Neil 61337dfb33 chore(ratchet): gate event-loop-blocking calls in the daemon, PTY and orcad code (#34614)
* fix(daemon): read the PTY process table without blocking on terminal kill and resize

The terminal daemon force-killed a session by running ps and reading
/proc/<pid>/stat synchronously, and checked the resize foreground group
with execFileSync('ps'). A slow or wedged ps froze every terminal the
daemon serves for up to the ps timeout on each call.

Both paths now use the async process-table read (runProcess with a
timeout that kills the child). SubprocessHandle.forceKill may return a
promise; the termination controller awaits it so a refused signal still
releases the claim for a retry. A force-kill or SIGWINCH whose root
exits while ps runs signals nothing, since the captured groups could
already be recycled. ConPTY force-kill stays synchronous so dispose()
still sees the node-pty kill it must not repeat. The in-process
provider's app-quit sweep keeps the blocking variant. The ps dialect
and table readers move to posix-pty-process-table.ts.

* fix(daemon): address review on async PTY process-table reads

Guard only the root-pid fallback on exit so proven groups are still swept
after dispose, wait out at most one ps dialect probe, move the sync-launch
baseline entry with the table reader, and keep tests cross-platform.

* fix(daemon): keep the PTY open until an in-flight force-kill sweep finishes

A sweep whose root exits mid-read must not signal: the freed TTY may
belong to another terminal. Dispose therefore defers destroy() until the
sweep settles, so its hangup cannot end the root first.

* test(daemon): build the destroy-tracking PTY mock without a type assertion

Refs #34410
Refs #33870

* fix(pty): make the local graceful-deadline force-kill async and stub ps in tests

The in-process provider's graceful-deadline timer now uses the async
group sweep; the app-quit sweep and the root-signal path stay
synchronous. Tests that drove force-kill through fixture pids now stub
the async process-table read instead of querying the host, and a new
test pins that waiters do not chain behind a failed dialect probe.
Session ids are only read for rows on the root's terminal.

Refs #33870

* fix(pty): hold PTY teardown until an in-flight force-kill sweep settles

Orphan cleanup could destroy a local PTY while the graceful-deadline
sweep was still reading the process table, neutralizing its fallback
kill and hanging up the root first. Both the daemon handle and the
local provider now defer teardown through PendingPtyGroupSweep.

Concurrent force-kill callers in the daemon now await the shared
in-flight request, so a joiner's physical-exit budget starts after the
signals are sent and it sees their rejection.

Refs #34410
Refs #33870

* fix(pty): let disposal and orphan cleanup join the in-flight force-kill sweep

Session disposal now joins the controller's shared force-kill request
instead of starting a second sweep. Local orphan cleanup decides its
escalation only after a pending graceful-deadline sweep settles, so a
refused sweep is escalated before the handle is released rather than
leaving the retry with a neutralized kill.

Refs #34410
Refs #33870

* fix(daemon): SIGKILL live PTY groups before a shutdown deadline exit

The old synchronous sweep sent its signals before the shutdown deadline
timer could run; the async sweep can still be reading the process table
when it fires. The deadline now SIGKILLs each live session's process
group synchronously before exiting (node-pty roots lead their own
group), falling back to the root pid when the group kill is refused.
POSIX only.

* chore(ratchet): gate event-loop-blocking calls in the daemon, PTY and orcad code

The terminal daemon and orcad serve every pane from one event loop, so a
synchronous child launch or file write there freezes all of them. A new
count ratchet tracks execFileSync/spawnSync/execSync, runProcessSync,
appendFileSync and writeSync per file under src/main/daemon,
src/main/pty, src/main/runtime and src/main/orcad; counts may only go
down. It reuses the sync-spawn ratchet's import-aware call collector,
now extracted to gated-call-use-collector.mjs, so aliases, namespace
imports and re-exports count and same-named methods on other objects
do not.

