When two push runs of the same workflow/ref fail concurrently (particularly the hour-long bench-eql runs), both reporters can finish the lookup before either creates the issue, take this else branch, and create duplicate issues with the same title. This violates the stated one-open-issue-per-workflow-and-branch behavior; serialize reporters using a concurrency key derived from the workflow/ref and account for search-index lag when performing the lookup.
Useful? React with 👍 / 👎.

Fixed in e9fef68. The report job has a concurrency group per workflow and branch (report-unattended-failure-<workflow>-<ref_name>) with cancel-in-progress: false, so a second reporter waits and then finds the first one's issue. The lookup now lists issues directly rather than through the lagging search index. One limit remains: GitHub keeps only one pending run per group, so if three reports overlap, the middle one is dropped. The comment in the workflow says so.

Blocking: test-eql.yml and fuzz.yml fail at startup on this head
On fee9dc52, two workflows did not start:
- Test EQL, run 37897081288:
startup_failure - Fuzz (crates), run 37897081235:
startup_failure
gh pr checks 1146 does not show these runs, because a startup failure creates no check run. Thus the PR looks green, but it is not. On main, this breaks Test EQL on every pull request, push and nightly run, and ci-required never reports. The two workflows that failed are the two that this PR changed and that trigger on pull_request. bench-eql.yml and macro-expand-eql.yml have no pull_request trigger, so this PR did not exercise them. Expect the same failure there.
The API does not give the startup error text. The most probable cause is the permissions handoff to the called workflow (see the inline comment). Open run 37897081288 in the browser to read the exact message before you change the code.
After the fix, push again and confirm that Test EQL and Fuzz (crates) start on the PR. actionlint does not detect this class of error, and the new test does not either.
Points already raised
I agree with the open points from CodeRabbit (--limit on the issue lookup) and Codex (concurrent reporters can open two issues). I do not repeat them here.
Suggested follow-up PR
test-eql.ymlhasmerge_group: {}(inert today). The report condition does not exclude it. If the repo turns on a merge queue,github.ref_nameisgh-readonly-queue/main/pr-<n>-<sha>. Each queue failure then opens a new issue with a unique title, and the PR author already sees that failure. Addgithub.event_name != 'merge_group'to the condition, or write down why it is acceptable. The test pins the condition text atscripts/__tests__/unattended-failure-report.test.mjs:35, so update it in the same change.- Add a guard to
unattended-failure-report.test.mjsthat checks the called workflow requests no permission that the caller job does not grant. That is the property that failed here, and nothing in the repo checks it.
No changeset is necessary. This is CI-only.

Probable cause of the startup failures. The caller job grants only issues: write (for example test-eql.yml:1056-1057), so every other scope, contents included, is none for the called workflow. This file requests contents: read at the workflow level. A called workflow can only reduce the permissions it receives, and GitHub rejects the run at startup when it asks for more.
Do one of these:
- Remove the workflow-level block, or set it to
permissions: {}. The job needs onlyissues: write, andgh issue list/gh issue createwithGH_REPOdo not needcontents. - Or grant
contents: readin each of the four caller jobs. Then changescripts/__tests__/unattended-failure-report.test.mjs:108, which pins{ issues: 'write' }.
Confirm the exact message on run 37897081288 first. If the message names another cause, fix that instead.

Confirmed and fixed in f8e012b. The run page for 37897081288 shows: "Error calling workflow '.../_report-unattended-failure.yml@...'. The workflow is requesting 'contents: read', but is only allowed 'contents: none'." Fuzz run 37897081235 shows the same text. The reporter now has permissions: {} at the workflow level. Its job keeps issues: write and needs no contents. unattended-failure-report.test.mjs now checks that each caller's report job grants every scope that the reporter asks for, at the workflow level and in each job. It fails on the old file.

