*
* Validated through the production `ValidationPipe({ whitelist, forbidNonWhitelisted, transform })`:
* a UUID conversation id; `content` trimmed then bounded to 1..10_000 characters (whitespace-only
* collapses to empty and fails `@IsNotEmpty`); a nested `selection` object recursed with an
* explicit `@Type` (a bare `@ValidateNested` is masked green by class-validator's empty-metadata
* `unknownValue`); and a UUID-v4 idempotency key. No `provider`/`modelId`/`attachments` or other
* authority field is declared, so `forbidNonWhitelisted` rejects every unknown top-level key.
