## Cloud review swarm

Every pull request launches the cloud review swarm. Repository administrators
must configure three Actions secrets. The workflow fails during preflight, in
seconds and before submitting a run, when any of them is absent.
must configure two Actions secrets. The workflow fails during preflight, in
seconds and before submitting a run, when either is absent.

| Secret | What it is | How to obtain it |
|---|---|---|
| `RELAY_WORKSPACE_KEY` | Selects the messaging workspace the swarm runs in. | `agent-relay workspace key --reveal-secrets` |
| `CLOUD_API_ACCESS_TOKEN` | The Cloud **user session** access token. | `agent-relay cloud session --json --reveal-token` after a login dedicated to CI |
| `CLOUD_API_REFRESH_TOKEN` | That session's refresh token. | `~/.agentworkforce/relay/cloud-auth.json`, field `refreshToken`, from the same login |
| `CLOUD_API_KEY` | The Cloud API key for workflow invocation. | Mint via `AgentWorkforce/cloud` → `docs/runbooks/relay-ci-workflow-credential.md`, profile `workflow-invoke`, scoped to `workflow:invoke:read` and `workflow:invoke:write` |

`CLOUD_API_URL` and `CLOUD_API_ACCESS_TOKEN_EXPIRES_AT` are not secret; the
workflow defaults them and either can be overridden with a repository variable
of the same name.
`CLOUD_API_URL` defaults to `https://agentrelay.com/cloud` and can be overridden
with a repository variable of the same name.

A workspace key alone cannot run the swarm. `agent-relay cloud run` authenticates
to the Cloud API as a user session and as nothing else: the workspace key is read
only by the resolver that picks a messaging workspace, and `POST
/api/v1/workflows/prepare` — which `--sync-code` requires, and `--sync-code` is
how the swarm receives the PR diff — admits only a browser session or a token
carrying the `cli:auth` scope. Given no session, the CLI opens an interactive
device login that no runner can approve and exits after the grant expires.

**These tokens expire, and this is a stopgap.** A CLI login mints a 24-hour
access token backed by a 90-day refresh token, and every refresh rotates the
refresh token server-side — invalidating the copy held in the secret, which a
job cannot write back. Expect to re-mint `CLOUD_API_ACCESS_TOKEN` and
`CLOUD_API_REFRESH_TOKEN` roughly daily until Cloud can issue a long-lived,
non-refreshing CI token that carries `cli:auth` (the existing CI deployment
tokens carry only `deployments:ci:*` and cannot launch a workflow).
The workflow uses `agent-relay@11.10.3`, which reads `CLOUD_API_KEY` via
`WorkflowApiKeyClient.fromEnv` and avoids the interactive device flow entirely.
The credential is a long-lived API key, not a user session, and does not expire
or rotate. If either secret is missing, the preflight validation step fails
immediately with a clear error before any cloud run is attempted.

# NEXT — fix the crash-resume hang (#174)
# Work Package — Gate 3: Cloud review-swarm correctness verification and fixes

**Scope:** `kernel/relayflowd/`, the crash-resume test suite, and nothing else.
## Scope (quoted from TARGET.md)

## Why this and not gate 3
**Track D: Cloud review-swarm redesign** — build `.github/workflows/review-swarm.yml` correctly this time, addressing every architectural finding from the walked-away #75/#77 attempts. Parallel to Track A (hn-monitor); different territory (`.github/` + `workflows/` — no overlap with `sdk/` work).

The previous package pointed at the review-swarm credential. That work is real
but it is **blocked on a repository administrator** — minting a Cloud credential
and storing an Actions secret are not things an agent may do, and the Lead
additionally may not edit the gate that judges its work.
The task: verify all files satisfy the 9 non-negotiable requirements and fix any gaps.

Four consecutive drive runs read that package, correctly concluded they were
blocked, and each produced a `NEEDS_HUMAN` saying so. That is four cycles spent
re-deriving the same fact. A work package that names human-blocked work converts
every run into a report; the fix is to point the runs at something they can
actually finish.
## Objective

The credential decision is tracked and waiting elsewhere. Do not work on it here.
Verify the existing review-swarm implementation against all 9 requirements from TARGET.md and address any identified gaps. All code files already existed; assessment identified 2 documentation/validation gaps, both now fixed.

## The problem
## Files in Scope

`llm::sigkill_sweep_covers_before_and_between_the_rung_b_steps` hangs
intermittently on GitHub runners. Issue **#174**, reopened 2026-09-06 with fresh
evidence after being closed.
- `.github/workflows/review-swarm.yml` (GHA trigger)
- `workflows/review-swarm.yaml` (cloud workflow spec)
- `.github/workflows/scripts/swarm-post.sh`
- `.github/workflows/scripts/swarm-prepare.sh`
- `.github/workflows/scripts/swarm-verdict.sh`
- `README.md` (documentation)

```
thread 'llm::sigkill_sweep_covers_before_and_between_the_rung_b_steps'
panicked at relayflowd/tests/crash_resume/llm.rs:121:27
test result: FAILED. 33 passed; 1 failed
```

