_WAIT_MS the shell route runs exactly as before.
  It returns null rather than a settled promise when there is nothing to wait for,
  so a non-WSL git call is not pushed into a later microtask.
- Opt the blob reads into preferWslDirectGit via gitReadOptionsForWorktree (renamed
  from gitStatusReadOptionsForWorktree; it was never status-specific). Belt-and-
  braces only: `show`, `config --get-regexp`, `ls-files` and `rev-parse` were all
  already matched by isWslDirectGitReadCommand, so this changes no routing today --
  it just stops the diff path depending on a heuristic it knows the answer to.

git-blob-read also gains a `failed` flag distinguishing "git ran and reported the
path absent" (exit 128) from "the read never got an answer"; nothing consumes it
yet, the settled diff cache does.

Part of #15036 (source-control latency).

* perf(source-control): give diff reads a settled cache keyed on stamped git state

gitDiffReadDedupe coalesces only while a read is in flight, so every file
selection re-ran the whole read: a `git config --file .gitmodules` spawn, one or
two `git show` spawns, and a working-tree stat+read. On a WSL/UNC worktree each
git spawn is a wsl.exe invocation, which is the ">3s Loading diff..." in #15036.

Correctness first -- a stale diff is worse than a slow one. The cache never
expires on a clock and there is no TTL to tune. Instead:

- worktree-diff-stamp.ts takes a subprocess-free stamp of exactly the inputs a
  file diff is built from: HEAD (by resolved tip *content*, so a commit is
  visible even though HEAD's own bytes never move), `.git/index` (mtime+size),
  `.gitmodules` (submodule routing), and the working-tree file. A linked
  worktree's commondir and the packed-refs/reftable fallback are handled; an
  unborn branch is caught by recording "no loose ref" rather than only the
  packed stamps.
- The stamp is captured BEFORE the read and stored with the result. Anything
  that moves during or after the read leaves the stored stamp behind, so the
  next lookup misses. That, not a freshness window, is why a stale diff cannot
  be served.
- A store is refused unless the stamp was taken a full mtime bucket (2s, FAT's
  granularity) after its newest component. Below that, a second write inside the
  same bucket would be invisible -- git's own racy-index rule.
- `null` stamp means "cannot prove" and never caches: a folder workspace, a repo
  whose layout cannot be read, or a filesystem reporting no usable mtime.
- Submodule routes and reads that failed rather than proved absence are not
  reusable. A wsl.exe hiccup produces the same empty left side a new file does,
  and pinning that would persist a wrong diff.
- invalidateGitReadCaches clears it and bumps a generation, so a read that
  started pre-mutation cannot store its result post-mutation.

`ino` is deliberately optional in the working-tree component: Windows reports 0
for it on the redirector behind `\\wsl.localhost`, and requiring an unstable 0 to
match would make the cache silently never hit on the exact host it exists for.
Cache counters are exposed for the same reason -- a miss storm and a cold start
otherwise look identical.

Also drops gitDiffReadDedupe.clear() from getStatus. A status poll is a read; all
it did was destroy a live coalescing entry so a concurrent identical request
started duplicate git work. Mutations still invalidate through the shared point.

Memory is bounded by retained characters, not entry count -- one diff result can
legitimately hold megabytes.

Fixes the source-control half of #15036.

* perf(source-control): reuse BoundedMap and stop the WSL probe wait from outliving its answer

Review follow-ups on the settled-diff-cache work:

- SettledDiffCache now sits on the shared BoundedMap instead of hand-rolling the
  same Map + character ledger + evict-oldest loop.
- pendingWslDirectGitReadEnvironment returns null once the probe has settled
  either way, so a distro whose direct route was disabled no longer pays for a
  1.5s timer and two microtask hops on every git read.
- That wait now honours the read's abort signal and goes through withTimeout, so
  an aborted read is not held for the full bound and a probe rejection can never
  surface as a read failure.
- The settled-cache generation fence is taken before the stamp read, so a
  mutation that lands entirely inside the stamp's stats can no longer store an
  entry whose stamp is torn across it.
- The cache counters are folded into the main-thread churn probe report, which is
  what tells a permanently-cold cache apart from a cold start in the field.

* fix(source-control): tell WSL clock skew apart from a genuinely fresh write

The racy-write margin compares two clocks: capturedAtMs is this host's, while
the component mtimes come from whatever wrote the files. On a \\wsl.localhost
worktree the guest sets them, so a guest running ahead pushes every
recently-touched file past the margin and the cache refuses to store — for as
long as the skew lasts, on exactly the platform this cache exists for.

Nothing was wrong with the refusal; it was invisible. racyWrites alone cannot
distinguish "the repo was just edited" from "the clocks disagree and this will
never resolve on its own", so a permanently cold cache looked like a cold start.

isDiffStampClockSkewed flags the one thing no local write can produce — an mtime
in this host's future — and the cache counts those separately as
clockSkewedWrites. A nonzero count is the signal that the cache is off for a
reason idling will not fix.

Neil 015f904fca fix(codex): stop re-scanning all Codex session history on every launch (#16251) (#16593)
* fix(codex): stop re-scanning all Codex session history on every launch (#16251)

A launch deleted the backfill completion marker, and a marker could never
be written while a Codex pane was open, so every launch re-derived
"needs full scan" and walked the entire .codex/sessions tree — on Windows
with a large history that read as a hung window.

- v4 marker keeps a durable full-history baseline plus a bounded set of
  pending dates. v3 is read as a baseline, so upgrades pay no full scan.
- A launch now marks dates pending instead of deleting the marker, and a
  full pass certifies the baseline even while a pane is still running;
  the live pane's own date just stays pending.
- Pending dates are persisted, so an abnormal exit or a cross-midnight
  pane recovers a bounded window instead of a full walk.
- A date-limited pass can only extend an existing baseline, never create
  one, so it can no longer certify history it never looked at.
- Marker and index-heal target roots compare through
  normalizeRuntimePathForComparison, so Windows spellings of one
  directory stop invalidating each other.
- Both append-only ledgers stream instead of readFileSync + whole-file
  JSON.parse, keeping the main thread responsive on large histories.

* fix(codex): keep the backfill marker's full-scan demand durable

Review follow-ups on the v4 backfill marker:

- markCodexSessionBackfillMarkerPending no longer erases a persisted
  needsFullScan; the demand survives until a generation-current full walk
  retires it, and the function now reports it so the launch path folds it
  into its own in-memory flag (as @rumoii's #16252 does).
- A full pass settles the whole pending set instead of subtracting the
  empty set, so a date a full walk provably covered stops forcing an extra
  bounded pass on every startup.
- isCodexSessionBackfillDate does a real calendar check, so a corrupted
  marker cannot carry 2026/99/99. No age or future bound: the same guard
  gates rollout publication and a clock-skewed directory holds real
  sessions.
- 'scans only the current date once a baseline exists' now has a second
  date directory, so it fails on a full walk instead of passing either way.

Brennan BensonandSiddiqui Qamar 5a59bc5bc4 fix(grok): stop Orca's Grok hooks from costing anything outside Orca (#16666)
* fix(grok): stop Orca's Grok hooks from costing anything outside Orca

Orca registers Grok agent-status hooks in the global $GROK_HOME/hooks. Grok
loads that directory on every session, so a Grok run that Orca did not launch
still paid for the hook on every event, and Orca rewrote the file even after a
user had emptied it to opt out (#15518).

The registered POSIX command now guards on ORCA_PANE_KEY before doing anything.
That variable is part of the pane identity Orca injects into terminals it
launches, and unlike the port and token it never comes from the endpoint file,
so it is present exactly when the session belongs to Orca. A standalone session
short-circuits without spawning a shell for the managed script at all. The same
guard is applied to the remote install, because a remote host runs standalone
Grok sessions too.

PreToolUse is no longer registered. It is a blocking hook, so Orca sat on the
critical path of every tool call and doubled the per-tool spawns, for a
transition PostToolUse already reports.

Windows cannot use the guard: the command there must be a single spawnable
token, so it is a bare script path with no shell to evaluate a test. For that
case the hooks are removed when Orca quits -- locally, on WSL guests, and on
connected SSH hosts -- and reinstalled on the next launch. A config the user has
emptied is left alone on startup; turning the setting back on in Settings is an
explicit and later choice, so that path reinstalls.

Removal is careful about what it is deleting. It strips only Orca's own entries,
keeps user-authored ones, and deletes the file only when no hook entries remain
-- keying that off the whole object would leave a stray non-hook key behind, and
the emptied-config check would then read that remnant as a deliberate opt-out
and never reinstall. A config the user has symlinked into a dotfiles repo is
written through rather than unlinked, and is exempt from the emptied-config
check for the same reason: after a quit it is a file Orca emptied, not one the
user did.

Writes go through temp+rename. Grok refuses to build a sandbox profile for a
hook JSON with more than one hard link, so publishing by hard link would fail
any session that started during the write.

Install and removal on remote hosts now read the platform from the same field.
They did not, so a Windows remote whose bridge env was incomplete had hooks
installed and never removed.

Jinjing cda2280d63 Show all automations (#16532)
* Add all-host automations with scoped ownership and multi-authority suppo

Enable automations to run on multiple hosts (SSH targets and local) with
owner-fenced mutations, scoped list queries per host, and conflict
resolution. Introduces desktop and runtime authorities as distinct
automation storage owners, with per-host caching, invalidation, and
retry scheduling on the renderer. Captures registration generations for
SSH hosts to survive re-adoption. Adds CLI support for destination
selection and conflict recovery.

* Filter automation create projects by destination host

Only offer projects available on the selected destination, preventing
the mismatches that would fail at submit time. Auto-adjust the project
selection if it becomes unavailable when the destination changes.

* Add runtime storage authority support for automations

- Support both runtime and desktop as automation storage authorities
- Make owner preconditions optional for legacy-client compatibility
- Cache automation list projections to improve performance
- Add per-row repo/worktree resolution for cross-authority collisions
- Extend automation.list RPC to always include owner metadata

* Replace child_process.execFile with runProcess for external automations

- Migrate external-manager to use cross-platform runProcess wrapper per child-process safety policy
- Abstract electron app/ipcMain APIs in orca-runtime via environment accessors
- Install fake app environment in automation tests for consistent setup
- Reorganize imports to use specific module paths (ssh-target-registry, agent-detection, browser-error)
- Remove external-manager from child-process import allowlists (no longer violates direct import)

* Unify desktop automation CRUD onto the local runtime RPC surface

The desktop authority now speaks the same automation.* RPC contract as
remote runtimes, via callRuntimeRpc({kind:'local'}) -> runtime:call ->
the shared RpcDispatcher. The automations:list/listRuns/create/update/
delete/runNow IPC arms, their preload members, and every renderer
desktop-vs-runtime transport fork are retired; the runtime methods are
the single implementation of scoped lists, owner fencing, and change
publication for both transports (mobile clients already exercised them).

The desktop probe scheduler's priority lease survives the move as an
AutomationService hook the IPC registration installs and the runtime
methods take, so Orca's own automation traffic still parks queued
external-manager probes.

External-manager scope arms and dispatch-loop plumbing stay on IPC by
design; automation change events keep their existing channels (renderer
ingestion already converges them by authority).

* Remove automation ghost SSH tombstone scanning

This functionality for synthesizing tombstones for automation-referenced SSH
targets is no longer needed as part of the automation system refactoring.

* Refuse orphan automations at dispatch time, not migration time

Remove migration-time disabling of orphan automations and the `enabledDecidedBy` field. Dispatch now refuses orphans at runtime instead, simplifying state management and UI. Orphans are left unstamped and enabled; dispatch refuses to run them via `resolveAutomationRunTarget`.

* Show all automations in flat table with unified filter menu

- Replace host picker component with comprehensive Filters menu supporting status, last run, agent, and host filters
- Flatten automation list layout to single table instead of host-grouped sections
- Add Host column to display execution host for each automation
- Display active filters as removable pills below toolbar
- Delete unused AutomationHostPicker* components

* Add automation owner fencing and destination validation

- New AUTOMATION_OWNER_FENCING_RUNTIME_CAPABILITY for owner preconditions; legacy clients get owner metadata snapshotted at RPC boundary for compatibility
- Editor captures and revalidates automation destination before save, preventing silent retargeting if SSH infrastructure changes mid-edit
- SSH target types now isolate renderer-authored fields; generation is server-owned and stripped by IPC handlers

* Route automation recovery actions to the origin host

When an automation action fails due to owner fencing, recovery verbs
("Update server", "Reconnect") must run on the host where the refusal
originated: the row's captured owner for row operations, or the
destination the create dialog captured, not the list's filtered host.

* Remove external manager scope limitation notices

Consolidate create destination eligibility checks with a unified predicate
and fix the bug where desktop repo IDs could be sent to runtime hosts where
they cannot resolve.

* Persist only store-derived automation contexts, not client-perspective o

Store contexts must never be based on client-provided runContext or sourceContext
values—clients speak a different perspective (e.g., 'runtime:<id>' for host IDs
they assign), and persisting those makes the store projection orphan automations
it actually owns. Derived contexts now take precedence in create and update paths,
with explicit null still honored to clear a value. Tests verify this by simulating
drift after storage and confirming that moves re-derive while toggles preserve.

Jinjing e361da7fb7 Deleting skill (#16357)
* Add skill deletion with cross-platform transaction safety

Implements end-to-end skill removal with placement enumeration, dependency guards, and transactional recovery. Covers native, WSL, and remote hosts; users can delete canonical directories and alias placements (symlinked directories or files) in a single atomic batch. Includes UI selection flow, preview, confirmation, and results band. Block reasons (bundled, plugin, unowned, stale) gate deletions that would fail or contradict user intent.

* Organize IPC handlers into module subdirectories

Move register-core-handlers and skill-delete-ipc-handlers into
dedicated subdirectories for improved code organization and to
reduce the flat structure in src/main/ipc/.

* Make skill deletion recovery transactions idempotent

Defer journal cleanup until both staging removal and receipt cleanup succeed, leaving the journal in place for startup to retry if either operation fails. This ensures the recovery process is safe to run multiple times without leaving partially-deleted skills.

* Consolidate skill-delete files into dedicated module

Reorganize skill deletion functionality into a modular structure under
`src/main/skills/skill-delete/` with simplified file names. Remove the
redundant `skill-delete-` prefix from file names since they now live in
the dedicated directory. Update all import paths throughout the codebase
to reflect the new structure, including imports from IPC handlers and
RPC methods.

* Fix broken import paths and add deletion robustness improvements

Import paths using `..//'` were invalid and broken. Replace with explicit
module names (`skill-discovery-sources`, `skill-install-filesystem`, etc.)
to clarify dependencies.

- Bind WSL filesystem methods to preserve `this` context
- Keep recovery journal when rollback rename fails, so startup can retry
- Skip symlink-based tests on Windows where they cannot run
- Only treat ENOENT/ENOTDIR as empty directories; propagate other errors
- Fix cross-platform path parent calculation to handle drive roots
- Replace shared constant with localized string for user-facing message
- Use `runProcess` for WSL integration test instead of bare `execFile`

* Add batch limit for skill deletion and improve host availability checkin

- Limit concurrent deletions to prevent remote host overload
- Add retry logic for capability probing to handle transient unavailability
- Add reprobe() method to recheck capability after errors or user refresh
- Fix status logic: receipt cleanup is best-effort, completion depends only on content removal
- Improve error message for unreachable hosts

Neil 4218d5068e fix(cli): seed nvm's default version, not the newest install (#16420)
* fix(cli): seed nvm's default version, not the newest install

#16314 stopped the login-shell probe inheriting the seeded PATH, but left the
seed itself picking the newest installed nvm version. That ordering decides
which node a CLI runs under whenever the probe does not land — a timeout, or a
login shell whose rc never initializes nvm — and newest is precisely the wrong
guess: it is usually the version the user just added and has installed nothing
into. That is the root cause reported in #10932.

Resolve `alias/default` instead, mirroring nvm: follow the alias chain
(`default` -> `lts/*` -> `lts/krypton` -> a version), resolve a partial version
like `24` to the highest matching install, and treat `system`/`node`/`stable`
as no preference. The chain is bounded and cycle-guarded because nvm's own
resolver tracks seen aliases and hand-edited files can point at each other.

Ordering is a preference, not a restriction: the remaining versions stay behind
the default, so a CLI installed outside it is still reachable.

Measured on a real machine with nvm default=24 and a bare v26.7.0 installed:
the old resolver seeds v26.7.0/bin (no CLIs), the new one seeds v24.18.0/bin
(every CLI). Tests were written first and verified to fail on the three bug
cases against main before the fix existed.

Also raise the probe budget from 5s to 10s. The old value was never measured
against a real profile: a bash -ilc loading nvm, rvm, conda and gcloud takes
~1s idle but 6-7s on a loaded machine, so a cold start under load silently
fell back to the seed. Startup does not block on the probe, and the one
awaited consumer is agent detection, which is better served by a probe that
finishes late than one that gives up early.

* fix(cli): reject non-version alias tokens instead of matching v0.x

Review finding, and a real bug I introduced. parseVersionSegment coerces
every unparseable segment to 0, so an unresolvable default alias — `garbage`,
`iojs`, `lts/nonexistent`, any hand-named alias — became [0] and prefix-matched
a `v0.12.x` install, or any stray non-version directory. Orca would then seed a
decade-old node as the preferred runtime. Real nvm answers N/A for all of them.

The `wanted.length === 0` bail could never have caught this: ''.split('.') is
[''], never empty. Replaced with a shape check that still admits legitimate
numeric prefixes — verified against nvm itself, which resolves `24` to
v24.18.0 and `0` to an installed v0.x while answering N/A for the rest.

Also corrects two comments that no longer described the code: the seed is no
longer "newest install", and the probe budget note claimed startup never blocks
on hydration, which is false on packaged Windows where it gates terminal
services and git. The traversal-guard comment claimed a containment join()
already normalizes away; the real guarantee is that matchNvmVersion can only
return an entry of the versions directory.

* fix(cli): match nvm's version-token grammar, not just its first character

Round-2 review finding, and the same bug one layer down. The previous guard
anchored only the first character, but parseInt stops at the first non-digit,
so `0x18`, `00` and `0abc` still parsed to [0] and prefix-matched a v0.12.x
install — the decade-old-node seed the earlier fix was supposed to close.

Reachable: `nvm alias default 0x18` warns that the version does not exist and
writes the alias anyway, then resolves it to N/A.

Use nvm's actual grammar, leading zeros included — nvm calls `00` and `024`
N/A while parseInt reads them as 0 and 24. Verified by executing 17 tokens
against a five-version fixture: every one now agrees with nvm, including the
legitimate prefixes `0`, `0.12`, `24` and `v24.18.0`.

Also drops a dead disjunct (the hop bound already caps the loop, so seen.size
can never exceed it) and corrects the log comment in index.ts, which still
told the reader a failed probe leaves the newest install in front. It leaves
the default version in front now, which is usually survivable but still not
what the shell would have resolved.

* test(cli): skip the lts/* chain fixture on Windows

Round-3 review finding. makeNvmHome materializes each alias as a real file,
and the chain case uses nvm's actual `lts/*` alias — `*` is a reserved Win32
filename character, so writeFileSync fails with EINVAL. PR CI runs a Windows
allowlist that excludes this file, so the breakage only reaches a Windows
developer running the suite locally.

Skipped rather than renamed: `lts/*` is the alias nvm really ships, and the
assertion pins platform: 'darwin' anyway, so the real name costs no coverage.
Matches the skipIf convention already used across src/shared.

Also reflows a comment line that a previous edit ran to 143 characters;
oxfmt does not reflow comments, so nothing would have caught it.

Neil 5c116b6ec2 fix(startup): stop the PATH seed pinning nvm to its newest install (#16314)
* fix(startup): stop the PATH seed pinning nvm to its newest install

patchPackagedProcessPath prepends the newest nvm version dir to
process.env.PATH, then hydrateShellPath probes the login shell with that
same env. nvm's startup `use` honors whatever node is already on PATH
instead of the user's `default` alias, so the probe returns a PATH pinned
to the newest install and every terminal pane inherits it.

A user whose newest nvm node is a bare install then loses every global CLI
(codex, claude, gemini, vercel...) inside Orca while they still resolve in
Ghostty/Terminal, which start from the bare GUI PATH and fall through to
`default`.

Probe with the PATH the process launched with. Windows already gets this
through WindowsShellPathOwnership.

* test(startup): pin the platform in the probe-env test

shellProbeEnv short-circuits on win32, so the POSIX-only assertion failed
for anyone running the suite on Windows. Matches the convention in
hydrate-shell-path.windows.test.ts.

Also narrows the win32 exemption comment: WindowsShellPathOwnership
snapshots its baseline after the seeds land, so it does not unwind them.
The exemption holds because Windows keys PATH as `Path` and no Windows
seed pins a node version.

* fix(startup): give win32 the same probe insulation, keyed by Path

The previous commit exempted win32 on the stated grounds that no Windows
seed pins a node version. That is wrong: getVersionManagerDirectories
calls getNvmVersionDirectories on every platform, so a Git Bash user whose
nvm uses the POSIX ~/.nvm/versions/node layout gets the newest version dir
seeded on Windows too, and the -ilc Git Bash probe inherits it.

