# P53 Phase 3 Candidate Evidence Audit

## Goal

Audit the Phase-3 candidate tracks from P52 and record which track should come
first. This is a decision/audit step, not implementation.

## Scope

- Add `specs/p53-phase-3-candidate-evidence-audit.spec.md`.
- Add a Phase-3 candidate evidence audit section to `docs/MIND-MODEL-DESIGN.md`.
- Update `AGENTS.md` and `CLAUDE.md` inventories.
- Do not change runtime code.

## Steps

- [x] Capture P53 task contract.
- [x] Document candidate readiness and blockers.
- [x] Update agent inventories.
- [x] Run spec and grep acceptance checks.
- [ ] Commit, ingest decision memory, push, and open PR.

## Verification

```bash
agent-spec parse specs/p53-phase-3-candidate-evidence-audit.spec.md
agent-spec lint specs/p53-phase-3-candidate-evidence-audit.spec.md --min-score 0.7
