Phase 3 (S1, S5, S6, S25, L11, L37, ST11, ST12). Behaviour-preserving by
construction: the diff on the generated directories is PURELY ADDITIVE (217
insertions, 0 deletions), so no emitted constant changed value. This moves where
truth lives; it does not change what truth says.
- S5: nine mode headers each carried a mechanically identical 12-field
positional ParamSchema aggregate. codegen now emits one
`inline constexpr ParamSchema k<Mode>Schema` per mode, and the struct itself
moved into generated/schema_types.hpp. Each param_schema() is a one-line
return.
- S6 + S25: every mode hand-typed its net shape a second time as MLP template
args, duplicating the schema's own dims. codegen emits a `<Mode>MLP` alias
built from the already-emitted constants (not re-literalled), and all nine
modes use it. NMaxExamples still defaults from kDefaultMaxExamples (Phase 2).
- S1: model.ts hand-imported all nine schemas by name and hand-paired each with
its overlay — so the SET of modes was hand-maintained and could silently drift
from codegen. codegen now emits ALL_MODE_SCHEMAS; SCHEMA_MODE_OVERLAYS is
purely display truth (label/glyph/css/order), which stays hand-curated.
- L37: deleted the hand-written modeEngineId switch, which duplicated
schema.engine_id and silently defaulted unknown modes to 'thru'. Routes on
MFMode.engineId with exactly one documented exception: sound_analysis_midi
declares engine_id 'thru' because its ModeBase audio slot really is
NoOpEngine, while it separately drives the real AnalysisEngine.
- L11: ExternalSynthMIDIMode's shape was literal in two places; now named once
in an ext_synth_defaults namespace with an ExtSynthMIDIMLP alias. Full folding
into the JSON pipeline is NOT done and the reason is recorded in-file: it is a
template family over an externally-supplied Device and variable NOut, with no
single (device, NOut) schema to author.
- ST12: extracted codegen/lib.ts for the helpers both generators duplicated, and
corrected the comment that claimed they had to be separate. Proof the
extraction was behaviour-free: regenerating the MIDI-device outputs produces a
byte-identical tree.
- ST11: deleted codegen/templates/ — dead "reference" files no generator reads,
already drifted from the real emitters.
Gates: run-all-tests.sh ALL GREEN; codegen idempotent (re-running both
generators yields no further diff), which is what CI's dirty-diff gate checks.
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).
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).
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.
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)
