Neil ea01cd0ccd fix(windows): reject a node-pty addon that predates the MSYS breakaway denial (#20047)
* docs(windows): record the measured MSYS job-breakaway mechanism

The per-PTY job already denies JOB_OBJECT_LIMIT_BREAKAWAY_OK for Cygwin/MSYS
shells (#19068), but nothing records why, and a conpty.node built before that
commit fails windows-msys-job.win32.test.ts in a way that reads as a source
defect. Measured on a real Windows 11 host: both the plain and the exec-
replacement Git Bash shapes leak, the escape is the MSYS runtime's own
spawn/exec (fork keeps membership), and a single-variable A/B on
usesCygwinRuntime flips the result 0/2 -> 4/4.

Also names the gap the failure hid behind: node-pty-job-ownership.cjs asserts
symbol presence, which cannot distinguish patch revisions.

* fix(windows): reject a node-pty addon that predates the MSYS breakaway denial

The native-runtime gate asserted only that terminateJob, listJobProcessIds and
assignCurrentProcessToJob were exported. All three predate the Cygwin/MSYS
breakaway denial, so an addon built before it passes every gate,
isPtyJobOwnershipAvailable() returns true, and windows-pty-job.win32.test.ts
passes 6/6 -- while every Git Bash child is created outside its pane's job and
survives terminatePtyJob.

Read the resolved .node and require the wide msys-2.0.dll literal that
usesCygwinRuntime holds, the way stagedRelayAddonIsUnpatched() already tells a
patched windows-process-tree addon from a published one. An addon the caller
cannot name is refused rather than skipped: a gate that cannot see its subject
is not a gate.

Verified against real binaries on a Windows 11 host: the shared checkout's
pre-#19068 build errors, a build from current patched source passes, a missing
path errors.

Also closes the cross-host packaging skip. The export half has to load the
addon so it cannot run when the packaging host is not the target, which is how
a Windows release built elsewhere could ship this. The marker is a file read
and needs neither; an unrecognised layout warns rather than fails a release
that was packaging fine.

* fix(windows): check the MSYS breakaway denial on the rebuild path too

The Electron probe carried the marker check, but it lives inside
probeElectronNativeModules, which returns early whenever the Electron package
binary is unusable. Covered by another path is not this path checks -- and the
defect this whole change closes was a gate that looked like it checked.

Reading the binary needs neither a loadable Electron nor an executable target
arch, so assert it after the rebuild, beside the windows-process-tree
assertion that exists for the same reason: this is the addon copied into the
packaged app. Absent warns (a cross-platform rebuild need not leave a win32
addon on this disk); present and unmarked is fatal.

The fixtures now write a real addon file, because the gate reads the binary it
was told about rather than trusting the exports. Verified against the two real
binaries measured on the Windows host: the pre-#19068 build fails this path,
the build from current patched source passes.

* fix(windows): check the marker on every ConPTY path the packaged app can load

The packaged marker check read one hard-coded path, `build/Release/conpty.node`,
and warned when it was absent. `loadNativeModule` tries `build/Release`, then
`build/Debug`, then `prebuilds/win32-<arch>`, swallowing each failure, and
`prunePackagedNodePty` drops the published prebuild only when a same-arch
`build/Release` exists to replace it. So the two packages the check was added for
were the two it could not see:

- cross-host: no host but Windows can build conpty.node, so there is no
  `build/Release` and the prebuild is what ships. The check warned and returned.
- cross-arch: `build/Release` is the packaging host's own arch, patched and
  marked, so the check printed OK -- while the target app cannot load it and
  falls through to the unmarked prebuild underneath.

Measured, not assumed: both published Windows prebuilds in the node-pty tarball
contain neither `msys-2.0.dll` nor `cygwin1.dll` in any encoding. They are the
binary that leaks every MSYS pane child out of its job.

It now sweeps every candidate present for the *target* arch and refuses a package
with no candidate at all, which is a package with no ConPTY backend rather than a
layout to shrug at. It runs for every Windows slice instead of only the branch
the export check skips, so deleting the export check cannot silently take it too.
A stale source build keeps the rebuild advice; the prebuild gets the advice that
actually works, which is to package the slice on a Windows host of that arch.

Also: the marker constant was re-typed in four places and was tied to the C++
literal that produces it by nothing at all, so editing the patch would have left
a gate that fails every correctly rebuilt addon and tells the developer to do the
one thing that cannot help. The fixtures now take the constant from the gate, and
a test asserts the patch still adds `L"msys-2.0.dll"` to conpty.cc.

And the rebuild path treated a missing addon as a warning even on the host that
will run the install, where node-pty would fall through to that same prebuild.
The verdict is now a value, so it is tested without a platform gate.

* fix(windows): resolve the packaged ConPTY the way its loader does

Sweeping every candidate and demanding the marker on all of them was wrong in
the one case it was meant to make safe. `beforeBuild` runs
`rebuild-native-deps.mjs --platform=win32 --arch=<target>`, so a cross-arch slice
normally does get a patched `build/Release` for the target; `prunePackagedNodePty`
keeps the prebuild anyway because its guard is `electronArch === process.arch`
rather than the arch of the binary. That package is correct and its leftover
prebuild is never reached, and the sweep failed it -- telling whoever ran it to
package on a Windows arm64 host, which is both the wrong remedy and one no runner
here can offer.

Presence cannot separate that package from the one whose cross-arch rebuild
quietly emitted the host's architecture, because the only difference is the arch
of `build/Release`. So the gate now resolves the addon the way `loadNativeModule`
does -- first candidate whose PE `IMAGE_FILE_HEADER.Machine` matches the target,
walking root-then-lib for each layout in node-pty's own order -- and checks the
marker on the one that will actually run. A package with no candidate, or none of
the target's architecture, is refused: it has no ConPTY backend either way, and
the second is exactly what a silently host-arch cross-build looks like.

The PE machine reader already existed, privately, in the relay addon builder that
needed the same "a cross-build cannot silently emit host arch" guarantee. It is
now shared rather than copied.

Two seams were unreachable from anything but Windows, so nothing tested them:

- the afterPack hook's win32 block was an inline if/else that only a source-text
  assertion could inspect, and that assertion could not tell the difference
  between the check running and the check being wrapped in `try {} catch {}`. It
  is now `verifyPackagedWindowsNodePty`, and "the marker check runs even where
  the export check cannot" is four spied assertions instead of a string match.
- the rebuild path's verdict read `process` directly, so the branch that fires
  only on the host being rebuilt for was dead on every other host. It now takes
  the host as arguments, and the fs checks, the warning and the failure are all
  exercised from macOS.

Fixtures write a real PE header rather than `MZ fake addon`, since the gate now
reads one. The machine table is pinned to the documented IMAGE_FILE_MACHINE
values, because every fixture builds its header from that table and a table wrong
in both entries would otherwise agree with itself.

* fix(windows): say why the packaged ConPTY fell back, not just that it did

The previous commit resolved the addon by architecture but still had one message
for every way the resolution could land on the published prebuild. Those ways
want opposite remedies, and the one it printed was the remedy the commit before
it had just called wrong:

- no source build in the package at all — the slice has to be built somewhere
  that can build node-pty for the target arch.
- a source build that is there but is the packaging host's architecture, because
  the cross-arch rebuild did not honour `--arch` — re-running that rebuild is the
  fix, and "package on a Windows arm64 host" is neither necessary nor possible.

The second is the common one, since node-pty publishes a prebuild for both
Windows arches and prune keeps the target's on every cross-arch package. So the
old text fired mostly on the case it described least. It now reports which source
builds were skipped and the machine field each carried, and names the rebuild
command.

"Nothing the target can load" had the same problem in reverse: a zero-length or
truncated `conpty.node` got a cross-architecture diagnosis. Every candidate is
now named with what was actually read, including "not a PE image".

The rebuild path asserts the architecture too. A rebuild that ignored `--arch`
was otherwise only visible at packaging, two steps from the command that fixes
it. Arches with no known machine value are left unjudged rather than guessed at.

Two things the extraction broke or nearly broke, both found by mutation:

- the shared PE reader answers `null` where the relay builder's private copy
  returned a number, which would have turned its "node-gyp ignored --arch" error
  into a `TypeError`. Both callers now go through `describePeMachine`.
- the rebuild fixtures stage a script's co-located modules by walking its
  imports, and the walker only understood `from '...'` — so the gate's new
  `require('./windows-pe-machine.cjs')` was left behind and every subprocess test
  failed with a resolution error, which is the exact failure its own comment
  warns about. It now follows `require` and bare side-effect `import` as well,
  and has tests; the fixture stages the gate by walking it rather than by naming
  one file.

Fixtures write real PE headers through one shared builder instead of three
hand-rolled ones.

* fix(windows): run the node-pty addon gates on the Windows job that can

`rebuild-native-deps-node-pty.test.mjs` carries four `skipIf(platform !== 'win32')`
tests. The full suite runs on ubuntu, and the Windows PR job runs an explicit
file list that never named this file -- so those tests were skipped on Linux and
never reached anywhere else. Three of them predate this branch. The Windows job
is added the four node-pty addon suites plus the module-walker one; the comment
above that list already says why it is the right place, which is that the addon
assertions only hold once natives have been rebuilt. Running the path-joining
suites there also covers the separator this gate's candidate list is built from.

