feat(codex): real-home routing + self-contained multi-account homes (#9501)
* feat(codex): backfill managed-home sessions into the real Codex home once per host

Orca-launched Codex sessions currently land only in the Orca-managed
runtime home, so the user's own `codex resume` picker and app history
never see them (#4444, #8612). Backfill the managed sessions tree into
the real ~/.codex/sessions/YYYY/MM/DD layout once per host:

- hardlink first (one physical rollout log), copy as the cross-volume
  fallback; existing target files are always skipped, nothing in either
  home is deleted or moved
- idempotent; per-file failures leave the completion marker unset so the
  next startup retries cheaply
- JSONL audit log of every link/copy/failure under
  <userData>/codex-session-backfill/
- honors the custom Codex session source home override, mirroring the
  existing system->managed bridge

WSL managed homes are distro-local and need an in-distro variant; that
is a follow-up.

* feat(codex): flag-gated system-default real-home routing scaffolding

Staged internal flag (default OFF, no settings UI): route the SYSTEM-DEFAULT
Codex account at the user's real ~/.codex instead of Orca's managed runtime
home. Flag OFF is byte-identical to today; managed (multi-account) selections
are unchanged in either state.

Routing (flag ON + host system default = no managed account):
- CodexRuntimeHomeService.prepareForCodexLaunch / prepareForRateLimitFetch
  return null so the PTY/env layer injects no managed CODEX_HOME and the
  rate-limit fetcher + auth-presence gate fall back to ~/.codex (the background
  poller stops spawning Codex against the managed home — the #5370 auth war).
- buildPtyHostEnv strips only a nested-Orca-inherited Orca-owned override
  (CODEX_HOME matching the private ORCA_CODEX_HOME marker), preserving a
  user-set CODEX_HOME. Shell-ready re-exports already no-op without the marker.
- The headless commit-message Codex path strips the same inherited override.

Hook install for the real-home lane (append-last into ~/.codex/hooks.json,
trust via the app-server client) lands with the trust plumbing; the managed
hook install is skipped for this lane meanwhile.

Credit @jellychoco (#8606) for the native-home routing direction.

Depends on the codex trust-rpc-grant plumbing for the real-home hook installer.

* fix(codex): strip the daemon-inherited Orca CODEX_HOME override for real-home routing

The daemon spawns PTYs from its own inherited environment and honors only
spawnOptions.envToDelete, so mutating the sparse env object was not enough to
strip an Orca-owned CODEX_HOME the daemon already carries. Add the strip to
envToDelete for both daemon host-spawn paths, preserving a user-set CODEX_HOME.

Verified live via CDP against a sandboxed dev instance (flag ON): an
Orca-spawned pane reports empty CODEX_HOME/ORCA_CODEX_HOME, so Codex resolves
its own ~/.codex. Adds daemon-path unit coverage (strip Orca-owned, preserve
user-owned, no-op when flag OFF).

* fix(codex): harden one-time session backfill

* test(codex): cover staged cross-volume install

* feat(codex): app-server trust-grant client, capability cache, and grant ledger

Short-lived codex app-server JSON-RPC client (hooks/list + config/batchWrite,
the same pair the Codex TUI 'Trust all' flow calls), run in a bundled
ELECTRON_RUN_AS_NODE entry so synchronous launch prep can block on it with a
hard deadline and guaranteed child reap. Capability cache modeled on
GitCapabilityCache, scoped per execution host (native vs each WSL distro),
with a narrow unknown-method/missing-subcommand unsupported predicate. The
grant ledger records verified grants so steady-state launches skip the RPC.

* fix(codex): grant managed hook trust via codex app-server RPCs in install/refresh

Host and WSL installs now grant trust for Orca's managed status hooks through
codex's own hooks/list -> config/batchWrite -> re-list verify, scoped to
exactly the managed entries; the previous computeTrustedHash lane is the
unchanged fallback for incapable/erroring CLIs. getStatus and the removal
paths recognize ledger-recorded codex hashes so drift between codex's real
algorithm and the replica no longer misreports or strands trust. SSH remote
install is untouched by design.

* test(codex): cover app-server trust grant client, cache, ledger, and lanes

* test(codex): cover commit-message real-home override strip/preserve

Adds the two cases for the headless commit-message Codex env under real-home
routing: a nested-Orca-inherited Orca-owned CODEX_HOME is stripped, and a
user-owned CODEX_HOME is preserved.

* test(codex): WSL grant-lane coverage — in-distro invocation and fallback parity

* feat(codex): real-home hook installer trusted via the codex app-server grant client

With the real-home flag ON and the system-default selection, install Orca's
status hook into the user's real ~/.codex before any pane spawns:

- entry APPENDED LAST per managed event: codex hook trust keys are positional
  (source:event:group:handler), so appending keeps every user entry's position
  and trust record intact; user entries and unknown top-level hooks.json fields
  are preserved verbatim
- trust is granted exclusively through the codex app-server client
  (hooks/list + config/batchWrite, verified by re-list); Orca never writes
  [hooks.state] into the user's real config.toml itself
- if the grant lane is unavailable (old binary, unsupported RPC, verify
  failure), the appended entry is rolled back byte-exactly and the host keeps
  the managed-home lane end to end (PTY env, rate limits, commit messages)
  via a lane gate on the runtime-home service
- one-time pristine backup of the user's hooks.json under Orca's userData;
  a rolling .bak sits next to the file (existing atomic writer)
- hook opt-out sweeps Orca entries from the real home and drops Orca-owned
  trust records; flag-off downgrade re-arms the existing legacy system-home
  sweep, which removes the entry and its trust keys cleanly
- the legacy system-home sweep is suppressed only while the real-home lane
  owns ~/.codex/hooks.json, so managed installs cannot delete the entry

* fix(codex): resolve the trust-grant entry without requiring electron

The grant bridge is reachable from plain-Node CLI entries, where the
plain-node entry guard rejects any chunk containing require("electron").
Resolve the bundled session entry from __dirname (root chunk and chunks/
layouts) with an app.asar -> app.asar.unpacked rewrite for packaged runs,
instead of electron's app path APIs.

* fix(codex): keep session backfill off main thread

Use asynchronous, sequential filesystem operations for the one-time rollout backfill, and avoid repeated target-directory probes. Treat inaccessible managed session roots as retryable failures instead of writing a false completion marker.

* fix(codex): harden app-server trust grant fallback

* fix(codex): install cross-volume session backfill copies atomically

On a real Codex home whose filesystem supports no hardlinks (exFAT/FAT,
some network mounts), the staged cross-volume copy was installed with a
non-atomic copyFile(..., COPYFILE_EXCL) straight into the final
rollout-*.jsonl name. An install interrupted mid-copy (app quit, crash,
ENOSPC during the deferred run) could strand a truncated rollout that the
next run then skips as already-present, defeating the staging design's own
guarantee that a failed copy never leaves a partial session behind.

Install the fully-staged copy with an atomic rename instead, guarded by an
existence re-check so it keeps the never-overwrite contract (and the rename
source is the same immutable managed rollout, so any clobber would be
byte-identical). Cover the no-hardlink-support target and an interrupted
install that must leave no partial in the user's sessions tree.

* fix(codex): resolve grant entry from __dirname so plain-node CLI entries stay electron-free

The build guard rejects any electron require reachable from plain-node
entries; the bridge now maps app.asar to app.asar.unpacked by string
replacement instead of consulting electron app paths. CLI typecheck project
lists the new trust-grant module graph.

* fix(codex): harden trust grant reconciliation

* fix(codex): restore trust config permissions on rollback

* fix(codex): harden real-home routing cleanup and retries

* fix(codex): preserve unicode trust RPC responses

* fix(codex): preserve remote env and complete real-home cleanup

* fix(codex): preserve real-home lane invariants

* test(terminal): isolate replacement idle reset assertion

* fix(codex): preserve real-home dotfile links

* fix(codex): preserve verified trust grants across launch prep

* fix(codex): preserve dangling config symlinks on rollback

* fix(codex): don't revoke a just-granted WSL home on a false 'missing' probe

The async wsl.exe canonical-path settlement could report the runtime home
'missing' immediately after a verified RPC grant (a false negative — codex
had just written and re-listed trust there), which drove the reconciliation
'remove' branch to delete all six granted [hooks.state] tables, leaving a bare
[hooks.state] the launching pane read as 'hooks need review'. A 'missing'
settlement now revokes only when no successful install ran this generation; a
genuinely moved home still resolves to a different path and reinstalls.

* test(codex): model codex config/batchWrite faithfully on Windows

The grant-lane stub simulated codex by calling Orca's upsertHookTrustEntries,
which writes both separator variants for a Windows key (a fallback-lane compat
shim real codex never does) — fabricating duplicate tables and whitespace the
RPC path never produces, so the byte-stable and no-duplicate assertions failed
on win32. Replace it with a single-variant, blank-line-separated writer that
matches the real 0.144.x binary's output.

* feat(codex): collapse duplicate session listings across Codex roots

Backfilled/bridged rollouts are hardlinked into both the real ~/.codex and
Orca's managed runtime home, so AI Vault listed each session once per root
(#7521). Dedup candidates by rollout file name pre-parse and parsed sessions
by session id post-parse, keeping the canonical root: host real home first
(unprefixed resume), then the managed runtime home, then other homes. Applies
to local, WSL, and SSH-remote scans.

