Neil 5fed670a50 fix(rebuild): refuse to compile node-pty source that lacks the MSYS breakaway denial (#21968)
The addon gate already rejects a conpty.node without the L"msys-2.0.dll"
marker, in the Electron probe and after the rebuild. But the rebuild compiles
whatever node_modules/node-pty holds, and pnpm only materializes that from the
patch at install time. On a Windows dev checkout whose node_modules predated
the denial, --force compiled for minutes, rewrote conpty.node byte-identical
and unpatched, and the gate then advised "rebuild from source" -- the step
that had just run.

Read src/win/conpty.cc before compiling. If it lacks the literal, stop before
the rebuild and say to run pnpm install, which re-applies the current patch.
An absent source file is not judged; the addon gate still reads the binary.

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 5127d1eb3b refactor(windows): vendor the registry addon as @orca/windows-registry (#20438)
* refactor(windows): vendor the registry addon as @orca/windows-registry

windows-native-registry@3.2.2 was last published in 2023 by a single
maintainer. Orca called two of its exports, both read-only, so the whole
dependency is replaced by a local N-API addon under native/.

The vendored addon is read-only by construction: setValue, createKey and
deleteKey are gone, so RegDeleteTreeW no longer ships in the app. Two
upstream defects are also fixed rather than carried over — the name/data
scratch buffers were file-scope statics that concurrent reads would
scribble over, and createKey/deleteKey called .c_str() on a temporary.

Build wiring keeps the existing shape: still an optionalDependency gated
to win32, still excluded from pnpm's allowBuilds so only Orca's own
Windows rebuild runs node-gyp for it, still copied into the packaged
resources. The CI native caches now key on the vendored sources so an
addon.cc edit cannot restore a stale .node.

* test(windows): check the vendored registry addon against reg.exe

The addon is vendored source, so no upstream release proves it still
decodes values the way Orca's PATH readers expect. reg.exe is the only
independent oracle on the box.

* ci(windows): register the registry addon test on the Windows runner

A Windows-gated file self-skips on ubuntu, so without both registrations
it reports success while running on no machine at all.

* fix(build): link the registry addon as a workspace package, not file:

As a `file:` dependency pnpm re-resolved and re-linked the package on
every install, including `--frozen-lockfile` (measured: "added 1" on a
repeat no-op install). That virtual-store churn ran concurrently with
node-gyp reading the same tree and cost @vscode/windows-process-tree its
binding.gyp mid-rebuild, failing package (windows) whenever the native
cache hit and only that module needed building. The linux packaging job
hit the same race from the other side, as a pnpm staging move failure.

A workspace link resolves once and leaves the store alone; repeat
installs are now 55ms no-ops. native/windows-registry is listed
explicitly so `packages:` still does not auto-discover mobile/.

* fix(build): stop tracking node-gyp output for the vendored addon

The build/ tree is generated per host and ABI; the committed copy was
macOS-specific gyp scaffolding from a local build and would have shipped
stale Makefiles to every checkout.

* chore: ignore the vendored addon's node-gyp bin output too

node-gyp also emits bin/<platform>-<abi>/ beside build/; both are per-host
generated output that must never be committed.

a899f92402 feat(windows): enable structured Codex chat on native Windows (#18519)
* feat(native-chat): enable Windows structured sessions

* fix(codex): prove native Windows process identity

* style(codex): format Windows session seam

* fix Windows structured Codex admission

* fix(windows): reprobe missing process identity capability

* fix(windows): decide folder-workspace WSL routing before the click

Review found pathUsesWslUnc exported but unused, and the folder composer
hardcoding worktreeUsesWslPath:false. Together those meant a folder picked
under a \\wsl.localhost\ parent routed to structured chat, then got refused
by the host and fell back AFTER the click -- which defeats the lane's own
design goal that create cannot fail after the click.

The group's parentPath is in scope at submit and the workspace is created
under it, so the parent decides WSL-ness pre-click. Wires pathUsesWslUnc
there and adds tests for the helper, including the unhydrated-store case
that previously threw.

