ADR-005: Async Worker Orchestration for Verification and Anchoring

Status

Accepted

Context

Verification, scoring, and anchoring are latency-variable workflows and should not block user-facing submission calls.

Decision

Use asynchronous worker orchestration with idempotent event handlers for:

• verification pipeline
• points credit/debit posting
• blockchain anchor batching

Synchronous API path is limited to validation + persistence + enqueue.

Consequences

• Stable client response times and resilient retries.
• Requires queue operations, dedupe keys, and stronger observability/runbooks.
