monkey-w1n5t0n 9ad1f78ddd docs: the specs disposition pass (plan §8) 
Roughly 20k lines were deleted from this repo in the last week and much of the
corpus still described the pre-deletion world in the present tense. Executes
the §8 table: archive the retired, reclassify the executed, prune the stale.

  aimmersive-clone-spec      -> _archive/ with a deprecated-by note
  feedback-modes-port-spec   -> plans/, kind: plan, status: executed
  manifold-parity-features   -> plans/, kind: plan, status: active
  playground-2.0-rewrite     -> status: superseded
  engine-architecture        434 -> ~120 lines; seam + spine kept, rewritten
                             present-tense against the shipped engine/
  MAIN.md                    six contradicted claims fixed; registry resynced
  vcv-module.md              pruned to the current 8->16 contract and made the
                             single .nisps format spec
  vcv/NISPS-FORMAT.md        DELETED — documented a v1 format that no longer loads
  vcv/README.md, BUILDING.md rewritten to the real contract, menu, OSC table
  inputs/backends/dock trio  grounding sections marked historical, dead cites fixed

Two rows of the §8 table were themselves wrong, corrected here: the deleted
full-state sync lives in backends-spec.md §6.3, not vcv-module.md (which has no
§6.3), and codegen/README.md was already a MAP pointer with no port-solidjs
trigger left to remove.

Beyond the table — found by sweeping every backticked path in the changed docs
against `git ls-files`, which is how these should have been caught before:

  manifold/ONBOARDING.md documented a UI that Phase 1 deleted, as if current:
  SplitStage, ReadoutStrip, InputMini, BackendAdvanced, AltitudeNav, and a
  shot.spec.ts that does not exist. The whole stage table was keyed on a `focus`
  axis that no longer exists — selection is now sandwich > particles >
  composite. This matters more than the rest: CLAUDE.md tells every agent to
  read ONBOARDING.md first for Manifold work, so it was actively teaching a
  fiction. Rewritten against ConsoleApp.tsx.

  MAP.md claimed the input layer reduces axes to the engine arity with an
  "even/odd blend". input-layer.ts says the opposite in its own header: one
  dedicated slot per axis, 1:1, into a 32-input over-provisioned head, and
  mean-blending was removed deliberately because it diluted every source.

  AGENT-REFERENCE.md still promised TS emission "returns at P5" (landed),
  per-mode dims "become schema-real at P5" (landed at P5.3), and pointed at
  nisps::FixedBuffer (deleted).

Doc-right/code-suspect, filed rather than fixed: VCV computes derivedMean/Std/
Delta and cachedNovelty behind a live context-menu toggle that nothing reads;
vcv/plugin.json points at the MusicallyEmbodiedML org rather than this repo's
origin; and the module defaults to UDP 7001+id%64 while bridge.ts defaults to
9000, so out of the box they do not meet.

Firmware-build docs are deliberately untouched — the PlatformIO migration
lands next and rewrites all of them.

Manifold — Build Plan & Locked Decisions (resume anchor)

Dated 2026-06-27. Executed — the Manifold app was built, deployed to /next/, and is the sole browser app; current ground truth is MAP.md §manifold + manifold/ONBOARDING.md (the manual redeploy recipe below is superseded by the CI-gated push-to-main webhook). What survives from here: the VPS non-snap-node Playwright invocation (now in MAP.md Entry points) and the locked naming/copy decisions (never "C15", British spelling).

Locked decisions (operator-confirmed 2026-06-27)

Decision Choice
App directory manifold/ (Vite + React + TS), beside playground/ until parity + sign-off
Engine to wire The parity-tested TS engine (playground/src/ml/wasm-iml.ts + audio/engine-host.ts + worklet), same nisps/ core the firmware builds from
Staging deploy meml.lnfinitemonkeys.org/next (server-scope COOP/COEP already set); live a-immersive stays at /
Default FEEDBACK_MODE Explore & place (Mode 2, positive-only); Geometric-dislike selectable
Default SOLO/arm Mask-gradients / column-freeze (variant a); ZeroLoss + DontCareExample selectable
Modular N×M MLP Multiple WASM modules + warm-start ({2,4} then {2,4,8}); NOT runtime-shaped, NOT padded SUPERSEDED 2026-07-13 by one-core-engine-refactor.md §1: runtime-shaped MLP in browser (warm-start retained), fixed template on hardware
VCV bridge transport WS↔OSC bridge server (reuse existing Deno bridge; bidirectional training)
Synth UI label "Powerful Synth Engine" — the string "C15" must NEVER appear in the UI
Product copy British spelling (randomise, visualise, colour)