* fix(windows): collapse the gate derivation to one call, restoring max-lines

CI static analysis failed: launch-agent-in-new-tab.ts crossed the 300-line
oxlint ceiling. Adding a max-lines disable is forbidden, so the two gate
derivations collapse into one readWindowsStructuredGateInputs() call --
a store-backed site now adds one line and one import name instead of two.
Better shape anyway: one derivation entry point rather than two reads a
call site must remember to pair.

* fix(windows): engage the legacy fallback when the host THROWS a refusal

Review found a P1 this merge composes: neither parent could reach it. At the
lane head the only structured entry was launch-agent-in-new-tab (full
store-backed WSL check); on main all win32 was refused. The merge enables
win32 in creation flows that pass no projectRuntime, so a WSL folder
workspace, a WSL-configured repo, or a repair-required runtime now routes
structured -- and the host refuses correctly, but by THROWING rather than
returning {ok:false, refusal}.

Callers engage their legacy-terminal fallback on the refusal CLASS, so an
unmapped throw arrives as a generic RPC rejection: no fallback, empty
workspace, error toast, prompt stranded in the launch outbox. Pre-merge the
same action opened a legacy terminal agent.

Map the host's thrown definitive refusals onto the refusal class at the
launch boundary, so every creation flow -- present and future -- degrades to
the legacy terminal instead of stranding. Narrow predicate: unrelated
failures (ECONNRESET, empty message, non-Error) still propagate untouched.

Ablation-proven: removing the mapping reddens the fallback test.

* fix(windows): teach the mobile RPC double the status probe the lane added

CI's first-ever run on this lane caught a pre-existing lane defect. The lane
changed status.get to resolve through
runtime.getStatusAfterWindowsProcessStartTimeProbe(), but never taught the
mobile-surface runtime double about it, so status.get failed for mobile
clients with "not a function". The lane's own test list did not include this
file and the lane had zero CI, so nothing ever ran it.

The real runtime always implements the method; the double omitted it.

* chore: merge current main and regenerate the localization runtime catalog

CI static analysis failed on a stale en-runtime-required.json: main added
onboarding integration-capability keys, and the generated catalog is checked
against the PR MERGE result, not the branch alone -- so it read clean locally
while failing in CI. Merging current main (90780acb85) and regenerating.

Gates after the merge: pnpm tc 0, oxlint 0, changed-code quality 0/56,
7 gate/lane test files 69 tests green.

This reverts commit 81bfca0007.

This reverts commit 47abbd354a.

* fix(windows): refuse structured chat in a paired web client

Reverts the two review-loop commits (restoring a tree byte-identical to the
validated head) and closes the hole they were aiming at, without their cost.

A paired web client's `platform` describes the browser's machine, not the host
that will run the agent, so the Windows gate cannot be evaluated there. Before
this, a browser on macOS driving a Windows runtime read "not win32", skipped the
creation-time proof entirely and allowed structured chat — fail-OPEN, the
dangerous direction, bypassing the guarantee this lane is built on.

`isWebClient` is a required input like the other gate fields, so the compiler
enumerated all seven call sites. Refusal is synchronous and fail-closed: no
async round-trip, no null window, no cache to invalidate — unlike keying on an
asynchronously-fetched host platform, which would have made every desktop
launch wait on a round-trip to fix a paired-web-only hole.

Paired web therefore gets the legacy chat until the host publishes eligibility
itself; that is the proper fix and belongs in its own PR.

Ablation-proven: removing the guard reddens both refusal tests; the
desktop-unaffected test is a preservation check and passes either way.
Gates: tc 0, oxlint 0.

Known open: repos-onboarding-folder-startup.test.ts fails on this branch and
passes on plain main — under investigation, NOT caused by this commit.

* test(onboarding): mock the web-client check the store path now reaches

The web-client refusal added `isWebClientLocation()` to the launch-route
inputs, which this suite's store path reaches while adding the FIRST folder.
The suite stubs `window` as `{ api }` with no `location`, so the function
cleared its `typeof window === 'undefined'` guard and then threw on
`window.location.pathname`.

