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). |

Neural Interactive Shaping of Parameter Spaces

Firmware
The hardware firmware targets the MEMLNaut RP2350 build and uses repo-local helper scripts for the known-good build configuration:
git submodule update --init --recursive
scripts/build-firmware.sh
scripts/flash-firmware.sh
scripts/build-and-flash-firmware.sh
Notes:
- The scripts build for
rp2040:rp2040:solderparty_rp2350_stamp_xlwithOptimize3. - The build forces C++20 because the firmware uses
std::spanand concepts. build-firmware.shaccepts an optional variant name such asMEMLCeliumorBreakOr. Matching remains case-insensitive, somemlceliumstill works. If you omit it in an interactive shell, the script parsesMEMLNaut-NISPS.ino, prompts for a variant, and rewrites the activeMEMLNAUT_MODE_TYPEbefore building.flash-firmware.shaccepts an optional mountpoint argument, or auto-detects common UF2 bootloader mounts such as/run/media/$USER/RP2350and/run/media/$USER/RPI-RP2.
Manifold (browser app)
Try NISPS in your browser — no hardware required. Manifold is the React front-end running the same C++ engines + ML as the firmware, compiled to WASM:
cd manifold
bun install
bun run dev
Staging deployment: https://meml.lnfinitemonkeys.org/next/
Train a neural network to map input gestures to synth parameters through interactive machine learning: place examples, or use verdict-based feedback (explore-and-place, geometric dislike).
