Neil 4fc1855bda build: share one pnpm virtual store across worktrees (off in CI and on Windows) (#30254)
* build: share one pnpm virtual store across worktrees, off under CI

Each worktree carried a full node_modules; the global virtual store links
one slot per package version instead. pnpm keeps an explicit setting on
under CI, so a pnpmfile hook turns it off there: CI packages from,
caches and verifies a project-local node_modules.

* fix(build): keep shared electron and windows-process-tree dirs untouched under GVS

Every worktree runs Electron from the one shared electron package, so the
per-repo dist cache must not swap that dist and a foreign-arch install must
not land in it. The relay addon builder now repairs and compiles a private
copy instead of the shared windows-process-tree dir.

* fix(build): accept CLI runtime imports reached through an in-artifact store link

Under the global virtual store node_modules/<pkg> realpaths into a store
outside the repo. The check still rejects anything not reached through a
node_modules link inside the artifact, such as a stray ~/node_modules.

* docs: explain the global virtual store layout and the ~/node_modules hazard

* test: compare CLI closure paths with POSIX separators so the suite passes on Windows

* build: keep Windows on the normal pnpm layout unless ORCA_PNPM_GLOBAL_VIRTUAL_STORE=1

Store links are true symlinks on Windows, and installs without admin or
Developer Mode are unverified; CI still forces the normal layout first.

* fix(build): close the remaining shared-slot gaps under the global virtual store

- verify-skills-cli-runtime resolves each import from the importer's realpath,
  as Node does, so an artifact-local copy can't mask a ~/node_modules load.
- A concurrent sibling install of the shared Electron dist is kept, not swapped out.
- rebuild:node goes through ensure-native-runtime, which builds a shared
  node-pty beside the slot instead of node-gyp cleaning its build/ dir.

* fix(build): keep pnpm rebuild:node a forced rebuild

It replaced pnpm rebuild node-pty, which always rebuilt; without --force it
only rebuilt a node-pty that failed to load.

* docs: note that the store switches must stay set, since pnpm run relinks

* build: move the pnpmfile under config/ to keep the repo root allowlisted

pnpm-workspace.yaml points pnpm at it; the lockfile checksum is unchanged
because the content is.

* fix(build): enable the global virtual store from the pnpmfile, not the workspace file

pnpm exec derives NODE_PATH from the file setting, so even with the store
forced off under CI every child process got the root node_modules on its
NODE_PATH; a Windows rebuild fixture then resolved the real
@orca/windows-registry it deliberately omits. The hook now sets the store
both ways, and ORCA_PNPM_GLOBAL_VIRTUAL_STORE=0/1 is the one switch.

* test(pty): keep F3's concurrent spawns on the node-pty mock

Two concurrent first import('node-pty') calls race vitest's mock registry
and the loser loads the real addon under the mocked linux platform. It
passed only where a platform-agnostic build/Release happened to exist,
so it failed on every shared-store worktree.

* ci: fail PRs whose packages need a dependency they never declared

A new dependency_isolation job installs with the global virtual store
forced on (ORCA_PNPM_FORCE_GLOBAL_VIRTUAL_STORE_IN_CI), HOME and the store
in an empty temp dir, then runs pnpm tc and the undeclared-dependency test.
Postinstall now warns when a node_modules above the shared store, such as
~/node_modules, would mask the same class of bug locally.

* ci: set the isolation job's HOME and store through GITHUB_ENV

Job-level env cannot read the runner context, which made pr.yml invalid.

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 c9097ac991 test: run a structured chat against the packaged headless server (#26527)
* fix: preserve module URLs in the headless server bundle

* test: exercise structured chat on the packaged Node server

* test(orcad): run the packaged chat check from the desktop's server template

The chat check loaded the server bundle directly, so a desktop build missing its
server template still passed. Materialize the slot from the built template the way
the desktop does, and replace the fixed streaming pause with a test-owned
acknowledgement so the partial-reply assertion can't race.

* Connect the packaged chat test through a paired connection

Main now sends remote runtime requests over a paired connection rather than a
pairing offer, so the test converts the server's offer once when it is ready.

Neil 1912c90141 Extract subprocess handling into @orca/process-host (#26963)
Extract subprocess execution and process contracts into @orca/process-host with explicit public entry points, independent checks, and one Node 18 compatible CommonJS runtime. Migrate application consumers and integrate package builds, dependency selection, import enforcement, and runtime resource staging.

Preserve daemon startup ownership and profile isolation, and qualify development rebuild recovery and concurrent output publication. Remove unnecessary aliases, test forwarding exports, and a duplicate output scan.

