Phase 1 group 2 (L27, L26, L28, S21, L13, ST6, S20). - L27: fixed_buffer.hpp + its test + the CMake entry — no consumers. - L26: dislike_multiplier_ and its doubling/halving bookkeeping — upstream InterfaceRL residue that drove nothing. The audit pointed at the wrong test file for the surviving reference; the actual assert was in test_mlp_geo_dislike.cpp:211, removed here. - L28: added copy_weights_to(std::span<float>) to FixedStorage and DynamicStorage and switched feedback.hpp's take_snapshot/push_undo/nudge to it. Drops the permanent whole-net flat_ scratch buffer from FixedStorage and the per-gesture double copy. Behaviour-identical: same source values, same write order, same RNG draw order in nudge(). - S21 + L13: deleted NISPS_AUDIO_MEM / NISPS_APP_SRAM / NISPS_AUDIO_FUNC — zero use sites outside perf.hpp and comments — and rewrote midi_io.hpp's one misshapen NISPS_AUDIO_FUNC use as a plain `inline void`. perf.hpp now documents only the inlining/hotness macros that actually exist, and audio_driver.hpp no longer claims an SRAM discipline the code never had. - ST6: feedback.hpp's header now describes the four current modes and the Geometric default, dropping the retracted "geometric push NOT ported" claim. S20 — OPERATOR DECISION (§7.1): the four legacy feedback behaviours (RandomiseOutputs, RandomiseMlp, AvoidStyle::Diffuse, the RandomiseMlp branch of on_drag) are KEPT, not deleted. They are wanted as building blocks for experimenting with how different instruments feel under different behaviours. Each is now marked at its definition as deliberately-retained research reserve so future audits stop flagging it as dead code. L25 (the 16 KB firmware loss-history buffer) is NOT done here — see the phase report; it turned out to be coupled into the shared mlp.hpp, and its fate belongs with the browser telemetry build (§7.3 / plan §6.5e). Gates: run-all-tests.sh ALL GREEN. |

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).