OrcaWinandOrca Worker 4559c250b3 fix(windows): restrict secure files in-process instead of spawning icacls (#28135)
* fix(windows): restrict secure files in-process instead of spawning icacls

Every secure write on Windows spawned icacls.exe five times on the calling
thread (the Electron main thread for most stores): verify, /reset,
/inheritance:r /grant:r, verify, verify. Process creation under endpoint
security costs ~0.6 s each, so each write froze the UI for seconds (#26027).
The /reset + /inheritance:r pair is also what behavioural EDR scores as
ransomware tradecraft (#25583).

Add native/windows-security (@orca/windows-security): a small N-API addon
over advapi32 that reads and writes DACLs in-process. It exposes the token
user SID, a DACL read as SDDL, a DACL write (sync and on the thread pool),
a create-with-DACL file write, and an additive grant. Policy and
verification stay in TypeScript.

- writeSecureFile creates each temp file already carrying the protected
  user/SYSTEM/Administrators DACL (CreateFileW + SECURITY_ATTRIBUTES), reads
  it back once, and renames it. No ACL is modified on the write path and no
  process starts. Before: 5-7 spawns, 94-138 ms per write. After: 0 spawns,
  ~0.5 ms.
- A secure directory is verified once per process. It is rewritten only
  when verification fails, on the thread pool, because the write walks
  every descendant (~2 s on a 29k-entry userData).
- The verifier follows OpenSSH's rule: only the user, SYSTEM and
  Administrators may be granted anything, and the path must be protected
  (or, for a file, inherit from a secure parent). DACLs written by the
  icacls-era hardening pass unchanged, so there is no migration.
- If the addon cannot load, the write still happens and reports
  unrestricted, logged once. There is no icacls or PowerShell fallback.
- grantDirAcl, the startup userData grant, and the install-dir probe and
  package repair use the same addon, so whoami.exe and icacls.exe are no
  longer spawned anywhere at runtime.
- orcad's Windows slots ship the addon beside their bundles (built per
  arch, PE-machine checked). Its data-root privacy check fails closed, so
  without the addon a Windows orcad would not start.

Fixes #26027
Fixes #25583

* refactor(secure-file): harden existing Windows files through the sync lane

The read path called restrictWindowsPathSync directly and recorded success
itself; the existing sync lane already does both. One call site fewer.

* refactor(windows-security): one load, one rule, no fallthrough (review #28135)

- The descriptor parser is anchored, so a conditional ACE (its body holds
  parentheses) or anything else it cannot read fails closed instead of
  verifying the ACEs before it.
- findSecureDaclViolation is one flat rule: protected, allow rules only for
  the user, SYSTEM and Administrators (OpenSSH's ACE rule), and full
  control for the user. The inherits-from-a-secure-parent exception is gone:
  it accepted exactly what loosening the parent reaches.
- The addon and the user SID load once, behind one wrapper that adds the
  extended-length prefix to every path and runs async DACL writes to one
  path in order, so a startup grant cannot land after a re-lock and restore
  the broader DACL.
- With the addon loaded, a failed born-restricted create throws with the
  matching Node error code instead of falling back to a plain write.
- A grant leaves a NULL DACL untouched instead of turning 'everyone' into
  'only this SID'. WriteFile runs once and fails on a short write.
- The artifact create-intent store writes through writeSecureFile and drops
  its own temp writer, directory LRU and synchronous directory re-lock.
- Test seams the global fake makes redundant are gone.

* fix(packaging): fail a Windows build whose workspace addon binary is missing or foreign-arch

The @orca/windows-* workspace links exist on every host, so their presence
proved nothing: a missing or wrong-architecture .node only surfaced at
runtime, as unrestricted secure files or an orcad that refuses to start.
beforePack now reads each addon's PE machine against the target arch.

