Next two entries from the verified coverage map on #3115.
`reconcileDependencyBlockingLeases` had **both** of its resolvers
uncovered — blinding either `leaseWipColumns` or `leaseHoldColumns` back
to its legacy id left all 825 self-healing tests green, because every
fixture in that block uses `in-progress` / `todo`, where the literals
happen to be correct.
## What the literals cost
The holder scan matches no card **and** the dependency scan matches no
card. A stale file-scope lease blocking a real dependency is never
rebounded, so the dependent stays `overlapBlockedBy` behind a holder
that is not coming back. That is the deadlock this sweep exists to break
— silently not broken, no error, no log.
## Two cases, because one did not cover both — measured, not assumed
My first case (holder in a renamed wip lane, dependency marked
`overlapBlockedBy`) pinned `leaseWipColumns`. I then blinded
`leaseHoldColumns` against it and **it stayed green**.
The reason is in the control flow: the `overlapBlockedBy === holder.id`
branch short-circuits and `break`s **before** the hold membership is
consulted. So that fixture can never reach the guard `leaseHoldColumns`
feeds.
The second case drops the marker, leaving an unmarked dependency resting
in a renamed hold lane, which falls through to the
overlapping-hold-dependency branch.
| blinded | result |
|---|---|
| `leaseWipColumns` | **1 failed** |
| `leaseHoldColumns` | **1 failed** |
Before the second case, that table read `1 failed` / `still green`.
Checking each resolver separately is the only reason I noticed — a
single "the suite fails when reverted" would have looked like proof and
covered half the conversion.
## Remaining
23 uncovered resolvers on the map. Next by risk:
`reclaimStaleActiveBranches` (deletes branches) and
`reconcileInReviewBranchRebind` (rebinds branches of live cards), both
needing a git-shelling harness.
## Verification
`self-healing.test.ts` **415 passed** · `pnpm test:gate` 13 + 161 + 487
+ 71 · lint — green.
