v0.1

What this edition identifies

• The deterministic simulation rules recorded in portable replay documents.
• The matching Observer runtime used for exact historical playback.
• A version label that the D1 published rules catalog may bind to allowed integrity fingerprints.

The label is not a hard-coded submission allowlist. Check the live published rules catalog for current acceptance.

Integrity boundary

A replay must carry an explicit game version, a self-consistent rules snapshot, a deterministic action trace, and a matching result checksum. Ranked Challenge certification additionally requires a valid one-use ticket and exact private re-simulation.
