Production-focused view of the pipeline: content firewall, idempotency and lock behavior,
quality gates, atomic writes, manifests, status telemetry, and local outcome feedback.
Content firewall treats job description text as untrusted input and strips injection patterns.
Idempotent track flow plus lock rails prevents duplicate write storms under concurrency.
Quality gate is deterministic and fail-closed before final artifact export.
Outcome feedback enables local reinforcement without cloud data dependency.
