Brennan Benson eb0ec39242 fix(runtime): stop one unreachable relay from freezing every workspace as active (STA-517) (#14649)
* fix(runtime): stop one unreachable relay from freezing every workspace as active

The worktree.ps liveness refresh is the only thing that retires an exited PTY,
and mobile renders "active" straight off the summary it produces. Its aggregate
inventory ran every provider through Promise.all with no per-provider deadline,
so a single SSH relay that rejected — or simply did not answer inside the 3s
budget, since a relay list runs to the mux's own 30s default — cost the runtime
the whole inventory. Nothing was ever proven dead, so every retained pane kept
reporting hasHostSidebarActivity/liveTerminalCount, and the SSH workspaces stayed
"active" on mobile for as long as the connection stayed unreachable.

Settle each SSH provider independently and forward the caller's deadline, so
local and healthy relays are still reconciled. A provider that does not answer is
unknown, not empty: the runtime's existing hasPty rescue keeps its panes. A local
failure still fails the aggregate, matching pty:listSessions.

The restored-orchestration-authority sweep now runs after that rescue, so a pane
the controller still vouches for keeps its handle instead of losing it to a
listing that merely omitted it.

STA-517

* test(runtime): assert the provider scope, not the exact arity, of inventory calls

These assertions exist to prove which provider scope the inventory asked for.
Forwarding the caller's deadline added a second argument, which broke them on
arity alone. Match the scope argument and require a numeric deadline beside it,
so the intent is preserved and the budget is covered too.

* test(runtime): type the inventory mock's scope parameter

A bare `async () =>` mock types mock.calls as an empty tuple, so reading the
scope argument off it fails typecheck. Declare the parameter the runtime
actually passes.

Neil 545b3fba08 refactor(shell): build every zsh startup wrapper from one shared builder (#15245)
* test(shell): pin every generated shell wrapper file with byte snapshots

Captures .zshenv/.zprofile/.zshrc/.zlogin, the bash rcfile, and the fish
init command for all three transports (local PTY, daemon/SSH, relay) so the
upcoming wrapper unification can be proven byte-for-byte identical.

* refactor(shell): build every zsh startup wrapper from one shared builder

Local PTY, daemon/SSH, and relay each had their own copy of the zsh
ZDOTDIR wrapper templates, and the copies had drifted. buildZshStartupWrapperFiles
now produces .zshenv/.zprofile/.zshrc/.zlogin for all three, with every
real difference expressed as a field on ZshStartupWrapperSpec.

No behavior change: the generated text is byte-for-byte identical for
every configuration, pinned by the snapshots committed in the previous
commit (captured from the pre-refactor generators).

Jinjing 7a695c70f1 test(e2e): harden triaged CI failures (#14656)
* test(e2e): harden triaged failures

* test(e2e): ship relay bundle to reusable shards

* test(e2e): tolerate expected IPC closures in daemon shutdown

A normal client exit can close the IPC channel before the finish ack
lands. Distinguish this from real failures by checking error codes,
only throwing if forced cleanup occurred or the error is not an IPC
closure.

* rm doc

* test(e2e): return termination status from legacy close handler

- terminateLegacyCloseClient now returns a discriminated union indicating
  whether the process had already exited ('already-exited') or termination
  was actually attempted ('termination-attempted')
- Allows finishLegacyCloseClient to only set forcedCleanup when termination
  was genuinely needed, not when the process exited cleanly on its own

* test(e2e): fix dispatch contract and voice mic locator

Point the release E2E contract at the renamed build step, and assert the
relabeled microphone through the Voice pane combobox even when Radix
leaves the listbox open.

* test(e2e): add contract test for relay artifact dispatch

Validate that the relay artifact built in CI is properly uploaded,
downloaded, and passed via ORCA_RELAY_PATH to E2E test runs.

* Distinguish between terminated and already-exited processes

Detect when processes have already exited instead of always reporting
termination success. Return booleans from cleanup functions to indicate
whether they actually signalled a process, catch tree-capture failures
when the root process exits before recording completes, and use these
signals to return accurate exit status from termination handlers.

* test(e2e): stabilize file creation and voice microphone tests

Use stable locators (aria-autocomplete, named triggers) and add retry
logic to handle file scans and device events that can interfere with
listbox state. Increase timeouts to allow async operations to complete.

* Add retry logic for transient GitHub API errors in PR body updates

GitHub API occasionally returns transient 5xx errors. Retry up to 3 times
with exponential backoff (1s, 2s, 4s) to improve reliability during
temporary service disruptions. Export updatePullRequest and add sleepImpl
parameter for test injection.

* Add tab search result retention during typing

Keep search results on screen while the deferred query catches up with
the live query. Re-validates results against the current input without
dropping rows prematurely, ensuring the user can select from what they see.

* Add proper types to tab search mock

Replace `unknown` with concrete types (`OpenTabSearchResult`,
`OpenTabSearchEntries`, `SearchableWorkspaceTab`) and use type guards
for discriminated unions to improve test type safety.

Neil 640e8a4322 test(updater): await the linux install re-proof instead of budgeting turns (#15246)
`settleQuitAndInstall` gave the pre-install digest re-proof a fixed budget of
40 real event-loop turns. That budget is wall-clock, not work: the re-proof
does two realpaths, an lstat and a streamed sha512, and on a loaded CI runner
those outlast ~40ms of setTimeout(0) turns. When they did, the test asserted
early and its unfinished install continued inside the *next* test — against
the same mock singletons, since `vi.resetModules()` only affects later
imports and leaves the old module instance running. Hence the reported pair:
one case missing `post_commit_cleanup_failed`, the next seeing killAllPty
called twice.

Wrap `revalidateLinuxPackageForInstall` for every test in this describe (the
wrapper delegates to the real implementation, so artifact state stays real)
and await the promise it hands back, then drain again in `afterEach` so no
re-proof can outlive the test that started it. `holdRevalidation` folds into
the same probe as an opt-in mode.

The turn loop stays as slack for microtask-only tails, but is no longer
load-bearing: with the loop set to zero turns the suite still passes, where
before the fix 11 of 19 cases failed with the reported assertions.

Neil 9b1f0373eb fix(relay): scope shell history for Windows -> WSL panes (STA-4682) (#15236)
`injectRelayHistoryEnv` matched only bash*/zsh*, so a relay pane launched
through `wsl.exe` got no HISTFILE at all and every WSL worktree shared one
global history.

The history file stays on the relay host under the existing flat root, so
`deleteRelayHistory` remains the deletion counterpart unchanged; only the
exported path is translated to drvfs for the guest, and WSLENV carries it
across the boundary.

Guest fish stays out of scope on purpose: its history file lives inside the
distro, where the relay has no deletion path.

Neil 2b057eb21e fix(terminal): end a url at CJK punctuation instead of swallowing it (#15240)
Terminal URL detection treated every non-ASCII character as part of the
url, so Japanese or Chinese text written straight after one was absorbed
into the link. A line like

  PR: https://github.com/org/repo/pull/12345(作成済み・マージ待ち)

underlined the whole run and opened the annotation percent-encoded onto
the end of the url, which 404s.

The body terminator listed only ASCII codes, so nothing at or above 0x80
could end a url.

Terminating on all non-ASCII is the obvious repair and is wrong: a url
path may legitimately carry unencoded CJK, and the wrapped-url tests
cover exactly that - a real multi-line url whose continuation row is a
Chinese path segment. That repair was written first and broke four of
them.

The distinction is punctuation, not ASCII. Non-ASCII punctuation,
symbols and separators end a url; letters do not. Full-width brackets,
an ideographic space, a full-width comma and the katakana middle dot are
prose; 文档 in a path is not.

