RELAUNCH DEPT.AI-BOOST CHALLENGE 4 / BOUNDARY PROTOTYPE
ScenarioReceipt / 0.1.0Synthetic data only

Crash evidence in.
Inspectable scenario out.

A crash-to-validation boundary that keeps provenance, uncertainty, deterministic checks, catalogue coverage, and the final decision in one reviewable receipt.

Honest prototype boundaryNo real crash database, generative extractor, automotive accuracy, ASAM compatibility, or safety certification is claimed.

THE DECISION CONTRACT

One boundary between model output and engineering use.

  1. 01

    Bind evidence

    Every populated attribute points back to a stable source identifier and field path.

  2. 02

    Preserve uncertainty

    Missing speed remains unknown. The boundary never invents a convenient range.

  3. 03

    Validate independently

    Deterministic range, schema, privacy, and consistency gates control promotion.

  4. 04

    Explain coverage

    Catalogue candidates expose each matched and unmatched constraint, not only a score.

  5. 05

    Seal the decision

    A canonical SHA-256 receipt makes later changes to evidence or output detectable.

AWAITING LOCAL RUN

No decision exists yet.

Select a synthetic evidence state and build the receipt. The browser performs the calculation locally and sends no data.

This interaction demonstrates the deterministic acceptance boundary only. It does not extract from real reports, call a model, assign crash fault, or certify a scenario for safety use.

FIVE-MONTH ADVANCE PATH

The missing work stays visible.

NOW

Deterministic boundary

Synthetic fixtures, evidence references, uncertainty states, validation, catalogue matching, and stable receipts.

NEXT

Licensed source adapters

Two open European accident sources, a versioned scenario schema, data cards, and a labelled baseline.

ADVANCE

Constrained extraction

Disclosed LLM/VLM extraction, calibration, kinematic gates, expert review, and simulation-oriented export.
