📝 Walkthrough

Walkthrough

The live-kernel tests now cover an agent CLI that exits with status 9. The test verifies the completed step state, failed run status, and worker_error journal reason.

Changes

Agent worker failure handling

Layer / File(s)	Summary
Failure-path integration test sdk/tests/live-kernel.test.ts	Runs a deliberately failing agent CLI. Verifies the run fails, the execute step completes, and the journal records worker_error.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to 32751

This change only adds a localized end-to-end failure-path test, and no actionable merge-blocking risk remains after normal checks and review.

Poem

A rabbit watched the worker run
The failing command stopped at nine
The journal marked the error clear
The step completed without fear
And failed runs now leave a sign

Maintainability review — PR #80 (sdk/tests/live-kernel.test.ts +37 lines)

The new test mirrors the shape of the preceding happy-path SDK-worker test (lines 206-239), which is the right structural choice: a future reader can diff the two blocks and see exactly what the failure path changes. Setup, teardown, and helpers all reuse the file's existing conventions (temporaryDirectory, waitForStep, completionReasons, afterEach global cleanup), so no new implicit contracts are introduced at the fixture layer.

Concerns (non-blocking):

1. Undocumented divergence between worker_error and step_failed. The test at line 273-276 asserts completionReasons(...) === ['worker_error'] for an agent CLI exiting nonzero, while the deterministic-step failure at line 116-117 asserts step_failed for the analogous case. That divergence is real product contract — but a stranger reading only this test in six months has no way to know it's intentional versus a mislabel someone was pinning. Recommend a one-line comment ("nonzero agent CLI ⇒ worker_error, distinct from deterministic step_failed") or a RFC §… pointer. Without it, someone unifying the reasons breaks the test and cannot tell whether the assertion or the code is wrong.

2. stderr is written but never observed. The fixture writes printf 'agent failed' >&2 (line 243) but no assertion inspects whether the kernel surfaces that diagnostic anywhere in the journal. If the kernel silently drops stderr on agent failure, this test still passes — so the test does not fail if that behavior regresses. Either drop the stderr write (it's misleading, implying a checked contract) or add an assertion that the failure diagnostic shows up in the journal payload.

3. state: 'done' co-existing with status: 'failed' is subtle. waitForStep(..., 'done') succeeds, then runGet returns status: 'failed'. That's a real invariant (terminal step state ≠ success), but it's the second time a reader has to internalize "done means terminal, not successful" and it isn't explained here or at line 234. A one-liner would earn its keep.

Notes:

• If waitForStep or journalRead throws, worker.close() on line 276 never runs. The sibling test has the same shape (line 238), so this is consistency, not a regression — the afterEach clients sweep covers the client but not the AgentWorker listener. Worth a shared cleanup helper someday, not in this PR.
• Exit code 9 is arbitrary and not part of any asserted contract; fine, but if future readers wonder, that's why.

The test adds real coverage for the SDK worker's nonzero-exit path and pins two journal-visible facts (status: 'failed', completionReason: 'worker_error'). The chain — fixture → nonzero exit → journal reason → run status — is legible without external context. The concerns above are meaningful for a six-month reader but do not block correctness of the assertion.

Blocker

• Commit 327512a does not truthfully describe the change. Its subject, drive: cloud run c3defe1b, says nothing about the nonzero-exit regression added at sdk/tests/live-kernel.test.ts:241-275. Worse, its body claims “Verification and adversarial review ran in-run; see ops/reviews/ in the diff,” but the diff contains only this test file and no review transcript or captured verification output. This repeats the delivery/evidence drift recorded in ops/DRIVE-LOG.md:247-257 and ops/DRIVE-LOG.md:379-394, as well as the identical blocker raised on PR drive: cloud run a0e0715c #79. Amend the subject to describe the regression test and remove or persist the unsupported evidence claim.

Concerns

• The fixture deliberately writes stderr and exits 9 at sdk/tests/live-kernel.test.ts:245, but the assertions at sdk/tests/live-kernel.test.ts:268-274 verify neither value. Any path producing worker_error, including failure to spawn the CLI, could satisfy the test. This repeats PR drive: cloud run a0e0715c #79’s recorded weak-assertion concern. Assert the recorded exit_code: 9 and stderr, or simplify the fixture so it does not imply those values are pinned.
• Compared with PR drive: cloud run a0e0715c #79’s earlier version, this revision removes the explicit run.completed assertion for run-level completionReason: step_failed. The remaining failed status plus step-level worker_error is useful, but weaker than the prior candidate’s direct proof of RFC-0001’s closed typed-failure chain.

Notes

• No merged behavior appears to have been deliberately removed and reintroduced.
• The intended behavior itself agrees with RFC-0001: execution remains SDK-side, the journal protocol is the boundary, and a nonzero agent CLI exit fails closed with worker_error.

Structure review — PR #80

Scope: a single test addition to sdk/tests/live-kernel.test.ts (+37 lines, inserted before the "late-attaching worker" case). It pins that a nonzero agent CLI exit surfaces as status: 'failed' with completionReason: 'worker_error'.

Boundaries — clean. The test is placed exactly where it belongs: it exercises the SDK worker's exit-code→reason translation (sdk/src/worker.ts:56) against a live relayflowd, asserting through the journal (client.runGet / journalRead). The kernel never learns about CLI exit codes — the SDK maps an exit_code !== 0 to the declared worker_error kind, which already exists in the closed vocabulary (protocol.ts:178, matching the kernel's WorkerError variant called out in prior structure reviews). This is helper-over-primitive in the correct direction: no new kernel step verb or CompletionReason variant is introduced. RFC covenant 2's typed-failure discipline is upheld, not widened.

Coupling — low. The new case reuses existing fixtures wholesale (temporaryDirectory, startDaemon, connectClient, waitForStep, compileYaml/toKernelSpec, completionReasons, journalRead). It mirrors the adjacent "runs an agent CLI end to end" case (lines 206–239) in shape — same inline #!/bin/sh CLI, same pins, same worker.close(). No duplicated setup or speculative abstraction.

Concerns (non-blocking):

• File size. live-kernel.test.ts is already 693 lines and this PR pushes it to ~730. AGENTS.md rule 1 flags "any file approaching 500 lines" as a design smell. Test files reasonably run long, but this file is now 1.4× the threshold with no split. A note to consider carving the SDK-worker cases (around 206–344) into their own spec before the file accretes further.
• Notes (trivial). The CLI writes agent failed to stderr but the test asserts nothing about that output — it only checks exit code → worker_error. The >&2 printf is decorative rather than probed. Fine as-is, but if stderr capture were the intent it's unverified. Also worth observing the test asserts status: 'failed' on the run, not just worker_error on the step — a slightly stronger claim than the title suggests, and correct.

No product logic reaches the kernel; no primitive was added instead of a helper; no file grows past its purpose. The change is a well-shaped, correctly-layered regression pin.
