+feat(spec,client): declare the publish door's response — `PublishMetaItemResponseSchema` (#7294)
+
+`POST /api/v1/meta/:type/:name/publish` has been served since long before this
+change, and had no contract behind it: the string `PublishMetaItem` appeared
+nowhere under `packages/spec/src/`, and the endpoint was absent from
+`plugin-rest-api.zod.ts`'s metadata table. So `version` on the publish response
+sat in exactly the state `version` on the *save* response sat in before #5745 —
+the ADR-0008 optimistic-concurrency token, the value a caller echoes back as
+`If-Match` to get a 409 instead of a lost update, riding a public wire surface
+with nothing declaring it. `PublishMetaItemResponse` could not be named at the
+type level either, which is why `client.metadata.publishItem()` resolved to
+`any`.
+
+This carries the #5745 "declared = returned" discipline one door over, with the
+same three artifacts the save door has:
+
+- **`PublishMetaItemResponseSchema`** declares the FULL measured body —
+  `success` / `version` / `seq` required, `message` and the three conditional
+  side-effect receipts (`seedApplied` / `materializeApplied` /
+  `projectionApplied`) optional. Optionality is measured, not assumed: the sole
+  producer's single response literal always sets the first three, and attaches
+  each receipt only when the matching side effect ran, so an absent receipt
+  means "that side effect did not run", never "it failed".
+- **The endpoint declaration**, so the catalog names the route it serves and
+  points at the schema. No `requestSchema`: the body's only read key is
+  `message`, taken only when already a string, so the route cannot 400 a
+  malformed body and declaring one would advertise a gate that does not run.
+- **A producer-side conformance gate**
+  (`publish-meta-response-conformance.test.ts`), driving a real
+  `publishMetaItem` against a real ObjectQL engine through the schema across
+  the plain shape and every receipt path. A field added to the response, or
+  dropped from the schema, now turns that red instead of silently vanishing at
+  parse.
+
+`client.metadata.publishItem()` is typed `Promise<PublishMetaItemResponse>` and
+the type is re-exported, matching `saveItem` / `SaveMetaItemResponse`.
+
+Also fixes a declared-≠-returned gap one layer down: `publishMetaItem`'s own
+`Promise<...>` annotation omitted `projectionApplied` while the implementation
+assigned it, so the method's type denied a key its callers were receiving.
+
+No behavior change — nothing about the response body moved. This declares what
+was already on the wire.

+
+### Properties
+
+| Property | Type | Required | Description |
+| :--- | :--- | :--- | :--- |
+| **success** | `boolean` | ✅ | Always true on a 2xx — the draft was promoted. It does NOT cover the best-effort side effects below, each of which reports its own `success`. |
+| **version** | `string` | ✅ | Content hash of the just-promoted body, and the token the ADR-0008 optimistic-concurrency chain runs on: send it back as the `If-Match` request header on the next write to that item and a concurrent edit is reported as 409 `metadata_conflict` instead of silently overwritten. Opaque to callers — echo it verbatim, never parse it. Currently emitted as `sha256:<64 hex chars>`, but the format is not part of this contract. |
+| **seq** | `integer` | ✅ | Monotonic sequence number of the `op='publish'` metadata event this promotion appended to the item history (sys_metadata_history.event_seq). Orders writes; unlike `version` it is not an OCC token. |
+| **seedApplied** | `{ success: boolean; inserted: integer; updated: integer; error?: string; … }` | optional | Outcome of materializing a published `seed` body into data rows. Present ONLY when the published type is `seed` — publishing a seed is what makes its rows live, so the load rides along with the metadata promotion. Best-effort: a seed-load problem is surfaced here, never thrown, so a caller must check `seedApplied.success` instead of assuming the 200 covered the data. Absent on the batch path, which suppresses the per-item apply and loads every seed body in one later pass. |
+| **materializeApplied** | `{ success: boolean; inserted: integer; updated: integer; error?: string }` | optional | Outcome of the ADR-0086 P2 publish-time materializer — the step that projects the published body into its data-plane row (e.g. `permission` → `sys_permission_set`, under the owning package). Present ONLY when a materializer is registered for this metadata type, which is why it is optional: its absence means "no materializer ran", never "it failed". Best-effort, same contract as `seedApplied`. |
+| **projectionApplied** | `{ success: boolean; error?: string }` | optional | Outcome of the awaited ADR-0094 mutation projector — the post-persist step that materializes this metadata into its derived data-plane read model. The same receipt `{@link SaveMetaItemResponseSchema}` carries, because the projector runs on BOTH write doors: a direct active save and this draft→active promotion. Present ONLY when a projector is registered for this metadata type. Best-effort — a projector failure is reported here and logged, never thrown. |
+| **message** | `string` | optional | Human-readable receipt, e.g. `Published draft — type=view, name=cases [seq=3]`. The producer sets it on every publish today; it stays optional to match the producer's own signature and its `SaveMetaItemResponse` twin, and because an absent human-readable string strips no data — the failure mode #5745 exists to prevent. |