Adds the extraction test file the module never had, covering the
reporter's three cases, the CJK-path case that must keep working, and
ASCII behaviour as a regression guard.

Neil 41ab3b825a ci: run the IME e2e suite when terminal input code changes (#15239)
PR e2e only runs specs whose own spec file changed, plus two explicit
source-to-spec mappings. Neither covers the terminal pane or the xterm
patch, so every terminal IME fix in the 1.4.18x window shipped without
triggering a single e2e spec - including one whose diagnosis was later
refuted by hardware, and one that turned out to fix a different bug than
it claimed.

The suite it skipped is not thin. It drives real compositions over CDP,
reads real pty bytes, asserts real overlay geometry, and exercises the
macOS-only input path on Linux runners through a user-agent policy
override. It simply was not pointed at the code it covers.

The SSH block immediately above records the same lesson from the same
cause: "the Docker-SSH specs only ever ran when someone edited a spec,
so four pane-restore regressions shipped from SSH source edits that
touched no test." This applies it to terminal input.

config/patches is included because the terminal's composition and key
handling live in the xterm patch, so a change there is exactly the kind
this suite exists to catch.

Verified by replaying the filter against the merges that skipped it:
15218, 15223 and 15198 each now select six specs.

Neil 9a41119a99 feat(crash-reporting): read-only Windows install-dir DACL probe breadcrumb (#15107)
* 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 d143922561 fix(terminal): deliver an IME commit the deferred textarea diff missed (#15198)
Picking a single Chinese character from the candidate window with a
number key loses it. The character flashes and disappears. Picking the
same candidate with the mouse works, and picking multi-character words
with number keys works.

Two paths can deliver an IME commit, and this falls between them. A
keydown the input method consumed routes into a setTimeout(0) diff of
the helper textarea, and that diff is what normally delivers the commit;
xterm's _keyDownSeen guard exists to defer to it. When the commit
arrives after that timer has already run, neither path delivers. Mouse
selection works because no key is down, and a real composition session
works because it takes a different path entirely. That narrows it to an
input method whose commit round-trips asynchronously and which shows no
in-application preedit.

Track that a consumed keydown still owes its commit, and deliver only
when the diff did not. The upstream guard and its single read site are
untouched, which is what keeps the duplicate-commit behaviour it was
added for sealed.

Not doing the obvious repairs deliberately: clearing the flag, skipping
it for keyCode 229, or setting it after the composition short-circuit
each unblock the input path without retiring the diff, and all three
were measured emitting the character twice.

The patch and the lockfile hash here are generated. Review
config/patches/xterm-src/@xterm__xterm@6.1.0-beta.287.src.patch, which
is the hand-written source of the change; the shipped patch and both
minified bundles are the regenerator's output from the pinned upstream
build, so nothing in this change was hand-transcribed into a bundle.

Jinjing cdd3aabdd8 Display occupant agent icons in tab search results (#15134)
* Display occupant agent icons in tab search results

When searching for or viewing open tabs, terminal tabs now show the icon of their occupant agent (e.g., grok) instead of a generic terminal icon. This makes it clearer which tabs have agents actively running. The occupant resolution reuses the same logic as the tab-strip agent identity system, including support for launchAgent, hook status, sleeping sessions, and OSC title parsing.

* Simplify tab occupant agent resolution to use unified label only

Remove the recordTitle parameter and rely solely on the unified title,
which already carries live OSC titles. The terminal record's own title
can stay stale (e.g., "Terminal N") while the unified label reflects
the current state, eliminating duplication and simplifying the contract.

* Add occupantAgent field to workspace tab helper

Jinjing 314b02ba2d Redesign artifacts page as full-width table with drawer (#15233)
* refactor(artifacts): redesign as full-width table with detail drawer

- Artifacts list displays as a compact data table with columns (Name, Type, Size, Updated, Expires)
- Selected artifact opens in a right-side drawer instead of inline preview
- Search and refresh consolidated in top toolbar
- Better space utilization for browsing the artifact list

* refactor(artifacts,automations): extract shared list-table layout

- Extract common list-table styles (container, header, row) to @/lib for
  consistency across artifacts and automations tables
- Move row interaction utilities to @/lib/list-row-interaction for reuse
- Fix drawer width to calc(100vw-80px) to avoid macOS traffic-light controls
- Extract WINDOW_CONTROLS_WIDTH/HEIGHT constants so portaled surfaces avoid
  the Windows/Linux overlay without hardcoding pixels
- Clamp artifact search query to 2KB to prevent multi-MB pastes from pinning
  renderer memory
- Remove unused artifact list visual mock

* Extract shared artifact row actions and use CSS var for traffic lights

- Unify dropdown and context menu actions via artifactRowActions() to prevent
  them from diverging during future maintenance.
- Replace hardcoded 80px with platform-aware CSS variable
  (--mac-traffic-lights-width) so only macOS reserves space for traffic lights;
  Windows and Linux controls sit on the right edge instead.

Neil 598ba5d276 fix(terminal): stop the macOS IME forwarder from running on iPadOS (#15218)
* fix(terminal): stop the macOS IME forwarder from running on iPadOS

Korean typed into a terminal from an iPad web client arrives as loose
jamo instead of composed syllables.

The native-text forwarder is a macOS workaround: it claims a printable
keydown and delivers the input method's substituted text from the input
event alone. It stands aside for IME composition by checking isComposing
and compositionstart. Touch iOS/iPadOS is unreliable about firing those
for hardware-keyboard CJK input, so each jamo keydown is claimed as its
own one-shot substitution rather than deferred to xterm's composition
handling.

It runs there at all because every iOS user agent contains "Mac" -
"Macintosh" in iPad desktop mode, the default since iPadOS 13, and
"like Mac OS X" in mobile mode. maxTouchPoints is the only signal a
real Mac never sets. The Linux branch immediately below already makes
the mirror-image exclusion for Android and CrOS; the Mac branch never
got the same treatment.

Gate the forwarder install only. isMac keeps its other five consumers -
the Ctrl+C interrupt, clipboard bypass, JIS yen input and the standalone
229 keydown policy - which intentionally still treat an iPad with a
hardware keyboard like macOS, matching iPadOS shortcut conventions.

Without the forwarder, xterm's own composition path plus the deferred
textarea diff is the sole delivery mechanism, which is already the
arrangement on Linux.

Not verified on hardware: the claim that composition events are absent
on iPadOS is the mechanism the code supports and the only one matching
the reported symptom, but no on-device capture confirms it. The platform
detection stands on its own regardless.

terminal-ime-input-context-refresh.ts has the same user-agent collision
for its NSTextInputContext refresh. Narrower trigger surface, left for
a follow-up.

Refs #13345

* fix(terminal): require more than one touch point before skipping the forwarder

The gate used maxTouchPoints > 0, which is looser than the idiom already
in this repo. isIOSWebView in mobile/src/terminal/terminal-webview-html.ts
requires more than one, because a Mac with a touch-capable peripheral can
report exactly one, and such a Mac must keep the forwarder: it is a real
Mac running the input method this workaround exists for.

Under the old threshold that Mac silently lost native text substitution -
a macOS regression introduced by a fix aimed at iPadOS. A captured iPad
reports five, so the stricter bound costs nothing on the device this
targets.

The check stays user-agent based rather than adopting that helper's
platform check, because an iPhone reports platform "iPhone" rather than
"MacIntel" and would slip through.

Neil 49752477a6 build(xterm): restore the patch regeneration harness and gate it in CI (#15223)
* build(xterm): restore the patch regeneration harness and gate it in CI

docs/reference/ime-architecture.md says "Never hand-edit the bundles in
the patch" and links to docs/reference/xterm-patch-regeneration.md. That
doc does not exist, and neither does the harness it describes.

