maintainability lens — PASS

Maintainability review — PR #111 (sdk/tests/live-kernel.test.ts)

Concerns

C1. Shell interpolation via JSON.stringify is subtle (line 210).

`#!/bin/sh\nprintf '%s' "$1" > ${JSON.stringify(marker)}\n`

JSON.stringify produces a double-quoted string that usually round-trips through /bin/sh — but shell double-quotes and JSON encoding are different grammars. A path containing $, backticks, or ! (or a \n if temporaryDirectory ever handed one back) would be interpreted by the shell, not treated literally. Today's tmp paths avoid this; the invariant is nowhere stated. A stranger touching this in six months could reasonably reach for a path with a dollar sign in a fixture and get a bewildering failure. Prefer passing the marker path via an env var (MARKER=… /bin/sh -c 'printf … > "$MARKER"') or a heredoc, or leave a one-line comment nailing the assumption.

C2. The failure test pins status: 'parked' + state: 'done' with no explanation (lines 271–281).
A future reader will ask: "the agent CLI exited 7 — why is the run parked and the step done?" The answer lives in maxIterations: 1 (magic number, unexplained) plus kernel semantics that a step whose only iteration errored still transitions to done with completionReason: worker_error. That's a lot of implicit contract riding on the test. One line — // maxIterations: 1 → single failed attempt exhausts the budget; step lands done/worker_error, run parks — would save the next debugger a git-blame trip.

C3. Asymmetric 10 s timeout on the failure test only (line 282).
The success test uses the default; this one gets 10_000. No comment on why. Either the failure path is expected to be slower (say so) or this is defensive padding that will silently mask a regression. Pick one.

C4. Failure test asserts only the completion reason (line 279).
printf failed >&2\nexit 7 — the stderr content is dropped, the exit code is not observed in the journal assertion, and no artifact is checked. If a future refactor collapsed worker_error into a generic error reason, or forgot to plumb exit code into the journal payload, this test would still pass on the parts it does check. The test's name promises coverage of "the kernel failure path"; the assertion covers one string. Consider also asserting that some evidence of the nonzero exit (stderr snippet, exit code, or attempt count) reaches the journal payload.

Notes

N1. Happy-path marker assertion (line 239) is a real upgrade — the previous test would pass even if the CLI shim never ran. Good change. Minor: readFileSync(marker, 'utf8') will throw ENOENT with a generic message if the CLI didn't fire; wrapping with expect(existsSync(marker), 'agent CLI did not run').toBe(true) first would give the six-months-later reader the diagnosis for free.

N2. waitForStep last-observed dump (lines 688–697) is unambiguously good — this is exactly the kind of "why did my test time out" affordance the suite has been missing. Fine as-is.

N3. Duplication between the two agent tests (setup: tmpdir → cli → chmod → daemon → client → hello → AgentWorker → attach) is at two copies. Below the abstraction threshold today; worth watching if a third arrives.

None of the above are blockers — the tests are correct, add real coverage, and the helper improvement is a net win. The concerns are about making the why legible so a stranger in six months can change adjacent behavior safely.

history lens — FAIL

Blocker — untruthful commit message. Commit 43fb5c75 states: “Verification and adversarial review ran in-run; see ops/reviews/ in the diff.” The PR contains exactly one changed file, sdk/tests/live-kernel.test.ts; no ops/reviews/ evidence is present. This is a concrete false claim about files touched and evidence supplied, triggering rejection criterion 3.

Concerns — non-blocking. ops/NEXT.md still describes the broader agent-worker implementation package, while this PR only strengthens tests. Per the lens instructions, that stale drive-loop brief is follow-up bookkeeping, not a correctness blocker.

Notes. No historical regression or new RFC contradiction was found. The execution marker and assertion in sdk/tests/live-kernel.test.ts (diff lines 207–240) prevent a false-positive test where the step completes without proving the declared CLI ran. The nonzero-exit coverage (diff lines 243–278) verifies a typed worker_error completion reason, aligning with RFC-0001’s typed-failure covenant and settled decision 11’s completion/evidence split. The timeout diagnostic change (diff lines 685–695) only exposes the last observed state. These changes harden previously intended behavior rather than reintroducing a DRIVE-LOG mistake.

Structure review — PR #111

Scope. Test-only diff in sdk/tests/live-kernel.test.ts; no kernel/, SDK source, or protocol changes. Nothing here touches the RFC-0001 boundary, adds a primitive, or moves product logic into the kernel. On the structural axes this lens owns, the change is clean.

What it does well

• The new failure test (live-kernel.test.ts:243-280 in the diff) pins the fail-closed path — nonzero agent exit → worker_error — directly against the completionReason discipline (RFC-0001 Covenant 2, Appendix A.6). This is exactly the "typed failure, never a raw error" invariant the RFC demands, and it reuses the existing completionReasons helper rather than inlining a new extraction path.
• The first test's change (lines 210-239) replaces a stdout-echo assertion with a filesystem marker that captures the exact $1 instruction, strengthening the "instruction actually reaches the agent CLI" claim without growing the file's responsibility.

Concerns (non-blocking)

• expect(completed.status).toBe('parked') in the failure test couples the assertion to the run status (parked) in addition to the step-level done + worker_error. The wording invites a future change where a failed agent run surfaces a different terminal status (failed vs parked), and this test would over-constrain the shape. The step-level completionReasons([...]) assertion is the durable contract; the status line is surface. Worth a comment or a looser assertion.
• Hardcoded literal 'worker_error' is fine here — it matches the suite's existing style of asserting literal completionReason strings — but note it only pins the string, not membership in a declared closed taxonomy. Acceptable for a live-kernel pin.

Notes

• waitForStep observability improvement (observed capture, richer throw) is a pure diagnostic enhancement and correct: fail-closed testing needs the failure to be legible, not silent.
• File is at 693 lines but is a single-purpose integration suite; the added cases fit its purpose and don't approach the 500-line-per-module smell AGENTS.md warns about for modules.

No blockers.
