- plan P2 marked landed (hardware timing spot-check deferred to the
chokepoint-B session on physical MEMLNaut)
- ALIGNMENT: defect #3 resolved by the runtime-shaped browser MLP
- MAP/AGENT-REFERENCE/nisps-wasm-README: describe the honoured-dims
create + reshape ABI; note per-mode dims become schema-real at P5
- fresh wasm artifacts from the gate run
Wire the runtime-shaped WASM MLP (one-core-engine P2) through the manifold:
- WasmIML.reshape(dims, spread): calls nisps_ml_reshape, re-describes the
instance, reallocates every dim-dependent heap buffer, refreshes weightCount,
clears the TS Dataset mirror (C-side resets), drops the stale training worker,
and pushes the new shape through the sink.
- EngineApi.reshape exposes it and re-ticks the spine so outputs/audio reflect
the new net. Spine already tolerates the arity change (buffers resize, version
bumps); documented.
- Training worker protocol carries the current hidden dims; the worker
ensureNet()s its mirror net to match after a reshape.
- ConsoleApp offers the reshape behind ReshapeModal on an active-layout CHANGE
(never on load; default 32-input over-provisioned head + zero-padding
preserved when declined). British copy, reset-on-reshape.
- Drawers: delete the stale even/odd blending note; honest dedicated-dimensions
line + net-arity chip.
- Probe: __nisps.reshape(nIn) / .describe(); e2e reshape.spec (default 32/126,
reshape to 4, describe reports 4, bounded outputs, weight count 3148→2868,
spine still propagates). All 25 e2e pass (20 existing + 5 new).
- ONBOARDING: refresh the reshape status + stale hardwired-arity gotcha.
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).
Algorithms (forward, backprop/SGD, init, move_weights, diagnostics) now live
once in MLPCore<Storage> (nisps/ml/mlp.hpp). Storage models:
- FixedStorage (storage.hpp): template-sized std::array, zero heap. The
classic MLP<NIn,H1,H2,H3,NOut,...> is an alias preserving kInput/kHidden*/
kOutput/kNumLayers/weight_count() constexpr — firmware + bindings + modes
compile unchanged.
- DynamicStorage (dynamic_storage.hpp): runtime dims, ONE arena allocation
at construction, nothing per-call. #error under NISPS_TARGET_EMBEDDED
(new macro in core/perf.hpp); sole lint-cpp.sh heap-allowlist entry, plus
a lint check that fails if the #error guard disappears.
Verification:
- new ctest test_mlp_storage_parity: fixed↔dynamic BIT-identical across
init/draw/inference/train(FIFO)/move_weights(pin mask)/eval_loss/
layer_stats/set_weights/infer_batch/reset; invalid+moved-from inert
- golden ML vectors (pre-refactor constants) pass → bit-stable refactor
- native↔WASM parity PASS, max delta unchanged (2.4e-7)
- chokepoint B compile: PAFSynth .text 122324→122692 (+0.30%, ±1% budget);
RAM +416B (eval scratch)
- fix: firmware-common.sh used bare 'python' (absent here) → ${PYTHON:-python3}
Part of one-core-engine-refactor P2. nisps_ml_create ABI untouched (P2.2 is
an operator stop-point).
The recorded 4733ca0 was unfetchable ('not our ref') and the tree has been
built against b37fc53 (feat/nisps-core-swap) since June. NOTE: b37fc53 is
not on the memllib remote either — fresh clones still need the MAP.md
gotcha; pushing feat/nisps-core-swap to a reachable remote is the real fix
(operator decision, flagged in session report).
Bring the two playground-only exploration UIs into manifold ahead of the
playground's retirement (one-core-engine refactor §P1):
- Jolt: press-and-hold continuous weight-morph, release to freeze.
- Explore: Ornstein-Uhlenbeck exploration intensity on the output vector.
Interim TS maths ported verbatim from the retired playground modules
(engine/jolt.ts, engine/ou-explore.ts). The ExplorationController
(engine/exploration.ts) is the single P3 swap boundary: it drives Jolt via the
existing EngineApi get/set-weights + process route, and OU via a new inert-by-
default output-morph hook on the spine. In §P3 only that module changes to call
nisps_ml_jolt_press/release + nisps_ml_explore_intensity.