A scheduled run, or a push to main, has no pull request to turn red, and GitHub mails its failure to one person. The nightly fuzz campaign, the EQL matrix, the macro-expand drift check and the EQL benchmarks could all fail without anyone noticing. Each now ends with a job that opens an issue, or comments on the open one, through a shared reusable workflow. The report job runs on every event except pull_request and workflow_dispatch rather than on schedule only, so it also covers post-merge failures and any trigger added later, and satisfies the existing rule against job conditions that enumerate events. A new test requires every scheduled workflow to call the reporter or give a reason, and every report job to need all other jobs. The expression evaluator learns failure(), which callers must set explicitly.
Test EQL and Fuzz (crates) stopped starting on this branch. Both runs
ended in startup_failure with "Error calling workflow
'.../_report-unattended-failure.yml'. The workflow is requesting
'contents: read', but is only allowed 'contents: none'." A called workflow
gets at most the calling job's grant. The report jobs grant only
`issues: write`, and GitHub checks the called file's workflow-level block
against that grant even when its job sets its own. bench-eql.yml and
macro-expand-eql.yml call the same file and would fail the same way on
their first push or scheduled run.
The reporter now declares `permissions: {}` at the workflow level. Its job
reads and writes issues through GH_REPO and needs no checkout, so
`issues: write` is all it asks for.
A startup failure creates no check run, so the PR looked green, and
actionlint does not model the handoff. unattended-failure-report.test.mjs
now holds every caller's grant over every scope the reporter asks for, at
the workflow level and in each job, and fails on the shape that broke.
Three gaps in the reporter's "one open issue per workflow and branch": - The lookup used `gh issue list --search`, which returns 30 ranked results by default and reads a search index that lags. The right issue could fall outside the window, and an issue opened moments earlier could be missed. It now lists every open issue directly and matches the exact title. - Two failed runs of one workflow on one branch could both look, both find nothing and both open an issue. The report job now has a concurrency group per workflow and branch, without cancelling, so the second finds the first's issue. - test-eql.yml has a merge_group trigger. A merge queue run's ref is unique per attempt, so each failure would open a new issue, and the author already sees the failure on the merge. The report condition now also excludes merge_group in all four callers.

Problem
A scheduled run has no pull request to turn red, and GitHub emails its failure to one person: whoever last edited the
cronline. A push run's failure goes to whoever pushed. Four workflows could therefore fail without the team noticing:fuzz.yml: the nightly fuzz campaign uploads the crash input as an artifact and does nothing else.test-eql.yml: the full PG 14-17 matrix, on push tomainand nightly.macro-expand-eql.yml: the nightly check that thecargo expandsnapshots haven't drifted.bench-eql.yml: the benchmarks, on push tomainand nightly.Only
musl-build-image.ymlalready reports its failures, by opening an issue.Change
_report-unattended-failure.yml. It opens an issue titled<workflow> failed on <branch>, labelledneeds-triage. If that issue is still open, later failures are added to it as comments, so each workflow has one thread rather than a new issue every night. The issue body and each comment link the run, name the event and commit, and include the calling workflow's instructions for what to do.reportjob. The job needs every other job in its workflow. Its condition isfailure() && github.event_name != 'pull_request' && github.event_name != 'workflow_dispatch'.schedule. Stack's own tests reject conditions that list allowed events, because a trigger added later would be skipped silently.mainfailures oftest-eqlandbench-eqlare reported too. Their run is the only check of the merged result, and it was going just as unseen.scripts/__tests__/unattended-failure-report.test.mjs. It scans.github/workflowsand requires:codeql,osv-scanner,musl-build-image);reportjob'sneedsto list every other job in its workflow. Otherwise a job added later could fail without being reported.lib/expressions.mjsnow understandsfailure(). The result must be supplied by the caller; if it isn't, evaluation throws, as for any other expression it can't evaluate.workflow-dispatch-job-conditions.test.mjssetsfailure()to true, the same way it sets job outputs to their passing values.
