fix(ci): narrow goldens and gate supported conformance - #258
Conversation
Three fixed costs were paid by every job on every run: - Every rust shard pulled the whole LFS golden corpus (365 MB) to feed one test that reads 9.5 MB of v2.335.1 scenarios. Narrow the include to that version. - Every shard built cargo-nextest from source (~300 s). Install the pinned published binary, verified by digest. - rust-cache keyed on the job name, so the four shards kept four cold caches, and its save step is skipped on failure by default, so a red run never primed the next one. Share one key across shards and cache on failure everywhere. The property jobs also ran 'cargo test -- --list' against preloop-runner-server twice, paying for the test-binary build in both; the two verification steps are now one.
Neither conformance job reads `.runner-watch/golden/**` — the light job works off benchmarks/compatibility/runner/behavior and the deep job replays live runners — but both checked out with `lfs: true`, so every pull request pulled the 365 MB corpus before doing anything.
…orpus The two workspace tests that read golden captures (test_golden_acquirejob_payloads_parsing and runner-watch's scenario-07 replay) hardcoded v2.335.1 — the prior baseline — while versions.toml pins the shipped runner at 2.336.0. The pin moved; the tests never followed, so they validated wire parsing against a runner one release behind what preloop ships, and only kept passing because those endpoints didn't change across the two versions. Derive the golden version from versions.toml's runner_version in both tests and in the ci.yml LFS include, so all three track the pin automatically and 2.335.1 stops being load-bearing. Verified both tests pass against the 2.336.0 captures.

The pool section of `preloop status` always reported `busy: 0` even while pool machines ran jobs: `PoolSnapshot.busy` had no writer anywhere. The orchestrator only tracks warm *idle* slots (`set_idle`), and nothing ever set busy — so the count contradicted the runner accounting (`runners busy: 3` vs `pool busy: 0`), the exact mismatch that makes a binding leak hard to read off status. Derive pool.busy server-side in `collect_snapshot_inputs`, where the real per-job execution data lives: count runners that hold an active session request and are in `pool_proven_runners` (so external bring-your-own runners don't inflate the pool's own view). Set it on the snapshot next to the existing `released_bindings` override. Also print `released_bindings` on the pool status line. The timer sweep (`sweep_stale_bindings`) already counts stale bindings it heals, but the counter was only in --json; an operator watching for a leak could not see it in the default output. Regression test asserts pool_busy counts only pool-proven busy runners.

When a normally successful fixture such as 02-trivial-job regresses to failure, this validator still returns PASS because every terminal conclusion is accepted for workflows, jobs, and steps. Since the required Runner light conformance job now uses only --mode local, execution regressions can make every scenario fail while the gate remains green; validate fixture-specific expected outcomes instead of terminality alone.

For 03-cancellation, the manifest contains wait_seconds followed by cancel_workflow, but this helper extracts only the single submission and the main loop then waits for natural completion. Consequently the 60-second workflow succeeds instead of exercising cancellation, so the new runner-light gate cannot detect cancellation regressions; either interpret the remaining manifest actions or exclude scenarios requiring orchestration.

Because exclusions are implemented with name.startswith(prefix), --exclude-prefix 16 removes both the container fixture 16-container-job and the host-executable 163-reusable-caller. The latter is the only checked-in scenario with a fixture-local workflows/ directory, so the newly added reusable-workflow workspace logic is never exercised by this required gate; exclude 16-container-job exactly rather than the whole 16 prefix.

When a deaf runner has already reported step records or uploaded per-step logs, removing the old job_steps entry destroys the only mapping from that attempt's workflow step numbers to its step-<id>.txt blobs. The retry then exposes only the freshly seeded manifest, making the abandoned attempt's partial logs impossible to select or order even though attempt-scoped manifests are explicitly retained elsewhere for re-dispatches; retain the old attempt and create a separate manifest for the new identity.

