Every work-record type carried a stable identifier except tasks, whose rows held only id, workplan_id, title, status and priority — nothing connecting a row to CUST-WP-0067-T01 in the file it came from. Matching was therefore by title, so a renamed heading looked like one task vanishing and another appearing, and the forge-derived reset had to refuse to touch tasks at all. Adds tasks.record_id (nullable: no migration can invent an identity for an existing row) and a backfill that reads the pairing from the repository files, where a task declares both its canonical id and its projection UUID. 5516 pairs across 121 repositories with zero conflicts; 4456 of 6073 cache task rows identified. Diff and reset now key on record_id where present, falling back to a title-prefixed key so an unidentified row stays visibly unidentified. Unknown stays unknown: a row the files do not claim keeps no identity and the reset keeps refusing to act on it, and an existing identity is never overwritten — a mismatch is recorded as a conflict rather than resolved.
