# Holographic Trace Stack Reassembly Harness

**Stack the traces. Reassemble the account.**

Version: **v0.2.0**

This is a standalone Hugging Face Gradio Space proof harness for testing whether atomized source traces can be stacked midstream to reassemble a coherent, honest account of a source.

## Boundary

This is **not optical holography**.

This is **not a 3D hologram**.

This is **not a cinematic visual engine**.

This is **not a live mycelium/geometry renderer**.

The phrase **holographic dataset** means one trace object can be projected through multiple accountable views:

- source view
- atom view
- timeline view
- object continuity view
- motion route view
- pressure state view
- receipt view
- reassembly view

The harness does not claim full source truth. It evaluates trace support, route integrity, source-return, boundary respect, and receipt quality.

## Core thesis

If a source is atomized into trace-bearing components, and those traces preserve enough relational structure, then the system can stack the traces midstream and reassemble a coherent account of the source without relying on the original surface form alone.

## Core route

```text
source
→ atomization
→ trace capsule
→ holographic dataset
→ trace stack
→ midstream reassembly
→ reprojected dataset
→ receipt
```

## v0.2 update

v0.2 keeps the v0.1 bounded synthetic proof harness stable and adds a scoped forensic layer for live inspection:

- per-contribution score breakdown
- weighted support panel
- compact motion-route segment ledger
- color-coded route statuses
- segment-level coverage and return contribution
- affected atom IDs
- receipt-facing reason line for each segment

The new motion-route ledger converts `motion_route_score` from a single number into an inspectable route-integrity map.

Segment states:

- `returned` — motion segment points back to the expected prior frame/object state
- `missing` — expected motion atom is absent
- `shuffled` — stack order or return route is out of expected sequence
- `reversed` — route direction is inconsistent
- `conflicting` — source/hash identity conflict touches the segment

Color convention in the UI:

- green = returned
- amber = shuffled / reversed
- red = missing / conflicting

## What the harness proves

The harness starts with controlled synthetic sources rather than arbitrary user video. This gives ground truth and makes the proof measurable.

Synthetic examples include:

- moving circle
- moving square
- color changes
- frame order
- object identity
- motion path
- optional occlusion
- optional missing frame

The source is atomized into trace packets:

- frame atoms
- object atoms
- edge / shape atoms
- color atoms
- motion atoms
- time atoms
- source-return atoms
- receipt atoms

## Required tests

The built-in validation runner executes all six required tests:

1. `FULL_STACK_REASSEMBLY`
2. `PARTIAL_STACK_REASSEMBLY`
3. `SHUFFLED_TRACE_TEST`
4. `MIXED_SOURCE_FALSE_STACK`
5. `ROUND_TRIP_TEST`
6. `CROSS_PROJECTION_TEST`

## Metrics

The cockpit reports:

- `source_return_score`
- `trace_completeness_score`
- `temporal_continuity_score`
- `object_continuity_score`
- `motion_route_score`
- `reassembly_confidence`
- `false_settlement_risk`
- `pressure_state`

v0.2 also exports:

- `contribution_breakdown`
- `motion_route_diagnostics`
- per-segment coverage delta
- per-segment return delta
- per-segment weighted contribution
- per-segment receipt line

## Pressure and boundary states

Possible states:

- `HELD`
- `REASSEMBLED`
- `STRAINED`
- `REPAIRING`
- `CONFLICT`
- `QUARANTINED`
- `MUST_STOP`
- `CLOSED_FOR_CURRENT_SCOPE`

The system must not falsely claim clean reassembly when trace support is incomplete, shuffled, mixed, missing, or corrupted.

## Files

Required Hugging Face Space root files:

- `app.py`
- `requirements.txt`
- `runtime.txt`
- `README.md`

Additional release files:

- `VALIDATION_REPORT.json`
- `VALIDATION_REPORT.md`
- package `.zip`
- package `.sha256`

## Local validation

Run:

```bash
python -m py_compile app.py
python -c "import app"
python - <<'PY'
import app
report = app.run_required_tests()
print(report['required_tests_run'])
print(report['summary'])
PY
```

Expected: all six tests run and return explicit receipt-bearing states. Partial, shuffled, and mixed-source conditions should mark strain, repair, conflict, quarantine, or refusal rather than false closure.