UI lands in the Learning drawer (Jolt hold-button + Explore slider), monochrome-
consistent, British copy. Gates green: typecheck, build, Playwright smoke.
Migrate the specs worth keeping from playground/tests/e2e (retired in P1) into
manifold/tests/e2e, adapted to Manifold's probe surface:
- probe-api.spec.ts: the window.__nisps debug-probe contract (ready, bounded
outputs, example count, randomise, setInputs inference, thumbsUp/Down,
addExample, train loss non-increasing, async train, clearExamples, evalLoss,
inferBatch, getLayerStats, getWeights). Retargeted to MLP<32,10,14,18,126>
(weight_count 3148) and Manifold's direct addExample/routedOutputs surface;
dropped the playground's __init/iml-poke escape hatches and stream-pending
skips.
- spine.spec.ts: the spine invariant — setInputs -> processed -> ml -> routed
yields bounded, consistent routed outputs; the probe stays alive across dock
output-mode switches (driven via the real selector UI, replacing the
playground's localStorage-reload mode cycling).
- helpers.ts: loadProbe(?debug=1 + cleared storage + __ready wait), settleInputs
for EMA convergence, bounded/changed assertions.
Dropped playground UI specs (ui-interactions, persistence, mode-registry list)
that die with the playground chrome. No probe.ts changes needed.
Records canonical gesture trace, curve catalog samples, and input/output
pipeline outputs from the current TS implementations, plus a bun-test drift
guard that re-runs them against the fixtures within 1e-9. Serves the P4
one-core-engine gate: same pointer trace -> same routed output pre/post the
C++/WASM migration.
- Double-click the input mark to enter follow-mouse mode: a window-level
pointermove listener maps the whole viewport onto the surface's [0,1]²
space so the knob tracks the cursor across the entire UI. Esc or a second
double-click exits; a badge + hidden cursor signal the active state. Local
pan/long-press and auto-drift are suppressed while following.
- Keys 1 = thumbs-down/explore (perturb), 2 = thumbs-up (commit), on the
window keydown handler so they fire even in follow-mouse mode. Drawers
learn/inputs lose their 1/2 shortcuts (3-5 keep route/settings/help).
- Sync help keymap (Drawers) + ONBOARDING stages table.
Geometric-dislike ('Push away', Mode 1) is now the default feedback mode
instead of explore-and-place, which works poorly. Add a Clear button to
the Learning drawer that forgets all recorded examples and wipes the
on-map visuals (feedback markers + placed-anchor pins) via the existing
ctx.onClear, now also resetting pins.
The on-screen circular input disc let both the mouse and the gamepad drive
the knob outside the visible circle.
- Gamepad: each stick axis was clamped to [0,1] independently, so a full
diagonal push reached the square corner. Clamp the stick *vector* to the
unit disc (radially symmetric) before mapping to [0,1]; covers both sticks.
- Mouse: the circular variant clamped in normalised [0,1]^2 but the canvas
drew the knob across the full non-square panel against the inscribed circle,
so the disc rendered as an ellipse that spilled past the rim. Map both the
pointer and every drawn position (knob/pins/markers/trail/flash) through the
inscribed-circle geometry, and disc-clamp the auto-drift.
Add a "grab → move → drop" gesture that moves an existing positive
example's output to a new input position, preserving the output. This is
the new core's home for upstream InterfaceRL's drag-store/reposition-commit,
distinct from Explore→Place (which places newly-auditioned scratchpad sounds).
- nisps/ml/feedback.hpp: begin_reposition()/commit_reposition()/repositioning().
Reuses the Placing state (static_output holds the carried vector) but a
reposition_ flag makes commit AND the mode-switch teardown SKIP the weight
restore — the real net is never set aside here, so restoring snapshot_ would
clobber the live trained net. Guards cancel_place + abort_explore_place.