* feat(codex): background sqlite index heal for backfilled sessions

Codex's own state-DB metadata backfill is one-shot, so rollouts hardlinked in
by Orca's session backfill never become visible to Codex's DB-driven surfaces.
Extract the app-server stdio JSONL transport into codex-app-server-session
(shared with the trust-grant client) and add a bounded, resumable background
pass that drives Codex's lazy indexing via thread/read per backfilled session:
recent-first, batched onto one short-lived server per batch with small
concurrency, ledger + marker so steady-state startups are a no-op, stop-aware
on quit, and capability-aware on CLIs without the app-server surface.

* fix(codex): preserve session identity during dedup heal

* fix(codex): preserve user trust during real-home cleanup

* fix(codex): harden real-home heal boundaries

* fix(codex): fail closed on unsafe backfill install

* fix: harden real-home hook cleanup

* fix(ai-vault): preserve execution boundaries and reap children

* fix(codex): narrow app-server unsupported detection

* fix(codex): bound user hook trust rebase retries per host

The rebase lane ran a codex app-server session on every launch prep while a
host was stuck (CLI without app-server support, or keys hooks/list cannot
match). Gate the transaction on the shared capability cache and add the same
5-minute transient cooldown the grant lane uses, so sweep and legacy-cleanup
retries cost plain fs reads instead of a codex session per pane spawn.

* fix(codex): enforce real-home resume and heal boundaries

* fix(codex): establish real-home lane before cleanup

* fix(codex): stop index heal before delayed spawn

* fix(codex): protect symlinked rolling backups

* fix(ai-vault): preserve resume env deletion through drag

* fix(codex): strip inherited Codex homes on mobile real-home resume

The mobile resume surface types a bare real-home codex resume into a
freshly created pane, but never asked for CODEX_HOME/ORCA_CODEX_HOME
deletion at pane spawn, so an agentDefaultEnv-pinned or daemon-inherited
Codex home rerouted the resume away from the user's real ~/.codex while
the same session resumed correctly on desktop. Share the deletion helper
from the AI Vault resume builders and forward it through the mobile
launch and session.tabs.createTerminal call.

* fix(codex): gate session migration on real-home lane

* fix(codex): stop session backfill after opt-out

* fix(codex): keep session heal failures retryable

* fix(codex): keep session migration state recoverable

* fix(codex): retry republished missing session heals

* fix(codex): align hook trust source paths

* fix(codex): harden trust grant lifecycle

* fix(codex): restore envToDelete on client invocation type after base reconcile

* test(codex): type child.stdout as PassThrough for oversized-output write

* Assemble RC: reconcile app-server transport API across PRs

Unify on the object RPC surface from the index-heal transport (#8921) while
preserving the default-home env strip (#8828) and the narrowed missing-app-server
capability signal (#8847): adapt the user-hook-trust-rebase consumer + tests,
port envToDelete stripping into the shared session, and route stderr
classification through the canonical capability-signal module.

* RC: enable system-default real-home routing by default (flag ON)

Flip codexSystemDefaultRealHomeEnabled to default ON for this RC's staged
rollout (a user can still opt out by setting it false, which stays byte-identical
to managed-home behavior). This is the only intended behavior difference between
the RC branch and the individual PRs. Updates the two tests that assumed the
prior OFF default.

* fix(codex): snapshot hooks.json bytes+parse in one read to close real-home clobber race

The install/sweep/legacy-cleanup paths parsed hooks.json, then did a separate
later read to capture the previous bytes for the pre-write generation guard.
A concurrent save (second Orca instance or the user editing the file) could
land between the parse and that second read and be silently overwritten.
readHooksJsonWithRaw returns the raw bytes and parse from a single read so the
guard compares against exactly what it parsed. Adds a regression test that
mutates hooks.json mid-RPC and asserts the sweep aborts without clobbering.

* fix(codex): sanitize managed account config trust

* fix(codex): guard OAuth add for custom providers

* fix(codex): persist outgoing managed tokens before real-home lane takeover (PR-C)

prepareForCodexLaunch returns null early for the real-home / system-default
lane before syncForCurrentSelection runs. If a managed account is still
recorded as synced when the selection has dropped to the system default
(nulled without a sync pass, or auto-deselect on missing managed auth), a
Codex-refreshed token stranded in the shared runtime home is never persisted
to its canonical per-account home -> token loss.

Read the outgoing managed account's refreshed token back before the real home
takes over. The real-home lane implies host === null, so running the
managed->system-default transition restores only Orca's runtime mirror from
~/.codex and never writes the real ~/.codex. It is a no-op once the selection
has already been reconciled, so the normal select path does not double-write.

* fix(codex): preserve refreshes across all default transitions

* feat(codex): show system-default/real-home account identity in switcher (PR-B)

The account switcher modeled the system-default Codex account as
activeAccountId:null with no identity fields, so the null row rendered
blank ("System default" / generic subtitle) even though its effective
login is whatever ~/.codex/auth.json currently is.

Add a CodexSystemDefaultIdentity descriptor {hasAuth, authKind, email,
providerAccountId, workspaceLabel} to CodexRateLimitAccountsState,
resolved live and READ-ONLY from ~/.codex by the accounts service and
returned from listAccounts()/getSnapshot(). The settings switcher now
renders the null (system-default) row as that real identity: the OAuth
email when signed in, "Custom provider — no usage tracked." for
env-key/custom-provider logins (auth.json with OPENAI_API_KEY, or an
OPENAI_API_KEY env with no auth.json), and the generic fallback when
signed out. Identity is host-scoped (per-distro WSL keeps the generic
label). Orca never writes ~/.codex; managed-account switches only touch
Orca-owned homes, so the system-default identity stays a stable,
displayed source of truth. Usage already routes to the real home via
getSystemCodexHomePath, so the switcher now attributes it to a real face.

Tests (sandboxed temp homes only): OAuth email/provider resolution,
api-key auth.json and env-key (no auth.json) as custom-provider,
signed-out, and select/deselect of a managed account never mutating
~/.codex/auth.json.

* fix(codex): parse multiline provider pins in OAuth guard

* fix(codex): harden managed trust sanitization

* fix(codex): harden system-default identity rendering

* feat(codex): give each managed account a self-contained CODEX_HOME; retire shared mirror (PR-E)

With the real-home flag ON, a host managed account now launches directly
against its own codex-accounts/<id>/home instead of the shared runtime
mirror + auth.json hot-swap:

- codex-home-paths: syncSystemCodexResourcesIntoManagedHome links system
  resources into any managed home (ownership-marker discipline; never
  symlinks into / mutates ~/.codex).
- runtime-home-service: prepareForCodexLaunch / prepareForRateLimitFetch /
  syncForCurrentSelection route the per-account home directly and skip the
  shared-home hot-swap + token read-back; each home keeps its own auth in
  place (fixes GAP-5 concurrent auth race). Session discovery scans every
  per-account home.
- hook-service / hook-trust-promotion: install/getStatus/refresh accept a
  runtimeHomePath so hooks + RPC-granted trust land in the per-account home.
- service: config mirror into a self-contained home uses the trust-
  preserving merge so granted hook/project trust survives account switches.
- codex-session-root-dedup: rank codex-accounts/<id>/home as canonical
  managed alongside the shared runtime home.

Flag-OFF and the system-default real-home (null) lane are unchanged; the
nested-Orca CODEX_HOME===ORCA_CODEX_HOME daemon strip (#5370) is preserved.
Sandboxed tests only; ~/.codex is never mutated.

* fix(codex): validate per-account home ownership

* fix(codex): keep managed rollouts discoverable across real-home opt-out

WI-4 lossless migration/rollback validation for pre-E shared-mirror managed
accounts. Session discovery gated the per-account home scan on the real-home
flag, so opting back out (flag OFF) hid every rollout an account accumulated
while the flag was ON — the data stayed on disk but vanished from the AI Vault
until the flag flipped back on.

Scan a managed host home whenever it holds a sessions/ tree, independent of the
flag; a never-enabled install keeps its homes credential-only so opt-out stays
byte-identical to today. Forward migration was already lossless (the shared
mirror is always scanned) and the opt-out credential read-back already refuses
to overwrite a fresher per-account token; add tests locking all three
invariants. Sandboxed tests only; ~/.codex is never touched.

* fix(codex): migrate stranded shared auth on E takeover

* test(e2e): isolate Electron from developer Codex home

* test(codex): add real-account validation harness

* fix(codex): finish C and E matcher composition

* fix(codex): bound validation harness shutdown

* test(codex): isolate hook lifecycle user data

* test(codex): cover realistic account-home migration

* fix(codex): keep standalone home tripwire active

* test(codex): fingerprint system auth in validation reports

* fix(codex): bind managed homes to account ownership

* fix(codex): normalize Windows trust source identity

* fix(codex): make Windows trust upgrade transactional

* test(codex): use TypeScript pipeline for validation scripts

* test(codex): run validation modules through native node

* test(codex): allow slow Windows tripwire startup

* fix(codex): survive lingering Windows codex login processes in add-account

On Windows, codex login can keep running (with descendants) after it has
written auth.json, holding OS handles on the per-account managed home
(log/codex-login.log). That made doAddAccount's post-login cleanup fail
with ENOTEMPTY (rmSync) and left an orphaned codex-accounts/<id>/home.

