I converted this in #3110, the parity gate failed, and I reverted it.
**The gate was right** — and the reason was subtler than "one encoding
moved". Knowing it is what makes this conversion possible.
## Why the first attempt failed
My version hoisted the comparison onto a local:
```ts
const pgRowColumn = String(pgRow.column ?? "");
const rowIsArchivedLane = archivedLanes ? archivedLanes.has(pgRowColumn) : pgRowColumn === "archived";
```
That gate's TS scan keys on the **property** being named `column` —
deliberately, because the receiver is variously `task`, `row`, `dep`,
`t`. Losing the `.column` access dropped the TS count while SQL and raw
held steady, which it reads as divergence.
**Behaviourally identical, structurally invisible.** Same failure mode I
hit from the other direction in #3163, where I collapsed a Drizzle
fallback into a string array.
## The fix
Keep `pgRow.column === "archived"` **verbatim** as the fallback; add the
resolved path in front of it. No encoding's count moves, an unwired or
degraded caller behaves exactly as before, and the gate is **satisfied
rather than worked around** — the same additive shape as the six Drizzle
LANE sites (#3160, #3162, #3163).
## What it fixes
A LANE question: *"is this row in the board's archive lane, so logging
is read-only?"*
Against the literal, a card the operator filed away on a renamed board
kept **accepting log writes** — new activity accruing on closed work.
`deletedAt` covers the soft-delete half, which is why the gap is narrow
and why it stayed invisible: the common path is soft-delete.
## The recorded omission is retired properly
`log-entry-archived-lane-gate.test.ts` carried the renamed case as a
**deliberate omission** with its reason. It is now the first case in the
file, and the note explains why the earlier judgement changed rather
than quietly disappearing — a deferral that vanishes without explanation
is how the next reader loses the thread.
## Measured
- **3/3** in that file (renamed case added); parity test **2/2**,
inventories unmoved.
- **MUTATION**: dropping the resolved branch fails the renamed case and
leaves the legacy **control** and the live-lane **negative** green.
- log-entry / archived / audit suites — **3 files / 9 tests pass**.
- `tsc --noEmit -p packages/core` clean; census `--strict`,
`check-sql-column-literals` clean.
- `check-fnxc-future-dates` is red on `main` from `task-update.ts`
(another lane's stamps), not from these files.
## Census
**Unchanged** — the literal remains the fallback arm, by design.
