Four items from one workflow, committed together because their build and CI
wiring genuinely interleaves — nisps/CMakeLists.txt, run-all-tests.sh and
ci.yml each carry hunks from two of them, and the stage renumbering (1/5 ->
1/6) touches every line. Splitting would produce commits that do not build,
which is worse than a commit that does four things and says so.
S26 part 2 — the curve declaration now matches reality. params[].curve stays
the mode-wide DEFAULT; a voice_spaces entry may now be {name, curve_overrides}
declaring only the slots where THAT voice space deviates. The 6 modes with one
voice space are byte-identical. The values were derived MECHANICALLY by a new
codegen/curve-audit.ts that models the four idioms a p[N]*p[N] regex misses
(alias form, memlcelium's implicit-counter sq() lambda, loop-generated indices,
smooth_params_), inlines helpers, and RAISES rather than guessing when it
cannot reduce an expression. A drift gate cross-checks 1179 (voice space x
param) slots against engine source on every run and was proved to fail loudly
on three drift classes. Application stays in the engine: nisps/engines,
nisps/pipeline and nisps/core are untouched, generated output is pure insertion
(755 insertions, 0 deletions), and the rebuilt nisps.wasm was byte-identical.
S4 / 7.2 — firmware reads the active mode's driver config at mode start, and
mic/line is real. My brief assumed the engine owns this; the code disagreed and
the code was right. sound_analysis_midi's EngineT is NoOpEngine — the mic lives
on a separately-composed AnalysisEngine member — so engine-level wiring would
have compiled, passed every gate, and left the one mic mode on line input.
Hence a mode-level seam defaulting to engine().driver_config(). Separately,
DriverConfig's defaults (line_level 0, output_volume 1.0) had drifted from
memllib's actual 3/0.8 because nothing had ever read them; wiring them as-is
would have made every silent mode louder and its line input maximally
insensitive — a behaviour change disguised as plumbing. Now pinned by a test.
Also: GetSysClockSpeed() panic()s on unsupported sample rates and runs on the
first line of setup(), so sample_rate needed a fallback ahead of clock setup.
CI's firmware env list gains soundanalysismidi — it is the only mic variant and
nothing else compiles that path.
Plan 5e — telemetry is real. A loss_history C-API entry across the full 5-layer
chain lets the browser read the per-iteration loss the core already records.
The audit named one fabrication site; there were two — wasm-iml.ts's
synchronous train() published lossHistory: [loss] as well. A third, ctx.loss,
was not merely dead but actively synthetic (fallbacks of prev * 0.82 and a
literal 0.5, rendered by nothing) and is deleted. The firmware buffer stays
untouched, per the L25 call. EngineApi.lossHistory() reads spine state rather
than the MLP handle, because trainAsync() fits on the worker's mirror net and
the handle would give a subtly-wrong second answer.
Plan 5f — engine throughput is measurable. One source compiled twice (CMake
natively, emcc for WASM) so the targets compare directly and no WASM export is
added. Sequencers are driven into a working state, and every row prints its own
working-state evidence so a number produced by an idle engine is visible rather
than plausible. Reports, never asserts: a wall-clock threshold on shared
hardware is meaningless or flaky, same call as the firmware size job.
ALIGNMENT: the telemetry defect is deleted (built, not deferred); the
performance defect is rewritten to what is actually left — these are HOST
numbers, and nothing measures the RP2350 at 150 MHz, which is the target the
mission's constraint is about. Q4 (memllib ownership) and Q5 (legacy feedback
modes) are closed.
Corrections to my own earlier claims, both found by agents contradicting the
brief: manifold/ONBOARDING.md was NOT "now accurate" — its primitives list
still named five deleted primitives and cited a seededGradient() that does not
exist. And the parity harness misses the sequencer engines because it runs 128
frames while their sequencers evaluate every 400-500 samples, NOT because
all-params-0.5 fails to trigger them (it does trigger: 0.5 maps to ratio 2,
firing three times per bar). The fix is a longer window, not different params.
Gates: run-all-tests.sh ALL GREEN — 4/4 ctest, parity PASS, lint clean, curve
drift 1179 slots ok, 39 e2e (was 33). Firmware: 5 envs built including the mic
variant.
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)