Both landed in 29117bf776 and were deleted by 17cfc968cf, a revert of
the composition-ownership change, which swept up a build tool and a CI
gate as collateral. The rule survived; its enforcement did not. Every
xterm patch since has had to hand-edit minified bundles to comply with
the surrounding architecture, because everything resolves to
lib/xterm.mjs at runtime and under vitest, so a src-only edit is inert.

The shipped bundles were therefore not the output of any build, and this
restores them to build output. Comparing identifier multisets against a
pristine build of the pinned commit finds hand-written names a minifier
never emits ($rl, $hp, $tid), const in an otherwise let-only esbuild
bundle, !! where the source reads Boolean(), an escaped LRM where esbuild
emits the literal, and a return block esbuild collapses to void(...).
Every remaining token difference is a minifier local reallocating.

The old source patch could not be reused. It described the reverted
composition-ownership architecture, so restoring it would have re-applied
an abandoned design on top of dropping three accumulated fixes. It is
re-derived from the shipped patch instead, and the derivation is a fixed
point.

Two deliberate departures from the deleted version. Sourcemaps are
included rather than deleted, because a live test reads lib/*.map and
asserts the mapped version matches the runtime version. The source-patch
superset carve-out is gone, so a source hunk the shipped patch cannot
name now fails loudly instead of being carved out silently.

The doc's claim that the webgl and serialize addons reproduce byte for
byte was half wrong. Their ESM output does reproduce at the pinned
commit, but both also publish CJS that the root package script never
builds, so folding either in needs a build step this harness lacks.
Recorded as a blocker rather than a confident sentence.

xterm_patch_sync runs the regenerator in --check mode, so a patch that
does not match a rebuild of the pinned upstream now fails PR CI.

The -diff -text attribute is required, not cosmetic: pnpm hashes the
patch byte-for-byte, so a CRLF checkout breaks the install outright.

Not verified: the CI job has not run on a real runner, the addon CJS
bundles are unreproduced, and the generator is untested on Windows and
Linux.

* build(xterm): make the regenerator runnable on Windows and drop dead paths

Readiness review on the restore found one blocking gap and two cheap
cleanups. None of them change the emitted patch, which is byte-identical
before and after.

The generator could not run on Windows at all. Three sites called npm
through execFileSync with shell:false, but npm ships as npm.cmd there,
execFile applies no PATHEXT, and since CVE-2024-27980 it refuses a .cmd
target without a shell. That matters because this harness arms a
blocking gate whose documented remedy is --write, so a Windows
contributor who tripped the gate had no remedy except hand-editing a 7MB
minified bundle, which is the practice the gate exists to abolish. Four
sibling scripts in config/scripts already handle this; the fix follows
them and lands in run(), so the manifest-driven build step is covered
too. git and tar are real executables in System32 and keep resolving
without a shell, which avoids quoting exposure on paths with spaces.

deleteGeneratedSourcemaps was unreachable, since the policy is include.
Deleting it left "delete" as a legal policy value that nothing honoured,
so a manifest asking for it would have silently shipped sourcemaps that
do not match the bundle. The enum is narrowed and an unrecognised policy
now throws rather than falling through.

generatedHunks moved into the test file rather than being dropped; its
partition assertion, that generated and source hunks reconstruct the
whole patch, is worth keeping.

The -text attribute now covers all five patch files. pnpm hashes each of
them byte-for-byte, so the CRLF hazard the xterm patch was protected
from applies equally to node-pty and the three addons. All five were
already LF in the object DB, so this pins existing behaviour. -diff
stays scoped to the xterm patch, since the others are readable.

The doc's claim that the addons reproduce byte for byte is now dated and
marked a one-off measurement rather than an invariant, because nothing
re-runs it.

Effective lines fall from 591 to 568 against the 600 budget. Still the
largest file in config/scripts, and adding a second package to the
manifest would need a split first.

Jinjing 63dbf12d14 Split github client (#15214)
* refactor(github-client): reorganize client into lifecycle folders

* refactor(github-client): extract PR refresh data and outcome assembly

Separate the derived data calculation and outcome assembly logic from
branch-lookup-resolution into dedicated modules for better separation of
concerns. Modernize type import syntax and format exports consistently.

* refactor(github-client): improve error handling and resilience

Defensive GraphQL parsing prevents partial responses from breaking REST fallbacks.
Cache failures now use shorter TTLs for faster recovery. PR operations have
dedicated error classification. GraphQL mutations track rate limit usage to prevent
quota exhaustion. Data validation improved to reject spurious values.

* Extract check rerun error classification with operation context

Create classifyRerunChecksError() to provide operation-specific error
messages when check reruns fail. This replaces generic GitHub error
copy with context appropriate to what the user attempted (rerun
checks). Follows the pattern of classifyListPrsError and improves
error handling by delegating extraction to extractExecError.

* Make check-rerun not-found error message resource-neutral

Error handling for failed check reruns now covers both workflow-run
reruns and standalone check-run rerequests. Tests verify the neutral
message works for both scenarios.

* fix(terminal-history): drop an inherited Orca fish_history (STA-4682)

fish EXPORTS `fish_history`, so an Orca launched from a fish pane keeps the
launching worktree's session name in process.env. Every fish pane of the nested
app then hit the check-before-set early return and wrote into that one
worktree's history file, in every worktree. Drop Orca-minted names (desktop and
relay prefixes) wherever the session is injected, and in the history-disabled
and daemon spawn paths; a genuine user value still wins.

* fix(relay): drop an inherited Orca fish_history on every spawn path (STA-4682)

injectRelayFishHistoryEnv runs only for a fish pane with history isolation
on and a worktreeId, so a relay that inherited an Orca-minted fish_history
kept it on every other path — scoping those panes to another worktree's
history file. The desktop drops it on both branches; scrub it in
buildSpawnEnv so relay spawn and revive match.

Also record why injectWslFishHistoryEnv keeps its own drop (redundant with
both current callers, kept as the function's precondition).

Neil e39def3825 fix(repo-identity): bound git remote-identity probes and retire them with their repo (#15196)
* fix(repo-identity): bound git remote-identity probes and retire them with their repo

The local `git remote -v` probe ran with no timeout and no signal, and the
runner only arms its kill timer when a timeout is passed, so a hung NFS/SMB
cwd or a wedged `wsl.exe -d <distro>` left the promise unsettled and the child
alive. Because the sweep is sequential and dedupes per location, that one
wedged location stalled enrichment for every other repo.

- probeGitRemoteIdentity/detectGitRemoteIdentity take `{ signal, timeoutMs }`;
  local reads get the 5s background local-git-read budget, SSH gets a budget
  under the relay's 30s request timeout. Timeouts/aborts still map to
  `unavailable`, never `no-remote`, so they cannot clear a resolved identity.
- In-flight probes are tracked with an AbortController and retired (aborted +
  dropped) when their location is no longer backed by a repo, so a re-added
  repo is not poisoned by the dead entry and a retired probe cannot re-seed a
  retry deadline.
- Added the missing sweep-level guard so repos:list / projects:list /
  projectHostSetups:list coalesce into one pass instead of stacking one
  sequential sweep per list IPC.

STA-4452

* refactor(repo-identity): bound the enrichment listener set to stable caller references

Every call site allocated a fresh onChanged closure, so the Set that notifies
coalesced sweeps deduped nothing: during a chain that never quiesces it grew one
entry per list IPC and multiplied the repos:changed broadcast. Hoist the closures
to stable references in ipc/repos.ts and OrcaRuntimeService, and state the
contract on the set.

