Neil d5750648c2 fix(runtime): route runtime Git by resolved execution host, not repo connectionId (#18307)
`RuntimeGitTarget` carried `connectionId?: string` and no host id, so `undefined`
spelled three different answers at once — "runtime: host", "unresolved", and
"genuinely local". Its sole resolver read `store.getRepo(worktree.repoId)?.connectionId`
and never looked at `worktree.hostId`, which outranks every repo row, so one
arbitrarily chosen row decided the execution host for 36 downstream dispatches.

The target now carries `executionHostId: ExecutionHostId` (never null, never
optional), resolved through the shared rule that landed with #17909/#17919 and
dispatched through the host-keyed routes from #18296. Dispatch sites call
`requireRuntimeGitProvider`, where `null` means exactly one thing: the host is
`local` and the command runs here as free functions.

Four answers that used to collapse into one:

- `ssh:x` with a rival row on `ssh:y` — routes to x. Previously the first row won,
  which is the reproduced cross-host leak.
- `local` with a surviving `connectionId` — a row contradicting itself; no SSH
  connection is handed out.
- `runtime:<env>` — throws `ExecutionHostNotDispatchableError`. Its repo row's
  connection names a target in the *server's* namespace; dialling it here reaches a
  same-named target on this client.
- rival rows disagreeing with no worktree host — `worktree_execution_host_unresolved`,
  matching the launch path rather than guessing a row.

An unreachable SSH host still throws `SSH_GIT_PROVIDER_UNAVAILABLE_MESSAGE`; loss of
contact is never evidence of locality (docs/reference/ssh-execution-boundary.md).

`resolveWorktreeLaunchHost` keeps its exact signature and now delegates to
`resolveWorktreeHostRouting`, the same resolution answering "which host is this on"
rather than "what may this client dial" — the git target needs the first question
because `local` and `runtime:` are two different non-SSH answers.

No wire change: `RuntimeGitTarget` is main-process internal, and the SSH and local
model-discovery host keys are byte-identical to before.

`RuntimeFileTarget` has the same defect in ~30 filesystem dispatches and is
deliberately left for a follow-up.

Neil b4ba3e97ff perf(worktree): defer fork-PR remote creation from create-time to first use (#17922)
* perf(worktree): defer fork-PR remote creation from create-time to first use

Fork-PR review worktrees eagerly ran `git remote add` + `git fetch` for the
contributor's fork (and pinned branch.<x>.remote) at create time, even for a
read-only review. That grows remote count unboundedly with review volume and
pays a network fetch nobody asked for yet.

Defer prepareWorktreePushTarget(Ssh) and the --set-upstream-to configure step
at create time (local + SSH, IPC + runtime create paths); persist the
pushTarget metadata untouched. Materialize the remote on demand the first
time push/pull/fetch/fast-forward actually needs it, via two shared
functions (materializeWorktreePushTargetRemote(Ssh)) reused across the
legacy IPC handlers and the RPC runtime sync commands. A cheap
`remote get-url <name>` probe keeps steady-state calls down to one extra
subprocess once materialized, instead of repeating the O(remotes) scan.

Add repo-local `remote.<name>.orca-created` config provenance, written when
the remote is added, so cleanup can recognize ownership of a remote that was
lazily materialized (and therefore never round-tripped through the store's
`remoteCreated` flag).

Refs #17828

* perf(worktree): materialize a deferred fork-PR remote on terminal spawn

An agent running raw git in a freshly opened fork-PR review terminal has no
usable upstream until an Orca-driven sync happens -- "sync through Orca
first" isn't available mid-task, and git pull/log @{u}.. hard-fail without
one (verified against real git). Fire the same on-demand materialization
used by push/pull/fetch/fast-forward from the single terminal-spawn
resolver (resolveTerminalWorkspaceLaunchTarget), fire-and-forget, so a
newly opened terminal gets a working upstream without blocking spawn.

* fix(worktree): retest deferred fork-remote CI failures, fix SSH provenance-marker RPC

Rewrites the 5 CI failures on the deferred fork-remote change (#17828) as
evidence, not fixtures: the SSH relay-upgrade/rollback/sibling-ownership
tests move to materializeWorktreePushTargetRemoteSsh, where that
unchanged logic now actually runs (create defers it to first sync).