- runCodexLogin now watches for auth.json on Windows and force-kills the
  login process tree (taskkill /t) if it lingers past a short grace
  period; the forced exit is treated as a successful login. The 120s
  timeout path also kills the whole tree instead of only the direct
  child. macOS/Linux behavior is unchanged.
- safeRemoveManagedHome now removes homes with rmSync maxRetries /
  retryDelay (mirroring the local-worktree-filesystem Windows policy)
  and no longer lets a cleanup failure mask the original add error.
- run-codex-real-account-validation.mjs accepts --temp-parent /
  ORCA_CODEX_VALIDATION_TEMP_PARENT so the disposable root can live
  outside %USERPROFILE% on Windows, and fails with an actionable message
  before creating anything when the temp parent is inside the primary
  home. The real-home guard is unchanged.

* fix(codex): preserve managed-account MCP .credentials.json on per-account-home migration (#8440)

Codex file-mode MCP OAuth tokens live in $CODEX_HOME/.credentials.json,
keyed by MCP server URL with no account identity of their own. The legacy
shared-mirror -> per-account-home migration only carried auth.json, so an
existing managed account with authed MCP servers had its tokens stranded on
upgrade and silently needed re-auth.

Carry the shared mirror's .credentials.json into the same identity-proven
per-account home alongside auth.json: only into the single uniquely-matched
active account (no cross-account leak), only when the destination has none yet
(never clobber a newer file the account authed in its own home), atomic 0600,
absent-source no-op. New MCP auth already lands in the per-account home since
that home is CODEX_HOME.

* fix(codex): preserve Windows reauthentication login flow

* test(codex): build real-account validation harness cross-platform on Windows

The harness built its app with execFileSync('npx', ['electron-vite', ...]),
but npx resolves to a .cmd shim on Windows that execFileSync cannot launch
(ENOENT), so the harness could not build its own app there and required
--skip-build with a prebuilt out/main/index.js.

Extract resolveElectronViteBuildCommand(repoRoot): it runs the repository-local
electron-vite JS entry (node_modules/electron-vite/bin/electron-vite.js) with
the current Node binary (process.execPath), which resolves identically on
macOS, Linux, and Windows with no shell. It throws a clear error if the local
entry is missing (install deps or pass --skip-build). --skip-build behavior is
unchanged.

Add regression coverage asserting the build command uses process.execPath and
the repo-local JS entry (not npx), and that a missing entry fails clearly.

* fix(codex): version the MCP creds migration independently of the auth marker

The auth carry and the MCP .credentials.json carry (#8440) shared one
existence-only v1 marker, so any build that stamped the auth-only marker
first would strand the MCP store forever. The MCP carry now concludes via
its own per-account-mcp-creds-migration-v1.json marker and runs even when
the auth marker is already present; ordering is code-enforced instead of
landing-discipline-enforced.

Also isolate per-account read failures: one stale or deleted account home
no longer aborts the whole migration. The broken account stays in the
unique-identity ambiguity gate via its stored fields but is never read or
written, so the active account still migrates.

* fix(codex): fail corrupt managed auth.json without echoing credential bytes

A raw JSON.parse SyntaxError from loadOAuthCredentials could carry auth
file fragments into logs and the add/reauth error surface. Throw a
sanitized error instead; filesystem errors still propagate unchanged.

* fix(mobile): give the pairing runtime a disposable home for the E2E boot guard

The main-process guard now refuses to start with ORCA_E2E_USER_DATA_DIR
set but the real user home, and this was the one caller not updated —
the temporary pairing runtime crashed before emitting its pairing URL.

* test(codex): canonicalize harness containment guards and retry cleanup

Resolve symlinks before the disposable-root containment checks so a
symlinked temp parent cannot smuggle the throwaway home inside the
primary home, and give the final cleanup rm Windows retry/force so a
briefly lingering codex handle cannot strand the credential-bearing
root.

* test(codex): add lane-aware containment mode to the real-account harness

The Windows gate-D run proved strict zero-event whole-profile containment
is structurally unreachable with the real-home flag ON: system-default
spawn sites deliberately delete CODEX_HOME so native codex resolves the
real ~/.codex, and on Windows the binary ignores the USERPROFILE sandbox.
Its own volatile runtime churn (root sqlite/WAL/SHM, tmp/, log/) is the
shipped Phase-1 design, not a candidate defect.

--lane-aware-containment records those designed events without aborting
while every other real-home write — auth.json, config.toml,
.credentials.json, hooks.json, sessions/, anything unknown — remains a
hard violation and still aborts the run. Default behavior is unchanged
(strict); the absolute zero-event claim stays carried by macOS runs,
where HOME does sandbox native codex.

* test(codex): allow the real-account harness to pin the real-home flag off

--system-default-real-home off seeds and env-pins the flag OFF so every
codex spawn gets an explicit managed CODEX_HOME and native codex never
resolves the OS profile. This is the only Windows configuration where the
strict zero-event whole-profile tripwire is reachable, and it matches the
stable-rollout default; flag-ON runs keep lane-aware classification.

* test(codex): correct the flag-off harness comment to kill-switch rationale

The rollout ships all codex-home changes at once (no phased rollout), so
flag OFF is the emergency kill-switch lane, not the stable default.

* test(e2e): canonicalize the isolated E2E home path

The disposable HOME lives under os.tmpdir(), whose spelling is an alias
on CI (macOS /var symlink, Windows 8.3 RUNNER~1). Git canonicalizes
worktree paths, so worktrees created under the aliased home never
matched the app's listing — golden core flows and the packaged
crash-survival harness failed with 'worktree created but not found in
listing'. Resolve the home to its canonical spelling at creation in
both the e2e helper and the packaged-app driver.

* fix(codex): address CodeRabbit review on the landing PR

- carry envToDelete through the mobile agent-resume startup plan so a
  real-home Codex resume cannot inherit an ambient CODEX_HOME
- strip Orca-owned Codex overrides in the commit-message WSL fallback,
  matching the host fallback
- strip ELECTRON_RUN_AS_NODE in the computer-e2e driver like every other
  home-isolation caller
- drop the unused hooksEnabled parameter from isRealHomeCodexHookLaneUsable

* feat(codex): ship real-home routing unconditionally, remove the rollout flag

The codexSystemDefaultRealHomeEnabled setting is gone from types and
constants and the helper no longer consults settings — the system-default
real-home lane and per-account homes ship for everyone in one release.
This also un-strands profiles that rc-era builds stamped with false (the
setting had no UI, so every stored false was a seeded artifact that would
have silently kept those users on the legacy mirror forever).

The ORCA_CODEX_SYSTEM_DEFAULT_REAL_HOME env override survives strictly as
a test-rig control: the containment harness pins the legacy lane for
strict zero-event Windows runs, e2e home isolation pins lanes inside
disposable homes, and the legacy-lane test suites now route their
per-test lane selection through it.

Suppress Git Credential Manager OAuth popup loop in Orca-run git — clone, terminals/agents, setup hooks (fixes #7652) (#7986)
* Suppress Git Credential Manager OAuth popup on git clone (fixes #7652)

Orca's git runner disables the interactive credential prompt on every git
call that goes through gitExecFileAsync/gitStreamStdout, but the two raw
'git clone' spawns (desktop repos:clone and the runtime clone path) passed
no env, so they inherited process.env with no guard. On Windows a clone
that needs GitHub auth then makes Git Credential Manager pop its
'Connect to GitHub' OAuth window, and in a network-restricted intranet the
browser/device flow never completes while git's credential retry re-pops it.

Apply nonInteractiveGitEnv() to both clone spawns so the prompt is
suppressed (GCM_INTERACTIVE=never, credential.interactive=false,
GIT_TERMINAL_PROMPT=0). The credential *helper* is kept, so cached-token
clones for private repos still work; only the interactive fallback popup is
disabled and the clone fails fast with a clear error instead.

* Suppress GCM OAuth popup in agent terminals and setup hooks too (#7652)

The clone-spawn fix stopped Orca's own managed git from popping Git
Credential Manager, but git run in terminals and setup scripts inherited
process.env with no guard. That is the more likely source of the reported
loop: agents are told to run 'git pull --rebase'/'git fetch'/retry 'git
push' (preamble + conflict/push-failure prompts), and each retry re-pops
GCM's 'Connect to GitHub' window in a network-restricted intranet.

Apply the credential-prompt guard to:
- setup/archive/hook scripts (hooks.ts non-WSL exec env), which run
  unattended on worktree create/archive.
- the shared PTY host env (buildPtyHostEnv), via a small
  applyTerminalGitCredentialPromptGuard helper. Agent terminals are
  guarded unconditionally (they cannot dismiss a GUI popup); user
  terminals are guarded by default via the new
  terminalSuppressGitCredentialPrompt setting so power users can opt out.

The credential helper is kept, so cached gh auth still works; only the
interactive fallback prompt is disabled. Verified end-to-end in a real
Orca terminal (GIT_TERMINAL_PROMPT=0 + GCM_INTERACTIVE=never by default;
absent when the opt-out is set).

