 # Changelog
 
+## [1.91.371.0] - 2026-10-31
+
+**A PR push in a repository with a merge train no longer waits ten minutes for a check that does no work.** Under a train policy every PR push runs E2E Evals in `pr-summary` mode, which plans no paid slices, yet its `readiness` job still waited out the 600-second quiet window and green Free Tests before the run could finish. Now `readiness` waits for `route` and skips in `pr-summary` mode, so E2E Evals on a PR push finishes in about a minute (58 s on #3609) instead of after the 10-minute wait.
+
+### Changed
+- **`.github/workflows/evals.yml`**: `readiness` needs `route` and runs only when the mode is not `pr-summary`. In `pr` mode (a repository without a train) it still gates recovery and planning as before. In `pr-summary` mode a red Free Tests now shows on Free Tests alone, which stays the required free check; the train gate and the dispatched screen still carry the paid work.
+- **`bun run test:health`**: the "PR lane push-to-verdict" rule text says `pr-summary` runs skip the wait since GSTA-149, so its p50 drops by about 10 minutes from this change on.
+- **docs/TESTING_INTERNALS.md** describes the skip.
+
+### Tests
+- `test/evals-pr-lane-workflow.test.ts` pins `readiness.needs` and the full `if`. `test/evals-train-workflow.test.ts` checks that a `pr-summary` push runs only `build-image`, `route` and `screen-summary`, and that `pr` mode still runs `readiness`.
+
 ## [1.91.370.0] - 2026-10-31
 
 **The free suite now runs on `ubicloud-standard-2` instead of `ubicloud-standard-8`, at the same 20 shards, for about a quarter of the runner cost.** Each shard runs its files one at a time, so it waits on disk and processes rather than CPU. In three paired rounds at one commit, the median per-shard time rose by 3 to 8 s, inside the round-to-round spread of −90 to +65 s, while runner-minutes stayed about equal (464 vs 475). Peak memory stayed under 2.5 GiB and free disk above 15 GiB. A 16-shard arm was slower beyond that spread, so the shard count stays at 20.