While writing a stricter test that routes its mock exec through the
relay's real validateGitExecArgs, found that the SSH provenance-marker
write (`git config remote.<name>.orca-created true`) was unconditionally
rejected by the relay's generic git.exec (it blocks all non-read-only
config writes) -- a real bug that would break every SSH fork-remote
materialization against a live relay. Fixes it with a narrow
git.markRemoteOrcaCreated RPC, mirroring renameCurrentBranch, with a
graceful no-op fallback for relays that predate it.

* fix(worktree): scope post-#17887 test assertions past narrow-refspec config calls

Rebasing onto #17887's narrow-refspec `remote add` broke two broad `['config']`
call-filters into false positives/negatives, and the local materialize test still
asserted the pre-#17887 wide `remote add`/fetch-refspec forms.

* fix(worktree): restructure upstream restore, persist provenance, widen short-circuit refspec (#17828 review)

- Move upstream restoration to the materializer level so it runs on both the
  remoteAlreadyMatchesUrl short-circuit and the full-prepare path, not just
  buried inside prepare*.
- Persist {remoteCreated, remoteName} to the store on materialize so #17842's
  orphan sweep can see a lazily-created remote, including via desktop IPC,
  terminal-spawn, and the RPC host-callback paths.
- Widen the refspec on the local short-circuit path too (SSH's bare `remote
  add` refspec gap remains a documented, pre-existing limitation).
- Fetch the branch's tracking ref before restoring upstream when the
  short-circuit widens onto a *new* branch on an already-existing remote --
  a bare refspec-config widen never itself imports anything, so
  `branch --set-upstream-to` was hard-failing for a sibling worktree's first
  materialize (found via a real-git fixture, not just mocked unit tests).
  Skipped when the ref already exists so the common repeat-call case stays a
  local-only probe with no network round-trip.

* fix(worktree): merge duplicate shared/worktree/types import

oxlint --deny-warnings flags the split import as no-duplicates; full pnpm lint
was failing on it after the #17828 review restructuring.

* fix(worktree): scope the deferred fetch timeout to fetch calls, retarget stale create-time assertions

CI on the previous push failed 3 shards, all argument-shape mismatches:

- worktrees-wsl-runtime-routing.test.ts: the "restructure upstream restore" commit
  wrapped every call `prepareWorktreePushTarget` makes (remote, remote add, config,
  fetch) with DEFERRED_PUSH_TARGET_FETCH_TIMEOUT_MS, not just the network fetch. Local
  git subprocesses never need a timeout; scope it to `args[0] === 'fetch'` only,
  matching the short-circuit path's existing pattern. Updated the test to expect the
  timeout on the fetch call specifically (point 5 legitimately adds it there), while
  every other call stays untimed.

- worktrees-create-metadata-persistence.test.ts (2 tests): stale from before this
  session -- create no longer mints a fork remote at all (#17828 deferred that to
  first sync), so asserting `remote add`/`fetch`/`remoteCreated: true` at create time
  no longer matches reality. Retargeted both tests to assert the deferred contract
  (no remote add at create, pushTarget persisted unmaterialized); minting itself
  stays covered by worktree-remote-push-target-materialization.test.ts and
  worktree-push-target-setup.test.ts.

Re-verified all 5 fixture points (mint upstream, store persistence, single-flight,
short-circuit refspec widen + fetch-missing-ref for local and SSH, finite timeout)
against a real git fixture after this fix -- all still pass.

* fix(worktree): hook pty:spawn into deferred push-target materialization (#17828)

triggerTerminalSpawnPushTargetMaterialization only fired for agent/background/
mobile terminals; the desktop GUI's own pty:spawn path (new tab, split,
reattach) never materialized a deferred fork-PR remote before raw git
commands could run there. Add a small wrapper that resolves the worktree's
push target and owning repo from args.worktreeId via the store, and
fire-and-forget delegates to the existing materializer, wired as the first
statement of runPtyIpcSpawn. Degrades silently (optional chaining + catch)
so a partial/fake Store in existing spawn tests can't turn this into a
spawn-blocking throw.

* test(worktree): retarget stale editor-remote-branch assertions for worktreeId threading

runtime-git-sync-client's local-path fetch/pull/fastForward/push calls now
forward context.worktreeId (needed by the main-process handlers to key
deferred push-target materialization). Update the 17 call-site mocks across
15 tests in editor-remote-branch-actions.test.ts to expect worktreeId: 'wt-1',
matching the already-correct source behavior -- no assertion was loosened.