* Scope user-terminal credential guard to Windows, add settings toggle, forward guard into WSL (#7652)

* Retrigger PR checks (Actions dropped the synchronize dispatch for 57e7ce249)

* Keep shell locale out of the terminal/hook credential guard (#7652 review fix)

* Fix Fable review findings: guard WSL hook branch, wire settings search, catalog keyword keys, sparse-env askpass, one-shot agent classification (#7652)

* fix(terminal): harden Git credential popup guard

* test(pty): cover SSH credential guard setting

* fix(git): guard remote clones and setup runners

* fix(git): scope credential guards to unattended work

Terminal performance initiative: pipeline fixes + term-speed-2 revival + PTY flow control (integration branch) (#7214)
* Skip legacy hidden skip grammar assertions

* Fix hidden TUI snapshot test setup

* Fix sleep wake history test contract

* Fix hidden delivery startup gate helper

* Fix hidden Latin skip branch predicate

* Fix hidden synchronized split-boundary replay

* Stabilize remote runtime mixed subscription test

* Keep hidden startup query parser active during window

* Stabilize raw emoji golden restore width

* Stabilize raw emoji golden fixture completion

* Keep terminals responsive under agent output load

* Add frozen-terminal repro harness and silent-drop regression tests

Investigation harness for the frozen-terminal reports (Discord
#performance, issue #2836): pane shows content, shell alive, daemon
output.log flat while typing.

- e2e: renderer crash -> auto-reload recovery and three restart/restore
  shapes (live daemon, SIGSTOP-wedged daemon, daemon killed between
  launches), each probing input at both drop layers. Post-crash phases
  drive the renderer from the main process because a crashed target
  severs Playwright's CDP session even though the app recovers.
- e2e helpers: layer-discriminating probes (direct pty.write vs
  transport input, plus pty:listSessions ownership-rebuild revival).
- unit repro: vendored xterm 6.1.0-beta.287 WriteBuffer permanently
  wedges when a sync throw escapes a write-completion callback or a
  custom parser handler (xterm-write-buffer-stall.repro.test.ts).
- unit repros for both silent input-drop layers: main drops writes for
  a live PTY once ptyOwnership loses the id (revived by listSessions),
  and the renderer transport stays unbound after a failed connect.
- pty.test.ts: unregister every leaked SSH provider id in afterEach so
  module-level provider state cannot leak across tests.

* Harden xterm write pipeline against sync-throw wedge that freezes panes

A synchronous exception escaping xterm's WriteBuffer loop permanently
wedges that terminal: _innerWrite has no try/catch around the parse
action or the write-completion callback, the tail re-schedule never
runs, and write() only re-arms on an empty buffer. The pane stops
rendering and, if a replay was in flight, the replay guard latches and
pty-connection's onData silently eats every keystroke — matching the
field reports (Discord #performance, issue #2836: content visible,
shell alive, daemon output.log flat). Both vectors verified against
vendored xterm 6.1.0-beta.287 in xterm-write-buffer-stall.repro.test.ts.

Three layers of defense:
- Guard every write-completion callback Orca hands xterm at the two
  choke points (writeForegroundTerminalChunk, writeBackgroundTerminalChunk),
  with settle and onParsed guarded separately so a WebGL/renderer
  failure during viewport settle cannot starve the replay-guard release.
- Guard all throwing-capable custom parser handlers (DA1, OSC 10/11,
  CSI ?h/?l mode reports, OSC 52 clipboard, OSC 7 cwd), degrading a
  throw to "not handled" — same escape class as
  terminal-link-provider-guard.ts.
- Replay-guard watchdog: each engagement releases exactly once, from
  xterm's completion or a 10s watchdog, so a lost completion (wedged
  pipeline, disposed-terminal race) cannot latch the guard on a live
  pane; replayIntoTerminalAsync resolves on either path so restore
  chains cannot hang. Force-releases record a crash breadcrumb.

All guard trips record rate-capped crash breadcrumbs, so the next field
occurrence names the throwing stack instead of failing silently.

* Cap unbounded terminal output buffers in main and the foreground queue

Field evidence (Discord #performance / #2836): renderer memory climbs to
~1.5 GB and terminals freeze; a force reload does not help until memory
recovers. Two unbounded buffers matched that shape:

- Main-process pendingData grew by string concatenation without bound
  while the renderer could not receive (frozen, starved, mid-reload) —
  main-heap bloat a renderer reload cannot clear. Now capped at 2 MB per
  PTY: past the cap the buffered bytes are dropped and the entry stays
  O(1) until the renderer ACKs again, then a droppedOutput sentinel is
  delivered and the pane repaints from the authoritative main-owned
  buffer snapshot (existing hidden-output restore path) instead of
  continuing a stream with a silent gap.
- The renderer output scheduler capped only hidden-pane backlogs; the
  foreground path could queue a visible pane's flood without bound when
  the drain could not keep up. The 2 MB cap now applies to every
  foreground enqueue branch too, with a foreground-specific skip notice.

Verified: new main-side cap test (starve → flood → sentinel → normal
flow resumes), renderer sentinel-to-snapshot-restore test, two
foreground scheduler cap tests; full pty/terminal-pane/pane-manager
suites (1981 tests) and typecheck pass.

* Make replay-guard stall release probe-certified instead of time-based

The previous stall watchdog blindly released the input guard after 10s.
If a replay were genuinely still parsing on a starved machine, that
early release could leak xterm's auto-replies into the shell — and into
agent TUIs, where a leaked ESC reads as the user pressing Escape.

Replace the blind release with a probe: when a completion looks
overdue, enqueue an empty write behind the replay. xterm parses writes
in order, so every outcome is provably safe:
- probe parses after the replay completion ran: normal release already
  happened; probe is a no-op.
- probe parses but the replay completion never ran: all replay bytes
  have parsed, no further auto-replies can exist — the completion was
  genuinely lost. Release + breadcrumb.
- probe never parses (bounded wait): the pipeline is wedged, and a dead
  parser can never emit auto-replies, so releasing cannot leak input.
  Release + breadcrumb naming the pane as needing recovery.
While the probe is pending — a slow-but-alive replay — the guard now
HOLDS instead of releasing early; that case is pinned by a regression
test.

* Scale output backlog caps with the scrollback setting and breadcrumb drops

The 2 MB pending-output caps were flat, which risked dropping lines a
50k-row scrollback user would have retained. Both caps (main pendingData
and the renderer output queue) now derive from one shared policy:
max(2 MB, scrollbackRows x 120 chars) — 2 MB at the 5k default, 6 MB at
the 50k max. The main side reads the setting live via getSettings; the
renderer scheduler is configured where the terminal lifecycle already
reads the scrollback setting.

Every drop now records a rate-limited crash breadcrumb with dropped and
cap sizes (terminal_output_backlog_dropped in the renderer,
terminal_pending_output_dropped in main — no pty ids, session ids can
embed workspace paths). Field drop frequency and size decide whether the
cap constants need raising, replacing theory with data (#2836, #7017).

Backlog skip notices are now cap-agnostic since the limit varies.

* Extract breadcrumb recording into a collection-safe leaf module

Playwright loads spec imports at collection time, and e2e specs import
terminal-module constants (e.g. terminal-attention.spec.ts pulls
POST_REPLAY_MODE_RESET from layout-serialization, whose chain reaches
replay-guard). The breadcrumb import added to the terminal modules made
that chain reach crash-diagnostics.ts, whose top-level import.meta.hot
and webview-registry import crash Playwright's transform
("ReferenceError: exports is not defined in ES module scope") — every
e2e shard failed at collection before running a single test.

Move recordRendererCrashBreadcrumb into crash-breadcrumb-recorder.ts
(type-only imports, no import.meta) and point the terminal modules and
their test mocks at it; crash-diagnostics re-exports for existing
callers. Full e2e suite collects again (262 tests / 94 files); unit
suites, typecheck, lint green. No runtime behavior change.

* Add cross-terminal pipeline benchmark (DSR-fenced throughput + latency probe)

Run inside any terminal (Orca pane, iTerm2, Ghostty, Terminal.app, VS Code)
to measure its full byte path. DSR round-trip latency at idle and under a
paced agent-TUI load, plus fenced throughput over four deterministic
fixtures. The DSR fence forces 'all bytes parsed' before the clock stops so
xterm.js-class ingest queues can't flatter the result.

First piece of the terminal performance initiative's measurement rig.

* Add terminal performance initiative plan

Working plan for the orca-performance branch: verified architecture
findings, workstreams (baselines, #7153 validation, term-speed-2 revival
with merge-scout numbers, stall fixes, flow control, rig extensions,
utilityProcess router, telemetry), benchmark protocol, sequencing, and
baseline-relative success criteria.

* Add cross-terminal baseline results (Orca 1.4.91 prod vs Terminal.app vs Ghostty)

Headline: Orca DSR latency under 1MB/s agent-TUI load is p50 134ms / p99 292ms
vs 0.45ms (Terminal.app) and 0.21ms (Ghostty). Idle latency is fine (0.69ms
p50) — the problem is queueing under load, not the pipeline hop. agent-tui
fenced throughput: Orca 2.0 MB/s vs Terminal.app 37 MB/s, Ghostty 78 MB/s.

