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.

"""Derive a repository's work-record projection from the forge (STATE-WP-0083-T01).
|
|
|
|
`ADR-012` decision 1 makes the forge the projection source. Central does its own
|
|
reading: it clones the repository's default branch and derives from that, rather
|
|
than accepting a projection computed elsewhere — which `ADR-010` decision 5
|
|
forbids.
|
|
|
|
This module is read-only. Deriving must be safe to run at any time, because it is
|
|
what makes the reset in `T03` verifiable: you can always ask what the projection
|
|
*should* be without changing anything.