The rest is round-three review:

- the rebuild-time arch assertion told a reader "node-gyp did not honour --arch"
  about a file that was not a PE image at all, which is a truncated or
  quarantined artifact and a different command to run. The two now read
  differently, and neither claims the other's cause. Same fix the packaged gate
  had one commit ago, in the place that had not had it yet.
- the missing-addon error said node-pty "would load" a prebuild without checking
  it is there. It says "fall through to" now, which is true either way.
- `isLoadableByArch` had no caller left once the packaged gate started needing
  the raw machine field for its message. Removed rather than kept warm.
- each candidate's header is read once instead of up to three times.
- the module walker's comment claimed every shape that reaches a co-located
  module; it does not follow `projectRequire`/`requireLocal`, and it must not --
  those specifiers resolve against the project root, so following one stages the
  wrong path and the copy fails. Proven by trying: widening the pattern to
  require-shaped names broke nine tests on
  `projectRequire('./config/scripts/...')`. The comment now says what it follows
  and why it stops there.
- a new test resolved a file URL with `.pathname`, which keeps the drive-letter
  slash on Windows -- the very job this commit adds it to.

* docs(windows): put the superseded export-only gate in the past tense

It describes what used to pass a broken addon, so present tense reads as a
description of the gate the same document then explains replacing it.

* fix(windows): repair what running the node-pty suites on Windows exposed

Putting these files on the Windows job turned four assertions red on the first
run. Three of them were in tests that carried `skipIf(platform !== 'win32')` and
had therefore never executed anywhere, on any branch.

- `writeFakeElectronRebuild` emitted the `windows-process-tree` addon a real
  rebuild leaves but never node-pty's, so every Windows test of the rebuild path
  ran against a tree no real rebuild can produce: node-pty "rebuilt" with nothing
  in `build/Release`. The new same-host check reads that state correctly and said
  so. The fake rebuild now writes `build/Release/conpty.node` when it was asked
  to rebuild node-pty for win32, with the marker and the target machine.
- `mkTempProject` never staged `windows-process-tree-creation-time.cjs`. The
  rebuild script reaches it through `projectRequire`, which resolves against the
  project root, so the module walker cannot follow it and must not try. Staged by
  name, with a comment saying which of the two it is. Without it the
  windows-process-tree probe failed to load its own checker and the module joined
  `modulesToRebuild`, which is the second and third red assertion.
- the two `nodePtyAddonPath` cases compared against a literal POSIX string.
  `resolve` returns a drive letter and backslashes on Windows, so they could only
  ever pass off it. Built from segments now, which still pins the `..` traversal
  that is the point of the test.

Verified on macOS: ensure-native-runtime-job-ownership,
verify-packaged-node-pty-job-ownership, windows-pe-machine,
script-module-dependencies, rebuild-native-deps-node-pty, rebuild-native-deps,
rebuild-native-deps-windows-process-tree, ensure-native-runtime -- 109 passed, 6
skipped. The 6 are the Windows-gated rebuild tests, which is the job this change
is aimed at; Windows CI is the arbiter.

* fix(windows): give the packaged fallback a third verdict, for a file that is no image

The packaged gate had two remedies for landing on the published prebuild and
picked between them on `!prebuilt`, which puts a truncated, empty or quarantined
`build/Release/conpty.node` in the cross-arch bucket: "the source build beside it
is the wrong architecture ... re-run with --arch". It is not the wrong
architecture, it is not an architecture, and `--arch` is not the command. The
rebuild-path gate was split for exactly this a commit ago; this is the same split
in the place that had not had it.

Also from review of the settled state:

- the stale-source-build branch ended in a call that happened to throw, so a
  reader could not see it was terminal and the file was read twice to get there.
  The verdict is now an Error the caller throws, built once from the read it
  already did, and shared with `assertCygwinBreakawayDenied` rather than copied.
- four injection seams had no consumer in production or in tests
  (`deniesBreakaway`, `peMachine`, and `exists`/`peMachine` on the rebuild
  verdict). An unused seam is a way for the tested path and the real one to drift
  apart; the tests drive both with real files. Removed.
- the loader table existed in a docblock and in the reference doc, already
  disagreeing about row four. The docblock cites the doc now.
- `peImage` stamped machine `0x0000` for an arch it had no value for, because
  `writeUInt16LE(undefined)` coerces to zero. A fixture that quietly invents the
  field the gates read is the same species of silent lie the gates exist to
  catch; it throws, and a test holds it to that.
- a test named for refusing an unreadable candidate asserted only that something
  threw. Renamed to what it proves.

* fix(windows): make the rebuild fixtures represent a tree that can exist

Second round of what running these suites on Windows exposed. The module the
walker could not stage is now staged, so the probe reached its own checker and
the real reasons surfaced:

- `writeFakeWindowsProcessTree` exported `{}`. The creation-time gate reads
  `supportedProcessDataFlags` off the addon and calls its absence "the tarball
  prebuilt, not a build of the patched source" — correctly. The fixture predates
  that gate and, being Windows-only, never met it. The healthy fake now reports
  the flag, taken from the gate's own constant. Two tests were failing on this,
  the second only because the module then joined `modulesToRebuild`.
- `rebuilds a loadable ConPTY native that lacks Orca job ownership` asked for a
  node-pty rebuild in a tree where node-pty had none of the payload its package
  ships. It gets `writeFakeNodePtyConptyPayload` like its two siblings.

I also tried making the fake rebuild emit `build/Release/conpty.node` the way a
real one does, and backed it out: `restoreNodePtyWindowsConptyRuntime` keys off
that file and then reads `third_party/conpty`, so emitting it in a tree without
the package payload turns one honest gap into an ENOENT two steps away. The
payload fixture is where "node-pty has its addon" belongs.

macOS: ensure-native-runtime-job-ownership, verify-packaged-node-pty-job-ownership,
windows-pe-machine, script-module-dependencies, rebuild-native-deps-node-pty,
rebuild-native-deps, rebuild-native-deps-windows-process-tree,
ensure-native-runtime — 112 passed, 6 skipped. The 6 are the Windows-gated
rebuild tests; Windows CI is the arbiter and is why they are on that job now.

* fix(windows): register the node-pty addon suites in the scope list too

Putting the five suites in the Windows lane's vitest argv gets them run once the
job starts; `WINDOWS_PACKAGE_TESTS` in `pr-code-change-scope.mjs` is what decides
whether the job starts at all. Only the argv was updated, so a PR touching just
`rebuild-native-deps-node-pty.test.mjs` would not have started the Windows job,
and its four Windows-only cases — including the same-host-absent one added here —
would have run on no machine for that PR. Exactly the shape of gap this branch is
about. Both lists now name all five, and `windows-pe-machine`,
`windows-pe-image-fixture` and `script-module-dependencies` join
`NATIVE_RUNTIME_PREFIXES` so a change to the modules themselves starts it too.

`win32-test-lane-registration.test.mjs` exists to catch precisely this and did
not, because its matcher only recognises suite-level gates (`describe.runIf` /
`describe.skipIf`) and a `.win32.` filename. These tests gate per `it`. Widening
it is not this branch's change to make: about thirty files across the repo carry
per-`it` Windows gates and are unregistered, so the ratchet would move far beyond
node-pty. Flagged rather than done.

Message repairs from the same review:

- the non-PE arm of the rebuild-time arch error read "... is not a PE image, so
  nothing can load it, so node-pty would fall back ...". The shared consequence
  clause already opens with ", so".
- the no-source-build packaging error ended "Package this Windows slice on such a
  host", which is wrong advice for the case where the host IS such a host and the
  rebuild simply left nothing — reachable when the artifact is removed before
  prune runs. It now names both readings and points at the beforeBuild output.
- the relay-addon builder blamed `--arch` for a build output that is not a PE at
  all, the same guess the node-pty gate was taught to stop making.
- the patch-drift assertion was a bare `toBe(true)`, so a real drift read as
  "expected false to be true". It now names the two things that can have drifted
  and what happens until they agree.

Neil 13ba649c22 fix(terminal): let a runtime-created Windows terminal BE the requested shell (#20825)
* fix(terminal): let a runtime-created Windows terminal BE the requested shell

`orca terminal create --environment <windows-host> --command 'cmd.exe'` never
created a cmd terminal. `--command` is text the provider TYPES into whatever
shell it spawned, so the PTY stayed the host's default shell with cmd running
inside it. Captured on `awin`, whose default is Git Bash:

    $ orca terminal create --environment awin --command 'cmd.exe' --json
    $ orca terminal send --environment awin --terminal term_10656cf7... \
        --text exit --enter
    $ orca terminal read --environment awin --terminal term_10656cf7... --screen
      neil@awin MINGW64 ~/orca/orca ((30f820708f...))
      $ cmd.exe
      Microsoft Windows [Version 10.0.26200.9445]
      C:\Users\neil\orca\orca>exit
      neil@awin MINGW64 ~/orca/orca ((30f820708f...))
      $

The handle is alive the whole time and `terminal list` shows one healthy
terminal, because the PTY never changed — so the only symptom is that the
caller's terminal is now a shell it never asked for, and every later `send` is
quoted for the wrong one. On `win-lowspec` (default pwsh) the same create lands
cmd inside PowerShell.

Root cause
----------
There are two spawn preflights and they are twins:

- `src/main/ipc/pty/ipc/spawn-preflight.ts` — renderer/IPC spawns, i.e. a
  terminal tab opened in the app.
- `src/main/ipc/pty/runtime/spawn-preflight.ts` — runtime spawns: the CLI's
  `terminal.create`, headless `orca serve`, and every paired remote
  environment.

Only the IPC twin read the caller's requested shell. The runtime twin passed a
literal `requestedShellOverride: undefined`, so a runtime-created terminal on
Windows could only ever be the host default. Everything downstream of that
point — `spawn-options`, the daemon, `resolvePtyShellOverride` in the relay,
`local-pty-launch-plan` — already honoured `shellOverride`; nothing upstream
could supply one.