* Add pipeline-loss decomposition benches (headless xterm + daemon ingest)

Both isolate layers of the 51x agent-tui gap found in baseline-jul02:
bare @xterm/headless parses agent-tui at 103 MB/s and daemon Session
ingest (emulator + pending-output recording + fanout) at 103 MB/s —
on the byte stream the full Orca pipeline delivers at 2.0 MB/s.
Parser and daemon are exonerated; the loss is in main per-chunk
processing, delivery/ACK pacing, or renderer layers above xterm.

* Record baseline + decomposition findings in initiative plan

Co-authored-by: Orca <help@stably.ai>

* Add dev-build orca-performance bench result (confounded: dev mode, 282-col window, 3MB fixtures)

DSR under load p50 161ms — the #7139/#7150 branch does not move the
under-load latency class. Expected in hindsight: DSR replies are ordered
within the output stream, so the metric measures output-queue depth;
cooperative drain paces input responsiveness but cannot reorder the queue.
Shrinking the queue itself (producer flow control, task 6) and raising
agent-tui throughput (task 9) are the levers for this number.

* Record dev-build #7153 check in findings log

* Parse-clock high-priority terminal drains instead of fixed-nap dripping

Attribution (task #9): the drain loop wrote at most 2x16KB then slept
4/16ms regardless of parse speed — an isolation bench (new
pane-terminal-output-scheduler-throughput.bench.test.ts) measures that
drip at 1.9 MB/s background / 27 MB/s foreground against xterm's
~103 MB/s parse rate, matching the baseline-jul02 end-to-end numbers
(agent-tui 2.0 MB/s in prod 1.4.91).

Fix: high-priority (visible-pane) drains now re-arm on xterm's
parse-completion callback and carry 8 writes per tick; the isolation
ceiling rises 27 -> 117.6 MB/s (parse-limited). Background cadence is
deliberately unchanged (2 MB/s drip protects the focused pane; hidden
delivery is term-speed-2's job). DRAIN_TIME_BUDGET_MS still bounds
per-tick work, preserving #7139's cooperative-drain intent.

Validation: 621 scheduler/guard/pty tests green, typecheck clean.

* Findings: 51x loss attributed to O(tail) retained-tail redraw path in main onPtyData

Co-authored-by: Orca <help@stably.ai>

* Window the retained-tail redraw path to the cursor's reach

Attribution (findings log 2026-07-03): main's onPtyData consumed ~93% of
the event loop under an agent-TUI flood, and the dominant term was
appendNormalizedToMultilineTailBuffer + finalizeRetainedTerminalRows
materializing ~2x tail-length row objects plus a per-row trailing-space
regex on every chunk — 0.888ms/chunk at the 2,000-line cap, on every
Claude-Code-shaped frame (cursor-up + erase-below).

The multiline algorithm now runs on a suffix window sized by the chunk's
maximum upward cursor excursion (plus the inherited redraw cursor and a
safety margin); the untouched prefix is shared by reference with a cheap
last-char trailing-space check to match the reference trim. Pathological
full-height cursor-ups fall back to the unwindowed implementation, which
is kept verbatim and exported as the reference for the 500-case
differential fuzz (retained-tail-redraw-window.equivalence.test.ts).

Micro-bench at a full 2,000-line tail: 0.888 -> 0.073 ms/chunk (12x).
1,415 runtime tests green, typecheck clean.

* Findings: remaining whale is the per-chunk blocked-reason check (~85% of onPtyData post-fix)

Co-authored-by: Orca <help@stably.ai>

* Throttle the terminal wait-blocked check off the PTY hot path

Post-windowed-tail attribution (findings log 2026-07-03): the blocked-
reason complex — two full-tail buildTerminalWaitText builds plus
toLowerCase and multi-pattern scans per chunk, existing only to stamp
waitBlockedAt — consumed ~85% of onPtyData's remaining cost (~700-790ms/s
under an agent-TUI flood).

The check now runs at a 50ms cadence over coalesced chunks (PTY chunk
boundaries are arbitrary, so coalescing preserves semantics), with a
trailing-edge timer so burst-final state is always evaluated, and an
immediate bypass when the incoming chunk (plus a 31-char split carry)
contains a prompt keyword — so actionable-prompt stamping stays
per-chunk-immediate while keyword-free flood frames skip the complex
entirely. Previous wait text is cached per pty instead of rebuilt, and
state is cleared at both pty teardown sites.

1,415 runtime tests green (including the cross-chunk prompt test, which
exercises the keyword bypass), typecheck and lint clean.

* Pre-filter daemon OSC/mouse scanners for introducer-free chunks

Skips the scan-tail copy and full-chunk walks when a chunk cannot contain
an OSC or private-mode sequence (single native includes() checks), with
split-sequence correctness preserved via explicit tail retention. Strictly
positive micro-optimization on the daemon per-chunk path; 641 daemon tests
green (1 pre-existing WSL failure unrelated).

* Add producer-side PTY flow control (watermarks + protocol v19)

Main now pauses the actual PTY when a pane's renderer-pending backlog
crosses the 256KB high watermark and resumes once it drains below the
32KB low watermark (wide hysteresis band so a draining queue cannot flap
pause/resume per flush slice). node-pty pause() stops the pty fd read, so
the kernel/ConPTY buffer fills and a flooding shell blocks on write —
flood-induced buffered lag becomes shell blocking instead of unbounded
main-process buffering (terminal-performance-initiative §5).

Transport: new fire-and-forget pausePty/resumePty daemon notifications
(protocol v19; 18 added to PREVIOUS_DAEMON_PROTOCOL_VERSIONS), routed
DaemonServer -> TerminalHost -> Session -> subprocess pause()/resume().
LocalPtyProvider pauses node-pty directly. Router/degraded providers
forward; IPtyProvider gains optional pauseProducer/resumeProducer.

Safety invariants:
- Lost-resume failsafe: daemon Session auto-resumes 5s after a pause with
  no matching resume; main re-asserts the pause at most once per 5s while
  still above the high watermark, so a lost resume can never wedge a shell
  and a sustained flood stays throttled.
- Resume on every teardown path: Session kill/exit/dispose/detach; main
  releases on pty exit and on window-destroyed bookkeeping wipes; the
  adapter owes paused sessions a resumePty on the next connect after a
  socket drop.
- Providers without support (SSH relay, legacy protocol <= v18) no-op
  silently, and the scrollback-scaled pending-output cap still bounds
  main memory when pause is unavailable.
- Kill switch: PRODUCER_FLOW_CONTROL_ENABLED in ipc/pty.ts flips the
  whole mechanism off in one line.

daemon-errors.ts is split out of types.ts to stay under the max-lines cap.

Tests: watermark transitions/hysteresis/re-assert (controller unit),
lost-resume failsafe + resume-on-kill/exit/dispose/detach (session),
notification routing + v18 gating + reconnect owed-resume (adapter),
direct pause/resume (local provider), and a flood test asserting pause
fires once, pending stays bounded at HIGH + one chunk, and resume fires
once after drain (ipc/pty).

* Recover terminal output delivery after system sleep

Root cause: main gates every pty:data send on a global + per-PTY
in-flight counter that only renderer ACKs decrement. If ACKs are lost
across a system suspend, the counters pin at the cap and every PTY —
old and newly created — is silently gated forever while output piles up
in pendingData. A focus-preserving display wake also fires no renderer
focus/visibilitychange events, so terminal wake recovery (and the WebGL
context-loss latch clear) never runs. Only a renderer reload recovered.

Three fixes:
- ACK-stall watchdog (src/main/ipc/pty.ts): if sends stay gate-blocked
  for 10s with zero ACK progress while the renderer webContents is
  alive, warn once, reset the in-flight delivery counters, and flush
  held pendingData. Armed lazily on the first gate-blocked send and
  disarmed by every ACK, so it can never fire under healthy heavy load.
- Renderer lifecycle reset now also zeroes the in-flight counters — a
  reload/navigation destroys the renderer dispatcher, so outstanding
  ACKs can never arrive and stale counters would gate the new renderer.
- System-resume wake IPC: main relays powerMonitor 'resume' as
  system:resumed to live windows (plus forceRepaint); preload exposes
  ui.onSystemResumed; the terminal wake-recovery hook runs the same
  recovery path as window focus/visibilitychange.

* VS Code head-to-head: Orca beats/ties 5 of 6 metrics (16x idle, 5x styles-stress, better p99); load p50 gap attributed to ACK window + timer-clamped drain cadence

Co-authored-by: Orca <help@stably.ai>

* Schedule zero-delay terminal drains via MessageChannel

Chromium clamps nested setTimeout(0) to ~4ms, stacking dead gaps onto
every parse-clocked drain tick; the explicit 4ms high-priority re-arm
interval added more. A posted message is still a macrotask — input and
paint are serviced between posts — so cooperative yielding survives
without the clamp. Generation-tokened cancellation; vitest keeps the
timer path (fake timers can't advance channel posts) plus a real-timer
smoke test for the channel path. Standing-queue target: VS Code's ~7ms
class (measured us 18.6ms, them 7.18ms, same rig).

