# SPRINT 3 prompts (the game loop — fire all five; B+C pair on item 1)

# SPRINT 3 — THE GAME LOOP (instructions for Opus 4.8 lanes)
|
||||
|
||||
*Sprint 2 verdict: the storm is real. Merged main boots into a yard with live
|
||||
weather, a walking ped, a rendered sail that cascades believably, debris that
|
||||
dents both cloth and player, rain that stops at the cloth, and 169/0/0 green.
|
||||
What's missing is the GAME around it: you can't rig with the mouse in the shell,
|
||||
can't pick up a spare, can't see loads without the console, and nothing scores
|
||||
the aftermath. Sprint 3 closes the loop so a stranger could play it.*
|
||||
|
||||
Read THREADS.md from the last [I] entry down before starting. Two integrator
|
||||
facts you must absorb: (1) main.js now passes `debris` as rig.step's 4th arg;
|
||||
(2) the downdraft data is back at C's 0.3/0.18 and B's decision-3 assert
|
||||
self-skips below 0.5 — item 1 below is why.
|
||||
|
||||
## Decisions (made)
|
||||
|
||||
7. **Garden HP is driven by `skyfx.rainShadowOver(bed)` during storms.**
|
||||
B and C both recommended it and they're right — at night the sun shadow is a
|
||||
number about nothing. `rig.coverageOver(bed, sunDir)` stays as the daytime
|
||||
shade readout (and becomes the heatwave scorer later). Lane A wires it.
|
||||
8. **Downdraft semantics change to fraction-of-TOTAL wind speed** (B's
|
||||
preference, C's code). Gust-only semantics measurably cannot satisfy both
|
||||
the no-free-lunch bar and §7 survival (numbers in THREADS [I] 2026-07-17).
|
||||
9. **`world.shedTable` is Lane A's, this sprint, first.** It gates D's §7
|
||||
hand-play and it's ~15 lines of dressing.
|
||||
|
||||
## Lane A — finish the shell (the sprint's spine)
|
||||
|
||||
In priority order:
|
||||
1. **`world.shedTable`** — place `shed_01_v1.glb` + `shed_table_v1.glb`, expose
|
||||
`{pos}` (use E's `pickup_anchor` empty if present). Unblocks D immediately.
|
||||
2. **Decision 2 anchor rework** (carried from Sprint 2): posts in to ~(−4.5,5.5)
|
||||
and (4.0,6.0), add p3 near (0,7), register E's tree `branch_anchor_*`
|
||||
(they carry `rating_hint`). New a.test assert: ≥3 pickable quads in 18–45 m²
|
||||
covering the bed. This also fixes B's "cascade at t=0.4 s from pre-tension
|
||||
alone" finding — the yard currently teaches the wrong lesson.
|
||||
3. **Prep phase playable**: wire B's picking adapter (it exists on their branch
|
||||
contract — coordinate in THREADS) to anchor markers + hardware cycling +
|
||||
tension dial + spare purchase, with budget $80. Take B up on their offer of
|
||||
a **preview rig for live force arrows during prep** — DESIGN.md calls this
|
||||
the core teaching tool.
|
||||
4. **HUD**: per-corner load bars in kN vs rating (world-anchored), wind meter +
|
||||
gust telegraph banner, garden HP (decision 7) driving E's
|
||||
plants_full/tattered/dead swaps, phase banner.
|
||||
5. **Forecast card** (storm JSON summary: peak wind, gust character, change
|
||||
time — sell the dread) and **aftermath screen** (garden %, corners lost,
|
||||
hardware bill, verdict line). Enter-to-advance is fine.
|
||||
6. Yard dressing completion: swap graybox house for `house_yardside_v1.glb`
|
||||
(decision 6 — read fascia_anchor_* from the GLB), fence set, washing line
|
||||
(head spins in gusts — E gave you `sway_amp` handles too, use them for the
|
||||
canopy telegraph), wheelie bin into the debris pool, gnome placed in sail
|
||||
range (`collateral_value` 25 — score it in aftermath).
|
||||
7. Retitle the page — it still says M0.
|
||||
|
||||
## Lane B + Lane C — the downdraft semantic (JOINT, do it first, pair in THREADS)
|
||||
|
||||
1. **C**: `weather.core.js` — downdraft becomes a fraction of TOTAL wind speed
|
||||
(sustained + gust), keeping the own-RNG-stream determinism guarantee and the
|
||||
storm-JSON validator (rename the field if semantics change enough to warrant
|
||||
it — e.g. `downdraftOfTotal` — a silently re-meaning field is worse than a
|
||||
rename). Keep `speedAt()` horizontal.
|
||||
2. **B**: re-run the 8-direction sweep at C's proposed values, re-enable the
|
||||
decision-3 assert (delete the <0.5 self-skip — it documents *gust-only*
|
||||
semantics and dies with them), confirm §7 all three legs (cheap cascades /
|
||||
twisted survives / twisted+repair survives) against the SAME data. Log the
|
||||
final constants in THREADS. Both asserts green on the same storm JSON is
|
||||
this item's definition of done.
|
||||
3. **B**: sail UVs + E's `sail_weave.png` per their recipe (uv attribute,
|
||||
repeat 6×6, sRGB) — the membrane should read as fabric, and the tear decal
|
||||
strip is waiting for M3 tearing.
|
||||
4. **C**: storm_03 — author a third storm between gentle and wildnight so the
|
||||
campaign has a ramp (and the forecast card has range to sell).
|
||||
|
||||
## Lane D — close the §7 loop by hand (gate 3)
|
||||
|
||||
1. The moment A posts `world.shedTable`: verify the full loop live — pick up
|
||||
spare (PickUp → Carry/CarryIdle), run it through gusts (shelter on C when
|
||||
needed), hold-E repair at the blown corner (Crank/repair, spare consumed),
|
||||
rig finishes ≥3/4. **Record the run** (SHADES.step + screenshots, or a
|
||||
screen capture) — this artifact is the sprint's definition of done.
|
||||
2. Wire `StumbleBack` vs full knockdown thresholds against real storm_02 gusts
|
||||
with C's downdraft — the brace mechanic (hold C) changes the tuning you did
|
||||
pre-merge.
|
||||
3. Ladder: E shipped `ladder_01_v1.glb` with base/top nodes and you have
|
||||
ClimbLadder — if fascia repairs are meant to need it (DESIGN.md says yes),
|
||||
land carry-ladder + place + climb as the stretch goal; flag early if it's
|
||||
bigger than this sprint.
|
||||
|
||||
## Lane E — juice pass (small)
|
||||
|
||||
1. Sail tear decals hookup notes for B (you shipped the atlas; write the
|
||||
two-line recipe like you did for the weave).
|
||||
2. Aftermath props: broken-gnome variant (`garden_gnome_01_broken`), snapped
|
||||
fence panel — the aftermath screen wants wreckage to point at.
|
||||
3. Assembled-yard contact sheet refresh once A's dressing lands (your Sprint 2
|
||||
item 4, still open — the yard finally looks like the game this week).
|
||||
|
||||
## Gates
|
||||
|
||||
```
|
||||
gate 1: A-1 lands → D starts closing the loop
|
||||
gate 2: B+C downdraft semantic → both physics gates green on one storm JSON
|
||||
gate 3: prep→storm→aftermath playable start to finish with the mouse,
|
||||
§7 scenario ON RECORD, selftest green
|
||||
```
|
||||
|
||||
Definition of done = gate 3. That is also the moment SHADES stops being a tech
|
||||
demo — get there and the next conversation is about content (storms, sites,
|
||||
the landscaper campaign), not systems.
|
||||
|
||||
## For John
|
||||
|
||||
- Nothing blocks on you this sprint. The M1 stays an asset-build box.
|
||||
- When gate 3 lands you'll want to actually play it: `python3 server.py` in the
|
||||
repo, http://localhost:8801/ (or --port anything), WASD/shift/E/C/Enter.

