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).
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.
Phase 1 group 3 (L3, L9, L4, L5, L6, ST1).
- L3: nisps/modes/voice_space.hpp — entirely dead, no includes anywhere.
- L4: deleted SawOsc and SquareOsc. KEPT SineOsc — a verifier caught that the
original reviewer's grep missed its live consumer (the firmware selftest);
re-confirmed here before touching the file.
- L9: removed the no-op VoiceSpace enum/table/setter boilerplate from the five
engines with no real voice spaces; kept it on PAFSynth, VerbFX and
ChannelStrip, which have real ones. Every engine member was checked against
nisps/wasm/bindings.cpp, firmware/ and tests/ for callers first.
- L5: ModeBase::input_dirty_ was write-only state — deleted the flag rather
than making it gate inference, which would have been a behaviour change.
- L6: VerbFXEngine's delay_to_verb_ (computed 12x per block, never read),
enable_reverb_, enable_delay_to_reverb_ and the unused set_enable_* setters.
- ST1: rewrote the four engine header comment blocks that described
implementations which do not exist.
L7 (MEMLCeliumEngine's inert feedback path) is deliberately NOT done — tracing
git history showed feedbackGain went 0.1f (live) -> "0; //0.1f" (explicitly
muted, value preserved) -> dropped entirely in the port. That is a muted
feature, not dead weight, and deleting it would silently lose it. Left intact
pending an operator decision; see the phase report.
Gates: run-all-tests.sh ALL GREEN.
Phase 1 group 2 (L27, L26, L28, S21, L13, ST6, S20).
- L27: fixed_buffer.hpp + its test + the CMake entry — no consumers.
- L26: dislike_multiplier_ and its doubling/halving bookkeeping — upstream
InterfaceRL residue that drove nothing. The audit pointed at the wrong test
file for the surviving reference; the actual assert was in
test_mlp_geo_dislike.cpp:211, removed here.
- L28: added copy_weights_to(std::span<float>) to FixedStorage and
DynamicStorage and switched feedback.hpp's take_snapshot/push_undo/nudge to
it. Drops the permanent whole-net flat_ scratch buffer from FixedStorage and
the per-gesture double copy. Behaviour-identical: same source values, same
write order, same RNG draw order in nudge().
- S21 + L13: deleted NISPS_AUDIO_MEM / NISPS_APP_SRAM / NISPS_AUDIO_FUNC —
zero use sites outside perf.hpp and comments — and rewrote midi_io.hpp's one
misshapen NISPS_AUDIO_FUNC use as a plain `inline void`. perf.hpp now
documents only the inlining/hotness macros that actually exist, and
audio_driver.hpp no longer claims an SRAM discipline the code never had.
- ST6: feedback.hpp's header now describes the four current modes and the
Geometric default, dropping the retracted "geometric push NOT ported" claim.
S20 — OPERATOR DECISION (§7.1): the four legacy feedback behaviours
(RandomiseOutputs, RandomiseMlp, AvoidStyle::Diffuse, the RandomiseMlp branch of
on_drag) are KEPT, not deleted. They are wanted as building blocks for
experimenting with how different instruments feel under different behaviours.
Each is now marked at its definition as deliberately-retained research reserve
so future audits stop flagging it as dead code.
L25 (the 16 KB firmware loss-history buffer) is NOT done here — see the phase
report; it turned out to be coupled into the shared mlp.hpp, and its fate
belongs with the browser telemetry build (§7.3 / plan §6.5e).
Gates: run-all-tests.sh ALL GREEN.
Phase 1 of the 2026-07 simplification audit, group 1. All verified dead by
independent grep across scripts/, .github/workflows/, codegen/, manifold/,
firmware/, vcv/, nisps/ and README.md before removal.
- S23 / L55: playground/ — only dist/ was tracked (1.2 MB of bundled JS,
sourcemaps and a second copy of nisps.wasm). The app itself is preserved on
branch archive/playground-solidjs and tag playground-solidjs-final.
- S29: the root Playwright rig — playwright.config.js, package.json,
package-lock.json and tests/e2e/. It served ./playground, a page that no
longer exists anywhere in the tree, and was invoked by nothing. NOTE: the
live suite is manifold/tests/e2e/ with manifold/playwright.config.ts, which
is untouched; every CI Playwright step runs with working-directory: manifold.