Change
------
- Thread `shellOverride` through the runtime lane: `RuntimePtySpawnArgs` ->
  runtime `spawn-preflight` -> `RuntimePtyController.spawn` ->
  `TerminalCreateOptions` -> the `terminal.create` RPC's new `shell` param ->
  `orca terminal create --shell`.
- Thread it through the renderer-backed lane too (`createDesktopTerminal` ->
  `terminal:requestTabCreate` -> `store.createTab`), so `--shell --focus` is not
  silently dropped on a local Windows app.
- An agent launch quotes its startup command for the shell it will actually run
  in, so a requested shell now owns the startup-shell family instead of the
  global `terminalWindowsShell` setting.
- Lift the relay's `ALLOWED_WINDOWS_SHELL_OVERRIDES` into
  `isSupportedWindowsShellOverride` in `src/shared/windows-terminal-shell.ts`
  (membership unchanged) so the CLI, the zod param schema, and the relay refuse
  the same names. `--shell` therefore cannot carry a path or a command line into
  `pty.spawn`; only allowlisted bare shell names pass.
- Gate on `TERMINAL_CREATE_SHELL_SELECTION_RUNTIME_CAPABILITY`. An older host
  strips the unknown `shell` param and answers with a healthy terminal running
  its default shell — a reply indistinguishable from success — so the CLI
  refuses before creating anything rather than creating the wrong shell quietly.

`--shell` stays Windows-only; macOS and Linux hosts spawn the login shell and
the relay drops the value off win32 rather than honouring it half-way. A WSL
project runtime still outranks it, unchanged.

Tests
-----
- `pty-spawn-shell-override-parity.test.ts` pins both preflights against the
  exact drift that caused this (verified failing with the fix reverted).
- `createTerminal` passes `shellOverride` to `ptyController.spawn` with no
  startup command.
- CLI: sends `shell`, refuses a shell the host cannot spawn, and refuses a host
  without the capability — in both refusals without making the round trip.
- Allowlist and `terminal.create` schema accept/refuse cases, including paths
  and appended arguments.

* fix(terminal): refuse a requested shell the execution host cannot apply

The first commit made `--shell` reach the spawn, but only a LOCAL win32
execution host applies it: `spawn-options` gates the override on
`process.platform === 'win32' && !args.connectionId`. So `--shell cmd.exe`
against an SSH-routed worktree, or against a macOS/Linux host, still returned a
healthy terminal running that host's default shell — the same
indistinguishable-from-success reply the capability gate exists to prevent, one
layer down.

Refuse instead, before anything spawns. The check sits at the top of
`resolveAgentTerminalCreateOptions`, which every create lane funnels through, so
neither lane has to remember it; the desktop lane additionally refuses a
worktree-less create, which has no execution host to resolve a shell on.

An SSH host's platform and installed shells are not visible to this runtime, and
a POSIX host has no Windows shell to pick. Neither can honour the request, and
saying so is the whole point of the flag.

Docs and the CLI spec now say "refused", not "ignored".

* fix(terminal): refuse a shell that contradicts the project execution runtime

`resolveLocalWindowsTerminalRuntimeOptions` does not merely rank the project's
execution runtime above a per-terminal pick -- it REWRITES the pick, in both
directions, and says nothing:

- a WSL project forces `wsl.exe`, discarding `--shell cmd.exe`;
- a Windows-host project discards a WSL name and falls back to `COMSPEC`
  (`getHostShellForProjectRuntime`), so `--shell wsl.exe` spawns cmd. That is
  the common case, not an edge: `resolveProjectExecutionRuntime` resolves
  `windows-host` for every project that is not WSL, while a repo belonging to no
  project honours `wsl.exe` -- so the same flag behaved differently depending on
  whether the repo was in a project.

Either rewrite returns a healthy terminal running a shell the caller did not ask
for, which is the failure `--shell` exists to remove.

It also split an agent launch's quoting from the shell that receives it. The
previous commit made the startup-shell family follow the REQUESTED shell, so
`--shell wsl.exe --command codex` on a Windows-host project typed POSIX-quoted
launch args into cmd. Refusing the contradiction removes that case rather than
papering over it.

Refuse instead, alongside the SSH and non-Windows refusals, from the same
`resolveAgentTerminalCreateOptions` seam every create lane funnels through.

Also from review:
- the allowlist test looped the list against itself; spell the members out.
- the runtime spec case claimed to prove the pty's shell when it asserts the
  controller received the field; name it for what it checks.

Reported by an adversarial review of the branch.

* fix(terminal): canonicalize --shell and refuse a WSL-path rewrite

Review of the --shell create path turned up two ways the terminal could
still end up being a shell the caller never asked for -- the exact failure
--shell exists to remove.

Bare and mixed-case spellings passed the allowlist but reached consumers
that exact-match the canonical name: resolveWindowsShellStartupFamily
classified `cmd` as the PowerShell family, resolveWindowsShellLaunchArgs
fell through to empty shellArgs (no `chcp 65001`, no OSC 133 bootstrap that
Windows foreground status depends on), and resolveWindowsGitBashShellPath
compares case-sensitively so `Git-Bash` spawned a literal `Git-Bash`.
The allowlist is now one canonical-name map and terminal.create canonicalizes
on parse, so the spawn path only ever sees `.exe` spellings. `pwsh` and
`powershell` stay distinct binaries.

A `\\wsl$\<distro>\...` cwd made the providers force wsl.exe regardless of
the request, and terminalShellOverrideRefusal only inspected the project
runtime -- undefined for a folder workspace with no project. Refuse on the
resolved cwd and the workspace path, judging what the PTY actually gets.

Also: the capability gate reported an unreachable host as too old rather
than unavailable; the SSH CLI shim dropped capabilities from status, so
--shell there blamed the host version instead of naming SSH; and --shell
had no help entry, rendering bare in `orca terminal create --help`. Adding
that entry crossed help.ts's max-lines cap, so the flag table moved to
flag-help-text.ts rather than suppressing the rule.

Adds a behavioural test for the runtime preflight (the one-line fix was
pinned only by a source-text scan), plus coverage for the startup-command
quoting family, the no-workspace refusal, and the WSL-path refusal.

* fix(build): keep tests out of the RPC params catalog bundle

The catalog walk under methods/ already skips *.test.ts, but the contract
directory glob took every .ts. terminal-create-shell-param.test.ts is the
first test to live there, so the bundle pulled vitest into a CJS build and
the generator threw on require(). Same exclusion, same reason.

Neil b61a2347b9 feat(design-system): gate renderer UI with @shadcn/lint (#20731)
* feat(design-system): gate renderer UI with @shadcn/lint

Wires shadcn-ui/lint's Oxlint plugin into the two places this repo already
ratchets: the changed-lines PR gate for rules the renderer can't satisfy
today, and `pnpm lint` for the one that is already at zero.

- config/oxlint-design-system.json: no-restyle (layout allowed),
  no-raw-colors, require-static-classes -- scoped to src/renderer/**/*.tsx,
  run over added lines only. Measured at 10 findings across the last 60
  commits (771 changed files), so it holds the line without a migration.
- config/oxlint-dead-classes.json: no-unknown-classes repo-wide, with the
  renderer's plain-CSS hook namespaces allow-listed. Now at zero.
- no-inline-styles and no-arbitrary-values stay off; STYLEGUIDE says why.

Fixes the three live bugs the linter found:

- `--editor-surface` never reached `@theme inline`, so `bg-editor-surface`
  generated no CSS -- 12 editor/artifact/notebook panes fell through to the
  page background instead of #1e1e1e in dark mode.

Neil e86cba888b build: reduce native dependency installs to the host platform (#20420)
* Reduce native dependency installs to the host platform

* Remove install policy documentation

* Guard cross-arch packaging and scope release installs to the runner

electron-builder only logs a warning for a missing extraResources source,
so a host-only install silently shipped a foreign-arch slice without its
natives — `pnpm build:mac` on Apple Silicon produced an x64 DMG with no
sherpa-onnx-darwin-x64 and no @parcel/watcher-darwin-x64. The previous
beforePack hook covered only win32.

- Add assertPackagedNativeVariantsInstalled, an arch-aware check over the
  target's sherpa-onnx, @parcel/watcher, and (on Windows) node-gyp addons.
  beforePack now runs it for every platform, with remedies split: another
  architecture comes from install:release, the os:win32 addons need a
  Windows host.
- Drop --os from the release installs. Every packaging job already runs on
  a runner whose OS matches its target, so only the macOS lanes need extra
  breadth, and only on CPU for their x64+arm64 config. Windows and Linux
  packaging return to a plain host-only install.
- Add --frozen-lockfile to install:release so a bare run cannot rewrite
  the lockfile.
- Restore the install policy reference doc and the CONTRIBUTING note, plus
  the rationale comments dropped from the runtime contract test.
- Gate the packaging-closure assertions on whether the Windows addons are
  installed rather than on the host OS, so a cross-arch install exercises
  them off Windows too.
- Make the workflow contract test read `run:` steps as well as retry-action
  commands, and enforce host-only scoping on the non-macOS packaging lanes.
- Remove the unreferenced install measurement script; its numbers live in
  the policy doc.

* Track the install policy doc and index it from AGENTS.md

docs/** is ignored behind a per-file allow-list, so the new reference doc
was only committed via git add -f and future edits would be skipped. Add
it to the allow-list and give it an AGENTS.md entry like every other
tracked reference doc, so the host-only install rule is discoverable
before someone packages a second architecture.

* Route Windows-lane removals through the retrying helper

Adding these four specs to the PR Windows lane pulled them into the
windows-lane-tree-removal-boundary ratchet, which failed on 20 raw
recursive removals. On Windows a bare rmSync races a handle the OS has
not released, throwing EPERM after the assertions already passed and
reporting a green test as a lane failure.

* Adapt the packaging guard to the vendored Windows registry addon

main vendored windows-native-registry as the workspace package
@orca/windows-registry (#20438). A workspace link resolves on every
host, so including it in the installed-Windows-addons checks proved
nothing. @vscode/windows-process-tree is the only os: win32 npm addon
left, so it alone decides whether the win32 resource plan resolves.

