Description

Session Goal

Diagnose the lineage of the FCEN identity-resolution system and determine whether the current Python package is the authoritative production pipeline or only a migration scaffold.

Key Activities

• Reviewed multiple reflection notes comparing src/fcen_intel/identity against the richer April 2026 notebook-based workflow.
• Traced architectural signals across notebooks, generated artifacts, and package structure to infer the true operational chain.
• Compared artifact freshness and grain consistency, especially around person_vote_info.[[csv]], person_index.[[csv]], and person_siu_links.[[csv]].
• Formulated a reverse-engineering / reentry plan focused on notebook lineage, high-value extraction commands, and documentation-first stabilization before refactoring.

Achievements

• Established that the current Python package is a partial hardening scaffold rather than the source of truth.
• Identified the April 2026 notebook pipeline as the authoritative production chain.
• Clarified that person_vote_info.[[csv]] appears stale relative to notebook-generated outputs.
• Isolated a narrow duplicate-key / person_id grain issue affecting person_index.[[csv]] and person_siu_links.[[csv]].
• Proposed deterministic rebuild and audit checks for freshness, uniqueness, and referential integrity.

Pending Tasks

• Trace notebook lineage to locate the exact blocks that generate the authoritative artifacts.
• Verify freshness and integrity of all exported CSVs.
• Rebuild person_vote_info.[[csv]] deterministically from the notebook pipeline.
• Add audit scripts or checks to prevent duplicate writes, stale exports, and absolute-path brittleness.
• Capture a concise runbook for reentry into the pipeline and future refactors.
