## Outcome

Return an evidence-led comparison of selected related files, identifying likely
canonical candidates and ambiguity without treating similarity as authorization
to remove or replace content.

## Scope

Use only for a supplied document set and supplied canonical-source signals such
as owner, approved location, status, or effective date. It recommends review;
it does not decide records disposition.

## Host contract

| Item | Contract |
|---|---|
| Target host | Copilot in SharePoint, preview support status |
| Native surface | Selected library files, accessible metadata, and version indicators |
| Portable core | Evidence comparison, ambiguity detection, and canonical-candidate reporting |
| Host adapter | Reads only content and metadata available to the current user |
| Mutation | No moves, deletes, or archival changes; separate confirmed action required |
| Evidence | Analytical design only; no live library reconciliation has occurred |

## Procedure

1. Confirm the subject, selected file set, and authoritative canonical signals.
2. Compare accessible titles, locations, owner fields, approval or version
   markers, dates, and supplied content indicators.
3. Mark a result `LIKELY_CANONICAL`, `DUPLICATE_CANDIDATE`, `STALE_CANDIDATE`,
   or `NEEDS OWNER DECISION`; never call a candidate definitive without rules.
4. Return this table:

   | File | Signals observed | Candidate status | Conflicts | Confidence | Required owner decision |
   |---|---|---|---|---|---|

5. Verify that each status cites observed signals and that uncertainty remains
   visible when records disagree.
6. If cleanup is requested, provide an exact proposed action set and obtain
   explicit confirmation plus capability and permission checks first.

## Safe outcomes

- `NEEDS INPUT`: no selected set or authoritative canonical signals are supplied.
- `NOT SUPPORTED`: the host cannot inspect the needed metadata or content.
- `INSUFFICIENT PERMISSION`: the user cannot read the relevant files.

## Boundaries

- Do not infer approval from a filename, recency, or folder alone.
- Do not delete, archive, move, or overwrite files.
- Do not inspect external repositories or run custom code.

## Validation

Read `evals/evals.json` for analytical comparison, ambiguity, and cleanup-
boundary cases. No live host evidence exists for version 1.0.0.