Neil 6bb2b0c6d7 test(runtime): capture real Antigravity transcripts — the detector is inverted on live output (#19983)
* test(runtime): capture real agent PTY transcripts before rewriting Antigravity readiness

Antigravity readiness has been written five times against a five-line screen
typed from memory. There is no Antigravity transcript in this repository, so
every attempt was a guess tested against another guess. This adds the recorder,
the protocol and the fixture-driven suite so the sixth attempt can be written
against evidence, and changes no detector logic.

- config/scripts/capture-agent-pty-transcript.mjs records a live agent session
  through a real PTY, escapes and wrapping intact. Ctrl-] is consumed by the
  recorder and never forwarded, which is the only way to end a capture while a
  dialog still owns the screen.
- config/scripts/pty-transcript-secret-scan.mjs finds account identifiers and
  credentials, redacts them with same-length placeholders so wrapping survives,
  and recognises its own placeholders so a scrubbed file verifies clean.
- src/main/runtime/antigravity-readiness-transcripts.test.ts asserts a verdict
  per transcript and skips by name until the transcripts land, with a
  doc-coverage ratchet and a guard that a fixture contains escape bytes.

The escape-byte guard exists because the three cursor-agent fixtures carry a
comment claiming they were captured verbatim through Orca, yet contain zero ESC
bytes and zero carriage returns. That comment is corrected here to say what
those files are; the fixtures and the rules built on them are untouched.

* test(runtime): capture real Antigravity transcripts, and pin what they prove

`agy` 1.1.25 turned out to be installed, so the transcripts this scaffold was
built for now exist. Six are recorded from live sessions and committed; the
rest are named as skipped, because reaching them would mean signing the
operator out or deleting their config.

The captures invert the story. On real output the shipped detector refuses a
genuinely ready screen and accepts a live `/model` picker:

- Antigravity paints a block-glyph logo down the left, so the model row never
  starts a line. `startsWith('gemini', trimmedStart)` cannot match a real ready
  screen, on any account or model. Stripping the logo flips the same screen to
  ready, which means a decorative glyph decides readiness today.
- The `/model` picker prints `Gemini 3.x Flash` one per line, at line start, and
  a bare `>` composer sits earlier in the tail. Both halves of the rule are
  satisfied while a dialog owns the screen.
- For an API-key user the identity row reads `Gemini API key` — no `@`, no
  domain — and `AGY_CLI_HIDE_ACCOUNT_INFO=1` removes the row entirely. The
  account-row requirement of attempts 4 and 5 can never pass for those users.
- The banner is printed once and never reprinted after a dialog is dismissed, so
  `headerIndex` cannot be the ordering anchor.

Four suite cases are pinned as KNOWN DEFECT: they assert what the detector does
so CI stays honest instead of permanently red, and flip to failing the moment
someone fixes it. No detector logic changed.

The recorder gains `--send "<ms>:<text>"` because a dialog capture has to be
driven and an unattended run has no TTY, and the scrub scanner gains a UUID rule
because agy prints a resumable conversation id on exit.

* test(runtime): capture agy mid-turn, and make the scan file reviewable

Answers the busy-frame question a P1 review raised against attempt six, with
two new captures from a live turn.

At the frame level the review is right: a busy frame parks the caret with the
same bytes as an idle one, `CR ESC[2A ESC[2C`, and the only differing row —
`esc to cancel` versus `? for shortcuts` — is erased by that park.

At the retained-tail level it does not reproduce. Each spinner tick is its own
repaint with its own `CR ESC[2A`, two rows higher than the frame's, which
splices the composer away: a live turn's tail ends on `⣟  Generating...`, with
no bare caret to match. A constructed input that keeps the park and edits only
the status text is not faithful, because a live turn has a spinner row
repainting below the composer.

The residual is the gap between a frame park and the next tick, where the tail
does end on the bare caret. Quiescence-gated paths are safe there because ticks
keep arriving; text-only paths are not, and for those the capture supports one
clause: a braille glyph on the last visible line means working. That predicate
already exists here for cursor-agent and should be reused, scoped to the last
line — a first-run transcript prints `⠾ Signing in...` during startup.

Also in this commit, from the same review:

- pty-transcript-secret-scan.mjs held raw 0x00-0x1f bytes in a character class,
  so the one file gating real PTY data into history was binary to git and
  unreviewable in a diff. It now tests codepoints, which the formatter cannot
  fold back into control bytes.
- Pin `src/main/runtime/__fixtures__/*.txt` as -text. A Windows checkout would
  otherwise normalise line endings and rewrite the CR bytes that make these
  files evidence.

The recorder now stops appending at the stop moment rather than through
shutdown: an agent repaints an idle frame on its way out, which was overwriting
the mid-turn state the capture existed to record.

* test(tooling): allowlist the transcript scan test in the batch-shim ratchet

pty-transcript-secret-scan.test.mjs asserts that the capture recorder routes
an 'agy.cmd' shim through cmd.exe, so the shim literal it names is the
assertion, not a spawn. Fits the existing assert-on-shim-files category.

Brennan BensonandMerge Sim ebb1acfa37 refactor(agent-status): publish structured sessions into the hook server store (#19683)
* refactor(agent-status): publish structured sessions into the hook server store

Structured (native chat) sessions have no PTY and no hook script, so their
status never reached the hook server's store; #19217 gave `worktree ps` its
own adapter over the structured feed instead. The feed now writes every
projection into that store through a status sink the runtime wires, drops
the row when the host closes the session, and `worktree ps` reads the one
snapshot like every other agent.

Rows carry a `structuredHost` marker and the journal clock; they are never
persisted to last-status.json, and the main process does not forward them
to the renderer yet, whose feed bridge still owns them until it is retired.

Design and the two follow-ups: docs/reference/agent-status-store.md.

* chore: drop stray @pnpm/exe lockfile entry

An unrelated local pnpm run added @pnpm/exe as a packageManagerDependency
with no package.json change, so CI's --frozen-lockfile install failed
before any job ran.

* docs(agent-status): describe the step that actually landed

The design record claimed PR 1 deletes RuntimeAgentRowStore, drops the
retained-versus-hook reconciliation, stamps terminalHandle on OSC rows, and
tags rows with a source field of 'structured-host'. None of that is true of
the shipped code: the retained store and its reconciliation are still in
place, and the row field is structuredHost: 'held' | 'owned'.

AGENTS.md points every future contributor here before they touch agent
status, so split the roadmap into the 1a that landed and the 1b that has not,
and name the fields the code actually writes.

* fix(agent-status): pair session removal with the status-row forget

A session dropped from the host's map without an explicit forget left its row
in the store forever: `structuredHostOwned` bypasses the staleness check, so a
failed re-attach (the Claude rewind path reaches one) stranded a permanently
working agent in `worktree ps` and on mobile with no UI able to clear it.
Deletion and forget are now one operation both callers route through.

* fix(agent-status): give orcad the store worktree ps reads from

`orcad` constructed its runtime with neither `getAgentStatusSnapshot` nor
`structuredAgentStatusSink`, so once `worktree ps` sourced rows only from that
snapshot the headless host published nowhere and listed nothing. The hook
server's store is a module singleton whose import tree never reaches Electron,
and its file paths come from `start()`, which orcad never calls.

* fix(agent-status): drop a structured row without a renderer clear

`dropStructuredStatus` went through `clearPaneState`, which fans a pane clear
out to the renderer for a pane key the renderer's own feed bridge still writes
- so 'exactly one writer per pane key' held for writes and not for deletes.
`dropStatusEntry` routes through the status-drop tap instead, and skips the
resume-identity remnant: a structured session has no pane to resume into, and
every null-status publish would otherwise re-mint one.

* test(agent-status): pin both half-migration structured-row filters

Neither the `agentStatus:getSnapshot` filter nor the main-window listener's had
a single assertion, so deleting either — the first step of PR 2 — was green
everywhere. Also covers the perf skip and the drop's lack of a renderer clear.

* docs(agent-status): correct three statements this PR made false

The sink JSDoc claimed only tests construct a host without one; `orcad` did.
The doc argued a structured row needs no tab mirror 'because headless serve has
no renderer', reasoning about exactly the topology the wiring had not reached.
The deleted runtime adapter's warning that the pane key must be the DERIVED one
- never a bearer handle or minted worker key - was lost with it.

* test(agent-status): declare orcad in the hook-row producer census

Wiring the hook store into the orcad runtime added a production site that
hands hook rows to a consumer, which the census ratchet pins deliberately.

OrcaWinandOrca Worker c252d855ac fix(windows): resolve npm/pnpm .cmd shims past cmd.exe (#17869)
* fix(windows): resolve npm/pnpm .cmd shims past cmd.exe

A `.cmd` target forces every spawn through `cmd.exe /c` with each argument
caret-escaped, and Microsoft Defender for Endpoint scores a long `cmd.exe /c`
line carrying caret-escaped natural language as obfuscation. `codex.cmd` is
named in the spawn cluster of the MDE incident this addresses.

npm's `cmd-shim` and pnpm's `@zkochan/cmd-shim` generate files whose whole body
is "find node, run this script". Read one, and the spawn can go straight to
`node.exe <script> <args>` — no cmd.exe, no caret escaping. Anything the parser
does not recognise exactly, or whose target cannot be confirmed on disk, keeps
the existing cmd.exe path.

Incidentally fixes a real bug: cmd ends its command at a raw CR/LF whatever the
quote state, so a multi-line agent prompt through a `.cmd` shim had to be
rejected. Resolved shims have no such limit.

* fix(windows): refuse drive-relative shim paths and run the win32 tests in CI

Two blocking findings from review.

