MT-2 and MT-3 remain untouched; the branch closes without changing traffic strength or predictor schedule. +A post-failure training-only audit performs no validation or test evaluation +and stops at the first training-active nonfinite tensor. The first failures are +the stem forward weight and its momentum at task step 23 for raw, 69 for +norm-matched raw, and 74 for innovation. The predictor slope and reciprocal +feedback weights remain finite at those points. Norm matching and innovation +therefore delay the same multiplicative local instability rather than remove +it. `THEORY.md` derives the linearized residual-coupling term `D W C` and shows +why residual RMS alone cannot certify stability. + ## MT-2: frozen full validation gate Copy MT-1 exactly for 200 epochs.