That threw inside addNonGitFolder's own catch, so folder-1 never activated;
folder-2 then returned early (a project already existed) before reaching the
call at all, leaving exactly one activation with no startup seed.

Test artifact, not a product defect: a real renderer always has
`window.location`, so the seeding path is intact for users. Mocking the module
is the convention 7 other suites already use, and keeps product code free of
defensive branches that only exist to satisfy a stub.

Ablation-proven: removing the mock reproduces the original failure exactly.

* fix(renderer): make the web-client check total over a partial window

isWebClientLocation() guarded `typeof window === 'undefined'` and then assumed
`window.location` existed. A window stubbed without a location cleared the
guard and threw on `.pathname`.

That matters because this branch put the call on the launch-routing path,
where the throw is swallowed by the caller's catch and silently becomes a
FAILED LAUNCH rather than a visible error. CI caught it as 9 failures in
launch-work-item-direct.test.ts.

I previously "fixed" this by mocking the module in the one suite I knew about.
That was whack-a-mole against an unbounded set, and it missed this one. The
defect is the partial-window assumption, so fix it there: the mock is removed
from the onboarding suite and both suites now pass on the hardening alone.

Ablation-proven: reverting to the unguarded form reddens 11 tests across the
new unit suite and launch-work-item-direct.

Gates: tc 0, oxlint 0, changed-code quality 0/58.

* Move Codex's Windows structured-chat eligibility onto the host createSupport probe

The renderer no longer decides Codex win32 eligibility: launchStructuredAgentSession
probes agentSession.createSupport for both providers, the host answers via
supportsCodexStructuredLocation (process start-time proof + WSL refusal), and the
create path re-checks live. Deletes the client-side windows gate module and its
routing inputs (windowsProcessStartTime, worktreeUsesWslPath, isWebClient, platform)
from six call sites. Splits killCodexAppServerProcessTree out of
codex-app-server-session to hold the max-lines ceiling without a disable.

* fix(ci): keep pnpm lockfile stable

* test(windows): align foreground snapshot flags

* Restore main's pane-snapshot flag contract

Main asks for CreationTime on both projections; this branch's hot-path
isolation went away with the async probe it served.

bfc6a262a7 fix(windows): read command lines from the kernel, not each process's PEB (#17886)
* fix(windows): read command lines from the kernel, not each process's PEB

MDE incident D scored Orca for suspicious memory activity: the vendored
`@vscode/windows-process-tree` recovered every process's command line by
opening it with `PROCESS_QUERY_INFORMATION | PROCESS_VM_READ` and chaining
three `ReadProcessMemory` calls through the PEB and
`RTL_USER_PROCESS_PARAMETERS`. On a 750ms/2s cadence over the whole table that
is the credential-dumping primitive, whatever the intent.

Windows 8.1 added `NtQueryInformationProcess`'s `ProcessCommandLineInformation`
class (60), which returns the same string as a kernel-built `UNICODE_STRING`
under `PROCESS_QUERY_LIMITED_INFORMATION` alone. Electron's floor is Windows
10, so every supported OS has it. The PEB reader stays behind a process-wide
latch that only `STATUS_INVALID_INFO_CLASS`/`NOT_SUPPORTED`/`NOT_IMPLEMENTED`
can set; a pid that merely denied a handle does not re-arm it, because
`PROCESS_QUERY_INFORMATION` implicitly grants the limited right and so cannot
be obtained where the weaker open already failed.

The same hunk drops `PROCESS_VM_READ` from `GetProcessMemoryUsage` and
`GetCpuUsage`, which acquired it and never read an address space.

Measured on Windows 11 (514 processes), counted in-process by swapping the
addon's import table entries for counting stubs, per CommandLine scan:
`ReadProcessMemory` 1128 -> 0, desired access 0x0410 -> 0x1000, p50 12.7ms ->
9.3ms. Command lines were byte-identical on every process both readers
recovered (376/376, 379/379 across runs), including a 24,068-character argv
with quotes, non-ASCII and trailing whitespace, and a WOW64 target. Three
processes that refused the old rights granted the new one; none went the other
way.

