Errors

idempotency_conflict

Returned as conflict_error with HTTP 409.

What happened

Reserved for a future general idempotency-replay contract. The current public API does not return this code.

How to fix it

Do not branch on this code today. Use a stable `external_id` for repeat deck imports and inspect the resource before retrying other writes after an unknown outcome.

The envelope
