LCRE
Stage-edge contract verification that finds the first edge that broke in a multi-stage pipeline and emits a structured proof artifact.
What it is.
Multi-stage pipelines fail in cascades. The symptom you see at stage seven is rarely the cause — that lives at stage two. LCRE attaches lightweight contract verifiers at every stage edge and identifies the earliest edge whose contract was violated.
Output is a structured proof artifact: which edge, which contract, which row, which value. Downstream alerts that derive from the same root cause are suppressed in the same artifact, which collapses on-call noise on incidents that span stages.
Drops into Airflow, dbt, and custom orchestrators. No instrumentation of stage internals required — the contract is at the edge, not inside the operator.
What it does.
- 1 ms detection at the violating edge; 91 ms end-to-end on a 50,000-row real-data pipeline test.
- Symptom suppression — downstream alerts deriving from the same root cause are merged.
- Structured proof artifact per incident — edge, contract, row, value, suppressed-alert list.
- Airflow / dbt / custom orchestrator integrations; no stage-internal instrumentation needed.
- Read-only — does not gate, does not retry, does not mutate the pipeline.
Who it is for.
Data platform teams, ML feature-pipeline owners, and analytics engineering groups carrying multi-stage DAGs where root-cause analysis routinely consumes more incident time than remediation.
