- collect.py: copy repo MCP bundles to ROOT/<name>/mcp (instead of ROOT/mcp/<name>); add nginx location guard to deny /<name>/mcp/ - config.py: bundle roots now point to <repo>/mcp and standards/mcp for static bundles - Rename core.py -> mcp_server.py and update imports in main.py and registry.py - Dockerfile: per-repo MCP COPYs under /app/<name>/mcp, drop blog copy; add ports 8008/8009 in .drone.yml - Restore standards/mcp/libraries.json from git for registry server

"docstring": "# Composition Root\n\n## Summary\n\nAll wiring happens in exactly one module. It builds a **flat resource\nregistry** and exposes it to the HTTP layer and to scripts.\n\n---\n\n## The resource registry\n\n`init.py` returns a plain `dict[str, Any]`. Keys follow two conventions:\n\n- `<resource>_repo` — a repository adapter for a resource.\n- `<resource>_svc` — a service for a resource.\n\nPlus named infrastructure adaptors:\n\n- `http_cache_store` — response cache backend.\n- `progress_bus` — progress/event bus.\n- `<vendor>_<kind>` — fetchers, clients, stores.\n\nThe API stores the dict on `app.state.resources` during lifespan startup.\nHandlers read from it; nothing imports concrete adapters.\n\n## Shape\n\n```python\n_resources: dict = {}\n_initialized = False\n\nasync def init(settings=None) -> dict:\n global _initialized\n if _initialized:\n return _resources\n\n await setup_database(uri=settings.mongo_uri, db_name=settings.mongo_db)\n\n # 1. leaf repositories\n user_repo = create_user_repo()\n\n # 2. dependent repositories (dependencies passed by keyword)\n wallet_repo = create_wallet_repo(user_repo=user_repo)\n\n # 3. services (build via the DI library, injecting the repo)\n _resources[\"user_repo\"] = user_repo\n _resources[\"wallet_repo\"] = wallet_repo\n _resources[\"user_svc\"] = get_user_service(user_repo)\n _resources[\"wallet_svc\"] = get_wallet_service(wallet_repo)\n\n # 4. infrastructure adaptors (optional)\n _resources[\"http_cache_store\"] = HttpCacheStore(...)\n _resources[\"progress_bus\"] = ProgressEventBus()\n\n _initialized = True\n return _resources\n\nasync def shutdown() -> None:\n global _initialized\n await close_stores(_resources)\n await shutdown_database()\n _resources.clear()\n _initialized = False\n```\n\n## Typed accessors\n\nExpose a `get_svc(name)` helper with one `@overload` per key so scripts get\ntyping without importing concrete classes:\n\n```python\n@overload\ndef get_svc(name: Literal[\"user_svc\"]) -> UserService: ...\n@overload\ndef get_svc(name: Literal[\"wallet_svc\"]) -> WalletService: ...\n\ndef get_svc(name: str):\n return _resources[name]\n```\n\nAlso expose `get_db()` (raw database handle) and pure helpers such as\n`compute_fingerprint(payload)` (canonical hash used for deduplication).\n\n## Rules\n\n- `init()` is **idempotent**.\n- The composition root is the only place that imports concrete adapters.\n- Handlers never call `init()`; they read `request.app.state.resources`.\n- Scripts call `init()` / `shutdown()` around their work.\n",
