## Regles
- Toujours lire les logs complets avant de diagnostiquer
- Ne pas confondre: erreur intermittente vs erreur structurelle
- Si `dependency-review` echoue seul → ignorer (connu, GitHub Advanced Security)
- Si `container-scan` / `codeql` echoue seul → verifier si intermittent
- Toujours proposer une verification locale
Force a full-file rewrite (Write) instead of patch (Edit) when Edit keeps failing or diff is large. Context rot mitigation — use when Edit has failed ≥2× on same file, or when estimated diff >30% of file size.
STOA PR Guardian — advisory three-axis review (ADR compliance, security, AI code smell) with binary GO/NO-GO verdict + confidence. Never approves, never blocks merge.
Analyze cycle capacity gap and propose backlog items to fill the sprint to ~80% of proven velocity.
Visual roadmap snapshot — theme progress, milestones, velocity. Zero new infra (Linear MCP + velocity.json).
Cycle-aware bidirectional sync between plan.md and Linear. Discovers all cycle tickets, detects drift, updates markers.
Run 8-persona Council validation on a feature/ADR, then auto-create a Linear ticket if score >= 8/10.