Also: guard the synchronous retirement call so the fire-and-forget entry point
keeps its no-throw contract, drop the placeholder promise in favour of building
the in-flight entry in one shot, and make the coalescing test use a shared list
reference plus a distinct runtime reference so it detects both stacked passes and
a dropped caller.

`onCreateCancellationFailure` fired on ANY rejection of the `cancelCreateOrAttach`

`DaemonConnectionLostError`. A refused or timed-out cancel falls back to the
existing bounded `unmatchedCancelGraceMs` wait and then rejects just its own request.

Also wraps the control-socket write so a synchronous throw drops the pending entry
and its timer instead of leaking them.

STA-4663's premise — that legacy daemons reject `cancelCreateOrAttach` as an unknown
request type — is incorrect; the handler has existed since protocol v11 (181741d769).

* fix(daemon): keep the wedged-daemon respawn signal when a spawn cancel times out

STA-4663 stopped a failed cancel from tearing down the shared connection, but
with it went the only path that recovered a daemon wedged with its socket still
open: create times out at 30s, its cancel times out at 5s, and nothing else in
the client ever notices.

Classify our own deadline as DaemonRequestTimeoutError. When the request and its
cancel both hit it, reject that request alone with the message isDaemonGoneError
matches, so withDaemonRetry respawns instead of retrying forever. Siblings are
untouched, and aborts are excluded — the caller asked to stop, not to retry.

Neil 3697d68f21 fix(cmd-j): decline a GitLab iid match when the repo remote names a different project (STA-4450) (#15193)
* fix(cmd-j): decline a GitLab iid match when the repo remote names a different project (STA-4450)

`repoMatchesGitLabSlug` laundered a definite project-path mismatch into
`'unknown'` whenever the resolved identity came from a remote named
`upstream`, and `worktreeMatchesGitLabUrl` treats `'unknown'` as permission
to accept a bare iid. Since `deriveGitRemoteIdentity` ranks `upstream` above
`origin`, any repo whose top-ranked remote is `upstream` lost GitLab project
gating entirely, so an exact URL for an unrelated project could surface that
workspace.

Return the `matchGitRemoteKeyParts` verdict directly. Resolved identities are
re-probed on a 6h TTL, so a remote naming a different project is current
evidence. `'unknown'` now means only "no identity" or "unexpanded SSH host
alias", both of which stay permissive as before.

* docs(cmd-j): correct the identity-freshness comments and drop a duplicate test

The GitLab why-comment implied resolved identities refresh unconditionally.
They only refresh when a repo/project list sweep finds one past its ~6h TTL
(`selectEnrichmentCandidates` runs from `repos:list`/`projects:list`/
`projectHostSetups:list`, four refreshes per sweep, after a 5m startup delay);
there is no background timer. State the accepted cost instead of implying the
gate is loss-free.

The GitHub-side comment still claimed the identity is "chosen when the repo
was added and never re-probed" — the exact claim this PR disproves. Rewrite it
to the reason that still holds (one stored remote hides a fork's `origin`).
Behavior on the GitHub path is unchanged; it stays with the twin ticket.

Delete `does not surface an upstream-identified repo for an unrelated project
iid`: the inverted test above it already asserts both halves (mismatched
project declines, the named project still matches) against the same
upstream-derived identity.

Neil 13b10e0b54 ci: cut PR wall clock by caching what CI recomputes every run (#15211)
None of these change what CI checks — they remove work the runners
repeated on every PR.

- install-node-dependencies installed with --no-frozen-lockfile, so every
  job re-resolved the graph against the registry to recompute what the
  lockfile already pins. Measured at ~62 MB of packument metadata per job;
  the pnpm store cache does not cover the metadata cache, so this was paid
  ~39 times per run. The `git diff` guard that made the re-resolution
  redundant stays.
- --ignore-scripts leaves node-pty with no build/Release, so
  ensure-native-runtime node-gyp-compiled it in every job asking for a
  runtime. Cache the build under an ABI-bound key (runtime, resolved Node
  version, node-pty patch) with no restore-keys, since a partial match is
  exactly the mismatched build that would be recompiled anyway.
- The four fetch-depth: 0 checkouts pulled full history including every
  historical blob (blobs are ~89% of this repo's pack). They only need the
  commit graph for a merge-base diff, so fetch them blobless. Measured
  30-43s each today versus 8s for the shallow checkouts. One of them,
  e2e-paths, gates the entire E2E chain.
- E2E jobs ordered setup-node before pnpm, which meant setup-node could not
  find the store and no E2E job cached dependencies at all. Reorder and
  cache; this sits on the critical path in both the build job and each
  shard.
- git_compatibility rebuilt Git 2.25.5 from a pinned tarball on every PR.
  Cache the build; the sha256 assertion still guards the miss path.
- typecheck ran three independent tsc passes back to back and discarded the
  .tsbuildinfo each project already emits. Run them concurrently and cache
  the incremental state.
- package (windows) built the electron-vite targets serially via
  build:release. Use a :parallel variant that overlaps them, matching what
  the Linux package job already packages and smoke-tests from.

Contract tests cover each new cache's ordering and key so none of them can
silently start serving a stale or ABI-mismatched artifact.

Neil f8e728bb8b fix(watcher): watch the resolved worktree root so symlinked and differently-cased paths work (#15077)
* fix(watcher): keep macOS FSEvents paths under the subscribed worktree root

macOS FSEvents reports OS-canonical paths: symlinks resolved and every
directory in its on-disk spelling. Linux (inotify) and Windows both rebuild
event paths from the directory that was subscribed, so only macOS observes
the mismatch.

Orca's watcher contract is "event paths live under worktreePath". Consumers
derive a worktree-relative path with relativePathInsideRoot(), which returns
null when the event falls outside the root -- and a null relative path drops
the event silently. So on a Mac whose worktree or folder path traverses a
symlink (~/code -> /Volumes/..., anything under /tmp or /var), or is spelled
with different casing than disk on a case-insensitive volume, every watcher
event was discarded: the editor never reloaded an agent's edit, the File
Explorer never refreshed, and Source Control never re-ran status. Nothing
errored, which is why this looked like "the file watcher stopped working"
on some machines and not others.

Rewrite event paths back onto the subscribed root inside
subscribeThroughWatcherSupervisor -- the single boundary every desktop,
runtime-environment, and SSH-relay watch passes through -- so one change
covers all three transports.

The resolution runs alongside the subscribe rather than before it: an await
ahead of the subscribe call lets a caller's abort land in a window where no
watcher-process subscription exists to cancel, which hangs the existing
cancellation contracts. The subscribe promise settles only after the rewrite
is installed, and only after the subscription itself is recorded, so
teardown never waits on a realpath.

Matching folds per path segment (NFC + case) instead of by prefix length,
because both folds change length and a folded-prefix length would slice the
raw event path mid-character. Byte-exact fast paths run first, so unaliased
roots -- every Linux and Windows watch, and most macOS ones -- cost one
string comparison per event and allocate nothing.

* fix(watcher): watch the resolved root so symlinked worktrees work on Linux too

Verified on a real Linux host: @parcel/watcher passes IN_DONT_FOLLOW |
IN_ONLYDIR to inotify_add_watch, so a symlinked worktree root fails outright
with ENOTDIR ('Not a directory'). The watch never installs and Orca caches the
root in unwatchableRoots, so it is never retried for that session. That is a
worse symptom than the macOS path-spelling mismatch and hits Linux users of
symlinked checkouts on every machine.

Hand the backend the resolved directory instead of the caller's spelling, and
keep mapping delivered paths back. Resolving the root also lets
@parcel/watcher's own ignore paths match again on macOS, where they were
computed from the unresolved root and silently excluded nothing.

