What narrows is the accept set of four of this package's own routes for one input: a body declared as JSON that does not parse, which used to be read as no body. The remedy is in the requests a client sends, never a rewrite of a package source or a stored row. The other categories are closed on facts: the package publishes (not unpublished); no ADR-0087 id is named or touched (not registered or already-registered); and nothing exported is removed or narrowed (not runtime-interface-only, type-surface-only or runtime-export-retired). -->

+
+What changes for an integrator. A body sent as `application/json` (matched case-insensitively) that is not blank and does not parse: FROM the route's answer for an empty body, TO `400` with `{ "success": false, "error": { "code": "INVALID_REQUEST", "message": "The request body could not be parsed as JSON (it was sent as application/json). It was refused rather than read as an empty body: send a well-formed JSON document, or no body at all." } }`. Install-local refuses it after its sign-in and capability checks and before anything is fetched, registered or written.
+
+**Remedy, in one line.** Send a JSON body as well-formed JSON with `Content-Type: application/json`, or send no body.
+
+**Unchanged.** An empty or whitespace-only JSON body is still no body, and every route answers it as before (for `/bind/poll`, `400 "device_code is required"`). A body that parses, and a body that does not declare JSON, are read as before.

+
+The `${prefix}/*` catch-all handed `dispatch()` `{}` for a body that did not parse, and the data domain read that as an empty query or an empty update: a truncated `POST /data/OBJECT/query` answered every row the caller could read, and a truncated `PATCH` answered `200` for an update that changed nothing.
+
+What changes for an integrator, on a host that serves `createHonoApp`:
+
+- A `POST`, `PUT` or `PATCH` body sent as `application/json` (matched case-insensitively) that is not blank and does not parse, to a domain that reads the parsed body (the data, metadata and every other domain that takes `body`): FROM that domain's answer for `{}`, TO `400` with `{ "success": false, "error": { "code": "INVALID_REQUEST", "message": "The request body could not be parsed as JSON (it was sent as application/json). It was refused rather than read as an empty body: send a well-formed JSON document, or no body at all." } }`. The domain acts on nothing past its read of the body, and the dispatcher's own gates still answer first. This is the same status and body `@objectstack/plugin-hono-server` answers for the same request.
+- The same applies to the `/auth/*` legacy fallback that runs when no auth service is registered, for every method it hands a body (all but `GET` and `HEAD`).
+
+**Remedy, in one line.** Send a JSON body as well-formed JSON with `Content-Type: application/json`, or send no body.
+
+**Unchanged.**
+
+- An empty or whitespace-only JSON body is dispatched as `{}` (an empty query), as before.
+- A body that does not declare JSON is read as before: parsed when it is JSON, `{}` when it is not.
+- The request handed on beside the body still arrives unread, in every case. A domain that forwards it and reads its own bytes answers exactly as before, a malformed JSON body included: `/webhooks/redeliver` and the inbound automation hooks give their own refusal after their own sign-in or signature check, and the `/approvals/act` form `POST` reads its form.
+- The catch-all dispatches `GET`, `HEAD` and `DELETE` with no body, and the `/auth/*` fallback hands `GET` and `HEAD` `{}`, as before.

+fix(plugin-hono-server)!: a request body the adapter cannot parse is refused `400 INVALID_REQUEST` when a route handler reads it, never handed to the handler as `{}`
+
+Clause-②: no (narrowing)
+
+<!-- adr-0087: not-required (no-migration-prescription) No metadata moves: no spec key, authorable spelling, object definition or stored shape is added, removed, renamed or re-shaped, no stored row is rewritten or deleted, and no exported declaration is added, removed or narrowed, so there is nothing for `objectstack migrate meta` to rewrite. What narrows is the accept set of the HTTP transport for request bodies it cannot parse: a malformed declared-JSON body, a malformed form, or a body in a media type it does not read, each of which used to reach the handler as `{}`.

+
+**BREAKING** (an accept-set narrowing), shipped as `minor` under the launch-window convention for breaking changes.
+
+The adapter used to build a route's `req.body` as `{}` and overwrite it only when a parse succeeded, so a body it could not parse reached the handler as an empty object. Measured on a fresh `objectstack dev` showcase boot: `POST /api/v1/data/showcase_account/query` with its closing brace missing, with `{ not json`, or with a valid body sent as `text/plain` answered `200` with all 14 rows where the filter matched 2; a truncated `PATCH` answered `200`, changed no field and moved `updated_at`; and a truncated create answered `400 VALIDATION_FAILED` "Account Name is required", for a body that carried a name.
+
+What changes for an integrator. Each refusal is `400` with `{ "success": false, "error": { "code": "INVALID_REQUEST", "message": "…" } }`, raised when the handler reads `req.body`, so the handler acts on nothing past that read and nothing is written. The message names the failure and never echoes the body.
+
+- A body sent as `application/json` (matched case-insensitively) that is not blank and does not parse: FROM the handler reading `{}`, TO the refusal "The request body could not be parsed as JSON (it was sent as application/json). It was refused rather than read as an empty body: send a well-formed JSON document, or no body at all."
+- A body in a media type the adapter does not parse (`text/plain`, `application/octet-stream`, any other type, or no `Content-Type` at all) sent to a route that reads `req.body`: FROM `{}`, TO the refusal "The request body was sent as text/plain, which this server does not read into a request body. It was refused rather than read as an empty body: send it as application/json."
+- A `multipart/form-data` or `application/x-www-form-urlencoded` body that does not parse: FROM `{}`, TO the refusal naming form data.
+
+**Remedy, in one line.** Send a JSON body as well-formed JSON with `Content-Type: application/json`, or send no body.
+
+**Unchanged.**
+
+- An empty or whitespace-only JSON body is still `{}`, which the REST data doors read as an empty query; a request with no body is still `{}`, whatever it declares.
+- Well-formed JSON and well-formed forms reach the handler parsed, as before.
+- A route that reads `req.rawBody()` and never `req.body` receives any media type byte for byte, as before: the storage raw upload stores a JSON-with-comments file sent as `application/json` (the type its presign tells the client to send for a `.json` file) and a text file sent as `text/plain`.
+- A route, or the unmatched-request fallback, that never reads `req.body` answers as before.
+- A body is judged present by its framing headers (`Content-Length` other than `0`, or `Transfer-Encoding`), as RFC 9112 defines it; nothing is read to find out.

+ * write that changed nothing).
+ *
+ * The dispatcher is a fixture (this package's config aliases
+ * `@objectstack/runtime` to a stub), standing in for the two kinds of domain:
+ * a READER (`/data/*`, `/meta/*`), which reads `body` inside a `try` whose
+ * catch answers its own `500`, so a pin that passes proves the adapter's
+ * answer won; and a FORWARDER (`/webhooks/redeliver`), which reads its own
+ * bytes from the forwarded request and never touches `body`, as the real
+ * webhooks, inbound-hook and `/approvals/act` domains do. The real dispatcher
+ * and the real domains are driven in