* chore(deps): refresh the windows-process-tree patch hash in the lockfile

* fix(windows): drop the PEB fallback and detect the unpatched prebuilt

Review of #17886 found three ways the reader could still perform, or silently
resume, the primitive it exists to remove.

The class-missing latch was a permanent, process-wide, one-way downgrade back
to the PEB read, and any single target returning STATUS_INVALID_INFO_CLASS /
NOT_SUPPORTED / NOT_IMPLEMENTED could trip it. On an EDR-hooked ntdll -- the
entire premise of this change -- a hook that does not recognise class 60 would
have restored PROCESS_VM_READ plus three ReadProcessMemory per pid per scan for
the life of the process, unobservably, on precisely the machines this was
written for. The fallback is deleted rather than guarded: GetProcessCommandLine
now returns false and leaves the command line empty, which callers already
handle, so the addon imports no ReadProcessMemory at all.

That absence is what makes the property checkable on the artifact. The
published 0.8.0 tarball ships a loadable prebuilt built from unpatched source;
it is node-addon-api, so a bare require() accepts it, allowBuilds is false and
CI installs with --ignore-scripts, and a rebuild that soft-exits on a Windows
file lock leaves it in place. Source-text guards could never see it.
windowsProcessTreeAddonReadsProcessMemory() checks the compiled binary instead,
and is wired into the install check, the rebuild, and the relay build.

The repair itself never worked: `git apply` run inside a work tree prefixes
patch paths with the cwd-relative prefix, skips what does not match, and exits
0, so the branch always fell through to its own post-check throw. The package
dir is always under the project root, while the fixture that covered it was in
%TEMP%, outside any repo. Blinding git with GIT_DIR fixes it, and the test now
runs inside a real work tree.

Also from review: bounds-check the returned UNICODE_STRING against the
allocation (not the size the second query clobbers) and cap the probe so a
bogus length cannot bad_alloc a whole scan; test NT_SUCCESS explicitly; value-
initialize ProcessInfo, which left `memory` as stack garbage -- measured, 82
processes reported the same bogus working set; and correct a comment in
windows-process-table.ts that still described the command line as a PEB read.

Re-measured on Windows 11 (543 processes): ReadProcessMemory 1128 -> 0, with
the symbol absent from the import table so the IAT hook finds no slot to
count; desired access 0x0410 -> 0x1000 on all 543 opens; p50 13.5 -> 12.3ms;
405/405 command lines byte-identical including a 24,087-character quoted
non-ASCII argv and a WOW64 target; 3 processes recovered only by the new path,
0 only by the old.

* chore(deps): refresh the windows-process-tree patch hash in the lockfile

* test(scripts): stage a script's local imports into the native-runtime fixture

ensure-native-runtime.mjs gained an import of windows-process-tree-gyp-rebuild.mjs,
but the fixture copied only the script itself, so every case in the suite died
with ERR_MODULE_NOT_FOUND before reaching its own assertions. copyScriptWithLocalModules
already walks a script's co-located imports for exactly this reason -- its own doc
comment names this failure -- so use it rather than listing files by hand.

The two Windows cases still fail here, on a missing node-pty ConPTY runtime that
also fails on main; this only stops a resolution error from standing in front of
whatever they were meant to catch.

* fix(windows): route a locked stale addon to the Windows file-lock message

`pnpm install` with Orca running aborted with a raw EPERM stack. The stale-binary
guard -- which deletes an addon that still imports ReadProcessMemory so a skipped
rebuild cannot use it -- ran outside the try whose catch classifies Windows file
locks, and whose message is literally "Close running Orca/Electron/dev processes
for this worktree": exactly this situation.

Measured rather than assumed: rmSync against a loaded (memory-mapped) addon throws
EPERM, and `force: true` does not help, since it only swallows ENOENT. Cold copies
of the same file delete fine. So the delete threw a page before the handler that
knows what it means.