The resolve is synchronous on purpose. Every caller reserves and forks its
watcher child in the same tick as the subscribe call -- capacity accounting and
cancellation ordering both depend on it, and 30+ existing tests encode it -- so
an await here would open a window where a subscribe is issued but no
cancellable child exists.

* test(watcher): use a directory junction on Windows so the alias repro runs there

Creating a directory symlink on Windows needs elevation or Developer Mode, so
the alias tests failed with EPERM on a real Windows host. A junction needs
neither, is what users actually have (a junctioned C:\dev), and realpath
resolves it identically -- so one fixture now covers all three platforms and the
end-to-end repro no longer skips outside Linux and macOS.

* test(watcher): pin the fabricated-path failure modes of the root rewrite

A rewrite that returns a WRONG path is worse than no fix -- a consumer would
act on the wrong file -- so pin the cases that could produce one: sibling
directories that share a prefix with the root (POSIX and UNC), the root itself
versus a shorter path, drive-letter casing, a root-only canonical path, and a
script where toLowerCase changes length. Found by running the rewrite over an
adversarial table; all already passed, so these lock in behaviour rather than
fix it.

* docs(watcher): drop an unverified claim about ignore paths

I claimed resolving the root also repairs @parcel/watcher's ignore-path
matching for aliased roots. Probing it on macOS shows the node_modules write is
excluded either way: FSEvents resolves symlinks in its own exclusion paths, so
the daemon filters at the source regardless of which spelling we subscribe with.
On Linux the exclusions are userspace globs relative to the watched directory
and there was no watch at all before this change, so there is nothing to
compare. Removing the claim rather than leaving a plausible-but-wrong rationale
in the module header.

Brennan Benson 6ee265e579 feat(agent-status): surface the model each Codex subagent is running (#8251) (#14627)
Codex child rows have carried a model field end-to-end since #9637, but the
transcript reader never populated it, so every transcript-discovered child
rendered with an empty model chip. Read the child's own turn_context.model
from the rollout records already fetched for completion detection, so the
sidebar can distinguish an orchestrator model from a subagent model.

No added file I/O and no added rows: the model is parsed from records the
reconcile pass already read, and both row components already render
entry.model.

Every CJK byte-exactness spec in the suite types a handful of characters, so

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.

* 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 BensonandBrian Dai 15efc87e35 fix(agent-hooks): bind agent status to the pane its session was spawned into (STA-2069) (#14615)
* fix(agent-hooks): bind agent status to the pane the session was spawned into (STA-2069)

Claude Code >= 2.1.206 hosts TUI sessions as workers under a shared daemon,
and the daemon forwards only its own allowlisted env — so hook posts carry
whichever pane first started the daemon, not the pane the user is in.

Pin a minted --session-id at spawn where Orca still knows the pane, record
sessionId -> pane, and correct the posted key at both hook ingest seams.

Co-authored-by: Brian Dai <43929761+BrianDai22@users.noreply.github.com>

* fix(agent-hooks): pin the session id in root-option position, not appended

Appending `--session-id <uuid>` broke every `claude <subcommand>` launch:
`--session-id` is a ROOT option, so `claude mcp list --session-id <uuid>`
exits with "error: unknown option '--session-id'". Splice it immediately
after the executable token instead, which is valid for both a bare session
and a subcommand, and is already before claude's own `--` terminator.

Also write the binding-key separator as an escape rather than a raw
NUL byte, which made the file a binary blob in git.

Close three hunks that no test could fail on: the pty.ts spawn call site
that records the binding, the relay seam's worktreeId override, and the
already-correct-pane early-return that suppresses a worktree restamp.

Brennan Benson 9f4ea42493 fix(agent-status): say what an OpenCode permission request is waiting on (STA-3160) (#14614)
* fix(agent-status): say what an OpenCode permission request is waiting on (STA-3160)

A permission.asked arrives as hook_event_name PermissionRequest, but
extractOpenCodeToolFields had no branch for it, so the pane reported a bare
{state:'waiting'} with no tool or command. The user could see that OpenCode was
blocked but not on what.

Read the fields @opencode-ai/sdk fixes for EventPermissionAsked: 'permission'
names the request, and metadata/patterns carry the command or paths it covers.
The normalizer is shared with mimo-code, so both are covered.

* fix(agent-status): show the OpenCode permission on the row, and retire it after (STA-3160)

Live validation against opencode 1.18.18 showed the original change populated
toolName/toolInput on a `waiting` entry that no surface rendered, while leaving
the answered permission cached for the rest of the pane's session.

Retire the tool fields on every OpenCode-family event except PermissionRequest.
isNewTurnEvent is false for this family, so resolveToolState otherwise inherits
one answered permission onto every later frame and the row reads a resolved
command as the live tool. Reproduced end to end: after approving `rm -rf build/`,
an unrelated later turn still reported it.

Read `filepath` from permission metadata. The SDK types metadata as
Record<string, unknown>, so its keys come from each tool; a live opencode 1.18.18
sends `filepath` (one word) for `edit`, which the previous key list missed. The
fallback to `patterns` covered it by accident, and the test that claimed to cover
it used `metadata: {}` — a shape OpenCode never emits. Tests now use captured
payloads for bash, edit and webfetch.

Show tool fields on `waiting` as well as `working`. All three consumers gated on
`working`, so a permission request rendered nothing at all; before/after of the
sidebar was pixel-identical. The rule now lives in one place (showsAgentToolPreview)
because a gate duplicated across three surfaces is a gate that drifts.

Brennan Benson 8cd338357e fix(runtime): tear down terminal subscriptions only through their owning registration (#14992)
* fix(runtime): tear down terminal subscriptions only through their owning registration

A terminal.subscribe teardown was keyed on `${terminal}:${clientId}`, which is
stable across reconnects. cleanupSubscription invokes whichever cleanup currently
owns that key, so after a mobile reconnect rebound the id, a late teardown from the
dead connection killed the replacement stream and the terminal froze (STA-4510).

Add registerOwnedSubscriptionCleanup, returning a registration handle whose
releaseIfCurrent no-ops once the id has been rebound, and route all 12 teardown
call sites in the three terminal.subscribe branches through it. Register-time
eviction now also targets the owner it captured rather than re-resolving the key.

terminal.unsubscribe gains the same ownership rule via connectionId, matching the
runtime.clientEvents.unsubscribe precedent: make-before-break migration sends the
unsubscribe over the old session after the new one has already rebound the id.

The teardown-by-key pattern predates the bug; #7490 made it reachable by binding
the exit-waiter to the per-socket abort signal, so every socket close now runs it.

Tests use a faithful subscription-registry double; the ad-hoc Map stubs they
replace never evicted the prior generation, which is why no test caught this.

* test(runtime): migrate the remaining subscription stubs to the faithful registry

streaming.test.ts and terminal-provider-snapshot-sequence.test.ts still stubbed
registerSubscriptionCleanup only, so terminal.subscribe's owned registration was
undefined and teardown never fired. Assert the registration is retired rather than
spying on cleanupSubscription, which the owned path now calls internally.

* fix(runtime): guard the lease-only presence release and use the shared registry double

Review findings on this PR:

- The lease-only branch's compensating handleMobileUnsubscribe ran unconditionally
  after a rebind. Presence is keyed (ptyId, clientId) with no refcount and `closed`
  is exactly the post-rebind state, so a superseded handler deleted the replacement
  subscriber's presence. Gate it on the registration still being current. This also
  gives SubscriptionRegistration.isCurrent its production caller.

- The STA-4510 regression test hand-rolled a second registry copy that diverged from
  the shared double (no try/catch around cleanup, no in-flight join). Import the
  shared double instead, so the test proving the bug uses the same fidelity as the
  rest of the suite.

