1
Source evidence
Original quotes, documents, records, and structured inputs retained with the finding.
Audit readiness
See how the analysis was put together.
This sample shows the information used, the work performed, the checks recorded and the cost information available for review. An auditor can use these records alongside their own tools and other supporting evidence.
For an engagement, agree which sources, checks, approvals and records are included. Reviewing those records or repeating selected checks does not regenerate the original AI answer.
Sample Audit Readiness Report
Original Acme example / plain-language reader edition
19 pages, including a new reader’s guide. Original sample figures, cost tables and detailed records are retained. The sample is fictional; actual evidence depends on the engagement.
Evidence architecture
Audit readiness is a data-design problem.
A polished report is not enough. Reviewers need the available source support, calculation context and qualifications, with a clear account of which checks a compatible receiver can repeat.
2
Calculation record
Formulas and deterministic transformations separated from model interpretation.
3
Validation record
Reconciliations, exceptions, constraints, and confidence classifications recorded.
4
Authority record
Required approvals, overrides, policy checks, and accountable owners retained.
5
Change history
Material edits and remediation actions remain visible instead of replacing the prior state.
6
Review export
A structured evidence package can be produced for management, finance, compliance, or external review.

Finance & accounting
Support the assessment. Do not pre-decide it.
For accounting questions, MCOS can preserve cost evidence, development records, management authorization, calculations, and control evidence that finance teams and auditors can evaluate under the organization’s applicable policy and guidance.
Governance & compliance
Show the control, not just the policy document.
Sentinel records policy checks, required approvals, exceptions, and blocked actions so governance can be examined as executed behavior rather than inferred from documentation alone.
