Phase 1 group 5 (S15, S16, S18, S19, L22, L23, L20, L21, L1 delete-half).
- S15: the four-way focus/altitude system. setFocus was never called anywhere,
so only the 'composite' branch was reachable. Deleted SplitStage,
ReadoutStrip, InputMini, AltitudeNav, CompactAxis, the UI Focus type/prop,
the focus branches, stripPinned and the vacuous keyboard gates. MiniMeters
kept; engine.feedback.setFocus (a different, live thing) untouched.
- S16 + L1: the decorative stratum that rendered real-looking controls driving
nothing — A/B machinery, the fake seed, seededGradient + weightsRevision,
snapshots, master volume, bpm, and the learningRate/decay/tame/spreadLevel
sliders with their Drawers rows. Each was confirmed self-referential first.
NOTE a real behaviour change falls out of dropping `snapshots`: Undo outside
an active explore-and-place session used to pop a UI-only snapshot that
restored noiseCap/seed. It is now simply inactive unless a genuine
core-backed scratchpad undo exists. Geometric-dislike mode never had a real
undo primitive in the core, so only the fake path is gone.
- S18: BackendAdvanced.tsx and its Drawers block. It self-described as a
duplicate of the inline OutputsBackendConfig editor and BOTH rendered in the
same expanded drawer. OutputsBackendConfig already covers every backend.
- S19: pruned ConsoleCtx to the fields Dock/Drawers/OutputsBackendConfig
actually read; deleted the Axes type + axes/setAxis and the
preset/setPreset/offsetActive chain (permanently 'Sculpt'/false).
KEPT ctx.modes and ctx.setModeId despite having no reader today — the
Phase 5 instrument picker (§7.6, adopted) is built on exactly that plumbing.
- L22: the 5 dead primitives (Panel, StatusLine, ControlAxis, CurvePlot,
Sparkline) and their barrel exports, plus the now-dead .mf-axis-input CSS.
- L23: OutputControl/toOutputControl, ModeIconComponent and the BACKENDS
catalogue; Drawers now reads modeDesc.label/description from OUTPUT_MODES,
the surviving single catalogue.
- L20: the solo-mode selector's two unimplemented options no longer pretend to
be selectable.
- L21: FeedbackController vestiges — seed/undoDepth options, maxUndo, and six
ControllerEngine members nothing called (the finding named three; the other
three are used on the real EngineApi by debug/probe.ts, a different
interface, so removing them from ControllerEngine is safe).
Gates: run-all-tests.sh ALL GREEN (typecheck, 33 Playwright specs).
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.
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.
- 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.
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.
Route onMove through the XY-pad source's pushPad; instantiate useInputLayer
per engine and expose it on ConsoleCtx. The Inputs drawer now picks the
source(s) (XY pad / MIDI / gamepad toggles), configures each (gamepad
single/double stick; MIDI learn-map with per-binding clear), and shows the
composed channel layout + the blend-to-2 reshape notice referencing the
multi-WASM TODO (inputs-spec).
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)