- cleanupSubscriptionIfOwnedByConnection treats an absent connectionId as authority.
  That is the connection-less local unix-socket path, not an oversight; say so.

* fix(runtime): drop the lease-only presence guard; it disabled a real compensation

Review pass 2 showed the guard added in the previous commit was wrong.

registration.isCurrent() is always false whenever `closed` is true: either our own
cleanup ran, in which case cleanupSubscriptionAndWait already deleted the map entry,
or a rebind replaced it. So the guard did not distinguish the two cases — it made the
compensating handleMobileUnsubscribe unreachable, which is precisely the
resurrect-after-cleanup case that line exists to handle.

The scenario the guard was meant to fix is also not reachable: the lease-only call
passes no viewport, and both !viewport paths in handleMobileSubscribeInternal return
with no await, so the subscribe resolves in microtasks and a socket close cannot win it.

Revert the guard, and drop SubscriptionRegistration.isCurrent with it — it had no
remaining production caller and shipping unused runtime API invites exactly this.

Also from review:
- cleanupSubscriptionIfOwnedByConnection reported false for an id with no registration,
  conflating 'refused, another connection owns it' with 'already gone'. Report true.
- Note on the registry double that it mirrors production and can drift; the runtime
  tests pin real behavior, the doubles only pin routing.

* fix(runtime): make the unsubscribe refusal observable and restore test-double parity

Review pass 3:

- The registry test double omitted production's 'unregistered id is already gone'
  early-out, so it returned refused where production returns gone. The legacy
  terminal.unsubscribe path reaches that branch with a never-registered bare id, so a
  routing test would have locked in the inverse of production.
- terminal.unsubscribe ORed the bare-id and composite results. Registrations always use
  the composite, so the bare id reported 'already gone' and masked a real ownership
  refusal: a stale connection was correctly refused but told unsubscribed: true. The
  composite answer is authoritative when we try it.
- Pin why the lease-only compensating handleMobileUnsubscribe is deliberately unguarded:
  it is safe only because that call passes no viewport and returns with no await.
- Cover the no-registration branch, which had no test.

* fix(runtime): report an unsubscribe refusal without masking a real teardown

Review pass 4 disproved the previous commit's rationale. A clientless legacy-JSON
stream registers under the bare terminal id, not the composite, so either call in
terminal.unsubscribe can be the real teardown. Overwriting reported false after a
destructive success; the earlier OR reported true after a refusal. AND over the calls
that actually ran is the honest aggregate: false needs a genuine refusal.

Tests:
- cover the bare-id path, which the ownership tests never exercised
- pin the microtask invariant the unguarded lease-only compensation depends on. The
  first version of that test was vacuous: it raced two setTimeout(0) timers, and the
  earlier-registered one always won, so it passed with an await injected. It now drains
  microtasks only and goes red under that mutation.

Brennan BensonandQA 64de8dd637 fix(workspaces): delete on the confirmed host, and make both hosts' rows selectable (STA-4343) (#15013)
* fix(workspaces): host-qualified workspace deletion (STA-4343, STA-4448)

Squashed integration of PR #14606 + the codex review-loop output, replayed
onto current main. Granular history preserved on brennanb2025/sta-4343-review-full.

Fixes the regression from #13413: a workspace id is repoId::path with no host
component, so the same repo at the same path on two hosts published one id for
two workspaces, and deletion routed by that id landed on whichever host routing
preferred - usually the ACTIVE one, not the row the user confirmed.

- removeWorktree takes a REQUIRED host-qualified WorktreeRemovalTarget; omitting
  the host is a type error. All destructive callers migrated.
- Projections dedup on (host, id), so two hosts render as two selectable rows
  while the createWorktree/fetchWorktrees race duplicate still collapses.
- Ephemeral VM cleanup is host-scoped. It matched on bare workspaceId, so the
  host-scoped delete path destroyed the SURVIVING host's VM and its unpushed
  filesystem - a leak fix that had become data destruction.
- Selection, keyboard routing, lineage grouping and Space rows carry host
  identity end to end; fixing the executor dedupe alone would have turned
  one-row intent into deleting both hosts.

Files split to stay under max-lines rather than raising any cap.

* refactor: split files that crossed max-lines

The review-loop commits used --no-verify, so the pre-commit hook never
enforced the caps. Extracted cohesive units rather than raising any limit:
renderer teardown, delete-with-toast, pinned-group rows, host-scope helpers,
workspace-kind predicates, filter actions, kanban drag selection, the
renderer removal result type, and the native-chat persistence tests.

* refactor(workspaces): extract cleanup deletion-phase selector

Clears the last max-lines violation and the import-type side effect the
changed-code gate flagged.

* refactor(sidebar): track the delete-dialog extraction modules

* fix(workspaces): preserve host identity across remaining surfaces

* fix(sidebar): re-carry host through the rewritten palette result model

#15170 replaced PaletteSearchResult while this PR was open. Re-applied the
host qualification on top of the new model instead of taking either side:
results carry worktreeHostId again, and the board filter keys its matched
set on host identity rather than the bare id.

Known gap, documented in the board test rather than deleted: searchWorktrees
resolves evidence through a `documents` map keyed by BARE worktree id, so two
same-id host rows collapse before this code sees them. Closing that belongs
with the palette work.

* test(cmd-j): pin the palette collision gap instead of asserting the old model

The palette collision test asserted two host-qualified rows, which #15170's
rewrite made unreachable: item ids are bare again and worktreeMap is id-keyed.

Rewritten to assert what holds — activation always names a host — and to pin
the defect it exposes: two same-id rows render on ONE command value, so React
sees duplicate keys and a click on the first row activates the second row's
host. That reproduces on main, so it is pre-existing, not from this PR. Pinned
rather than deleted so fixing it must update this test.

Brennan Benson 1a04d292b6 fix(agents): lift the pane retirement fence when a live PTY re-attaches (STA-4114) (#14624)
* fix(agents): lift the pane retirement fence when a live PTY re-attaches (STA-4114)

A detach/reattach cycle retires the pane on both sides — the main hook
server's closedAgentStatusPaneKeys and the renderer's
recentlyRetiredAgentStatusPaneKeys — and nothing ever cleared either one.
The pane then rejected every later working/done event for the rest of its
life while Pi kept running normally in the same PTY.

Bind the fence to the fact it asserts: retirement claims the pane is gone,
and binding a live PTY to that exact pane disproves it. Clear both
tombstones at the spawn/attach chokepoint and at the daemon-backed reattach
path, so recovery does not depend on the agent starting another turn — a
pane re-attached mid-turn only has agent_end left to report, and one
re-attached while idle emits nothing at all. Closed-tab tombstones are a
separate, stronger claim and are deliberately left standing.

* test(agent-hooks): re-arm the idle re-attach test against a turn-boundary fix

The idle re-attach assertion posted only before_agent_start, which #14626
turns into a fence-lifting turn boundary. Under that change the test passes
whether or not restorePaneAuthority runs, so it stops pinning this PR's
mechanism. Assert first on agent_end — a non-turn event — so the test proves
the fence was already down when the hook arrived.

Verified: with restorePaneAuthority neutered AND before_agent_start added to
the restart predicate, the old assertion passes and the new one fails.

* fix(agents): lift a retired pane's whole fence, aliases included (STA-4114)

Retirement fences the pane, its resolved owner, and every alias of it, then
deletes those aliases. Restoring only the key handed to us left the rest
standing — and a detached pane's process keeps posting the key it launched
under (server.ts:1614), so the canonical re-attach case stayed suppressed
with the fence apparently lifted. Verified against the real omp binary: the
row came back under the stale launch pane instead of the detached owner.