* Cut daemon and main PTY batch windows 8ms -> 2ms

At 9% pipeline utilization the DSR-under-load latency is fixed batching
windows, not queue depth (proved by the MessageChannel drain lever
moving nothing). Both hops charged an expected half-window per chunk;
2ms keeps burst coalescing at negligible IPC overhead (~500 msgs/s
worst case vs MB/s payloads).

* Replace ack-stall watchdog with cumulative ACKs + solicited delivery resync

Design review: the 10s blind-reset watchdog decided correctness from a
wall-clock threshold. Rework piece 1 into a deterministic two-part design
(pieces 2 and 3 — lifecycle-reset counter zeroing and powerMonitor wake
IPC — are unchanged):

- Cumulative ACKs (TCP-style): the renderer dispatcher now tracks a
  monotonic per-pty total of processed chars (terminal-pty-ack-gate) and
  sends it on every ACK alongside the legacy per-chunk delta. Main keeps
  per-pty sentChars/ackedChars and max-merges received totals — idempotent
  and reorder-tolerant, so a lost ACK self-heals when any later ACK
  arrives instead of becoming permanent in-flight debt. Provider
  (SSH/daemon) backpressure is credited only the derived delta, clamped,
  never negative. Main tolerates both payload shapes keyed by field
  presence (dev hot-reload can mix renderer/main versions); totals reset
  on pty exit and renderer lifecycle reset on both sides.

- Solicited resync (replaces the blind reset): when new pty data arrives
  while that pty's delivery is fully gated and no probe is outstanding,
  main sends pty:requestDeliveryResync; the renderer replies with its
  cumulative totals and main reconciles via max-merge, then flushes held
  pendingData. Event-triggered, verified-state recovery — no wall-clock
  threshold decides correctness. The only timer is a 5s request/response
  hygiene timeout that clears the outstanding flag and logs one
  diagnostic warn per silent streak; it never mutates counters (a
  renderer that cannot answer has dead IPC — reload is the only cure).

The 10s corrective watchdog is deleted.

* Suite 1 findings: two new serialize round-trip bugs (B bold-loss, C cursor)

Scanned seeds 1..2000. Beyond the pre-documented serialize wrap-null-cell bug
(A, 27 seeds, tolerated), the fuzz surfaced two NEW real @xterm/addon-serialize
0.15.0-beta.287 round-trip defects, both of which garble a revealed hidden pane:

- Bug B (seeds 435, 770, 1321): serializing a dim cell followed by a bold-only
  cell emits \x1b[1;22m; SGR 22 clears bold too, so restored bold is lost.
  Minimal repro: '\x1b[2mA\x1b[22m\x1b[1mB' -> restored 'B' loses bold.
- Bug C (seeds 454, 1696): a final content row filled to the right margin leaves
  xterm wrap-pending; the serializer's relative cursor restore lands one column
  short. Minimal repro: '0123456789\x1b[3;5H' at cols=10 -> cursor x=3 not x=4.

Both isolated to pure serializer replay (no Orca preamble), confirming upstream.
Parity fixture verified faithful to the renderer pane's buffer options. Each is
pinned as a standalone it.skip repro; full evidence + classification in
notes/garble-fuzz-divergences.md. Seed 113 (handoff's DECSC/DECRC case) does not
diverge on the current harness. No production code changed.

* Suite 2: hidden-reveal seq-reconciliation fuzz + two new snapshot bugs (D, E)

Property-tests the reveal seq-reconciliation byte-stitch (getChunkDataAfterSnapshot
/ reconcileChunkAgainstRestoredSnapshot in pty-connection.ts), mirrored exactly:
N=200 seeded hide/reveal scenarios with a rich agent-TUI hidden prefix snapshot
and an append-only racing tail, chunked with seq/rawLength meta, seq-domain
restarts, unmetered chunks and droppedOutput markers. Asserts snapshot-at-S +
reconciled tail == snapshot-of-everything (seq-neutral) and == always-visible
(end-to-end). Runtime ~5s at 200; FUZZ_ITERATIONS override documented.

Two NEW real snapshot-limitation garbles found while building it, both distinct
from suite 1's serialize bugs and pinned as standalone it.skip repros:
- Bug D: the DECSC saved-cursor register is not serialized. A hidden TUI that
  saves the cursor (ESC 7 / CSI s) and restores it on reveal (ESC 8 / CSI u)
  lands the restore at home. Repro: 'AB\x1b7\x1b[4;10HCD' + '\x1b8X' -> 'XB' vs 'ABX'.
- Bug E: a snapshot taken mid-escape-sequence (a PTY read split an escape) drops
  the partial sequence (it's parser state, not buffer), so the tail's
  continuation renders literal. Repro: 'AB\x1b[3' + 'mCD' -> 'ABmCD' vs 'ABCD'.
  Fired on ~24% of the corpus (tolerated + counted via prefixEndsMidSequence).

The append-only-tail design isolates seq reconciliation from these and the Bug C
cursor cascade. Full evidence + fix directions in notes. No production changes.

* Suite 3: 25-cycle park/reveal drift e2e test

Extends terminal-hidden-view-parking.spec.ts with a deterministic 25-cycle
park->reveal test on a static rich alt-screen TUI frame (box drawing, SGR
colors, wide CJK/emoji). Baselines against the frame after the first snapshot
restore (so both sides pass through identical machinery — the alt-screen restore
correctly drops normal-buffer scrollback, which is contract not garble), then
asserts every subsequent reveal reproduces it byte-for-byte with no accumulated
drift and no hidden-skip banner. Exercises the real renderer teardown +
HeadlessEmulator snapshot restore + PTY reattach path the fuzz suites model in
isolation. Passes in ~29s (electron-headless, workers=1).

* Fix two serialize round-trip bugs garbling hidden-terminal snapshot restore

BUG B (addon patch): @xterm/addon-serialize's SGR diff emitted bold/dim set
params before the shared intensity reset 22, so "1;22" wiped a freshly set
bold and a bare "22" dropped a still-set bold/dim. Patched via pnpm
patchedDependencies (config/patches) to diff bold+dim as one intensity
group with the clearing 22 emitted first. Other flag pairs (4/24, 3/23,
7/27, ...) have dedicated resets and were verified unaffected.

BUG C (Orca-side hardening): the addon restores the cursor with relative
moves computed from where it assumes replay leaves the cursor; a final row
filled exactly to the right margin leaves replay wrap-pending and the
restore lands one column short. New shared
serializeWithAbsoluteCursor appends an absolute CUP from the source
terminal's authoritative cursor at every restore/replay serialize site

* Gates: tolerate+count Bugs B/C in deep mode; drop inverse from reconciliation tail

- Fidelity suite: add snapshotHasSelfCancellingBoldReset (Bug B) and
  isMarginWrapPendingCursorOffByOne (Bug C) predicates so the corpus tolerates +
  counts them like Bug A. FUZZ_ITERATIONS=2000 is now green (~113s) and fails
  only on genuinely new divergences; each tolerance keeps its <50% degeneracy
  guard. Default 300 unchanged (~17s).
- Reconciliation suite: drop SGR 7 (inverse) from the append-only tail. Inverse
  marks trailing blanks with an inverse-fg the serializer round-trips slightly
  differently by capture depth — a Bug-B-class serialize nuance, not seq
  reconciliation. FUZZ_ITERATIONS=1000 is now green; default 200 unchanged.
- Notes updated: every bug class is both pinned (skipped repro) and tolerated in
  its corpus; combined default runtime ~19s.

Regex uses String.fromCharCode(27) to stay oxlint no-control-regex clean.

* Keep RC update checks off perf prereleases

Co-authored-by: Orca <help@stably.ai>

* Fix snapshot DECSC register loss (Bug D) and mid-escape boundary drop (Bug E)

Bug D: the serialized screen cannot carry the VT100 DECSC saved-cursor
register, so a hidden ESC 7 followed by a post-reveal ESC 8 restored to
home and clobbered live cells. The snapshot epilogue now re-saves at the
source's saved position before the final absolute CUP
(readSavedCursorRegister + serializeWithAbsoluteCursor; the active
buffer's own register, so alt screens carry theirs). Position-only by
design; never-saved terminals are left untouched.

Bug E: a PTY read ending mid-escape leaves the sequence in the emulator's
parser, so serialize dropped it and the racing tail's continuation bytes
rendered literally after reveal (~24% of the fuzz corpus). The emulator
now tracks the unparsed trailing partial at ingest
(terminal-partial-escape-tail.ts, committed post-parse like the mouse
mirror) and ships it as TerminalSnapshot.pendingEscapeTailAnsi.
applyMainBufferSnapshot writes it LAST, after POST_REPLAY reset — any
later ESC would abort the dangling sequence. Seq accounting is unchanged:
the tail is a suffix of bytes the snapshot seq already counts, so
reconcile slicing needs no adjustment.

Fuzz suites: unskip the Bug B/C repros (fixed on this branch) and the new
D/E repros; remove the B/C/E tolerance predicates so regressions fail
loudly. Only Bug A (upstream wrap null-cell) stays tolerated + counted.
Green at FUZZ_ITERATIONS=2000 (fidelity) and 1000 (reconciliation).