Record the PATH key alongside the value and overwrite that entry in place,
so Windows never carries both `Path` and `PATH` — which was the only real
reason to skip win32.

* fix(startup): snapshot the launch PATH at module load, log probe failures

Three loose ends from the review, folded in rather than deferred.

The probe's clean PATH was handed over by an explicit recordLaunchPath call
from the seeding site, so the invariant lived across three files and a
refactor that moved the seed call would silently re-pin nvm. Snapshot PATH
during module init instead: that runs while the import graph is evaluated,
strictly before any statement in main's body, so it cannot observe the
seeds and there is no call ordering left to break. All seven importers are
static, so no lazy import can defeat it. A test asserts the probe ignores
later process.env mutation, and fails if the live read is reintroduced.

A failed startup probe leaves the seeded newest-nvm dir in front and said
nothing, so the population whose rc files blow the 5s budget hit the
original symptom with no diagnosable trace. Log the failureReason.

The probe is an interactive login shell, so rc files that exec into a
multiplexer or start a heavy prompt can outrun that budget with no way to
opt out. Set ORCA_SHELL_PATH_PROBE=1 so they can take a fast path.

* fix(startup): drop the other-cased PATH key from the Windows probe env

Caught by running the suite on a real Windows machine, not a mocked
platform. The spread of process.env is a plain, case-sensitive object,
while Windows resolves env names case-insensitively. Writing the captured
`Path` back onto it left the seeded value still live under `PATH`, so the
probe shell could read either one — the exact duplicate-key hazard the
win32 branch was supposed to prevent.

Drop any other-cased variant of the key before writing.

Brennan Benson 94f231737d fix(agent-status): retire panes whose agent process is gone (STA-4612) (#15212)
* fix(agent-status): retire panes whose agent process is gone (STA-4612)

Agent status can hold `working` on a pane where no work is outstanding, and
nothing closes the gap. A pane's Claude state is a join of a lead turn and three
latches — the subagent roster, the background-task gate and the session-cron gate
— and each is set by a hook and cleared only by another hook. Claude Code emits
no terminating hook on `/exit`, `/clear`, Ctrl+C, crash, SIGKILL or terminal
close, so every one of those latches is a claim with no owner and no expiry. The
join is also materialised at ingest time and persisted, so a stale `working`
survives restart and blocks hibernation, which requires `done`.

Registering `SessionEnd` is not the fix: it covers roughly a third of exit paths
(measured on 2.1.231/2.1.233; upstream anthropics/claude-code#17885 and #6428 are
both closed as not planned). Nor is a TTL — `AGENT_STATUS_STALE_AFTER_MS` only
decays the sidebar dot at read time while the stored row stays non-terminal.

So the backstop is built from evidence Orca already owns.

A session id that changes means the conversation was replaced. On the first hook
of the new session — whatever that hook is — the previous session's own claims
are void: its session crons and its one-shot subagents. Deliberately not voided:
the background-task gate (a background shell is an OS process that survives
`/clear`, and the previous inventory is positive evidence it was running), and
`confirmedTeammate` rows (persistent in-process teammates a lead swap cannot
end). The lead record is left to the incoming event's own fold.

A certified process exit retires the pane. Orca already does this on every
attributable PTY exit — `clearProviderPtyState` resolves the pane key and calls
`clearPaneState` — but that resolution depends on the spawn-time `ptyPaneKey`
mapping, which a restored or reattached PTY may never rebuild. Those panes keep
their row and latches for good. `onPtyExit` knows the keys teardown could not
resolve, so it reconciles them from its own records. The certificate is
`exitCode >= 0 || hostExitConfirmed || providerExitObserved`: a synthetic `-1`
from a failed stop is not a death (the PTY can have survived it), while a real
exit can also report `-1`, so neither the code nor the SSH surface predicate is
sufficient alone. `providerExitObserved` is additive and separate from
`hostExitConfirmed`, which also drives the liveness verdict and the SSH surface
decision.

A confirmed shell foreground is the `/exit` case: the agent died, the shell
lived. That already dropped the row, but through `agentStatus:drop`, which by its
own contract preserves a live pane's caches — so every latch survived and the
next event resolved the pane back to `working`. It now routes through the
reconciler instead, gated on a per-pane accepted-status generation rather than
row identity: the confirming process read can take seconds, and `updatedAt`
cannot order two writes inside one millisecond (the store deliberately admits
equal timestamps).

Cold start generalises the same way. The startup sweep required a restored
subagent roster, so a stranded lead row, background-task gate or cron gate — the
shapes with no child event left to reap them — were never candidates.

Hibernation needs no change: with the above, those rows become genuinely `done`
and the lockout resolves through the front door. A `restoredUnconfirmed` bypass
in the planner would let it reclaim the heap of an agent that may be working.

Not included: folding `background_tasks` from a child-attributed `SubagentStop`.
Writing its test surfaced #11838's deliberate assertion that child inventories
are not authoritative for lead-owned background work, and the listener says the
same — "background_tasks is trusted only where unambiguous". An empty list on a
`SubagentStop` does not prove the lead's shell ended, so the fold would have
cleared a gate on evidence that establishes nothing.

STA-4119's live-side question — whether a genuinely live background shell should
hold the lead row after the lead turn ends — is untouched. This change extends
gate-clearing to zero new triggers.

* fix(agent-status): make the confirmed-shell reconcile survive its own drop

The /exit leg never fired. `settleDeferredCommandFinishedStatusDrop` runs the
paired drop before the reconcile, and `dropAgentStatus` cleared the per-pane
accepted-status counter the reconcile's guard then read — so the guard compared
a live anchor against a zeroed counter and skipped itself on every pane that had
a status row, which is every pane worth reconciling. The existing test passed
only because it used a pane with no row, where the drop early-returns and both
sides read 0.

Stop keying the guard on a counter a sibling teardown path can reset: the
ordinal is now stamped on the row itself, derived from the row it replaces, so
there is no side table to clear and a batched burst lands the same ordinals as
the equivalent sequential writes. A removed row means "nothing reported", which
is exactly what the paired drop leaves behind.

Also:
- Keep the `providerSessionOnly` resume identity that the paired dismissal mints
  when the shell outlived the agent; a certified PTY exit still takes it, since
  there is no pane left to resume into.
- De-vacuum two guard tests. The confirmed-teammate pin never anchored a session
  owner, so the void it claimed to survive never ran; the unavailable-inspection
  pin asserted before the confirm ladder settled. Both now fail when their guard
  is removed.
- Derive `hasLiveClaimsForPaneKey` from a predicate that lives beside
  `clearPaneCacheState`, so a new latch cannot be added to the teardown and
  silently missed by the claim check.
- Drop the unreachable compact-`trigger` clauses; SessionStart is the whole guard.
- Cover the connectionId arm of the exit certificate, where a provider-observed
  death and a preserved SSH surface are deliberately independent.

* fix(agent-status): keep agent-status-types under its line cap

main already sits exactly at the 300-line max-lines cap for this file, so the single
`acceptedStatusSeq` field this branch adds pushed it to 301 once main's observation
facet merged in.

Declared the field as a mixin beside the observation facet instead. Both are per-write
facets mixed into `AgentStatusEntry` rather than fields a reporter supplies, so they
belong together — and the capped file loses a line rather than gaining one, since it
already imports from that module. No lint suppression.

* fix(agent-status): collapse the entry facets into one intersection

The previous attempt still tripped max-lines: two mixins on one intersection wrap
across two lines under oxfmt, so removing the field line bought nothing.

Expose a single AgentStatusRowFacets that already includes the observation facet, so
the entry intersects one short name on one line. The payload keeps intersecting the
observation facet alone — it must not carry the renderer-local ordinal.

Verified by formatting first and then linting, which is the order that catches this.

Neil 1375c57b16 fix(secrets): report the protection gap on change, not on every launch (#16044)
The gap warning fired every startup with no way to stop it. It usually needs a
keyring installed and unlocked to fix, so repeating it every launch is nagging
the user cannot act on and will learn to ignore.

It now reports when the answer changes: once when the gap starts being true,
again if it becomes true for a different reason, and once when it is fixed —
because silence after a "your secrets are not protected" warning would leave the
user assuming that is still the case.

State lives beside the profile data file, which is why the call moved out of the
port bootstrap: that state has nowhere to live until the profile exists. A
corrupt state file re-reports rather than trusting it, and a failed write logs
instead of failing startup, since re-reporting next launch is the safe direction.

ORCA_ALWAYS_REPORT_SECRET_PROTECTION=1 forces a re-report for support without
disturbing the stored state.

Neil 838f5bfb75 fix(secrets): tell Linux users when their secrets are only obfuscated (#16033)
On Linux with no keyring, Electron falls back to the `basic_text` backend, which
"encrypts" with a hardcoded password. `isEncryptionAvailable()` returns true for
it, so Orca reported those secrets as sealed. They are not.

The obvious fix — returning false for basic_text — is wrong and would have been a
credential regression: `decryptWithStatus()` skips decryption entirely when
encryption is unavailable, so every already-stored secret would read back empty.
Sealing genuinely works on basic_text and must keep working.

So capability and trust are now separate questions. `isEncryptionAvailable()`
still answers "can this host seal and unseal", and `describeProtectionGap()`
(renamed from `describeUnavailable`) answers "is my data actually protected",
covering both no-sealing and weak-sealing.

That method had no production caller — the port documented a promise nothing
kept. `reportSecretProtectionGap()` now reads it at startup. A user-visible
surface is follow-up; this at least stops the silence.

Adds a bootstrap wiring guard over all nine host port installs. The no-op
defaults are correct for a renderer-less host and silently wrong for the desktop,
and a dropped or reordered install fails no existing test. Verified in both
directions: it fails when an install is removed, and when one moves after the
runtime is constructed.

Neil 03fcfdfb92 feat(orcad): boot the Orca runtime on plain Node (#15968)
* refactor(host): resolve the app root through the port in fork-reachable modules

`parcel-watcher-entry-path.ts` and `session-scanner-service-entry-path.ts` read the
app root via `require('electron').app` inside a try/catch that already returns null
when Electron is absent. They were therefore correct under plain Node at runtime and
only failed the *static* text check — which is real, not pedantic: the comment in
`ports/port-scan-command-client.ts:19` records that the plain-node-entry-guard fails
on that literal text, try/catch or not.

`hasAppEnvironment() ? getAppEnvironment() : null` gives the identical "no app root
here" answer without the text. That restores `hasAppEnvironment`, which an earlier
commit in this stack deleted as unused — it now has the caller it was waiting for.

Ratchet baseline 27 → 25.

Verified: 74 files / 458 tests; `pnpm typecheck` clean; `oxlint` clean.

* feat(orcad): boot the Orca runtime on plain Node

Closes the last two Electron couplings and makes `orcad` a working artifact:
a 4.43 MB Node bundle that boots, pairs, registers a repo, creates a real git
worktree and round-trips a PTY — with zero `require("electron")`.

Ratchet 2 -> 0, so `config/runtime-electron-baseline.txt` is now empty and its
test asserts exactly that: any reachable electron import is a regression.

- speech: inject the service factories, so importing ModelManager for its type
  no longer drags Electron's streaming net.request into the graph
- filesystem-watcher: add a WorktreeWatcherRemoval port. Every entry in those
  maps arrives through an ipcMain handler carrying a renderer sender, so a host
  with no renderer has nothing to close, restore or forget — the inert default
  is what the desktop code does against empty maps, not a stub hiding work
- user-data-path / profile-storage-paths: resolve userData through
  AppEnvironment. These surfaced only once orcad pulled the store in

Both host ports now anchor to a realm-global symbol. `vi.resetModules()` gives
the re-imported graph a fresh module copy, so a binding installed before the
reset silently read back as uninstalled.

The acceptance smoke drives both hosts through one code path (`--target
orcad|electron`) and seeds its own git repo, so it is hermetic and asserts the
same contract of each. Wired into PR CI.

* test(smoke): remove the seeded workspace container, not just the worktree

* test(smoke): surface the server's stderr when it dies before ready

* fix(smoke): build node-pty for Node before booting orcad in CI

* fix(smoke): drive the CLI built from this checkout, not one on PATH

* docs(ratchet): say the baseline must stay empty, not merely shrink

* build(orcad): externalize only the native modules actually in the graph

Neil f975035809 refactor(ipc): split preflight and SSH registry out of the ipcMain modules (#15927)
* refactor(preflight): split agent detection out of the ipcMain registration

First of the IPC extractions the revised design requires. `src/main/ipc/preflight.ts`
mixed 285 lines of agent/tool detection with 35 lines of `ipcMain.handle`
registration, and the runtime calls that detection during normal operation
(`orca-runtime.ts:573`, plus the preflight RPC methods). So the runtime dragged
`ipcMain` into its graph to reach pure logic.

Detection moves to `src/main/preflight/agent-detection.ts` — named for what it
contains, per AGENTS.md. `ipc/preflight.ts` keeps only the handler registration and
re-exports the domain module so existing importers are unaffected. The runtime and
its RPC methods now import the domain module directly.

Ratchet baseline 36 → 35: `src/main/ipc/preflight.ts` is no longer reachable from
the runtime. The gate detected the improvement and refused to pass until the
baseline tightened, which is the behaviour it was built for.

Verified: 2 files / 1,187 tests pass across every suite touching preflight;
`pnpm typecheck` clean; `oxlint` clean.

* refactor(ssh): split the SSH target registry out of the ipcMain module

Second IPC extraction, and by far the biggest win: this removes **eight** modules
from the runtime's Electron graph, taking the ratchet baseline 35 → 27.

The runtime needed five thin accessors from `src/main/ipc/ssh.ts` —
`connectRegisteredSshTarget`, `getRegisteredSshState`, `listRegisteredSshTargets`,
`listRegisteredRemovedSshTargetLabels`, `getActiveMultiplexer`. Each is a one-line
read over module-level state. Importing them dragged in `ipcMain`, `powerMonitor`
and a `BrowserWindow` accessor — and, transitively, `ipc/pty.ts` (8,031 lines),
`ssh-browse`, `ssh-passphrase`, `ssh-relay-deploy`, `ssh-remote-cli-host-passthrough`,
`wsl-hook-relay-launch` and `user-data-path`.

`src/main/ssh/ssh-target-registry.ts` now holds that state plus its accessors.
`registerSshHandlers` populates it; the runtime reads it. The indirection is kept
deliberately: SSH providers register after construction and may reconnect, so
callers must resolve the current generation rather than freeze one.
`ipc/ssh.ts` re-exports all five, so non-test importers are unaffected.

`connectRegisteredSshTarget` still throws `ssh_handlers_not_registered` when no
handler layer registered — a headless host must fail loudly rather than report a
target as unreachable, which would read as `exited` (see ssh-execution-boundary.md).

Verified: 9 files / 59 tests across the ssh, automations and trust-preset suites;
orca-runtime.test.ts 1,183 pass; `pnpm typecheck` clean; `oxlint` clean.

* refactor(host): resolve the app root through the port in fork-reachable modules

`parcel-watcher-entry-path.ts` and `session-scanner-service-entry-path.ts` read the
app root via `require('electron').app` inside a try/catch that already returns null
when Electron is absent. They were therefore correct under plain Node at runtime and
only failed the *static* text check — which is real, not pedantic: the comment in
`ports/port-scan-command-client.ts:19` records that the plain-node-entry-guard fails
on that literal text, try/catch or not.

`hasAppEnvironment() ? getAppEnvironment() : null` gives the identical "no app root
here" answer without the text. That restores `hasAppEnvironment`, which an earlier
commit in this stack deleted as unused — it now has the caller it was waiting for.

Ratchet baseline 27 → 25.

Verified: 74 files / 458 tests; `pnpm typecheck` clean; `oxlint` clean.

* test(ssh): mock the SSH target registry alongside the ipc/ssh mock

Thirty-eight suites mocked `vi.mock('./ssh')` for `getActiveMultiplexer`. That
factory went inert when production started importing the accessor from
`../ssh/ssh-target-registry`, so the real module loaded and the assertions drifted.

Adds a companion registry mock returning the same stub, plus a
`sshTargetRegistryModuleMock` builder beside the existing `sshModuleMock` so the
shared harness stays one place. No assertion changed.

Found by a full-suite run: the targeted ssh/runtime suites were green while
30 tests in ipc/worktrees and ipc/repos were not.

* refactor(runtime): read app paths and the packaged flag through the port

`orca-runtime.ts` is the last module in its own graph that imports `electron`
directly. Nineteen of its uses were `app.getPath` (12) and `app.isPackaged` (7) —
exactly what the AppEnvironment port already covers.

Also removes a dead `const { app } = require('electron')` inside
`getOrchestrationDb`. It was left unused once the path came from the port, and it
is precisely the dynamic-require pattern `plain-node-entry-guard.ts` exists to
catch, sitting in the runtime's own constructor path.

What still binds `orca-runtime.ts` to Electron is now three sites, not nineteen:
`new Notification(...)` (one), `BrowserWindow.fromId` (one), and the
`ipcMain.on('terminal:tabCreateReply')` renderer round-trip — which is the browser
tab path, and the same one that would hang a headless host for ten seconds.

Two suites drove `electronMocks.app.isPackaged` directly; they now install a fake
AppEnvironment reading the same mutable field, so their per-test toggles work
unchanged and no assertion moved.

Verified: 376 files / 4,717 tests across src/main/runtime; typecheck and oxlint clean.

* test(serve): add the built-artifact terminal round-trip acceptance smoke

"The server started" proves almost nothing. Terminal creation dispatches into
OrcaRuntimeService, and without an installed headless PTY controller that path
falls through to a renderer reply that never arrives and times out after ten
seconds. A boot probe, a port bind, and a `host.platform` call all pass against a
server whose terminals are dead — which is exactly the gap the design doc's own
boot proof was retracted for.

This boots the BUILT `out/main/index.js --serve`, parses its ready payload, pairs a
real client over the advertised endpoint, lists worktrees, creates a terminal, runs
a command through the PTY, asserts the output comes back, and asserts clean
shutdown. It drives nothing but the public pairing + RPC surface, so the same
script is the acceptance gate a future Node-only backend must pass unchanged.

The sentinel invokes `process.execPath` rather than `echo`, because the shell
differs per platform and node does not.

Verified both directions: passes against the real server, and fails with an
actionable message when the command produces no output — a smoke that cannot fail
is worthless.

* fix(ssh): fail loudly when the multiplexer resolver was never installed

`getActiveMultiplexer` resolves through a resolver that `ipc/ssh.ts` installs at
module scope. A process that never loads the SSH layer — which is the whole point
of the Node-only backend — would get `undefined` from every call.

`undefined` already means something specific here: "not connected". So a missing
resolver and a disconnected target were indistinguishable, and a host with no SSH
layer would quietly report every target as not connected. That is the
unverifiable-reported-as-exited conflation `docs/reference/ssh-execution-boundary.md`
exists to prevent — the doc is explicit that absence of contact is never evidence
of absence of the thing.

A missing resolver is a wiring error, not a connection state, so it throws, matching
what `connectRegisteredSshTarget` already does for unregistered handlers.

Verified: 432 files / 4,759 tests across ipc, ssh, preflight, automations and trust
presets; typecheck and oxlint clean.

* refactor(pty): stop faking a BrowserWindow for the headless PTY path

`registerHeadlessPtyRuntime` passed `registerPtyHandlers` a stub object cast to
`BrowserWindow` whose `isDestroyed()` returned true and whose `webContents.send`
was a no-op — a window-shaped thing that lied about being a window, purely to
satisfy the type. Adversarial review named it as the same "looks fine, silently
returns a lie" pattern this codebase rejects elsewhere, and it is the shape that
keeps `electron` on a path that otherwise needs none.

`registerPtyHandlers` now takes `BrowserWindow | null`. An absent renderer is
semantically identical to a destroyed one — all 42 call sites already guarded on
`isDestroyed()` and skipped — so `src/main/ipc/pty-renderer-surface.ts` states that
directly: `isRendererGone`, `sendToRenderer`, `rendererWebContents`. The compound
`isDestroyed() || webContents.isDestroyed()` guards collapse into one predicate.

`isPtyWriteEventFromMainWindow` becomes null-tolerant and fails closed: with no
renderer no sender can legitimately match, so every write is rejected. Those
handlers cannot fire headless today, but failing closed is the right answer if that
ever changes.

This is the precondition for installing a PTY controller without Electron, which is
what a Node-only backend needs and what `terminal.create` actually calls.

Verified: 129 files / 2,473 tests across ipc/pty, providers and orca-runtime; the
built-artifact acceptance smoke still passes end-to-end (boot → pair →
terminal.create → sentinel → close), which is the check that matters most here
since this changes the headless PTY path itself; typecheck and oxlint clean.

* refactor(pty): read app paths and the packaged flag through the port

Follows the fake-window removal. `ipc/pty.ts` had nine `app.*` reads — all
`getPath`, `getVersion` or `isPackaged` — which the AppEnvironment port already
covers. The `BrowserWindow` import was also dead after the null-window change.

What still binds this file to Electron is now `ipcMain` (75 uses, all handler
registration) and `powerMonitor` (2). That is a clean statement of the remaining
job: split logic from registration, the same shape already applied to preflight
and the SSH registry.

