The Law + +1. **`src/core/` is read-only for all lanes.** It defines the shared types, + block registry, constants, and event bus. If you believe a contract file + has a bug or a missing field, STOP and report it in your summary instead of + editing it — the integrator resolves contract changes. +2. **Own your directory, never write outside it.** Ownership map in §3. +3. **Cross-lane imports: `src/core/` types only.** Never import a concrete + class from another lane's directory. Depend on `IVoxelWorld`, `IMachine`, + `IPlayerView`, `KinematicCollider`, `bus` — not on implementations. In your + standalone demo, mock what you need (§6). +4. **Communicate via the event bus** (`src/core/events.ts`) for anything + fire-and-forget; via the core interfaces for anything synchronous. +5. **No new runtime dependencies.** `three` only. Dev deps: `vite`, + `typescript`, `@types/three`. Textures are painted procedurally on canvas; + audio is synthesized with WebAudio. No binary assets, no CDN loads. +6. **TypeScript strict mode must pass**: `npm run typecheck` clean at handoff. +7. Coordinate system: Three.js right-handed, **Y-up**, 1 voxel = 1 world unit. + Voxel (x,y,z) occupies world space [x,x+1)×[y,y+1)×[z,z+1). World bounds + and all gear placement come from `src/core/constants.ts` (`LAYOUT`) — + never hardcode a magic position. + +## 2.

Key Cross-Lane Behaviors (who does what) + +- **Dirty chunks**: `VoxelWorld.setBlock` (Lane A) marks the containing chunk + (and neighbors when the block borders them) dirty; the engine remeshes dirty + chunks, budgeted per frame. Nobody else touches meshing. +- **Riding platforms**: Lane D machines expose `KinematicCollider`s with + `velocityAt`. Lane B, when the player's ground contact is a kinematic + collider, adds that surface velocity to the player each tick and reports it + via `IPlayerView.groundedOn`. Cylinder colliders rotate about +Y only. +- **Break/place**: Lane D raycasts (voxel DDA for blocks + analytic tests for + machine colliders), calls `world.setBlock`, emits `block:break`/`block:place`. + Lane A reacts by remeshing; Lane E reacts with sound/particles. +- **Quest**: Lane D owns quest state and emits `signal:repair` / `game:win`. + Lane E owns everything audible/visible that reacts to those events. +- **Emissive blocks**: Lane A renders `emissive > 0` blocks with an emissive + material channel. Lane E may pulse a global uniform (via a small exported + hook Lane A provides: `setEmissiveBoost(v: number)` on the renderer) — Lane + A must expose that one function; Lane E must not reach into A's materials. + +## 5. Fixed Timestep + +The game loop runs physics/machines at `FIXED_DT` (1/60) with up to +`MAX_SUBSTEPS` catch-up steps, render decoupled. Every lane's `update(dt)` +must be stable if called with dt = FIXED_DT repeatedly. No lane creates its +own `requestAnimationFrame` loop except inside its own demo. + +## 6. Demo Harness Rules (how you verify alone) + +Each lane ships a standalone Vite page (`demo-.html` at repo root + +`src/demo/Demo.ts`) that runs with **zero code from other lanes**. +Mock the interfaces you consume — e.g. Lane B's demo includes a ~30-line +`MockWorld implements IVoxelWorld` (flat floor + some steps) and one mock +spinning-cylinder `KinematicCollider`; Lane C's demo may include a naive +brute-force mesher (one box per voxel face is fine at demo scale, or +`InstancedMesh`) purely to eyeball the build. Keep mocks inside your demo +file(s), clearly marked `// DEMO MOCK — not for integration`. + +`npm run dev` then open `http://localhost:5173/demo-.html`. + +## 7. Definition of Done (every lane) + +- [ ] `npm run typecheck` passes with your code included +- [ ] Your demo page runs, and its README-style header comment says exactly + what to look at / press to verify each acceptance criterion +- [ ] No writes outside your owned paths; no imports of other lanes' concrete code +- [ ] No console errors in a 2-minute demo session +- [ ] A `HANDOFF.md` in your owned directory: what's done, what's stubbed, + any contract friction you hit, and your public API surface in 10 lines + +## 8. Style + +Match the existing core files: plain TypeScript, no classes-for-the-sake-of-it, +comments only where a constraint isn't obvious from code.

