# 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. Existing retained outputs are oracles, not a substitute for the missing self-contained canonical input fixtures recorded in `NUMERICAL_CONTRACT.md`.
