Dual Run Hash Match
Dual-run hash output is preserved as reviewable evidence.

What you are seeing
Scene
A proof-oriented scene showing how determinism is surfaced to buyers and reviewers.
Why it matters
Expose deterministic hash comparison as a visible proof artifact, not a hidden internal check.
Pass condition
Run 1 and Run 2 hashes should match in the repeated-run lane.
Proof views
Use Public proof for the clean buyer-facing read, Event focus for adaptive slowdowns around the key moment, and Debug proof for contact cues, overlays, frame numbers, and proof-lane instrumentation.

Systems exercised
- CRC64 state hash
- proof scripts
- artifact capture
Known limitations
- Does not by itself certify universal cross-platform parity.
Recommended context
Ideal for trust-building when a reviewer wants proof artifacts rather than marketing copy.
Determinism status
- same build: expected
- cross-run: explicit proof target
- cross-platform: not guaranteed
- snapshot / restore: related but separate
