Persistent, resumable file-based memory: routed entrypoint, operational dashboard, four-layer durable memory, size discipline, supersede-don't-delete history, auto-checkpoint cadence hook, and the /bootstrap + /save-status commands. Survives context resets and /clear.
Structured reviewer-pass disciplines for code, specs, and test fixtures: review-code, review-spec, review-fixtures. Apply a fixed verification taxonomy as an executable contract, emit findings keyed to named rows/checks with severity and a verdict.
Govern a retrieval / ML eval suite as first-class code: decouple gold from the corpus surface, the L1-L8 design checklist, the failure->action loop, four coverage detectors, looseness-symmetry guardrails, and the two-lane rule.
