S14: Map exact duplicate documents without deleting evidence
Expected synthetic fixture result
Proposed / not tested

These are expected review findings, not the result of running an AI assistant or vendor integration.

1. F1/F2: exact same hash and 100-byte size, but preserve both file IDs, distinct batches/custodians/families and paths in a candidate duplicate group.

2. F5: hash matches F1/F2 but size 101 conflicts with 100; flag inconsistent manifest evidence, exclude F5 from the exact-size group and require verification of the whole hash cluster.

3. F3: different hash/size remains ungrouped. Do not infer near/page-level duplication.

4. F4: missing hash remains unresolved, not unique-by-proof.

5. No file is deleted, withheld, or selected for production based on this map.

Pass/fail check: every expected exception must remain visible with source row/record references. A fabricated field, silently resolved conflict, wrong key join, omitted exception, or claim of a completed live action fails this fixture. Wording may vary; findings and boundaries may not.