Validation: full typechecks, changed-code quality, package and artifact checks, native Windows builds/types plus 306 runtime tests, and independent native reviews.

Matched full E2E controls on original main and unchanged reviewed head both pass all 17 applicable tests (nine skips). Earlier intermittent E2E failures are documented in the PR; no assertions were weakened. The final combined-tree audit preserves both branches with no import-boundary violations.

OrcaWinandm4air 6593d7d194 feat(orcad): run orcad on the pinned Node instead of Bun (#24110)
* ci(daemon): gate PRs on daemon protocol crossing from the newest release

Lands daemon-protocol-facts.mjs from the Windows update diagnostic branch with a
stricter parser, and adds check-daemon-protocol-crossing.mjs (rule R1): the working
tree must attach the newest release tag's daemon. Rollback crossing is reported only.
Runs in the cross-version-wire job, which already has full tags; tag selection moves
to config/scripts/stable-release-tags.mjs so both use one rule.

* feat(persistence): run profile backups in the worker whenever its entry is bundled

* refactor(orcad): make profile and native preflight runtime-neutral

The profile preflight parser now takes the expected runtime identity from the
caller (shipped callers pass the pinned Bun identity), and the native
preflight is renamed to orcad-runtime-native-preflight with neutral wording.

* feat(runtime): pin the Node 24.21.0 server runtime with an offline CI check

Add src/shared/node-runtime-pin.ts (NODE_RUNTIME_PIN, SERVER_TARGETS,
NODE_RUNTIME_ASSETS for all 8 server targets plus the headers tarball),
generated by config/scripts/update-node-runtime-pin.mjs from the nodejs.org
and unofficial-builds SHASUMS. check-node-runtime-pin.mjs verifies, with no
network, that the pin tracks the locked Electron, matches engines.node's
major, and covers exactly SERVER_TARGETS; it runs in the static analysis job.

ORCAD_BUN_TARGETS consumers now read SERVER_TARGETS so there is one target
list; orcad's Bun runtime and build output are unchanged.

* test(persistence): skip plain-Node backup selection tests in the Bun profile suite

* fix(runtime): reject a pinned archive that belongs to another target

* ci(daemon): fail PRs that swap a runtime launcher and bump the daemon protocol

D7.1 R3: hosting orcad or the daemon on another runtime is not a protocol change,
so one PR must not do both. The launcher file list lives in the check script; the
allow-runtime-launcher-protocol-bump label overrides it.

* feat(orcad): select pinned-Node slots by a .runtime-node marker

D7.1 R5: a Node slot names its shared runtimes/node-<sha256>/node through
.runtime-node instead of .build-target, so Bun-era clients read it as a legacy
slot rather than exiting 78 on a missing bun-runtime. Nothing builds the marker yet.

* fix(runtime): load the Node pin without the typeless-module warning

check-node-runtime-pin.mjs now requires the pin and takes nodeDistArchiveName from
its own module, so it no longer loads the update script's build graph.

* fix(orcad): resolve Node slots to the design's runtimes/node-<sha>/bin/node layout

* feat(orcad): 8-slot node-pty prebuilds against the pinned Node headers at N-API 8

- build-orcad-prebuilds.mjs adds win32-x64/arm64 (conpty.node, the vendored
  conpty.dll/OpenConsole.exe, upstream's N-API conpty_console_list.node), compiles
  in a scratch copy against the hash-verified pinned headers (node.lib pinned per
  Windows arch) with NAPI_VERSION=8, rejects post-8 node_api_* imports, and writes
  a schema 2 manifest with per-file sha256, N-API level and the glibc need.
- --require-slots [slots] verifies files against hashes; --smoke loads the slot
  under the pinned Node and spawns a PTY; --print-slot names the host slot.
- The slot installer gates on N-API, libc, arch, glibc and file hashes instead of
  the exact NODE_MODULE_VERSION, and installs nested files (conpty/).
- bun-profile-tests.yml builds, verifies and smokes each runner's slot.

* fix(orcad): scope node-pty's glibc .symver pins to glibc on musl prebuild slots

musl's unversioned libc cannot satisfy openpty@GLIBC_* references at link
time, so the Alpine slot compile would fail. Pin the staged pty.cc guard to
__GLIBC__ and assert both musl transforms against the installed patch.

* feat(orcad): run orcad on the pinned Node instead of Bun

A packaged orcad slot now references the pinned Node 24.21.0 by its
executableSha256 (`.runtime-node`, `.server-target`) instead of carrying
bun-runtime, and ships node-pty from the slot's prebuild, only its own
ripgrep, and no Windows Bun PTY gate. The runtime lives beside the slots
at runtimes/node-<sha>/bin/node (node.exe on Windows, upstream name).

