+# Application Template
+
+A minimal, runnable skeleton of the standardized architecture. It demonstrates
+both axes of the blueprint (see `standards`):
+
+1. **Resource axis** — items and jobs, each a Claude-style generic CRUD slice
+   (model → document → repo → service → route), all driven from `openapi.yaml`.
+2. **Pipeline axis** — a background `worker.py` that polls pending jobs and runs
+   `pipelines/item_sync.py`, a deterministic async step chain.
+
+Everything here is deliberately small so an agent can rewrite each file rather
+than delete unused code. The domain is a neutral "item", not an app noun.
+
+## Instantiate a new app
+
+    cp -r templates/app apps/<your-app>
+    cd apps/<your-app>
+
+1. `pyproject.toml` — rename the package; keep the internal library pins.
+2. `config.py` — replace/add settings consumed by your domain.
+3. `openapi.yaml` — replace the `Item`/`Job` resources with your resources.
+4. `domain/` — rename `item` and `job` slices to your aggregates.
+5. `pipelines/item_sync.py` — replace the demo steps with your pipeline.
+6. `tests/` — keep the two test files as the pattern for your own.
+
+Run the API:
+
+    pip install -e ".[dev]"
+    uvicorn main:app --reload
+
+Run the worker:
+
+    python worker.py
+
+## What to keep, what to replace
+
+| Keep                         | Replace / rename                      |
+|------------------------------|---------------------------------------|
+| `config.py` shape            | Settings fields                       |
+| `init.py` wiring pattern     | Resource names                        |
+| openapi-first routing        | Paths, schemas, operationIds          |
+| mongo-ops repo factory       | Collections, doc models               |
+| generic CRUD adaptor         | Nothing (reuse as-is)                 |
+| worker poll + status loop    | Job payloads, pipeline steps          |
+
+## Where the internal libraries slot in
+
+- `openapi_first.app.OpenAPIFirstApp` — main.py, interfaces/openapi.py
+- `mongo_ops` — infra/db/setup.py, infra/db/repos/mongo.py, domain/*/ports/db.py
+- `hexa.build` — domain/*/ports/service.py
+- `dagpipe` — pipelines/ (wrap step chains in a DAG once they branch)
+
+Confirm current endpoints and ownership with the `standards` registry MCP tool:
+`find_library("pipeline")`, `find_library("auth")`, etc.
