Lab / Static prototype
Statement analysis review
A reviewer-facing statement workbench: inspect synthetic financial inputs, verify calculated ratios, and read a short set of arithmetic observations with their formulas.
Static browser app for Cloudflare Pages. All scenarios are invented. No uploads, external requests, model calls, or stored user data. The observations describe arithmetic, not causes or recommendations.

Arithmetic observations
- Revenue change is unavailable because no comparable prior period was supplied.
- Gross-margin change is unavailable because no comparable prior period was supplied.
- Current ratio is not calculated because current liabilities are zero.
- Current-ratio change is unavailable without two comparable, non-zero-liability periods.
- These observations describe arithmetic only; they do not identify causes or recommend action.

Deployment boundary
This demo is a deterministic baseline, not the private LLM prototype and not a production finance system. It runs from static assets and needs no server-side runtime or secret. A real deployment would first need permission-aware data access, approved metric definitions, durable review records, failure controls, and domain-reviewed evaluation.
