Next entry from the verified coverage map on #3115 — and the first one
whose failure mode is **irreversible**.
## The gap
`reclaimArchivedColumns` was uncovered: blinding it back to the id
`archived` leaves all 825 self-healing tests green, because no fixture
in this suite puts a card in a renamed archive lane.
## Why it matters more than the other 22
That guard **skips** archived cards — their branches belong to archive
cleanup, not to branch reclaim. Keyed on the id, a card filed in a
renamed archive lane fails the skip, and this sweep reaches:
```
git branch -D "fusion/<id>"
```
Every other uncovered resolver I have pinned so far causes a wrong
lifecycle decision — a card not requeued, a lease not released, a
diagnostic not surfaced. All of those are recoverable from the task row.
**A deleted branch is not.**
## Measured
415 pass. Blinding `reclaimArchivedColumns` fails exactly this case, and
the assertion that fails is the one checking `git branch -D` was never
called — so the failure *is* the branch being deleted, not a proxy for
it.
## Progress on the map
Closed so far: `archiveStaleDoneTasks` ×2 (#3115),
`reconcileOrphanedPendingStepResults` (#3090),
`recoverDriftedAgentTaskLinks` (#3102), `reconcileTaskWorktreeMetadata`
wip (#3132), `reconcileDependencyBlockingLeases` ×2 (#3138), and this
one. **22 uncovered resolvers remain.**
Every sweep probed so far has been uncovered, and one
(`reconcileDependencyBlockingLeases`) was only half-covered by its own
first test — the branch short-circuited before the second resolver was
ever consulted. That is why I now blind each resolver separately rather
than trusting a single revert.
Next: `reconcileInReviewBranchRebind` (rebinds branches of live cards)
and the two remaining `reconcileTaskWorktreeMetadata` resolvers
(terminal, review).
## Verification
`self-healing.test.ts` **415 passed** · `pnpm test:gate` 13 + 161 + 487
+ 71 · lint — green.
