Use it to scope a\nnew build.\n\n---\n\n## Reusable as-is (do not rewrite)\n\n| Area | Artifact |\n|---|---|\n| Layering & dependency rule | the package layout and import rules |\n| Composition root | the `init.py` shape, idempotency, `get_svc` overloading |\n| Web edge | `OpenAPIFirstApp` bootstrap, handler-name = `operationId`, thin handlers |\n| CRUD slice | the four-file pattern (model / ports-db / ports-service / converters) |\n| Generic CRUD service | the base service adaptor |\n| Repository factory | base / populating / cached selection |\n| Worker | the poll loop, backoff, retry, status machine |\n| Progress bus | the bus port + in-memory adapter + streaming endpoint |\n| Human-in-the-loop | the durable pause + question document + resolve endpoint + resume map |\n| Infra adaptors | HTTP cache decorator, KV store port, LLM pool scaffold |\n| Testing | integration harness with fakes, fixture-parity pattern |\n| Docs | GSDFC + generated stubs + MCP bundle pipeline |\n\n## Template to adapt (copy, then change names)\n\n| Artifact | Change |\n|---|---|\n| `pyproject.toml` | project name, dependencies |\n| `Dockerfile` / `docker-compose.yaml` | service name, ports, services |\n| `.env.example` | connection strings, provider keys |\n| `openapi.yaml` | every path/schema/operationId |\n| `scripts/` | seed and operator tasks |\n\n## App-specific (must be authored)\n\n| Artifact | Why |\n|---|---|\n| Resource models | the business shape |\n| Repository populate/cache rules | the relationships |\n| Service business logic | domain behaviour |\n| Pipeline families (if any) | the transformation graph |\n| Pattern/rule resources | data-driven policy |\n| Fixtures & golden outputs | test data |\n\n## The two axes\n\nEverything app-specific reduces to **two axes**:\n\n1. **Resource model** — the set of resources, their fields, relationships, and\n   the OpenAPI contract.\n2. **Pipeline family** — only if inputs require multi-step transformation.\n\nIf you can specify those two axes, the rest of the app follows mechanically.\n",
