# OBPI-0.7.0-03-ledger-first-obpi-audit-consumption: Ledger First Obpi Audit Consumption

## ADR Item

- **Source ADR:** `docs/design/adr/pre-release/ADR-0.7.0-obpi-first-operations/ADR-0.7.0-obpi-first-operations.md`
- **Checklist Item:** #3 — "Move audit readiness to ledger-first OBPI consumption."

**Status:** Completed

## Objective

Make OBPI completion/audit checks consume ledger proof as primary evidence instead of relying only on brief text inspection.

### Implementation Summary

- Files modified: `src/gzkit/ledger.py` (added `ledger_completed` to artifact graph), `src/gzkit/commands/status.py` (updated `_inspect_obpi_brief` to prioritize ledger), `src/gzkit/cli.py` (passed graph to audit checks).
- Date completed: 2026-03-04

### Value Narrative

Before this OBPI, OBPI completion and audit checks relied on parsing brief markdown files as the source of truth. After this OBPI, audit checks consume ledger proof as primary evidence, making completion state deterministic and resistant to brief text drift.

### Key Proof

```bash
# Audit check now explicitly requires ledger proof:
uv run gz adr audit-check ADR-0.7.0-obpi-first-operations
# Output includes: "ledger proof of completion is missing" for drafts.
```

## Human Attestation

- Attestor: human:jeff
- Attestation: "Confirmed status surfaces now prioritize ledger records over file metadata."