If a client is following live logs when the runner is reaped, rotating to a new agent-job UUID abandons the old UUID without calling close_live_log. The replacement's eventual completion closes only the new feed, while the old sender remains in live_log_tx, so existing preloop logs -f/SSE followers wait forever and the old buffer and channel stay retained; close the old feed as part of the rotation.

Any local or CI run without public internet, or a self-hosted runner whose unauthenticated GitHub API quota is exhausted, now fails the workspace test suite at .send() before testing repository code. No authorization header is supplied, so shared-runner traffic is limited by the small unauthenticated quota as well; move this mutable external-state assertion to a dedicated authenticated workflow check or skip it unless explicitly enabled.

Running this documented command supplies no --exclude-prefix options, and the harness defaults to discovering every runnable manifest. It therefore selects 64 scenarios, including the reconstructed 2xx-* corpus and the VM-only container/service fixtures that the text below says are excluded, rather than reproducing the 27-scenario runner-light gate; include the workflow's exclusions here or make the supported light set the harness default.

Require the local gate to verify the complete scenario set.
validate_local rejects only zero records. A truncated JSONL file with one valid workflow therefore passes. Line 271 then reports that record count as the expected count.
Compare the records with the required scenario names before success. Report missing and unexpected workflows explicitly.

P3: Avoid making the test suite depend on a live, configurable GitHub API endpoint
Added test performs a live GET to an environment-selected GitHub API endpoint.
Use a fixture by default; isolate and allowlist any opt-in live ruleset check.

Check if this security scanner issue is valid. If so, understand the root cause and fix it. If appropriate, update or add tests. Keep the change focused and preserve intended behavior.

<title>Avoid making the test suite depend on a live, configurable GitHub API endpoint</title>
<evidence>The new live_main_ruleset_matches_required_checks test performs an unauthenticated HTTP GET against the endpoint assembled from GITHUB_API_URL, defaulting to api.github.com. This makes CI correctness and availability depend on an external service and allows the test target to be redirected by its environment rather than validating a controlled fixture.</evidence>
<recommendation>Move this into an explicitly opt-in integration test or a dedicated CI job with a tightly controlled endpoint and timeout; keep the normal test suite on a mocked/fixture response. Validate and allowlist GITHUB_API_URL before making the request, and avoid running the live check for untrusted pull requests unless that isolation is intentional.</recommendation>

The branch drifted four TLS crates ahead of main (rustls 0.23.41->0.23.45, rustls-webpki 0.103.13->0.103.15, aws-lc-rs 1.17.1->1.18.1, aws-lc-sys 0.42.0->0.45.0). cargo-vet's exemptions cover only the older versions, so cargo vet --locked failed with four unvetted deps and the cargo check went red deterministically. Nothing here needs the newer versions, so pin them back to main's vetted set. cargo vet now succeeds; workspace compiles.
- keep abandoned attempt step manifests on retry rotation and close the old live-log feed so followers exit - gate live GitHub ruleset check behind PRELOOP_LIVE_RULESET_CHECK - require expected local conclusions (success/failure/cancelled) - honor cancel_workflow + wait steps in local runner-light harness - exclude 16-container only so 163-reusable-caller stays in the gate - pin runner-watch replay registration version from versions.toml - document the CI exclude-prefix set in docs/conformance.md

Fail action waits when a runner exits.
drive_manifest_actions runs before wait_for_run, while only wait_for_run polls runners. If a runner exits during wait_seconds, the handler remains in time.sleep until that duration ends. If it exits during wait_for_event, wait_until continues until the event timeout because it does not inspect runner state. wait_for_run reports the exit only after the action handler returns.
Pass runners to drive_manifest_actions and wait_until. Use short wait intervals that check each runner's poll() result, and raise the runner-exit error before continuing to wait.

Keep fixture tests strict about versions.toml.
golden_runner_version() delegates to pinned_runner_version(), which returns 2.336.0 when the root versions.toml is unreadable or lacks runner_version. The golden corpus contains v2.336.0, so the tests can continue using that corpus instead of detecting the broken pin.
Use a test-only strict reader that fails when the root pin is unavailable. Keep the fallback only for offline runtime tooling.