A drive-relative path defeated the absolute-path guard:
`win32.isAbsolute('D:evil.js')` is false, but `win32.resolve` reads the drive
letter and lands on `D:\evil.js`, outside the shim directory. cmd would have
built `C:\shim\D:evil.js` and failed; we would have executed the wrong file.
Adding `:` to the unsafe-character set closes it, and the alternate-data-stream
spelling `a.js:zone` with it. It costs no coverage: 84 of the 91 real shims on
this box still resolve, the same seven fall back.

Neither `windows-cmd-shim-resolution.test.ts` nor its `.win32` sibling was in
the Windows package job's file list, so the whole filesystem/resolution half and
the real-spawn equivalence suite ran nowhere. Both are now in
`WINDOWS_PACKAGE_TESTS` and in the pr.yml step.

Also from review: clear `windowsVerbatimArguments` explicitly on the resolved
branch rather than inheriting it, since there is no caller-built command line
there; document the kill switch and the PTY/hook-wrapper scope limits in
docs/reference; and cover drive-relative, BOM, line-ending, casing and `%*`
tampering in the platform-independent half of the tests.

* docs(windows): justify the shim-path colon guard from the filesystem rule

The guard was argued empirically ("none of the 91 shims on this box has one"),
which invites a future reader to relax it for a shim we have not seen. Windows
reserves `:` within a path segment, so a relative path cannot carry one at all:
the only spellings that can are drive-qualified, an alternate data stream, or a
`\?\` device path, and the last is already refused as absolute. That makes a
false refusal impossible rather than unobserved.

* refactor(child-process): move resolveSpawn into its own module

The merge with main pushed run-process.ts one line past the 300-line cap:
both sides grew it. The spawn-argv decision is already a pure, separately
tested unit, so it moves out rather than the cap moving up. run-process.ts
re-exports it, so no caller changes.

* perf(child-process): cache the shim interpreter lookup

The parse cache spared the shim read but not the PATH walk, so a second
resolution of the same .cmd did 0 reads and one statSync per PATH entry --
30 on a 30-entry PATH, synchronous on resolveSpawn, where one dead network
mount blocks the calling thread on every spawn.

Keyed by shim directory AND PATH, since the shim's own rule is
%~dp0\node.exe first then PATH, and a PATH edit between spawns must miss.
Corrects the stat comment, which accounted only for the shim itself.

* fix(child-process): revalidate a cached shim interpreter before using it

The node cache was held for process life and never rechecked, so a cached
node.exe that was later uninstalled -- or dropped from PATH by a version
manager -- was still handed to resolveSpawn, failing the spawn with ENOENT.
An uncached process in the same state returns null and falls back to
cmd.exe successfully, so the cache was strictly worse than no cache.

One statSync on a non-null hit, not one per PATH entry, so the walk this
cache exists to skip is still skipped. The stale-null direction stays
uncorrected on purpose: it only keeps the working cmd.exe fallback. Both
directions are now stated in the comment, along with the known miss for
callers that vary PATH per spawn.

* fix(child-process): honour PATHEXT when resolving the shim interpreter

The doc claimed a node.com/.bat/.cmd on PATH returned null and fell back to
cmd.exe. The scan actually skipped those entries and kept looking for a
node.exe, so PATH=C:\A;C:\B with C:\A\node.com and C:\B\node.exe resolved to
B's node.exe while the shim runs A's node.com -- a different binary, chosen
silently, on the one axis this module must not get wrong.

The scan now follows cmd's rule: first PATH directory holding any PATHEXT
spelling wins, PATHEXT order decides within it, and only an .exe winner is
returned. Anything else gives up and keeps the cmd.exe path, which restores
the strict-subset-of-cmd property everywhere except the documented cwd case.

PATHEXT is read from the child's env and joined into the cache key, since it
now changes the answer. Costs one stat per PATHEXT entry per node-less
directory, paid once per process behind the cache.

OrcaWinandOrca Worker fba90e017c fix(windows): copy the daemon host exe verbatim instead of renaming it (MDE T1036) (#17865)
* docs(windows): document the EDR signal surface

Six Microsoft Defender for Endpoint incidents fired against Orca 1.4.192 in
eight days on one enterprise Windows 11 / Intune tenant. All six were
behavioural process-tree scoring, not signature hits; two escalated to
multi-stage incidents mapped to ATT&CK Execution and Collection.

Add a reference doc mapping each attack-technique-shaped behaviour to the code
that produces it and to why it exists: the renamed daemon image (T1036), the
per-process PEB read, encoded policy-bypassed PowerShell (T1049), caret-escaped
cmd.exe lines, and computer-use screen capture plus runtime-compiled MSIL
(T1113). Records that signing is not the gate -- reputation is signer plus
hash-keyed prevalence -- and carries the two evidence gaps the report noted.

Adds an engineer checklist, deployment guidance for admins (AV path exclusions
do not suppress EDR behavioural alerts; an MDE alert suppression rule does), and
an explicit pre-deployment warning about computer use.

* docs(windows): correct the PowerShell flag inventory and admin paths

Review corrections to the EDR posture doc.

The "encoded, policy-bypassing PowerShell" list conflated three different
shapes and was incomplete. Split it into the three tiers an EDR actually scores
differently -- bypass plus encoding, encoding alone, and bypass alone -- and add
the sites it missed, including windows-mobile-firewall.ts, which encodes a
script and launches it elevated through Start-Process -Verb RunAs. system-fonts.ts
(-Command) and desktop-script-provider-bridge.ts (-File) were listed as encoded
and are not. Notes that a raw grep under-reports, because the hook sites reach
-EncodedCommand through wrapWindowsPowerShellEncodedCommand.

Attribute the in-payload Set-ExecutionPolicy move to #16576 rather than to
#16003's measurement, which keyed on -WindowStyle Hidden + -EncodedCommand, and
record that the launcher's own tradeoff is unverified on a real box.

Admin guidance was missing two ways a suppression rule pinned to one full path
misses real activity: the .staging-<hex> sibling that exists mid-update, which
is when the update-cluster incidents fire, and the userData fallback when
LOCALAPPDATA is unset.

Also: state the measurement conditions on the process-table timings, note that
Hermes has surface even though we have no telemetry for it, note that the
uninstaller names are electron-builder-generated and in no repo file, drop a
volatile line count, and mark the per-operation computer-use shape as being
addressed by an unmerged change. Drops the duplicated AGENTS.md section, keeping
the indexed bullet.

* docs(windows): reconcile the EDR posture doc with the shipped remediation

Three claims in this doc became false once the rest of the Windows EDR set
landed, and two told engineers the opposite of what the release does.

The process-table section still described one shared snapshot taken with
`Memory | CommandLine | CreationTime`, argued that splitting the cache per
field set "would restore exactly the fan-out it exists to prevent", and
concluded the shape was unfixable because "the information is only in the
PEB". The split shipped (identity opens no handle at all), `Memory` is
retired, and the command line now comes from the kernel through
`ProcessCommandLineInformation` -- `ReadProcessMemory` is absent from the
compiled addon and a ratchet asserts it against the import table. An engineer
reading the old text would have concluded both fixes were dead ends.

The PowerShell site inventories were stale in three of four lists: the port
scan went native, every `-ExecutionPolicy Bypass` + `-EncodedCommand` pair
was dropped as a measured no-op, and of the unencoded-bypass list only
`wsl-cli-scripts.ts` survives. Regenerated against the merged tree, including
the sites that reach the flag through `wrapWindowsPowerShellEncodedCommand`
and never spell it, which a raw `rg` misses.

Incident-evidence sections are left alone: they record what the tenant observed
on 1.4.192, not what the code does now.

* fix(windows): copy the daemon host exe verbatim instead of renaming it

Microsoft Defender for Endpoint flagged `orca-terminal-daemon.exe` as MITRE
T1036 (Masquerading): Orca copied its own `Orca.exe` into %LOCALAPPDATA% under a
different name, specifically so the NSIS updater's `taskkill /IM Orca.exe` could
not match, then ran it detached. Because that process is what every other flagged
action was attributed to, the name mismatch acted as a reputation multiplier on
unrelated findings.

The rename was never what made the daemon survive. In app-builder-lib 26.15.3 the
installer's FIND_PROCESS/KILL_PROCESS select processes whose image path is under
$INSTDIR; `taskkill /IM` is only the fallback for hosts where PowerShell is
missing or blocked. Survival is a property of the path, and
%LOCALAPPDATA%\Orca\daemon-host is outside $INSTDIR whatever the file is called.

Derive the host exe name from process.execPath so the copy is byte-for-byte,
name included — it keeps its Authenticode signature and carries no renamed-image
signal. On the no-PowerShell fallback the daemon is now killed with the app and
terminals cold-restore, which is the documented pre-relocation outcome the update
harness already asserts, not a regression.

The uninstall macro no longer needs a distinct name to find the daemon; it kills
the app's own image name (plus the legacy name, for hosts left by older builds).

Adds docs/reference/windows-daemon-host-relocation.md with the survival contract,
the rejected alternatives and their measured costs, and the invariants to keep.

* fix(windows): apply daemon-host relocation review corrections

Scope the uninstall taskkill to the current user with `/FI "USERNAME eq
%USERNAME%"` via cmd.exe, matching upstream's per-user KILL_PROCESS — without it
an elevated machine-wide uninstall reaches another logged-on user's session, so
the "no collateral" claim in the comment was overstated.

Comment the rmSync-before-publish: Windows refuses to delete a running image, so
a live daemon already hosted in this version's dir (same-version reinstall, or a
dev channel reusing a version) throws and materialization fails open.