Record what each retirement fenced and replay it as a unit, rebuilding the
aliases it deleted. Keys and aliases belonging to a closed tab are skipped,
so the stronger claim survives and a live process is never routed back into
a closed tab. The record is indexed by every fenced key and bounded at 1024
like the maps it mirrors; an evicted record degrades to the old behaviour.

Also records why the renderer's restore IPC is deliberately unguarded: that
map is not a mirror of main's (retirePtyAgentLaunchAuthority fences main
directly on command-finished and PTY exit, and nothing pushes it back), and
it is per-window and non-persisted, so gating the send on a local tombstone
reintroduces this bug for exactly those panes.

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.

  imports the barrel
- browser-runtime.ts -> describe-page/live-browser-url-registry.ts (banned
  name; relocating the contract collapsed the host-guest/navigate mutual pair)
- repath browser-pane test paths in config/reliability-gates.jsonc

* refactor: sync addressBarValueRef with useEffect

Move ref synchronization into useEffect hook with proper dependency
tracking to ensure the ref updates are handled through React's
lifecycle. Consolidate related imports from browser-page-types.

* refactor(browser-pane): fix React lifecycle and external store patterns

- Replace local state + effects with useSyncExternalStore for external subscriptions (draw hint, address bar, slot viewport)
- Fix React StrictMode double-invoke issues in pointer handlers and state updates
- Add keyboard navigation to context menu (arrows, Home, End, Escape) with focus management
- Improve error handling for mobile driver reclaim and grab action IPC failures
- Add test coverage for BrowserFind session flags, keyboard behavior, viewport lifecycle
- Remove react-doctor/no-adjust-state-on-prop-change lint disables (root causes now fixed)

* i18n: extract grab and download UI messages

Move hardcoded toast notifications and error messages to translation
system for both grab annotations and file drop handling. Also apply
lazy initialization to address bar value and remove duplicate event
recording.

* fix(browser-pane): stop mutating refs during render

React Doctor fails static analysis when refs are written in render.
Mirror latest values in useLayoutEffect, and read the current page id
from the latest grab callbacks.

* fix(browser-pane): drop unused grab-mode exit dependency

exit already reads the page id from a ref, so listing browserPageId
trips the changed-code exhaustive-deps gate.

* test(e2e): hide the window when Linux minimize is a no-op

Xvfb has no window manager, so BrowserWindow.minimize() never sets
isMinimized() on the frameless Linux CI window. Hide still occludes
the guest compositor so restore coverage can run.

Jinjing 39260d16c7 test: properly clean up in-flight checkpoints before disposal (#15010)
Release stalled operations, wait for pending checkpoint work to
complete, and stop checkpoint timers before disposing the adapter.
This prevents abandoned checkpoint tmp/rename operations from
recreating files under the temp directory before it's deleted.

Jinjing 2aebcfe288 Improve cmd j search keyword match (#15170)
* Implement multi-keyword palette matching with evidence-based ranking

Replaces the single-match-per-field scoring with a comprehensive matcher that:
- Validates token coverage across multiple query keywords
- Normalizes Unicode text consistently across all sections
- Classifies matches by quality for cross-section leadership
- Supports evidence-based matching with hidden supporting fields
- Includes typo matching for letter-only words
- Performance-gated against a synthetic corpus of 800+ candidates

Result structure now carries match ranges per field (not per row), quality class, and document rank so sections can compare relative strength. This enables worktree/open-tab/intent section ordering based on match intent rather than hardcoded defaults.

* Improve cmd-j palette selection after deferred query commits

Instead of clearing selection when the deferred query commits,
intelligently select the next available item using the standard
selection logic. Also remove unnecessary array index from React
key generation to prevent spurious re-renders.

Brennan Benson 32ee3b0536 reland(browser): route every cookie-import write through CDP identities, and never clear what it will not write back (#15030)
* reland(browser): restore CDP-identity cookie-import writes (#14729)

Reverts the revert 3c8410d927 (#14942) to restore the reviewed bf6dc6fcba
tree. The defect that caused that revert is NOT fixed by this commit — it is
fixed in the commits that follow, so the delta a reviewer must scrutinise
stays small instead of hiding inside a 2000-line re-add.

Conflict resolutions, all keep-both:
- browser-cookie-import.ts: two hunks around the zero-import early return.
  #14683's undecryptable warning and decryptedCookies.length === 0 condition
  are kept alongside the reland's old-client gate and partitionSkippedCookies.
  The old-client gate stays above the early return, and so above any mutation.
- en.json: both string sets (#14683's undecryptable copy and partitionSkipped).
- crashpad-capture.test.ts: took HEAD wholesale; unrelated to this ticket.

getStoragePath, and its positive-write assertion moves from cookies.set to the
CDP identity store — adapted, not weakened, and now strictly stronger because
it also asserts cookies.set carries no imported user data. Every decryption
assertion is untouched.

* fix(browser): add registrableFamily, one definition of a cookie family

STA-4300, change 1 of the reland fixes. No behaviour change yet — this only
adds the helper the later commits derive every skip scope from.

Deriving "family" inline in several places is what let the removal scope and
the write set disagree in STA-4090 and STA-4170, so there is exactly one.

The IP check runs on normalizeCookieDomain's OUTPUT, never the raw string.
psl treats an IPv4 literal as a dotted DNS name — psl.parse('127.0.0.1').domain
is '0.1' — and Chromium accepts many spellings of one address. new URL() inside
normalizeCookieDomain canonicalises 127.1 / 2130706433 / 0x7f.1 / 010.0.0.1 and
a trailing dot to a dotted quad first, so isIP() then catches all of them.
Mutation-proved: moving the check ahead of normalisation reddens the five
alternate-spelling cases and nothing else.

Bracketed IPv6 needs its own branch because isIP('[::1]') is 0; without it the
value falls through to psl, which throws, which returns the host — the right
answer for the wrong reason.

Returns null for a bare public suffix: naming `com` as a family would preserve
an entire TLD from removal and silently turn an import into a no-op.

* fix(browser): plan every cookie's fate before any jar mutation

STA-4300, change 2. Adds planImportWrites — pure, no I/O — so the write set and
every removal scope can derive from one value instead of being computed twice.
Not yet wired into the import paths; that is the next commits.

TWO passes, and the second is not optional. Family-atomic skip is a property of
the whole input: with a readable mixed.example row BEFORE an unreadable
sub.mixed.example row, a per-row guard emits the readable one before anything
knows the family will be skipped. Pass 1 classifies and collects the skipped
families; pass 2 re-filters the provisional writes.

Mutation-proved with a faithful one-pass guard (consult skippedFamilies as you
go): the readable-before-unreadable case goes red and the unreadable-before-
readable case still passes. That asymmetry is why both orders are tested and
why only the first is the named detector.

Family closure is at the registrable boundary because that is the boundary the
removal scope actually expands to: importedDomainScopes turns an imported
mixed.example into descendant roots, so a readable apex cookie drags a skipped
subdomain's live session into the removal scope (STA-4300 §2b).

hasUnrepresentableSkip surfaces a skip whose family cannot be named. A family we
cannot name is one we cannot exclude from the removal plan, and clearing a
family we cannot protect is the P0 this ticket exists to stop — so the caller
refuses before mutating rather than proceeding and hoping.

* fix(browser): derive path A's removal scope from the write plan (STA-4300 §2b)

Change 3. importValidatedCookies now plans before it opens the jar, and the
replacement scope and the write set are the SAME array.

bf6dc6fcba filtered replacementDomains per exact cookie
(partition.status !== 'unreadable'). That is not sufficient:
replaceCookiesForImportedDomains expands each imported domain into its
descendant roots, so a readable cookie on mixed.example pulls sub.mixed.example
into the removal scope — and a skipped cookie living there has its session
removed with nothing written back. Same erasure as the P0, different path.

plan.writes is family-closed, and because path A passes the very same array to
replaceCookiesForImportedDomains and to writeImportedCookies, the two sets
cannot drift apart. That is stronger than keeping them in sync: there is only
one set.

