# Lane launch prompts (Opus 4.8, run on the M1 Ultra)

Per lane: clone `git@gitea.partly.party:monster/shades.git` to
`~/Documents/shades-lane<X>`, branch `lane/<x>`, paste the prompt.
Lane A starts first; B/C/D/E can start immediately after in parallel
(they develop against contracts + selftest mocks until A's M0 merges).

---

## Lane A — world, shell & integration

> You are Lane A on SHADES 3D. Read PLAN3D.md fully (you own §5 Lane A), then
> DESIGN.md, then play prototype/ (`python3 -m http.server 8642 --directory
> prototype`). Build the M0 skeleton exactly per PLAN3D §3/§4/§5-A: vendored
> three.js copied from ~/Documents/90sDJsim/web/world/vendor/, stdlib server.py
> on 8801, contracts.js, graybox 30×20 m yard with house edge/trees/posts/garden
> bed, third-person camera, sun lighting, selftest.html harness. Merge M0 to
> main as fast as possible — every other lane rebases on you. Then build the HUD
> against mock data, and act as merge shepherd per PLAN3D §6. Log every landing
> in THREADS.md.

## Lane B — sail simulation & rigging

> You are Lane B on SHADES 3D. Read PLAN3D.md fully (you own sail.js +
> rigging.js, §5 Lane B), DESIGN.md §geometry/§hardware, and prototype/game.js —
> your job is the faithful 3D port of its cloth/load/failure behavior. Build the
> 3D verlet cloth with per-FACE wind pressure (F ∝ area·dot(wind,normal)²) so
> hypar twist genuinely sheds load — prove it with the selftest assert (twisted
> rig peak load < flat rig peak load in the same storm). Corner load = smoothed
> incident-spring stretch; break after 0.4 s sustained overload; flogging must
> be emergent from the freed node. Then the prep-phase rigging UI with the
> prototype's economy. Until Lane A's M0 merges, develop inside selftest.html
> with a stub wind function; keep every module deterministic (dt,t in — no
> Date.now, no rAF in sim code). Log in THREADS.md.

## Lane C — weather, sky & debris

> You are Lane C on SHADES 3D. Read PLAN3D.md fully (you own weather.js,
> skyfx.js, debris.js, data/storms/, §5 Lane C) and prototype/game.js's gust
> scheduler — port its telegraph/ramp/hold/fade shape. Implement
> wind.sample(pos,t) per contracts.js: base curve + gusts + direction change +
> spatial noise + tree wind-shadow. Storms are data (JSON, PLAN3D §4) — author
> storm_01_gentle and storm_02_wildnight. Then instanced rain following local
> wind, storm sky + lightning flash, WebAudio layers (wind bed, gust whoosh,
> rope creak keyed to max corner load, flog when broken), and hand-rolled
> debris (crates/tubs from models/debris/) with player knockdown + sail impulse.
> No physics engine, no deps. Selftest: telegraph lead ≥1.2 s, wind continuity,
> storm JSON validator. Log in THREADS.md.

## Lane D — player character & interaction

> You are Lane D on SHADES 3D. Read PLAN3D.md fully (you own player.js +
> interact.js, §5 Lane D) and 90sDJsim's DEVMANUAL rigged-characters section
> (~/Documents/90sDJsim/DEVMANUAL.md) — its loading rules are law
> (SkeletonUtils.clone, head-bone height normalize, never blind setScalar).
> Copy a ped from ~/Documents/90sDJsim/web/world/models/peds/ into models/
> (copies rule), merge Walk/Running/Happy Idle clips via ~/Documents/
> character_kit/ pipeline; queue Climbing Ladder / crank / dig on the
> ~/Documents/mixamo-fetch wishlist for M3. Camera-relative WASD + anim state
> machine, wind slow/shove/knockdown per PLAN3D, and hold-E interactions via
> interact.register (re-rig with spare 2.5 s, per-corner turnbuckle trim 1.2 s,
> carry-one-item from shed table). Selftest: state machine table test. Log in
> THREADS.md.

## Lane E — nature & hardware assets (Blender)

> You are Lane E on SHADES 3D. Read PLAN3D.md fully (you own tools/blender/ +
> models/, §5 Lane E). Study the house Blender-scripting idiom in
> ~/Documents/3D-STORE/build_booth_room_v23.py and racks_to_glb.py, then write
> ONE deterministic tools/blender/build_yard_assets.py that generates every
> deliverable in PLAN3D §5-E (gum trees with named canopy/branch_anchor nodes,
> fence set, house_yardside with fascia_anchor empties, shed + table, garden
> bed with 3 damage states, raked sail post, ladder, close-up shackle/
> carabiner/turnbuckle, ref_capsule) and exports meter-scale Y-up GLBs, <15 k
> tris, low-poly stylized to sit beside the 90sDJsim ped fleet. Also copy +
> scale-check the debris set from ~/Documents/3D-STORE/clean_glbs/ into
> models/debris/. Verify every export by rendering a contact sheet against the
> 1.7 m ref capsule (the 3D=models/_thumbnails pattern). Commit script AND
> GLBs. Log in THREADS.md.