- L48: NISPS_CORE_EXTRACTION_PLAN.md + NISPS_CORE_TASKS.md (818 lines of
extraction relics; docs/specs/plans/ is the sanctioned home for plans).
- L36: data/ — two CSVs from a retired era, plus a tracked LibreOffice lock file.
- L32: .claude/worktrees/agent-ae87fe47/ only. The audit's wording invites
deleting .claude/worktrees/ wholesale; that would have been destructive —
the directory holds 12 LIVE registered git worktrees (332 MB), four of them
on branches with unpushed commits. Verified agent-ae87fe47 is NOT registered
before removing it; every live worktree is left intact. Cleaning up the rest
is a separate operator decision.
- ST10 fallout: dropped the dead `port-solidjs` branch trigger from ci.yml and
the dead `feat/manifold-mission` / `feat/vcv-dist` triggers from
vcv-plugin.yml — those branches are stale and the SolidJS target is retired.
tests/cpp/ is untouched. Gates: run-all-tests.sh ALL GREEN.
Third failure uncovered by the restored pipeline. With checkout and the C++
build fixed, CI reached the WASM step and died on `[build-wasm] emcc not found
at emcc`: ci.yml passed `EMCC: emcc`, but the script's existence check
(`[[ ! -x "$EMCC" && ! -f "$EMCC" ]]`) only understands paths, so it looked for
a file literally named "emcc" in the working directory. This has been broken
for as long as the override existed; it was invisible because CI never got past
checkout to run it.
Resolve a bare command name through `command -v` before the check, and drop the
now-redundant EMCC override in ci.yml — setup-emsdk already puts emcc on PATH,
which is what the script's own default looks for.
Verified by invoking it the way CI does: `EMCC=emcc bash scripts/build-wasm.sh`
now builds. Incidentally confirms the new freshness gate is sound — the local
toolchain is the same pinned emcc 3.1.69, and the rebuild reproduced the
committed artifact byte-for-byte.
run-all-tests.sh ALL GREEN.
First real signal from the restored pipeline: with checkout fixed, the cpp-tests
job got far enough to fail at `-Werror=stringop-overflow` in ring_buffer.hpp on
GitHub's GCC 13, a failure that had been invisible behind the broken submodule
checkout for a month. Reproduced locally against gcc 13.4.0 (local default is
gcc 14, which does not fire).
The warning is a false positive: GCC anchors the destination object to the
member at offset 0 and reports `buf_[head & kMask]` as writing past
`head_._M_i` (size 8) at offset [16, 268] — offsets that are precisely
buf_[0..63] of a 64-entry, 4-byte ControlEvent array. Adding an explicit
`__builtin_unreachable()` bound hint does not help, because the index range was
never what GCC got wrong. Declaring buf_ first anchors the analysis correctly.
Not a suppression, and behaviour-preserving: RingBuffer has exactly one
production user (ModeBase::events_) and is never serialized, copied, or sent
over a wire, so member order is unobservable. Reasoning recorded at the
declaration so nobody "tidies" the order back.
Verified: full ctest suite green under gcc 13.4.0 (the CI compiler) as well as
gcc 14.2, and scripts/run-all-tests.sh ALL GREEN (parity 1273 floats within
1e-5, lint, 33 Playwright specs).
Phase 0 of the 2026-07 simplification audit (plan §1). CI has been 100% red on
main since 2026-07-13 and every "gates green" claim since rested on local runs.
- S7 / critic gap 2: push memllib `feat/nisps-core-swap` (3 commits incl. the
pin b37fc53) to monkey-w1n5t0n/memllib and repoint .gitmodules at the fork.
Those commits existed on exactly one disk; `git ls-remote` now resolves the
pin, so `submodules: recursive` checkout and fresh clones work again. Drops
the compensating unreachable-pin error paragraph in build-firmware-arch.sh.
- S24 / S31: the manifold-tests job regenerates from schemas/, runs the codegen
golden test, and fails on a dirty diff — the "schema changes ship with both
generated outputs" rule is now enforced rather than assumed.