Spec docs (now in docs/specs/ and subdirs)

  • docs/adr/rl-feedback-design.md — the learning engine (both modes + solo); §1 = verified ground truth: the feedback C API, MLHandle.feedback, 0xFEEDBACC0DE salt, parity Stage 5, and CMakeLists.txt:59 registration ALL ALREADY EXIST — edit/extend, don't re-scaffold. Mode 1 ports to upstream 0a541cc InterfaceRL.
  • dock-spec.md — six drawers + per-output control row + tri-state semantics + advanced modals.
  • backends-spec.md — OutputBackend adapter interface; VCV module already at vcv/ (2-in/12-out) → evolve to 8→16 + LED rings; faithful visualizer.js particle port (algorithm documented).
  • inputs-spec.md — modular XY/WebMIDI/gamepad; multiple-WASM-module reshape with warm-start.
  • recon/findings-{feedback-behaviour,engine-surface,design-and-manifold}.md — Phase-1 audits.
  • recon/upstream-firmware-survey.md — git topology; latest InterfaceRL = 0a541cc.
  • plans/playground-2.0-rewrite-plan.md, engine-architecture.md, _archive/aimmersive-clone-spec.md, plans/feedback-modes-port-spec.md — the prior planning corpus.

Reactive spine → React (load-bearing, from findings-design-and-manifold.md §4)

Spine lives BELOW React in an external store: setInput action derives processed→ml→routed eagerly+synchronously and fires the single backend.send at its tail (off-render). React subscribes via useSyncExternalStore (version counter, not the array); canvases (Manifold/particles) read in one rAF loop. EngineApi exposed via React Context. Lint rule: skins may not import engine internals; engine may not import React.

Phase-3 build sequence (each step keeps live a-immersive up; gate core touches on parity-check.sh @1e-5)

  1. Pull Manifold JSX mirror — DesignSync (session-bound) → docs/redesign/manifold-export/ (only tokens on disk now; pull components/**, ui_kits/memlnaut/** incl. console/**).
  2. Scaffold manifold/ — Vite + @vitejs/plugin-react + strict TS, COOP/COEP dev+preview headers, base:'./' + base-aware WASM URLs, worklet via ?worker&url, copy public/nisps.{wasm,js}.
  3. Engine adapter — lift WasmIML + EngineHost + worklet + input/output pipelines from playground/src; replace Solid mlStore/coreBus side-effects with an injected emitter; build the framework-neutral EngineApi + the external-store reactive spine + React EngineProvider/useEngine.
  4. Primitives — port the 12 design primitives (Button/Slider/PillToggle/Panel/Badge/Switch/StatusLine/ XYPad/VirtualJoystick/ControlAxis/CurvePlot/Sparkline) from window-global JSX to ES-module React/TS + tokens.
  5. Console convertible shell — ConsoleApp/CompositeStage/SplitStage/OutputStage/InputMini/Manifold/Dock/ Drawers/VerdictCluster/ReadoutStrip/AltitudeNav (+Perform/Zen). Replace MF_infer with real engine. The single draggable divider with width-based representation demotion (full manifold → pad → minimap) is the centre.
  6. Dock real contents (dock-spec) — six drawers, per-output control rows, tri-state, advanced modals.
  7. Modular inputs (inputs-spec) — InputSource adapters (XY/WebMIDI/gamepad), N-channel pipeline, multi-module warm-start rebuild.
  8. Backends (backends-spec) — OutputBackend adapters: Powerful Synth Engine, particle visualiser (faithful port), WebMIDI, OSC (reuse Deno bridge), CV/gate.
  9. Feedback engine (rl-feedback-design) — TS-prototype-first (audible directional-away + interpolate-between- corners are pass/fail oracles via existing WasmIML primitives) → C++ core (ReplayStore + train-toward-targets
    • solo column mask) → C API → TS FFI → dock selector. Every core step gated on parity.
  10. VCV module — evolve vcv/ to 8→16 + LED-ring widget (palette from tokens) + WS↔OSC bridge + bidirectional training.
  11. e2e — window.__nisps synchronous probe + Playwright (spine invariant: setInputs → outputs+params change in one tick; no-per-frame-alloc fuzz).
  12. Deploy /next, MAP.md + ALIGNMENT.md + CLAUDE.md sync, hand operator URL. Archive playground only after parity + sign-off.

