## An audit that scanned four legacy lanes — and claimed it had
Two halves of the same wrong answer.
**The query allowlisted the lanes:**
```sql
WHERE deleted_at IS NULL AND "column" IN ('triage','todo','in-progress','in-review')
```
On a board whose lanes are named anything else that matches **nothing**,
so the audit scans zero rows and reports zero contamination — a clean
bill of health from a scan that never happened. `triage` is in that list
too, a lane U11 (#2515) deleted.
**And the report asserted the coverage it did not have:**
```js
scannedColumns: ["triage", "todo", "in-progress", "in-review"],
```
printed regardless of what the query returned. When I first surveyed
this script I called that field "the one thing keeping it from being
fully silent" — it turns out it was a **claim, not an observation**, so
it was not keeping it honest at all. It is now derived from the rows
that came back.
## Fix: exclude finished lanes instead of allowlisting active ones
Inverted so the default is the safe one — an unrecognised lane is active
work by assumption and **is** audited; only lanes that genuinely mean
finished drop out. An allowlist fails **closed** (skip everything
unknown), a denylist fails **open** (look at it), and for an audit one
extra finished branch is a far smaller error than auditing nothing.
Filtered in JS rather than by building a dynamic SQL exclusion: it keeps
**one** place deciding what "finished" means, and removes the last
raw-SQL lane literal from this file.
## Revert proof
```
✖ scannedColumns reports the board's real lanes, not a fixed legacy claim
✖ reports each scanned lane once, and nothing at all for an empty board
ℹ pass 1 ℹ fail 2
```
## A demonstration of #3000, for free
This PR removes a 4-literal raw-SQL clause, and
`check-sql-column-literals` here reports **22, unchanged and green** —
because this branch predates #3000 and the gate still walks `packages/`
only. That is precisely the blind spot #3000 closes, reproduced a second
time.
## Merge order
This removes the 4 literals #3000 baselines. Landing this **after**
#3000 drops that count and its gate fails on DECREASE — that gate
auto-rewrites the baseline and asks for the commit, unlike
`check-lane-wiring` which needs an explicit `--update-baseline`. Either
order works; one of them needs a re-record, and I am happy to push it.
## Verification (measured)
- `node --test` — **3 passed / 0 failed** (1 pre-existing + 2 new)
- `node --check`, `eslint` — clean
- `lifecycle-column-census --strict`, `check-lane-wiring`,
`check-fnxc-future-dates` — green
No changeset: root `scripts/` is repo tooling, not part of the published
package.
## Territory status
This was the last item I know of in `scripts/`. The four operator
scripts holding lane assumptions — `recover-stale-blocked-by` (#2992),
`reconcile-task-state-consistency` (#2994),
`reconcile-leaked-soft-deletes` (#2999) and this one — are now either
resolved or, where a script genuinely cannot resolve lanes, made loud
rather than silent.
