gRPC

Purpose

Guide inbound gRPC adapter work while keeping transport concerns outside the domain and application core.

Practices

• Keep Protobuf DTO mapping inside the gRPC adapter.
• Validate transport-level fields before creating application requests.
• Preserve correlation, session and evidence identifiers exactly.
• Apply .agents/skills/resilience-engineering/SKILL.md for gRPC deadlines, cancellation, bounded retries, idempotency, retry provenance and degraded transport behavior.
• Do not treat transport metadata as domain evidence unless the contract says so.
• Keep service methods thin and delegate use cases to application ports.
