Fourth and last of the stacked Phase 2 branches: #201 → #202 → #204 → this. Review it against feat/agent-vcs-reads, not master.

Closes #205.

What this does

wr-agent gains a generic exec service on the existing Service::Vcs envelope, discriminated from a read Request by a "kind":"exec" field so the read wire format is untouched: argv (executable constrained to a git/jj enum), cwd, stdin and a timeout in; exit code, stdout, stderr, timed_out and signaled out.

CLIVCSWriter's argv building, output parsing and failure classification are unmodified. Only the StatusCommandRunning conformer it spawns through changed — AgentCommandRunner, forwarding to the exec service instead of Process. RepositoryRouter.writer(for:) routes local writes through the same agent connection reads already use, falling back to a native CLIVCSWriter only when obtaining the writer fails (VCSError.backendVersion, a pre-upgrade agent), never mid-write.

The exec service deliberately never takes the JJ snapshot barrier: CLIVCSWriter's JJSnapshotGate already holds <shared>/.jj/workroom-vcs.lock for the whole gated write, and wr-agent's own SnapshotLock locks the identical file for read-side snapshots — taking it again would self-deadlock.

What the review changed, and why it matters for reviewing this

The first draft argued that because CLIVCSWriter is untouched, the two paths "classify identically by construction". That was false, and it is the most useful thing to know before reading the diff. A three-cycle review (6 specialists + 2 Claude adversarial passes + 3 Codex passes, one structured) found the same classifier reaching opposite verdicts on the two paths, because they fed it different input — which is harder to catch than two classifiers, since nothing looks out of sync.

Five P1s, all reproduced, all fixed in ed51faa:

	Defect	Fix
1	A descendant holding the child's pipe (ssh ControlPersist, a daemonising credential helper, gpg-agent from commit -S) wedged run_exec's unbounded join. That thread is the one dispatch spawned, so its Permit never dropped, one of 32 ACTIVE slots — shared with every read — leaked, and is_busy() stayed true so the daemon never idle-exited. 32 occurrences kill the VCS service until wr-agent is killed by hand.	drain_capped publishes into a shared sink; run_exec detaches the readers after a 2s deadline, mirroring StatusCommandRunner's own bounded drain.wait and its stated reasoning
2	Every transport failure became launchFailed, whose doc reserves that value for "nothing ran". There is no cancel message in the protocol, so a cancelled or disconnected push completes host-side and was reported as never having launched — inviting a retry that double-applies it	Split into neverRan and outcomeUnknown; new HostConnectionError.notDispatched keeps a local pool-full refusal on the honest side
3	Cancelling a gated write released the jj flock while wr-agent kept writing. JJSnapshotGate's "a started native operation retains this tail until its actual completion" held only by accident — a Process inside runBlocking cannot observe Swift cancellation, an agent round trip can	The gate shields its operation once it holds the flock
4	Non-network commands forwarded only PATH, so the child inherited GIT_AUTHOR_*/GIT_CONFIG_GLOBAL/HOME from whichever app launch first spawned the daemon — silently authoring commits under a stale identity	One StatusCommandRunner.childEnvironment for both paths; run_exec env_clear()s before applying it
5	A missing git/jj raised an Io error, so a missing tool was reported as a deleted workroom — the exact conflation launchFailed's doc warns about, mirrored	run_exec spawns /usr/bin/env <tool> exactly as native does, making 127/126 env's real exit codes

Two follow-on rounds caught regressions in those fixes, also fixed: env_clear() had dropped the GIT_DIR/GIT_WORK_TREE scrub (a commit requested in one repository landed in another and reported success), and the timeout SIGKILL fired after normal exits and could then be skipped entirely.

Note the blast radius. The GIT_DIR scrub now lives in childEnvironment, so the native path gains it too — it never had one, and was the unsafe side of that pair. JJSnapshotGate and HostConnectionManager also changed. All three are outside the files this branch originally touched; each is the root cause rather than the symptom.

The outcome-unknown taxonomy (f762d02, f05f64f)

P1 #2 above stopped the message lying, and left the button. An outcome-unknown write classified as .other, whose recovery in retryAction is a retry of the action that failed — so an honest "this may have completed" came with a Retry beside it. That was carried as a known gap; these two commits close it.

