📝 Walkthrough

Walkthrough

The SDK adds an HnMonitorRunner for polling Hacker News, submitting events, handling fetch errors, and cleaning up on abort. AgentWorker.close() now waits for active executions. Public exports, tests, and operational scope documents were updated.

Changes

Hacker News monitor runner

Layer / File(s)	Summary
Runner scope and operational requirements ops/NEEDS_HUMAN.md, ops/NEXT.md	The operational scope now defines the hn-monitor runner, its completion criteria, deferred work, protected files, and blocked-work procedure.
Graceful worker shutdown sdk/src/worker.ts	AgentWorker tracks active executions. close() detaches dispatch handling and waits for tracked executions to settle.
Polling runner and public API sdk/src/hn-monitor-runner.ts, sdk/src/index.ts, sdk/tests/hn-monitor-runner.test.ts	HnMonitorRunner connects, handshakes, attaches the worker, polls, submits events, reports HnFetchError, handles abort-aware delays, and closes resources. The runner types and classes are exported. Tests cover polling, ordering, abort cleanup, fetch errors, and journal failures.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: ⚪ Minimal · up to 7d29e

This change adds and exports a localized runner implementation with supporting tests and operational documentation; no actionable merge-blocking risk remains beyond normal checks and review.

Poem

A rabbit checks the polling stream,
While workers finish every dream.
Fetch errors hop into a tray,
Then clean shutdown clears the way.
New exports greet the springtime breeze.

maintainability lens — FAIL

Maintainability review — PR #112

Blockers

1. AgentWorker.close() signature change orphans existing callers. sdk/src/worker.ts:41 changes from close(): void to async close(): Promise<void>, but existing call sites in sdk/tests/live-kernel.test.ts at lines 238, 288, 301, 332 still call worker.close(); and discard the returned Promise. The very drain guarantee the new implementation adds (await Promise.allSettled(this.executions)) is fire-and-forget from every pre-existing caller. AgentWorker is publicly exported from sdk/src/index.ts, so external consumers face the same breakage. A stranger reading worker.close(); six months from now has no signal that an await is required.

2. Zero test coverage for the new AgentWorker.close() drain semantics. The executions Set + Promise.allSettled on sdk/src/worker.ts:21,54 are the substantive worker change, yet no test in sdk/tests/* dispatches a step and then asserts that close() waits for the in-flight execution. Reverting worker.ts to its pre-PR synchronous close(): void passes the whole suite. This is exactly the "tests that would not fail if the behavior broke" pattern the brief calls out on the runner side (finding regressions: red/green flows for the 2026-08-27 platform bugs (dormant until gates 2+6) #5) — repeated on the worker side without the same guardrail.

Concerns

3. new AgentWorker(client as JournalClient, ...) at sdk/src/hn-monitor-runner.ts:60 lies. The private RunnerClient interface (lines 12–16) requires only connect/hello/close/eventSubmit, but AgentWorker needs on/workerAttach/stepComplete. A caller passing options.client for a real transport and omitting options.worker typechecks and then crashes on first dispatch. Neither RunnerClient nor RunnerWorker is exported, so consumers can't even see the shape they need to satisfy.

4. pollIntervalMs validation is inconsistent. intervalFromEnvironment() at sdk/src/hn-monitor-runner.ts:105–112 rejects negatives from env; options.pollIntervalMs ?? intervalFromEnvironment() on line 63 lets a user-supplied -1 through into setTimeout, producing a silent hot loop.

5. worker.ts:42 comment satisfies the letter of finding Close Gate 1 deterministic crash-resume rung #2 but not the spirit. "intentionally does not release the server registration" — no WHY, no impact statement, no pointer to the follow-up. Six months on, the reader can't tell if the omission is deliberate design or debt.

6. The fatal-vs-recoverable error contract is spread across three files. hn-poller.ts:63,66 throws plain Error on malformed JSON; the run-loop at hn-monitor-runner.ts:73 swallows only HnFetchError; nothing documents that new fetch-time error classes must extend HnFetchError or the runner dies. Worth a doc comment on either HnFetchError or the catch block.

