feat(manifold)!: P1 — retire playground/, manifold is the sole browser app

Playground archived at branch archive/playground-solidjs (tag
playground-solidjs-final) and deleted from main. Retargets:

- run-all-tests.sh stage 5 → manifold (typecheck + bun test + build +
  playwright via non-snap node runner, BUILD-PLAN gotcha)
- ci.yml playground-tests → manifold-tests; osc-bridge.yml → manifold/osc-bridge
  (was already broken: playground/osc-bridge no longer existed)
- codegen: TS emission target removed (returns at P5 → manifold); golden
  test now C++-only; TS emitters retained dormant
- .gitignore: manifold/osc-bridge paths; drop dead playground faust exception
- docs: AGENTS.md gates, README quickstart, MAP.md, ALIGNMENT.md (C15 now
  archive-only — defect #1 updated), AGENT-REFERENCE.md, specs/MAIN.md

Since 2026-07-13 (P1 of `docs/specs/plans/one-core-engine-refactor.md`) the sole browser app is the React Manifold; the SolidJS playground is archived (`archive/playground-solidjs`).

+**What.** C15 never got past a stubbed placeholder mode, and with the playground retired at P1 (2026-07-13) it has NO home on main — the stub UI, `c15.wasm`, and `c15-glue.js` live only on branch `archive/playground-solidjs`. Mic input for XIASRI / SoundAnalysisMIDI is likewise not wired in manifold.
 
-**Why it blocks the mission.** "Browser engines ⊇ firmware engines" was a non-negotiable. Without C15 + mic input, the playground can't fully demonstrate the modes; users can't audition XIASRI or SoundAnalysisMIDI in the browser.

 ### Q3: Engine event taxonomy (2026-04-29)
 
 `nisps/modes/base.hpp` exposes a `ControlEvent` ring buffer pop_events interface for sequencer modes (BreakOr, Elysiamorf). Currently events are a flat enum. As we add more event-emitting modes (custom MIDI mappings, lighting, networked control), how should the event vocabulary grow? Open question; revisit when we add the third event-emitting mode.

 The original a-immersive was mobile-first ("designed for touch / foldable phone use"). The SolidJS rewrite is desktop-first by default. If the research story is "the user holds a phone and pinches to zoom while a synth runs in their pocket", we'll need a responsive pass. Defer until we have user data.

 ## Conventions
 
 - Firmware mode selection is compile-time only — `#define MEMLNAUT_MODE_TYPE` in the `.ino`.
 - `nisps/` follows Chris's RP2350 perf rules globally: no heap, `static const float` for non-trivial constants, strict `.f` suffix, memory section attrs (`NISPS_AUDIO_MEM`, `NISPS_AUDIO_FUNC`, `NISPS_APP_SRAM`, `NISPS_HOT`, `NISPS_FORCE_INLINE`).
 - C++ identifiers: `PascalCase` types, `snake_case` functions/variables, `kPascalCase` constexpr. JSON keys `snake_case`. TS types `PascalCase`, components `PascalCase.tsx`, modules `kebab-case.ts`.
-- `Curve` enum lives in `nisps/core/math.hpp` (lowercase: `linear/exp/log/square/sqrt/sigmoid/cubic`); generated mode headers re-export via `using Curve = ::nisps::Curve;`. TS mirror at `playground/src/output/curves.ts` with same names.

 - WASM and firmware share the same C++; WASM is fixed at `MLP<32, 10, 14, 18, 126>` (`nisps_ml_create` ignores requested dims — see `plans/one-core-engine-refactor.md` P2) and modes use a slice of outputs based on schema's `output_size`.
 - Cross-platform parity: `scripts/parity-check.sh` enforces native vs WASM agreement within 1e-5.

-### Stores + reactivity
+Read `manifold/ONBOARDING.md` before touching manifold UI — layering, Stages, Dock, gotchas.
-
-All stores use SolidJS `createStore` for objects, `createSignal` for primitives. ML outputs are stored in a separate Float32Array signal (per the migration plan's perf guidance). Persistence (debounced 200ms localStorage round-trip) wired in `playground/src/stores/persistence.ts`. The signal bus (`bus.ts`) handles cross-store events (`ml.*`, `mode.*`, `pin.*`, `ui.*`).
-
-### Control surface
-
-Three compound axes (Boldness / Memory / Precision) interpolate per-axis tables to drive ~6 underlying parameters each, with offset overrides ("trim-pot" model). State is in `control-store`. Six built-in control presets (Default, First Touch, Jazz Hands, Sculptor, Improviser, Microscope) available via the ModeShell control bar.
-
-### Debug probe (Playwright)
-
-`window.__nisps` is exposed synchronously and bypasses Solid reactivity (uses `untrack`/`batch`). API matches the `.local/recon/04-playground.md` spec — `setInputs`, `getOutputs`, `getLoss`, `train`, `thumbsUp`/`thumbsDown`, `randomise`, `clearExamples`, `inferBatch`, `getLayerStats`, `saveState`, etc.