Animations (workstream G, parallel to build) — Manim skill at ~/src/hermes-agent/skills/creative/manim-video

Knob 1:1 · XY→2 numbers · dimensionality fan-out (knob/fader/touchpad/2D/3D joystick) · feedback contrast (geometric push-away vs explore-and-place). Plus interactive in-app onboarding demos. Feedback piece reflects the locked default (Explore & place).

Manifold mirror status (docs/redesign/manifold-export/) — updated 2026-06-27

PRESENT on disk: all 6 token CSS + styles.css; 12 primitives (components/{core,control,data}/*.jsx); console kit — ConsoleApp, CompositeStage, SplitStage, OutputStage, InputMini, Manifold, model, shared-ui, Dock, Drawers, OutputEditor, VerdictCluster, ReadoutStrip, CurvePad. STILL TO PULL via DesignSync (non-core; project id 49091559-c3ce-47cb-a14f-08d62c26fe09): console PerformApp.jsx, ZenApp.jsx; ui_kits/memlnaut top-level (App, ModeView, OutputBars, TopBar, TrainingPanel); output-routing/ (Editor, model, parts, variants); support.js; the specimen *.html. These are altitude/alt-routing variants and specimens — not needed for the core convertible Console build (steps 2-9). Pull when building Perform/Zen altitudes or the routing-matrix Full modal.

Key port notes from the mirrored JSX:

  • CompositeStage IS the convertible: single split ratio ∈[0,1], SNAPS [0.14,0.33,0.5,0.66,0.86] w/ magnetism, SHUT=0.1 collapses a side to a draggable corner minimap; tier demotion by measured width (full→pad / field→list).
  • model.jsx MF_infer is the sin/cos placeholder to REPLACE with WasmIML; it still lists a c15 mode labelled "C15" → relabel to "Powerful Synth Engine" (and the synth backend everywhere).
  • Drawers.jsx = the PLACEHOLDER drawers (Shape/Feel/Route/Health/Help) → replace with dock-spec's six real drawers.
  • OutputEditor/OutputStage/ReadoutStrip already implement the off/fixed/live tri-state + per-output min/max/curve
    • alt-click cycle — the baseline the dock-spec per-output control row formalises (add mute + solo/arm).
  • Components use window.* globals + window.ManifoldDesignSystem_490915 — convert to ES-module imports.

Build status — 2026-06-27 (Phase-3 in progress)

DONE + verified (typecheck+build green): scaffold manifold/; engine layer (framework-neutral EngineApi + reactive spine + EngineProvider/useEngine + window._nisps probe; added the missing nisps_ml_feedback* TS bindings — no C change); 12 primitives; convertible Console shell (ConsoleApp/CompositeStage/etc) wired to the real engine (MF_infer replaced; default mode = Explore-and-place; synth = "Powerful Synth Engine", 0 "C15" in bundle). DEPLOYED to https://meml.lnfinitemonkeys.org/next/ (docroot subdir of meml-aimmersive, no nginx change; COOP/COEP inherited; live a-immersive untouched at /). To redeploy: cd manifold && bun run build then rm -rf /home/w1n5t0n/deployments/meml-aimmersive/next && cp -r manifold/dist /home/w1n5t0n/deployments/meml-aimmersive/next && cp .../next/index.html .../next/a-immersive.html (the a-immersive.html copy satisfies nginx index a-immersive.html so /next/ resolves).

