Spreadsheet Trust Auditor
Spreadsheet Trust Auditor is the demo wedge for Verifiable Work Product: it helps humans and agents decide whether a spreadsheet can be trusted, mapped into ACE, or escalated for review without pretending to recalculate every arbitrary Excel workbook.

Who it is for
Advisors, operators, analysts, auditors, and agents receiving spreadsheets from customers or internal teams.
Problem it solves
Spreadsheets often look authoritative while hiding stale values, broken references, manual overrides, and unclear structure. The auditor gives a fast trust report and an ACE-ready intake path before anyone relies on the file.
Activation model
Assisted setup for tenant upload policy, retention, ACE intake mapping, and review receipt workflow.
Proof and source paths
- CleverQ upload form accepts Excel and CSV workbooks for ACE ingest
- ACE ingest returns mapping strategy, table summaries, row counts, warnings, and scenario ids
- Formula-risk is surfaced honestly instead of overclaiming full Excel recalculation

Capabilities
spreadsheet trust audit
workflowUpload a spreadsheet and receive a trust report with mapping, warnings, and ACE-ready intake evidence.
Agent use
Use stackfast.spreadsheet.audit for structural trust audit of uploaded .xlsx workbooks. Primary path returns CleverQ ACE-backed findings (ace_primitive_exposure). If ACE is unavailable, the tool returns structural_xlsx_audit_fallback with a notice; fallback counts may differ from ACE ingest. The tool does NOT recalculate arbitrary Excel formulas.
Connector proof
Catalog is not the same as customer-ready.
This product only becomes market-ready after a real host mounts the entitled tools, a safe call succeeds, metering records the event, and a customer-safe receipt exists. Until then, the page shows the strongest proven status without rounding up.

Runtime registry and product manifest are present.
Entitlement
Execution requires OAuth or storefront entitlement scope.
Callable
Callable tool proof is incomplete.
Metering
Metering waits on callable execution.

Install gate
Install-ready graduation requires a dedicated spreadsheet audit MCP tool and smoke-tested agent upload flow; the human CleverQ upload path is available for assisted use.
