### Added

- A `post-merge` item with no comment for 7 days now draws one nudge from the
  issue sweep: the wake evidence is owed. A starving criterion used to be
  found only when someone happened to run the right read (#254).
- Label churn does not reset that clock, and neither does an assignment: on
  `post-merge` an assignee is an invalid composition, not activity, and it
  must not buy the item another 7 days of silence (#254).
- The nudge names the triage actor from `triage-actors=`, not the human
  reviewer: `post-merge` is triage's completion queue, so the starved wake
  condition is triage's to answer (#254).
- It links the item and parses nothing from the body — which criterion
  starved is prose, and the machine never judges prose (#254).
- Like the ruling nudge it carries no idempotency marker on purpose: the
  comment is itself activity, so the rule self-rate-limits to one nudge per 7
  quiet days. Comment-only — no path here writes a label (#254).
