- 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": "# Layering Rules\n\n## Summary\n\nThe dependency direction is fixed. Violating it is a design defect.\n\n---\n\n## Allowed imports\n\n```\ninterfaces/* -> domain/* (services, ports, models)\ninterfaces/* -> infra/adapters/* (only read-only value objects)\ndomain/* -> domain/* (same layer)\ndomain/* -> pipelines/* (call a pipeline via a port)\ninfra/adapters/* -> domain/ports/* (implement the interface)\nmain.py/init.py -> everything (composition root only)\n```\n\n## Forbidden imports\n\n```\ndomain/* -> interfaces/* (never)\ndomain/* -> fastapi/starlette (never)\ninfra/adapters/* -> interfaces/* (never)\ninterfaces/* -> infra/db/* (state lives in resources, not imports)\n```\n\n## Why\n\n- A pure domain is testable without a server, a database, or an event loop.\n- Adapters can be swapped (in-memory fake, real database) without touching\n business logic.\n- The HTTP edge stays thin and replaceable.\n\n## The port/adapter contract\n\nA **port** is an abstract class or protocol declared in `domain/<x>/ports/`.\nAn **adapter** implements it in `infra/adapters/`. The composition root binds\nthe two.\n\n```\ndomain/<resource>/ports/db.py -> repository port + document model\ndomain/<resource>/ports/service.py -> service + factory\ninfra/db/repos/<vendor>.py -> repository adapter factory\ninfra/adapters/service.py -> generic CRUD service base\n```\n\n## Enforcement\n\n- Keep every domain module importable with only the standard library and\n Pydantic. If a domain import pulls in `fastapi`, the layering is broken.\n- Reviewers (and CI) reject `import fastapi` inside `domain/` or `infra/`.\n",
