Problem
The user problem
Finance reviewers can see a workbook's totals without knowing whether formulas repeat consistently, depend on hidden or external sheets, contain stored errors, or include manual overrides. The Analyzer exposes those signals before anyone relies on the file.
Context
Project context
This is an independently owned working product. The public site contains the stronger browser-local Analyzer, a synthetic test, and a versioned release receipt. The full v1.34 Agent remains a separate local Python and SQLite runtime.
Workflow
Steps from question to review
- Read .xlsx, .xls, .csv, and .tsv inputs locally without upload; use a cancellable same-origin Worker when available and a labeled local fallback otherwise
- Profile Sheet structure, field roles, formulas, hidden content, and calculation settings
- Group relative formula families; surface minority patterns and stored Excel errors
- Map cross-Sheet and external dependencies while marking dynamic or unsupported references as unresolved
- Filter the review queue and export matching Markdown, HTML, and JSON evidence
- Keep governed Build, Standardize, Query, Enterprise, and Git Skills in the separate local runtime
Controls
Controls I chose
- Source facts remain unchanged and never leave the device on the browser path.
- Formula differences remain review candidates rather than proven errors.
- Dynamic, structured, 3-D, whole-column, and whole-row forms remain explicit gaps; external references remain bounded dependency evidence rather than invented full lineage.
- No AI output becomes an approved accounting definition or action without human authority.
- The public release remains static and credential-free; the five Agent Skills stay local.
Evidence
What has been verified
- The browser-local Analyzer groups relative formula families, flags minority patterns, preserves Excel errors, maps cross-Sheet and external dependency evidence, discloses dynamic-reference gaps, and exports a filterable Workbook Review Map plus Markdown, HTML, and JSON reports.
- The stable v1.34.0 local authority includes five Skills and 76 shared contracts; all 39 product-core checks and the 23-command synthetic smoke passed.
