"""Production pipeline: sourcing -> extraction -> canonical ER -> QA -> quality.
Identity decisions are owned by src/er/entity-resolution-service.ts. The
Python worker only applies canonical `match` decisions returned by its
internal bridge. If tenant context or the canonical bridge is unavailable,
records remain unmerged: false identity merges are never used as fallback.
