igneum-labs 7e1b1c58e8 CI red watcher: its own workflow_run workflow (ci-red.yml) so the copy on master watches every branch's run whatever ci.yml the branch carries
GitHub runs a workflow_run workflow from the default branch only, so a feature branch no longer waits for a merge of master before its reds are posted. record() reads the FAILED run from RED_WATCH_* (id, attempt, workflow, branch, sha, event, url, actor, title, author: the workflow_run payload) and asks the jobs API for that run, not the watcher's own; the inline GITHUB_* shape stays for a branch with the old `red` job (one line per run id either way). The inline job leaves ci.yml. Self-test covers the workflow_run shape and the full line.

# The red watcher as its own workflow, on workflow_run, so the copy on master watches EVERY branch's ci run whatever
# ci.yml that branch carries: GitHub runs a workflow_run workflow from the default branch only, and the branch's own
# ci.yml never enters it (7 October 2026: the inline `red` job of ci.yml was conditioned on master and release-*, and
# a feature branch would have waited for a merge of master before its reds were posted at all).
#
# One line per failed run (tools/ci/red-watch.mjs record, idempotent per run attempt) to /srv/ci-red/red.jsonl on the
# box; the box's igneum-ci-red.timer posts each new line once to the hidden updates channel, naming the branch, the
# commit, the red check and the pushing author. Runs on the box's own runner (not a GitHub-hosted machine: the billing
# block of 6 October 2026, 18:37Z to 20:10Z, failed every hosted job at start and nobody was told). Never blocks a
# release: it reads the run, writes one line, and ends.