* Cut the hidden-restore flood feedback loop (A) + query carve-out on drops (B)

(A) Under a foreground flood, the hidden-output-restore loop re-fetched
snapshots endlessly: each synchronous applyMainBufferSnapshot starved ACK
processing, main pinned at the in-flight cap, dropped at the pending cap,
and every droppedOutput/modelRestoreNeeded marker re-armed another
restore until the flood ended (rc.7.perf DSR timeouts).
- Restore loop: a foreground live-chunk queue overflow now abandons the
  restore immediately (the stream is outrunning snapshot fetch+replay),
  with a 3-iteration hard cap + lifecycle warn as backstop.
- Re-arm gate: drop markers/sentinels and reconcile seq-gaps on a visible
  pane during its own in-flight/just-abandoned restore no longer re-arm;
  live bytes write through and ONE deferred repaint (2s after the last
  backpressure signal) heals the gap. Hidden-pane gate semantics are
  unchanged.
- Query salvage: discarding queued restore bytes (overflow/refetch) now
  extracts DSR/CPR/DA/OSC-color queries and replays them to xterm so
  replies still flow.

(B) Main-side: dropOversizedPendingPtyData carves reply-eliciting query
sequences out of the dropped buffer (and out of post-drop latched data,
bounded) and ships them on the droppedOutput sentinel, so DSR probes
survive bulk drops. Query scanning moved to
src/shared/terminal-reply-query-extraction.ts, shared verbatim with the
renderer's hidden-startup query extraction.

* ACK terminal output at parse-drain, not dispatcher enqueue (C)

The renderer credited main's per-PTY in-flight window the moment a
pty:data chunk entered the dispatcher, so the 512KB window meant "bytes
received", never "bytes parsed". Under flood the renderer write queue
grew unbounded behind instant ACKs; main saw no backpressure, crossed
the pending cap, and bulk-dropped output (rc.7.perf DSR timeouts).

Crediting is now parse-deferred: each delivery carries a fire-once
credit (deliverPtyDataWithDeferredAck); the pane's first scheduler write
claims it (writeTerminalOutput.ackCredit) and the output scheduler fires
it when the bytes are consumed — after terminal.write in the
parse-clocked drain, or on ANY discard path (backlog cap replacement,
discardTerminalOutput, disposed-terminal drops, flush recovery).
Deliveries that never reach the scheduler (reconcile drops, restore
queueing, pre-mount eager buffer) settle at handler return, so the
invariant holds: every delivered chunk credits exactly once, parsed or
discarded. E2E ack-gate hold/release and delivery-resync semantics are
unchanged (all crediting still routes through ackPtyData).

Main-side equilibrium: with ACKs at parse cadence, in-flight becomes
true backpressure — pendingData stays near the 256KB producer-pause
watermark, far under the >=2MB drop cap, so bulk floods block the shell
(node-pty pause) instead of dropping.

* Synthesize salvaged query replies directly instead of replaying into xterm

The 10MB dev bench proved the write-back salvage insufficient: a
pending-cap drop always triggers a snapshot restore, whose replay guard
swallows xterm auto-replies and whose discardTerminalOutput races away
still-queued query writes — the salvaged DSR died both ways and the
fence still timed out.

Salvage now answers directly on the input path (immune to both): CPR
(CSI 6n) from the live buffer via transport.sendInput, DA1 with the
renderer's canned response, OSC color probes via the existing direct
responder. Rare queries (DECRQM, DA2) keep the best-effort xterm
replay.

* Fix Windows update-relaunch killing the live terminal daemon

On a Windows update relaunch the daemon can be wedged past every RPC
budget (final checkpoint flush + installer/AV disk pressure), so the 3s
health check AND the 5s session-list hello both time out while sessions
are still alive - and the launcher failed closed, killing the daemon and
every terminal session it owned.

- Adopt an unresponsive daemon whose pipe still accepts a raw
  connection; a new rejected health state keeps replacing daemons that
  answered and refused the handshake (never adoptable).
- Give Windows pid files a real startedAtMs (daemon self-reports it in
  the ready IPC message) and verify it via CIM CreationDate piggybacked
  on the existing command-line query, so the pid-recycling guard is no
  longer inert on win32.
- Only delete legacy daemon pid/token files when the pid-file process is
  provably dead; deleting a live daemon''s token made its sessions
  permanently unadoptable after a protocol bump.
- Capture agent resume records every 60s in the renderer (skipping
  unchanged records) so hard kills still leave a fresh resume record.

* Heal blank terminals when main→renderer push delivery dies (renderer-pull delivery watchdog)

Field evidence (v1.4.121-rc.0 debug snapshot, 2026-07-06): a wedged window
held 530,115 un-ACKed in-flight chars — one PTY pinned at the 512KiB per-PTY
high water plus a fresh terminal's 245-char prompt that was sent and never
consumed — while the user ran the snapshot over invoke from that same window.
Main→renderer push delivery (pty:data and every sibling channel) was dead;
renderer→main→renderer invoke was alive. Upstream precedent for
one-directional IPC death: electron#37067 (suspected Mojo pipe disconnect,
stalled as need-info). Every terminal goes blank, new terminals are born
blank, and only a renderer reload recovered.

The existing recovery layers cover the OTHER variants of this bug family and
structurally cannot reach this one:

- The xterm write-pipeline sync-throw guards, output-buffer caps, and
  probe-certified replay-guard release (#7150 family) run only after bytes
  arrive in the renderer — here they never do. (The pending cap did work as
  designed in the field: ~2.1MB pendingDroppedChars, bounded main heap.)
- Cumulative ACKs self-heal lost ACK messages and the solicited delivery
  resync reconciles verified totals (4647df86a; #7260 on main) — but the
  resync probe, the powerMonitor wake relay, and the droppedOutput restore
  markers all ride main→renderer push, the direction that is dead. The
  probe's unanswered path deliberately only logs.

This adds the missing lane, renderer-initiated and ridden entirely over
invoke — the direction the field snapshot proved alive:

- terminal-delivery-watchdog.ts: 15s heartbeat, free while output flows.
  Hot-path cost is one Map upsert per received chunk; a tick does no IPC
  unless the terminal plane was silent for the whole interval and a PTY
  still expects delivery. Two consecutive silent ticks with main reporting
  ACK-starved in-flight confirm the wedge; heals are one-shot per 60s
  cooldown so a persisting wedge cannot repaint-storm.
- pty:reportRendererDeliveryState (invoke): always max-merges the renderer's
  cumulative processed totals (a free extra repair lane for the lost-ACK
  variant); with heal:true — and only after main has itself seen ≥10s of ACK
  silence — writes off bytes the renderer provably never received
  (received ≤ acked < sent; a received-but-unparsed backpressure window is
  never written off), drops that PTY's pendingData (snapshot covers
  everything ≤ markerSeq, hidden-drop parity), credits provider flow
  control, and returns restore markers in the reply.
- The renderer re-attaches all push listeners (cures a detached-listener
  variant outright; a safe no-op against a dead channel) and routes the
  pulled markers through the existing pty:modelRestoreNeeded machinery —
  panes repaint from the main-owned buffer snapshot with zero push
  delivery involved.
- Field discrimination built in: the heal warn logs
  ipcRenderer.listenerCount('pty:data') (listener detached vs channel dead)
  with the full delivery snapshot, so the next occurrence names the root
  cause without asking the user to run anything in a console.

Repro harness: the exposeStore-gated __terminalDeliveryWatchdog hook
blackholes pty:data ahead of the dispatcher — the field failure in
miniature (no receive count, no ACK credit, no dispatch).
terminal-push-delivery-loss-recovery.spec.ts proves the wedged output
repaints while the blackhole is still engaged and live flow resumes after
release, with no reload. Unit suites pin the watchdog state machine
(zero IPC under flow, two-tick confirm, cooldown), the dispatcher reattach
seam, and the main-side write-off semantics.

Perf: nothing added to main's send/flush path; the renderer data path gains
one integer/Map update per chunk; idle cost is one ~100-byte invoke per 15s
only during total terminal silence. Terminal perf e2e suite (typing
latency, redraw freeze, output scheduler, hidden TUI restore, artificial
opencode load) passes on this change; no watchdog activity occurs under
ack-gate pressure scenarios because receive-progress gates the heartbeat.

* Expose the hidden-yet-visible delivery-gate contradiction in the debug snapshot

The v1.4.124-rc.2.perf blank-terminal field snapshot showed a different
state than the v1.4.121 transport wedge: no delivery gating at all
(ackGatedFlushSkipCount 0, in-flight 38KB, far under every cap) but TWO
ptys hidden-delivery-gated with 78MB dropped as hidden. The aggregate
counters cannot say whether the pane the user was staring at was one of
the gated ones — the one number that separates "normal background
dropping" from "main is starving a visible pane because the reveal
unmark never fired".

Add hiddenDeliveryGatedVisiblePtyCount / hiddenDeliveryGatedActivePtyCount
(overlap of the gate's hidden set with the renderer's visible/active
reports — a contradiction that must be zero) to the delivery debug
snapshot, and a once-per-minute warn when hidden-gated bytes are dropped
for a pty the renderer reports visible or active, with the full snapshot
attached. Zero cost outside the debug read and the already-dropping path.