Moving the guard inside the try is the whole fix; the classifier already matches
the EPERM text. The new case runs the real script against a temp project whose
stale addon is held open by a live child process, and fails against the old
placement with the raw `syscall: 'rm'` stack the report described.

* feat(windows): warn once when command-line recovery is refused host-wide

Removing the PEB fallback removed a total-defeat vector, but it left a cliff: if
NtQueryInformationProcess(ProcessCommandLineInformation) is refused -- a hooked
ntdll that does not know class 60 -- every command line comes back empty and
agent identity matching silently degrades to image names. The addon still loads
and still enumerates, so every health check the app has stays green. A cliff
nobody can see is the failure mode this area keeps producing.

The querying process is the unambiguous probe. A process can always open itself
with PROCESS_QUERY_LIMITED_INFORMATION, so its own command line coming back empty
means the query is refused for every process -- not that some target denied a
handle, which is normal for roughly a quarter of the table. Keying on our own row
rather than a fraction means no threshold to tune and no false positive on a
hardened box where most processes deny.

One warning per session, gated on the CommandLine flag actually being requested so
a future identity-only reader cannot trip it. The suite's own SELF fixture gains a
command line for the same reason: a self row without one is the alarm, not a
detail.

* fix(windows): check the relay's staged addon at load, and answer tri-state

Two gaps in the ReadProcessMemory check, both about what it does not see.

It only ever looked at node_modules/@vscode/windows-process-tree. A relay host
has no node_modules of ours: it loads ./windows-process-tree.node staged beside
the bundle. The relay build asserts the symbol on the artifact it produces, but a
bundle and the addon beside it redeploy independently, so a host that has not
taken a new bundle keeps whatever binary is already there -- and the published
prebuilt is node-addon-api, so it binds cleanly and then walks every process's
address space. loadWindowsProcessTree now checks that file too and refuses it,
falling back to the CIM scan: slower, but not the thing an EDR quarantines a host
for. The predicate is duplicated rather than imported, because the config-script
copy is install-time tooling that drags in node-gyp and child_process, and this
module is bundled into the app and the relay.

And it returned false for a binary that is not there. All three callers happened
to be safe, but the name read as a safety predicate, so a future caller would take
a missing binary as verified. inspectWindowsProcessTreeAddon() now answers
clean/unpatched/missing over an explicit binary path -- which is also what lets
the relay's staged addon be checked at all -- and each caller states which state
it acts on.

Both are covered by cases that fail against the old code: without the load-time
check the unpatched staged addon is bound and the CIM fallback never runs, and
with 'missing' folded back into 'clean' the absence case fails outright.

* test(windows): load the addon in beforeAll, not at collection time

loadAddon() ran while the file was being collected, so on a Windows checkout with
no built addon the require threw before any case existed and took the seven
patch-text cases down with it -- cases that read only the patch file and need no
binary at all. Verified both ways against a deliberately unresolvable addon path:
at collection time vitest reports "no tests" for the file; from beforeAll the
seven text cases pass and only the three addon cases go.

* fix(deps): normalize the windows-process-tree patch to LF and let pnpm own its hash

`pnpm install --frozen-lockfile` failed on this branch on every platform with
ERR_PNPM_LOCKFILE_CONFIG_MISMATCH, which breaks CI and the release build.

Two coupled defects. The patch file was committed with CRLF -- 174 CR bytes,
against zero on main -- and `.gitattributes` pins `/config/patches/*.patch -text`
precisely so checkout cannot convert it, so those bytes reached every runner. And
pnpm hashes a patch **LF-normalized**, so the raw sha256 of a CRLF file is a value
pnpm never computes:

  raw sha256      322965470c05f63d8527f7d8e892ee26ee444136b66b57fd64c362a9f2ff05d1
  LF-normalized   f8ea245391c94da5770045aeea01fa6de466c2199c6ef46b5b769b398aa9823e

The lockfile carried the raw one, at all three sites. It is the only one of the
seven patches where the two digests differ, which is why the other six passed.