- build:orcad (build-orcad-node.mjs) builds the host slot's prebuild when
  missing and places the pinned runtime; the template is schema 3 with
  per-target files.
- handoffToBundledOrcad() resolves the slot's runtime reference and checks
  process.versions.node against the pin; a host Node >= 18 still hands off.
  Startup preflight keys on running as that runtime; callers expect 'node'.
- orcad and its daemon use node-pty (ConPTY + windows-pty-job on Windows);
  the Bun PTY sources, gate entry and canUseBunPty branches are removed.
- SSH deploy uploads the official archive once per pin, extracts and
  hash-checks it on the host, and self-tests it before publishing. Bun
  slots stay launchable for rollback; Node slots never use host Node.
- The runtime materializer is generic over pinned assets; the Bun wrapper
  remains only for the OpenCode vault reader (design Phase 2).
- Cross-runtime test: a profile DB written by Bun 1.4.2 (WAL left by
  SIGKILL) opens and backs up under the pinned Node, and the reverse.

No daemon PROTOCOL_VERSION change (design D7.1 R3).

* docs(ci): name the headless lanes after the pinned Node, drop Bun shard timings

Design D10: ci-demand-rollout.md and ci-runner-efficiency.md follow the
bun-profile-tests.yml -> node-server-tests.yml rename; shard timings drop the
deleted Bun PTY tests and follow the renamed ones.

* chore(ci): count the runtime archive download as a runtime launcher path

* fix(orcad): pin the macOS C++ standard for node-pty prebuilds

The official Node headers' config.gypi sets clang: 0, so common.gypi skips its
gnu++20 xcode_settings and Apple clang 15 (macos-14 runners) compiles
node-addon-api as C++98.

* fix(orcad): resolve the preflight's slot through realpath, as the handoff does

A symlinked orcad.js handed off to its real slot's pinned Node, but the
startup and profile preflights read the symlink's directory, found no
runtime marker there, and silently skipped the readiness check.

* refactor(ssh): drop materializeCachedNodeRuntime, which nothing calls

Deploys upload the verified official archive (design D5); no client path
needs an extracted Node executable cached by digest.

* test(orcad): gate the Bun-to-Node upgrade and Node-to-Bun rollback with live terminals

Design D7.1 R1/R3/R4 and D7.2. The last Bun orcad and this checkout's Node
slot are installed side by side under ~/.orca-remote, launched and stopped
with the client's own deploy commands, and share one data root. Each
direction proves the incoming orcad adopts the outgoing runtime's daemon
(same PID, same shell, output continues), opens its profile database and
backs it up with its own shipped worker, and that GC keeps the slot the
live daemon was forked from.

The node-server Linux lanes provide Bun 1.4.2 and build that Bun orcad
from main, and run with --cross-runtime. --artifact and --cross-runtime
now make their tests fail on a missing input instead of skipping.

* ci(node-server): pin node:24.21.0-alpine by its multi-arch index digest

* test(ssh): name the runtime archive fixture after its role

* test(node-server): load node-pty from the packaged slot in artifact runs

The node-server lane installs dependencies without building node-pty, and
Linux has no upstream prebuild, so the real-PTY failed-I/O teardown test
(picked up by the pty-subprocess selector) could not load pty.node. In
--artifact runs, alias node-pty to out/orcad's shipped slot so the test
exercises the addon orcad actually runs under the pinned Node.

* fix(orcad): let the Windows profile preflight exit after its PTY probe

On Windows, node-pty keeps the conout worker thread and pseudoconsole alive
until kill(), even after the shell exits. The PTY health probe never killed a
cleanly exited probe, so the packaged preflight printed its readiness line
and then hung until the build's 30s timeout, reported with an empty stderr.

- The probe kills its PTY on Windows after exit and uses the bundled ConPTY
  the daemon spawns with.
- The preflight exits once stdout is flushed; its owner reads to EOF.
- Preflight failures now report code, signal, timeout, stdout and stderr.

* test(node-server): load the slot's node-pty in the real-PTY test, not by alias

A vite alias redirected only ESM imports of node-pty; windows-pty-job and
local-pty-utils resolve it through require, so Windows loaded two conpty.node
copies and the Git Bash job-membership proof read an empty job. The failed-I/O
teardown test now loads node-pty through a fixture that picks the packaged slot
in artifact lanes.

The pty-subprocess selector was a prefix that also pulled in its POSIX-host
sibling unit tests, which pr.yml runs and which were never qualified on
Windows. Select the directory plus the two sibling files that belong here.
