maintainability lens — PASS

I've read AGENTS.md (fail-closed rule, single-purpose modules), the LEAD charter (never merge, hard rails), RFC-0001 §1–§3 (covenants, gate ladder), and diffed the runner against worker.ts, hn-poller.ts, and journal-client.ts.

Maintainability review — PR #90 (hn-monitor-runner)

Concerns

C1. FetchError classification has a real hole. hn-monitor-runner.ts:23,29-35 wraps only the fetcher call in FetchError. But pollHackerNewsOnce (see hn-poller.ts:61-67) also throws when the body isn't JSON or isn't an array — those errors bubble as plain Error and will TERMINATE the runner. That's a bad failure mode: HN returning HTML during an outage is exactly the "fetch-level flakiness" the brief says should be swallowed, but the runner will kill itself instead. A stranger reading run() at line 55 has no way to see this distinction. Either widen the classifier (isTransportOrParseError) or document explicitly in the runner what "fetch-level" means.

C2. Marker-class trick reads as clever, not clear. FetchError at hn-monitor-runner.ts:21 is not even an Error subclass — no name, no message, no stack. If it ever escapes (bug in some refactor), you get a naked {cause: ...} object thrown across process boundaries. Extend Error or use a Symbol tag. The constructor-time fetcher wrapping (lines 30-36) also hides the intent: someone will look at run() and wonder why catch (error) { if (!(error instanceof FetchError)) throw error } is there without tracing back through the constructor.

C3. fetchText at hn-monitor-runner.ts:75-79 duplicates defaultFetcher from hn-poller.ts:28-34. Two identical HN fetch implementations that must stay in sync. If HN adds auth headers or you change the "HN fetch failed" error message, you'll fix one and forget the other. Prefer exporting the default fetcher from hn-poller.ts and reusing it.

C4. worker.ts:41 comment names the what, not the why. "Protocol v0 has no worker-release verb; close only detaches this local worker." A maintainer reading this needs to know the consequence: the kernel still thinks the worker is registered until socket close. Without that, someone will add this.attached = false and think shutdown is complete. Say "kernel still holds the worker registration; it's released only when the socket closes."

C5. Test brittleness — listenerCount('step.dispatch') === 0 (hn-monitor-runner.test.ts:59, 96) is an internal-implementation-detail assertion masquerading as "worker was released." It passes whether or not the kernel registration leaked. This is exactly the kind of test that wouldn't fail if the behavior broke — which the lens brief calls out explicitly.

C6. Weak "attach before poll" assertion. Test at line 42 (expect(client.calls.slice(0, 2)).toEqual(['attach', 'submit'])) only proves attach appears somewhere before the second call. It does NOT prove attach completed before the first poll started — since workerAttach is async, a naive future refactor that fires attach and poll concurrently could still pass this test if attach happens to resolve first.

Notes

• spec: unknown in HnMonitorRunnerOptions (hn-monitor-runner.ts:9) — passes through untyped to the poller. Two tests use {} and { name: 'hn-monitor' } interchangeably. No schema, no runtime check. Acceptable for now given the scaffolding scope, but the type-erasure boundary should be flagged.
• waitForNextPoll (lines 81-89) reads clean and handles the abort race correctly.
• The five findings from PR drive: cloud run 87bb2f91 #83 are addressed in the letter of the brief. My concerns are new maintainability issues introduced by how the fixes were done, not regressions on the findings themselves.

No blockers — the fixes land the objective, but the fetch-error classification hole (C1) is one merge away from being a real production surprise. Address before the CLI wrapper lands in sub-PR C.

history lens — FAIL

Blocker

• The commit message is factually false about evidence: it says, “Verification and adversarial review ran in-run; see ops/reviews/ in the diff.” PR drive: cloud run 89d58fe0 #90 changes only five files—ops/NEXT.md, three SDK source files, and one test file—and adds no ops/reviews/** artifact. This repeats the DRIVE-LOG’s recorded evidence-loss/false-pointer failure class and violates the repository rule that verification claims include literal commands and captured output. The diff’s own work-package contract requires those outputs (ops/NEXT.md:63-69), but none are delivered. I am not claiming the checks did not run; the claim that their evidence is “in the diff” is demonstrably untrue.

Concerns

• The scaffolding deferrals are clearly documented in ops/NEXT.md:3-9 and ops/NEXT.md:67-79, but not in the commit message or PR body as requested. This is delivery hygiene, not an additional blocker under this lens.
• AgentWorker.close() still leaves the kernel registration intact and merely documents that limitation (sdk/src/worker.ts:41-44). This is an explicit, permitted deferral rather than a regression.

Notes

• I found no new contradiction with a settled RFC-0001 decision. The runner stays SDK-side, communicates through JournalClient, distinguishes fetch failures from journal failures (sdk/src/hn-monitor-runner.ts:38-66), and uses opt-in cancellation.
• The new tests cover continuation after fetch failure and termination after journal rejection (sdk/tests/hn-monitor-runner.test.ts:65-98), addressing the substantive PR drive: cloud run 87bb2f91 #83 history called out in the brief.

Structure review — PR #90 (hn-monitor-runner scaffolding)

Boundary is respected. No kernel changes; the runner is SDK-side, and hn-poller.ts:1-15 already documents why HN logic must not live in kernel/. The runner composes existing primitives (JournalClient, AgentWorker, pollHackerNewsOnce) rather than reaching around them — correctly a helper composition, not a new primitive. No workerRelease verb was added (finding #2 option B), so protocol.ts stays closed; worker.ts:41-44 now carries the exact one-line "close does not release" comment the NEXT ticket allows. Good.

Blocker: none.

Concern — duplicated fetch helper. fetchText in hn-monitor-runner.ts:77-81 is byte-for-byte the same logic as defaultFetcher in hn-poller.ts:28-34. That is the same "fetch + assert ok + return text" defined twice. defaultFetcher is not exported, so the runner reimplements it. This is a helpers-over-primitives / single-purpose smell: the default fetch should live in one place and be exported (export const defaultFetcher), with the runner importing it. Duplication today, divergence risk tomorrow.

Concern — FetchError classification gap undermines finding #1. The runner distinguishes "swallowable fetch error" from "fatal journal error" strictly via instanceof FetchError, and only the injected fetcher is wrapped (hn-monitor-runner.ts:44-52). But pollHackerNewsOnce throws its own errors after the fetcher returns — "not JSON" (hn-poller.ts:63) and "not an array" (hn-poller.ts:66). A malformed HN response will NOT be a FetchError, so it terminates the runner. That is still fail-closed (safe), but it means "the loop survives fetch-level errors" is only partially true: it survives network/HTTP errors and dies on malformed bodies. The claim in finding #1 and the test (fetch throw → loop survives) cover the former only; the distinction between "data quality" and "journal write failure" is undocumented.

Notes.

• Field-ordering (finding flow/de vendor wrapper e715601 #3) is correctly fixed — all private readonly fields precede the constructor.
• spec: unknown threading through options is consistent with EventSubmitParams.spec: unknown; the runner rightly does not parse it.
• File sizes are healthy (hn-monitor-runner.ts 89 lines, test 99) and single-purpose.
• One naming nit: spec is the whole flow spec while pollHackerNewsOnce treats it as pass-through to eventSubmit — consistent, but the runner naming HnMonitorRunnerOptions.spec next to pollOptions could invite a future reader to assume the runner validates it. Cosmetic.

Auto-closed: chief consolidating on the newest attempt in the same track (my hand-A #85 for hn-monitor-runner, #88 for cloud-swarm). Keeping this open just multiplies stale iterations against no functioning merge.