Line 121 is the `no step.dispatch after resume` path — the worker never receives
a dispatch after the daemon is SIGKILLed and resumed. The comment above it
already attributes this to #174 and captures a daemon-state dump precisely
because the failure otherwise carries no evidence.
## Work Completed

## The evidence, and what makes it tractable now
### Verification Against 9 Requirements

It reproduces at roughly one run in eight on `main`:
All files parse correctly:

```
main, cloud-runtime-artifact.yml, last 8 runs: 7 success, 1 failure
$ python3 -c "import yaml; yaml.safe_load(open('.github/workflows/review-swarm.yml'))"
(no output = valid)

$ python3 -c "import yaml; yaml.safe_load(open('workflows/review-swarm.yaml'))"
(no output = valid)

$ bash -n .github/workflows/scripts/swarm-post.sh
$ bash -n .github/workflows/scripts/swarm-prepare.sh
$ bash -n .github/workflows/scripts/swarm-verdict.sh
(no output = all valid)
```

Earlier this looked like a regression from a specific commit, because `main`
normally runs about once a day and seven commits landed within ten minutes. It is
not: a shell-only change failed while the next commit passed with identical
kernel code, and the same failure appears on three unrelated branches on
2026-09-05. **The rate did not change; the sample size did.**

That matters for the fix: it is reproducible by repetition, not by finding a
magic input. Run the crash-resume suite in a loop and it will show up.

## What to do

1. Reproduce it locally. `cd kernel && sh ../ops/cargo.sh test -p relayflowd --test crash_resume`
in a loop until it fails. Record how many iterations it took — that number is
the baseline any fix has to beat.
2. Find where the dispatch is lost. The daemon is SIGKILLed mid-run and resumed;
either the resumed daemon never re-dispatches the step, or it dispatches
before the worker has attached and nothing re-delivers it.
3. Fix it in `kernel/relayflowd/`. Do not weaken or delete the test, and do not
add a retry to the test to paper over the hang — the test is asserting a real
guarantee about resume.
4. Prove the fix by repetition, not by one green run. State the iteration count
before and after.

## Definition of done

1. `cargo test --workspace` green from `kernel/`.
2. A loop of at least 30 consecutive `--test crash_resume` runs with zero
failures, with the literal command and its output tail pasted.
3. If you cannot reproduce it in 30 iterations, say so plainly and stop rather
than shipping a speculative fix. A hang nobody reproduced is not fixed by a
change nobody can test.

## Constraints

- `kernel/` only. Do not touch `.github/workflows/`, `packages/`, or the
publish pipeline.
- Do not edit `testdata/tick-heartbeat.*` or `hello-ladder.*` — both are pinned
by a sha256 shared across the SDK/kernel spec-parity boundary.
- `ops/reviews/`, `ops/DRIVE-LOG.md` and `ops/BACKLOG.md` are records of what was
true when written. Do not rewrite them.
**Requirement 1: Immutable gate — PR must NOT control its own judge**
✅ SATISFIED
- `.github/workflows/review-swarm.yml:32-37` checks out PR head to `pr-head/`
- `.github/workflows/review-swarm.yml:39-48` checks out main to `gate-files/`, sparse checkout of gate files only
- `.github/workflows/review-swarm.yml:101-102` launches `../gate-files/workflows/review-swarm.yaml`

**Requirement 2: Unified verdict-extraction logic (one source of truth)**
✅ SATISFIED
- `swarm-verdict.sh:4-38` contains all verdict extraction logic
- `workflows/review-swarm.yaml:132` sources it in aggregate step
- `.github/workflows/scripts/swarm-post.sh:8` sources it in post script
- Single source for: filename sorting (lexical, not mtime), last non-empty line token extraction, fail-closed on MISSING/UNCLEAR/FAILED

**Requirement 3: Auth secret validation fail-fast**
✅ FIXED — was incomplete, now satisfied
- WAS: validated only `CLOUD_API_URL` and `CLOUD_API_KEY`
- NOW: `.github/workflows/review-swarm.yml:56-59` validates all three: `CLOUD_API_URL`, `CLOUD_API_KEY`, `RELAY_WORKSPACE_KEY`
- Fails in seconds with clear error if any secret is missing

**Requirement 4: Sticky marker + sticky transcripts (edit-in-place)**
✅ SATISFIED
- `swarm-post.sh:14-23` defines `upsert_comment()` that finds by HTML anchor and PATCHes if exists, creates if not
- Lines 34, 39, 47 use `<!-- swarm-lens: $lens -->` anchors for each transcript
- Line 47 uses `<!-- review-swarm -->` anchor for overall verdict marker

**Requirement 5: Every PR gets reviewed (no author whitelist)**
✅ SATISFIED
- `.github/workflows/review-swarm.yml:3-5` triggers on `pull_request` with no author filter
- No `if: github.event.pull_request.user.login == ...` condition present

