Builds the SolidJS-side feature parity with the legacy a-immersive
playground. Every Phase 1–4 feature called out in
.local/recon/04-playground.md now flows through the runtime → stores →
primitives pipeline.
Phase 1 (compound axes / zoom / drawer / trail):
- control-routing.ts: resolves Boldness/Memory/Precision into
input/output/exploration store writes via createEffect.
- SettingsDrawer (new): tabbed sections for Input / Training /
Exploration / Output / Per-param overrides / Advanced. Per-param
ParamEditor list wires through modeStore.setOverride.
- JoyMap navigator added to ModeShell; tap-to-return + long-press
region pin handlers wired into the runtime.
- Anchor mode toggle (auto/sticky/center) exposed via drawer.
Phase 2 (pinning / history / A/B):
- features/snapshots.ts: bridge sessionStore push/pop to actual
Float32Array weights. Auto-snapshot before train/randomize/thumbs-down.
- Undo button + long-press snapshot list popup wired in ModeShell.
- A/B capture/toggle/accept/revert in SettingsDrawer.
- features/overrides.ts buildPinMask() composes override `pinned`
flags + sessionStore param pins; passed to mlStore.moveWeights.
- Region pinning long-press → addRegionPin + auto-snapshot tag
"pinned baseline".
Phase 3 (refinement / exploration):
- features/heatmap-sampler.ts: 16x16 grid via mlStore.inferBatch,
three colour modes, throttled 5/sec, refreshed on ml.trained /
ml.delta_update bus events.
- exploration-store.ts (new): RL noise level, floor/cap/growth/decay,
spread, learning rate, weight decay, auto-explore, pressure.
- Auto-explore timer in mode-runtime drives moveWeights at user
interval, zoom-scaled intensity.
- Pressure feedback: window pointerdown/up timestamps mapped to
explorationStore.setPressure; feeds growNoise/decayNoise.
Phase 4 (output / persistence / polish):
- features/weight-health.ts: histogram, status, per-layer L2 deltas,
vanishing/exploding/converged classification.
- features/session-preset.ts: full state capture/restore +
base64url URL sharing; main.tsx applies on load.
- SettingsDrawer Advanced tab renders WeightHealth, GradientFlow,
LayerStats, Heatmap, session preset save/load/share.
Override application:
- features/overrides.ts applies per-param mute/freeze/curve/range
between MLP outputs and the engine. Mode runtime exposes
`paramOutputs` (length = schema.params) which all modes now bind to
OutputDisplay so ranges and mutes are visible.
- Freeze flags push into outputStore.freezeMask reactively.
Mic input:
- features/mic-input.ts: getUserMedia + AnalyserNode-derived
{energy, brightness, pitch, aperiodicity}. Mode runtime feeds
them into channels 2..(input_size-1) when active. ModeShell shows
a Mic toggle for audio_in modes.
Debug probe (probe.ts):
- Synchronous bypass for snapshot, A/B, pins, overrides, axes,
spread, output freeze, heatmap, weight health, session presets,
URL params, bus emit/on. Untracked reads/writes throughout to
avoid SolidJS reactivity surprises in tests.
Modes:
- All 8 firmware mode TSX files now use the default SettingsDrawer
(no per-mode SliderBank scaffolding). They bind OutputDisplay to
runtime.paramOutputs (post-override) instead of processedOutputs.
Build status:
- bun run typecheck: clean
- bun run build: clean
- dev server smoke: index, /modes, mode-runtime, SettingsDrawer,
features/* all serve.
Note: bd close meml-5wg failed because Dolt server unreachable from
this worktree. Issue should be closed manually by orchestrator.
