+# Release & Distribution Runbook (v1.4.0+)
+
+The code side of a release is fully automated; three account-bound steps need
+a human once, plus the directory submissions. Track them here.
+
+## One-time setup (owner action)
+
+- [ ] **PyPI trusted publisher** — on <https://pypi.org/manage/account/publishing/>
+  add a *pending publisher* for project `autocad-mcp-pro`:
+  repository `U-C4N/Autocad-MCP`, workflow `release.yml`, environment `pypi`.
+  (No API token is stored anywhere; `release.yml` uses OIDC.)
+- [ ] **GitHub environment** — create the `pypi` environment in the repo
+  settings (Settings → Environments) so the publish job can bind to it.
+- [ ] **MCP registry login** — install `mcp-publisher`, then
+  `mcp-publisher login github` (authenticates the `io.github.u-c4n` namespace).
+
+## Every release
+
+1. Bump `pyproject.toml` + `server.json` versions, add the CHANGELOG section,
+   update the README snapshot line — `tests/test_release_consistency.py`
+   enforces all of it.
+2. Push `main`, wait for CI to go green (lint, linux, windows, package,
+   docker, registry-validate).
+3. Tag and push: `git tag v1.4.0 && git push origin v1.4.0`.
+   `release.yml` runs the test gate, verifies tag == package version, builds,
+   publishes to PyPI via trusted publishing and cuts the GitHub Release.
+4. Verify: `pip install autocad-mcp-pro==<version>` in a clean venv;
+   `uvx autocad-mcp-pro --help`.
+5. Publish the registry manifest: `mcp-publisher publish` (validates
+   `server.json`, checks the `mcp-name` marker in the PyPI README).
+
+## Directory listings (submit once, then keep fresh)
+
+- [ ] Glama — <https://glama.ai/mcp/servers> (auto-indexes GitHub; claim the
+  server page and verify metadata).
+- [ ] mcpservers.org — submit via their GitHub repo PR flow.
+- [ ] awesome-mcp-servers — PR adding the server under CAD/engineering.
+- [ ] Smithery — optional; requires a `smithery.yaml` (evaluate demand first).
+
+## Benchmark refresh (per release)
+
+```bash
+python -m benchmarks.run_competitors --server autocad-mcp-pro --backend ezdxf
+python -m benchmarks.run_competitors --server puran-water-autocad-mcp --backend ezdxf
+python -m benchmarks.run_competitors --server beiming183-autocad-mcp --backend ezdxf
+# sanitize + copy reports into benchmarks/results/published/, then:
+python -m benchmarks.render_live_chart
+```
+
+Bump the competitor pins in `benchmarks/competitors.yaml` deliberately (new
+SHA = re-read their tool contracts before trusting the mappings).