- firmware glue: state-gate Toggle B. Exploring → reroll/nudge (unchanged);
Idle → MomB1 grab, MomB2 drop (commit + add_example + train). The 4D variant
has no joystick button, so the gesture lives on the momentary toggle. Also
fix a stale top-of-file control-map comment that contradicted the bindings.
- tests: 4 reposition cases (hold without snapshot; commit stores carried
output with no restore; mode-switch aborts without clobber; begin-only-Idle).
- MAP.md: document the full ExploreAndPlace lifecycle + reposition wiring.
Audio-hold (carrying the sound audibly during the move) remains the existing
unwired static_output() TODO and affects Explore→Place identically.
Firmware compile unverified (no arduino-cli); host tests + lint pass.
Consolidate docs/slp-workshop/SPEC.md into docs/specs/slp-workshop-
firmware.md so the project has a single SLP-Workshop spec. The unified
spec is now two parts:
- Part I (§1-8, shipped/stable): the mode + Jolt & OU-explore gestures.
- Part II (§9-13, planned): the output-mode evolution — Continuous/Rhythm
stream model, gate sequences, CV/MIDI output config, Manifold UX, and
the locked operator decisions (2026-06-28).
Frontmatter bumped stable -> evolving (the doc now spans shipped +
planned). Donor docs/slp-workshop/SPEC.md removed; README.md row and
MAP.md ## Specs note updated. No code change.
The painter's-algorithm sort was descending, but z2 (depth) increases
toward the camera in both the top-down and tilted-from-above views, so
nearest was painted first (underneath). This showed the last layer on
top in the default top-down view and made the stack occlude inside-out
when tilted back. Sort ascending: farthest first, nearest last.
Self-contained stable reference spec crystallizing the SLP-Workshop
firmware: the MEMLCelium-based mode, the two adaptive-learning gestures
ported from upstream InterfaceRL (Jolt held weight-morph, OU output
walk) with exact constants, the runtime-not-compile-time + inert-by-
default design, the ModeBase integration incl. the GCC -Wstringop-
overflow workaround, control mappings, schema/codegen, and the
browser-parity caveat. Adds the spec to docs/specs/README.md and a
## Specs section to MAP.md per the specs-skill config format.
Refs commits 4e60d01, 57c9ede (merged at 527b8fc).
Spec-only (firmware fork is WIP, built by another agent). Captures: memlcelium
is a single shared-net hybrid (14 ratio-seq + 42 synth outputs); the two-stream
model (Continuous + Rhythm); firmware 3 compile-time modes + browser's 4th
split-net hybrid; gate-sequence config for CV & MIDI (counts + shared/separate
net toggle; XY-pad→2nd pad / gamepad→double-stick); CV jack allocation
(11 CV + 3 gate, swap CV→gate); RatioSeq gate generation; no wire-protocol change.
Restores the April-2026 "uSEQ-Celium" functionality (browser → uSEQ
hardware + CV expander over USB Web Serial) as a first-class Manifold
Outputs backend, and re-vendors the RP2040 firmware into the repo.
- protocol v2 (uSEQ-CV): firmware/useq-celium/shared/protocol.h is the
single source of truth, mirrored by manifold/src/backends/useq-protocol.ts.
26-byte OUTPUT frame, 11×u16 CV (12-bit) + 3-gate bitfield + XOR; fixed
topology; host-agnostic so the MEMLNaut RP2350 can emit identical bytes.
Spec in docs/useq-celium/protocol.md.
- firmware/useq-celium/{main,expander}: PlatformIO RP2040 firmware rewritten
to v2 from the real April pin maps (expander I2C addr 0x10).
- UseqCvBackend (id cvgate): Web Serial connect/identify/disconnect, 100 Hz
stream, per-channel dead-zone, gate thresholding; modeled on midi-backend.
Per-output CvSpec (channel + gateThreshold) on MFParam; config UI in
OutputsBackendConfig + BackendAdvanced; new "CV / uSEQ" top-dock mode.
- bun-test for the protocol frame layout; MAP.md updated.
Playground parity for the two learning gestures, TS-only (reuses the
existing nisps_ml_get/set_weights bindings; no C++/wasm change):
- playground/src/ml/jolt.ts — TS port of nisps/ml/jolt.hpp.
