## The FN-4000 consistency reconciler failed in *both* directions
`findTaskStateInconsistencies` keyed both checks on legacy lane
literals, and they break in opposite ways:
```js
const hasDoneTransient = task.column === "done" && (status failed || error || worktree || blockedBy || …);
if (task.status === "failed" && task.column !== "in-review") { … }
```
| check | on a renamed board | effect |
| --- | --- | --- |
| `hasDoneTransient` | **never fires** | a finished card still holding
`status:"failed"`, a worktree, a blockedBy or live recovery counters is
never reported and never normalized — precisely the stale state FN-4000
exists to clear |
| `failed-status-outside-in-review` | **fires for every failed card** |
no column equals the literal, so the report lists the whole board |
The second is the more dangerous of the two: a tool that reports nothing
looks broken, but a tool that reports everything looks like it is
working.
## Wiring, and why the resolver is injected rather than built inline
Lanes are resolved **per task** (a board can span workflows) and passed
in. Resolving inside the loop would drag `importCore()` — and therefore
a built `packages/core/dist` — into every unit test of a pure
reconciliation loop.
`main` wires the real resolver whenever it opened a real backend, so
this is **not** the inert optional-parameter shape this migration keeps
finding. A caller injecting its own store (tests) has no staged dist and
falls back to the documented legacy literals, which is exactly today's
behaviour.
`importCore` is now exported from `scripts/lib/backend-db.mjs` so
operator scripts reach core helpers through the **same staged-dist seam
`openBackend` already uses**, rather than each growing its own dist path
— `@fusion/core` is not resolvable from repo-root `scripts/`, which is
what made the obvious import fail.
The normalization move now targets the card's **own** column: naming
`"done"` was only ever a way of spelling *"where it already is"*, since
the move exists to trigger the store's done-normalization.
## One of my test expectations was wrong before the code was
My first version asserted that a card in a renamed complete lane with
`status:"failed"` yields only the transient-state finding. It yields
**both** — and that is correct, because a failed card outside the review
lane genuinely is flagged. I isolated the case (dropping
`status:"failed"`, keeping the worktree) so it pins one behaviour
instead of blurring two, rather than "fixing" the expectation to match
whatever came out.
## Revert proof
Restoring the four literals:
```
✖ reports stale transient state in a RENAMED complete lane
✖ does NOT flag a failed card that is sitting in the board's own review lane
✖ runReconciliation normalizes a renamed complete lane by moving the card to its OWN column
ℹ pass 5 ℹ fail 3
```
The remaining two new cases pass both ways by design — "still flags a
failed card outside the resolved review lane" and "unresolved lanes keep
exactly the legacy behaviour" guard against over-correction, so I am not
counting them as coverage of the defect.
## Verification (measured)
- `node --test` — **8 passed / 0 failed** (3 pre-existing + 5 new)
- sibling script suites (`recover-stale-blocked-by`,
`reconcile-leaked-soft-deletes`) — **7 passed**, unaffected by the
shared-lib export
- `node --check`, `eslint` — clean
- `lifecycle-column-census --strict`, `check-sql-column-literals`,
`check-lane-wiring`, `check-fnxc-future-dates` — green
No changeset: root `scripts/` is repo tooling, not part of the published
package.
## Still not addressed in this territory
`reconcile-leaked-soft-deletes.mjs` carries a raw `UPDATE
project."tasks" SET "column" = 'archived'` — on a renamed board that
writes a column the workflow does not declare, creating the
undeclared-column state this migration keeps repairing elsewhere. It
holds a raw backend rather than a store, so it needs the same
`importCore` seam this PR exports; left for a follow-up rather than
bundled here.