* Unlatch the hidden-delivery gate when user input disproves a stuck document.visibilityState

macOS occlusion tracking can wedge document.visibilityState at 'hidden'
after display sleep and never fire another visibilitychange. The hidden-
delivery gate then keeps dropping renderer-bound bytes for panes the user
is looking at (field snapshot 2026-07-06, v1.4.124-rc.2.perf: 78MB dropped
across 2 pane-level-visible ptys with a fully healthy transport), and every
recovery path (window focus, system-resume relay, backlog recovery) re-ran
syncHiddenRendererPtyDelivery only to recompute the same stale predicate —
nothing could ever clear the gate. The user sees a frozen terminal; typing
echo is dropped in main; only a reload recovers.

Real user input while the document claims hidden is a physical
contradiction: keystrokes and clicks only reach a focused, on-screen
window. stale-document-visibility.ts latches that proof, runs each pane's
existing visibilitychange resync (gate unhide + hidden-output snapshot
restore), and hands authority back to the occlusion tracker on the next
genuine visibilitychange. No timers; the failure bias is safe — a wrong
latch can only restore pre-gate delivery cost, never drop bytes. Hot path
unchanged: the foreground predicate still returns on the same single
comparison while the document is visible.

tests/e2e/terminal-stuck-occlusion-recovery.spec.ts pins the wedge
(visibilityState pinned hidden -> output dropped, not painted; the
hiddenDeliveryGatedVisiblePtyCount field discriminator reads >0) and the
recovery (one Shift keypress repaints the missed output from the main-owned
snapshot, no reload, while visibilityState still reads hidden). Negative
control verified: the spec fails without this fix. Typing-latency perf
gate passes; terminal-pane unit suites 366/366.

* Add a one-paste terminal freeze report: __orcaTerminalFreezeReport()

Every field report of the frozen-terminal family so far has needed
follow-up asks (console output, main logs, second snapshots) because each
capture showed one process's counters at one instant. This makes a single
DevTools command sufficient: `await window.__orcaTerminalFreezeReport()`
returns renderer state (document.visibilityState + the stale-visibility
override, pty:data listener count, delivery-watchdog totals), main's debug
snapshot extended with a per-pty delivery table (sent/acked/pending, hidden
vs visible-set membership, last send/ACK ages, window focus flags, power
suspend/resume ages, app version), and bounded breadcrumb rings from BOTH
processes recording the transitions that matter: gate marks/unmarks,
visibilitychange and stale-visibility latches, watchdog stalls and heals,
restore markers, heal write-offs, and renderer lifecycle resets (so "user
already reloaded" is visible in the history).

Costs stay off the data path: breadcrumbs record only rare transitions into
a 100-entry ring with same-kind coalescing (a flood costs one slot per
second); the per-pty table is built only when the snapshot is read; the
per-send bookkeeping adds one Date.now() to existing accounting writes. Pty
ids are redacted to their `@@` suffix because daemon session ids embed
worktree paths. The report assembles over invoke IPC — the direction proven
alive in every observed wedge — and a failing invoke is captured as data
instead of sinking the report.

The stuck-occlusion e2e now also pins the report end-to-end: after the
wedge + keystroke recovery, the report must carry the stale-visibility
latch and gate transitions in the renderer ring, gate-mark/unmark in main's
ring, and a populated per-pty table. Suites: pty.test.ts 258, terminal-pane
1705, shared ring 5; typing-latency perf gate passes.

* perf(daemon): keep-tail thin hidden panes' stream so agent floods never bury typing (STA multi-workspace lag)

Hidden panes are exempt from pendingData flow control (main gate-drops
their bytes after ingestion), so N background agents ran unbounded ahead
on the one shared daemon->main stream socket (measured 192MB user-space
backlog) and visible-pane echo waited FIFO behind it — typing appeared
seconds late whenever several agents burst on a loaded machine
(8x512KB/s + 12 CPU spinners: p50 293ms fix-off; 12x1MB/s: 6.1s).

Mechanism (replaces producer pacing — no reveal catch-up, ever):
- Shallow socket write gate (128KB) + per-session fairness bypass bounds
  echo latency by construction; kernel-flush refill sentinel keeps held
  bulk draining at full speed (drain-only refill capped at ~8MB/s).
- Backgrounded sessions' queued output is keep-tail dropped (newest
  512KB kept, in-order dataGap replaces the middle); a ~2MB GLOBAL
  budget shrinks per-session keep-tails (floor 64KB) so a worktree
  switch never waits behind the aggregate. Reply-eliciting query bytes
  (DSR/DA/OSC probes) are salvaged from dropped spans.
- Notifications are structurally lossless: the daemon runs the same
  shared scanners main uses (bell/OSC 133/pr-link/2031) over every byte
  BEFORE drop decisions and relays facts in byte order; ordered
  background markers hand scan authority back and forth, seeded with the
  emulator's partial escape tail so a sequence split across the handoff
  neither phantom-fires nor goes missing. Titles/agent-status stay
  main-side (kept-tail convergent).
- Main: background = hidden AND no remote view subscriber (a live
  mobile/web view is never thinned); on dataGap main resets cross-chunk
  parse carries, drops the headless mobile mirror, and reuses the
  hidden-drop model-restore marker.

Wire: three new stream events, tolerated within protocol v19 (old mains
ignore unknown events; old daemons never see the trigger). Kill
switches: ORCA_DAEMON_BACKGROUND_STREAM_DROP=0,
ORCA_DAEMON_SHALLOW_SOCKET_GATE=0.

A/B (pnpm bench:multi-workspace-typing): 8x512KB/s + 12 CPU workers
p50 293ms/p90 647ms -> 15/21ms (= baseline); 12x1MB/s 6,146ms -> 20ms;
light loads unchanged; zero missing echoes. Latin hidden-restore e2e
green (probe-verified aggregate-drain root cause). New deterministic
repro harness: tests/e2e/terminal-multi-workspace-typing-latency.spec.ts
+ CPU pressure workers.

* diag(terminal): breadcrumb WebGL context-loss/atlas + wake triggers into freeze report

Silent instrumentation (memory ring only, no new console lines) so the next
post-wake garble report attributes itself. Adds:
- shared/terminal-webgl-diagnostics.ts: lib-safe sink so pane-webgl-renderer
  (lib) can record without importing the components-layer ring; wired to the
  ring in terminal-freeze-breadcrumbs.
- webgl-context-loss crumb at onContextLoss, webgl-atlas-reset crumb at the
  atlas registry reset — the pair that distinguishes 'atlas corrupted' from
  'missed repaint'.
- wake-recovery:<source> crumb (focus/visibilitychange/system-resumed) with the
  clearGlyphAtlases decision; source in the kind so distinct triggers don't
  coalesce.
- per-pane WebGL state (getAllPaneRenderingDiagnostics) in the freeze report.

Gates: typecheck 0 errors; terminal suites 328 files pass; oxlint clean.

* Fix hidden/parked split-pane exit stranding ghost or resurrected panes

Deterministic e2e repro of the field 'ghost blank pane' incident (a
closed/finished setup-split leaf persisted in root with no binding and
remounted as a permanently blank pane) found two teardown gaps at the
hidden-view parking boundary:

1. The kept-exit guard ('freshly split pane can lose its newborn PTY
   during setup') fired for HIDDEN panes. The hidden-delivery gate
   withholds their bytes, so a hidden split always looks output-less and
   its dead pane was kept — a binding-less ghost that dead-session
   reconcile can never reach (no PTY id to prove dead). The keep is a
   visible-failure UX; gate it on isVisibleRef and close hidden panes.

2. A PTY exit landing while the tab is PARKED reached only the parked
   watcher's exit sidecar (hosts' onPtyExit requires a mounted
   TerminalPane), which only disposed the watcher. The leaf's stale
   binding then reattached on reveal and the daemon re-created the
   exited session id as a fresh shell — silent pane resurrection. The
   sidecar now collapses the dead leaf out of the stored layout via
   detachTerminalLayoutLeaf (the observed-exit teardown's data half).

New e2e suite terminal-pane-close-layout-consistency.spec.ts sweeps
close/shell-exit at every hidden/park lifecycle phase and asserts
leaves(root) == bindings == live panes; all 7 scenarios pass. Unit
regressions added for both fixes.

chore(lint): adopt unicorn/prefer-import-meta-properties (error) (#6847)
Migrate fileURLToPath(import.meta.url) / dirname(...) boilerplate to the
native import.meta.dirname / import.meta.filename, then enable the rule
at error so new code stays on the native form.

The oxlint autofix rewrites the expression but leaves the now-unused
node:url / node:path imports behind (which the already-enabled
no-unused-vars=error would then flag), so this commit also removes those
34 orphaned imports — trimming the named import where other names are
still used, deleting the line where it was the sole import.

Scope is build scripts + Node-env tests only (config/scripts, tools/
benchmarks, *.test.{ts,mjs}, vitest configs); zero shipped runtime code.
The native properties are exact equivalents (Node >= 20.11; repo is on
24), so behavior is unchanged.

Verified: oxlint 0 errors tree-wide (root + mobile), oxfmt clean,
typecheck (node+cli+web) + mobile tsc pass, root vitest 22825 passed /
0 failed, mobile vitest 1018 passed. Exercised the rewritten scripts
directly: build:relay (6 targets), ensure-native-runtime,
verify-macos-entitlements all run correctly with import.meta.dirname.
