+fix(runtime): `publish-drafts` no longer discloses driver or subscriber text on `unhideError` / `rebindError` (#8516)
+
+`POST /api/v1/packages/:id/publish-drafts` answered, on a **200**:
+
+```json
+{ "success": true, "data": {
+  "unhideError": "SQLITE_ERROR: no such table: sys_metadata",
+  "rebindError": "TypeError: Cannot read properties of undefined (reading 'triggers') at AutomationPlugin.rebind (/srv/objectstack/packages/services/service-automation/dist/index.js:412:31)" } }
+```
+
+These are the two remaining producers on the response whose `seedApplied` field
+#8443 converted — the ADR-0045 visibility flip and the `metadata:reloaded`
+announce. Both ride a success body as **data**, so no HTTP boundary's 5xx
+message withhold can reach them; the disclosure had to be closed at the
+producer. Both were driven for real before being changed, and both reproduced.
+
+Both now follow the rule already in force next door: a caught sentence is
+quoted only when the error **declared** itself a client-facing refusal (4xx
+`status`, ADR-0112); anything else gets the stable sentence the field could
+already carry, and the original goes to the server log. The rule is imported
+from `@objectstack/metadata-protocol` (`clientFacingFailureText`), not restated
+locally.
+
+**Both halves of the rule, because the two sites started in different states.**
+The flip already logged its cause in full at `error` with an operator remedy, so
+only its payload changed. The announce had **no log line at all** — withholding
+alone would have converted an over-disclosure into a silent failure, so it gains
+one at `warn`, naming the cause, the concrete consequence (a newly published
+record-triggered flow does not bind its trigger until the process restarts) and
+the fix (re-run the idempotent publish, or restart). `warn` rather than `error`
+because nothing that claimed to persist failed to: the drafts are published and
+the flip is stored, and an unbound trigger is AGENTS.md's own worked example of
+a functional degradation — the level the sibling announce of this same event
+already uses.
+
+**Authoring feedback is preserved, not blanked.** The flip's authored refusals
+all declare 4xx (`ITEM_LOCKED`, `NOT_OVERRIDABLE`,
+`OBJECT_OVERLAY_PACKAGE_MISMATCH`, …), so a locked or non-overridable app still
+tells its publisher which app and why, verbatim — and the `unhiddenApps`
+half-flip report beside it is untouched. A subscriber that declares a 4xx
+refusal is quoted by the same positive list.