CAVEAT — e2e not yet run on the VPS: headless Chromium needs libnspr4/libnss3 which aren't installed and need operator sudo (sudo bunx playwright install-deps chromium, or run e2e on the laptop/CI). The smoke spec is written at manifold/tests/e2e/smoke.spec.ts (asserts: engine WASM loads, spine invariant setInputs→outputs change, feedback runs, console renders, no "C15"). Serving smoke (HTML+COOP/COEP+wasm) passed via curl. Operator should verify the live runtime in a real browser at /next/.

REMAINING Phase-3+: real dock contents (dock-spec) · modular inputs (inputs-spec) · output backends + particle port (backends-spec) · feedback C++ engine (rl-feedback-design, TS-prototype-first) · VCV module · full e2e · animations (G). Then MAP.md/ALIGNMENT.md sync + commit + operator sign-off → archive playground.

Build status update — 2026-06-28

ADDED + verified (typecheck+build green, redeployed to /next): real dock contents (six drawers + OutputControlRow with off/fixed/live + mute + solo/arm + dual-range + curve, unified output-state store, per-backend advanced modals, feedback-mode + solo + audio wired) AND the feedback-engine TS prototype (manifold/src/feedback/: FeedbackController — Explore-and-place scratchpad loop snapshot→randomise/nudge→place-at-chosen-location→ warm-start anchor interpolation, undo ring, geometric-dislike mode, example-level solo respect; SeededRng; mode-aware VerdictCluster + Manifold pick-location state). C++ crystallisation gaps tagged inline --- C++ GAP --- → rl-feedback-design §4 (replay store, k-NN geo-push, train_masked column-freeze). ALIGNMENT.md got the output-state divergence note from the dock agent. STILL REMAINING: backends + particle visualiser port (E), modular MIDI/gamepad inputs (F), VCV module (E), C++ feedback crystallisation (B phase 2, gated on parity), full browser e2e (needs libnspr4 via operator sudo), Manim animations (G), MAP.md sync + commit + sign-off → archive playground.

RUNTIME VERIFIED — 2026-06-28 ✅

The /next deploy is browser-verified: the e2e smoke (manifold/tests/e2e/smoke.spec.ts) PASSES — engine WASM loads, spine invariant holds (setInputs→outputs change), feedback runs, console renders, no "C15", no errors. Two runtime bugs found+fixed in the lifted engine:

  1. assetUrl resolved against location.origin → dropped the /next sub-path. FIXED: resolve against document.baseURI (main thread) + pass the deploy base to the async-train worker via its init message.
  2. nisps.js is Emscripten MODULARIZE glue with NO ES6 exports — import() yields an empty namespace. FIXED: fetch + indirect-eval the glue to install global createNispsModule (works on main thread AND module worker). (The playground's identical import()-based loader has the same latent flaw — worth fixing there too.) E2E INVOCATION on this VPS (bun runs under snap confinement that hides system libs from its Chromium subprocess; run the test RUNNER via non-snap node, browsers under the bun cache path): cd manifold && (bun run preview &) PLAYWRIGHT_BROWSERS_PATH=/home/w1n5t0n/snap/bun-js/87/.cache/ms-playwright node node_modules/.bin/playwright test

Build status update — 2026-06-28 (later)

DEPLOYED + e2e-verified to /next, all green:

