ADR-006: Local Jobs with Persistent History

Status: Accepted
Date: 2026-08-23 (retrospective)

Context

In-memory queue states persist in background_jobs. Rationale inferred from current architecture.

Decision

Backend executes jobs with priority, deduct, retry and local recovery.

Alternatives

Synchronous execution; external broker.

Consequences

No additional infrastructure and recovery; concurrency/coordination remains limited to one instance.
