📝 Walkthrough

Walkthrough

The live-kernel tests now cover an agent CLI that exits with status 7. A polling helper waits for the run to fail. Assertions verify worker completion, journal metadata, and the worker_error completion reason.

Changes

Live-kernel failure handling

Layer / File(s)	Summary
Agent failure-state validation sdk/tests/live-kernel.test.ts	Added a polling helper and an end-to-end test for a nonzero agent CLI exit. The test verifies the failed run status, step_failed journal entry, completed agent step, and worker_error reason.

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

Merge Risk: ⚪ Minimal · up to abf12

This PR only adds localized end-to-end test coverage, and no actionable merge-blocking risk remains after normal checks and review.

Poem

A rabbit watched the worker run,
Then saw exit code seven come.
The journal marked the failed step,
The polling helper made its check.
“worker_error!” the carrots cheer,
The run state settled bright and clear.

Maintainability review — PR #79 (AgentWorkforce/flows)

Concerns

1. sdk/tests/live-kernel.test.ts:275 — test pins the failure surface but not that it originated from the CLI. The assertions verify completionReason: 'step_failed' and worker_error, but nothing observes that the child process actually ran or that its stderr (printf failure) reached the journal. If a regression made the worker return worker_error without ever exec'ing the CLI (e.g. a spawn precondition check that always fired), this test would still pass. The printf failure >&2 at line 244 exists to signal the write happened, but nothing reads it — either drop the stderr write to make intent honest, or add an assertion that the recorded error carries the child's stderr and/or exit code 7 (currently the choice of 7 is arbitrary and unverified — swapping it for 0 would be the only way the test fails on the CLI-side, not the worker side).

2. Undocumented dependencies on helpers not in the diff (completionReasons, journalType). The test at line 279 calls completionReasons(entries, 'execute') and at line 277 calls journalType(entry). Neither is shown in the diff, so a future editor reading this test in isolation must go hunting to understand the contract being asserted. Consider a one-line comment naming what shape they return, or inline the extraction so the test is self-describing.

3. waitForRun duplicates waitForStep shape (lines 694–703 vs. the existing waitForStep). Same 5000ms deadline, 20ms poll, same error phrasing. Not a blocker at N=2, but the next waitForX helper should push someone to fold these into waitFor(label, predicate, timeout). Flag now so it isn't three copies before anyone notices.

4. Executable-bit fragility in the fixture (line 244–245). chmodSync(cli, 0o755) immediately after writeFileSync. Recent commit 7331e12 exists specifically because fixture +x bits get lost on some paths. Writing directly to a fresh temporaryDirectory is probably safe, but if this test ever gets copied into a checked-in fixture, the bit will vanish. A one-line comment ("chmod required — filesystem may strip +x on npm pack/publish paths") would inoculate the next copy-paster.

Notes

• cli: ${JSON.stringify(cli)} (line 267) is the right escape for embedding a path into inline YAML; good instinct.
• The test aligns with AGENTS.md §4 "fail closed" — pinning that a nonzero exit propagates through both the step-level worker_error and the run-level step_failed is exactly the kind of contract that should be locked down.
• worker.close() is called; consistent with sibling tests. No explicit daemon teardown, but that mirrors the file's convention.
• Test name is precise and grep-friendly.

No blockers. The weak-assertion concern (#1) is the one worth acting on before merge — either strengthen the assertions to prove the CLI ran, or delete the misleading printf failure >&2.

REVIEW_PASSED

history lens — FAIL

Blocker

• The commit message does not truthfully describe or substantiate the diff. Its headline is only drive: cloud run a0e0715c, while the sole change is the nonzero-agent-exit regression at sdk/tests/live-kernel.test.ts:241-280. More seriously, the body says “Verification and adversarial review ran in-run; see ops/reviews/ in the diff,” but the diff contains only sdk/tests/live-kernel.test.ts; no review transcript or literal verification output exists. This repeats the commit-title/evidence drift recorded in ops/DRIVE-LOG.md:249-251 and ops/DRIVE-LOG.md:380-394, and violates AGENTS.md’s captured-evidence rule. Amend the subject to describe the regression test and remove or persist the unsupported verification claim.

Concerns

• None in the test behavior itself. The polling helper at sdk/tests/live-kernel.test.ts:694-702 follows the suite’s established asynchronous pattern.

Notes

• The test closes a genuine historical coverage gap: ops/NEXT.md:53-59 explicitly required reporting nonzero CLI exits through step.complete, while PR drive: cloud run 88aaba35 #53’s merged live test pinned only successful execution.
• Assertions at sdk/tests/live-kernel.test.ts:269-278 correctly preserve RFC-0001’s settled journal boundary and typed-failure decisions: the worker reports worker_error, the step terminates, and the run records step_failed.
• Full-history search found no earlier removal of this test or helper, so this does not reintroduce deliberately removed behavior.

Structure review — PR #79

The change is a test-only addition to sdk/tests/live-kernel.test.ts. No production code changes, no kernel edits, no new primitive.

Vocabulary discipline — correct. The new case pins a declared completionReason: a nonzero agent CLI exit surfaces as worker_error (waitForRun/completionReasons assertions in the diff, lines ~252-267 of the merged file). worker_error is already part of the closed kernel vocabulary (kernel/relayflowd/src/engine/DESIGN.md:65, sdk/src/protocol.ts:178), and the run-level terminal step_failed + failed_step_id matches the existing run.completed shape exercised at lines 122-126. This is fail-closed (a nonzero exit is not silently "succeeded") and carries a completionReason, satisfying AGENTS.md §4 and RFC Covenant 2. The test also exercises the SDK→kernel boundary correctly: worker.ts:56 maps exit code to worker_error, so the kernel never sees raw stack traces — good, the journal protocol remains the boundary (§2.1, §2.3).

Concern — file size. The file is now ~693 lines, past the 500-line "design smell" threshold in AGENTS.md §1. It already hosts three distinct describe blocks (CLI, wire conformance, surface resume) plus a large shared-helper section. This PR nudges it further over. Not a defect introduced by this diff, but worth flagging as the next split candidate.

Concern — helper duplication. The new waitForRun (diff +31-41) re-implements the same poll-until-deadline loop already present in waitForStep and waitForActiveRun, each with its own inline 5_000 deadline and delay(20). Three near-identical waiters is accumulated duplication; a single waitUntil predicate helper would collapse all three.

Note — Promise<unknown>. waitForRun returns Promise<unknown>, forcing the caller into toMatchObject/assertions rather than a typed RunStatus. Consistent with waitForStep, so not a blocker, but it erases the run shape at the helper boundary.

Notes (not issues): the new test reuses compileYaml/toKernelSpec and the AgentWorker attach pattern faithfully; worker.close() is present. It pins behavior that is genuinely deterministic (exit code → completionReason), so it belongs in the live-kernel suite per AGENTS.md §5.

Nothing here puts product logic in the kernel, adds a primitive instead of a helper, or reaches around the journal.