+- Mic input through the worklet for XIASRI / SoundAnalysisMIDI is not wired in manifold.

-- The browser Jolt/OU controls (`playground/src/ml/jolt.ts`, `playground/src/output/ou-explore.ts`) reimplement the gesture math in TS rather than calling the C++ `ml::Jolt`/`ml::OUNoise` through WASM. They drive weights via the existing `nisps_ml_get/set_weights` bindings and use `Math.random()` (not the deterministic `Rng`) — fine for stochastic exploration aids, but firmware↔browser bit-parity of the noise itself is intentionally not guaranteed.

-2. **AudioWorklet thread**, via `nisps-processor.ts`. Used for engine
-   processing (per-128-sample-block).
-
-Why not share?
-
-- AudioWorklet runs on its own thread. Sharing memory across threads
-  requires SharedArrayBuffer + locking on every heap access; far more
-  expensive than two heaps.
-- AudioWorklet has neither `fetch` nor ESM `import`, so it can't load
-  the Emscripten glue (`nisps.js`). The main thread fetches the WASM
-  bytes once and posts them here as a transferable `ArrayBuffer`; the
-  worklet then `WebAssembly.instantiate`s directly.
-- Engines and ML never interact in the audio path. The main thread
-  computes the parameter vector each frame and pushes it into the
-  worklet via `port.postMessage`. The worklet pushes nothing back per
-  block (analysis features, if needed, are batched and sent at low
-  rate).
-
-Per-frame data flow:
-
-```
-Joystick → input pipeline → mlStore.outputs (Float32Array, length=126)
-                                           ↓ EngineHost.setParams()
-                                           ↓ port.postMessage (transferable)
-       AudioWorklet ← WASM engine.process_block ← WASM engine.set_params
-```
-
-## Custom WASM loader
-
-We do **not** use the Emscripten JS glue inside the worklet — the glue
-contains `URL`, `Worker`, and `fetch` references that don't exist in
-AudioWorkletGlobalScope. Instead `nisps-processor.ts` calls
-`WebAssembly.instantiate` directly with hand-rolled imports and
-discovers exports by walking the export descriptors. This makes the
-worklet bundle small (just the processor TS) and avoids touching the
-Emscripten init path.
-
-The trade-off: only the engine API is callable here, not the ML API.
-If you ever need ML inference inside the worklet (we don't), use the
-main thread copy and post params over.
-
-## Block size
-
-AudioWorklet always calls `process()` with 128-sample blocks. Our
-heap buffers in `nisps-processor.ts` are sized to match. Don't change
-the block size without changing the buffer allocations.

-/**
- * WasmIML — main-thread ML interface backed by `nisps.wasm`.
- *
- * Owns:
- *   - One `nisps.wasm` instance.
- *   - One MLP handle.
- *   - A JS-side `Dataset` (mirrors the C++ ring buffer; see dataset.ts).
- *   - Pre-allocated heap buffers for inputs/outputs/weights/etc.
- *   - A lazy `WasmTrainer` worker for off-thread async training.
- *
- * Threading model (architecture.md §6.4):
- *   - Inference + sync training run on this main-thread instance.
- *   - `trainAsync()` spawns/uses a worker which holds a SECOND wasm
- *     instance; weights round-trip through `getWeights()`/`setWeights()`.
- *
- * Side effects: every mutation that should be visible to the UI calls into
- * `mlStore`. The store is the single source of truth for Solid components.
- *
- * Concept compatibility: this class re-implements the legacy WasmIML
- * surface area documented in `recon/04-playground.md §6` so the existing
- * Playwright debug-probe tests can keep passing once the new probe is
- * wired up.

-/**
- * Disposable Web Worker that runs SGD off the main thread.
- *
- * The worker holds its own `nisps.wasm` instance (architecture.md §6.4).
- * The main thread sends:
- *   - current weights (so the worker is in the same state as the UI),
- *   - dataset (features + labels),
- *   - SGD hyperparameters,
- * and receives updated weights + final loss.
- *
- * This module exposes:
- *   - `createTrainer()`   - factory that spawns the worker, loads its WASM,
- *                           and returns a `WasmTrainer` handle.
- *   - The worker entry-point itself (when this file runs in a Worker).
- *
- * The worker is implemented inline so a single TS file becomes both the
- * main-thread API and the worker bundle. Vite's `new Worker(new URL(...,
- * import.meta.url))` pattern packs it correctly.
- *
- * Lifecycle: each `WasmTrainer` is disposable via `.dispose()` which
- * terminates the worker. Tests should always dispose to avoid leaks.
