A task id written as a bare "T01" is unique only inside its own workplan.
Stored as a canonical identifier it makes every workplan's first task share one
identity: 51 such ids were assigned to 148 rows on central before this was
caught, found because identified rows outnumbered distinct identities.
Short ids are now qualified as WORKPLAN-ID-T01. A short id in a file with no
workplan id in frontmatter is left unidentified — an identity that is not unique
is worse than none, which is the same rule the rest of this module already
follows.
The 136 affected rows on central have been cleared so the corrected backfill can
reassign them; the backfill never overwrites an existing identity, so they had to
be nulled rather than re-derived over.