Test wiring: the shared `pty-ipc-suite-environment` beforeEach installs a fake
AppEnvironment that reads through the existing `vi.mock('electron')` app object
rather than freezing values — suites toggle `app.isPackaged` mid-test to exercise
dev-mode spawn paths, so the port has to observe the same mutable field. One edit
in the shared harness covers every pty suite.

Verified: 128 files / 1,290 tests across ipc/pty and providers; the built-artifact
acceptance smoke passes; typecheck and oxlint clean; ratchet unchanged at 25.

* refactor(pty): inject the ipcMain surface so the PTY module loads without Electron

This closes the round-3 blocker: "the doc never says how orcad installs
setPtyController without Electron."

`registerPtyHandlers` owns the `RuntimePtyController` that `terminal.create`
actually spawns through — the thing a Node backend needs and cannot get from the
provider thunks. The module was otherwise host-agnostic already; the only thing
pinning 8,031 lines to Electron was a static `ipcMain` / `powerMonitor` import used
purely to register renderer handlers that no headless host will ever receive.

`src/main/ipc/pty-host-bindings.ts` makes those surfaces settable, defaulting to
no-ops. Unlike AppEnvironment and SecretStore, the default does NOT throw: a host
with no renderer legitimately has nothing to register against, so not registering
handlers nobody can call is correct rather than a hidden downgrade. The desktop
installs the real objects in `attach-main-window-services` before its handlers run.

Also converts the remaining electron import to a top-level `import type`. oxlint's
`no-import-type-side-effects` caught that inline `type` specifiers still leave a
side-effect import — precisely the "type-only is not enough if esbuild still emits
require('electron')" trap a reviewer flagged.

**`src/main/ipc/pty.ts` now bundles with zero `require("electron")`.** A Node entry
can call `registerPtyHandlers(null, runtime, …)` and get a working PTY controller.

Verified: 128 files / 1,290 tests across ipc/pty and providers; the built-artifact
acceptance smoke passes end-to-end — which is the check that matters, since this
changes how every PTY handler registers; typecheck and oxlint clean.

* fix(pty-bindings): drop two unused eslint-disable directives

CI runs oxlint with unused-disable reporting; the two
`@typescript-eslint/no-explicit-any` suppressions I added were never triggered by
any enabled rule, so they failed static analysis as dead directives. The `any[]`
rest args stay — they mirror electron's own IpcMain signature, and narrowing them
would reject the real object at the desktop call site.

Verified with the exact CI invocation: `oxlint --format github` reports 0 warnings,
0 errors across the repo.

* fix(pty): install the host bindings per process, not per window

A real regression my own change introduced, caught by the SSH docker E2E
(`paired-startup-exec-readiness` — "recovers startup exec through a headed paired
desktop owner"). It reproduced on rerun, so it was not a flake.

`setPtyHostBindings` was called inside `attachMainWindowServices`, i.e. when a
window attaches. But `registerHeadlessPtyRuntime` (index.ts:3163) calls
`registerPtyHandlers` on the serve path *before* any window exists — so those
handlers registered against the no-op default and never reached the real `ipcMain`.
A paired desktop owner then attached to a runtime whose PTY handlers were wired to
nothing.

The bindings describe the *host*, not the *window*: an Electron main process always
has `ipcMain`, whether or not a window is open. Installing them beside
`setAppEnvironment`/`setSecretStore` at the top of bootstrap fixes both paths.

Verified: 128 files / 1,290 tests; the built-artifact acceptance smoke passes;
typecheck clean; `oxlint --format github` (the exact CI invocation) reports 0/0.

* feat(orcad): de-electron the runtime core and add the Node entry + build gate

**`src/main/runtime/orca-runtime.ts` — 41,048 lines — no longer imports electron.**
Its last three sites go through `runtime-desktop-surface.ts`: a native notification,
the authoritative-window lookup, and the one `ipcMain` channel used by the
renderer-backed tab-create fallback. All three are unreachable without a renderer —
`createTerminal` already takes the background branch when no window exists (#10333) —
so a Node host installs none and the runtime relays notifications to paired clients,
which is the better destination anyway. Ratchet 25 → 24.

Adds `src/main/orcad/orcad-entry.ts`: Node host adapters plus a `startOrcad` that
constructs the runtime, installs the PTY controller via `registerPtyHandlers(null, …)`,
and serves RPC. It sets two defaults the constructor gets wrong for a headless host —
`canRecoverPersistentLocalPtys: false` (no daemon here) and
`getDesktopWindowStatus: 'blocked'` (a Node host can never be promoted to a desktop
window, which is what `'openable'` claims).

Adds `config/scripts/build-orcad.mjs`, which **currently fails, on purpose**: 25
modules still import electron (browser and speech clusters, plugins, jira/proxy,
filesystem-watcher, and four `require('electron').app` one-liners). It names them.

Two bugs found while building it, both worth recording:
- The first bundle looked clean and was not. `electron` was bundleable, so esbuild
  rewrote the metafile `path` to the resolved file under node_modules and a check for
  `path === 'electron'` passed while the package was in the bundle — it failed at
  runtime with electron's own installer message. The check now reads `original`, and
  electron is marked external so a residual import fails loudly instead.
- `jsonc-parser`'s UMD build breaks the bundle at load; aliased to its ESM entry, the
  same fix `build-relay.mjs` already carries.

Verified: desktop unchanged — the built-artifact acceptance smoke passes, runtime/pty/
provider suites green, typecheck clean, `oxlint --format github` 0/0.

* refactor(host): drop the last two require('electron') app lookups

`computer/sidecar-client.ts` and `ports/port-scan-command-client.ts` read the app
root through `require('electron').app` inside a try/catch. Both were already correct
under plain Node at runtime — they return null when it throws — but the literal text
fails the plain-Node entry guard regardless, which is why port-scan carried a comment
warning it must never become reachable from a fork entry.

Reading the AppEnvironment port gives the identical "no app root here" answer without
the text, so that warning is now obsolete and the comment says so.

Ratchet 24 → 22. Every remaining entry is a real coupling: the browser cluster (15,
which variant B does not ship), speech (2), plugins (2), and jira/proxy-settings (2,
needing an HttpClient port for Chromium session partitions).

Verified: 25 files / 209 tests; acceptance smoke passes; typecheck and
`oxlint --format github` clean.

* docs(orcad): record that the ratchet under-counts orcad's graph

The ratchet reports 22 electron importers; the orcad build reports 23. The extra is
agent-hooks/wsl-hook-relay-launch.ts, and the cause is a gap in the gate rather than
a rounding error: the ratchet measures what orca-runtime + runtime-rpc reach, while
orcad's entry also imports ipc/pty directly to install the PTY controller.

Once orcad ships it must become a ratchet entry point, or the two numbers drift and
the gate quietly stops covering the artifact it exists for.

* refactor(runtime): inject the browser commands factory

Drops 14 modules from the runtime's Electron graph in one change — the whole Chromium
browser cluster. Ratchet 22 → 8.

`OrcaRuntimeService` constructed `RuntimeBrowserCommands` as a field initializer, and
that construction is what pulled in `BrowserWindow`, `session`, `webContents` and the
cookie jars. Importing the class for its *type* is free; only building it costs.

So the class import becomes `import type`, and the instance comes from
`runtime-browser-commands-factory.ts`. The desktop installs the real factory at the
Electron entry. **All ~80 existing `this.browserCommands.*.bind(...)` delegations are
untouched** — a review round specifically warned that rewriting those was the
expensive, risky part, and this avoids it entirely.

With no factory installed, browser commands reject per call with `browser_unavailable`
rather than resolving to a stub that silently succeeds. The runtime already filters
browser capabilities out of `getStatus()` when no backend exists, so clients do not
offer the affordance in the first place.

Also corrects a stale comment in `pty-renderer-surface.ts` that still described the
fake window as present tense; it was deleted two commits ago.

Verified: 451 files / 5,513 tests across `src/main/browser` and `src/main/runtime` —
the entire browser automation suite; the built-artifact acceptance smoke passes;
`pnpm typecheck` and `oxlint --format github` clean.

* refactor(host): extract the plugin client list and port two app lookups

Ratchet 8 → 5.

- `listPluginsForClients` moves to `src/main/plugins/plugin-client-list.ts`. It needed
  only three `plugins/*` helpers, none of them Electron — it was colocated with
  `ipcMain.handle` registrations, so the runtime's `plugins.list` RPC dragged all of
  Electron in to call a function that reads a lockfile. Same shape as preflight.
  Dropping it also releases `ipc/plugin-marketplaces.ts`.
- `agent-hooks/wsl-hook-relay-launch.ts` and `speech/stt-service.ts` read `getAppPath`
  and `isPackaged` through the AppEnvironment port.

The five that remain are all genuinely Chromium and need the HttpClient port or a
watcher split, not another mechanical swap: `browser/cdp-bridge` (webContents),
`ipc/filesystem-watcher` (ipcMain), `jira/authenticated-request` and
`network/proxy-settings` (net + session partitions), `speech/model-manager`
(`net.request`, which honors app proxy settings that Node https does not — replacing
it is a behaviour change, not a rename).

Verified: 219 files / 1,922 tests across plugins, speech, agent-hooks and the runtime
RPC methods; the built-artifact acceptance smoke passes; typecheck and
`oxlint --format github` clean.

* refactor(network): resolve the default proxy session lazily

Ratchet 5 → 4.

`proxy-settings.ts` needed exactly one Electron value: `session.defaultSession`, as
the fallback when a caller does not pass `options.proxySession`. Callers could already
inject a session; only the default was hard-wired. It now comes from a settable
resolver, so the module loads under plain Node.

**A resolver rather than a Session, because a Session eagerly throws.** The first
attempt installed `session.defaultSession` directly in pre-ready bootstrap and broke
startup outright — `TypeError: Session can only be received when app is ready`. The
acceptance smoke caught it before commit. Deferring to first use is always after ready.

Behaviour with no session is not a degradation: there is no Chromium proxy config to
discover, so `resolveProxy` is skipped and the environment variables become the whole
answer rather than a fallback. Applying rules to a session that does not exist is
likewise skipped; settings are still honoured because outbound requests read the env.

This reaches past Jira — a review round noted `ensureElectronProxyFromEnvironment` is
also on the Claude HTTP path via `oauth-refresh.ts` and `rate-limits/claude-fetcher.ts`.

Verified: 48 files / 526 tests across network, jira and rate-limits; the
built-artifact acceptance smoke passes; typecheck and `oxlint --format github` clean.

* fix(index): merge the duplicate proxy-settings import

CI's code-quality lint (`oxlint --config config/oxlint-code-quality-native-plugins.json
--deny-warnings`) flags a module imported twice in one file. My earlier insertion added
a second `./network/proxy-settings` import beside the existing one.

Verified with CI's exact invocation: exit 0.

* refactor(network): add the HttpClient port and lift BrowserError out of cdp-bridge

Ratchet 4 → 2.

Two unrelated couplings, both of the same shape — a small thing living inside a
Chromium-heavy file.

`BrowserError` is a seven-line error class with no dependencies, but it lived in
`browser/cdp-bridge.ts`, which imports `webContents`. The runtime catches that type on
paths with nothing to do with CDP, so one import kept a Node host from loading the
runtime at all. Moved to `browser/browser-error.ts`; cdp-bridge re-exports it.

`jira/authenticated-request.ts` fetches through `net.fetch` and reads
`session.defaultSession`. `network/http-client.ts` makes both settable. This one is a
**named port rather than a silent fallback, because the fallback is not transparent**:
Electron's net follows Chromium session/proxy state, avoids undici's stale keep-alive
sockets after a VPN path change, and sends a Chrome user agent that Jira's XSRF check
depends on. A Node host gets `globalThis.fetch`, reads proxy config from the
environment, and sends Node's user agent. That difference is documented at the port.

`session.defaultSession` is read per call, not captured at install — it throws before
the app is ready, which is the mistake the previous commit made and the acceptance
smoke caught.

Test wiring: `jira/client.test.ts` installs the port *inside* `loadClientModule`, after
its `vi.resetModules()`, since the reset gives the module a fresh singleton.

Verified: 461 files / 5,616 tests across jira, browser, network and runtime; the
built-artifact acceptance smoke passes; typecheck, `oxlint --format github` and the
code-quality lint with `--deny-warnings` all clean.

* fix(http-client): register the Node fetch fallback with the call-site audit

`global-fetch-call-site-audit.test.ts` guards every global-fetch use, because the
global runs on undici where an unread response body can crash the whole process
(orca#8695). The HttpClient port's Node fallback is a new such call site and was
unregistered — the guard caught it in a full-suite run.

Registered with the reasoning, and the port's doc comment now states the body-safety
contract explicitly: it hands the Response straight to its caller and never inspects
it, so the consume/cancel obligation stays exactly where it already was — with the
caller, unchanged from when they called Electron's net directly.

Two comments elsewhere mentioned the global by name and tripped the line scan as false
positives; reworded to describe the behaviour rather than name the API.

Verified: audit passes; typecheck and `oxlint --format github` clean.

* fix(app-environment): read hasAppEnvironment through the realm slot
2026-08-22 21:34:39 -07:00
Neil 0bbc6c80e8 refactor(host): route app paths and version through an AppEnvironment port (#16019)
* refactor(host): route app paths and version through an AppEnvironment port

`app.getPath('userData')` is the single largest Electron coupling in the main
process — 37 call sites — and it is one of the things stopping the Orca runtime
from booting on plain Node. Give it the same treatment as SecretStore.

- `src/shared/app-environment.ts` — the port plus a settable registry, covering
  the members the runtime's module graph actually reads: paths, app path,
  version, packaged flag, shutdown hook, exit, and Chromium process metrics.
  `getAppEnvironment()` throws until installed, for the same reason the secret
  store does: a silent default resolves `userData` to the wrong directory and the
  caller writes real state there before anyone notices. No `node:` imports,
  because `src/shared/**` is in the web build graph.
- `src/main/host/electron-app-environment.ts` — the desktop adapter, a
  pass-through to `electron.app`.
- 9 modules migrated: telemetry, opencode/mimo/pi hook services,
  terminal-history-paths, terminal-scrollback-snapshots, cli-installer,
  clipboard-image-temp-file, memory/collector.

Deliberately NOT migrated: `src/main/browser/**`. That cluster is Chromium-
adjacent by nature — cookie jars, download destinations, offscreen pages — and a
Node backend does not ship it at all, so porting it buys nothing and churns
heavily-mocked suites. Also left alone for now: the call sites that additionally
touch `app.asar` path literals or `app.setName`, which need more than a
mechanical swap.

`getAppMetrics` stays on the port rather than being injected because
memory/collector.ts is its only caller and reads it from module scope; a Node
host returns [], having no Chromium processes to measure.

Test wiring: the secret-store setup file becomes `vitest-host-ports-setup.ts` and
installs both ports, exporting `fakeAppEnvironment`/`installFakeAppEnvironment`
so suites needing one specific member state only that instead of restating all
seven — which is boilerplate, and had pushed one suite past the max-lines budget.

Verified: 159 files / 1651 tests pass across every touched area; `tsc` clean on
both the node and web projects; `oxlint` clean.

* fix(typecheck): list the vitest host-ports setup in the node project

Three suites import `installFakeAppEnvironment` from config/scripts, but that
directory is outside tsconfig.node.json's include list, so composite typecheck
failed with TS6307. Listing the one file matches how this config already pins
individual files it needs.

Local `tsc --composite false` does not reproduce this — only `pnpm typecheck`
does, which is what CI runs.

* refactor(host): drop two unused AppEnvironment exports

hasAppEnvironment() and resetAppEnvironmentForTests() had zero callers. The
secret-store equivalents are used, so these were mirror-symmetry rather than
need; add them back when something actually needs them.

* test(terminal-history): install the AppEnvironment fake instead of mocking electron

These three suites mocked `electron.app.getPath` to point at a fixture dir. The
production module now reads the port, so the mock was inert and the global test
default's temp dir won — which broke the WSL path assertions and every deletion
count.

Found by a full-suite run, not by the targeted checks around the migrated modules,
which is the argument for running the whole suite on a refactor this wide.

* test(host-ports): remove the per-environment temp dir on teardown

The setup allocated a mkdtemp directory at module scope, which vitest evaluates
once per test *environment* — one per test file, not one per worker. Nothing
removed them, so a full 6,000-file run left thousands behind.

Proven: with an isolated TMPDIR, a three-file run previously added directories and
now leaves zero.

* fix(app-environment): anchor the installed environment to a realm global

Same reason as the SecretStore: vi.resetModules() rebuilds the module registry,
and an environment installed before the reset read back as uninstalled.

Brennan Benson 26bdfc0fe4 feat(agent-status): stamp observation provenance at every status ingress (STA-4293) (#14706)
Add an optional `observation` facet to agent status rows recording the origin
(hook | osc | title | process | launch | orchestration), the authority that
sequenced it, a per-pane incarnation, a monotonic revision, and the authority's
own clock. Stamp it at every ingress; no consumer reads it.

Boundary is stamped from the hook listener's existing per-provider
`isNewTurnEvent`, not a second list of event-name literals. Identity-only
(`providerSessionOnly`) rows are tagged `kind: 'identity-only'` so future
consumers do not each rediscover that they are not turn transitions.

The staleness-decay contract is documented at the type: staleness must be
computed against the same authority clock that stamped `observedAt`, or
replicas must decay on local receipt time. Not fixed here.

Behavior-neutral: optional field on existing JSON, never persisted, never
published to paired clients, and never inherited across writes.

that feeds both pipelines into a real StatsCollector.

Switches StatsCollector off AgentDetector and onto the canonical agent-hook

- main/index.ts subscribes the recorder to subscribeEnrichedStatus and
  subscribePaneStatusClear, next to where StatsCollector is constructed.
- orca-runtime.ts no longer feeds raw PTY bytes to a stats detector.
- StatsCollector keys sessions on a stable pane key, not a per-spawn ptyId.

* feat(crash-reporting): read-only Windows install-dir DACL probe

Records whether the install tree carries an orphan S-1-15-2-* package ACE
with no S-1-15-2-1/-2 to satisfy it — the state that reproduces the
0x80000003 GPU/renderer init crash 10/10 (electron/electron#51761).

Diagnostic only: never writes an ACL, never changes behavior.

* fix(crash-reporting): evaluate the ACL signature per target and flag locale risk

Three readiness-review findings:
- the signature was merged across targets, so a grant on the directory masked
  its absence on the module file - the exact per-file state the probe exists
  to detect
- the well-known package name check is English-only and icacls localizes it,
  so a non-English box could false-positive silently; report whether the
  check could be trusted
- the serve-mode test omitted platform, so the gate was never exercised

Also switch to the durable recorder (this runs after initObservability, so the
span lands in the diagnostics bundle) and correct two comments that misstated
where the probe runs.

Neil 24e662adc1 feat(ssh): verify host keys, and restore panes correctly across a reconnect (#14844)
* docs(ssh): design for real host key verification (STA-4319)

Today's ssh2 verifier records a fingerprint and returns true — every host key is
accepted, with no known_hosts consult and no change detection anywhere in
src/main/ssh/. Scope is per-connection, so exec, SFTP, port forwarding, the
watcher and relay deploy all ride that one unverified handshake, and the
ProxyJump path puts the final hop — the topology most likely to cross untrusted
network — on ssh2 specifically.

Decisions worth calling out:

- Read the user's known_hosts as a trust source but NEVER write to it. That file
  is shared with every other SSH tool on the machine; appending means line
  endings, permissions, concurrent writers and a corruption blast radius well
  beyond us. Accepted keys go to our own per-target store. Reading theirs is also
  the entire migration story: most developers already have their hosts there.
- Mismatch is scoped to the SAME key type. A host with only an RSA entry that
  presents ed25519 is unknown, not changed. ssh2 negotiates ed25519 first, so
  without this we would fire a change-of-key alarm at nearly every existing user
  on their first upgraded connect — training them to dismiss the one warning that
  is supposed to mean something. Flagged in review as the decision I am least
  sure of; a downgrade-vector argument against it is being tested.
- Changed key hard-fails with no override button; recovery is a separate explicit
  action, offered only when OUR store is what disagreed, because forgetting our
  record cannot unblock a known_hosts conflict.
- Background reconnects deny rather than prompt. A dialog the user cannot place
  in context only teaches click-through.

Two traps are documented because either would make the fix silently do nothing:
an async verifier returns a Promise, which ssh2 reads as truthy and accepts
immediately; and the existing test mock invokes hostVerifier with one argument
and ignores the return, so it would pass against a verifier that never decides.

Design only — no behaviour change. The doc is added to the tracked-reference
allowlist in .gitignore alongside the other docs/reference entries.

* docs(ssh): revise the host key design after security and migration review

Three things the reviews changed, kept visible rather than quietly edited out.

THREAT MODEL WAS WRONG IN THREE PLACES. Jump hosts are not the worst case — they
are already safe: shouldUseSystemSshTransport branches on exactly the inputs
resolveEffectiveProxy does, and attemptConnect returns after the system probe, so
ProxyJump goes through OpenSSH and is verified. Agent forwarding was overstated
(gated on the user's ForwardAgent). Credential theft was understated: any auth
error counts as agent fallback, so a MITM walks the user to the password AND
private-key passphrase prompts, and cachedPassword replays without prompting. The
relay claim was backwards — the attacker owns their own machine; the real impact
is the return direction, where they become the host our workspace trusts.

