# Holographic Trace Stack Reassembly Harness v0.2.0 Validation Report

Validation timestamp: 2026-06-18T15:05:57.215661Z

## Verdict

**PASS**

v0.2.0 preserves the v0.1 bounded synthetic proof harness and adds the scoped forensic layer:

- per-contribution score panel
- motion-route segment ledger
- segment status labels: returned / missing / shuffled / reversed / conflicting
- segment-level coverage delta
- segment-level return contribution
- affected atom IDs
- receipt-facing reason lines

Boundary preserved: this remains a trace-structured holographic dataset proof only. It does not claim optical holography, 3D holography, cinematic rendering, or live mycelium/geometry rendering.

## Validation checks

## v0.2 forensic acceptance criteria

| Criterion | Result |
|---|---|
| v0.1 six-test harness preserved | PASS |
| per-contribution breakdown exposed | PASS |
| motion route segment ledger generated | PASS |
| returned / missing / shuffled / reversed / conflicting states supported | PASS |
| segment coverage delta exposed | PASS |
| segment return contribution exposed | PASS |
| affected atom IDs exposed | PASS |
| receipt line exposed per segment | PASS |
| JSON remains inspectable | PASS |
| false clean closure still blocked | PASS |

## Notes

The UI uses a compact HTML segment strip plus a selectable segment inspector. Metric cards summarize; the segment ledger localizes motion-route breaks; the receipt explains settlement. This keeps the HF demo fast while making route support inspectable without hiding the account in JSON.
