Errors and next actions

A consistent error envelope guides recovery without disclosing sensitive data.

Reliability, concurrency and recovery

Retry design follows the side effect rather than repeating every request blindly.

Contract boundary

Design payment requests from acceptance; no payable QR is generated.

Exceptions and reconciliation

After timeout, query state rather than create another transaction/command with an unknown prior outcome. Retain correlation/version/evidence without records or credentials in logs.

Integrity, provenance and evidence

Each evidence type answers a different question; hashes, timestamps and approvals are not interchangeable.
