# Tests

Future test layers, in order:

1. artifact and environment verification;
2. randomized aligned/ragged prepared-byte parity;
3. adversarial NaN, infinity, signed-zero, tie, and extreme-value behavior;
4. compute-sanitizer and deterministic repetition;
5. canonical attention and blocks 0/24/49;
6. two-step and canonical 12-step video/audio latent parity;
7. concurrent resident-service safety.

Canonical Q/K/V/output fixtures are now captured and reload-verified in durable
Phase 2A storage. Existing retained outputs remain additional oracles; executable
attention parity has not started.
