 ### Changed
 - **Gate integrity (a gate edit):** harness, INFRA, INCOMPLETE and unattributed reds never rerun and are never flaky. Neither is a case already red twice, or a case whose rerun could not turn the gate green. No threshold, trial count, case kind, judge model, `EVAL_POLICY` constant or `HARNESS_VERSION` changed (recorded non-behavioral). Pass-rate history still records each run's first execution unchanged; a rerun's trials stay in its `paid-rerun-*` artifacts and the flake record. On the gate lane, a rule shard that ran to completion with a red case no longer fails its slice job. The report still fails closed on it, so the run's conclusion follows the report and a flaky GREEN run concludes `success`. Execution failures (timeouts, runner errors, hollow or unfinished shards) still fail the slice. Train gates take the same rerun path. A bisect reruns a VERDICT FAIL once on its prefix (`scripts/train-gate.ts`), and a pass there is a flaky PASS naming both runs. The PR comment's verified-summary check also bounds `flakyCollectorFailures`, so a failed collector record that is not a flaky case still fails the comment. Negative control for the slice-exit change: a case red on its first run and red again on its rerun keeps the real report CLI at exit 1 and `VERDICT RED`; `slices-report` still runs after every rerun path and its last step fails the job on reconcile exit 1, no job carries `continue-on-error`, so the run concludes `failure`; the binding is RED and `gate-reuse` refuses it; and the train record is RED, which T1 classifies RED whatever the run concluded (`test/paid-rerun.test.ts`, `test/evals-train-workflow.test.ts`).
 - **Free regressions:** `test/paid-rerun.test.ts` replays a trimmed capture of run 39293281037 through the real `--report` and `--rerun-plan` CLI. Its negative controls cover red twice, harness, INCOMPLETE and checkpoint reds, a new red on a later attempt, a first-attempt pass, rerun results with a missing or mismatched manifest, and reruns of unplanned cases. `test/gate-reuse.test.ts` covers R2a and R2 reuse of a flaky GREEN, a manual-attempt binding, and a run still red after its rerun. `test/train-gate.test.ts` covers the train record and the bisect rerun. Workflow wiring tests are in `test/evals-train-workflow.test.ts` and `test/ci-paid-coordination.test.ts`.
+- **Rerun artifact layout:** the first gate of this change (run 39363705692) reran its one red case and passed, but `download-artifact` unpacked the lone `rerun-plan-a1` match into the report root, over the plan's own `manifest.json`, so the report read every case as unplanned and stayed red. The plan artifact now holds `rerun-plan-a<attempt>/manifest.json`, rerun results download under `reruns/`, the rerun logs artifact is `rerun-logs-*` so it no longer matches `paid-rerun-*`, and the report finds the rerun manifest in either layout `download-artifact` produces. That run's artifacts, replayed in the new layout, report `VERDICT GREEN` with `FLAKY 1`.
