The situation

The agency reviews roughly 700 independent public audits per year. Every review was 100% manual, consuming 4 to 24 hours per audit due to non-standardized layouts, siloed data systems, and manual balance sheet math checks. Previous commercial AI tools failed with high false positive rates in budget schedules.

What we built

In an 8-week compressed build under a strict fiscal-year deadline, we built 'Reviewer Zero'. We established a 3-layer architecture: Layer A (deterministic bytes classification & financial facts ledger), Layer B (reasoning agent for compliance guidelines), and Layer C (faithfulness gates & 7-year audit retention locks).

100% deterministic financial ledger math checks (zero model hallucination)
Dual-citation verification: resolves audit text and governing standard
Content-based word geometry highlight resolution instead of page numbers
Product contract: AI never authors letter comments; humans write feedback
7-year immutable compliance retention lock on all generated reports
Live API integration with third-party audit submission portal

Both contracted deliverables were formally accepted, leading to a follow-on engagement. Reduced review prep time from hours to minutes, enforced deterministic math (zero model-generated numbers), and delivered 153 infrastructure-as-code resources in the client's government cloud tenancy.

Sitting in and listening to the auditors directly gave us the client's actual north star, not our interpretation of it.
