Provenance & Tracing Architecture¶
Cross-cutting infrastructure establishing unified patterns for tracking data lineage, request tracing, and operation provenance across all layers of TNH Scholar.
Overview¶
Provenance infrastructure provides consistent mechanisms for answering "where did this come from?" across different operational scopes—from CLI invocations to AI generations to document transformations.
Architecture Decision Records¶
- ADR-PV01: Provenance & Tracing Infrastructure Strategy - Establishes foundational patterns for cross-cutting provenance tracking across all layers
Key Concepts¶
- Request Tracing: Track individual operations through the system (CLI commands, API requests)
- Service Provenance: Record how AI/processing results were generated (model, parameters, fingerprints)
- Data Lineage: Chain of transformations from source to derivative artifacts
- Reproducibility: Sufficient metadata to recreate results
