Bundle: ci-pipeline-cleanup, Phase 12.
NEW docs/ci-pipeline.md (operator-facing guide to the on-push pipeline):
- Trigger model (push, daily, tag)
- Per-job deep-dive for all 5 CI jobs + 2 CodeQL jobs
- The 20 regression guards table with what each catches
- Coverage threshold management
- Three-tier make convention (verify, verify-deploy, verify-docs)
- Adding a new check (where it goes, auto-pickup)
- Troubleshooting matrix
- Status check accounting (19 → 7)
- Required GitHub branch protection list (operator action)
NEW cowork/ci-pipeline-cleanup/v2.X.0-release-notes.md — operator-facing
release notes covering all 13 phases + the operator action items
post-merge.
NEW cowork/ci-pipeline-cleanup/reddit-beat.md — Reddit / HN announce
draft (don't auto-post; operator times manually after the tag lands).
Active Focus updated in cowork/CLAUDE.md (workspace, separate edit
since CLAUDE.md isn't in the repo) — added ci-pipeline-cleanup entry
to 'Recently shipped bundles' + new env-var summary line + two new
operator-decision items (RAM headroom + branch protection rules).
