 | D-140 | MCP server extensibility = plugin-registry (`plugins/<name>.py` implementing `register(mcp)`). | Future capabilities (new scanners, policy evaluators, cost tools) drop in as new plugin files — no `server.py` edits. `server.py` scans `plugins/` and calls `register` on each. This is the extensibility insurance: plugins are decoupled from the server entrypoint. | P5 implements the plugin-registry; initial plugins are `principles.py` + `validation.py`. |
 | D-141 | PPTX storage = commit binary directly to `docs/presentations/` (no LFS). | Decks are small (~1-5 MiB); git handles binary blobs. LFS requires server-side support (unverified for git.cloudinit.dev) + client config. Committing directly is simplest and works without any repo/server config. Binary diffs are not delta-friendly, but deck changes are infrequent. | P1/P2/P6 commit .pptx directly. |
