feat(dashboard): nvsim Vite+Lit dashboard with WASM transport + App Store [ADR-092]
End-to-end implementation of the operator dashboard for the nvsim
NV-diamond magnetometer simulator. Vite 5 + TypeScript strict + Lit 3,
~93 KB gzipped JS budget, runs the *real* nvsim Rust crate compiled to
wasm32-unknown-unknown inside a dedicated Web Worker.
Validated end-to-end with `npx agent-browser`:
- WASM module boots, build version + magic 0xC51A_6E70 reported
- Reference witness verifies byte-identical to Proof::EXPECTED_WITNESS_HEX
cc8de9b01b0ff5bd97a6c17848a3f156c174ea7589d0888164a441584ec593b4
- Pipeline runs at ~1.88 kHz on x86_64 dev hardware (4500x over Cortex-A53)
- Zero browser console errors; only Lit dev-mode warning (expected)
## nvsim crate (additive)
- New `wasm` feature flag with wasm-bindgen 0.2 / serde-wasm-bindgen 0.6
- src/wasm.rs: WasmPipeline wrapper + referenceSceneJson +
expectedReferenceWitnessHex + referenceWitness + hexWitness exports
- crate-type = ["cdylib", "rlib"] so native + wasm both build
- rand = { default-features = false } drops getrandom OS-entropy path,
preserving the crate's WASM-ready posture
- Native: 50/50 tests still pass, witness unchanged
## dashboard/ (new package)
- Vite 5 + TypeScript strict, Lit 3 elements, signals-based store
- 12 Lit components mirroring the mockup zones (rail, topbar, sidebar,
scene SVG with draggable sources + NV crystal, inspector tabs
Signal/Frame/Witness, console with REPL + filter tabs, settings
drawer, modals, ⌘K command palette, debug HUD, toast, app-store)
- IndexedDB persistence (theme, density, motion, app activations)
- WasmClient → Web Worker → wasm-pack-built nvsim WASM module
- NvsimClient TS interface — same shape covers future WsClient transport
- MagFrame parser (60-byte LE layout matching nvsim::frame)
## App Store (ADR-092 §14a — added during impl)
- Catalog of all 65 wifi-densepose-wasm-edge modules + nvsim
- 13 categories with event-ID-range labels
- Per-app metadata: id/name/category/crate/summary/events/budget/
status/adr/tags
- Fuzzy search, category + status filters, IndexedDB-backed activation
- ADR-092 §14a documents the registry contract and per-app schema
## Build pipeline
- wasm-pack build crates/nvsim --target web outputs to
dashboard/public/nvsim-pkg/ (60 KB pkg, 162 KB unoptimized .wasm)
- npm run build → 93 KB gzip JS, well under 300 KB budget
- ts.config strict, npx tsc --noEmit clean
- Vite worker correctly loads WASM via dynamic import resolving
against worker origin
## E2E validation
- agent-browser open → 4-zone grid renders correctly in dark theme
- Run button → live B-vector trace, |B| readout updates, FPS counter
- App Store → all 66 apps listed with toggles, fuzzy search filters
to "Ghost hunter" on "ghost" query
- Witness verify → green check, console logs "determinism gate ✓"
- Console errors: zero (only expected Lit dev-mode warning)
