Owner-only durable feedback ingest. Auth posture matches `GET /app/{id}/diag` (`requireAppAccess`): app token, user token, render token, or claim cookie. Body is capped at 96 KiB wire / 16 KiB text / 64 KiB serialized `structuredData`. The MCP `submit_feedback` tool forces `source="agent"` server-side; direct REST callers may set `source` to `user` or `auto-crash`.
