**Step 8: Verification (only when `$VALIDATE_MODE`)**

Skip this step entirely if NOT `$VALIDATE_MODE`.

For every item merged in Step 7 (status still `pending`, a real `commit` was
recorded by the merge) that has not yet been verified:

re-derive the status vocabulary inline):

**Route via `quick-batch verification-routing`** (wraps
`routeVerificationOutcome`, `src/quick-batch-dispatch.cts` — the single
source of truth for this routing, never re-derived inline):
```bash
QB_VERIFY_ROUTE_JSON=$(gsd_run quick-batch verification-routing --status "$STATUS" --raw)
```

| `action` | Meaning | What this step does |
|---|---|---|
| `complete` | `STATUS == "passed"` | Proceed to Step 9 for this item — `quick-batch complete` is called there. |
| `human_needed` | Verifier flagged manual review | **Terminal for this item.** Do NOT call `quick-batch complete` — no STATE row is appended (row 30). Display the items needing manual check; continue with the rest of the batch. |
| `fail` | `STATUS == "gaps_found"` (or `missing`/`unknown`/`stale` — anything the query could not resolve to a real answer) | Mark the item `failed` with the routing's `failureReason`. NO automatic gap-fix retry (v1 exclusion), NO rollback of the already-merged commit (row 31/34). Continue with the rest of the batch. |

An item this step marks `human_needed` or `failed` is NOT reverted — its
worktree was already removed by the successful merge in Step 7 (verification
runs post-merge, unlike a `merge_failed`/`scope_violation` routing, which
never reaches this step because the item never merged).

Continue to Step 9 once every merged item has been verified (or explicitly
routed to `human_needed`/`failed`).
