Replace the vendored runtime MLP in vcv/src/iml.hpp (DetRng + 3D-weight-store
MLP + Dataset + IML) with a THIN, Rack-free adapter over the shared core:
nisps::ml::MLPCore<nisps::ml::DynamicStorage> (8->[16,24,16]->16, the P2 dynamic
case), nisps::Rng, and the core MLP's own FIFO dataset. Behaviour changes from
the vendored approximation to core-exact firmware/WASM semantics.
- MEMLNaut.cpp: staged/pending weight buffers and patch JSON now use the core's
flat [weights..][biases..] vector (nisps::IML<float>::Weights); patch version
bumped to 3. Double-buffer / single-writer threading discipline unchanged.
- New ctest tests/cpp/test_vcv_iml_parity.cpp: seeded train/infer/move_weights
session through the adapter is memcmp-equal to a bare MLPCore<DynamicStorage>.
- Docs: vcv-module.md delta #5 marked CLOSED (2026-07-18); MAP.md vcv/ updated.
Closes vcv-module.md delta #5.
