### Fixed

- `checks_state` drops rollup entries belonging to the workflow it runs
  inside — `SELF_WORKFLOW`, defaulting to the ambient `GITHUB_WORKFLOW` —
  before the newest-per-context collapse: the label machine never grades
  its own runs, and an empty name filters nothing (#208).
- A sweep displaced from the shared concurrency queue attaches CANCELLED to
  its PR while its successor attaches elsewhere, so the sweep set
  `blocker:ci-red` off its own displaced run and re-affirmed it every
  cadence (crew#227). A rollup of only self entries now honestly scores
  NONE (#208).
