Iteration 01 of the GCM + O-information orthogonality-selection loop (S0–S5).
The de-leaked GCM/O-info decision code is certified bug-free at every decision boundary. Adversarially-hardened mutation oracle: kill rate 1.0 (201/201 non-equivalent mutants killed), 0 boundary survivors, 45 documented-equivalent excluded; self-check clean. Real-data fixtures, no synthetic data.