The distinction had nowhere to live, so it gets a value: CommandResult.outcomeUnknown, a sentinel exit code beside the existing launchFailed, and for the same reason. The old result was SIGTERM-shaped and therefore indistinguishable from a genuinely signaled git, which is why it fell into .other. That completes the partition every write classifier depends on — launchFailed asserts nothing ran, a real exit code asserts a known outcome, and this asserts neither. It is a state the native path cannot produce: a Process either runs or fails to launch, and either way the answer arrives.

VCSRemoteFailure.outcomeUnknown / VCSCommitFailure.outcomeUnknown carry it to the UI, classified ahead of every output check — the stderr is the transport's own description, so matching git's prose against it could only misfire.

The recovery rule is idempotence, not "never the failed verb". fetch and abortRebase are idempotent (a second git rebase --abort exits "No rebase in progress"), so they are offered back; push and pull are swapped for a fetch, whose ahead/behind is precisely the fact that resolves the doubt. A successful one clears lastFailure, so the tier is not a dead end.

A required adversarial pass (macapp/AGENTS.md rule 3) then found six defects in the surfaces that value reaches, none in the hunk that introduced it — fixed in f05f64f:

	Defect	Fix
1	The same bug, sibling surface. CommitSheet.isSpent covered only .landedThenFailed, so .failed(.outcomeUnknown) left Commit enabled beneath a notice saying to check the history first — one click from the second commit, on the taxonomy that had just added a case to name it	.outcomeUnknown becomes its own Phase, for .landedThenFailed's stated reason: the button is the hazard, not the wording. Not folded into it, which asserts the commit was recorded
2	.fetch was generalised from the push case. A lost abortRebase was answered with Fetch — which resolves nothing about a parked rebase, and, since perform allows an abort with no remote, replaced the doubt with an unrelated .noRemote	The idempotence rule above
3	The disk is not output. Returning the sentinel before the .pull + rebaseInProgress check discarded the only positive evidence available: no read path checks for a parked rebase, so the offered Fetch cleared lastFailure and restored an ordinary toolbar over a workroom parked mid-rebase	Asks the disk in the same order the timedOut branch does, accepting the same race for the same stated reason
4	The remedy was written for push ("if the push landed… push again") and rendered for every verb and for read failures — tier [13b] routes a read through the same describe/remedy pair. Telling someone whose rebase may be half-applied to push is wrong advice, not wrong wording	Verb-neutral copy
5	The dialog title and the spoken label both hardcoded "\(verb) failed" over a body saying it may have succeeded. For a VoiceOver user that sentence is the message	Both route through one headline
6	guard ita.ok else { return ita } returned the intent-to-add result to be classified as a commit ("The commit was sent…"), and skipped the index rollback — pre-existing, but lost contact is the one case where those entries may actually have landed, which is exactly the git stash breakage that rollback exists to prevent	The rollback is a local function both exits use; the staging failure is labelled as its own step

Also corrected: VCSCommitFailure.outcomeUnknown's doc and copy claimed the ref "could not be re-read", which commit() does not enforce (a ref that read back unchanged lands there too), and readRetryIsWorthwhile's comment called the new arm unreachable when tier [13b] makes it the live path.

The TODOS.md entry is marked fixed and the design doc's criterion 2 no longer records an exception.

Known gaps, tracked not hidden

The standing TODOS.md entry ("Agent-routed VCS writes: the findings the /review pass didn't fix") lists the rest: the unbounded child.wait() after SIGKILL, process-group vs process-tree kill, the writes: 8 pseudo-capability, the MAX_EXEC_STREAM / MAX_RESPONSE mismatch, the 1 MiB request ceiling, read/write pool sharing, and a capabilities-negotiation disconnect missing the agent respawn. None is silent data loss.

Design doc updated: the falsified claim is replaced with the three properties that actually produce parity, and Next Steps item 3 records the two questions this opens for Phase 3 (how a remote host resolves auth, since every forwarded value is a path into the client's filesystem; and that any transport carrying exec needs shell-grade peer auth — there is no code guard today).

Validation

• cargo test -p wr-agent — 168 pass, clippy clean
• make app-lint — strict, full tree, clean
• make app-test APP_TEST_FLAGS= (serial) — 2759 pass, 1 skipped, 0 failures
• New coverage: 6 Swift integration tests driving the bundled agent through the real client (git + jj commit, push/pull against a real bare remote, failure-classification parity, two write-capability fallback shapes), plus Rust tests for the drain bound, the 127 mapping, env replacement, and the snapshot-barrier non-contention property
• Outcome-unknown taxonomy: 6 further cases — the sentinel's precedence over output matching, the end-to-end no-retry path on both taxonomies, the idempotence rule per verb, the parked rebase on disk, the heading, and the verb-neutral remedy

Not run: XCUITest (no UI interaction flow added; CommitSheet's change is a disabled-state one).