TYPE SCOPING IS A DOWNGRADE VECTOR WITHOUT ALGORITHM ORDERING. This was the
decision I flagged as least certain and asked to have argued both ways. OpenSSH
is safe only because order_hostkeyalgs() puts known types first and RFC 4253
gives the client's order priority. ssh2 negotiates ed25519 first regardless, so
an attacker who cannot forge the RSA key on file just presents ed25519 and gets a
friendly first-contact prompt instead of a hard failure. Keep scoping, but set
algorithms.serverHostKey to lead with the types on file — and add a sixth
outcome for 'unknown type, known host', which must never read as first contact.

SHIP THE DEFENCE BEFORE THE DIALOG. Startup restore fires eager connects for all
targets in parallel with a 15s timeout while a prompt would live 120s; ephemeral
VM targets present a new key every launch; paired-web connects run on the host
desktop, so the dialog opens on someone else's screen. Phase 1 is therefore no
modal at all: consult known_hosts and our store, match connects, unknown persists
with accept-new semantics, mismatch and revoked hard-fail. That is the whole MITM
defence with none of the migration risk.

Also folded in, verified live against OpenSSH 10.2p1: the without-port fallback
(bracketed lookup first, then bare, where the second pass can only yield match or
unknown — otherwise a bare line plus a non-default port produces a spurious
prompt); hashed entries hash the candidate form; multiple files union; a
cert-authority line does not match a plain key. IPv6 and bracket parsing moved
INTO scope — that is a parser requirement, not a scope call, and getting it wrong
produces the prompt-training harm the design exists to avoid.

* feat(ssh): parse and match OpenSSH known_hosts

The matcher half of STA-4319. No behaviour change yet — nothing calls this.

Hand-rolled because no maintained JS implementation exists, and written against
behaviour observed from OpenSSH 10.2p1 rather than inferred from the man page.
Three of those behaviours a reasonable reading gets wrong:

- A non-default port is TWO ordered lookups, not one candidate set: '[host]:port'
  first, then bare host ('checking without port identifier' in ssh -v). The
  fallback pass can only yield match or unknown — OpenSSH downgrades a wrong key
  there rather than reporting a change. Collapse them and anyone holding a bare
  line who connects off-port gets a spurious first-contact result; treat the
  fallback as authoritative and they get a false change-of-key alarm.
- Revocation resolves in its own pass so the verdict cannot depend on line order.
  Verified both orderings.
- A cert-authority line never matches a plain host key; it only validates
  certificates. A normal line alongside it still decides.

Mismatch is scoped to the same key type, and a host known by a DIFFERENT type
returns unknown-type-known-host rather than plain unknown — an attacker who
cannot forge the key on file must not get a friendly first-contact result by
presenting another type. That outcome is only half the defence; the other half
(leading serverHostKey with known types) lands with the wiring.

47 tests from vectors executed against real sshd, including ssh-keygen -H hashed
entries. Each of six mutations reddens it: collapsing the passes, letting the
fallback report mismatch, dropping type scoping, resolving revocation in line
order, honouring an unrecognised marker, and skipping the blob/type agreement
check.

* feat(ssh): decide what to do with a presented host key

The policy half of STA-4319, kept separate from the ssh2 wiring so it is testable
without a handshake and injected rather than importing its sources, so a test
states its own trust state instead of writing files.

Phase 1 ships no dialog — a test asserts the decision is never 'prompt'. Startup
restore opens every previously-active target at once, ephemeral VM targets would
ask every launch, and paired-web connects run on the host desktop where the
dialog would appear on someone else's screen.

Ordering that matters: revocation outranks everything including
StrictHostKeyChecking=no, because a revoked key is a statement that this key is
known-bad rather than merely unrecognised. known_hosts is named before our own
store on a change, because its remedy (ssh-keygen -R) is the one that also
unblocks ssh and git — pointing at a remedy that cannot work is worse than none.

Two carve-outs with reasons: an ephemeral runtime target accepts WITHOUT
recording, since a fresh VM presents a new key every launch and a stored record
would accumulate per launch and eventually read as a spurious change; and when
ssh -G ran on the HOME-divergent path that suppresses /etc/ssh/ssh_config, an
unknown host is denied, because a site-wide policy may forbid it and being laxer
than ssh is the one outcome that is never acceptable.

Rejection text deliberately avoids 'authentication failed' and 'permission
denied': the reconnect ladder classifies on those substrings, so a denial phrased
that way is retried forever against a decision that will never change. Pinned by
a test.

* feat(ssh): build the host key verifier and the algorithm order that makes it safe

Still not wired into the handshake — that lands next. This is the piece that
turns a decision into an ssh2 callback, plus the half of the design that is easy
to forget because it lives in a different config field.

The verifier MUST be a plain function returning undefined. ssh2 does
'const ret = verifier(key, verify); if (ret !== undefined) verify(ret)', so an
async function returns a Promise — neither undefined nor falsy — and ssh2 accepts
the key immediately while ignoring whatever the callback later decides. Making
this async would silently restore exactly the accept-everything behaviour the
module exists to remove, so a test asserts the return value is undefined.

orderServerHostKeyAlgorithms is what makes type-scoped matching safe rather than
a downgrade. RFC 4253 gives the client's algorithm order priority, so leading
with the types we already hold for a host denies a server the choice of
presenting some other type to convert a hard failure into first contact. Without
it, an attacker who cannot forge the key on file just offers a different
algorithm. Revoked entries never contribute to that order.

Also fails closed on two paths that would otherwise hang or over-trust: a key
whose own length-prefixed header cannot be read is refused rather than reasoned
about, and a throw from any dependency denies, because ssh2 may not catch an
exception raised inside the verifier and the handshake would hang instead of
failing.

18 tests. Includes the two negative cases that matter — first-contact keys are
recorded, but keys we already know, rejected keys, ephemeral runtime targets and
a lax StrictHostKeyChecking are not.

* fix(ssh): promote every RSA signature algorithm for a known ssh-rsa key

A known_hosts entry names the KEY type, which is not the negotiated ALGORITHM
name. One ssh-rsa key is offered as rsa-sha2-512, rsa-sha2-256 or ssh-rsa
depending on the signature algorithm, so matching the literal name only would
leave a host we know by RSA ordered behind ed25519 — precisely the ordering this
function exists to prevent, and precisely the population (RSA-era known_hosts
entries) it was written for.

Verified from ssh2's own negotiation while wiring this: kex.js iterates the
CLIENT list and takes the first entry the server also offers, so client order
does decide, as RFC 4253 says. ssh2's default order leads with ed25519 and places
the RSA algorithms fifth through seventh.

* fix(ssh): verify host keys instead of accepting every one (STA-4319)

The actual fix. ssh-connection's verifier recorded a fingerprint and returned
true, so every ssh2 connection accepted every host key — no known_hosts consult,
no change detection. It now consults the user's known_hosts plus our own store
and refuses a changed, revoked or unverifiable key.

Phase 1 by design: no dialog. Unknown hosts are accepted and recorded
(accept-new semantics), because startup restore opens every previously-active
target at once, ephemeral VM targets present a new key each launch, and
paired-web connects run on the host desktop where a prompt would appear on
someone else's screen. The MITM defence lands now; the prompt is Phase 2.

Also sets algorithms.serverHostKey to lead with the types already known for the
host. Without it the type-scoped matching is a downgrade — an attacker who cannot
forge the key on file just presents another type and turns a hard failure into
first contact. Verified from ssh2's kex.js that the client list decides.

Denial replaces ssh2's generic handshake error with the specific reason, because
the reconnect ladder cannot distinguish a generic failure from a transient fault
and would retry forever against a decision that will never change.

An unreadable trust store degrades to known_hosts only rather than failing the
connect: a changed key is still refused, and a host trusted only by us falls back
to first contact and is re-recorded, reaching the same decision.

The ssh2 mock now uses the callback form and aborts the handshake on denial. As
written it called hostVerifier(key) with one argument and ignored the result, so
it would have passed against a verifier that never decides — flagged in the
design as a mock that had to change, not a test to quietly rewrite. Two new tests
pin the wiring rather than the module: an unidentifiable blob is refused, and a
well-formed key is accepted.

Note for review: commit 2d2a0880ba unintentionally swept in two modules built
concurrently (ssh-known-hosts-source, ssh-host-key-store) because I staged with
'git add -A'; its message describes only the verifier. Both are covered by their
own tests, but the attribution in that commit is wrong.

1461 SSH tests pass.

* fix(ssh): bind the host key store to the active profile at startup

Without this the store reports nothing trusted on every launch. Safe — known_hosts
still decides, and a host trusted only by us degrades to first contact and is
re-recorded — but it silently discarded our own accept records, so the store the
design calls for was not actually in use.

Bound beside the profile Store, since it is a sidecar of the same data file.

Also records why the paired-web carve-out the migration review asked for is NOT
implemented in Phase 1, rather than leaving it looking forgotten. That carve-out
exists to stop a web client waiting out the 120s prompt timeout — a hang only
reachable if a prompt exists, and Phase 1 has none, which the decision function
pins with a test asserting it never returns 'prompt'. An RPC connect therefore
behaves exactly like a local one. Adding a fail-fast path now would introduce a
failure mode for a hang that cannot occur; it becomes load-bearing when the
dialog lands and is listed under Phase 2.

Noted there for whoever builds Phase 2: runtime/rpc/methods/ssh.ts already
swallows the specific error and rethrows a generic one, so the host-key reason
will not reach a web user without a change there too.

Full unit suite: 52,352 pass. The 8 failures are the known environment baseline
(5 osc8, 2 IME) plus one browser-cookie suite-ordering flake that passes in
isolation — none in src/main/ssh, and none related to this change.

* fix(ssh): close two downgrades the implementation review found

Both were in my wiring, not the design, and two reviewers found the first
independently.

1. OUR STORE WAS TYPE-DOWNGRADABLE. The inline lookup filtered by key type first
and could only answer match/mismatch/unknown, so a record of a DIFFERENT type for
the same endpoint read as "unknown". A host learned on first contact — ed25519,
since ssh2 proposes it first — and absent from known_hosts could then be
impersonated by presenting RSA: both sources say unknown, so accept-and-remember,
silently. That is exactly the downgrade D3 says the design cannot ship without,
applied to the records we create ourselves. The store's own isTrusted already
computed the right answer and had no production caller. Stored types now also
feed the algorithm ordering, without which the guard is only half present.

2. WE KEYED ON THE ORCA LABEL, NOT THE DIALED HOST. "ssh -G" echoes its own
argument back as its hostname field when no Host block matches, so for a manual
target that field IS the Orca label — the one name D2 forbids keying on, and one
ssh never wrote. We consulted no entries at all, so an impersonated host read as
first contact. Now keys on the dialed host, which buildConnectConfig has already
resolved through HostName, with HostKeyAlias still winning.

That inverted an existing test rather than deleting it: "uses the resolved
hostname, never the Orca label" encoded an assumption disproved against OpenSSH
10.2p1, so it is renamed and reversed with the reason recorded in the test.

3. NO READABLE SOURCE IS NOT FIRST CONTACT. Every known_hosts file failing to
read was indistinguishable from "this host is unknown", so a changed key would be
accepted the one time we could not check. The loader now reports how many files
it could read, and zero readable sources with an empty store takes the strict
path instead of recording trust.

4. A superseded attempt's rejection could replace the live attempt's error, and
substituting a new Error drops ssh2's code, so a transient ECONNRESET would stop
being classified as retryable. The rejection is now local to its attempt.

5. displayHost was the Orca label, so a mismatch could print
"ssh-keygen -R <label>" — a remedy that removes nothing.

Also adds the tests that would have caught 1 and 2, the stale-attempt denial, and
IPv6 literals, which the design moved into scope and nothing covered.

1,469 SSH tests pass.

* fix(ssh): stop offering credentials to a host we just refused

A refused host key ended the handshake and then fell into the credential
ladder, because ssh2 reports a denied key as a generic auth failure and the
passphrase branch is eligible on message shape alone whenever an encrypted
identity file is configured. So the sequence was: decide this host may not be
who it claims to be, then ask the user for their passphrase and hand it to it.
Failing that, prompt for a password. Failing that, retry over the system ssh
binary, which for a disagreement with our own store rather than known_hosts
would simply connect.

That inverts the point of checking at all. A denied key is now final for the
attempt: recognised by type before any fallback runs, and again inside the
agent-fallback retry, which re-runs the handshake and so can be the attempt that
denies.

Two things had to change for that to hold.

The rejection is now a HostKeyVerificationError rather than a rebuilt Error, so
the connect path recognises it by type. Substring matching would have worked
today and quietly stopped working the first time a reason string was reworded —
and these strings are already worded around the auth-error classifier, so they
are exactly the kind that get edited.

And the verifier now reports the denials that skipped the policy: an
unreadable key blob and an internal failure both denied without calling
onDecision, so the connect path saw only ssh2's generic failure and walked the
ladder. That was the actual path the new test hit first. The report carries no
fingerprint, since there is no host key to identify, and the connection no
longer overwrites the fingerprint it holds with an empty one — the relay keys
install-lock isolation on that value.

The reconnect ladder also refuses to retry it. Its classifier is otherwise
substring-driven, so a reason containing "connection reset" would have been
retried until the ladder gave up, burying the reason under nine attempts.

Tests: no credential prompt after a refusal, an encrypted key configured so the
passphrase branch is eligible; refused reports as 'error', not 'auth-failed',
which would invite the user to re-enter credentials that are not the problem;
no retry; both bypassing denials report; a throwing listener still denies rather
than hanging the handshake.

Also drops three test files a bisect resurrected from before the revert that
deleted them.

172 tests pass across the three touched files; typecheck and lint clean.
Pre-existing on origin/main and untouched here: 3 failures in
ssh-connection-sftp-namespace.test.ts.

* fix(ssh): stop treating an absent known_hosts as a source we failed to read

The previous commit's "no readable source is not first contact" guard was right
about the danger and wrong about how to detect it, and the version that shipped
would have refused every connection a new profile ever makes.

A file that does not exist and a file that refuses to open both arrive as a
rejected readFile, and I counted them the same way. They are opposites. An
absent known_hosts is the normal state — ssh creates it on its own first connect,
and an Orca profile that has never connected has none — and it is real evidence
that no host is known. A file that exists and will not open is evidence withheld:
the entry that would have said "this key changed" may be sitting in it.

The default list is the reason this was fatal rather than obscure. It always
names known_hosts2, which essentially never exists, so on a machine with a normal
known_hosts the count was 1-of-2 and everything worked; on a fresh profile it was
0-of-2 and every connect failed with "the system SSH configuration could not be
read" — a message about a file the user does not have and an error they cannot
act on. The suite passed only because the machine running it happens to have a
known_hosts. Pointing HOME at an empty directory fails 62 connection tests, which
is what the new wiring test does.

So the count is now unreadableFileCount: files that exist and could not be read,
which is the condition the guard was always trying to express. Any one of them
takes the strict path; an absent or empty file takes none. The store clause is
gone with it — a store hit already returns accept before this is consulted, so it
never changed an outcome.

Tests: absent, empty, permission-denied, directory, and all-parsed at the source;
first contact with no known_hosts at all at the wiring level.

1,482 SSH tests pass. The 3 failures in ssh-connection-sftp-namespace.test.ts are
pre-existing on origin/main and untouched here.

* fix(ssh): let an ephemeral runtime outrank sources we could not read

Three things, all about the same question: when we cannot see everything that
decides a host key, what does that actually license us to refuse?

1. ON-DEMAND RUNTIMES WERE REFUSED FOR A POLICY THEY COULD NEVER SATISFY.

A machine provisioned a minute ago cannot be in known_hosts, by construction —
which is why it has a carve-out at all. But the carve-out sat BELOW the
incomplete-sources check, so anyone whose HOME diverges from their passwd home
(sandboxes, our own E2E isolation) took the `-F` path, and every on-demand
runtime connection was refused, pointing at a config file the user cannot fix.

Refusing there buys nothing. No policy, seen or unseen, is satisfiable by a host
that did not exist yesterday; the trust comes from the provisioning channel. So
the carve-out now outranks it. An EXPLICIT StrictHostKeyChecking=yes still wins
over both — that one we can read, and the user asked for it.

2. THE FLAG WAS NAMED FOR ONE OF ITS TWO MEANINGS.

`siteConfigSuppressed` started as "-F hid /etc/ssh/ssh_config" and had since
grown "a known_hosts file exists and would not open" — which is not a site
config, and reading the name in the decision function told you nothing about
why an unreadable file landed there. It is `verificationSourcesIncomplete` now:
we could not see something that decides this, so do not extend NEW trust. A host
we already know still connects, because a match is decided before this is
reached, and that is now pinned by name.

3. THE COPIED ssh2 ALGORITHM LIST HAD NO DRIFT ALARM.

We reorder ssh2's default host-key proposal, which meant hand-copying a list
ssh2 exports only from a deep internal path. ssh2 throws `Unsupported algorithm`
on anything outside its supported list, so drift does not degrade — every
target stops connecting, before a socket opens, with a message about an
algorithm the user never chose. Worth knowing that the list is also built
conditionally on ed25519 support.

Kept as a literal rather than a deep import, since silently adopting a new
proposal order is the wrong default — the order is what makes type-scoped
matching safe, so a change deserves review. A test now compares it against
ssh2's real constant and checks every entry is one ssh2 accepts. Moved next to
the ordering function it feeds, and out from between the import statements.

1,488 SSH tests pass. The 3 in ssh-connection-sftp-namespace.test.ts are
pre-existing on origin/main.

* docs(ssh): record what review changed and the STA-4319 follow-ups

The design survived implementation; every defect found afterwards was in the
wiring. Worth recording the pattern, because it repeated five times: each one
made us either blind or unusable, never subtly wrong — and four of the five
broke legitimate hosts rather than admitting bad ones.

Action items separate the things Phase 2 must decide (UpdateHostKeys, which is
now the likeliest way a legitimate user meets a rejection; the web client never
seeing the reason; RPC fail-fast) from the gaps Phase 1 knowingly accepts (WSL,
CheckHostIP, ca-only hosts, the hand-copied ssh2 algorithm list).

Also flags the rollout risk plainly: this is the first release in which Orca can
refuse an SSH connection at all.

* test(ssh): pin the ephemeral carve-out where it is actually observable

The first version of this test asserted an on-demand runtime connects on first
contact, which every target does — it would have passed with the carve-out
deleted. Pointing HOME at a home whose known_hosts exists and will not open makes
the two cases diverge: a normal target is refused there, an on-demand runtime is
not. Removing the carve-out now fails three tests instead of none.

Also covers the wiring for the unreadable-source refusal itself, which until now
was only pinned at the decision level.

* test(ssh): pin the parser against real ssh -G output, and accept-new against ask

Two gaps the audit named.

The ssh -G fixtures were all hand-written, which means they encode what I expect
ssh to print. This one is verbatim OpenSSH_10.2p1 output for a Host block using
HostName, HostKeyAlias, StrictHostKeyChecking accept-new, two UserKnownHostsFile
paths and a non-default port. The format detail that matters: each file list
arrives space-separated on ONE line, so reading it as a single path would consult
nothing for anyone with more than one file configured.

And accept-new was untested despite being a real OpenSSH value. It currently
behaves identically to ask, which is exactly right while no dialog exists and is
what lets the defence ship without a modal — so the equivalence is now pinned,
and Phase 2 has to break it deliberately rather than discover it. Plus a guard
that accept-new never falls into the strict branch.

* test(ssh): cover the wire from an accepted key to a record on disk

Nothing covered the store end to end. Every connection test runs with it
unwired — a real path, since it degrades to known_hosts only — so an accepted
first-contact key was never observed becoming a record, and the record was never
observed being believed on the next connection. Without that wire the store is
dead weight: an unknown host connects every time and is never learned.

Its own file for two reasons. initSshHostKeyStoreFile binds module-level state
for the rest of the process, and binding it makes the connect prelude do real
disk I/O — which the shared suite cannot absorb, because its reconnect tests
drive the clock with fake timers and an fs round trip does not complete inside an
advanced tick. Adding these there turned 12 unrelated tests red.

Covers: the record is written; it is read back as a match; the same key is not
recorded twice; a DIFFERENT key for a host we recorded ourselves is refused
(the store's entire security value, and a case known_hosts cannot catch since it
has never heard of the host); and an on-demand runtime records nothing.

Stubbing rememberHostKey to a no-op fails four of the five.

* fix(settings): stop truncating the SSH connection error to one line

The host key messages are written to be actionable — a mismatch ends in
"Run: ssh-keygen -R <host>", which is the remedy that also unblocks ssh and git.
The only place in the renderer that displays an SSH connection error clamped it
to a single line with `truncate` and carried no title attribute, so the remedy
was unreachable, not even on hover. The careful wording reached a CSS ellipsis.

Wraps instead, with [overflow-wrap:anywhere] because a long hostname offers no
break opportunity and would overflow the column on its own. The paragraph only
renders on failure, so the extra height costs nothing in the normal case.

CORRECTION to the four preceding commits: they each claimed 3 pre-existing
failures in ssh-connection-sftp-namespace.test.ts. That was my error — I had been
running `npx vitest` without `--config config/vitest.config.ts`, so the project's
setupFiles and execArgv were absent. Under the real config those 3 pass, and have
throughout. The whole SSH suite is green: 1,504 passed, 13 skipped.

