Forge-projection retirement stamps the slug with "@retired-YYYYMMDD" and sets
projection_retired_at but leaves status untouched. Three railiance-platform
rows retired on 2026-08-26 while blocked (and re-set to blocked by a
2026-09-27 user-requested correction) therefore failed C-07 permanently, with
no file the repo could add. Their canonical successors are file-backed
RPF-WP-0015/0025/0027.
_check_orphan_db now reports retired rows (projection_retired_at, or the slug
stamp on APIs that do not yet expose it) as C-08 INFO. WorkplanRead exposes
projection_retired_at so read clients can filter tombstones.
