- scripts/eval-trial-series.ts stamps series_identity (eval-flake-rank's
caseSeriesIdentities) on a report's trial-outcomes JSONL as its own step,
keeping the history tool out of the paid runner's closure;
TrialOutcomeRecord gains the optional series_identity field.
- Slice-count plans let a registered trial spill into an ordinary lane when
its siblings hold every long lane, so panels never share a runner.
- Re-audited test-selection.ts (Stream B added the E2E_KINDS/BEHAVIOR_WHY
map-diff; no new module loading) and repinned its hash.
- Detach and release floors now count trial shards (66 periodic trials in
22 panels): periodic floor 33,821s, still under eval:bg:periodic's 67,380s.
- Coordination fixtures supply the executor's trial records.
