# BIPA Pre-IdentityD Biometric Attestation

**Date:** 2026-05-03
**Spec:** docs/PHASE_1_6_BIPA_GATES.md §2
**Generator:** scripts/staffing/attest_pre_identityd_biometric_state.sh

## Purpose

This is a one-time defense artifact establishing that, as of
2026-05-03, no biometric identifiers or biometric information
from real candidates have been collected, processed, or stored
by the Lakehouse system. It is intended to be signed by J
(operator of record) and outside counsel, then anchored to a
tamper-evident store (filesystem with backups + version control).

## Evidence

## Check 1 — workers_500k.parquet schema (no biometric columns)

**Source:** `data/datasets/workers_500k.parquet`

**Schema columns** (18 total):

```
worker_id	int64	nullable=True
name	string	nullable=True
role	string	nullable=True
email	string	nullable=True
phone	string	nullable=True
city	string	nullable=True
state	string	nullable=True
zip	int64	nullable=True
skills	string	nullable=True
certifications	string	nullable=True
archetype	string	nullable=True
reliability	double	nullable=True
responsiveness	double	nullable=True
engagement	double	nullable=True
compliance	double	nullable=True
availability	double	nullable=True
communications	string	nullable=True
resume_text	string	nullable=True
```

**Schema SHA-256:** `973b9abe56420de8f88122278b633e813f90a64cf0ddaac6a9811dc0940be676`

  - PASS: no biometric / photo / face / image column present

## Check 2 — KB + pathway memory contain no biometric payloads

**Sources scanned:**
- `data/_kb/*.jsonl` (knowledge base)
- `data/_pathway_memory/state.json` (pathway memory state)

**Files scanned:** 33
**Forbidden-pattern hits:** 0

  - PASS: no biometric payload patterns found in scanned files

## Check 3 — Headshots manifest is synthetic-only

**Source:** `data/headshots/manifest.jsonl`

**Total rows:** 1000
**Rows tagged real/candidate_upload/photo_upload:** 0

  - PASS: all 1000 rows are synthetic (no real-candidate uploads)

## Summary

**3 / 3** evidence checks pass.
