Add lib page 11 (SemVer contract, pre-1.0 rule, tag==version invariant, Keep a Changelog), the releasing wiki runbook, and canonical release templates (CHANGELOG.md, VERSION). Vendor them into the MCP bundle as templates/release + release.json and expose registry://release with list/get tools. Add a changelog component to the app template. Enforce the tag<->version contract in both Drone shapes: Type A check-version and the backfill loop verify pyproject version; Type B adds a VERSION guard step.
Document the two `.drone.yml` shapes used across the org, derived from the
repos:
- Type A `python-lib.yaml`: build-and-publish-pypi + backfill-pypi-from-tags
- Type B `service-docker.yaml`: build-and-deploy-service + build-and-deploy-site
- add reference page `10_drone_pipelines`
- vendor `src/templates/drone/` into the MCP bundle (`drone.json`)
- expose `registry://drone` + `list_drone_templates` / `get_drone_template`
- wire `build.py` to vendor drone templates; rebuild nav/index (14 modules)
- serve the pinned auth-server OpenAPI contract as the standards MCP resource docs://spec (no auth-server MCP bundle)
- add Auth Integration recipe (14) and wire it into the registry, prompts, index, and nav
- un-defer Auth Server in the library registry (spec/recipe pointers)
- ship the opt-in template auth slice: interfaces/auth/ (placeholder + mergeable bearerAuth security.yaml) and AUTH_SERVER/JWT_SERVER env
- rebuild bundle (13 modules, 44 components); template stays authless by default
