Thirteenth resolver from the verified coverage map on #3115.
`sweepTerminalColumns` was uncovered: the case directly above it asserts
the terminal skip using `done` and `archived` — **the ids** — so
blinding the resolver left the file green.
## What the literal costs
The skip matched nothing on a renamed board, so **finished cards were
scanned as live**, and a card parked in a renamed completion lane could
be reported stalled.
A watchdog that cries about completed work is worse than a quiet one: it
trains operators to ignore the alert. That is the exact failure this
sweep's own dedup logic was built to avoid, reintroduced through the
lane vocabulary.
## The case
The renamed twin of the existing terminal-skip test — same assertion,
same shape, different vocabulary. That is the whole point: the original
passes either way, so it cannot see the conversion.
**Measured:** 10 pass; blinding `sweepTerminalColumns` fails exactly
this case.
## Map status
**13 of 26 pinned** across 12 merged PRs, plus `starvedWaitingColumns`
now covered by another worker independently. Re-measure before picking
the next one — the map drifts green as the fleet adds coverage, and I
have already caught it stale once today.
## Verification
`self-healing-stalled-card-watchdog` **10 passed** · `pnpm test:gate`
full pass · lint — green.
