# Charles River — Blank Evidence Template

Copy one template for each trace or investigation. Leave unsupported fields explicitly unresolved. This public method aid contains no independent-challenge solution.

## Question and scope

- Business question:
- Activity, lesson, or assigned case:
- Source filename and table:
- Assigned dataset baseline and checksum reference from Downloads:
- Lesson or case page:
- Tool used:
- Reporting cutoff and date basis (document, approval, posting, payment, or clearing):
- Included population and explicit exclusions:
- What one source row represents:
- What one output row represents:

## Evidence path

| Business event and operational date | Document or line key and row grain | Stored relationship or analytical support | Actual posting source type and ID, with posting date | Account effect or no-new-posting reason | Remaining obligation at cutoff |
|---|---|---|---|---|---|
| | | | | | |
| | | | | | |
| | | | | | |
| | | | | | |

## Method and checks

- Prediction before running:
- Saved query/workbook and named input/output steps:
- Filters and exact date bounds:
- Column data types, including dates and identifiers:
- Key uniqueness and null classes:
- Match counts and before/after row counts:
- Before/after amount checks and independent source check:
- Complete-voucher check or reason voucher scope is not applicable:
- Saved result filename, column headers, row count, and reopened-file check, including an explicit zero-row result when applicable:
- Any grain change and independent aggregation before comparison:
- Observed result and difference from prediction:
- Repair performed and recheck:
- Refresh result (for a workbook):

## Conclusion

- Finding stated using the defined measure:
- Supporting source identifiers and evidence:
- Recognition versus settlement explanation:
- Why does recognition or settlement occur now?
- Events excluded because they occur after cutoff:
- What this evidence does not establish:
- Alternative explanation or unresolved evidence gap:
- Recommended next action and evidence needed:

## Method review

Use the public method rubric. Record whether each criterion is demonstrated, needs repair, or is unresolved; do not replace missing evidence with an assumed answer.