Also here, both before any mutation:
- an unrepresentable skip (registrableFamily → null) refuses the import, because
  a family we cannot name is one we cannot exclude from the removal scope;
- the old-client gate now keys off plan.skips rather than re-deriving the
  condition.

Counters: partitionSkippedCookies is a BREAKDOWN of skippedCookies — the
unreadable rows plus their family-suppressed siblings — added in exactly once,
so totalCookies === importedCookies + skippedCookies keeps holding. Counting it
separately is how a summary silently stops adding up.

Full src/main/browser suite: 69 files, 729 tests, green.

* fix(browser): split path B into scan and emit, and never stage a skip (STA-4300)

Change 4 — this is the commit that fixes the shipped P0.

bf6dc6fcba did:
    decryptedCookies.push({ ..., partition })   // write set built HERE
    if (partition.status === 'unreadable') { ... continue }   // guard AFTER

so an unreadable row discovered late could not retract a sibling already
emitted, while removeTransplantableCookies cleared the ENTIRE jar. The mutation
set was the whole jar and the write set a strict subset of it, which is how a
mixed readable/unreadable source emptied a populated jar and repopulated only
part of it.

Now the row loop SCANS only. Nothing is emitted inside it — not decryptedCookies,
not domainSet, not a staging row, not the imported count. Between scan and emit,
planImportWrites closes the skip over whole registrable families, and emit walks
the plan. Each scanned candidate carries its raw source row because
buildChromiumCookieInsertParams needs it; a record holding only the derived
fields compiles and then silently cannot stage.

Also between scan and emit, both before any mutation:
- an unrepresentable skip refuses the import;
- any skipped family calls disableStaging. A staged image is a whole-database
  replacement on the next start, so it cannot express "preserve this family";
  main's existing memoryFailed arm then reports restart-fallback-unavailable.

Test contract change, deliberately stronger: "never stages a partitioned row
whose ancestor bit is unreadable" asserted that an image WAS registered and
merely omitted the row. That image would still have erased the preserved family
on replay. It now asserts no image is registered at all — plus a new paired case
proving a no-skip import still stages, so "disable on skip" cannot be
implemented as "disable always" unnoticed.

Honest note on detection: reverting the emit filter currently reddens only the
staging assertion, because every end-to-end fixture in this module still starts
with an EMPTY jar — where clear-then-write-all and clear-then-write-some are
indistinguishable. That is the blind spot that let this ship. The populated-jar
suite in the next commit is what actually detects the erasure.

Full src/main/browser: 69 files, 730 tests, green.

* fix(browser): never remove a family the import declined to write (STA-4300 I2)

Change 5, and the one that makes preservation observable.

removeTransplantableCookies takes preserveFamilies. removableCookieEntries
filters those families out, which keeps them out of the removal plan AND — since
the CDP snapshot is taken from that same list — out of the restore set, so a
preserved coordinate is never submitted to any mutation at all.

When anything is preserved, the bulk clearData path is not used. clearData
removes everything outside excludeOrigins, and its own comment concedes a
rejection may already have emptied part of the jar; a preserved family is
deliberately absent from the snapshot, so a partial delete followed by a
rejection would destroy it with no identity able to restore it. Handing a
dynamically derived preserve list to that primitive cannot be made safe, so a
skip-bearing clear runs the frozen per-coordinate plan — which already excludes
those families — as its primary path instead. Nothing is preserved on an
ordinary import, so that path keeps today's single clearData call unchanged.

New populated-jar suite. Every end-to-end fixture in this module starts with
cookies.get returning [], and against an empty jar "clear then write all" and
"clear then write some" are indistinguishable — which is why four independent
gates missed the P0. These fixtures start populated.

Mutation-proved, and this is the first detector in the change set that catches
the actual erasure rather than a proxy:
- drop the preserved-family filter          → 6 of 8 red
- use bulk clearData while preserving       → 6 of 8 red, including
  "leaves a preserved family untouched", which is the erasure itself

IPv4-literal and single-label host families are covered explicitly: psl reads
127.0.0.1 as the dotted DNS name '0.1', so a wrong family here would fail to
match the preserve set and erase the live loopback session.

* test(browser): pin STA-4300 end to end in real Electron, both write paths

Ports the pre-implementation reproduction into the PR. Verified RED against
main's product code and GREEN with the fix, on both paths — I re-ran it both
ways rather than assuming.

Two assertions are INVERTED rather than deleted, and both are now stronger. The
repro proved the defect by showing cookies.set was called WITHOUT a partitionKey;
after the reland the import write path does not touch cookies.set for user data
at all, so seeing the imported cookie there is itself the regression. The
fixture's internal guard is inverted the same way.

Non-vacuity, asserted in-run rather than in a report: ok:true with a nonzero
importedCookies, the importer reaching its terminal step, the source really
carrying its partition fields, and a CONTROL cookie written via CDP *with* a
partitionKey and read back with it — so "partitionKey absent" cannot be confused
with "the oracle cannot see partitions". electronVersion proves Electron ran.

Fixture correction worth recording, because the original reproduction was
invalid on this path and I did not catch it on first read: readJsonCookiePartition
reads a NESTED partitionKey object, but the fixture wrote topLevelSite and
hasCrossSiteAncestor at the entry's top level, where the importer never looks.
The file/paste case therefore failed on main for a fixture-shape reason rather
than for the defect — and its own non-vacuity check validated what the fixture
wrote instead of what the parser reads, which is exactly how a check that looks
rigorous proves nothing. Only the native half was ever a real reproduction.

Partition keys use a schemeful SITE, not an origin: Chromium canonicalises
https://app.example.com to https://example.com, measured via CDP.

* fix(browser): fail closed on lossy cookie identity recovery

* fix(browser): preserve unreadable families before decrypt

* fix(browser): reject malformed cookie partition sites

* fix(browser): validate recovered cookie partition sites

* fix(browser): reject empty JSON partition identities

* fix(browser): fail closed and serialize cookie imports

* fix(browser): reject malformed CDP opaque flags

* fix(browser): roll back outcome-unknown cookie writes

* revert(browser): move import serialization out to STA-4601

Reverts only the concurrency-serialization half of f7c27b71ab so #15030 stays
scoped to the STA-4300 reland. That commit mixed two concerns; this removes one
of them and keeps the other.

REMOVED (moves to STA-4601, a separate pre-existing P1):
- acquireCookieMutationLock / withCookieMutationLock and the mutationLocks map;
  clear.ts goes back to withCookieClearLock
- the import-wide lock in path A (mutationOwner on the target, acquire/release
  around replace + writes + rollback)
- the widened lock around path B's clear + memory writes
- browser-cookie-import-concurrency.test.ts

KEPT (genuinely STA-4300 scope, not concurrency):
- partitionKeyOpaque handling in readJsonCookiePartition and the CDP snapshot.
  An opaque partition key cannot be represented faithfully, so it reads as
  unreadable and its family is preserved — exactly the rule this ticket adds.
  194e57a628's refinement of that shape stays too.

The concurrent-import interleaving is real and reachable (nothing serialises
imports per partition, and the clear lock is released before the memory writes),
but it predates this change and is not caused or worsened by it. It gets its own
PR and its own review rather than riding a P0 reland whose history is that every
additional fix introduced a new defect.

src/main/browser: 71 files, 772 tests, green. Electron oracle still passes on
both write paths and still goes red against main's product code.