* refactor(windows-security): prune what the native ACL left dead (review #28135)

- Sync-spawn ratchet: hardenSecurePath and the sync-flag exemption it alone
  used are gone, and the advice and baseline header no longer say secure
  writers run icacls.
- The install-dir probe reads ACEs through parseSddlDacl, so an ACE it
  cannot parse fails the whole reading closed instead of being skipped; AC
  is a resolved alias there now.
- The packaging check reads the addon binary through node_modules, the copy
  that ships.
- No winCode-to-errno table: nothing reads .code off a failed secure write.
- The load memo is not mutated; secure-path keeps its own log-once flag.
- grantInstallDirPackageAcl is a plain function, and secure-file restricts
  a Windows directory and a POSIX path directly instead of through one
  two-platform helper.

* fix(windows-security): resolve LA in real-ACL tests; tear a file whose close fails

- The GitHub Windows runner is the built-in Administrator (RID 500), whose
  SID reads back as LA. Production already resolves it through
  localDomainSidOf; the win32 test helpers parsed without it. One shared
  readDaclOf resolves aliases for every real-ACL suite, and the verifier's
  unit test covers an LA-aliased directory and LA as a stranger.
- createFileWithDacl treats a failed CloseHandle like a failed write (lost
  data on a network volume) and deletes the torn file.
- Drop a duplicate test reset and a typo.

* fix(windows-security): load only from inside the app; read DACLs as structure (review #28135)

- Loader: orcad's staged binary first, then the workspace package only if
  its real path is inside the app (process.resourcesPath, or this
  checkout). A bare specifier otherwise walks every parent up to
  C:\node_modules, which any local user may create, and orcad holds
  credentials.
- The addon reads a DACL as { protected, aces: [{ type, flags, mask, sid }] }
  via GetAce, with a SID only for plain allow/deny ACEs and null for a NULL
  DACL. findSecureDaclViolation and the install-dir probe check that
  structure, so conditional, callback and object ACEs fail closed. The SDDL
  parser, its alias table, LA/localDomainSid resolution and getDaclSddl are
  gone; SDDL is only the write format.
- Install-dir tree pass: files flagless as before, but a directory only when
  its own DACL is protected (inheritably). Re-granting inheriting
  directories re-propagated each subtree (3.2 s for 1,093 directories). The
  root is no longer granted, or counted, twice. The two passes are plain
  functions behind a { root, tree } seam.
- One namespacing (path.win32.toNamespacedPath) at the addon boundary, also
  the per-path ordering key; the comment states the real sync-grant
  invariant.
- restrictWindowsDirectory(dir): Promise<boolean> replaces the callback
  lane; the reporter is guarded once, so the 'settle' stage is gone.
- Sync-spawn ratchet: the secure writers no longer spawn or block, so they
  leave the gate (109 -> 61 uses).
- Errors name the Win32 call and code only; a failed
  GetSecurityDescriptorControl fails the write instead of defaulting to
  unprotected.

* test(secure-file): assert the durable POSIX write's outcome, not the old chmod order

writeSecureFile now chmods the temp file to 0o600 before fsyncing it, so
the fsync also covers the mode change and the file is owner-writable when
opened. Assert what matters under umask 0o200: the write succeeds, the
temp file is fsynced read-only, and the published file is exactly 0o600.

* fix(windows-security): namespace paths with the host's toNamespacedPath

path.win32.toNamespacedPath rewrote POSIX temp paths (/tmp/x -> \tmp\x) in the
Linux runs of the Windows-logic unit tests, so the fake addon wrote to the wrong
place. The addon only runs on Windows, where the host function is the win32 one;
elsewhere it is the identity. The long-path assertion runs on Windows only.

* test(windows-security): assert the install-dir long-path prefix on Windows only

The prefix comes from the host's toNamespacedPath, which is the identity off
Windows; the Linux run of this suite expected the win32 escape.

* fix(windows-user-data-acl): grant the root even when its children cannot be listed (review #28135)

A readdir failure on userData aborted the whole grant, so the root grant
that could repair a DACL refusing the listing was never attempted. The
listing failure is now recorded, the root is still granted, and the
marker stays withheld so the next launch retries.