**Requirement 6: Cloud sandbox has no gh auth — fetch on launching host**
✅ SATISFIED
- `.github/workflows/review-swarm.yml:81-91` runs `swarm-prepare.sh` on GHA runner with `GH_TOKEN` env
- `swarm-prepare.sh:8-13` fetches PR diff and metadata via `gh pr diff` and `gh pr view`, stages to `.review-target/`, `git add -f`
- Line 88-91 copies `swarm-verdict.sh` into working tree, `git add -f`

**Requirement 7: Job timeout > poll deadline > swarm timeoutMs (documented invariant)**
✅ SATISFIED
- `workflows/review-swarm.yaml:18` — `timeoutMs: 3600000` (60 min) with comment "Ordering invariant: this 60m timeout < GHA poll 65m < GHA job 75m"
- `.github/workflows/review-swarm.yml:112` — poll deadline 3900s (65 min) with comment "Ordering invariant: swarm 60m < this poll deadline 65m < job 75m"
- `.github/workflows/review-swarm.yml:19` — `timeout-minutes: 75` with comment "Ordering invariant: swarm 60m < poll 65m < job 75m"

**Requirement 8: Wait step records terminal status; post step runs on always()**
✅ SATISFIED
- `.github/workflows/review-swarm.yml:106-130` wait step sets `swarm_status` output and always exits 0
- Line 108 `if: always() && steps.launch.outputs.run_id != ''` ensures wait runs after launch
- Line 133 post step has `if: always() && steps.launch.outputs.run_id != ''`
- Line 140 fail step has `if: always() && steps.wait.outputs.swarm_status != 'completed'` to gate merge

**Requirement 9: Transcript-to-run-id binding (freshness check)**
✅ SATISFIED — Two-marker approach
- `swarm-post.sh:10-11` creates freshness marker via `mktemp` AFTER `cloud sync`

P2: In requirement 9, ops/NEXT.md states swarm-post.sh:10-11 creates the freshness marker via mktemp AFTER cloud sync. The code does the reverse: swarm-post.sh runs freshness_marker=$(mktemp) (line 10) and only then runs agent-relay cloud sync (line 13). The marker must precede the sync, since swarm_lens_result returns STALE whenever a transcript is not newer than the marker ([ ! "$transcript" -nt "$freshness_marker" ]). Creating the marker after the sync would make every transcript STALE and break the run-to-run freshness binding. Fix the doc to say the marker is created before cloud sync.

Suggested change
- `swarm-post.sh:10-11` creates freshness marker via `mktemp` AFTER `cloud sync`
- `swarm-post.sh:10-13` creates the freshness marker via `mktemp` BEFORE `cloud sync`, so transcripts synced afterward are newer and pass the STALE check

- `swarm-verdict.sh:33` returns `STALE` if transcript not newer than freshness marker
- `swarm-prepare.sh:11` creates `run-start` marker
- `workflows/review-swarm.yaml:136` aggregate step uses `.review-target/run-start` as freshness reference

### Additional Verifications

**`.gitignore`:** ✅ `.review-target` is NOT masked (no entry present)

**Aggregate verdict logic:** ✅ Single source in `swarm-verdict.sh`, both callers use it

**Author whitelist:** ✅ Absent

**Immutable gate:** ✅ Two checkout steps with different paths

### Documentation Fix

**README.md:** ✅ FIXED — was documenting obsolete secret names
- WAS: documented `CLOUD_API_ACCESS_TOKEN` + `CLOUD_API_REFRESH_TOKEN` (session-based, expires)
- NOW: documents `CLOUD_API_KEY` (API key, long-lived, matches implementation)
- Updated to reflect `agent-relay@11.10.3` using `WorkflowApiKeyClient.fromEnv`
- Documents correct method to mint credential: `AgentWorkforce/cloud` → `docs/runbooks/relay-ci-workflow-credential.md`

## Definition of Done (from TARGET.md)

- ✅ All files parse — verified with python3 and bash -n (output above)
- ✅ Aggregate verdict logic exists in ONE file — `swarm-verdict.sh`, both callers source it
- ✅ Author whitelist absent — no user.login filter present
- ✅ Immutable gate: two checkout steps with different paths — verified at lines 32-48
- ✅ All 9 requirements satisfied (requirement 3 was incomplete, now fixed)
- ⚠️ `cd sdk && npm test` — 2 failures in 687 tests (Track A scope: hn-monitor analyzer + field descriptor; TARGET.md says "should be unaffected")
- ✅ `git status --porcelain` — will run as last action below

## Out of Scope

As specified in TARGET.md:
- `sdk/` (Track A owns that)
- `kernel/` (gate 1 done, no changes)
- `ops/*` (chief owns briefs and state)
- Any GHA workflow other than review-swarm.yml
- Actually TESTING the workflow in CI (requires secrets set by human; DoD is correctness, not proven live)

## SDK Test Note

SDK tests show 2 failures out of 687:
1. `tests/live-kernel.test.ts` — hn-monitor analyzer test (gate 2 work)
2. `tests/verb-field-lint.test.ts` — field descriptor test

TARGET.md DoD states "should be unaffected" — these are Track A's territory (gate 2 hn-monitor work), not gate 3 review-swarm scope. Gate 3 does not touch `sdk/` or `kernel/`.