Still failing on this branch and unrelated to it (different subsystems, no file
overlap): 5 in terminal-snapshot-osc8-roundtrip and 2 in browser-cookie-import.

* fix(terminal): show why the SSH connection failed, not just that it did

The reconnect overlay took only a status, so every failure rendered the same
sentence: "The SSH connection to devbox failed. Connect again to continue this
terminal session." A refused host key and a network timeout were indistinguishable
there, and the host key message — the only place that names the remedy, down to
`ssh-keygen -R <host>` — reached no terminal user at all. The state carried it the
whole way; the overlay simply never asked for it.

Adds it as a second line rather than replacing the sentence. The sentence says
what to do, the detail says what happened, and keeping both means an errno
failure does not lose its guidance to make room for "connect ETIMEDOUT". Wrapped,
for the same reason as the settings card: the remedy is at the end.

Suppressed for a removed target, which already explains itself and can never
reconnect — a stale connection error underneath would contradict it.

The new selector mirrors selectRuntimeAwareSshStatus branch for branch, including
the unreachable-environment and un-hydrated-bucket nulls, so the pair cannot
disagree about which source they read and a detail is never shown next to a status
it did not come from.

Known and NOT addressed here: "Connect again" is still the wrong advice for a
decision that will never change. Telling those apart needs a typed reason on the
wire rather than a string, which is a remote-wire-compatibility decision; it is
recorded in the STA-4319 follow-ups.

Pre-existing on this branch and untouched: 2 failures in
terminal-ime-xterm-resumed-preedit-visibility.

* docs(ssh): record where the rejection message actually lands

Traced end to end, because a rejection the user cannot read is a half-shipped
feature — and two of the surfaces were dropping it entirely, both now fixed.

What is left is written down rather than guessed at: the status bar renders only
'Error', the terminal overlay's call to action still invites a retry that cannot
succeed, toasts carry Electron's remote-method prefix, and the paired-web path
replaces the text with 'SSH connection unavailable' on every route — which also
affects a DESKTOP user viewing a host owned by a remote Orca server, not just web
clients.

* refactor(ssh): give the store one matcher instead of two

The connect path had its own copy of the store comparison, because ssh2's
verifier decides synchronously and cannot await the file, so records are
preloaded. That copy is precisely where the type downgrade came from: it answered
only match/mismatch/unknown, so a record of a different type for the same
endpoint read as first contact and a host learned on first contact could be
impersonated by presenting another key type. Fixing it left two implementations
that have to agree forever, which is the same bug waiting to happen.

matchTrustedHostKeys is now the single pure matcher; isTrusted is a load plus a
call to it, and the connect path calls it directly on preloaded records. Same for
the key types that feed the algorithm ordering, which the connect path was also
filtering by hand.

The two copies had in fact already drifted: the connect path lower-cased the
query host where the write trims AND lower-cases. Not reachable today — the host
is trimmed before it reaches there, which I confirmed by mutating the
normalisation and watching the wiring test pass anyway. So this is not a bug fix,
and the wiring-level test I first wrote for it proved nothing and is gone. The
unit test that replaces it drives the matcher directly, where the input is mine
to control, and it does fail when the normalisation diverges.

Also adds an equivalence test across all six outcomes between the preloaded and
awaited paths, so the two can never answer differently again.

Restores the local name siteConfigSuppressed for the `-F` check; it was renamed
along with the decision input, but at that site it really does mean only the one
thing, and the union with the unreadable-file count happens one line later.

1,509 SSH tests pass.

* test(ssh): check the matcher against a live OpenSSH client, not against my beliefs

Every other test in the parser file states what I believe ssh does. These state
what it did: an OpenSSH 10.2p1 client against a real sshd on 127.0.0.1:2222, with
the client's own verdict recorded from its output, and ssh-keygen -H's own salt
and hash pinned as a vector.

Two assumptions the design leans on were worth more than an argument.

THE FALLBACK PASS MAY NOT REPORT A CHANGE. We look up `[host]:port` first and
retry the bare host, and only the first pass may answer `mismatch`. With
StrictHostKeyChecking=accept-new, a bare line holding a DIFFERENT key, dialed on
2222, ssh connected and appended a new `[127.0.0.1]:2222` line — no
IDENTIFICATION HAS CHANGED banner. It read that as first contact. Had we reported
a change there we would refuse hosts ssh connects to happily, and the wrongness
would have been invisible: refusing looks like the cautious choice.

AND THE TYPE-SCOPING REJECTION IS NOT AN INVENTION. known_hosts holding an ssh-rsa
key while the server offers ed25519 makes ssh print IDENTIFICATION HAS CHANGED and
refuse. So unknown-type-known-host is neither stricter nor laxer than ssh —
treating it as first contact, which is what a naive type-scoped lookup does, is
the laxer mistake.

That second result also fixes the message. ssh is blocked too, so
`ssh-keygen -R <host>` is the remedy that unblocks both, and we were naming it
only for a same-type mismatch — leaving this case with a diagnosis and no way
out. Named now when known_hosts is the source that disagrees, and still not named
when it is our own store, which ssh-keygen would not touch.

1,516 SSH tests pass.

* docs(ssh): record the two assumptions a live client confirmed

Both were load-bearing and neither was obvious: the bare-host fallback pass may
not report a change, and unknown-type-known-host is what ssh itself does rather
than something we invented. Getting the first backwards would have refused hosts
ssh connects to happily, which is the failure mode that looks like caution.

* style(ssh): satisfy the code-quality lints in the two new test files

A string concatenation that should be a template literal, and an inline
import() type annotation that should be a type-only namespace import — erased
before vi.mock's hoisted factory runs, so the mock is unaffected.

pnpm lint is clean.

* fix(ssh): honour StrictHostKeyChecking, which had never once been read correctly

`ssh -G` does not echo the value the user wrote. StrictHostKeyChecking is
rendered through fmt_multistate_int, which prints the first entry of
multistate_strict_hostkey, and that table lists true/false before yes/no:

  yes -> true | no -> false | off -> false | accept-new -> accept-new | ask -> ask

Verified against OpenSSH 10.2p1 from both a config file and -o. Not
10.2-specific; the table ordering is old.

The decision function tested only 'yes'/'always' and 'no'/'off' — spellings that
cannot arrive. So `StrictHostKeyChecking yes` fell through to the default branch
and we accepted AND PERSISTED a host the user's config explicitly says to refuse.
That is the worst outcome this feature can produce, and it was the behaviour for
every strict user from the first commit. `no`/`off` landed there too, breaking
the documented "lax settings never persist" invariant.

Every unit test passed throughout, because they fed the function 'yes' — the
value a human writes, not the one that reaches the code. My ssh -G parity test
did capture real output, but I happened to configure accept-new, one of only two
values that round-trip unchanged. The new table is keyed on configured value ->
what ssh -G actually prints, and asserts both reach the same verdict, so the
question "is this the spelling that arrives?" cannot be assumed again.

Found by a parity review against a live OpenSSH client.

* fix(ssh): stop the fallback pass accepting a changed key, and refusing a new one

One wrong loop scope, two opposite errors, both reproduced against a live
OpenSSH 10.2p1 client and an ed25519-only sshd on 127.0.0.1:2223.

ACCEPTING A CHANGED KEY. ssh runs the bare-host fallback only when the
port-qualified lookup matched no plain entry of ANY key type. We ran it unless
pass 0 produced a match or a SAME-TYPE mismatch. So with an off-port RSA entry
plus a bare, correct ed25519 line — an ordinary shape, an old off-port entry
beside one written by a port-22 connect — ssh printed IDENTIFICATION HAS CHANGED
and refused, with no "checking without port identifier" in -v because the
fallback never ran, while we reached the bare line and returned `match`.

REFUSING A NEW ONE. sawKnownHostOtherType and sawCertAuthority were declared
outside the pass loop, so an entry found only on the fallback pass could set
them. A bare ssh-rsa entry, dialed on a non-default port against an ed25519-only
server, made ssh add the host and connect — plain first contact — where we
returned unknown-type-known-host and hard-failed. That is Gitea/Forgejo, dev
containers, Gerrit, Vagrant: an off-port service on a host already in
known_hosts.

So the flags are per-pass now, and pass 0 decides as soon as it finds any plain
entry for the host. Which of the two rejections it reports only picks the
message; ssh calls both HOST_CHANGED.

Also drops the type check from the match test: byte equality already implies the
types agree, because the blob carries its own algorithm name and parsing rejects
any line whose declared type disagrees with it.

Reverting either half of the scope fix fails exactly the two new tests.
1,526 SSH tests pass.

* fix(ssh): refuse the known_hosts lines ssh itself refuses to parse

Three ways a line could be trusted by us and invisible to the user's own ssh —
or, worse, raise a CHANGED alarm from an entry ssh drops.

Buffer.from does not fail on bad base64, it SKIPS invalid characters, so
`<key>!!!` and a blob with `@@` spliced into it both decoded to the correct key
and matched. Verified live against OpenSSH 10.2p1 on 127.0.0.1:2224: the
unmodified control reached authentication and all three malformed variants
produced "No ED25519 host key is known". A re-encode-and-compare makes us agree.

`<key>AAAA` is the interesting one, and the reason the first fix was not enough:
68 characters plus 4 is still legal base64, and the algorithm header still reads
ssh-ed25519, so neither the base64 check nor the existing header check sees
anything wrong. ssh parses the whole key structure. We decoded 54 bytes where an
ed25519 key is 51 and reported `mismatch` — a man-in-the-middle warning caused by
a typo in a file ssh silently ignores.

So the blob is now walked as what it is: a run of length-prefixed fields that
must consume it exactly. Algorithm-agnostic on purpose, so a key type we do not
model is checked as well as one we do. It also rejects a length prefix that
overruns the buffer, which readHostKeyType only checked for the first field.

And ssh's extract_salt demands exactly one SHA1 digest — "expected salt len 20,
got 16" — where we accepted any non-empty salt. A short salt is still a usable
HMAC key for us, so a hand-crafted line could match for us and be a parse error
for ssh. ssh-keygen -H always writes 20 bytes, so refusing loses no real entry.

Worth recording that ssh-keygen -F cannot answer any of this: it matches host
names and prints lines without ever decoding the key, so it reports "found" for
all four blobs. The real client was the only instrument that worked.

Found by a parity review; the base64 finding as reported was right about the
behaviour and wrong about the mechanism for the padded case, which is what led to
the structural check.

1,533 SSH tests pass.

* fix(ssh): name a ssh-keygen -R target that actually removes the entry

Verified against OpenSSH 10.2p1: with both `[h.example]:2222` and `h.example`
on file, `ssh-keygen -R h.example` removes only the bare line and leaves the
bracketed one — and there is no port flag, `-R host -p 2222` is "Too many
arguments". An off-port target is keyed `[host]:port` in known_hosts, so the
command we printed removed nothing: the user runs it, reconnects, and meets the
identical failure with no indication of why.

The message now names the bracketed form, quoted because the brackets are shell
glob characters, whenever the port is not 22.

Found by a parity review.

* fix(ssh): read ssh2's host key algorithm list instead of copying it

ssh2 builds DEFAULT_SERVER_HOST_KEY at load time and prepends ssh-ed25519 only
when a RUNTIME PROBE succeeds — it signs and verifies with a fixed Ed25519 key.
On a build where that probe fails, ssh-ed25519 is absent from ssh2's SUPPORTED
list too, and generateAlgorithmList throws `Unsupported algorithm: ssh-ed25519`
from inside client.connect. That throw matches no retry classifier and no
transport-fallback classifier, so it is permanent — and because we only set
`algorithms` for hosts we already know, it would fire on trusted hosts while new
ones kept working. A copied list cannot be merely stale here; it can be wrong.

So it is read from ssh2 now, which also removes the drift risk the previous
commit could only report. ssh2 is external in the main bundle and the bundle is
CJS, so the deep path resolves at runtime from packaged node_modules.

The copy stays as a fallback in case a future ssh2 moves the file — losing the
proposal order degrades the type-scoping guarantee, but refusing to connect at
all is worse. The test that used to pin the copy against ssh2 now pins the
fallback, which is the only part that can still drift.

Found by an availability review.
pnpm lint clean; 1,537 SSH tests pass.

* fix(ssh): look a HostKeyAlias up the way ssh does — without the port

HostKeyAlias suppresses the port entirely. Verified against OpenSSH 10.2p1 on
port 2225 with HostKeyAlias=myalias: an entry keyed `myalias` authenticates, and
one keyed `[myalias]:2225` gives "No ED25519 host key is known for myalias". We
built [['[alias]:port'], ['alias']] and consulted a form ssh never writes.

On its own that was a stale-entry false alarm. The previous commit made it worse:
now that the first pass decides as soon as it finds any entry for the host, a
leftover `[alias]:2225` line STOPS the bare lookup ssh actually performs — so the
one population D2 cites HostKeyAlias for, bastions tunnelled through
localhost:port, would get a hard failure on a host ssh connects to.

So resolveKnownHostsLookupHost reports whether the name came from the alias, not
just what it is, and that flag reaches both the matcher and the algorithm
ordering. Returning the name alone is what made the bug invisible: the caller had
no way to know it was holding something that must not be bracketed.

Found by a parity review.
1,543 SSH tests pass.

* fix(ssh): only claim the site config was suppressed when ssh -G actually ran

sshGArgsForHost reports which arguments WOULD be used, not what happened. It
returns the -F form whenever ~/.ssh/config exists and os.homedir() diverges from
the passwd home, so a machine with no usable ssh at all — Windows without
OpenSSH, a restricted sandbox, a timed-out probe — was judged by whether it
happens to have a ~/.ssh/config, and rejected every unknown host permanently if
it did. The same broken machine WITHOUT one stayed fully permissive, which is the
tell: the flag is a claim about a config file we could not read, and when ssh
never ran there is no such claim to make.

Narrow but total where it lands: anything that sets HOME explicitly (wrapper
scripts, sudo -E, devcontainers), macOS mobile and network accounts, and the E2E
isolation this branch was written for.

Found by an availability review.

* fix(ssh): stop refusing hosts that ssh itself connects to

Two product decisions, both taken deliberately after a review priced their blast
radius, and both moving us from stricter-than-ssh to matching it.

CERTIFICATE-AUTHORITY HOSTS NO LONGER FAIL. The point of an SSH CA is that the
client holds ONE line — very often `@cert-authority *` — instead of per-host
entries. That line matches every candidate, so for a Teleport / Vault-SSH /
Smallstep / in-house-CA user EVERY target failed, not just CA-signed ones,
including on-demand runtime VMs, and StrictHostKeyChecking=no did not help. The
documented escape was an environment variable, which an Electron app launched
from the Dock or Start Menu never sees. Meanwhile OpenSSH, verified live, treats
a CA-covered host presenting a plain key as first contact and connects: ssh2
cannot validate certificates at all, so refusing bought nothing ssh was not
already giving up. The residual risk is real and accepted — for a CA-protected
host we take a plain key we cannot tie to the CA — and the ca-only outcome is
carried through the decision so it stays visible in the log.

AN UNREADABLE known_hosts NO LONGER REFUSES EVERYTHING. Any non-ENOENT read
error on any configured file rejected every unknown host, with a message blaming
the system SSH configuration, which was not what happened. The common trigger is
not exotic: a Windows OneDrive Known Folder Move placeholder while offline fails
with a cloud-file error, not ENOENT. It was also asymmetric with our own store,
which degrades an unreadable file to "nothing trusted" and connects. We now
connect as ssh does — it warns and treats the host as unknown — but record
NOTHING, so a first contact we could not check never becomes durable trust. That
second half is the reason the first is acceptable, so it is pinned end to end
with the store actually bound.

Which meant splitting verificationSourcesIncomplete back apart. It had been one
flag for two claims that now diverge: "a site policy may exist that we cannot
read" still refuses, "a file we could not open may contradict this" does not.
Merging them was what made the second inherit a strictness only the first
justified.

Both still lose to evidence we DID read: a mismatch, a revoked key, or an
explicit StrictHostKeyChecking still refuse in either state.

pnpm lint clean; 1,549 SSH tests pass.

* docs(ssh): correct the design where a live client disproved it

D2, D3 and D4 each stated something about OpenSSH that turned out to be wrong
when tested against a real client and sshd rather than read from the source.

D3's premise is the notable one: OpenSSH is not type-scoped at all, so it does
not avoid the RSA-era false alarm the way the doc claimed. It avoids the
situation via order_hostkeyalgs and hard-fails when the situation arises anyway.
The conclusion survives — the ordering is still what makes our scoping safe —
but for a different reason than the one written down, and a reader would have
drawn the wrong lesson.

D2 gains the two rules that actually bite: the entry condition to the fallback
pass, and HostKeyAlias suppressing the port. D4 records both reversals with their
reasoning and the residual risk each one accepts, and the ssh -G spelling trap
that made StrictHostKeyChecking dead on arrival.

Corrections are kept visible rather than edited out, per the note at the top of
the file.

* fix(ssh): repaint the panes after a reconnect, not just reattach them

Reported: disconnect an SSH host from the Remote Hosts popup, reconnect, and the
terminals come back blank — but resizing a split or toggling the sidebar makes
them render correctly.

That last detail is the diagnosis. The panes were never broken: reattach restores
each pane's buffer but not its painted frame. xterm repaints on a write or a
resize, and a reconnect produces neither for a pane that was already correctly
sized — so nothing paints until a relayout forces it, which is exactly what
resizing or toggling the sidebar does.

The renderer already has refitAndRefreshAllTerminalPanes for this shape ('after
bulk desktop restore, background panes may have correct cols/rows but a stale
xterm renderer until focus forces a repaint'). Its only callers were the mobile
fit-reclaim paths; the SSH reconnect path never used it.

Scheduled from finalizeHydratedTerminalPanes, on both a frame and a 100ms settled
pass — the same pattern the desktop-restore path uses, because rAF alone lands
while panes are still remounting.

Mutation-proved: removing the schedule reddens the new test, which is the
reported symptom.

* fix(ssh): repaint background-tab panes revealed after a reconnect

Completes 834a495038, which only fixed the ACTIVE tab. Reported: split panes of
plain shells on another tab were still blank after reconnect until a divider drag
or a sidebar toggle.

The repaint did reach background managers — they stay mounted, only
rendererVisible flips — but it could not land. A tab-hidden pane measures as a
0-size box, so canMeasurePaneForFit bails and the fit is a no-op, and
refreshAllPanes marks rows dirty on a pane with no presented frame, which cannot
repair a grid the reattach's direct terminal.resize left diverged. The reveal
then takes the light resume path, which deliberately does not fit, and
scheduleRevealRepaint only reattaches WebGL. So nothing ever fixed the geometry —
and a divider drag or sidebar toggle is a real fit, which is why those appeared
to work.

Parks the repaint on a hidden manager and replays it on reveal, reusing the
existing reveal-fit machinery rather than adding a mechanism. Flag-gated so the
light path still does not fit in the ordinary case — 'does not fit on a light tab
reveal' stays green.

Splits are not special: the gap is per-manager, so it is identical for 1 or N
panes. Splits just expose it, because users find the workaround (drag a divider)
that a single full-tab pane rarely gets. A never-mounted tab is unaffected — it
has no live manager and fits through the normal initial-fit lifecycle.

Mutation-proved twice: removing the deferral, and reverting the reveal-side
condition. Each reddens only the new tests.

* test(terminal): pin that panes are PAINTED, not merely bound — and fix a broken commit

Two problems, both mine.

1) 0103a80b48 swept in an untracked fixture and left the branch failing
typecheck (unused Terminal import in painted-pane-fixture.ts). Its canvas stub
also threw 'clearRect is not a function' on every refresh. Fixed here.

2) direct-ssh-reconnect-repaint.test.ts, which I wrote to guard the reconnect
repaint, is VACUOUS: it re-implements finalizeHydratedTerminalPanes inside the
test and mocks the registry, so deleting the real fix from useIpcEvents leaves it
green. direct-ssh-reconnect-repaint-wiring.test.ts replaces that guarantee by
capturing the real callback the hook hands the coordinator and running it against
live panes — deleting the two scheduling lines now reddens it.

The gap this closes: content survival was already well covered at the BYTE layer
(snapshot roundtrip, hide/reveal stitching, cold-restore scrollback), but every
pane test stubbed terminal as {cols, rows, refresh: vi.fn()}, so 'repainted' only
ever meant 'a spy fired'. No test ran a real xterm through a real PaneManager.
pane-content-survival.test.ts does, reading .xterm-rows — what the user actually
sees — across reconnect, restart-shaped restore, tab reveal, window show, split
and unsplit, for plain shells and alt-screen TUIs.

The alt-screen distinction is now pinned explicitly: forcing a resize inside
fitAllPanes reddens only the TUI test, because a plain shell reflows and survives
while a TUI frame does not. That asymmetry is why the reported bug looked like a
plain-shell problem.

11 tests, each mutation-proven to redden only its own. 760 pane-manager tests
green; the 2 failures here are the known environmental IME baseline.

Flagged, not fixed: the unsplit path reparents the DOM without the dispose/
reattach that splitManagedPane does explicitly because 'DOM reparenting can
silently invalidate a WebGL context without firing contextlost', and follows it
with a safeFit that no-ops when the box is unchanged. Same shape as the reconnect
bug. happy-dom has no WebGL, so only a real-GPU E2E can confirm it.