- playground/src/output/ou-explore.ts — TS port of nisps/ml/ou_noise.hpp.
- mode-runtime.ts — jolt (~200Hz weight-morph timer via mlStore weights)
+ explore (OU stage in recomputeOutputs, ~30Hz roam timer). Both inert
by default and cleaned up on unmount, so other modes are unaffected.
- SLPWorkshopMode.tsx — hold-to-Jolt button + Explore slider.
Uses Math.random() (documented); stochastic exploration aids don't need
firmware-parity. Verified: playground tsc --noEmit clean.
The OutputEditor popover was placed with a fixed top + an index-based
left/right heuristic and never measured the viewport, so it clipped the
screen edges when the window wasn't full-screen. It now measures its
anchored rect on layout and translates itself back inside the viewport
(8px gutter), re-checking on resize.
Single-file map of the Manifold front-end so an agent can make a tweak/fix
without re-grepping the tree or reading the 40KB design specs: run/build/
deploy/test commands, the three-layer architecture (UI / engine spine / WASM),
the convertible Stage system, the Dock + drawers, engine/inputs/feedback/
backends layout, and the non-obvious gotchas (imperative output reads,
baseURI asset URLs, hardwired WASM arch, curves↔C++ lockstep, no 'C15').
New SLP-Workshop firmware variant (Synth Library Portland), built on the
MEMLCelium engine + MLP shape. Ports the two post-fork learning-algorithm
changes from upstream memllib InterfaceRL into the shared nisps/ml core,
runtime-configurable (no compile-time switch), inert by default:
- nisps/ml/jolt.hpp: Jolt — held continuous weight morph over the flat
weight buffer + post-release LR ramp (kJolt* constants verbatim).
- nisps/ml/ou_noise.hpp: OUNoise<N> — Ornstein-Uhlenbeck exploration walk
on the output vector (theta=0.02, dt=0.001, kMaxAmplitude=0.65).
Both wired into ModeBase so every mode gains jolt_press/jolt_release/
jolt_lr_scale + set_explore_intensity; gated so existing modes stay
bit-identical (parity + golden tests green). Firmware surfaces them on
TogB1 (Jolt) and RVX1 (explore). New SLPWorkshopMode mode + schema +
codegen; firmware alias + .ino variant; playground mode registration.
Tests: jolt + OU unit tests, ModeBase learning integration incl. an
inert-parity test proving SLP-Workshop == MEMLCelium with features off.
Verified: cpp tests, wasm build, native↔wasm parity, lint, codegen
golden, playground typecheck. Firmware compile/e2e/hardware are
environment-bound (no arduino-cli/submodules/browser here).
Refs ergo 019f0fca.
- mf-slider-input fill used calc(var(--mf-pct)*100%) but three consumers
(OutputControlRow held slider, OutputEditor, shared-ui Field) never set
--mf-pct, so the coloured track-fill stayed empty while only the native
thumb moved. Set --mf-pct inline on all three; harden the base class
(appearance:none + transparent bg + --mf-pct fallback + moz-range-progress).
- hide the two concentric noise-cap exploration rings around the input dot.
Fuse the /learn parameter-landscape sandbox into the main console:
- New SandwichStage: ports the 3D landscape renderer to React, driven by the
REAL EngineApi (inferBatch samples each output channel over the 2D input grid;
getOutputs feeds the live probe). Re-samples on engine version bumps; orbit
camera (top-down = flat 2D, tilt to reveal the stack), centred + grows to fill.
- Dock: new bottom toggle (SandwichIcon) → ctx.sandwich.
- ConsoleApp: when on, the sandwich replaces the centre stage in a 3-zone flex —
shrunken Manifold (left) · sandwich (centre, fills) · compact OutputStage
(right) — reusing pos/markers/verdicts. Opening it auto-closes the drawer so
the output zone is visible. Layers = the mode's params (capped 8).
typecheck + build green; verified headless (toggle on/off, sample, tilt).