  • Dock RESTRUCTURED (operator): top Mode selector (Particle System[default]/MIDI/OSC/Built-in Synth/MEMLNaut Editor) + 5 vertically-centred drawers (Learning/Inputs/Outputs/Settings/Help). Old Synth/Visual drawers folded into per-Mode config in Outputs.
  • Settings drawer: monochrome icons (focused orange / unfocused off-white|white|orange), input-map rect↔circular toggle, corner-radius slider (default 2px, overrides --r-1/--r-2 on :root). Store: manifold/src/settings/.
  • Feedback markers on the 2D map: positive (filled dot) + negative (open red ring) at their input location.
  • Monochrome SVG icon set (manifold/src/console/icons.tsx, currentColor).
  • MEMLNaut Editor mode: Web Serial USB scaffold (manifold/src/serial/, stub).
  • MIDI + OSC backends REAL: manifold/src/backends/ (OutputBackend + BackendManager consuming the spine; WebMIDI out w/ per-output CC#/ch/name/range; OSC-over-WS to the Deno bridge in manifold/osc-bridge/). Outputs panel SPECIALISES per backend (dock/OutputsBackendConfig.tsx) + named presets (backends/presets.ts, per-backend localStorage). Audio gated via engine.audio.setMuted on non-synth modes. Naming: synth shows as "Built-in Synth" (operator's latest wording; still never "C15"). REMAINING: faithful particle-system port (Particle System is default Mode — currently passthrough/no flow field yet), modular MIDI/gamepad INPUTS (F), VCV module (E), C++ feedback crystallisation (B ph2, parity-gated), Manim animations (G), MAP/ALIGNMENT sync + commit + sign-off → archive playground. Nothing committed yet.

VCV module — BUILT 2026-06-28 ✅

vcv/ evolved 2→12 → 8 inputs × 16 outputs, compiles + links against Rack SDK 2.6.4 (installed at ~/.local/share/Rack2/Rack-SDK; cd vcv && RACK_DIR=$HOME/.local/share/Rack2/Rack-SDK make → plugin.so 2.4MB). Per-output LED rings (src/LedRing.hpp, drawLayer+nvgArc, proportional fill + glow), palette.hpp from frontend tokens (16-step orange→cyan ramp). WS↔OSC bridge (src/osc_server.hpp) verbs /nisps/{input,output,feedback,weights,examples,state}, default UDP 7001+id%64, routed through the SAME doThumbsUp/Down/enqueueJob paths as the panel — trainable from BOTH VCV and the browser. Retired nisps-core resolved by vendoring src/iml.hpp (self-contained runtime IML, firmware-aligned semantics but not bit-identical — follow-up). Derived outputs moved behind a context-menu toggle. TODOs: browser-side /nisps/feedback emission; redraw panel SVG art for 8/16 (coords relaid in code); align vendored IML optimiser to nisps/ml bit-exactly. REMAINING overall: faithful particle-system port, modular MIDI/gamepad inputs (F), C++ feedback crystallisation (B ph2), Manim animations (G), MAP/ALIGNMENT sync (done this round) + commit + sign-off.

Explore-and-place CRYSTALLISED to shared C++ core — 2026-06-28 ✅ (parity-verified independently)

nisps/ml/feedback.hpp gained FeedbackMode::ExploreAndPlace + Idle/Exploring/Placing state machine (no-heap, nisps::Rng, .f). Granular methods (enter_explore/exit_explore/reroll/nudge/undo/begin_place/commit_place/ cancel_place) for firmware button-mapping + on_down/on_up browser default policy. Controller owns weights+ scratchpad+undo-ring+frozen placed_out_; caller owns add_example+train. C API + EXPORTED_FUNCTIONS added. VERIFIED (orchestrator re-ran, not agent's word): native ctest 4/4; fresh build-wasm + parity-check.sh = PASS 821 floats within 1e-5 (max 2.4e-7), parity Stage 5d exercises enter→reroll→nudge→undo→place→commit. Fixed bug: set_mode(3) fell back to Avoid. nisps.wasm synced to playground/public + manifold/public (md5-identical). manifold/src/feedback/controller.ts REWIRED to call the shared core (TS scratchpad deleted) — app explore-and-place is now firmware-identical; e2e green; redeployed /next. Firmware glue (peripherals.hpp) wired to the hardware flow (down=enter/exit explore, reroll+nudge buttons, like=begin place, up=commit) — NOT compiled (no arduino-cli); Placing-audition static_output() hook is a flagged follow-up. Mode 1 (geometric dislike) untouched. REMAINING: faithful particle-system port, modular MIDI/gamepad inputs (F), Manim animations (G), firmware build

  • flash verification, browser-side /nisps/feedback VCV bridge emission, commit + sign-off.
