Phase 1 group 4 (S33, S34, L54).
- S33: removed 12 dead entries across the full 5-layer registration chain
(bindings.cpp KEEPALIVE -> EXPORTED_FUNCTIONS -> the NispsModule declaration
table -> the WasmIML wrapper -> the EngineApi facade): nisps_ml_reset,
example_count, move_weights, feedback_learning_paused, feedback_drag,
jolt_lr_scale, jolt_tick_lr_ramp, pipeline_state_size/save_state/load_state,
feedback_placing and feedback_state. Each was grepped against manifold/src,
manifold/tests, the e2e specs, manifold/tests/wasm-load.ts and
tests/cpp/parity_wasm.mjs — the parity gate builds its own API via cwrap and
is a real consumer, so it counts.
KEPT deliberately: EXPORTED_RUNTIME's heap views + ccall/cwrap (the parity
harness and wasm-load.ts depend on them), and nisps_ml_feedback_static_output,
whose C export IS called directly by parity_wasm.mjs even though no TS
wrapper reaches it. Also dropped parity_wasm.mjs's moveWeights cwrap, which
was declared but never invoked.
- S34: deleted the publishWeights_ channel — EngineSink.setWeights,
Spine.setWeights/weights()/liveWeights and every call site. It ran a C->heap
copy plus a fresh Float32Array allocation at up to 200 Hz into a field
nothing read. getWeights survives for persistence and the debug probe.
- L54: worklet loader — deleted the unused imports object, the 'c' branch,
exMap and the duplicate second loop, and replaced the silent `() => 0` stub
with one that throws, so a missing import fails loudly instead of returning
plausible zeros into the audio path.
manifold/public/nisps.{js,wasm} rebuilt with the trimmed export list (emcc
3.1.69, the CI-pinned version) and committed — the freshness gate added in
Phase 0 requires it, and the webhook ships this artifact to production.
Gates: run-all-tests.sh ALL GREEN, parity 1273 floats within 1e-5.
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).
Adds the Manifold app (manifold/) — the convertible-mode React front-end on
the real NISPS ML+audio engine, served live at meml.lnfinitemonkeys.org/next/.
Console chrome trimmed per UI pass:
- drop mode label + subtitle from the top-left overlay (keep MEMLNaut wordmark)
- remove the composite split preset/ratio readout (top-centre)
- remove the OUTPUT corner tag above the bars
- remove the A/B compare toggle from the verdict cluster
- remove the follow button + input/noise readout (bottom-left)
- remove AltitudeNav focus switcher (bottom-right)
