+# Standards Reference
+
+The reference half of the Standards description: the enforceable rules,
+patterns, and the internal library catalog that agents consult while coding.
+
+- **Layering Rules** — the strict request → domain → repository layering and
+  the rules that enforce it.
+- **Composition Root** — a single composition point wiring the whole app.
+- **Spec-First Routing** — the OpenAPI contract as the routing source of truth.
+- **CRUD Template** — the standardized generic resource endpoint scaffold.
+- **Pipeline Scaffold** — the deterministic pipeline skeleton for multi-stage
+  jobs.
+- **Worker & Progress** — queued work, progress reporting, and visibility.
+- **Human-in-the-Loop** — guardrails and approvals inside automations.
+- **Infra Adapters** — how infrastructure connects without leaking into domain.
+- **Genericity Matrix** — what is generic vs app-specific.
+- **Library Registry** — the catalog of internal libraries behind all of it.
+
+Read the **Wiki** for the philosophy and rationale; these pages are the
+reference that mirrors the `standards` MCP bundle.
