Operator-approved ABI change (P2 stop-point). The WASM MLP is now MLPCore<DynamicStorage>: - nisps_ml_create(input, output, hidden[3], n, seed) honours its args; non-positive/null fall back to the historical 32→[10,14,18]→126, so every pre-P2 caller (manifold, worker, parity harness) stays bit-identical. Invalid/oversized dims (>4096) → null. - NEW nisps_ml_reshape(ml, in, out, hidden, n, spread): fresh net at the new dims, warm-started via nisps/ml/warm_start.hpp (overlapping region copied; rest keeps spread init); feedback controller re-created (state resets — reset-on-reshape modal is the front-end contract). Failure leaves the old net untouched. - nisps_ml_describe(ml, out): takes the handle; null reports defaults. - FeedbackController got the same storage split: algorithms in FeedbackControllerCore<FbStorage>; FixedFeedbackStorage keeps firmware/ tests source-identical via the old alias; DynamicFeedbackStorage (one arena) sizes to the runtime net. Firmware .text unchanged (122692). - MLHandle: per-instance scratch vectors; dropped the dead 2MB batch_out_scratch. - TS: types.ts decls (+_nisps_ml_reshape), wasm-iml re-describes the created instance, worker carries a shape-contract note for P2.3. Verified: ctest 4/4 incl. new warm-start grow/shrink test; reshape ABI smoke (dims honoured, overlap survives, invalid rejected, outputs bounded); parity PASS unchanged (2.4e-7); lint clean; manifold 9 unit + 20 e2e green; firmware .text 122692 (+0.30% vs pre-P2 baseline).
