It never names a concrete\n> business domain. Any application — expenses, health metrics, inventory,\n> analytics — is produced by filling in **two axes only**: the resource model\n> and (if needed) the pipeline family.\n\n## How to read this\n\n| Page | What it covers |\n|---|---|\n| Overview | The philosophy and the one-way dependency rule |\n| Layering Rules | Which package may import which |\n| Composition Root | The single wiring point |\n| Spec-First Routing | OpenAPI as the source of truth |\n| CRUD Template | The canonical resource slice |\n| Pipeline Scaffold | Data-driven processing families |\n| Worker & Progress | Async jobs, status machine, streaming progress |\n| Human-in-the-Loop | Pausing a job to ask a question |\n| Infra Adapters | MongoDB, cache, stores, LLM, mail |\n| Testing | Integration + unit conventions |\n| Build Recipe | The ordered checklist to generate a new app |\n| Genericity Matrix | What is reusable vs what you must write |\n\n## For AI agents\n\nThis content is served as MCP resources under `docs://index`, `docs://nav`,\nand `docs://modules/{module}`. To build a new app:\n\n1. Read `build_recipe` first.\n2. Read `genericity_matrix` to know what you must author.\n3. Query the **library registry** (`find_library`) before writing any\n   infrastructure yourself.\n4. Copy the `templates/` skeleton and fill the two app-specific axes.\n",
