A lane literal the census cannot see — it is a **call argument**, not a
comparison — and the two sibling hooks disagree about how to record the
same kind of fact:
```ts
onTaskMoved: async (task, fromColumn, toColumn, ctx) => {
await store.enqueueSyncAsync({ …, toColumn }); // the real column
},
onTaskCompleted: async (task, ctx) => {
await store.enqueueSyncAsync({ …, toColumn: "done" }); // ← a guess
},
```
On a board whose complete lane is named anything else, the sync-queue
row names a column that board does not have.
## Why fix a field nothing reads
`toColumn` is written to `ce_pipeline_sync_queue` and **never consumed
by any logic** — I checked every reference; it appears only in the
schema, the store's insert, and the row type. It is audit metadata.
That is both why it went unnoticed and why it is worth one token: the
single thing a wrong audit row costs you is the ability to reconstruct
what happened after the fact. A queue that says a card went to `done` on
a board with no `done` is worse than a queue with no column at all,
because it reads as authoritative.
## Structural ratchet, and I would rather say so than imply otherwise
`getCePipelineStore` requires a live PostgreSQL `AsyncDataLayer` and
throws without one, so driving the hook means standing up PG to
re-assert a one-token substitution — against the standing rule on slow
tests. The repo already takes this trade in the same shape
(`packages/core/src/__tests__/analytics-timing-roles-resolved.test.ts`,
whose analytics aggregators have the identical problem).
The test comment states plainly what it does and does not prove: it pins
that the hook reads the card's own column and holds no completion
literal; it does not exercise the write.
Comments are stripped before the negative assertion — the test's own
explanation names the old literal, and a ratchet that matches its own
prose passes forever without checking anything. (That mistake is already
in this program's history, which is why it is guarded here.)
## Revert proof (measured)
Restore `toColumn: "done"` — **both** assertions fail (the positive one
on the missing `task.column`, the negative one on the literal).
## Verification
- `pnpm test:gate` — 161 / 487 / 13 / 71 passed
- `pnpm lint` — clean
- `tsc --noEmit` (`@fusion-plugin-examples/compound-engineering`) —
clean
- full plugin suite — 319 passed across 32 files

## Summary by CodeRabbit
* **Bug Fixes**
* Sync audit records now capture the task’s actual completion lane
instead of assuming it is named “done.”
* Improved audit accuracy for boards with custom completion lane names.
* **Tests**
* Added coverage to verify completion records use the task’s real
destination lane.
