Data Contract Enforcer
Enterprise Data Reliability Engineer
Schema integrity and lineage attribution system that turns inter-system dependencies into formal contracts, detects schema/type/statistical drift, and reports downstream blast radius.
"Made AI pipeline contracts executable: validate, attribute, and explain exactly which consumers break when data drifts."
Problem
Multi-system AI pipelines silently break when upstream schemas drift, confidence scales change, enums mutate, or event payloads stop matching downstream expectations.
Solution
Implemented contract generation, validation, violation attribution, schema evolution analysis, AI-specific drift checks, and stakeholder reports backed by registry-first blast-radius analysis.
Deep Dive
What It Enforces
Data Contract Enforcer manages contracts across a five-system AI pipeline: Intent-Code Correlator, Digital Courtroom, Document Refinery, Brownfield Cartographer, and Axiom Ledger.
Engineering Highlights
- •Contract generation: profiles JSONL into Bitol YAML, dbt schema files, and timestamped snapshots.
- •Validation runner: catches type, range, enum, UUID, and statistical drift in audit, warn, or enforce mode.
- •Violation attribution: combines dependency registry, lineage BFS, and git blame to produce actionable blast-radius reports.