- S32: a WASM freshness gate runs the parity harness against the *committed*
manifold/public/nisps.{js,wasm} before the CI rebuild overwrites it. That
artifact is what the webhook ships to production, so a stale commit now fails
loudly instead of shipping.
- critic gap 3 / operator decision §7.4: the VPS webhook
(~/.config/webhooks/meml-deploy.sh, not in this repo) waits for the `CI`
workflow to conclude success on the pushed SHA before building. Fail-closed;
MEML_SKIP_CI_GATE=1 for an emergency hand-deploy. Verified the gate query
returns `failure` for fa37047, i.e. it would have blocked that deploy.
- S31: corrected run-all-tests.sh's false "single command CI invokes" header.
Docs moved with the code: ALIGNMENT defect 1 deleted (resolved) and the rest
renumbered; MAP.md's unreachable-pin warning replaced with the fork pin and a
pointer to the §7.5 vendoring decision; ONBOARDING documents the deploy gate
and the tracked-WASM-ships-to-prod hazard; plan §1 marked burned down.
Gates: scripts/run-all-tests.sh ALL GREEN (ctest 4/4, parity 1273 floats within
1e-5, lint, typecheck, 33 Playwright specs).
Replace the vendored runtime MLP in vcv/src/iml.hpp (DetRng + 3D-weight-store
MLP + Dataset + IML) with a THIN, Rack-free adapter over the shared core:
nisps::ml::MLPCore<nisps::ml::DynamicStorage> (8->[16,24,16]->16, the P2 dynamic
case), nisps::Rng, and the core MLP's own FIFO dataset. Behaviour changes from
the vendored approximation to core-exact firmware/WASM semantics.
- MEMLNaut.cpp: staged/pending weight buffers and patch JSON now use the core's
flat [weights..][biases..] vector (nisps::IML<float>::Weights); patch version
bumped to 3. Double-buffer / single-writer threading discipline unchanged.
- New ctest tests/cpp/test_vcv_iml_parity.cpp: seeded train/infer/move_weights
session through the adapter is memcmp-equal to a bare MLPCore<DynamicStorage>.
- Docs: vcv-module.md delta #5 marked CLOSED (2026-07-18); MAP.md vcv/ updated.
Closes vcv-module.md delta #5.
Schema-backed modes in console/model.ts are now DERIVED from the codegen
schemas in src/modes/generated/ (source of truth): real param names/groups/
count, plus each mode's ml net shape (MFMode.ml) and schema engine_id. A thin
manifold OVERLAY supplies only label/glyph/ModeClass/input/ordering. New
browser-viable modes xiasri + slp_workshop get derived entries; schema-less
visualizer + c15 stay hand-written on DEFAULT_MODE_ML. Schema min/max/default/
label/curve surface as engine-unit metadata (schemaMin/... on MFParam) without
touching the 0..1 routing semantics.
Switching instrument mode reshapes the runtime-shaped WASM net to the mode's
schema ml config (ConsoleApp effect keyed on [engine, modeId]; no confirm
modal). Boot lands paf_synth dims (4->[10,10,14]->33) once WASM is ready. The
P2.3 axis-count reshape offer still reads the engine's live inputSize and does
not spuriously prompt on a mode switch.
Adds schema-modes.spec.ts (P5 gate): drives switches via a new window.__mf
debug seam and asserts describe() dims, getWeights count, output length/bounds,
and UI param count FROM the imported schemas; spot-checks trainAsync after a
switch. Updates reshape/probe-api/geo-dislike specs to assert from the boot
mode schema instead of the retired fixed 32/126 shape.
All gates green: typecheck, unit (9), build, e2e (33).
- generate.ts re-activates the TS emitters against manifold (types.ts,
per-mode <id>_schema.ts, index.ts); 9 schemas emitted
- firmware-fit check: exactly 3 hidden layers (fixed 4-layer topology) and
every dim within (0, 4096] (the browser kMaxDim)
- golden test restores the TS case against the manifold path (byte-
identical to the retained P1-era snapshot)
One-core-engine P4.3/P4.4: the input/output pipeline processing and the curve
catalog now live in the C++/WASM core (nisps/pipeline/*, nisps/core/math.hpp).
The TS ports are deleted and the browser drives the WASM chains.
