+# PLAN — local stdio package + safe full-API coverage
+
+Branch: `feat/local-package-and-full-coverage` (from `dev`). All PRs target `dev`.
+Flow: HEAD -> custom branch -> dev -> main. Never push directly to dev/main.
+
+Baseline (recorded Phase 0): 284 passed, 1 skipped, coverage 84.04%, threshold 80%.
+
+## Phase checklist
+
+- [x] Phase 0 — Branch from dev, baseline recorded, PLAN.md committed.
+- [ ] Phase 1 — Extract transport-agnostic core + shared tool registry.
+      - Decouple `tools/raw_tools.py` from `fastapi.HTTPException` (core ToolError).
+      - Single `registry.py` owning name -> (handler, definition, read/write, resource-type).
+      - `server.py` consumes the registry. Boundary test: importing core pulls no `fastapi`.
+- [ ] Phase 2 — stdio adapter (`stdio_app.py`) + packaging.
+      - `mcp` SDK core dep; web deps to `[server]` extra; console scripts; version 0.2.0 -> 0.3.0.
+      - stdio resolves PAT owner (`GET /user`), sets request_context once; policy+audit ON.
+      - Local audit-log fallback under user state dir.
+- [ ] Phase 3 — Resource-type-aware authorization (fail-closed).
+      - Classify repo/user/org/admin/misc from (method, path); enforce per type.
+      - admin default-deny; org membership verified; user==caller; unverifiable => deny.
+- [ ] Phase 4 — gitea_request classifier + full coverage by default.
+      - Deterministic (method, path) -> read|write with override table; unknown path => deny.
+- [ ] Phase 5 — Tests: authz matrix, write-mode bypass, classifier, stdio adapter, boundary.
+- [ ] Phase 6 — Docs & README (local vs server quickstart, authz model, packaging, CLAUDE.md).
+- [ ] Phase 7 — `.gitea/workflows/publish.yml` (uv build + publish to Gitea registry on tag).
+- [ ] Phase 8 — Verify green + coverage >= baseline, `uv build`, push, open PR into dev.
+
+## Key deltas found during orientation
+
+- No single tool registry today: definitions in `mcp_protocol.AVAILABLE_TOOLS`,
+  handlers in `server.TOOL_HANDLERS`. Phase 1 unifies them.
+- `tools/raw_tools.py` imports `fastapi.HTTPException` — the only core->web import to break.
+- Current authz is repo-only and lives in `server._verify_user_repository_access`.
+- stdio mode must run with `AUTH_ENABLED=false` (config otherwise requires MCP_API_KEYS).
+- `AGENTS.md` absent at root though CLAUDE.md cites it; create it from the contract.
