CLI UX: TTY color, recursive directory input, roll-up summary line, and wald check --llm progress. pyright is now a hard CI gate. Temporal-shuffle evasion triage (4 shapes accepted). selection-survivorship-cohort parked for narrative fusion. Golden byte-identity test. Composite GitHub Action (action.yml) emitting SARIF for PR annotations, inputs passed via env to avoid command injection.

No detector behavior change — four static classes still precision 1.00 / recall 1.00 on 192 mutants, 0.0% FP on 83 clean notebooks. Full notes in CHANGELOG.md.
