Evidence and authority method

The wiki separates observed audit facts, workbook declarations, analytical interpretations, recorded decisions and unknowns, with evidence limitations stated beside affected findings.

# Method

This build uses two primary evidence artefacts:

- the deterministic audit of the connected Power BI Desktop model;
- the inspected workbook `TargetArchitecture_Partial.xlsx`.

Recorded consultant decision receipts provide authority for mapping confirmation and gap scope.

## Authority classes

| Authority | Use in this wiki |
|---|---|
| `observed` | Returned directly by the audit or exact workbook/evidence read |
| `declared` | Stated in the selected target workbook |
| `interpreted` | Analytical conclusion derived from evidence |
| `decided` | Confirmed by a recorded consultant decision |
| `unknown` | Not established inside the selected access boundary |

## Comparison approach

The target field list was compared with normalised current-model elements. Exact qualified-name candidates were reviewed and confirmed. Cases without a current candidate descended to bounded evidence packets and were then resolved by consultant decisions.

## Evidence discipline

- Existing names and data types support structural comparison, not full semantic equivalence.
- A workbook declaration is not an implementation record.
- A no-candidate result is bounded non-observation.
- A `confirm_gap` decision supports scope treatment but does not prove enterprise-wide absence.
- Unknowns remain explicit rather than being inferred away.

## Revalidation

A later snapshot, broader estate access, approved source design or revised target workbook should trigger revalidation of affected pages and mappings.