Note

7. ops/NEEDS_HUMAN.md describes a missing .git mount rather than a design blocker — fine per the workflow, but a stranger rebasing this later will wonder whether it applies to their environment.

history lens — FAIL

Blockers

1. History repeat and false commit claim. Commit 7d29ed9 states: “Verification and adversarial review ran in-run; see ops/reviews/ in the diff.” The diff contains no ops/reviews/ file at all. This repeats the exact evidence-loss failure recorded in ops/DRIVE-LOG.md:1154-1159, where cited transcripts were absent from every commit. It is also an objectively false claim about files touched. The mismatch is especially material because ops/NEXT.md:59-83 requires literal captured output, while ops/NEEDS_HUMAN.md:3-8 acknowledges that the final status verification could not run.

2. New contradiction with settled RFC-0001 decision drive: cloud run 35c4df23 #14. The runner establishes a raw spec as its runtime contract: HnMonitorRunnerOptions requires spec: unknown (sdk/src/hn-monitor-runner.ts:23-35), and each poll submits that raw spec (sdk/src/hn-monitor-runner.ts:67-77). The tests cement raw object injection as the supported API (sdk/tests/hn-monitor-runner.test.ts:26-38). RFC-0001 decision drive: cloud run 35c4df23 #14 explicitly settles that runs reference immutable content-addressed bundle digests, not raw specs or working-tree material. The documented deferrals in ops/NEXT.md:85-99 name integration testing, CLI wrapping, and gate declaration—but not bundle resolution—so the scaffolding exception does not cover this contradiction.

Notes

The implementation does address PR #83’s five listed regressions: typed fetch-only recovery, journal-error propagation, top-declared fields, opt-in AbortSignal, documented non-release plus draining close, and both error-path tests. The Gate 3/Gate 2 wording drift in ops/NEXT.md:1-7 is not treated as a blocker under this lens.

Structure review — PR #112

Verdict on the lens questions

Boundaries: clean. Nothing in this PR touches kernel/. The runner is SDK-side glue composing existing primitives (JournalClient, AgentWorker, pollHackerNewsOnce), exactly where RFC-0001 §4 ("kernel never holds provider SDKs") and hn-poller.ts's own header comment demand. The ops/NEXT.md/NEEDS_HUMAN.md edits are triage artifacts, not product code.

No new primitive — correctly avoided. Finding #2 chose option B (one-line comment on worker.ts close(): "intentionally does not release the server registration") rather than adding a workerRelease verb. That is the right call against settled decision #13 (kernel vocabulary is closed) and AGENTS.md "helpers over primitives." The executions Set draining in-flight dispatch promises is a helper, not a protocol change.

File size / single purpose: fine. hn-monitor-runner.ts (133 lines) holds one class plus its support functions; well under the 500-line smell.

fail-closed honored. run()'s trap discriminates on instanceof HnFetchError and rethrows everything else (hn-monitor-runner.ts:60-63), so a journal_write_failed surfaces as rejection rather than being swallowed. The worker.ts completionReason discipline ('success' | 'worker_error') is preserved.

Concerns (not blockers)

1. Loose DI seam + unchecked cast — hn-monitor-runner.ts:94-97. RunnerClient declares only connect/hello/close + EventSink, yet new AgentWorker(client as JournalClient, …) casts that narrower type to a full JournalClient (which needs on('step.dispatch'), workerAttach, stepComplete). Safe only because today the sole runtime path passes a real JournalClient and tests inject worker too. A future caller passing a RunnerClient that isn't a full client fails at runtime silently. Consider expanding RunnerClient to the verbs it actually feeds, or narrowing AgentWorker constructor param to a structural interface.

2. Fetcher duplication — fetchText/wrapFetcher (hn-monitor-runner.ts:110-123) rebuild the exact fetch/!ok/text() logic already in hn-poller.ts's defaultFetcher. Since defaultFetcher is module-private, either export it and rewrap, or accept the duplication deliberately (note it).

3. Third error category mixed into "fatal" — pollHackerNewsOnce throws plain Error for JSON-parse/not-array (hn-poller.ts:60-67). Those are neither fetch-level (swallowable) nor journal failures, yet run()'s throw error treats them as fatal, so one malformed HN body kills the runner. Likely defensible, but the typed HnFetchError doesn't distinguish "network transient" from "unexpected data"; worth a comment.

4. readonly cause redundantly shadows Error.cause; minor.