Add glue/settings_view.hpp: wire_settings(mode) registers a "Joystick"
SingleSelectView on the MEMLNaut display carousel (TFT + rotary encoder, same
DisplayDriver as SystemView/SelfTest). For the 4-input two-joystick modes,
"Single" pins ML input channels 2,3 (the second joystick) to neutral via
ModeBase::set_input_pinned — the network is never rebuilt and trained state
survives toggling. Default is Dual. Only registered when input arity == 4.
Called from MEMLNaut-NISPS.ino setup() after addSystemInfoView(). MAP.md +
CLAUDE.md glue listings updated.
NOTE: compile-unverified — no arduino-cli/RP2350 toolchain on this host and no
hardware; needs scripts/build-firmware.sh + a flash test (chokepoint A).
Platform-agnostic neutral-pin mechanism (set_input_pinned/pin_value) on
ModeBase, lifted from ebb953a. Consumed by the firmware Joystick Dual/Single
settings menu; the browser fixed-MLP<4> half of ebb953a is superseded by main's
MLP<32> N-D input work and intentionally dropped.
Interactive /learn page rebuilt on the real NISPS engine (nisps.wasm):
- Stacked 3D landscapes = MLP output channels sampled over the 2D input grid
(the N-dimensional 'sandwich'); orbitable yaw/pitch camera, top-down = flat 2D.
- Three zones L→R: XY control (with +/- feedback markers) → MLP stack → output faders.
- Real training: push-away (feedback_down) + explore-and-place (enter/reroll/nudge/
commit), undo, randomise, nudge; landscapes re-sample and morph after each verdict.
- Params numberbox (1..8); new layers grow downward with the top slab pinned.
- Minimal-by-default with a discrete info switch revealing placeholder copy.
Standalone no-build page; loads ../nisps.{js,wasm}; deployed at /next/learn/.
The default (Particle) view no longer renders the 'MEMLNaut' wordmark
since the particle top bar became a heatmap strip; assert on the always-
present 'Learning' dock drawer label instead so the smoke test reflects
the current Console chrome.
Wire the modular input layer into the Console and reshape the browser
engine so input axes are genuine independent dimensions.
Inputs (manifold/src/inputs/):
- gamepad-source: emit press+release edges with standard-mapping labels
(enables hold-and-move); single/double-stick already present.
- midi-input-source: single-device selection + batch "MIDI Learn"
(every CC swept while armed becomes an axis); notes stay discrete.
- input-layer: compose() forwards each axis 1:1 (no mean-blend);
add onReducedInput so the manifold tracks gamepad/MIDI position.
- types: InputAction.phase, InputMode.
Console (manifold/src/console/):
- ConsoleApp: bind gamepad buttons to verdicts (RB up / LB down /
X randomise / Y nudge / B undo / A-hold reposition); mirror composed
position onto the manifold.
- Drawers: rebuilt Inputs drawer (source picker, gamepad legend, MIDI
device picker + batch-learn flow, learned-control meters).
Engine (nisps/wasm, manifold/src/engine):
- DefaultMLP widened MLP<2,..> -> MLP<32,..> (32 = MAX_AXES); each
active axis gets a dedicated slot, unused slots held at 0 (inert).
Rebuilt nisps.wasm (playground + manifold).
- spine/engine-api: setInputs writes the full N-D vector (was dropping
arr[2+]); primary pair keeps the 2-D pipeline; process() re-ticks the
whole vector via spine.reprocess().
Tests:
- parity_check/parity_wasm: ParityMLP -> 32 inputs, widen example bufs.
- CMakeLists: build parity binary with -ffp-contract=off so native
matches FMA-free WASM (training amplified the gap past 1e-5).
Inputs dock is still an exclusive picker; mixing toggles, reshape modal,
and the >2-D slider view (inputs-spec.md) are groundwork-laid but not
yet wired. See docs/redesign/midi-gamepad-inputs-worklog.md.
Replace the a-immersive original's clashing 20-colour palette (hot magenta,
lime, pink) with a ramp interpolated between Manifold's two brand accents —
--accent (#ff6a00) → --accent-2 (#00ccff) — softened to the app's semantic-
token saturation register so the strip reads as native chrome.
