+# SPRINT 2 prompts (assembly — fire A/B/C/E together, D at gate 1)
+
+Same rules: own clone (`~/Documents/shades-lane<X>` on m3ultra), branch `lane/<x>`,
+rebase onto latest main FIRST (it moved: all lanes merged + importmap + path
+fixes + M3 clip pack). Read THREADS.md from the [I] integrator entries down,
+then SPRINT2.md in full — the six decisions at the top are final, stop
+re-deciding them.
+
+## Lane A — Sprint 2
+
+> You are Lane A on SHADES 3D, Sprint 2. Rebase onto main, read THREADS.md's
+> [I] entries and SPRINT2.md §Lane A. Your sprint IS the assembly: in main.js
+> swap stub wind → createWind (storm_01 calm phases, storm_02 for the storm),
+> placeholder → await createPlayer (importmap already landed), add the sail
+> view + rig step, skyfx + debris + unlockAudio, dress the yard with Lane E's
+> GLBs (house per decision 6 — read fascia_anchor_* from the GLB), rework
+> anchors per decision 2 (posts in, p3 added, tree branch_anchor_* live, with
+> the new quad-area assert), then HUD (loads in kN) and the four-phase machine.
+> Post "gate 1" in THREADS.md the moment weather+player+sail are live in the
+> yard so Lane D starts. Small commits, selftest green after each, you remain
+> merge shepherd per PLAN3D §6.
+
+## Lane B — Sprint 2
+
+> You are Lane B on SHADES 3D, Sprint 2. Rebase onto main, read THREADS.md [I]
+> entries and SPRINT2.md §Lane B + decisions 3/4/5. Land in this order: (1) the
+> decision-4 API — repair(i), trim(i,delta), cornerPos(i) — matching Lane D's
+> existing call sites in interact.js, with contract entries + asserts; (2)
+> decision 5 — consume debris.pieces in sail.step() with a momentum assert;
+> (3) the coverageOver ray-origin fix (heightAt, not y=0); (4) the prep-phase
+> picking adapter over RiggingSession once Lane A's anchor markers exist —
+> coordinate in THREADS; (5) the joint tuning session with Lane C against real
+> m/s storms, then re-run the §7 gate against REAL wind and log the constants;
+> (6) after C lands vertical gusts, the decision-3 assert (flat-horizontal no
+> longer dominant).
+
+## Lane C — Sprint 2
+
+> You are Lane C on SHADES 3D, Sprint 2. Rebase onto main, read THREADS.md [I]
+> entries and SPRINT2.md §Lane C + decision 3. Land: (1) vertical gust
+> component in storm JSON (downdraft fraction, ~0.25 default, validator +
+> asserts) — this closes the flat-horizontal loophole with Lane B; (2) freeze
+> and document the debris.pieces shape in contracts.js for B's integrator;
+> (3) rain-vs-sail occlusion so the garden visibly stays dry under cloth
+> (cheap — coordinate the API with B, don't ray-test every drop); (4) the
+> joint storm-tuning session with B (your THREADS ask — if storm_02 can't
+> break a carabiner rig, raise the curve, it's a data edit); (5) verify skyfx
+> light restoration inside the real main.js phase transitions once Lane A
+> wires it.
+
+## Lane D — Sprint 2 (start at gate 1)
+
+> You are Lane D on SHADES 3D, Sprint 2. Rebase onto main FIRST — the M3 clip
+> pack landed: player_anims.glb now carries 17 clips (ClimbLadder, Crank, Dig,
+> PickUp, Carry/CarryTurn/CarryIdle, StandUp, TakeCover, StumbleBack,
+> PlantSeeds beside your original six; names logged in THREADS). Also note the
+> integrator fixed /world/ → ./ relative paths in player.js and dev_player.html.
+> Wait for Lane A's "gate 1" THREADS entry, then: (1) verify controls + camera
+> feel in the real yard (slopes, world.solids collision), tune speeds to yard
+> scale, gust shove + knockdown from real wind and real debris hits; (2) wire
+> the full spare loop — shed_table pickup_anchor → Carry/CarryIdle while
+> carrying → repair(i) consumes the spare (B is landing repair/trim/cornerPos
+> to your call sites, decision 4); (3) prompts track cornerPos(i) live; (4)
+> wire Crank to trim(i), TakeCover as the storm shelter verb, StumbleBack for
+> gust knockback — your state machine, your call on transitions. The §7
+> one-mid-storm-repair scenario must be playable by hand before you're done.
+
+## Lane E — Sprint 2 (small)
+
+> You are Lane E on SHADES 3D, Sprint 2. Rebase onto main, read SPRINT2.md
+> §Lane E. Small sprint: (1) canopy sway handles — verify your canopy_* nodes
+> sway cleanly when Lane A drives them, add sway_hint props if per-tree tuning
+> is needed; (2) a 512² sail cloth weave atlas + tear decal strip so the
+> membrane reads as fabric; (3) storm dressing set: wheelie bin (mass_hint),
+> washing line, garden gnome — same one-script determinism + contact-sheet
+> acceptance; (4) when Lane A's yard is dressed, render a contact sheet of the
+> assembled yard from the game camera for DESIGN.md.