* fix(ssh): send the pane its screen back on reconnect

A reconnect left every remote terminal blank. Measured on a live relay, not
inferred: pty.attach returned no replay for every pane, taking the
activation === 'existing' early return in the relay's attach.

'existing' means a source delivery is already open for this client, so it must
already be receiving live output and cannot need its screen re-sent. That holds
for a duplicate attach. It is false for a reconnect, for a reason neither side
can see alone: the client keeps its id across the drop (detachClient refuses to
detach the primary, and setWrite revives that same id) so the delivery outlives
the dead transport, while the RENDERER has already thrown its terminal away. A
reconnect bumps tab.generation, which is the pane's React key, so TerminalPane
remounts and the old xterm is disposed with its buffer, and nothing on that path
captures it first. Both halves are individually reasonable and together they
guarantee a blank pane: the relay reports the client already has the screen, to a
client holding a brand-new empty terminal, and nothing paints until new output
happens to arrive. Resizing appeared to fix it only because a TUI redraws itself.

So the client says which case it is. reattachSshPtySession is by definition
painting into a new terminal, so it asks; nobody else does, and the early return
keeps working for them. Optional on the wire, so an older relay ignores it and
behaves exactly as it does today.

Falling through rather than returning the replay inline is deliberate: the path
below already drops the pending batched bytes that are also in the buffer, which
is what stops the live delivery rendering them twice.

Reproduced first as a test against the real dispatcher, source publication and
PTY handler (the second attach for one client, which is what a reconnect is) and
it fails on the exact symptom before the fix. A second test pins that a caller
which does NOT ask still gets nothing, so this cannot become a double-render for
the duplicate-attach case the early return exists for.

Also updates four provider tests that assert the exact attach params.

NOT yet verified in the running app; the log will show replay=true on reconnect.

* chore(ssh): drop the temporary reconnect-replay diagnostic

Served its purpose: it is what turned 'the panes look blank' into
replay=false, replayLen=0 on every pane, and then into replay=true with real
byte counts once the relay fix landed. The permanent log line keeps the boolean,
which is the part worth having.

* revert: drop the reconnect repaint commits; they cannot fix the blank panes

Reverts 2fdab478c0, 34fc1424f0 and dc6f6bf685, which I cherry-picked onto
this branch to test alongside the host key work.

Their stated premise is 'reattach restores each pane's buffer but not its
painted frame'. That is false for this flow: a reconnect bumps tab.generation,
which is the pane's React key, so TerminalPane remounts and the old xterm is
disposed WITH its buffer, and nothing on that path captures it first. Refitting
and refreshing a terminal whose buffer is empty paints an empty pane. The blank
screen was the relay declining to re-send the scrollback, fixed separately and
verified on screen.

Their tests pass without exercising the real case: the fixture blanks the
painted rows and deliberately LEAVES THE BUFFER INTACT, which is the one
situation that never occurs here, and the hidden-tab test replaces the pane
manager with a stub that reports no panes.

They may still address a separate symptom — a diverged grid after a resize on a
hidden tab — but that is unproven, unrelated to this branch, and the originals
are untouched on nwparker/sta-3077-fix-v3 where they came from. Carrying
unproven renderer changes with a false premise in their message on a
security-focused branch is not worth it.

Reverting first and re-running the full two-step reconnect test is the point:
the earlier verification passed with these present, so it did not establish that
the relay fix stands alone.

* fix(ssh): repaint a reconnected pane from the grid, not a byte tail

A reconnect restored plain shells correctly but was reported to bring full-screen
apps back as fragments of a frame — Claude Code showed a few rules and its cost
line until a resize forced it to repaint.

The two payloads are not interchangeable. Relay replay is a byte TAIL: it can
begin mid-escape, and it misses the alt-screen enter, the clears and the absolute
cursor positioning that built the frame, so replaying it into a fresh terminal
paints whatever fragments survive. The model snapshot is a serialized GRID —
which is what tmux repaints on attach, and the only payload that reliably
restores a TUI.

Orca already had the grid path and already preferred it; it was gated to PARKING.
A reconnect needs it for the same underlying reason a park does: the pane paints
into a terminal holding nothing, because a reconnect bumps tab.generation, which
is the pane's React key, so TerminalPane remounts and the old xterm is disposed
with its buffer. So the gate now admits both, and prepaintParkedSshSnapshot is
prepaintSshModelSnapshot since parking is no longer the only caller.

Deliberately NOT inheriting the parking kill switch: main keeps its headless
model regardless of terminalSshViewParking, so a user who turns view parking off
would otherwise be stranded on the tail.

Every safety gate below eligibility is untouched, and pinned that way: null,
renderer-sourced, sourceless, empty, and escape-tail-only snapshots all still
degrade to relay replay, so widening WHY the model is trusted cannot widen WHAT
is trusted and cannot regress to a blank pane. Reverting either half of the gate
fails three of the new tests.

HONESTY ABOUT WHAT THIS IS VERIFIED TO DO. I could not reproduce the corruption
it targets. Two attempts against a live host, both on a build WITHOUT this
change, both restored correctly: a freshly started Claude Code and Codex side by
side, and an alt-screen `less` scrolled 4000 lines so its original full paint had
aged out of the relay's 100KB tail. The reporter's case also involved pulling
wifi — an abrupt drop rather than a clean disconnect — which is the one variable
I cannot simulate here.

So this is verified to be correct-by-construction and non-regressing: with it
applied, the same scenarios still restore correctly (top live, less at its
scrolled offset in alt-screen, both agent TUIs coherent). It is NOT verified to
fix the reported symptom, because the symptom did not reproduce. Treat the
symptom as open until someone confirms it on an abrupt drop.

Also: top was a poor proxy for a TUI in my earlier verification precisely because
it repaints every second and therefore self-heals within a tick.

* fix(ssh): stop the reconnect prepaint firing after its mount is spent

Regression I introduced with the snapshot-first reconnect paint. The payload path
consumes mountFollowsTerminalPark — it clears the flag after the first reattach
so a later in-place reconnect on the SAME mount cannot repaint. I replaced the
prepaint's read of that mutable flag with a const snapshot of it, so my combined
flag stayed true for the life of the mount. A snapshot could then be written on a
later reattach, into a terminal that already had live content, and its own
isCurrent() guard could no longer go false either.

The visible symptom was a tab that came up blank with no prompt and stayed
generically titled Terminal N — the title only stays generic when the shell never
printed a prompt for Orca to read one from. Every such tab in my session had been
through a remount; four tabs created cleanly with Cmd+T were all fine.

So the flag is mutable again and is consumed alongside the one it was derived
from. Both reasons a mount paints into an empty terminal — a park and a reconnect
— are spent by the first reattach, which is what the original code meant.

Worth stating plainly: my earlier claim that the snapshot change was
non-regressing was tested only against reconnect scenarios. I never exercised
creating a tab afterwards, which is exactly where this showed up.

* test(ssh): cover what a pane SHOWS after a reconnect, and after a new tab

The gap that let both regressions reach a user. Nothing asserted the rendered
pane: the existing SSH coverage checks pty ids, statuses and spy calls, and every
one of those was correct while the screen was blank.

Covers one flow end to end against the dockerized relay: write a marker,
reconnect, require the marker to still be on screen, then open a tab and require
the new shell to answer.

Three choices worth keeping:

A MARKER, NOT A PROMPT. A prompt reappears on its own after a reconnect, so
asserting one cannot tell restored scrollback from a fresh shell. The marker only
exists if the pane kept what it had.

ECHO, NOT EXISTENCE. The new tab must run a command and show its output. A pty
id proves a session was created; it does not prove the pane is usable, which is
the exact distinction the reported bug lived in.

AND THE TAB TITLE. It stays 'Terminal N' only when the shell never printed a
prompt for Orca to read one from, which is what the report showed and the
cheapest signal available.

Gated on ORCA_E2E_SSH_DOCKER=1 like the other relay specs.

* chore(ssh): rename the snapshot prefetch off its park-only name

The probe serves reconnect remounts as well now, so parkedSshSnapshotPrefetch
described only half of what it holds.

* revert: drop the snapshot-first reconnect paint; unproven and it regressed

Reverts e6541fe9b8, its follow-up c497a26788, and the rename f680a0b1cb.

The reasoning behind it still looks right — a byte tail cannot rebuild an
alt-screen application, a grid snapshot can, and that is what tmux repaints on
attach. What I could never do is show it fixing the reported symptom. Two
attempts to reproduce the corruption on a build WITHOUT it both restored
correctly: freshly started Claude Code and Codex, and an alt-screen `less`
scrolled 4000 lines so its full paint had aged out of the relay's 100KB tail.

Meanwhile it cost two real regressions. It fired on mounts that were not
reconnects, leaving a new tab with no prompt and a placeholder title, which a
user hit within minutes. The fix for that consumed the eligibility flag with the
one it was derived from — and after it, a reconnected Claude Code came back as
fragments of a frame, the exact symptom the change was meant to remove. So the
consume-once semantics that stop stale paints and the repaint a reconnect needs
are in direct tension, and I do not yet understand the ordering well enough to
satisfy both.

Shipping an unproven change that has already broken two things twice is worse
than shipping the blank-pane fix alone, which IS reproduced, A/B'd and visually
verified. The TUI corruption goes back to open — but now with something it never
had before: a reproduction. It shows up on a reconnect against a Claude Code
that has been running a while, not one just started, which is why my earlier
checks kept passing.

The e2e coverage stays. It asserts what the relay fix guarantees — a marker
surviving a reconnect, and a tab opened afterwards reaching a shell that answers
— and neither of those depends on this change.

* docs(ssh): name the root cause the reconnect replay fix does not address

requireReplay fixes the blank pane at the symptom. The cause is that a PTY
source delivery is the only per-client relay state that outlives its client
detaching: fs-handler, git-handler and relay-filesystem-watch-registry all
subscribe to dispatcher.onClientDetached and release theirs, and
relay-pty-source-publication never does. The primary client keeps its id across
a transport replacement, so its delivery survives a dead transport and
activate() answers 'existing' to a client that cannot receive anything.

Retiring the delivery on detach is the real fix. Not doing it here is a choice,
not an oversight — it is the flow-control and credit path, and I could not
verify it before handing this over. Recorded in the test that guards the
symptom, which is where someone changing this will actually look.

* docs(ssh): record the three root-cause routes that do not work

I went after the cause and failed three times. Each attempt looks correct until
it runs, so the dead ends are worth more written down than the time they cost:

RETIRING THE DELIVERY ON onClientDetached — the obvious fix, and the one I
argued for, since fs-handler, git-handler and the watch registry all release
their per-client state exactly there. It breaks checkpoint recovery: 10 tests
across relay-pty-source-recovery-interleavings and restore-retry. A delivery
outliving its client is DELIBERATE; that is what lets a reconnecting client
resume from a checkpoint instead of re-receiving everything. This class omits
the subscription on purpose, and that omission is not the bug.

RETIRING WITHOUT session.cancelDelivery() — the credit ledger keeps one upstream
owner per pty, so dropping the record without releasing it leaves the slot
taken and the next open throws 'PTY source delivery already has an upstream
owner'. I saw that live as an error toast over a blank pane.

COMPARING clientGeneration — the delivery identity carries one, but it is
client-supplied through pty.openClient and RequestContext has none to compare
against, so the relay cannot tell the generations apart on its own.

Which points where I would start next, unverified: the SSH client presents the
SAME clientGeneration across a reconnect, so the relay cannot distinguish the new
connection and reuses its delivery. reattachSshPtySession never sends
sourceRecovery at all — the recovery protocol exists and the SSH reattach path
simply does not participate in it. That is likely the real fix, and it is on the
client, not in the relay.

The symptom fix stays because it is verified and the tree is green; the cause
stays open with a map instead of a guess.

* fix(ssh): repaint a reconnected full-screen app from the grid

A reconnected TUI came back as fragments of a frame — Claude Code showed a few
rules and its cost line until a resize made it repaint itself.

Relay replay is a byte TAIL. It can begin mid-escape and it misses the
alt-screen enter, the clears and the absolute positioning that built the frame,
so replaying it into the fresh xterm a remount just created paints whatever
fragments survive. Main already keeps the thing that does restore a frame: a
real @xterm/headless grid, alt-screen aware, fed unconditionally for SSH. Local
terminals already repaint from it; SSH was the only path that did not.

So this routes an SSH reconnect into the painter that already exists, at the one
expression that chooses model over tail. No new call site, no second lifecycle,
and every existing gate still applies — a null, renderer-sourced or empty
snapshot still degrades to the tail, so it cannot paint blank.

ONLY ON THE ALTERNATE SCREEN, and that is the whole design. The reconnect replay
reaches the renderer without passing through main's model — forwardReattachReplay
and the inline attach replay both bypass onPtyData — so at that moment the model
is stale by exactly the outage. For a full-screen app that trade is right: a tail
cannot rebuild a frame it no longer contains, a grid can, and the SIGWINCH the
restore already sends makes the app redraw the delta. For a scrolling shell it
would be wrong: the tail holds output the model never saw, and preferring the
grid would drop it for good. A park has no such hole, so it keeps using the model
either way.

Derived from the PENDING retry, not directSshRetryAttempt. That also matches the
live binding, which is written at the same tab generation once a reconnect
succeeds and then outlives it — so it stays truthy for every later remount of
that generation. Reading it directly is what made my first attempt fire on mounts
that were not reconnects. Consumed alongside mountFollowsTerminalPark for the
same reason.

Verified live against the reported app: Claude Code restores identical to its
pre-disconnect frame, top restores coherent and live, and a plain shell still
shows output written before the disconnect. 5,470 tests pass across the touched
suites.

Not the whole story, and the remaining half is already written down: the model's
gap exists because the SSH reattach asks for a tail instead of participating in
the checkpointed resume the relay already implements. Close that and this paint
is not merely coherent but exactly correct, for shells too.

* test(ssh): cover a full-screen frame across a reconnect, not just scrollback

The case a byte tail cannot serve, and the one that reached a user twice. A tail
can begin mid-escape and misses the alt-screen enter and absolute positioning
that built the frame, so replaying it paints fragments — which is what a
reconnected Claude Code showed.

Uses top: present on any Linux image, and it repaints on a fixed interval, so a
whole header after the reconnect is unambiguous rather than a timing artifact.
Asserts the header AND the column row, because a tail that lost the frame start
still shows rows.

The spec now covers all three payloads one reconnect has to get right: a shell's
scrollback, a full-screen app's frame, and a tab opened afterwards reaching a
shell that answers.

* ci(e2e): actually run the Docker-SSH specs in the changed-specs lane

"I am surprised this was not caught" has a mechanical answer: these tests do not
run. A spec that reads ORCA_E2E_SSH_DOCKER test.skip()s itself when it is unset,
and exactly one place in CI set it — gated on tests/e2e/ephemeral-vm-provisioned-
root.spec.ts being among the changed files. So editing any SSH spec ran it as a
skip and reported green. Eighteen specs reference that variable, including both
reconnect regressions I have been chasing.

Now it is also enabled when any changed spec references the variable, which is
the same grep -l idiom the @headful check two lines below already uses. The
original clause stays: that spec needs Docker without naming the variable, so
replacing it rather than adding to it would have traded one silent skip for
another.

Simulated against the real files — the reconnect spec, the original trigger, a
multi-spec change, a non-Docker SSH spec, and a deleted path — enabling in the
first three, staying off in the last two, and not failing the step on a path that
no longer exists.

* fix(ssh): let the replay veto a stale alternate-screen belief

Adversarial review of the previous commit found a case where it is worse than
the bug it fixes, and it is the exact inverse of what that commit reasoned about.

The model reports alternateScreen from bytes it consumed, and it never consumes
the outage. So if a full-screen app EXITS during the disconnect — an agent
finishes, a command ends, the process dies — the model still says alternate. The
gate then painted a frozen frame of an application that no longer exists and, via
the else-if chain, discarded the replay carrying the shell's real output. Frozen
and wrong beats fragments, which were at least current bytes.

The replay is the only witness to the outage, so it now gets a veto: its last
47/1047/1049 transition, if any, outranks the model's belief. Leaving reset means
the frame is gone and the tail wins; re-entering means the model is right after
all. Same review found the width-mismatch guard drops the alt frame and leaves a
cleared screen for the app to repaint — free for a park with no tail to lose, but
here it meant discarding a usable one for a blank pane, so that degrades too.
Both vetoes are skipped when there is no replay, where they would only trade a
stale frame for an empty one.

Extracted as sshReconnectPaintsFromModel rather than more inline ternary, because
every interesting case is a disagreement between a stale belief and a replay —
awkward to stage end-to-end, trivial to state as a table. 14 unit tests, including
the two that fail against the previous commit. The e2e comment is corrected in the
same spirit: top redraws itself, so it never discriminated the paint source and
should not have claimed to.

Also from the review: the kitty flag stack was left stale on this path, since the
app's pushes during the outage exist only in the replay we discard — scanned now,
after the snapshot so the outage layers on the pre-outage baseline. And the
consume-once comment asserted an invariant that does not exist;
followsDirectSshReconnect is a const captured per connect, bounded by
connectStarted and the gates rather than by the read. Corrected rather than
restructured.

Known and NOT fixed, because it predates this work and is a behavior change of
its own: the model probe is gated on the terminalSshViewParking kill switch, so
turning off view parking also silently disables this repaint. Defaults on.

* docs(ssh): make the parking kill switch's reach over the reconnect repaint deliberate

Review flagged that terminalSshViewParking silently disables the full-screen
reconnect repaint, since both go through the same model probe, and that nothing
said so.

Keeping the coupling and documenting it rather than threading a reason through.
The switch is the kill for painting an SSH pane from main's model at all, and a
reconnect does exactly that; off should restore the relay-tail behavior that
predates the machinery, which is what an escape hatch is for. That matters more
than usual here: this repaint is new and review already found one case where it
was worse than the bug, so a way to turn it off in the field is worth its cost —
a user who disables parking also loses the reconnect repaint.

The alternative is worse than it looks anyway: the probe memo is keyed on ptyId
and shared with the park path, so a per-call reason would be reused by whichever
path created it first.

* docs(ssh): record why the obvious reconnect follow-up does not work

I proposed making the pane-retry path request source recovery the way
reattachKnownPtys does, and argued it was probably client-side routing. Tracing it
says the wiring is indeed trivial and the checkpoint state does survive a drop —
and that the change would still be wrong three ways, one of them harmful.

The relay short-circuits to 'existing' on a same-clientId attach BEFORE it looks
at the recovery argument, and the reconnecting client has already rotated the
delivery onto its id. A failed reattachKnownPtys then deletes the checkpoint on
purpose, so a later pane retry presents checkpointUnavailable, which becomes
restoreRequired and then SSH_SESSION_EXPIRED_ERROR — trading a blank pane with a
tail for a killed session. And the payloads answer different questions anyway:
recovery replays the post-checkpoint delta to keep main's model whole, while the
tail is a screen snapshot for a fresh empty xterm. Even a successful recovery
would put almost nothing in a remounted pane.

Also corrects the argument I had been leaning on hardest. "Old relays ignore
requireReplay, so those users still get blank panes" is false for the SSH relay:
the client deploys its own relay into a version-scoped directory and rejects any
grant whose serverBuildId differs, because client and relay ship in one build.
Mixed versions cannot occur on this channel. The independent-update rule still
governs remote runtime hosts, just not this one — so there is no stranded
population, and the urgency that framing created was imaginary.

What replaces it is a sharper question. Source recovery is gated on
outputFlowControl and on the client presenting a NEW clientId. We have empirical
evidence it does not: the blank-pane bug existed because the relay concluded this
client already held the stream, and the shipped fix works by bypassing that exact
early return. If the id is reused, reattachKnownPtys' recovery hits the same
short-circuit — meaning checkpointed recovery may never have run for SSH
reconnects, and the tail is not a fallback but the only path. Whether that is so
turns on daemon versus stdio-primary relay mode, which I did not verify and which
decides whether the work is "extend recovery" or "recovery has never run here."

* docs(ssh): the root cause — checkpointed recovery never runs on a reconnect

Chasing why the pane-retry path could not request source recovery turned up the
real answer: nothing can. Recovery is dead on every SSH reconnect, and the byte
tail is not a fallback but the only path that has ever run.

Five links, each read rather than inferred. setWrite reuses primaryClient
including its id, so a reconnected client presents the SAME clientId. activate()
tests exactly that at line 99 and returns 'existing' at 108, which makes the
rotateDelivery branch at 118-142 reachable only when the ids differ — never here.
So no sourceRecovery comes back, so finishSourceRecovery fails its
!pendingRecovery guard and abandons, cancelling the delivery and deleting the
checkpoint. The pane retry then opens fresh and takes the tail.

This also explains the blank panes exactly. The relay concluded that this client
already held the stream because, by its own identity rule, it does.

The fix that implies is smaller than anything proposed so far and avoids what
sank the three earlier attempts: bump a transport generation on the client record
in setWrite and compare it alongside clientId, so a reconnect rotates the delivery
instead of matching as 'existing'. Deliveries still outlive their clients and
nothing retires on onClientDetached — the rotation happens on re-attach, which is
what the recovery design already intends. RequestContext, setWrite and the
publication are all relay-internal, and client and relay ship in one build, so
there is no wire change and no compatibility exposure.

