Phase 2 (S30, L52, L51). These are the gates that are supposed to protect the
core's headline constraints, so the fix is demonstrated rather than asserted.
- S30: lint-cpp.sh's heap audit hardcoded dsp/engines/ml/modes, so nisps/core/
and nisps/pipeline/ — the P4 control-rate hot path — were NEVER scanned. Its
comment handling also post-filtered with `grep -v ' *//'`, which misses
trailing comments. Coverage is now exclusion-based (everything under nisps/
except wasm/, tests/, build/), comments are STRIPPED before matching using the
same perl strip audit_float_suffix already used, and the pattern set is
extended. dynamic_storage.hpp remains deliberately allowlisted — it is a real,
documented heap user that #errors on RP2350.
PROOF (run by me, not just reported): planted `new float[4]` in
nisps/pipeline/input_chain.hpp plus a std::malloc in the trailing-comment form
the old filter skipped.
old lint: "[lint-cpp] clean", exit 0 <- the false negative, live
new lint: FAIL, both lines named, exit 1
Plants removed; lint clean and exit 0 again; tree verified unmodified.
- L52: parity-check.sh's FAIL branch was unreachable — under `set -e` the script
died at the diff command before it could print anything. A mismatch therefore
failed silently. The diff now runs inside the `if` condition, where set -e does
not apply. Verified by forcing NISPS_PARITY_TOL=0: old script exited silently,
new one prints FAIL with the exit code.
- L51: parity_check.cpp and parity_wasm.mjs headers documented 4 stages / blob
v1 against a real 7-stage / v5 implementation. Comment-only rewrite; parity
behaviour unchanged (re-ran the gate: PASS, 1273 floats within 1e-5).
Note for future work: the lint now permanently scans nisps/core/ and
nisps/pipeline/, so changes there are enforced that were not before.

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).
