From 3e051a722327a6fd89de365249d11cf820bc0f5d Mon Sep 17 00:00:00 2001 From: kjgbot Date: Mon, 31 Aug 2026 13:08:51 +0200 Subject: [PATCH] drive: cloud run d4bb89e6 Work produced by cloud run d4bb89e6-ff67-430f-972c-dfbbfb077584 in a workflow sandbox and delivered from this host, because a sandbox has no remote and no GitHub token.

CODE task, SDK-side. +**Scope:** Build sub-PR A of the Gate 2 push: a real `hn-monitor` polling runner in the SDK. CODE task, `sdk/src/`-side. -This run is pinned to **gate 3** and must not work on any other gate. +**Context:** RFC-0001 §3 gate 2 is done when "hn-monitor runs as a relayflow in production, triggered by its real events, with zero bespoke persistence." Every primitive already exists in this repo — event triggers (PR #14, `kernel/relayflowd/tests/event_wake.rs`), the flow spec (`testdata/hn-monitor.flow.yaml`), the poller (`sdk/src/hn-poller.ts`), the agent worker (`sdk/src/worker.ts` from PR #53), a one-shot demo (`sdk/src/demo-hn-monitor.ts`) — but nothing has ever run them together as a continuous workload. This PR fixes that. ## Objective -Promote the throwaway worker the tests already build into a real SDK component -that can execute agent steps by running their declared CLI as a subprocess. +Add `sdk/src/hn-monitor-runner.ts`. It composes the existing pieces into a continuous runner: -## Context +- constructs a `JournalClient` connected to the running `relayflowd` socket +- constructs an `AgentWorker` (from `sdk/src/worker.ts`) and calls `worker.attach()` for `agent` steps +- loops: + 1. `pollHackerNewsOnce(spec, sink)` (from `sdk/src/hn-poller.ts`) + 2. sleep `POLL_INTERVAL_MS` (env-configurable, default 60000 = 60s) + 3. exit on SIGTERM/SIGINT cleanly (drain in-flight steps, close client) +- exported from `sdk/src/index.ts` -Nothing in this repo can execute an agent step. Searching for `workerAttach` / -`step.complete` finds only TESTS (`sdk/tests/live-kernel.test.ts`, -`journal-client.test.ts`, `journal-client-loopback.ts`) and the protocol -definitions. `sdk/src/cli/run.ts` only OBSERVES worker leases and waits for one -that never arrives. - -The kernel's dispatch, lease and claim machinery is real and tested. The worker -side of the protocol is simply unimplemented, and that is what blocks gate 2 -("a workload RUNS as a relayflow" — today a run can only be shown CREATED) and -gate 3 ("every claim/lease/retry served by the kernel"). - -`sdk/tests/live-kernel.test.ts` around the `live-manual-agent` case (line 288) -shows the whole shape: connect, `hello`, `workerAttach` with pins, receive -`step.dispatch`, act, complete. The protocol is already proven there. +Keep it small and honest: +- the worker must attach BEFORE the first poll (a run parked because no worker attached is only revived by `run.resume`; the live-kernel suite pins this) +- no retry inside the poller (`hn-poller.ts` already handles single-fetch failures with a typed error; the loop just moves to the next tick) +- no scheduling logic beyond the sleep (the kernel owns retry and dedupe policy) +- no LLM calls; the runner is glue, not a reviewer +- graceful shutdown: SIGTERM sets a shutdown flag; current poll finishes; worker drains via `worker.close()` (already exists in `sdk/src/worker.ts:41`) ## Files in scope -- `sdk/src/worker.ts` — new file, the worker implementation -- `sdk/src/index.ts` — export the worker -- `sdk/tests/live-kernel.test.ts` OR a new test file — add a test that runs a - real flow with an agent step end to end against a live `relayflowd`, with - this worker attached, and asserts the step reaches `done`. +- `sdk/src/hn-monitor-runner.ts` (new) +- `sdk/src/index.ts` (add export) +- `sdk/tests/hn-monitor-runner.test.ts` (new) ## Definition of done -ALL of the following must hold: - -1. The worker in `sdk/src/worker.ts`, exported from `sdk/src/index.ts` - -2. A test that runs a real flow with an agent step end to end against a live - `relayflowd`, with this worker attached, and asserts the step reaches - `done`. `sdk/tests/live-kernel.test.ts` already starts a daemon — follow - that pattern. - -3. **The worker must attach BEFORE the run starts.** A run that finds no worker - parks, and attaching afterwards does not re-drive it — `run.resume` is what - picks a parked run back up. That contract is pinned in the live-kernel - suite; do not fight it. - -4. The worker must: - - attach for `agent` steps with the pins it holds - - on `step.dispatch`, run the step's declared `cli` as a subprocess - - report the result back through the existing protocol (`step.complete`, and - the failure path when the CLI exits nonzero) - - nothing speculative: no retries of its own, no scheduling, no LLM calls. - The kernel owns retry and lease policy — do not reimplement it. - -5. `cd sdk && npm test` must be green. Run it and paste the literal command and - output tail showing test counts. - -6. `cd kernel && sh ../ops/cargo.sh test` must be green. Run it and paste the - literal command and output tail showing test counts. - -7. EVERY new test confirmed to FAIL against current code, with the literal - failing output quoted in the summary. - -8. As your LAST action, run `git status --porcelain` and paste it. - -## Explicitly OUT of scope - -- LLM steps — not in the gate 3 scope -- Retry logic in the worker — the kernel owns retry policy -- Scheduling or lease management — the kernel owns lease policy -- Optimizations, abstractions, or speculative features -- Changes to the kernel -- Changes to existing tests (except adding new test cases) -- Work on any gate other than gate 3 - -## If blocked - -If gate 3 is genuinely unreachable from the current state, write -ops/NEEDS_HUMAN.md saying exactly why and still end with ASSESS_DONE.
