finding: retrieving a failed CI job's actual assertion takes a manual log-zip dance — script it

Departure-report category ② (可机械化项) from the domain:cli seat (#6024). ⛔ Unassigned,
⛔ no domain:* label — this seat does not produce routing.

The measured problem

When a required check goes red, the two obvious tools do not carry the failing assertion:

get_check_run → output.text is empty for these jobs.
get_job_logs (even with failed_only, even with a large tail_lines) → returns only the
post-step service-container dump, because the container teardown output is what sits at the
end of the log. The test output is thousands of lines earlier.

Measured on PR #9774's Temporal Conformance (live PG + MySQL) failure: both returned nothing
usable, and the seat post carried "the failing assertion could not be retrieved" as a fact for
several hours. It was retrievable the whole time — via the run's log archive:

actions_get method=get_workflow_run_logs_url resource_id={run id}
curl -sSL -o logs.zip "{signed url}"
unzip -q logs.zip -d logs/
# per-step files: logs/{Job name}/{step number}_{step name}.txt

That surfaced the assertion in one grep:

FAIL  src/sql-driver-datetime-mysql-storage.test.ts > … > is idempotent — a second sync leaves the schema alone
Error: Test timed out in 5000ms.

Why a script, not a paragraph

The cost is not the knowledge, it is the five-step sequence and its two sharp edges: the signed URL
is short-lived (mint and download in the same minute), and the archive is ~4MB of ANSI-coded text
that has to be de-escaped before it reads. Every PM and dev who hits a red required check pays this
again, and the failure mode when they do not is worse than paying it — it is concluding "the
assertion is unavailable" and then either guessing at the cause or re-running the job, which is how
a real gate defect turns into folklore.

Suggested shape

scripts/pm/fetch-job-logs.mjs {run id} [job name substring] → downloads, extracts, strips ANSI,
prints the failing step's tail (or the whole step with --full). ⭐ The complementary cheap call is
worth naming in the same place: actions_get method=get_workflow_job reports each step's own
conclusion, so which step failed is one call away with no download at all — and that is
exactly the discriminator the "re-run only when no test body ran" rule turns on.

⛔ Shape is a suggestion, not a spec; sizing, ownership and whether this belongs in scripts/pm/
at all are the receiving seat's call.

Triage: promoted finding → pm:queue · domain:devx · Task. Concrete, well-scoped tool ask: a scripts/ helper that takes a repo/run-or-job reference and prints the failed job's actual assertion text (wrapping the log-zip dance), so agents stop paying the manual sequence per CI failure. Size suggestion: S–M, mechanical.

⚠️ PM: the previous dispatch on this card died mid-run — work survives on disk

Recording this on the card so the state is not mistaken for progress. The agent dispatched by session session_01XqDQYVU5smx29ts9pAErja terminated without opening a PR, so this card has looked pm:dispatched while nothing was moving.

Measured state of claude/issue-9777-ci-failure-retrieval:

pushed to origin: yes
own commits vs origin/main: (none) (0 commits, 1 new file)
PR: none was ever opened — which is why it was invisible in the PR list

Any uncommitted files have been preserved to /home/user/dead-run-salvage/9777/ (tracked.patch + verbatim copies of untracked files). Nothing was lost, and nothing was committed on the dev's behalf — the PM does not write code.

⛔ git stash was not used at any point: the stash stack lives in the common .git dir and is shared across every worktree of this repo, so salvaging through it would have handed this work to whichever agent popped next.

Re-dispatching now as a resume, not a restart.

  "summary": "RULING-1 VERDICT ON THE SALVAGED FILE: near-complete but NEVER RUN LIVE — 996 lines, offline self-test green, and it had never completed a single walk from this container. Its judgment layer (supersession, annotation classification, the pre/post step-numbering gap, roster-vs-shard, the exit table) is measured, correct and now kept intact. What it was missing was transport: node 22's fetch ignores HTTPS_PROXY, so the placeholder token in GITHUB_TOKEN went straight to GitHub and every read answered 401 — the file's own probe then reported PREREQUISITE NOT MET (exit 3) and looked right doing it. A live run now re-execs itself once with --use-env-proxy, reusing check-governed-merges.mjs's exported proxyRearmPlan rather than re-deriving it. I also verified the file's central design claim independently: the Actions log endpoints redirect to productionresultssa{N}.blob.core.windows.net and results-receiver.actions.githubusercontent.com, both answering 403 on CONNECT (measured again today, and the storage-account numeral varies per run, so the constant is now a pattern plus its specimens). /root/.ccr/README.md classifies that as an organization egress denial and says to report rather than route around it, so building on annotations instead of the log archive is correct and mandated. Second change, declared: check-governed-merges.mjs's --self-test trigger had no invokedDirectly guard, so importing it ran its 77 assertions inside the importer's own self-test and put an unrelated file's failures on the importer's exit code — guarded exactly as line 810 of that same file already is. No merge-blocking gate was added (ruling 2); no changeset (ruling 4), skip-changeset label applied and read back as [size/xl, skip-changeset]; no governed surface touched (ruling 3); REST only, no GraphQL (ruling 5). H2: the tool now gives THREE answers, not two — RETRIEVED (file-anchored annotation), NO FILE-ANCHORED ASSERTION but N annotations with content (a gate's own sentence is often the whole answer), and NONE (only 'Process completed with exit code 1.', which is content-free by construction). Only the last is 'could not be retrieved', and it prints the failing step name resolved offline against .github/workflows/ to the command that reproduces it locally. H3: NOT stale — grep across scripts/ and .claude/ for check-runs / annotations_url / actions/runs found only check-required-contexts.mjs, which is a job-NAME pin, not failure retrieval; nothing in scripts/pm/ does any part of this. H4: the tool reads NO history — the only git call is `git rev-parse HEAD` — so the 63-commit shallow clone cannot mislead it; that is now stated in the header, with the condition under which the paragraph retires.",

Ruling 2 kept ci-failure's self-test out of it, so nothing in CI runs it and it can rot unnoticed. That tension is a maintainer call, not mine.",
      "options": [
        "A — leave it out, as ruling 2 directs: it is a tool, not a gate, and a rotted self-test on a hand-run tool costs one agent one round.",
        "B — add one step to the existing Lint & Repo Gates job (no new required context, no new check name), matching the four sibling tools already there.",
        "C — run it from a non-required workflow so the signal exists without blocking merges."

      "recommendation": "A for this PR — ruling 2 is explicit and I did not override it. B is what I would ask for next, as a separate one-line card: it adds no new required context (the check name is unchanged), it is what the four sibling PM tools already do, and the failure it prevents is precisely the one this card is about — a retrieval tool that silently stops working. Deliberately left as a question rather than shipped."

My change created the exposure by importing it, the correct shape is pinned by that same file's line 810, no open PR touches scripts/pm/, and it sits in the same gate family (check:pm-governed-merges, run green both directions). Declared in the PR body."