Doc corrections:
- The fallback selector is the full per-user `taskkill /F /IM "<app>.exe" /FI
  "PID ne $pid" /FI "USERNAME eq %USERNAME%"`, not a bare `taskkill /IM`.
- The probe reads `Get-ExecutionPolicy -Scope Process`, not the effective policy,
  and GPO writes MachinePolicy/UserPolicy — so GPO-managed hosts take the primary
  path-scoped branch. Narrow the fallback triggers accordingly.
- Drop the Authenticode sentence: the old name was equally byte-identical and
  equally signed, so a filename has no bearing on signature validity.
- Name the new update-abort path: the daemon now matches FIND_PROCESS, so on the
  fallback branch an unkillable host reaches the retry loop's MessageBox /SD
  IDCANCEL and Quits, aborting a silent update.
- Correct the customCheckAppRunning rejection. It is ~6 lines, not a rewrite; it
  is wrong because forcing the PowerShell branch where PowerShell is absent makes
  FIND/KILL silently no-op and leaves the real app running with files in use.
- Bound the win honestly: OriginalFilename is empty on the shipped binary, so the
  strongest T1036 indicator never fired, and the residual copy-and-run-detached
  shape still maps to T1036.005.

Reconcile docs/reference/windows-edr-posture.md, which documents the rename as a
live finding and would otherwise contradict this change. Content-only edit:
markdown under docs/reference/ is not oxfmt-formatted as a matter of practice and
nothing in CI gates it, so the file is left consistent with its neighbours.

* fix(windows): expand USERNAME in NSIS instead of spawning cmd.exe

The uninstall macro routed both taskkills through `"$SYSDIR\cmd.exe" /C` purely
so `%USERNAME%` would expand — two extra interpreter spawns on the uninstall
path, in a change whose whole point is not adding scored behaviour, and the
exact `cmd.exe /c` shape the new AGENTS.md EDR bullet warns about. NSIS reads
the variable itself with ReadEnvStr, so the spawns buy nothing.

Verified on Windows 11 that the generated command line does what the filter is
there for: a copy of cmd.exe running as orca-nonexistent-probe.exe (pid 34244)
was terminated by `taskkill /F /IM "orca-nonexistent-probe.exe" /FI "USERNAME eq
<user>"` — SUCCESS, exit 0, process gone.

Guarded on an empty USERNAME because the degenerate case is silent: taskkill
rejects an empty filter value outright ("The search filter cannot be
recognized") and kills nothing, which would leave exactly the orphaned daemon
this macro exists to reap. `*` is rejected as a filter value too, so there is no
branchless spelling. With no USERNAME to scope by it kills unfiltered, as the
macro did before the filter was added. Stack stays balanced: three pushes, two
nsExec pops, three restores.

Also strike the last stale row in windows-edr-posture.md's remediation table.
"Copying our own image under a different name" read as outstanding work; it is
done by this change, so the row now points at the relocation doc. Same class of
staleness as the section reconciled in the previous commit, and git would not
have flagged it either.

* fix(windows): port the daemon-host uninstall sweep into the live NSIS include

The uninstall macro this branch rewrote lived in config/nsis/daemon-host-uninstall.nsh,
which main no longer includes: #17906 consolidated every Windows installer hook into
config/nsis/orca-installer-hooks.nsh because electron-builder accepts exactly one
`nsis.include`. Merged as-is, the rewritten macro would have been dead code while the
shipped uninstaller kept running main's stale sweep — `taskkill /F /IM
orca-terminal-daemon.exe`, which matches nothing now that the relocated host is a
verbatim Orca.exe copy. The RMDir that follows then cannot delete the running image, so
a live orphaned daemon and its ~224 MB tree would survive every uninstall.

Ported into the live include: the ${APP_EXECUTABLE_FILENAME} kill, the USERNAME filter
that keeps an elevated machine-wide uninstall out of another logged-on user's session,
and the register save/restore around both. The legacy orca-terminal-daemon.exe kill
stays so hosts left by older builds are still reaped.

The ratchet that was meant to catch exactly this pinned only the legacy image name,
which main's stale macro already satisfied, so it passed both ways. It now asserts the
app-exe kill and the USERNAME filter, against comment-stripped script — the prose above
the macro names both image names, so a toContain over the raw file proves nothing.

eight days on one enterprise Windows 11 / Intune tenant. All six were
behavioural process-tree scoring, not signature hits; two escalated to
multi-stage incidents mapped to ATT&CK Execution and Collection.

Add a reference doc mapping each attack-technique-shaped behaviour to the code
that produces it and to why it exists: the renamed daemon image (T1036), the
per-process PEB read, encoded policy-bypassed PowerShell (T1049), caret-escaped
cmd.exe lines, and computer-use screen capture plus runtime-compiled MSIL
(T1113). Records that signing is not the gate -- reputation is signer plus
hash-keyed prevalence -- and carries the two evidence gaps the report noted.

Adds an engineer checklist, deployment guidance for admins (AV path exclusions
do not suppress EDR behavioural alerts; an MDE alert suppression rule does), and
an explicit pre-deployment warning about computer use.

* docs(windows): correct the PowerShell flag inventory and admin paths

Review corrections to the EDR posture doc.

The "encoded, policy-bypassing PowerShell" list conflated three different
shapes and was incomplete. Split it into the three tiers an EDR actually scores
differently -- bypass plus encoding, encoding alone, and bypass alone -- and add
the sites it missed, including windows-mobile-firewall.ts, which encodes a
script and launches it elevated through Start-Process -Verb RunAs. system-fonts.ts
(-Command) and desktop-script-provider-bridge.ts (-File) were listed as encoded
and are not. Notes that a raw grep under-reports, because the hook sites reach
-EncodedCommand through wrapWindowsPowerShellEncodedCommand.

Attribute the in-payload Set-ExecutionPolicy move to #16576 rather than to
#16003's measurement, which keyed on -WindowStyle Hidden + -EncodedCommand, and
record that the launcher's own tradeoff is unverified on a real box.

Admin guidance was missing two ways a suppression rule pinned to one full path
misses real activity: the .staging-<hex> sibling that exists mid-update, which
is when the update-cluster incidents fire, and the userData fallback when
LOCALAPPDATA is unset.

Also: state the measurement conditions on the process-table timings, note that
Hermes has surface even though we have no telemetry for it, note that the
uninstaller names are electron-builder-generated and in no repo file, drop a
volatile line count, and mark the per-operation computer-use shape as being
addressed by an unmerged change. Drops the duplicated AGENTS.md section, keeping
the indexed bullet.

* docs(windows): reconcile the EDR posture doc with the shipped remediation

Three claims in this doc became false once the rest of the Windows EDR set
landed, and two told engineers the opposite of what the release does.

The process-table section still described one shared snapshot taken with
`Memory | CommandLine | CreationTime`, argued that splitting the cache per
field set "would restore exactly the fan-out it exists to prevent", and
concluded the shape was unfixable because "the information is only in the
PEB". The split shipped (identity opens no handle at all), `Memory` is
retired, and the command line now comes from the kernel through
`ProcessCommandLineInformation` -- `ReadProcessMemory` is absent from the
compiled addon and a ratchet asserts it against the import table. An engineer
reading the old text would have concluded both fixes were dead ends.

The PowerShell site inventories were stale in three of four lists: the port
scan went native, every `-ExecutionPolicy Bypass` + `-EncodedCommand` pair
was dropped as a measured no-op, and of the unencoded-bypass list only
`wsl-cli-scripts.ts` survives. Regenerated against the merged tree, including
the sites that reach the flag through `wrapWindowsPowerShellEncodedCommand`
and never spell it, which a raw `rg` misses.

Incident-evidence sections are left alone: they record what the tenant observed
on 1.4.192, not what the code does now.

Neil 8ac1c6e2ac perf(git): bound ref and worktree scans (#17655)
* perf(git): bound ref and worktree scans

* fix(repo-search): clamp oversized ref limits

* fix(worktree): keep strict worktree listing unshared

The shared-scan re-export flipped every `listWorktreesStrict` caller from an
isolated subprocess to the coalesced scan. `git worktree prune` in the removal
recovery path does not bump the scan generation, so a post-prune verification
could join a pre-prune scan, see the stale row, and report a successful removal
as a stale registration. The same gap defeats the post-archive-hook rechecks
that exist to catch an external Git client locking the row.

Restore the unshared export and make coalescing opt-in via
`listWorktreesSharedStrict`, which existing callers already use deliberately.

* fix(git): separate a proven absent ref from a failed probe

`show-ref --verify --quiet` exits 1 for a missing ref, but so does `wsl.exe`
when its own launch fails, so reading any exit 1 as absence collapsed
`unverifiable` into `exited`. A genuine miss prints nothing while a wrapper
failure always explains itself, so require empty stderr alongside the exit
code; a runner that reports no stderr at all keeps its exit-code contract.

That same signal removes a spawn regression: `show-ref` is a direct-git read
under WSL, and the runner retried any numeric exit through the user's
interactive login shell. The replaced `for-each-ref` exited 0 on a miss, so
absence never retried; every absent probe now would. Treat a quiet exit 1 as
Git control flow and skip the fallback.

Also narrow the hosted-review suffix fallback: the replaced
`refs/remotes/*/<base>` could not cross a slash, but `show-ref -- <base>`
matches at any depth, so `origin/feature/main` answered a query for `main`
and submitted a review against a base the provider rejects.

Refresh the real-binary compatibility contract to the shipped excludes, and
assert exact probe concurrency rather than an upper bound so a regression to
serial probing fails.

Neil 057fbfcffc perf(windows): read the process table natively instead of forking PowerShell (#15749)
* perf(windows): read the process table natively instead of forking PowerShell

Seven independent readers each forked powershell.exe to run
Get-CimInstance Win32_Process, with a wmic fallback that Windows 11 24H2
has removed. On a domain-joined host with PowerShell Transcription
enabled by policy, one of them running every ~2s recorded ~289GB across
1.4 million files (#15209). The same scan cost ~700ms and ran per pane
(#15036), and a Group Policy or AV block turned it into 'unavailable',
which callers read as 'no evidence' -- which is how a PTY tree survives
its own teardown (#9045, #10475).

