Written by Forge, a Commonly agent. Pod: 6a692a1be833c668acdb84cf (TASK-729).

The daily first-user walk (TASK-706) now writes a machine-readable pass/fail signal for SRE's auto-rollback job.

What changed

• scripts/first-user-walk.mjs: the walk body is runWalk(deps), so its production path runs under test with an injected fetch, clock and paths. The CLI entry is unchanged in behaviour.
• Every run overwrites ~/.commonly/state/walk-729/result.json (override COMMONLY_WALK_RESULT), atomically. It holds sha, timings, each step as pass / fail / not-covered with a reason, the cleanup verdict, and overall.
• Exit codes match overall: 0 pass, 1 fail, 2 incomplete.
• docs/runbooks/first-user-walk.md: documents the file and what SRE reads.

Decision for review

• Today every full run is incomplete (exit 2), because the Bring-your-own connect step is still not covered. A not-covered step never counts as a pass. I did not map incomplete to 0, since that would claim a check that never ran. SRE should roll back on fail only.

Carry-over (#3126 CodeRabbit)

• Test through the production path: pod create fails and the list has no match. The manifest records the pod name with needs-admin-purge.

Safety

• Password, token and email are scrubbed from the result, the step reasons and the manifest. Tests assert the result and manifest never contain the password or the email.
• The walk still deletes only what it created. No cleanup rule changed.

Tests

• node --test scripts/first-user-walk.test.mjs: 5/5 (pass signal, forced fail, no credential in output, ambiguous pod create, missing password).
• node --test scripts/first-user-walk-cleanup.test.mjs scripts/first-user-walk-mode.test.mjs: 32/32.

Walkthrough

The first-user walk is refactored into an injectable runner. It records step and cleanup outcomes, writes an atomic JSON result for each run, and returns an exit code. The BYO connect step is recorded as not covered.

Changes: First-user walk

Layer / File(s)	Summary
Runner contract and request handling scripts/first-user-walk.mjs	The script exports runWalk with injectable network, filesystem, time, and logging dependencies. API requests use timeouts and reject redirects. Errors redact the password and email before logging or recording.
Walk step execution scripts/first-user-walk.mjs	The runner records signup or signin step outcomes, recovers ambiguous pod creation, and polls hosted replies. It records BYO connect as not covered, resulting in an incomplete run unless cleanup fails.
Cleanup and per-run results scripts/first-user-walk.mjs, scripts/first-user-walk.test.mjs, docs/runbooks/first-user-walk.md	Cleanup records unresolved resources and survivors. The runner atomically writes the result JSON and returns its exit code. The CLI, tests, and runbook cover the result fields, status mapping, and credential exclusions.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: Low · up to 48f94

Before acting on a result, operators must confirm it belongs to the latest run. Cleanup-failure exit reporting also needs a full-run test; these bounded risks do not establish a production failure that blocks merge.

Write a failing placeholder before the walk starts.

225-228: Minor · Stability & Availability · Quick win

Write a failing placeholder before the walk starts.

A run that stops before its final write leaves the previous result.json in place. The runbook says incomplete is "not-green but not as a regression," and SRE rolls back on fail only. A stale incomplete file can therefore hide a failed or unfinished run. This happens when mkdirSync, writeFileSync, or renameSync throws, or when the process is killed before the final write.

Write a placeholder before any request. Calling writeResult(1, false) produces overall: "fail" and cleanup.status: "running". The final write then replaces it. A reader that reads during a walk sees fail until the final write, so SRE must read the file only after the run ends.

Suggested fix

   };
 
+  // Placeholder until the final write. A run that stops early leaves fail, not the previous result.
+  writeResult(1, false);
+
   let exitCode = 0;
   let cleanupOk = true;

leave a stale result; preserve the existing final write that replaces the
placeholder.

Tie freshness to the scheduled invocation.

82-84: Minor · Data Integrity & Integration · Quick win

Tie freshness to the scheduled invocation.

The walk identifier is generated from the process's private start timestamp. The CLI does not accept that identifier. It prints the identifier only after the result is written, so a killed invocation cannot provide one for SRE to compare.

The schedule runs the walk twice. If the second invocation is killed, the first result can still have the current SHA and a post-deploy finishedAt. Use the caller's recorded start time for the specific invocation instead of requiring an independently known walk.

📝 Proposed runbook change

-Every run, including one that fails before its first step, overwrites
-`~/.commonly/state/walk-729/result.json` (override with `COMMONLY_WALK_RESULT`).
+Each run that reaches the result-writing step, including a run that fails
+before its first step, overwrites
+`~/.commonly/state/walk-729/result.json` (override with `COMMONLY_WALK_RESULT`).
+A run that is killed, or that cannot write the file, leaves the previous file
+in place.
 Write is atomic (temp file, then rename), so a reader never sees a half file.
+Before acting on the file, confirm that `sha` matches the deployed SHA, that
+`finishedAt` is after the deploy, and that `startedAt` is at or after the
+caller-recorded start time for the scheduled invocation being evaluated. If any
+check fails, the walk did not produce a usable result for this invocation.

leave the previous file intact. Tell readers to verify the result’s deployed

Add a runWalk test for cleanup-only failure.

Make the fixture echo both credentials in the recorded error.

fakeBackend returns { ok: true } for the preview failure, so the test passes when redact is removed. Keep the manifest absence checks, but assert redaction in the result. The preview error is not written to manifest survivors on this path.

HEAD 5d55823

Opus-class review of the fix head. No blockers. 42/42 walk, cleanup and mode tests pass. Each fix was checked by breaking it in a scratch copy: entry guard, escaped-form redaction, signin deleteAccount, cleanupRan, walkMode default, sha source, and both recover() calls. No path deletes what the run did not create. Signin mode deletes only recorded ids and never the account.

Follow-up at 48f943c (not reviewed as a gate, one line plus a runbook note): a cleanup that throws is no longer reported ok, and not-chosen is documented.

GATE: PASS

[lilyshen0722]

Behaviour changes from the original walk, for the press:

• The stdout step lines use result and reason where they used ok and error. Nothing in the repo reads that output.
• Bring-your-own prints NOT COVERED on stdout and no longer sets the failing step name.
• Step reasons and cleanup errors are redacted (password and email, raw and JSON-escaped).
• A failure before any step now writes the result file.
• The result is written at the end of a run, so a killed run leaves the previous file.
• An empty --base falls back to COMMONLY_API_URL or prod. The original crashed. The shared email is still refused on prod.
• sha is taken only from WALK_SHA, else null. The local checkout HEAD is never used.

Preserve a pre-existing pod in the sign-in integration test.

184-184: Trivial · Functional Correctness · Quick win

Preserve a pre-existing pod in the sign-in integration test.

The fixture creates the shared account but no pod, so an assertion that the final pod list is empty would pass even if runWalk deleted an existing shared-account pod. Seed one pod and assert that only that pod remains after cleanup.

Suggested test change

   const dirsFor = dirs();
   const { fetchImpl, state } = fakeBackend({ seeded: true });
+  state.pods.push({ _id: 'old', name: 'Existing', createdBy: USER_ID, members: [] });
   const { exitCode, result } = await run(fetchImpl, dirsFor, {
...
-  assert.equal(state.pods.length, 0);
+  assert.deepEqual(state.pods.map((x) => x._id), ['old']);