* test(windows-security): wait for relock propagation, accept Entra ID SIDs (review #28135)

- The large-relock test waited only for the parent to turn protected,
  which happens before propagation reaches the children, then read a child.
  It now waits on the parent and both ends of the child range.
- The token-user test rejected S-1-12-1 (Entra ID) accounts, failing the
  suite on Entra-joined dev machines.

Brennan Benson fa4ef2b961 ci: stop new main-process code from freezing Orca with synchronous launches (#27756)
* ci: ratchet synchronous child-process launches in main and shared code

The Electron main process freezes every window while a synchronous child
process runs, and on Windows each launch is slow because antivirus scans
it. Nothing stopped new synchronous launches from landing in main-process
code, and the spawn observer behind ORCA_MAIN_THREAD_DIAGNOSTICS only saw
async spawns, so the worst blocks were invisible to it.

Ratchet: check:main-sync-spawn-ratchet parses production src/main and
src/shared files (test-only paths excluded) and fails when a file not in
config/main-sync-spawn-baseline.txt reaches execFileSync, spawnSync or
execSync from child_process, runProcessSync from @orca/process-host, or
one of the synchronous secure-file writers (they run icacls on Windows).
Named, aliased, namespace, default, require() and import() forms count.
A baseline entry whose file no longer launches synchronously fails as
stale, so the list can only shrink. It runs in lint and in the PR
static-analysis job next to the process-host import check.

Observer: runProcessSync now reports to the spawn observer, timing the
whole call (that is how long the thread was stuck) and reporting from a
finally so failing, throwing and timed-out children are counted too.

Runtime behavior is unchanged except that the diagnostics observer now
sees synchronous launches; with no observer registered the sync path
pays one extra branch.

* ci: count sync launches per file and gate the repo's sync wrappers

The sync-spawn ratchet only tracked which files launched synchronously, so a
file already on the list (wsl.ts, win32-utils.ts, git-exec-file.ts) could add
more launches unnoticed, and new callers of the repo's own synchronous
wrappers passed CI.

The baseline now stores a per-file count of uses, in the same format as the
focus-read ratchet: a rise or a new file fails, a lower or zero count fails
until `pnpm check:main-sync-spawn-ratchet --prune` lowers it, and --prune
never raises an entry. Every value reference to a gated function counts
(call, hand-off, alias and its uses, re-export); imports alone count nothing.

Gated wrappers: gitExecFileSync (and the git/runner re-export),
restrictWindowsPathSync, hardenSecurePath when called with sync: true,
grantDirAcl, getWslHome, listWslDistros, wslUncDirectoryExists,
isWslAvailable (and the wsl.ts re-export), isPwshAvailable. Their 18
current caller files join the baseline.

Failure messages now give advice per family: the async process-host API for
child-process launches, the async twin for wrappers, and for the secure
writers a note that no async secure writer exists yet, so the sync one stays
and must never become a plain write (that drops the Windows ACL hardening).

Also refresh two stale blockMs descriptions and drop a no-op line from the
spawn-observer "stays silent" test.

* ci: count hardenSecurePath unless visibly async, and tighten ratchet tests

hardenSecurePath was counted only when `{ sync: true }` was written inline,
so moving the options into a variable or a spread dropped the count and the
check then asked for a prune. It now counts every use except a call with no
options or a spread-free object literal whose `sync` is absent or false.

Also: resolve backslash paths in the importing file as well as the
specifier; still visit heritage and instantiation expressions
(`extends mixin(fn)`, `fn<T>`); state the reference-only counting limit;
and point the secure-writer advice at raising this file's baseline count.

Tests cover the hardenSecurePath shapes, the alias chains that need the
fixpoint loop, and a prune that must not raise a grown row.

* test(ci): pin the main sync-spawn ratchet background step

* fix: count secure hardening calls with spread arguments