A Toolhelp32 snapshot answers the same question with no child process.
Measured on Windows 11 with 1050 processes, p50/p95:

  pid+ppid+name          15.9 / 17.5 ms
  +memory +command line  30.6 / 33.7 ms
  Get-CimInstance         706 / 723  ms

Two upstream defects needed patching, both found by running it on real
hardware. The binding requires Spectre-mitigated libraries our agents do
not carry (node-pty is patched the same way). And enumeration stopped
after 1024 processes: on a host with 1051 the module returned exactly
1024, and the querying process was itself among the 27 missing -- a
truncated snapshot silently hides the descendants teardown is looking
for, which is the failure this whole change exists to remove.

Migrated: the foreground/descendant reader (the #15209 scraper and the
teardown identity gate) and the port scanner's PID attribution. NOT
migrated: the memory collector and three identity probes, which need
Win32_Process.CreationDate and have no native equivalent. Start time is
a proxy for identity anyway; an inherited job handle is the real answer,
so those belong with the job-object work rather than here.

Packaging follows the windows-native-registry contract exactly:
optional, absent from onlyBuiltDependencies so macOS/Linux never run
node-gyp, win32-only in the packaged runtime. Asserted by the existing
contract test, which also stops pinning a whole source literal that only
tested its own formatting.

* chore(process): ratchet the child_process allowlist down

windows-foreground-process-rows.ts no longer spawns anything, so its
allowlist line is stale. The guard fails on a stale entry as well as a
new one, precisely so a migrated file cannot keep a slot open and hide
the next regression in the same path.

* fix(ports): import the process-table reader the scanner uses

Missing import: the migration replaced the PowerShell call but the new
symbol was never imported, so tsc failed. Vitest transpiles without
typechecking, which is why the port-scanner suite stayed green.

* fix(deps): sync this branch's lockfile with its patch set

Same class as the fix on the tip branch: pnpm records a hash per patched
dependency, and this branch introduces the windows-process-tree patch
without its lockfile entry matching. Every job here failed at install
with ERR_PNPM_LOCKFILE_CONFIG_MISMATCH.

Verified with --frozen-lockfile, which is what CI runs and what my local
runs were not.

* test(relay): drive the relay's Windows fixtures from the native snapshot

Two relay cases fed a PowerShell CIM payload through a mocked execFile.
That reader is gone, so both failed -- deterministically, on every PR
run for this branch and the one above it.

I did not catch it because my own verification sweep was
'src/main src/shared config/scripts' and never included src/relay. The
relay is a first-class consumer of the process table; leaving it out of
the sweep is how a deterministic failure survived six review rounds.

Brennan Benson 5ca747dad0 docs(ssh): state the SSH execution boundary and pin the liveness vocabulary (#14971)
* docs(ssh): state the SSH execution boundary and pin the liveness vocabulary

Nothing under docs/ described how work splits between the client and an SSH
host, so agents and humans inferred it from error strings and got it wrong:
loss of contact was repeatedly reported as process death, which orphaned live
remote agents and cold-started duplicates over the same worktree.

Pins the vocabulary to the incumbent live/unverifiable/exited verdict from
unstopped-pty-verification so no synonym is introduced, records the one real
discriminator (all of a host's terminals drop together on link loss; one alone
means process exit), and lists the outstanding gaps with citations.

Tracked via the docs allow-list and linked from AGENTS.md, per the convention
in .gitignore.

* docs(ssh): cite the live restoreRequired site after it moved

The throw now lives in reattachSshPtySessionForSpawn; ssh-pty-provider.ts no
longer contains it. Caught by the worker fixing it, against a newer main than
the audit ran on.

* docs(ssh): require host evidence for liveness verdicts

* docs(ssh): keep boundary references stable

* docs(ssh): fence liveness evidence to its host identity

* docs(ssh): state replay and environment boundaries precisely

* docs(ssh): correct replay and platform boundary claims

* docs(ssh): describe headless runtime continuity accurately

* docs(ssh): distinguish authority from client metadata

* docs(ssh): describe pending fixes accurately

* docs(ssh): date the gap list and name the PR that closes each entry

The Known gaps section was accurate when written and becomes actively
misleading as its fixes land: it told a reader to go fix restoreRequired,
the missing unverifiable verdict, and the absent terminal-list host field,
three things now addressed by #14974, #14977 and #14973.

Mark the section as dated, require verification against current code before
acting on any entry, name the PR per entry, and move landed items out. Also
correct the two body claims that the landed fixes invalidated. The rules
above are durable; only this section rots.

* docs(ssh): make the boundary doc a durable ruleset, not an incident record

The Known gaps section was 18 of 93 lines enumerating specific defects from
one investigation, several already fixed by sibling PRs in the same batch. A
reference doc that needs a 'this section rots' warning is telling you the
section belongs somewhere else; those entries belong in issues.

Replace the six-row table of currently-lying signals with the method that
outlands any particular bug: ask whether the owning host produced the signal,
whether every PTY on the target went quiet together, whether the termination
event matches the current incarnation and generation, and whether a returned
status is actually a claim. Same for artifacts - state what ls-remote and a PR
head each do and do not prove, rather than listing which command is currently
wrong.

Nothing here goes stale when the open fixes land.

OrcaWinandOrcaWin 3a9f40ed70 fix(wsl): read machine output from a fenced login shell (#15290)
* fix(wsl): read machine output from a fenced login shell

Orca runs WSL reads through the distro's *interactive* login shell so
PATH matches the user's own terminal (nvm, mise and asdf only install
into rc files interactive shells read). An interactive shell also runs
the distro's rc/motd, and stock Ubuntu 24.04 writes its "run a command
as administrator" hint to stdout -- no user customization required.

Every caller parsing that stream was reading the banner as data:

  statPath  -> "To run a command as administrator...\n\ndirectory"
  readPath  -> banner prepended to the contents of every file read
  preflight -> banner prepended to `gh --version` / auth output

`.trim()` cannot recover any of these, so a WSL worktree's file
explorer sees no valid entry types and file reads return junk.

Three call sites had independently grown their own marker to survive
this (`__ORCA_AGENT_PATH__`, `ORCA_WSL_GIT_READ_ENV_V1`, and a
`>/dev/null` fd dance), which is the tell that it belongs in one place.

Fence the payload once, in the shared builder, and hand callers a
reader that returns just their bytes. The fence carries a per-call
nonce so `cat`-ing a file that happens to quote a marker is not
truncated. Exit status is preserved, so the ENOENT mapping still works.

wsl-git-read-environment drops its bespoke marker and parsing.

* test(wsl): fence the login-shell path-lookup boundary test

It asserted a raw interactive login-shell read matched an absolute path,
so the distro rc banner made it fail on any stock Ubuntu. It is part of
the shell-contracts CI gate, where it skips on Linux and hid the break.

* docs(wsl): record the guest command-execution contract

Both failure modes are silent - the command runs, exits 0, and returns
the wrong bytes - so the rules need to live somewhere a reader will
find them before writing the next wsl.exe call site.

* fix(codex): fence the WSL Codex identity probe

buildWslCodexBinaryStamp reads the login shell's stdout positionally --
path before the first newline, version after -- through an interactive
login shell. On a stock Ubuntu the rc banner lands ahead of the payload,
so the first newline falls inside the banner and the stamp becomes
path="To run a command as administrator..." with the rest as version.
Both halves are non-empty, so nothing throws: the stamp is silently
wrong, and an unstable stamp reads as "the Codex binary changed" and
reissues the trust grant.

The identity script ends in `exec`, so it never writes a closing fence;
the reader returns everything after the opening one, which is exactly
this case.

buildWslCodexIdentityArgs becomes buildWslCodexIdentityProbe and returns
the reader with the argv so the two cannot drift apart. The other three
WSL Codex commands are deliberately left unfenced: availability is
exit-code only, and app-server/login hand stdout to a long-running
program.

* fix(wsl): harden the capture fence after review

- readStdout now takes the LAST opening fence, matching the lastIndexOf
  the wsl-git-read-environment marker used deliberately: a login shell
  can echo the command text before running it, repeating the fence.
- local-worktree-filesystem throws instead of falling back to raw stdout
  when the fence is missing. The fallback silently reinstated the bug
  being fixed -- statPath would return the banner as a file type and
  readPath would return banner+contents, with no signal. Preflight keeps
  its fallback; its matchers scan the whole blob and tolerate a prefix.
- The exit-status test asserted only that the script CONTAINS `exit $?`,
  which is true for any input and never executed those lines. It now
  runs a real distro and asserts status 2 reaches the caller, which is
  what statPath's ENOENT mapping depends on.
- Corrected the doc: a sed backreference has no `$`, so `--` never
  rewrote it. Replaced with the positional and shell-local cases that
  were measured to differ.

* fix(wsl): stop running a login shell for filesystem reads

statPath/readPath/rm run coreutils at standard paths and shell builtins.
They need nothing from the user's PATH, so there was never a reason to
start a login shell -- and starting one is what put the distro's rc/motd
on the stdout these callers parse.

Fencing that output treated the symptom. Using a plain `sh -c` removes
the cause: no profile, no rc, no banner, by construction. The fence and
its missing-fence error go away with it.

The fence stays where it is actually needed: the three places that must
run the user's shell to resolve their PATH (the preflight CLI probe, the
WSL git environment probe, and the Codex identity probe).

Net -12 lines.

Jinwoo Hong 92f928cf89 feat(terminal): add copy action to link popover (#13857) 2026-08-11 12:58:07 -07:00
Jinwoo Hong 06780260c0 test(remote-runtime): run an old client and an old server against current code (#12682)
Mixed versions are the normal state of the remote-server feature: users update clients and servers independently. Until now nothing tested that. Every cross-version claim was made by code reading plus unit tests with hand-written old/new shapes — enough to catch design problems, not enough to catch a real skew regression.

