Full dual-flywheel audit — Learning (capture from review) + Pruning (remove dead rules). Periodic charter hygiene.
One-time initial charter scaffold — detect stack, seed state, scaffold idioms, classify sensors, build the globs index.
Run the drift sensor on the current diff — fast pre-verify check that loaded charter rules still match what the code is doing.
Triage the code-debt ledger — review the debt sensor's findings and update corpus/state/code-debt.md.
Regenerate .keystone/INDEX.json — the primitive descriptor index every agent reads at session start.
Capture a learning candidate (surprise, incident, review finding) into .charter/learning/inbox/ for later synthesis.

Phase 1 of the six-phase lifecycle. Forces the agent to write down what "done" looks like before any code is touched. Output lands in the task notes / PR description / equivalent — acceptance criteria the agent and user both sign off on.