* fix(worktree): give a materialize joiner its own branch wiring

The materialize single flight is keyed on the remote, but everything after
the remote add is per-branch. A sibling worktree joining an in-flight mint
for a different branch received the minter's target and skipped its own
refspec widen, tracking-ref fetch, and upstream link, so its branch ended
with no upstream at all.

Wait for the remote, then run the per-branch work against the joiner's own
target -- the same path the already-exists short-circuit takes, now shared
rather than duplicated. Adopting a remote a sibling minted also stamps
ownership, so removing the minter cannot strand the survivor's metadata
outside the orphan sweep's reach.

* fix(worktree): stop a failed mint from leaving a config-only fork remote

Review of the joiner fix found it made things worse in three ways.

Swallowing the mint's rejection let a joiner adopt a remote the rollback
had already removed, writing remote.<name>.fetch with no URL. Verified on
real git: that ghost section breaks `git fetch --all`, forces every later
mint to a `-2` name, and cannot be removed by `git remote remove`.
Propagate instead; the in-flight map is already cleared, so a retry
re-mints.

The SSH twin still returned the minter's target to a joiner, so the
original per-branch bug survived there. It now adopts against its own
target through a twin helper.

The ownership stamp was unreachable: it required both a store and a repo
id, and no caller passes both. Derive the repo id from the worktree id.

Adopters also write remote config, and concurrent `git config --add` has
no lock retry -- 135 of 160 writes failed at 8-way concurrency, and equal
values duplicate the refspec. Chain adoptions per remote.

Brennan BensonandMerge Sim b5a85890ac perf(git): bound git subprocess execution with an atomic admission scheduler (#16874)
* perf(git): bound git subprocess execution with an atomic admission scheduler

Field traces (#16038, #11363) show Windows freeze storms driven by unbounded
concurrent git children (12+ at once, 50-65s status convoys for 25+ minutes).
Admit every main-process git child against atomic per-budget base+headroom
counters (general / network / per-route), with reserved interactive capacity,
ordering-only aging, close-bound permit release, a 120s fail-safe read timeout
that feeds scheduler backoff, tier plumbing through every option carrier, and
coalesced+jittered visibility pollers. Killswitch: ORCA_GIT_ADMISSION_DISABLED=1.

Storm harness A/B: max concurrent children 65 -> 6, interactive p95 791ms -> 88ms;
output-parity battery byte-identical with admission on vs off.

* test(git): run the admission output-parity battery on every platform

Parity needs real git, not the storm harness's PATH stub, so it must not share
that file's POSIX gate - Windows is the platform where parity evidence matters.

* fix(git): preserve interactive admission invariants

* perf(git): keep admission queue drains linear

* fix(git): close final admission gaps

* perf(git): bound eligible route selection

* fix(merge): remove unrelated stale snapshot changes

* fix(git): preserve refresh lifecycle authority

* test(git): align admission lifetime contracts

* fix(git): harden admission across runtime paths

* fix(git): restore freshness for bulk status reads

* test(git): repoint delete-dialog source pins after admission plumbing

The hydration effect now orders its targets through
orderDeleteWorktreeStatusHydrationTargets and passes includeLineStats
alongside the abort signal, so both literal anchors stopped matching.
The invariants are unchanged and still pinned: dropping the signal, the
main-worktree/folder filter, or getState-instead-of-subscribe each
still reddens this test.

* Fix git admission tier propagation and lock ordering

Decode optional Git status tiers permissively and default runtime RPC status reads to the status lane while preserving renderer caller intent.

Acquire the FETCH_HEAD mutex before atomic admission so same-repository fetch waiters hold no global or route permits.

Preserve automatic pull-request refresh reasons, keep explicit hosted-review refreshes interactive, remove the dead candidate tier, and keep relay scheduling unchanged.

Use tier-aware status lease keys because a shared lease cannot be safely promoted after its admission request is queued or granted.

* test: align expectations with admission plumbing

* refactor(child-process): move the process contract types to process-spec

run-process.ts crossed its line cap after gaining the termination observer;
the public types and defaults move out with re-exports so no caller changes.

* chore: restore pnpm-lock.yaml to main (unintended local drift)