This runs the REAL protocol implementations from two builds against each other in one process: the actual host methods and RPC dispatcher on one side, the actual renderer multiplexer on the other, with a transport that reproduces the production asymmetry — each side decodes with its OWN codec and drops frames whose opcode it does not know. A frame survives only if the RECEIVING build understands it, which is what makes this level sufficient without launching two apps. The old side is a genuine checkout extracted from the release tag; the extracted client was confirmed to lack a symbol that exists only on main.

Journey: subscribe, first snapshot, input reaching the process, live output, hide/reveal snapshot, transport drop, resubscribe, input landing again — across old->new, new->old, and a current/current control. Every step ends on an observed-state barrier; no sleeps. The oracle asserts the recorded step list, the exact 16-frame named sequence, negotiated capabilities, the exact input the host wrote to the PTY, rendered content, and zero decoder-rejected frames. A host method the stub lacks is recorded by name and asserted empty, so a harness gap cannot masquerade as a wire break.

Detection is proven per violation shape, and it attributes each to the correct side: an unnegotiated opcode goes red only where a decoder would reject it, a removed published field goes red only where an old client consumes it, and a legal additive field stays green in all three pairings so the harness will not cry wolf on safe changes.

It also documents the three compatibility rules in docs/reference/remote-wire-compatibility.md, linked from AGENTS.md, since they previously existed only as folklore — notably that "decoders reject unknown opcodes" is true for the desktop decoder but NOT for mobile, which silently drops them.

Deliberately scoped: terminal stream only. The session-tab sync channel is not covered, nor agent-session publications, file/Git RPCs, mobile E2EE framing, or the relay transport. Two version points, so a regression introduced and reverted between them is invisible.

CI selection was verified rather than assumed — `vitest list` confirms 0 matches under the shard's exclude and 4 under the dedicated job — because a lane silently running zero tests is precisely how a host-side defect escaped CI earlier in this series. Closes STA-3469.

OrcaWinandOrcaWin ed7849eb7b fix(worktrees): stop silently switching existing Windows setup scripts to Git Bash (#12406)
* fix(worktrees): stop silently switching existing Windows setup scripts to Git Bash

#6967 derived the Windows setup-runner shell from `terminalWindowsShell`. On
upgrade, any Windows user whose terminal preference resolved to Git Bash had
their existing `orca.yaml` setup script (and issue command) handed to bash
instead of cmd.exe. Scripts authored against the cmd runner — `copy`, `xcopy`,
`set VAR=value`, `if errorlevel 1`, `%VAR%`, backslash paths — broke with no
migration and no warning, and the failure looked like Orca broke the project.

The conflation is also wrong in the steady state: a terminal preference is
per-user, so two people on the same repo got different interpreters for the
same orca.yaml and no project could write a setup script that worked for all
of its Windows contributors.

The interpreter is now a property of the script, declared the standard way:
a leading `#!` line. Native Windows keeps the historical `.cmd` runner unless
the script declares a POSIX shell, so no existing script changes behavior.
`resolveSetupRunnerShell` keeps its role as the feasibility gate — a bash
runner still requires the terminal to resolve to Git Bash, since the launch
command is typed into that shell and uses MSYS `/c/...` paths.

`buildWindowsRunnerScript` now drops a leading `#!` line rather than `call`ing
it, so a declared-bash script that falls back to cmd (Git Bash missing) fails
on a real setup line instead of aborting on errorlevel at line one.

WSL worktrees, POSIX platforms, and SSH hosts are untouched.

* fix(worktrees): keep the cmd setup runner launchable from a Git Bash pane

Adversarial review of this PR found that pinning the runner format per script
reopened issue #6896 one layer down.

- `WorktreeSetupLaunch.shell` had been redefined to mean "the format the runner
  file was written in". `resolveSetupRunnerCommand` consumes it as "the shell
  that types the launch command", so a Git Bash terminal with a batch setup
  script produced `cmd.exe /c "C:\...\setup-runner.cmd"` typed into a bash pane,
  where MSYS rewrites the `/c` switch into a drive path: cmd opens interactively
  and setup never runs. `shell` is the terminal's family again; the runner file's
  .cmd/.sh extension carries the format, and a batch runner launched from a POSIX
  pane reuses the existing PowerShell ProcessStartInfo launcher.
- The cmd runner dropped a leading `#!` line and ran the rest as batch, so a bash
  script reaching cmd (PowerShell/cmd terminal, or any SSH-to-Windows host) got
  its interpreter-agnostic prefix executed before failing mid-way. It now prints
  why and exits 1 without running anything.
- A `#!` line's option flags were discarded: `#!/usr/bin/env -S bash -euo
  pipefail` lost pipefail because the runner is launched as `bash <path>`. The
  generated posix runner now replays declared flags via `set` and drops the
  duplicate interpreter line.
- Docs cover the per-user setup command in repository hook settings, which goes
  through the same `#!` rule, and describe what the `#!` line does and does not
  select.

Tests: composed launch command for a POSIX pane + cmd runner (hooks, shared
runner command, setup sequencing gate, observed-setup signal), the cmd runner's
shebang refusal, and shebang flag replay. Each fails with the source reverted.

* fix(worktrees): replay only real `set` flags and keep the gate in the pane's shell

Two round-2 review findings:

- `#!/bin/bash -l` replayed `set -l`, which exits 2 and aborted the runner under
  its own `set -e` before a single setup line ran (all platforms). Only the flags
  `set` documents are replayed now; a bare `-o` with no option name is dropped
  instead of dumping the shell-option table.
- The wait-for-setup gate picked its language from the runner file, so a batch
  runner launched from a Git Bash pane got the PowerShell gate while the agent
  startup command was already POSIX-quoted — `Invoke-Expression` cannot parse
  `'\''`. The gate now follows the pane; the runner still launches through the
  ProcessStartInfo launcher, never through bash.

Neil a0944cc129 fix(linux): restore Ubuntu 20.04 launch — pin node-pty glibc symbols + add glibc/libstdc++ packaging gate (#9902) (#10019)
* fix(linux): restore Ubuntu 20.04 launch by pinning node-pty glibc symbols (#9902)

The bundled node-pty pty.node is compiled from source in release CI on
ubuntu-latest (glibc 2.39). glibc's 2.32-2.34 libpthread/libutil merge
relocated openpty/forkpty (GLIBC_2.34) and pthread_sigmask (GLIBC_2.32)
into libc under new symbol versions, so the from-source build bound to
versions absent on Ubuntu 20.04 (glibc 2.31). The main process imports
node-pty at startup, so the app crashed on launch. pty.node is the sole
blocker (Electron needs GLIBC_2.25; other native modules <= 2.17).

- Patch node-pty: a .symver shim pins the 3 symbols to their pre-merge
  version (GLIBC_2.2.5 x64 / GLIBC_2.17 arm64), and Linux-only ldflags
  force libutil.so.1/libpthread.so.0 back into DT_NEEDED. Guarded to
  Linux; macOS/Windows untouched.
- Add a packaging gate (verify-linux-glibc-floor.cjs, afterPack): reads
  each bundled native binary's objdump -p version needs and fails the
  Linux build if any strong GLIBC_/GLIBCXX_/CXXABI_ node exceeds stock
  Ubuntu 20.04 (glibc 2.31 / GLIBCXX_3.4.28 / CXXABI_1.3.12). Catches
  GLIBC_ABI_DT_RELR, rejects GLIBC_PRIVATE, skips weak needs, fail-closed.
- Docs + tests; the lazy sherpa-onnx speech prebuilt (GLIBCXX_3.4.29,
  never loaded at launch) is a documented libstdc++-floor exemption.

* fix(linux): assert DT_NEEDED provider deps in the glibc-floor gate

Harden the packaging gate (flagged in adversarial re-eval): the version-floor
check alone can false-pass if the patch's forced `-l:libutil.so.1` ever silently
drops — the pinned openpty@GLIBC_2.2.5 still resolves from libc's compat alias at
build time, but fails to load on Ubuntu 20.04 where openpty/forkpty live only in
libutil. The gate now also asserts that any binary importing openpty/forkpty
keeps libutil.so.1 in DT_NEEDED. Validated on a real symver-pinned .so with
libutil dropped (now fails) vs. present (passes). Documents the recommended
real-host smoke-test follow-up.

Neil 533992bdda fix(git): cache unsupported capabilities per host (#8109)
* fix(git): cache unsupported capabilities per host

Old Git worktree, ref-search, and merge-tree fallbacks retried unsupported flags on recurring operations, flooding subprocess traces. Centralize capability probing per native, WSL, and SSH execution host, coalesce concurrent probes, and retry periodically for in-place Git upgrades.

* fix(git): recognize real old-Git merge-tree rejection

* test(git): enforce real binary compatibility matrix

* fix(ci): preserve Git compatibility test ownership

* fix(git): retain supported capability state

NeilandOrca f311307560 Add max-lines ratchet CI gate to block new line-limit bypasses (#7608)
oxlint already fails any file over max-lines that is not suppressed, so the
only way to grow past the budget is to add an eslint/oxlint-disable max-lines
comment or a per-file max-lines bump in mobile/.oxlintrc.json. This adds a CI
gate that freezes the current set of suppressions (config/max-lines-baseline.txt,
355 grandfathered entries) and fails the build when a NEW one appears — with a
loud, actionable message pointing at 'split the file'. Existing oversized files
are untouched; the baseline may only shrink (pnpm check:max-lines-ratchet --prune).

Wired into the root lint script and as a dedicated pr.yml step. Unit-tested
(15 cases) and verified against all three failure paths + clean-tree pass.
