 The handler ships a standard route pack — `GET / POST /`, `GET PUT PATCH DELETE /:key`, `GET DELETE /-by-names`, `PUT /-load`, `PUT /-clone`, `PUT /-move`, `PUT /-clone-by-names`, `PUT /-move-by-names`, `PUT /:key/-clone`, `PUT /:key/-move` — with envelope keys, status codes, and prefixes all configurable via `options.policy`.
 
+## Framework adapters
+
+The bundled `dynamodb-toolkit/handler` is a pure `node:http` handler. Framework-specific bindings live in separate packages so the core stays zero-dep — each adapter is a thin wrapper that translates its framework's request/response shape into the toolkit's `rest-core` parsers + standard route pack. The wire contract (routes, query parameters, envelope keys, error mapping) is identical across all four.

+### 7.4 Framework adapters (separate packages)
+
+The bundled handler in this package is `node:http`-only. Framework-specific bindings ship as separate unscoped npm packages so the core keeps zero runtime dependencies. Each adapter is a thin wrapper (~150–300 LoC) that translates its framework's request/response shape into calls through the same `rest-core` parsers/builders + `matchRoute` used by the bundled handler. The wire contract (routes from §7.1, query parameters from §7.2, error mapping from §7.3, envelope keys from `policy`) is identical across all four.

+The bundled `dynamodb-toolkit/handler` is `node:http`-only. Framework-specific bindings ship as separate packages (zero runtime deps in the core; frameworks are peer deps of each adapter). All four adapters share the same wire contract (routes, query parameters, envelope, error mapping) as the bundled handler.