Normalized the patch to LF and took pnpm's own value from
`pnpm install --no-frozen-lockfile`; nothing here is hand-computed. With the file
LF-only the two interpretations coincide, so the lockfile, the contract test's
no-CR assertion and its hash assertion all agree at one number -- and
`config/scripts/windows-process-tree-patch-contract.test.mjs`, which was red on
this branch for the same reason, is green again. The lockfile diff is exactly the
three hash lines.

The regression check is the installer, not a digest. Two separate reviews
"verified" the shipped hash by recomputing sha256(patchBytes) and matching the
lockfile; both were wrong, because both repeated the same wrong assumption about
which bytes pnpm hashes. A check that reproduces the original mistake is not
independent. So the new case runs `pnpm install --frozen-lockfile --lockfile-only
--ignore-scripts` against a copy of the manifest, lockfile and patches, and
asserts exit 0 -- verified by deletion: restoring the shipped hash fails it with
the exact ERR_PNPM_LOCKFILE_CONFIG_MISMATCH from the branch's package (windows)
job.

Also corrected the `.gitattributes` comment claiming pnpm hashes patches
byte-for-byte. The `-text` setting is right -- `git apply` needs the exact bytes --
but that sentence is the claim that produced the wrong hash twice.

* ci(windows): run the process-tree patch suites in CI

Both suites only self-skip off Windows, so the binary-level check that the
addon carries no ReadProcessMemory passed vacuously in every lane.

* fix(windows): force core.autocrlf=input for the patch repair

My LF normalization of the windows-process-tree patch broke the `git apply`
repair path introduced in this PR. The two are coupled and I checked only one.

Those 174 CR bytes were not editor noise. They sat on exactly the pre-image
lines and nowhere else -- 107/107 in src/process.cc, 67/67 in
src/process_commandline.cc, 0 on every added or context line -- because
@vscode/windows-process-tree@0.8.0 ships those two sources as CRLF. Normalizing
the patch made its pre-image stop matching the file it is applied against.

Measured, reconstructing the true CRLF pre-image from the pre-normalization
blob and applying the current LF patch:

  core.autocrlf   plain   -c core.autocrlf=input
  true            exit 0  exit 0
  input           exit 0  exit 0
  false           exit 1  exit 0

`false` is Git's own built-in default and what "checkout as-is" selects in the
Git for Windows installer -- on this box the `true` that hides it comes from the
installer's system gitconfig, not from anything in the repo. There the repair
throws, ensureWindowsProcessTreeCommandLinePatch reports "still reads the PEB,
and repairing it ... failed", isWindowsNativeLockError does not match that text,
and `pnpm install` dies with no path forward.

Forcing the mode rather than `--ignore-whitespace`: both fix every cell and both
leave the applied file fully LF, but `input` relaxes line endings only, so a hunk
whose real content drifted is still rejected. The repair rewrites a
security-relevant source file; it should stay strict about everything except the
thing that is legitimately ambiguous.

Not reverting the patch to CRLF: windows-process-tree-patch-contract.test.mjs
(pre-existing on main) forbids CR bytes in it, and pnpm computes the same hash
either way. LF plus the forced mode is the end state.

The suite could not have caught this. The fixture built its pre-image from the
patch itself and joined with '\n', so fixture and patch agreed by construction on
any encoding -- once again a test that passes without its fix. It now emits the
CRLF the real package ships, and the case runs under both autocrlf modes pinned
through a temp HOME gitconfig, because the repair blinds git to the repo and so
reads global config. Verified by deletion in both directions: with the flag
removed the autocrlf=false case fails with the exact "still reads the PEB" dead
end while autocrlf=true still passes, and with the fixture back on LF all eight
cases pass with no fix present at all.

Also corrected the .gitattributes comment I added last commit. It said `git
apply` needs the bytes the patch was written against, which is now false -- the
pinned bytes are LF and the bytes it was written against are CRLF. That is the
same class of confident-and-wrong claim that produced the bad hash twice.

* fix(windows): assert the rebuilt addon, and install the patch for real in tests

Three follow-ups from review.