Engine:
- WasmIML owns a nisps_pipeline_create handle + bridge buffers and exposes
setInputConfig (TS InputConfig → 15-float wire), processInput, resetInput,
setOutputConfig (Infinity slew → 0), setOutputFreezeMask, processOutput
(in place), resetOutput, curveApply, curveApplyBatch (chunked). Handle +
buffers created in init_, freed in dispose, output-sized buffers realloc'd
on reshape.
- Spine routes setInputs through iml.processInput/processOutput (state lives
C++-side); config source-of-truth stays TS-side and is pushed on attach /
setInputConfig / setOutputConfig. Preserves ?debug=1 fixed-dt determinism
(same dt fed to the WASM calls). EngineApi gains setInputConfig/
setOutputConfig/curveApply/curveApplyBatch.
- New types-only modules: pipeline-types.ts (InputConfig/OutputConfig +
defaults + wire int mappers) and curve-catalog.ts (CurveName + name→id).
types.ts declares the pipeline/curve C ABI. engine barrel updated.
- DELETED src/engine/{input-pipeline,output-pipeline,curves}.ts.
Tests (P4.4 gate — recorded-gesture regression):
- pipeline-golden.test.ts now loads the built WASM (indirect-eval shim,
tests/wasm-load.ts) and drives the frozen gesture/output fixtures through the
C++ chains, honouring the per-event dt clock contract. Tolerance 1e-5
(non-momentum drift <5e-7). The 3 momentum configs carry 1e-2: proven-inherent
f32 drift (a byte-faithful f32 port of the exact original algorithm matches
the WASM to <6e-8 while both diverge from the f64 capture by ~7-9e-3), NOT a
core bug.
- curves-golden.json: linear/square/sqrt/centered_power kept as the original
f64 captures (C++ matches within <3e-8); exp/log/sigmoid/cubic RE-BASELINED
from the WASM (deliberate switch to firmware-exact k=1 exp/log, slope-6
sigmoid, true cubic x^3). Provenance recorded in-file.
- _generate.ts rebuilt as the WASM curve re-baseline tool; pipeline-golden-lib
trimmed to pure data builders.
Docs: fixtures/README.md + manifold/ONBOARDING.md updated.
Gates: typecheck, bun test (9), vite build, playwright e2e (27) all green.
TS half of P3.1/P3.2/P3.3: wire the new WASM exports and delete the TS
approximations now that geometric-dislike, jolt, OU, and the seeded RNG live
in the C++/WASM core.
- types.ts/wasm-iml.ts: bind + wrap dislike_geometric, store_positive,
positive/negative_count, set_avoid_style, jolt_press/step/release/active/
lr_scale/tick_lr_ramp, explore_intensity/get/apply. Weight-mutating wrappers
republish weights (version bump); explore_apply reuses feedbackBuf.
- engine-api: extend .feedback (dislikeGeometric/storePositive/counts/
setAvoidStyle) + new .explore facade. thumbsDown now passes the HEARD
(routed) vector, not the raw MLP output (raw == net output => inert cold-start).
- feedback/controller.ts: delete dislikes[] + applyDislikeBias + both C++ GAP
blocks + the SeededRng field; dislike() -> core dislikeGeometric (returns
action, 15 => cold-start prompt); like() feeds the centroid via the core
thumbsUp; getState() exposes positive/negative counts. Delete feedback/rng.ts.
- engine/exploration.ts: execute the P3 SWAP POINT -> drive engine.explore.*;
delete engine/jolt.ts + ou-explore.ts. UI surface unchanged.
- ConsoleApp: one-time cold-start banner (British spelling), routed heard vector
at the dislike call site.
- App.tsx/spine.ts: under ?debug=1 pin a fixed seed + fixed per-tick dt so the
probe/e2e are deterministic (production keeps time-seeded, real-time dt).
- tests: new geo-dislike.spec.ts; probe gains dislikeGeometric/storePositive/
feedbackCounts/setAvoidStyle; the thumbsDown probe test now drives a real
distinct-heard-vector dislike (bare thumbsDown on the net's own output is
correctly inert under the geometric core). 27 e2e + 9 unit green.
Docs: manifold/ONBOARDING.md engine+feedback sections synced.
- 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.
