Description

Session Goal

Reconstruct the architecture of the identity-resolution repository by separating the desired contract, the real artifacts, and the probable data lineage. The session aimed to determine whether the repo is a reusable, hardened package or mainly a wrapper around legacy notebook-era outputs.

Key Activities

  • Prioritized inspection of pipeline contracts, source code, tests, notebook inventories, schema samples, and generated manifests before large CSVs.
  • Proposed a repository triage and observation plan to screen artifacts in a way that reveals architecture rather than just file presence.
  • Distinguished between a modern scaffold (paths, IO, schema, CLI) and legacy working artifacts, using that contrast to infer maturity and reuse potential.
  • Reverse-engineered the data layers from CSV outputs, identifying staging, processed identity tables, canonical/export snapshots, and review surfaces.
  • Noted the risk of dual ID universes and the need to verify lineage with minimal tests and canonical file checks.
  • Recommended CLI help commands and profiling steps to validate implementation completeness and support a data catalog.

Achievements

  • Clarified the main analytical frame: move from a code map to a data map.
  • Established a practical separation between:
    • the contract that should exist,
    • the artifacts that actually exist,
    • and the lineage that is most likely true.
  • Identified April 2026 CSV-based outputs as the operational truth, while treating the newer scaffold as a contractual layer still needing alignment.
  • Produced a conceptual architecture for legacy and modern identity-resolution artifacts that can guide documentation and re-entry into the repo.

Pending Tasks

  • Verify whether the modular package is production-ready or only a thin wrapper around earlier outputs.
  • Run the minimal tests and canonical file checks needed to confirm lineage and implementation completeness.
  • Document the repository’s data catalog, including staging, processed, canonical, and review layers.
  • Align the scaffolded paths/IO/schema/CLI with the April 2026 working artifacts.
