+# Audit — 2025-09-17
+
+Summary
+- Scope: Repo structure, governance compliance, plan alignment, CI/containers, TDD, zero-debt.
+- Status: Mostly compliant; a few gaps noted with fixes proposed or applied.
+
+Findings
+- Governance
+  - One-way Q→P→Plan: compliant.
+  - Read `.llm.md`/write both: compliant in artifacts; continue practice.
+  - TDD: present; tests for CLI/guardrails/new-mode exist; proceed to cover remaining milestones.
+  - Zero debt: generally compliant; architecture doc added now to satisfy plan; keep docs/tests in lockstep.
+  - Clean root: compliant; marker removed; heuristic detection in place.
+  - Planning/architecture: docs/architecture.md added; maintain ADRs if decisions evolve.
+  - CI/containers: Gitea workflow + Docker Compose present; local parity script present.
+- Repo Structure
+  - Organized under `collab/`, `docs/`, `prompts/`, `modes/`, `templates/`, `scripts/`, `meta/`, `.gitea/` — clean.
+- Scaffolding Templates
+  - Added project CI/Docker templates and AGENTS.md. Missing: project `.gitignore` and `scripts/test.sh` template (recommended; add).
+- Tests
+  - Repo tests pass (internal runner). Add Docker test run to CI already configured.
+- Open Work vs Plan
+  - Pending: `new-project`, `run`, config precedence (`yq`), copying templates, `.gitignore` template, project scripts/test.sh.
+
+Actions
+- Add templates/project/_shared/{.gitignore,scripts/test.sh} [recommended ASAP].
+- Implement remaining milestones via TDD; expand tests accordingly.
+- Keep DevLogs updated for each change.
