A rabbit checks the news at dawn
Each event hops safely on
Workers attach, then signals call
Errors pause, but polls march on
Journals close when runs are gone

Maintainability review — PR #119

Blockers

• sdk/src/worker.ts:42 — the comment asserts what the code does NOT do, backed by an unverified cross-file assumption. "Does not release server state; closing the owning JournalClient connection does that" is a promise about kernel behavior (that dropping the connection releases the worker attachment) with no test, no protocol reference, and no assertion in this diff. AGENTS.md rule 4 is "fail closed"; the brief also allowed "add workerRelease" as the alternative. A stranger in six months reading close() cannot tell whether calling it alone is safe — they must go read kernel/relayflowd and hope the behavior hasn't changed. Either add the workerRelease verb the brief pointed at, or rewrite the comment as a caller obligation ("callers MUST close the owning JournalClient after close() — server-side worker state is released only on connection drop") and add a test that exercises the sequence.

Concerns

• sdk/src/hn-monitor-runner.ts:36-42 implicit factory contract. RunnerClient deliberately omits on/off, but the default workerFactory casts client as JournalClient and hands it to AgentWorker, which calls this.client.on('step.dispatch', ...) (worker.ts:31). Overriding only clientFactory (a plausible future use — e.g. an in-process double) will crash on on is not a function. The tests hide this by always overriding both factories together. Either widen RunnerClient to include the EventEmitter surface the worker needs, or document that the two factories must be replaced as a pair.

• sdk/src/hn-monitor-runner.ts:96-99 env var is un-namespaced and silently falls back. POLL_INTERVAL_MS is generic enough to collide with any other component and NaN/-1/"foo" all quietly become 60_000 with no log. Rename to HN_MONITOR_POLL_INTERVAL_MS, and either throw on parse failure or narrow the guard to > 0 (currently >= 0 permits a tight loop).

• sdk/src/hn-monitor-runner.ts:79-83 JournalSubmissionError is control-flow-only and undocumented. Its sole purpose is to distinguish journal errors from fetch errors across the sink boundary at line 52. A future maintainer touching the sink can easily remove the wrapper and reintroduce error-swallowing (the exact regression PR drive: cloud run 87bb2f91 #83 was closed for, finding gate1: kernel + sdk skeletons (bootstrap relayflow output) #1). Add one line on the class explaining why it exists.

• sdk/src/hn-monitor-runner.ts:35-46 abort does not cancel an in-flight fetch. signal is never threaded into pollOptions(), so pollHackerNewsOnce (and its fetcher) cannot observe abort. The "drains in-flight" test at sdk/tests/hn-monitor-runner.test.ts:55-70 masks this by using a fetcher that resolves promptly after abort. In production against real HN, shutdown will block until the socket completes. Either pass signal through PollOptions or note the shutdown-latency contract.

Notes

• hn-monitor-runner.ts:68-74 pollOptions() must be hand-maintained against PollOptions shape — trivial today, easy to skew later.
• The "onPollError called on fetch throw" test doesn't guard against a real bug (JSON parse throw, "not an array" throw from hn-poller.ts) being classified as a poll error. If that's intentional, say so; otherwise narrow the catch.

history lens — FAIL

Blocker

• Commit 29f1937 states: “Verification and adversarial review ran in-run; see ops/reviews/ in the diff.” That is false. The diff contains only ops/NEXT.md, sdk/src/hn-monitor-runner.ts, sdk/src/index.ts, sdk/src/worker.ts, and sdk/tests/hn-monitor-runner.test.ts; no review transcript exists. This repeats the evidence-loss pattern recorded in ops/DRIVE-LOG.md, which was deliberately corrected by requiring persisted transcripts rather than narrated review claims. The implementation and tests occupy sdk/src/hn-monitor-runner.ts:1-112 and sdk/tests/hn-monitor-runner.test.ts:1-130, but neither contains the claimed review evidence. This is a direct commit-message untruth about files/evidence.

Concerns

• sdk/src/hn-monitor-runner.ts:50-68,99-111 uses a process-local polling loop and timer. It does not yet establish RFC-0001’s durable trigger/liveness semantics. Because ops/NEXT.md:5-11,55-61 explicitly scopes this as scaffolding and defers end-to-end proof, this is not a blocker under the requested lens.
• ops/NEXT.md:47-54 requests mutation and test output, but the PR does not carry that evidence. Again, absence alone would be non-blocking for scaffolding; the blocker is the commit’s affirmative, false pointer to evidence supposedly present in the diff.

Notes

• The journal-error wrapper at sdk/src/hn-monitor-runner.ts:55-78 preserves fail-closed behavior, and sdk/src/worker.ts:39-44 documents rather than silently changing release semantics. I found no settled RFC-0001 contradiction in those changes.

Structure Review — PR #119

Scope check. The change is purely sdk/src/ + sdk/tests/ (+ an ops/NEXT.md rewrite). No kernel/* edits, no new journal verbs, no primitive added. The kernel stays closed and tenant-unaware, product logic (HN polling) stays SDK-side, exactly where hn-poller.ts already lives — consistent with RFC-0001 §4 and the gate-6 "helper over primitive" stance. hn-monitor-runner.ts is 112 lines, single-purpose, composes existing pieces. No file outgrows its purpose.

Concerns.

1. DI seam duplicates the client contract and forces a cast. RunnerClient/RunnerWorker (hn-monitor-runner.ts:9–22) are hand-maintained subsets of JournalClient/AgentWorker with Promise<unknown> returns, then the default workerFactory casts this.client as JournalClient (line ~45). That's a second source of truth for the client surface plus an unsafe cast. The poller already models this cleanly with the minimal EventSink interface (hn-poller.ts:21); the runner could type against JournalClient directly and inject a fake, avoiding both the duplicate contract and the cast. This skirts AGENTS.md "no speculative abstraction" — the factories exist only to smuggle test doubles past strong typing.

2. JournalSubmissionError → unwrap → rethrow error.cause (hn-monitor-runner.ts:37–39, 84–93) is a marker-type round-trip purely to distinguish journal failures from fetch failures. It works, and it correctly preserves the fail-closed behavior (journal throw terminates the loop), but it discards the typed failure semantics RFC covenant 2 asks for — the journal failure surfaces as a raw cause, not a declared failure kind. Acceptable for SDK scaffolding, but worth flagging.

Notes.

• worker.close() (worker.ts:42) took the comment path that the tick explicitly permits ("closing the owning JournalClient connection does that"). The comment now asserts a server-side behavior that this PR does not verify; close() remains semantically asymmetric (named for teardown, does not release). Fine for this tick, but the claim should be pinned when the workerRelease verb eventually lands.
• pollIntervalFromEnv reads process.env.POLL_INTERVAL_MS at construction: fine, minor global-config coupling.
• No completionReason regression; the runner is not a step and produces no completions.

No blockers. The shape matches the RFC — composition of SDK surfaces, fail-closed, no kernel contamination.