The world is finite, dense, +and hand-authored — a diorama, not a landscape. Every zone is a piece of DJ +gear rendered at monumental scale: the mixer is a mesa of faders and knob +forests, the tonearm is a chrome bridge, an unplugged RCA lead is a rope +bridge into a canyon, and beneath the plinths lie glowing circuit-board caves. + +The palette is deliberately restrained — greys, silvers, matte blacks, dark +rubber — inside a warm birch-plywood shell, with two loud accents: translucent +**blue vinyl** records and emissive **LEDs** (red/green/amber/blue). Think the +inspiration photo: utilitarian gear, warm wood, blue records. + +The fantasy: *the booth is dead when you arrive.* Your job is to bring the mix +back — repair the signal chain, press start, and ride the record while the +whole world lights up in sync with the music. + +## 2. Pillars + +1. **The world IS the gear.** No abstract terrain. Every structure reads as a + real DJ-booth object at 4 mm/voxel scale. +2. **The platters spin and you can ride them.** Rotating kinematic platforms + are the signature mechanic. Everything else is standard voxel play. +3. **Sound is the win state.** Repairs unmute stems of one continuous house + groove; lights and particles react to it. A silent booth is a broken booth. +4. **Zero external assets.** All textures are procedurally painted, all audio + is synthesized. The repo builds from `npm i && npm run dev` alone. + +## 3. Scale & World Map + +1 voxel = 4 mm. Player: 1.8 voxels tall (~7 mm).

Zones (biomes) + +1. **Deck A — "The Blue Record"** (spawn). Steel-grey plinth mesa. On top: the + platter (rotating machine, not voxels) carrying a translucent blue vinyl + disc with a cream label. Strobe dots glow on the platter rim. The pitch + fader is a canyon slot in the plinth; start/stop is a giant press-plate; + the spindle is a climbable chrome pole. The tonearm arcs overhead as a + chrome bridge from its rest to over the record. +2. **The Mixer Massif** (center). Tallest mesa. Face plate at y=67 is a + grid-city: EQ **knob forest** (mushroom-cap knobs on stems), four **fader + alleys** (deep slots with sliding fader sleds), the **crossfader tram** + running left–right at the front, **VU towers** at the back — columns of + LED blocks that light bottom-to-top with the music. Speaker-mesh vents on + the sides are climbable ladders and the way into the mixer's interior. +3. **Cable Canyon** (behind the gear, z 140–200). Tangled RCA and power leads + spanning tabletop to back wall — walkable rope bridges (2×2 cable-block + tubes with red/white/gold RCA plug heads). Dust drifts here; dust-block + boulders to mine. +4. **The Patch Bay** (back wall, y 90–118). The wall-mounted RCA switcher from + the photo, scaled to a cliff-face dungeon: gold jack sockets are round + doorways into shallow rooms; one socket needs its plug pushed home (quest). +5. **PCB Depths** (under-table, y 0–40). Mine down through a plinth vent: + green circuit-board floors, copper-trace paths that glow faintly, solder + blob stalagmites, capacitor pillar rooms, the fuse box (quest), and the + record crate — a plywood cavern of giant vinyl slabs to spelunk between. +6. **Deck B — "The Silent Deck"** (mirror of A, but stopped, dust-covered, its + half-open glass dust cover forming a crystal cave overhead). Comes alive + only at the end. + +## 5. Mechanics + +- **Standard voxel play**: mine breakable blocks (dust, vinyl, knobs, LEDs…), + carry them in a 9-slot hotbar, place them to build bridges/stairs anywhere. + Structural blocks (plywood shell, cables) are unbreakable — the booth keeps + its shape. +- **Riding the record**: platters are kinematic rotating cylinders. Standing + on one adds its surface velocity to you. At "33" (2.0 game-RPM) the label + area is a lazy carousel and the rim is a brisk travelator; at "45" the rim + will fling you — which is a legitimate traversal move (record-edge launch + onto the mixer). +- **The needle plow**: while a deck plays, the stylus tracks slowly inward + along the groove spiral. Its contact shoe is a kinematic pusher — get in + front of it and it shoves you along the groove.
