Production integration baseline

Treat these guides as one control set. Authentication protects request integrity; idempotency protects mutations; pagination and synchronization protect completeness; error handling controls retries; reconciliation detects financial mismatch; security defines the surrounding trust boundary.

Before production, demonstrate restart recovery after sending a create request but before saving its response, after saving a batch but before its cursor, and while a transaction is non-final. Recovery must not duplicate financial effects or lose records.
