  "body": "# @leumas/middleware\n\nThe adapter/connector engine (P1 slice). Provides the **schema-less dynamic CRUD** path that\ncomplements the typed core in [`@leumas/db`](../../packages/db) — both over the **same** `leumas.db`.\n\n- `BaseAdapter` — the one storage-adapter contract (harvested from legacy `leumas-middleware`).\n- `LibsqlAdapter` — stores each app-defined collection as `dyn_<name>` (id, data JSON, owner, public, timestamps), created on first write.\n- `createConnector(config)` — the loader (defaults to a single libSQL adapter).\n- `createDynamicCrudRouter({ adapter, requireAuth })` — Express CRUD at `/db/:collection`, ownership-gated. `requireAuth` is injected so this engine stays decoupled from `@leumas/auth`.\n\n```js\nimport { createConnector, createDynamicCrudRouter } from '@leumas/middleware';\nimport { requireAuth } from '@leumas/auth';\nconst connector = createConnector();\napp.use('/db', createDynamicCrudRouter({ adapter: connector.get(), requireAuth }));\n```\n\nThe full adapter loader/introspection engine + the `a.*`/`b.*` adapter packs land in **P3**; P1 ships\nonly the DB-connector slice needed for dynamic app data.\n",