**The packaged binary had no check.** The relay build asserts its own artifact
and ensure-native-runtime asserts what it loads, but nothing looked at the addon
copied into the packaged app -- so a rebuild that silently produced the upstream
reader shipped. `rebuild-native-deps.mjs` now asserts `clean` on it after
`rebuild()`. This is also the caller D4's tri-state was missing: every existing
site branches on `=== 'unpatched'`, so `missing` still behaved exactly like
`clean` everywhere, which was the thing making it a state rather than a boolean.
Here both non-clean states fail, and they fail differently: after a rebuild that
reported success, an absent binary is a broken build, not an absence to shrug at.

The fake `rebuild()` had to start producing a binary for that to mean anything,
so it now emits stand-in bytes and takes `addon: 'clean' | 'unpatched' | 'none'`.
Verified by deletion: with the assertion removed both new cases pass.

**The frozen-install case could not see a patch at all.** `--lockfile-only`
resolves and never applies one, so its coverage stops at hash consistency. Added
a case that installs `@vscode/windows-process-tree@0.8.0` for real with the patch
and asserts the materialized `src/process_commandline.cc` carries the marker and
no longer carries `ReadProcessMemory` -- about 1.5s for the pair.

Correcting the brief on that one: it does **not** catch the `git apply` breakage
from the previous commit. Measured -- with `-c core.autocrlf=input` removed it
passes cleanly, because `pnpm install` uses pnpm's own patch applier and never
runs our repair script. What it does catch is a patch pnpm can no longer apply:
corrupting one pre-image line fails both cases. The repair path stays covered by
the CRLF fixture in rebuild-native-deps-node-pty.test.mjs.

Worth recording, since it decides whether the LF normalization was safe at all:
pnpm applies the LF patch to the CRLF tarball sources without complaint, and
materializes them as LF with the marker present and `ReadProcessMemory` absent.
The primary install path was never affected -- only the `git apply` fallback was.

**Dead timeout.** The frozen-install case passed `timeoutMs: 300_000` to the
spawn while vitest capped the case itself at 30s, so on a cold runner vitest
would have killed it first. Both cases now declare the budget they use.

* test(windows): route the frozen-install check through the pnpm invocation owner

The new patched-dependencies check hand-rolled a PATH walk naming 'pnpm.cmd',
which the windows batch shim spawn boundary ratchet rejects: pnpm-cli-invocation
already owns that decision for every other script, and its allowlist only
shrinks.

Reuse resolvePnpmCliInvocation for the command and prefixArgs, and the shared
resolveCliCommand for the presence check, so no shim name is spelled here. Its
`shell` flag is dropped because runProcessSync refuses it and already drives a
shim through the interpreter itself.

Neil f116d2ca2a test(ci): retry Windows teardown EPERM and restart evaluate misses (#17780)
Restart-survival polls treated a recycled renderer as a hard failure.
Wrap those evaluates so "Execution context was destroyed" is a pending
miss. Windows package-lane teardowns after a force-kill used rmSync
with force:true only, which does not absorb EPERM; put them on the
shared maxRetries:8 policy.

Neil b261f4005c fix(build): preserve Electron during binary repair (#17334)
* fix(build): preserve Electron during binary repair

* refactor(build): split native dependency fixtures

* fix(build): resolve one Electron install target for child and check

runElectronPackageBinaryInstall forced ELECTRON_INSTALL_PLATFORM/ARCH to the
host-derived rebuild target, clobbering inherited installer env, while the
parent usability check still honored the inherited value. A bare
`node config/scripts/rebuild-native-deps.mjs` under ELECTRON_INSTALL_PLATFORM=win32
on Linux therefore installed the Linux binary and then rejected it as
unavailable. Resolve the target once (CLI, ELECTRON_INSTALL_*, npm config, host)
and use it for both the child env and getElectronPlatformPath.

* fix(build): keep Electron install transaction cleanup best-effort

The finally-block rmSync could throw after a fully successful publish (Windows
EPERM when another process still holds the discarded old electron.exe open),
turning a correct install into exit 1. On the rollback path it could also
replace the in-flight publishError with an unrelated temp-dir error. Retry the
removal and downgrade a persistent failure to a warning.