Left explicitly unverified: whether rotateDelivery's identity preconditions hold
at that moment, whether outputFlowControl is granted on the reconnected session,
and what a rotation gives the RENDERER — which still remounts an empty xterm and
needs a screen, not a post-checkpoint delta. Recovery keeps main's model whole; it
does not by itself repaint a fresh terminal, so the tail may still be wanted for
the pane even once the model stops going stale.

* ci(e2e): run the Docker-SSH specs when SSH SOURCE changes, not just specs

The earlier fix only helped when a spec file itself changed. Edit pty-connection,
pty-handler or ssh-relay-session and touch no test — which is what every one of
these regressions actually looked like — and the lane still did not run.

pr.yml now maps SSH source paths onto five Docker-backed specs. Five rather than
all fifteen because the rest are covered by unit tests that prove the same source
without paying for a container; that is a deliberate narrowing and this comment is
where it is admitted rather than left implicit. Test files are excluded from
triggering, since they prove themselves.

Simulated against the real paths this PR touches: pty-connection.ts,
pty-handler.ts, ssh-relay-session.ts and ssh-pty-session-reattach.ts all now pull
the SSH specs in, while pty-connection.test.ts, ssh-known-hosts.test.ts,
SshTargetCard.tsx and README.md correctly do not. The gate contract test covers
the mapping: 11 pass.

e2e.yml pays for it — 30 to 45 minutes, because the lane can now build a container
image and run SSH specs serially on top of whatever changed — and installs
openssh-client, which the fixture shells out to and which the lane did not need
back when it never received these specs.

* test(ssh): make the reconnect spec actually run — it now fails on a real bug

It had never executed once. The CI condition that enables Docker-SSH was gated on
an unrelated spec, so this skipped and reported green — and running it for the
first time found two bugs in the spec itself, both of which a typechecked tests/
would have caught instantly.

startDockerSshRelayTarget returns a DockerSshRelayTarget, which has no targetId;
the id comes from connectDockerSshRelayTarget's return value, which the spec
discarded. So every reconnect call passed undefined and the relay answered
'SSH target "undefined" not found'. And openNewTerminalTabInActiveWorkspace takes
the group to open into; called with no argument the new tab lands nowhere.

The third problem was the fixture rather than the spec. The image ships Debian's
/etc/bash.bashrc with the xterm title block commented out and an all-comments
/root/.bashrc, so its shell never emits OSC 0 — which is what Orca derives a tab
title from. The title assertion could not have passed for any shell, healthy or
not, so it was proving nothing. enableDockerSshRelayTargetShellTitle opts a spec
into the title-setting PS1 a real user's shell already has.

IT STILL FAILS, and that is the point: it fails on a PRODUCT bug it was written to
catch. An SSH reconnect destroys the terminal state behind a tab whose local
creation has not yet reached the host. remote-workspace-session-merge.ts:86-89
spreads the host's tab list over the local one for that worktree, so a local tab
missing from the host snapshot has no surviving branch; the upload that would have
put it there is DROPPED rather than deferred inside the 1s suppression window
after a snapshot apply. The tab bar still renders the tab, correctly titled, but
the terminal slice holds one tab and no pane manager exists for the second — so
the user clicks a tab that never paints, with no error and no recovery, while the
process keeps running on the host.

Pre-existing: none of remote-workspace-target-sync.ts,
remote-workspace-session-merge.ts, use-app-session-persistence.ts or
remote-workspace-snapshot-apply.ts is touched by this branch, and nothing in the
merge range touches them either.

Not worked around here. Waiting for the upload would hide it, and a user opening a
tab right after a reconnect has no such signal to wait on.

An earlier version of this message claimed the spec passes. It does not; I had
seen five green runs out of six and generalised from them. Sustained runs are
about three in eleven before the merge and zero in four after.

* chore(e2e): add a typecheck entry point for tests/, unenforced for now

tests/ has never been typechecked. That is how a spec could read target.targetId
off a type with no such field, and call a function without its required argument,
while the suite reported green — the spec was skipping, so nothing ever
disagreed with it.

Pointing tsc at tests/ finds both immediately. It also finds ~198 errors across
~94 files, which is a cleanup project rather than a change to make here, so this
ships as pnpm typecheck:e2e and is deliberately NOT added to the typecheck chain
or to CI. An unenforced script is worth less than a gate, but it is worth more
than nothing: it is runnable, it is discoverable, and the header says plainly
what it is so nobody mistakes it for coverage we have.

runtime-types.ts is the one fix included, because it was actively misleading:
every PaneManagerLike method was optional, so every call site was a
possibly-undefined invocation that TypeScript could not help with. They are real
methods on a real instance. Also widens AppStore to the StoreApi that
window.__store actually is.

* test(ssh): separate the reconnect paint guard from the tab-destruction bug

The paint guard was failing about two runs in three, and after the merge every
run, for a reason that has nothing to do with painting. It staged its full-screen
check in a tab it had opened AFTER a reconnect — which is exactly the tab an
unrelated session-sync bug destroys on the NEXT reconnect. Two independent
failures were riding on one assertion, and the one that fired was not the one the
spec is for.

Running top in the ORIGINAL tab fixes it. That tab predates every reconnect, so it
is in the host snapshot and survives. No assertion changed, none were weakened,
and the new-tab case simply moves after the full-screen case rather than before
it — it still opens its tab after a reconnect, which is the regression it exists
to cover. Five consecutive runs pass at ~13s, against three in eleven before.

The bug itself is not swept up. ssh-reconnect-tab-destruction.spec.ts records it
as a fixme with the mechanism written down: session-merge spreads the host tab
list over the local one, so a local tab missing from the host snapshot has no
surviving branch, and the upload that would have put it there is dropped rather
than deferred inside the 1s window after a snapshot apply. It is worse than a
vanishing tab — the tab bar keeps rendering it, correctly titled, while the
terminal slice has dropped it and no pane manager exists, so the user clicks a
selected tab that never paints, with no error and no recovery, while the process
runs on untouched.

fixme rather than a workaround because waiting for the upload would hide it, and a
user opening a tab right after a reconnect has no such signal to wait on. It is
pre-existing: none of the four files in that path is touched by this branch, and
nothing in the merge range touches them either.

Also lifts openTerminalTab into a shared helper, since both specs need it and the
group argument it must pass is the kind of thing worth stating once.

* fix(ssh): stop a reconnect deleting local state the host has not seen

Reported from a 60-second manual test: reconnect an SSH workspace and the app
drops to the home screen, a second tab running pnpm install is gone entirely, and
one launched agent is listed twice. Three symptoms, one cause.

The snapshot is applied as the whole truth for the reconnecting target. The tab
merge iterates only the host's worktrees, then the result is spread over a gap
where every local tab for that worktree has just been dropped — so a tab created
locally whose upload has not landed has no branch that keeps it. Not a race: it
cannot survive. Same for the pointers, where a snapshot that names no active
worktree nulls activeWorktreeId and activeWorkspaceKey, which is the home screen
while the user's terminals are still running.

So the host is now authoritative for what it knows and not for what it has never
been told. A local tab absent from the snapshot is kept, the worktree union is
used so a snapshot with no entry for it at all cannot erase it, and a null active
worktree only defers to local state when that workspace demonstrably still exists
in the merged result.

Two guards this change had to earn rather than assume. A null activeTabId is NOT
missing information — it is a deliberate deselect that arms the duplicate-tab
repair, and my first attempt defeated it and broke that test; it is honoured
verbatim now. And preserving by tab id alone reintroduces the duplicate agent,
because the host can carry the same session under a new tab id, so the preserve
also checks the remote session id — the identity that survives a tab-id change.

Testing, which is the part that failed here before. Eight tests fail on the
unfixed code and pass on this one, at two levels: the merge decision table, and
the real apply path driven through a store. The end-to-end version of the same
scenario is deliberately NOT the guard and now says so in its header — measured
against unfixed code it only reproduces about one run in three, because the
destruction needs the tab created inside the debounced upload's suppression
window and nothing external can force that. Its earlier green run is exactly why
this shipped.

* fix(ssh): let agent session history recover once the relay is ready

Reported against the adhoc build: a workspace whose editor was loading remote
files perfectly still showed "SSH relay is not ready" and "0 shown · 0 recent" in
the Agent Session History panel, permanently.

That string is what the relay throws before it is ready, which is ordinary at
startup and again for the window a reconnect leaves the session not-ready. The
panel had three refresh triggers — mount, window refocus, and a newly seen agent
session id — and none of them fire when the relay simply becomes ready. So a
transient startup error became a stuck panel next to a workspace that plainly
worked, which is why the report described it as broken while everything else was
fine.

The file explorer already recovers from exactly this, off exactly this signal,
with the rationale written down at use-file-explorer-tree-load-effects.ts: it
loads before SSH providers are registered, so it retries when
sshConnectedGeneration bumps. This panel simply never did. Same idiom, same gate —
only retries when there was a prior error, so a local workspace or one that
already listed fine does not rescan every time some unrelated host connects.

Two tests in the existing suite. The retry one fails on the unfixed code with
"the panel never retried after SSH became ready"; the second pins the gate, since
a retry that fires on every connection bump would turn one bug into a rescan
storm.

* fix(worktrees): name the create route when a raw filesystem error escapes

A worktree create over SSH failed with a bare
"ENOENT: no such file or directory, lstat '/home/neil/projects/orca-test1234'".

That message names nothing. An lstat is Node's LOCAL filesystem, so hitting one
against a path that lives on an SSH host means creation ran a local
implementation for a remote repo — but the user cannot know that, and neither
could I without re-deriving the routing by hand and then failing to reproduce it.

worktrees:create picks between three implementations, and the order matters:
isFolderRepo is consulted BEFORE connectionId, so a folder-kind repo on an SSH
host never reaches the remote path at all. Which route ran, and what the repo
looked like when it was chosen, is the entire diagnosis — and it is knowable
exactly at the throw site, where the decision was just made. So it is stated
there now: route, repo kind, connection id, path, and the original message.

Deliberately additive and deliberately narrow. Only ENOENT/EACCES/EPERM are
rewritten; a git failure, a relay-not-ready, or a validation error already says
what went wrong and burying it under a worse message would be a regression. The
original error is kept as `cause`, so anything matching on `code` or reading the
stack is unaffected.

This does NOT fix the reported failure — I could not reproduce it. On current
code I created a worktree at that exact path, at a second path, with a leftover
directory already present remotely (correctly suffixed -2), and with the SSH
target disconnected (clean actionable error, no ENOENT). What it does is make the
next occurrence identify itself in one screenshot instead of costing another
investigation.

* fix(ssh): recognise a missing path reported by the relay

Creating a worktree over SSH failed with a raw
"ENOENT: no such file or directory, lstat '/home/neil/projects/orca-test1234'".

The path was the one about to be created, so its absence was correct. The caller
asks exactly that question — remotePathExists returns false on ENOENT — and could
not get an answer, so it rethrew at the user instead.

The trace log settles where the error comes from, and it is not where I spent a
long time looking. The stack starts at SshChannelMultiplexer.handleResponse: the
lstat ran on the SSH HOST, and the failure travelled back as JSON-RPC. An lstat in
an ENOENT message is normally Node's local filesystem, which sent me hunting for a
local fs call on a remote path; there is none.

handleResponse rebuilds the error as `new Error(msg.error.message)` and then sets
`code` from `msg.error.code` — the TRANSPORT's numeric JSON-RPC code. Node's
'ENOENT' string code does not survive that, and isENOENT tested only for the
string, so a remote missing path could never be recognised as missing. Every
caller of that predicate asks the same question, so this was wrong for all of
them, not just worktree create.

The message is now consulted as well, matched on Node's full canonical phrase so a
branch name or log line that merely contains the word cannot make an existing path
look absent — that would silently skip a collision check rather than report one.
Fixed on the client because it holds for every relay version, including ones
already deployed; teaching the relay to send the original code would only help
hosts redeployed afterwards.

The two other copies of this predicate, in filesystem-rename-collision and
git-discard-path-safety, are deliberately left alone: both run against a local
filesystem — one inside the relay, one on the desktop — where the string code is
intact and broadening would only add false positives.

Seven tests, three of which fail on the unfixed code: the relay-rebuilt error, the
same error through the IPC wrapper the renderer sees, and one carrying no code at
all.

* revert: drop the worktree-create error-context wrapper

Written to make an unexplained ENOENT self-identifying when creating a worktree
over SSH. The cause is now known and fixed — the error came back from the RELAY
and isENOENT could not recognise it, because the multiplexer rebuilds a remote
error with the transport's numeric code — so the wrapper is scaffolding for a
solved problem.

Worse, its central claim is false. It reported 'the remote (SSH) path failed on a
local filesystem call', and the trace log shows the lstat ran on the SSH host, not
locally. Keeping a message that asserts the wrong thing about the one failure it
was built for is worse than not having it.

183 lines and a rewritten error at the IPC boundary, removed.

* docs(ssh): drop a comment claim about older relays that is not true

The requireReplay comment said the field is optional on the wire so an older relay
ignores it. It cannot happen: the client deploys its own relay into a
version-scoped directory and validateGrant rejects any grant whose serverBuildId
differs, so client and relay are the same build by construction.

The field IS optional, which is why the relay reads it as !== true — that part
stands on its own and needs no story about versions. A comment asserting a
compatibility property the code does not have is worse than no comment, because
the next person plans around it.

* fix(ssh): act on the host key review — three must-fixes and two hazards

M1. A stale record of ours outranked known_hosts, so the remedy we print did not
work. `ssh-keygen -R host` then reconnect leaves known_hosts holding the NEW key
while our store still holds the old one, and the store was consulted first — the
one state that cure produces was the one state we refused. Permanently, since
nothing in the app clears the store. known_hosts now decides a match first, which
concedes nothing: it is the artefact ssh itself obeys, so an attacker who can
rewrite it has already won. Both directions of the precedence are pinned now; the
rotation case fails without this change.

That leaves one rejection known_hosts cannot cure — a host trusted only on first
contact that later rotates its key. "Remove the saved key" named nothing a user
could find, so it now names the store file.

M2. A superseded attempt could put a passphrase prompt in front of a host we had
just refused. The verifier deliberately does not record a rejection for an attempt
nobody is waiting on, so nothing identified it and ssh2's generic handshake error
walked the credential ladder. Guarded on the generation, which catches it whatever
the error turned out to be. Deliberately NOT by rejecting with a cancellation: an
existing test pins that connect() still reports the raw late-startup error, and
that behaviour did not need to change to fix this.

M3. Every unknown host was refused whenever HOME diverges from the passwd home —
devcontainers, `su`, Nix shells, some corporate launchers — because `-F` makes ssh
ignore /etc/ssh/ssh_config and being blind to a site policy was treated as reason
to refuse. Being blind is only a reason to refuse if we cannot go and look, so it
now asks ssh for the system config on its own and takes the stricter of the two.
Only a probe that fails leaves the strict rule standing. Costs one `ssh -G` on the
rare path that already needed -F.

N1. A rejected key's fingerprint was still adopted, and the relay scopes install
locks by it — locks keyed to a host we refused to talk to.

N2. The fallback algorithm list re-introduced the throw its own comment describes.
ssh2 prepends ssh-ed25519 only when a runtime probe succeeds, so on a build where
that probe fails, proposing it makes generateAlgorithmList throw inside
client.connect — and only for hosts we already know. Not reading ssh2's list is a
reason to leave its defaults alone, not to guess: it returns null now and the
caller skips reordering.

1555 tests pass in src/main/ssh.

* docs(ssh): state the merge's real trade instead of claiming it has none

The preserve comment said a genuinely closed tab is never in the local list,
because closing removes it. True for a close on THIS client; false for one closed
on another client sharing the host, where the tab is still local, still absent
from the snapshot, and now kept.

That is a deliberate trade, not an oversight — absence cannot distinguish 'never
uploaded' from 'closed elsewhere', and the outcomes are not symmetric: keeping a
tab a moment too long is recoverable by closing it, deleting a live one with a
process in it is not. But the comment asserted the case could not arise, which is
the kind of claim that gets planned around. Now stated, and pinned by a test so
the next person can see it was chosen rather than missed.

* fix(ssh): stop a newer host key store being silently downgraded

The store writes a version and never read it back. A file from a future Orca would
have had every record dropped by validateRecord — the shape would not match — and
then been REWRITTEN as version 1, so a rollback silently discarded whatever that
version knew. Trust records are user-owned state; losing them costs a
first-contact prompt per host and, worse, re-establishes trust from nothing.

v1 is the only place this can be made safe, because v2 cannot retrofit a v1 that
already clobbers it. A newer file is now left alone: nothing is trusted from it,
and trustHostKey declines to write rather than downgrade. The check sits inside
the snapshot queue so it cannot be separated from the write by another writer, and
declining is not an error the caller fails on — the key still verified, and the
next connect re-derives the same decision from known_hosts.

The test writes a version-99 file and asserts it is byte-identical afterwards; it
fails on the unfixed code with the file rewritten as version 1.

* perf(ssh): skip the reconnect snapshot probe the replay has already ruled out

Every SSH reconnect paid up to the 750ms model-snapshot timeout, including the
ones where the answer was discarded. The gate needs the snapshot's alternate-screen
flag, so the probe looked unavoidable — but one of its two vetoes does not: if the
replay shows the app LEFT the alternate screen, no snapshot can be used whatever it
says.

Asking that first costs a regex over the replay and removes the probe entirely for
that case. It also shrinks the window that matters most: the await sits inside the
structural replay coordinator with live PTY bytes deferred, and the payload can be
superseded while it runs.

Behaviour is unchanged — sshReconnectPaintsFromModel returns false for a null
snapshot exactly as it did for a fetched one it then vetoed, and its tests still
pin both vetoes.

* test(ssh): cover the site host key policy probe

It shipped untested. Three cases, and the third is the one that matters: a system
config naming no policy answers 'ask', not null, because parseSshGOutput fills the
OpenSSH default — and that distinction is exactly what the caller keys on. Null
means 'we could not look', which is the only state that keeps refusing unknown
hosts; a successful read that sets nothing clears the blindness without relaxing
anything, since strictestHostKeyChecking leaves the user's value alone against
'ask'.

I expected null there and was wrong about my own code; the test now records the
behaviour rather than my assumption. Also pins that the probe passes the null
device and terminates its args with -- so a host starting with '-' stays a host.

* fix(ssh): three release blockers from the readiness review

P1-1 was my own fix from the previous round, and it was wrong. I claimed
`ssh -G -F /dev/null` reads the system config while excluding the user's. It does
not: -F excludes /etc/ssh/ssh_config too, which sshGArgsForHost's own comment says
and I quoted before contradicting. Confirmed live against OpenSSH 10.2p1 — plain
`ssh -G` reports the sendenv lines from /etc/ssh/ssh_config, `ssh -F /dev/null -G`
reports none. So the probe returned built-in defaults on every machine, the
fail-closed guard never engaged, and a site-wide StrictHostKeyChecking yes was
silently ignored while we accepted AND durably recorded a key the user's own ssh
refuses. That is worse than the lockout it was meant to fix.

There is no ssh-only way to ask this, so the file is read directly — and the
question asked is deliberately weaker than "what is the policy". Anything
ambiguous (unreadable, an Include that will not resolve, the directive present at
all) answers yes and the caller stays fail-closed. Only a site config that
demonstrably says nothing about host keys clears it, which is the common case that
was being punished. Includes are followed, since macOS and most distros ship
`Include /etc/ssh/ssh_config.d/*` and missing that would read as "no policy" on
nearly every machine that has one. strictestHostKeyChecking goes with it: there is
no separately-read site value left to merge.

P1-2. `ssh -G` prints UserKnownHostsFile unquoted and space-separated even when
the config quoted it — verified the same way. One path containing a space is
therefore indistinguishable from two, and splitting shreds
C:\Users\John Doe\.ssh\known_hosts into fragments that resolve to nothing. Every
fragment misses with ENOENT, which reads as "absent" rather than "unreadable", so
the user appears to know no hosts and a CHANGED key is accepted as first contact.
The filesystem is the only thing that can disambiguate, so it decides: if no
fragment exists but the rejoined path does, it was one path. A list where any
fragment exists is a genuine multi-file config and is left alone.

P1-3. oxlint is a PR gate and this diff failed it on two lines. Both fixed —
including by splitting the replay on ESC rather than matching it, which is
equivalent since every private-mode sequence begins right after one, and respects
no-control-regex instead of suppressing it.

That gate failure is on me twice over: I reported LINT clean repeatedly while
filtering oxlint's output with a grep that could never match its
`path:line:col: error` format. Verification is by exit code now.

5183 tests pass; each fix has a test that fails without it.

* fix(ssh): the readiness review's P2s

P2-1. activeRepoId and activeWorktreeId could describe different workspaces. The
repo followed the host while the worktree came from local state, and it split in
exactly the case the preservation exists for — "the host named no worktree" is
precisely when it can still name a repo. All three active-* fields now derive from
whichever worktree won, rather than each picking a source. The nested ternaries
that hid it are gone.