Merge Risk: 🟡 Moderate · up to 466de

Routing writes through the agent introduces "outcome unknown" handling, but two paths still behave incorrectly. After a commit whose result is uncertain, the app can unstage files the commit already recorded. The next terminal commit would then delete those files. Temporary busy conditions are reported as "This workroom's folder is no longer there", with no way to retry. A hung agent is treated as a dead one, and the uncertain-commit notice is titled "failed". Fix the rollback and the refusal classification before merging.

Confidence Score: 3/5

The PR is not yet safe to merge because an uncertain intent-to-add step disables a commit that was never attempted, and timeout cleanup can SIGKILL an unrelated process after PID reuse.

Findings

1.  Staging Failure Blocks Commit ▶
2.  Stale PIDs Kill Processes ▶
3.  Unsent Writes Look Ambiguous ▶

Fix with agent prompt

### Issue 1
macapp/WorkroomApp/Core/VCSWriting.swift:1893-1898
If the intent-to-add request loses contact, this branch returns `CommandResult.outcomeUnknown` before the commit command at lines 1901–1903 is ever invoked. `classifyCommit` then reports that the commit may have been written, and `CommitSheet` disables the Commit button as spent. A transient staging disconnect therefore prevents the user from submitting a commit that was never attempted and gives the wrong recovery guidance. The rollback also uses the same runner, so it cannot reliably remove intent-to-add entries when that connection has already failed.

### Issue 2
vcs/crates/wr-agent/src/vcs.rs:432-435
`kill_recorded` saves only numeric descendant PIDs at SIGTERM and blindly sends SIGKILL roughly two seconds later. If a descendant exits during that grace period and its PID is reused, this can kill an unrelated process. This crate already handles the same risk elsewhere by recording process start times and checking `Descendant.is_running()` before signaling, but this new termination path skips that identity check.

### Issue 3
macapp/WorkroomApp/Core/AgentVCSConnection.swift:247-248
When `closed` is already true, this branch returns `connectionLost` before scheduling any socket write. During the race between `AgentVCSConnection.fail()` closing the connection and `HostConnectionManager` invalidating its lease, a write can pass the lease check and reach this branch. `AgentCommandRunner` then maps the error to `outcomeUnknown`, so the UI says the operation may have completed even though no request byte was sent. This creates unnecessary uncertainty and the wrong recovery behavior for a definitively unstarted write.

For each issue above, determine whether it is valid and should be fixed. If so, fix it directly.

Summary

This PR routes local Git and Jujutsu writes through wr-agent’s new versioned exec service while preserving the existing Swift-side command construction and classification.

• Adds bounded command execution, output capture, timeout escalation, request chunking, and capability negotiation.
• Routes local writers through the shared host connection with native fallback for older agents.
• Adds outcome-unknown failure handling and corresponding commit/sync presentation.
• Extends integration and protocol coverage for Git/JJ commits, remote operations, environment parity, chunking, and process cleanup.
• Two blocking correctness issues remain in staging-failure classification and stale-PID termination.

🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

Do not roll back intent-to-add after a commit whose outcome is unknown or that was killed.

rollBackIntentToAdd() runs for every !result.ok. That includes CommandResult.outcomeUnknown and a timedOut/signaled commit. In both cases the commit can already be written. commit() handles exactly this case with .committedThenFailed and the .outcomeUnknown copy.

If the commit landed, the newly added files are in HEAD. git rm --cached --ignore-unmatch then removes them from the index. git status shows them as staged deletions and as untracked files. A later git commit from the terminal deletes them from the repository. The user is told "Do not commit again", while the index now holds a pending deletion they did not make.

Roll back only when the command definitively failed. The intent-to-add rollback at line 1889 is correct as it is, because no commit ran on that path.

🐛 Proposed fix

-    if !result.ok { await rollBackIntentToAdd() }
+    // Only a definitive failure. An unknown outcome or a killed commit may already have recorded
+    // these paths; `rm --cached` on them would stage their deletion.
+    let definitelyFailed =
+      !result.ok && result.exitCode != CommandResult.outcomeUnknown && !result.timedOut
