A human reviewer's feedback was being thrown away.
`PrCommentHandler.handleChangesRequested` gated on `task.column !==
"in-review"` and returned early. On any board whose review lane is
renamed, a GitHub **"changes requested"** review produced **no steering
comment** and the card **never went back to work** — the feedback
vanished behind a log line nobody reads. No error, no audit row.
## Census
| file | main | here |
| --- | ---: | ---: |
| `packages/engine/src/pr-comment-handler.ts` | 1 | **0** |
## Two literals, only one countable — again
```ts
if (task.column !== "in-review") { … return; } // counted
…
await this.store.moveTask(taskId, "in-progress"); // INVISIBLE to the census
```
The census scores comparisons. The requeue **destination** is a call
argument, so nothing in the backlog pointed at it — the same pairing as
the branch-worktree auto-requeue in #2797, and the same trap: converting
the gate alone would make the handler *admit* the review and then
attempt a move into a lane the board may not declare, which `moveTask`
rejects. A half-conversion here turns a silent drop into a thrown
rejection. They convert together or not at all.
That is now the second confirmed instance of this shape. The pattern to
look for is a **counted guard whose body performs a hardcoded
`moveTask`** — the guard is the visible half and the move is the
dangerous one.
## Revert results (measured, each run independently)
| conversion | reverted → |
| --- | --- |
| review-lane gate | RENAMED case fails — `updateTask`/`moveTask` never
called; the review is dropped |
| requeue destination | RENAMED case fails — `moveTask` called with
`"in-progress"` instead of the board's wip lane |
The legacy case passes both ways, which is why both vocabularies run. A
non-vacuous companion (renamed board, card sitting in the hold lane)
keeps a gate that admits everything from passing.
## Verification
- `pnpm test:gate` — 161 + 487 + 13 + 71, green
- `pr-comment-handler.test.ts` — 34 passed
- `npx tsc -p packages/engine/tsconfig.json --noEmit` — clean
- `pnpm lint` — clean
- `node scripts/lifecycle-column-census.mjs --strict` — exit 0
(Running the census explicitly, not just `pnpm lint`: CI's Lint job runs
both, and a clean local `pnpm lint` is **not** evidence the Lint check
passes — that cost a round-trip on #2797.)