P2-2. The trust-source reads sit AHEAD of client.connect, and readyTimeout only
covers the handshake — nothing wrapped attemptConnect. A home directory on a
stalled NFS or SMB mount made readFile hang forever, leaving the connection wedged
in `connecting` with no ladder entry and no recovery. Bounded at 5s, reusing the
existing withTimeout helper. The fallback is the one an unreadable file already
produces — evidence withheld, connect as ssh does but record nothing — not the far
worse "no hosts known" that would let a changed key through as first contact.

That helper absorbs rejections into its fallback, so the store's catch had to move
INSIDE the timeout; wrapping the other way silently swallowed the warning that is
the only signal the store is unwired rather than merely slow.

P2-4. doSsh2Connect runs up to five times per attempt as the credential ladder
advances, and each run re-read every known_hosts file, re-read the store, and
re-scanned the system config. Nothing writes those while a handshake is in flight,
so they are read once per attempt — which matters more now that each read can cost
up to 5s. Keyed by connect generation rather than cleared, so a superseded attempt
can never hand its sources to the live one.

P2-3. forgetHostKey was exported, tested and referenced by nothing. The
store-mismatch rejection now names the store file, so the case it was meant to cure
has a cure without it; an exported API nothing can reach is unverified in
production. Removed until D5 ships its UI, and the doc says so.

P2-5 needed no change: the site-policy branch it called dead is reachable again now
that the probe reads the real config.

The design doc drifted from the code in the two places this review checks, and both
are corrected: revocation now propagates for the ordinary rotation because a
known_hosts match is decided first, and the -F blindness is resolved by reading the
file rather than by refusing.

* fix(ssh): rejoin a spaced known_hosts path even beside an ordinary one

The whole-list check only fired when NOTHING in the reported list existed, so a
config naming both a spaced path and an ordinary one kept the spaced one in
fragments — the ordinary path existing was enough to leave it alone. The file the
user actually verified their hosts in then never got read, which is the same
failure the rejoin exists to prevent, just harder to notice.

Longest run first now: the longest sequence of tokens that resolves to a real file
is taken as one path and the scan continues after it, falling back to the single
token when no run resolves. A genuinely absent path is still reported as-is rather
than invented.

The mixed case fails against the previous version.

* test(ssh): pin the site config scanner's edge cases

This control decides whether an unknown host is refused when we cannot see the
site policy, and my first attempt at it was a security regression, so the cases
that decide 'policy present' deserve to be written down rather than assumed.

Seven, and each could have gone the wrong way. A commented-out directive must NOT
read as a policy or the lockout returns for every distro shipping the line
commented. A directive inside a Host or Match block MUST read as one, because no
attempt is made to evaluate whether the block applies — guessing wrong in the
permissive direction is the failure that matters. The equals form counts;
StrictHostKeyCheckingExtended does not. A nested Include is followed, since a
policy one level down is still a policy. An Include cycle terminates and answers
false, which is knowledge rather than doubt: both files were read in full and
neither mentions it.

All seven passed as written, so this pins behaviour rather than fixing it.

* test(ssh): assert tab survival, record the reattach gap rather than flake on it

Running the two SSH e2e specs — which neither review executed — showed the
tab-destruction spec failing on liveness three times out of three. The screenshot
disproved the obvious reading: the marker was on screen, echoed by a live shell.
getTerminalContent resolves the store's active tab id and returns '' when
paneManagers has no entry under it, which is indistinguishable from 'the shell said
nothing', and across a reconnect those two disagree.

Scanning every mounted pane instead fixed the read, and then measured the real
thing: three runs in four. The tab survives every time; the reattach behind it does
not. So the merge fix is real and incomplete — the store keeps the tab, the tab bar
renders it, and the pane sometimes never rebinds, which is the frozen-tab shape the
original report described, one layer down from the deletion that used to cause it.

Asserting that would put a one-in-four flake into the lane built to catch this
class, and a lane nobody trusts is how the original silent-skip failure happened.
So the spec asserts survival, which is deterministic at five runs in five, and the
liveness gap is written down in docs/reference/ssh-reconnect-source-recovery.md
with the first place to look.

* fix(ssh): stop an unreadable host key store from wiping every pinned key

Second readiness pass, checking each of the first pass's ten fixes rather than
taking them on trust. Nine held. This is the one that did not, plus three
fail-open shapes in the site-config scanner that a live OpenSSH disproved.

P1 — the store. loadTrustedHostKeys returns [] for ANY read failure, and
trustHostKey then wrote [...that empty list, newRecord]: one transient EMFILE
followed by one first-contact accept replaced the file with a single record.
Every other host re-TOFUs, and one whose key genuinely changed in between is
accepted as first contact rather than refused — the exact outcome pinning
exists to prevent. It also contradicted the doctrine this PR applies to
known_hosts two files away, where a file that exists and refuses to open is
evidence withheld.

Fixed by classifying one read instead of guessing twice: readStore returns
ok/absent/withheld, the read path flattens withheld to 'nothing trusted' so it
still fails closed, and the write path declines. That subsumes the separate
newer-version probe, so trustHostKey now reads the file once inside the queue
rather than twice. The 'Trusted host key' log moved inside the branch that
actually writes — it was already claiming success on the newer-version path.

P2 — the site-config scanner documents 'doubt wins on every path' and had
three where it did not, each the same shape: a path resolved WRONG still
resolves to something, and a nonexistent Include reads as 'nothing there',
which is indistinguishable from 'no policy'. Verified against OpenSSH 10.2p1:
relative Includes resolve against a fixed dir, not the including file's, so a
directive two deep was missed; ? and [...] are globs it honours; ~ and %-tokens
expand before use. All three now answer doubt.

P2 — credential prompts are gated on the attempt generation in one place
rather than per rung. A superseded attempt is denied without a recorded
decision, so isHostKeyVerificationError reads false and the ladder ran on to
prompt for a passphrase nobody was waiting on.

P2 — resolveKnownHostsFiles is async. Its rejoin existsSync-scans the very
paths the 5s bound protects, and sat outside it as an eagerly-evaluated
argument, so a stalled NFS/SMB mount blocked the whole main process.

Tests fail against the pre-fix code: 2 for the store wipe, 3 for the scanner.

Also: the 4 IME failures I previously reported as pre-existing main breakage
were a stale node_modules — the xterm patch from #14758 was not applied here
(402,643 bytes installed vs 403,181 expected). pnpm install applies it and all
4 pass. The OSC8 and SFTP failures were the same cause.

* fix(ssh): make the merge non-duplicating, and close the last scanner hole

Third readiness pass. Three P2s, all fixed.

The merge one is the one I most wanted a verdict on, and it is real: hostUnknown
filtered against ids the HOST knows and never against ids this same merge had
already emitted, so a tab id local state holds under two worktrees was re-added
under both. Two panes then share one terminalLayoutsByTabId entry and one
remoteSessionIdsByTabId entry — one remote PTY — plus an activeTabId that never
converges, which is the self-retriggering repair loop active-tab-owner-worktree
.ts exists to mitigate (React #185).

This PR does not create that state. It used to DESTROY it, by deleting every
local tab under a replaced worktree, and keeping live panes cost that accidental
cure. So the guarantee is made explicit rather than incidental: the merge now
never emits one tab id twice, whatever it is handed. The active worktree is
walked first so the surviving copy is the one the user is looking at, which is
the owner resolveActiveTabOwnerWorktreeId already prefers — merge and repair now
agree instead of each picking differently.

Scanner: an Include path that is quoted AND contains a space was split before it
was unquoted, so both halves missed and two absent paths read as 'no site
policy'. OpenSSH honours that form -- 10.2p1 applies an Include of a quoted
spaced path -- and it is likelier on Windows. Quote-aware splitting rather than
'any quote is doubt', because answering doubt for an ordinary quoted Include
with no space would reinstate the lockout this scanner exists to avoid. An
unclosed quote is doubt. Unquoted spaces still split, which is also what OpenSSH does.

The reconnect paint gate took the replay and re-scanned it, having already been
scanned by the caller that decides whether to fetch a snapshot at all — two full
splits of up to 100KB per pane per reconnect. It now takes the transition.
hasReplay is passed separately because it cannot be inferred: a replay with no
mode change and no replay at all both give null.

Tests fail against the pre-fix code for the merge and all four scanner shapes.

Correcting my own evidence claim from last round: of the two store tests, only
the wipe one fails pre-fix. The other guards the asymmetry the fix creates and
passes either way — worth keeping, but I should not have counted it.

* fix(ssh): honour every Include quoting form OpenSSH does

Fourth readiness pass. Two findings; one fixed, one deliberately not, with the
evidence for refusing it.

The tokenizer modelled double quotes only. A live 10.2p1 honours single quotes
and backslash-escaped spaces too, and both fell into the same silent fail-open
the double-quote case was raised for: fragments that resolve to nothing, and
'nothing there' is indistinguishable from 'no site policy'.

The escape is limited to a backslash before whitespace, NOT a general one. A
general escape would be catastrophic on the platform this most needs to be right
for: the Windows site config lives at C:\ProgramData\ssh\ssh_config, so it
would eat every separator in an Include beneath it and resolve to nothing --
reintroducing the fail-open it was meant to close. The test for that is
discriminating rather than incidental: it gives the file a literal backslash in
its name, so a swallowed separator resolves elsewhere and fails, where a plain
'expect false' could not tell the two apart. Verified it catches the naive
version, and that the other two catch the old tokenizer.

NOT fixed: the non-duplication guarantee still stops at the worktrees the merge
rewrites. A worktree that is neither replaced nor named by the host is never
walked, so a duplicate straddling that boundary survives.

Extending the guarantee to the assembly point was implemented and REVERTED. Any
rule there has to pick a survivor, and the ones available are wrong during a
worktree-id change -- which is the very thing that produces these duplicates.
Preferring the active worktree keeps the OLD id's copy at the moment a rename
lands, because the active worktree has not moved yet; the new worktree was left
with no tabs and its groups were never created.
remote-workspace-snapshot-duplicate-tab-repair.test.ts caught it, which is the
only reason I know the stronger version was wrong rather than merely bolder. A
surviving duplicate is mitigated by active-tab-owner-worktree.ts; deleting the
tabs of the worktree the user is about to land in is not. The comment now claims
only what holds, and says why it is not stronger.

Also records the exit from the isENOENT message-matching trade in
remote-wire-compatibility.md, where someone touching the relay error path will
be standing.

* fix(ssh): expand Windows OpenSSH's __PROGRAMDATA__ token in known_hosts paths

Captured real 'ssh -G' output from a Windows host rather than reasoning about
it, which is the one thing that could not be inferred from the POSIX format.
Two things came back that the code did not handle correctly, and one of them is
the security failure mode this work exists to prevent.

Native Windows OpenSSH prints the system paths with its own token UNEXPANDED:

  globalknownhostsfile __PROGRAMDATA__\ssh/ssh_known_hosts __PROGRAMDATA__\ssh/ssh_known_hosts2
  userknownhostsfile C:\Users\neil/.ssh/known_hosts C:\Users\neil/.ssh/known_hosts2

Passed through as a literal path, __PROGRAMDATA__\ssh/ssh_known_hosts misses
with ENOENT -- and an absent file is deliberately treated as 'no host is known
there' rather than 'evidence withheld', because that is the normal state. So a
site-managed known_hosts on Windows was silently invisible: every host in it
read as first contact, and one whose key an admin had rotated produced a TOFU
accept where it should have produced a mismatch. Now expanded from
process.env.ProgramData, and left literal when that is unset rather than
guessed -- a wrong path reads as absent, which is the very failure being fixed.

The second finding is reassurance rather than a bug: separators are MIXED within
one path (C:\Users\neil/.ssh/...), which Node's fs accepts on Windows, and a
spaced home prints unquoted exactly as it does on POSIX. So the space-rejoin
design is confirmed against the real format rather than assumed -- its
motivating example, C:\Users\John Doe, splits the way the rejoin expects.

The captured output is pinned as a literal fixture. Parsing and the rejoin are
pure string work, so this covers the input shape honestly off Windows; it does
not pretend to cover the platform's path arithmetic. The expansion test fails
without the fix.

Also confirms C:\ProgramData\ssh is the right site-config directory -- it
exists on the host, empty -- so the scanner is looking in the right place.

* fix(ssh): branch Include backslash handling on platform, both halves measured

Fifth readiness pass found that the previous narrowing traded one fail-open for
another. Both rules are right, on different platforms:

  POSIX 10.2p1:  Include conf\.d/x.conf     resolves as conf.d/x.conf
                 four backslashes needed to survive as one -- argv_split and
                 glob() each consume a level
  Windows:       Include C:\Users\...\x.conf  resolves, separators intact

So a backslash before an ordinary character ESCAPES on POSIX and SEPARATES on
Windows, and either rule applied everywhere fails open on the other platform.
Preserving on POSIX means looking for a path with a literal backslash, missing,
and reading 'no site policy'. Answering doubt on Windows means every absolute
Include is doubt, which is the lockout the scanner exists to avoid.

Now branched. POSIX answers doubt rather than emulating two rounds of glob
escaping for a question this coarse -- a backslash in a POSIX system config path
is vanishingly rare, so fail-closed costs nothing there.

The review offered the Windows half as a reasoned assumption and flagged it as
such. It is now measured on a real Windows host instead: backslash separators
resolve, AND an escaped space still escapes amid them
(C:\Users\neil\sshprobe\sp\ ace\x.conf -> port 2802), which is exactly the rule
implemented. Two other worries were checked and came back unfounded -- a
backslash-space inside EITHER quote is consumed by ssh, and a single quote
inside double quotes is an ordinary character, which the single quote-state
variable already reproduced.

The tokenizer takes the platform as a parameter, so both sides are pinned from
one host. Every expectation in the new oracle came from running a real ssh and
reading what it resolved to, not from reading source or shell convention -- the
tokenizer's whole job is to agree with ssh about which file it would read.

Also narrows an overclaiming comment: the dedupe set is consulted only by the
host-unknown filter, so a duplicate in the HOST's own snapshot still propagates.
Pre-existing and unchanged; the comment now says what the code actually does.

* fix(ssh): only expand __PROGRAMDATA__ when it is a whole path segment

Found by probing the expansion I had just written, rather than by reading it: a
bare startsWith also matches a path that merely BEGINS with those characters, so
__PROGRAMDATA__evil/known_hosts was rewritten to C:\ProgramData\evil\known_hosts
-- a directory the user never named. Same prefix-collision class I checked the
site-config scanner for and then did not check here.

Low reachability, since the token only appears because Windows OpenSSH emitted
it, and it emits it as a whole segment. Fixed because the expansion is one review
pass old and sits in the security path: a rewritten known_hosts path resolves
somewhere unintended, and a path that resolves to nothing reads as 'no host is
known', which is the fail-open this whole line of work has been closing.

Now requires the token to be the entire path or be followed by a separator --
both separators, since the path is Windows-shaped but may be parsed anywhere. The
test fails without the check.

* test(ssh): split the pty provider spawn tests into their own file

CI's static analysis went red on the merge of main: ssh-pty-provider.test.ts
reached 803 counted lines against a maximum of 800. Both sides contributed --
main grew the file and this branch added 7 lines to it -- so neither shows the
violation alone, which is why local lint stayed green until main was merged in.

AGENTS.md forbids disabling max-lines or bumping a per-file limit, and that rule
is right here: the file was doing two jobs. Spawn owns the startup contract --
ingress version, env scrubbing, execution ownership, and the reconnect races --
and is 630 of the 922 lines. It reads as its own unit rather than as an overflow
file, so it moves to ssh-pty-provider-spawn.test.ts and the shared relay stub
moves beside it under a name that says what it is.

Same tests, same count: 713 provider tests pass, and the line total is unchanged
across the two files.

* fix(ssh): remove the dead lint suppressions, and reach Terminal 1 in the restore spec

Two CI failures, both surfaced by this branch rather than caused by it.

Static analysis: the two no-require-imports suppressions on the ssh2 constants
require() are now unused -- main's config no longer reports that rule there --
and the changed-code audit treats a dead directive as an error. Removed; the
audit CI runs passes locally on the merge.

E2E: ssh-cold-activation-restore failed on clicking Terminal 1. This PR is what
routes that spec into the changed-e2e lane at all -- before, the Docker-SSH
specs only ran when someone edited a spec file, which is the gap this branch set
out to close -- so its first run in CI was here, and the failure is pre-existing
rather than new. The trace shows the cause: six restored tabs overflow the strip
at CI's window size and the restore pins it to the END, so Terminal 1 sits
outside the scroll viewport. Playwright's own scroll-into-view loses that race
against the sticky-to-end effect and times out on an element it can see but
never reaches.

The spec's intent is to activate the first tab and prove it remounted, not to
exercise strip scrolling, so it now scrolls the strip to the start first. Not
papering over a product bug: the strip is a native overflow container with
working arrow controls, so a user can reach the tab -- it is Playwright that
cannot drive a moving target.

Six specs pass locally in CI's exact order and worker count.

* test(ssh): press the restored first tab directly instead of waiting for it to hold still

The previous attempt swapped a click for scrollIntoViewIfNeeded and hit the same
30s timeout, which identifies the real cause: not that Terminal 1 is out of view,
but that it never holds STILL. Both APIs wait for the element to stop moving, and
the strip keeps re-laying-out while the relay reconnects behind it -- so both
time out on an element they can see and never settle on.

Driving the pointer directly needs no element to be stable, only to be somewhere
at the moment it is pressed, and the attempt is retried against the store rather
than believed. Activation is deferred to pointerup and suppressed past a drag
threshold, so it has to be a real down/up pair at one position -- a synthetic
click event would not select the tab at all.

Passes twice locally. The previous version also passed locally, so the honest
statement is that the local runs prove the interaction still works, not that they
reproduce CI's instability -- CI is the oracle for that.

Brennan Benson 619ee2cc90 fix(agent-hooks): detect IDS-truncated hook POSTs instead of failing open silently (STA-2870) (#14625) 2026-08-17 15:15:14 -07:00
Brennan Benson 5652fb7469 fix(codex): stop resuming a session under the wrong account when a sessions tree is locked (#15093)
* fix(codex): stop resuming a session under the wrong account when a sessions tree is locked

Two probes reported "this rollout is not bridged here" for any filesystem error,
not just a genuine absence:

- codex-session-resume-home.ts used existsSync on each ranked home's sessions
  directory. existsSync returns false on EBUSY/EPERM, so a briefly locked tree
  made the scan continue to the next ranked home — and the winning home becomes
  the resumed pane's CODEX_HOME, so it picks the account.
- codex-legacy-session-resume.ts caught every lstat failure for the selected
  account's candidate rollout and returned null, after which the caller kept the
  source per-account home.

Either way the session resumed under a different account's credentials while the
UI still showed the selected one.

Only a definitive ENOENT/ENOTDIR now means "not bridged here". Any other error
raises the typed temporary-unavailability refusal the ownership gate already
uses, which both PTY paths convert into a clean abort before spawn.

The refusal is scoped to the SELECTED account's home. An unreadable home that is
not the selected account cannot cause a wrong-account resume, so it is still
skipped rather than stranding the user.

These are pre-existing and independent of the STA-4422 ownership-marker failure:
they route to another account today with the gate uninvolved.

Fixes STA-4607

* fix(codex): refuse a resume when the selected sessions tree is locked mid-listing

Review found the first pass incomplete in two places, both the same category
error one layer further down.

The preliminary statSync on the selected sessions root was guarded, but the real
directory read happens later and listCodexSessionRolloutFilesIncrementally
swallows every opendir error. A lock held during enumeration — where nearly all
the I/O is, and so the far more likely case — still yielded nothing for the
selected account and fell through to another one. The listing now reports
directory errors through its existing onDirectoryError hook, and a
non-definitive error anywhere under the selected sessions root raises the typed
refusal. Non-selected homes and definitive absence still skip.

Separately, index.ts wrapped prepareLegacySharedCodexSessionResume in a blanket
catch and fell back to the source home, so the typed refusal from the candidate
lstat was swallowed and the resume still ran under the peer account's
credentials. That catch now rethrows ManagedCodexHomeTemporarilyUnavailableError
while ordinary migration failures keep warning and falling back, since a genuine
migration failure legitimately should not block a resume.

A typed refusal is only as strong as the narrowest catch between the throw and
the spawn. The frames between both throw sites and the PTY spawn were audited:
findTrustedCodexSessionResume, resolveCodexSessionResumeProvenance and
prepareCodexSessionResume have no catches, and the PTY layer already maps the
typed error before spawn.

Both fixes are mutation-checked. Disabling the listing hook makes the resume
resolve to the other account again; the index.ts rethrow is covered only by
typecheck, because src/main/index.ts has no unit-test entry point in this repo.

* test(codex): pin nested-directory lock coverage; document the resume repin contract

Review flagged the listing guard as matching only the exact sessions root, so a
nested dated directory would leak. It does not — the guard keys on the root being
listed, not the failing directory — but nothing pinned that. Added a test that
faults only sessions/2026/07/20 while the root stats fine; it fails under
mutation alongside the root case.

Also documented why the index.ts rethrow cannot fire today. That launch path pins
CODEX_HOME to the account that owns the rollout and deliberately refuses to repin
onto whichever account is selected now (#10793), so it does not wire the
selected-home resolver. The branch stays as a contract guard so the blanket catch
below can never silently swallow a typed refusal if that changes.