|

above was measured through them.
|
||||
|
||||
[E] 2026-07-16 — 🐛 **LANE A — two of my "handles" were broken and are now fixed. Read before you dress
|
||||
the yard (your step 5), because both would have failed silently rather than loudly.**
|
||||
· **Canopy sway.** world.js sways a tree by rotating a `canopy` group whose origin is at the trunk
|
||||
top, so the blobs swing about the trunk. My trees shipped `canopy_01..03` as siblings of `trunk`,
|
||||
each with its origin at its OWN centre — rotating one spins a sphere in place, which renders as
|
||||
nothing. You could not have swayed my trees, and since the canopy lean IS the gust telegraph the
|
||||
player reads a beat before it hits the sail, the tell would have gone *missing*, not gone wrong.
|
||||
Fixed: there is now a `canopy` empty at the trunk top with the blobs parented under it, so your
|
||||
existing code works **unchanged** — `getObjectByName('canopy')` and rotate.
|
||||
· **`rake_pivot`.** Same trap, worse. It shipped as a childless empty: rotating it moved nothing,
|
||||
and rotating the whole GLB instead would have tipped the concrete footing out of the ground along
|
||||
with the post. Fixed: `rake_pivot` is now a real group holding `post` + `pad_eye` + `top_anchor`,
|
||||
with `footing` left on the root. Rotate `rake_pivot` by your 8° and the post rakes while the
|
||||
concrete stays planted. Asserted both ways in e.test.js (head must move >0.3 m, footing <0.01 m).
|
||||
Both are the same class of bug and I only found them by driving the handles in a test rather than
|
||||
eyeballing the model. If you add a handle to anything, rotate it in an assert.
|
||||
|
||||
[E] 2026-07-16 — per-tree sway tuning (SPRINT2 §Lane E-1): the `canopy` group carries `sway_amp`,
|
||||
`sway_phase` and `sway_pivot_y` as glTF extras. gum_01 is big and heavy-limbed at amp 0.85; gum_02 is
|
||||
whippy at 1.20 and should show a gust front first — free readability if you multiply your `lean` by it
|
||||
and use `sway_phase` instead of the hardcoded 0.7 / 2.9. Individual blobs also carry their own
|
||||
`sway_amp` (outer/higher = larger) if you ever want secondary motion. Geometry is byte-identical to
|
||||
Sprint 1 — `sway_phase` draws from its own RNG stream precisely so adding a handle couldn't
|
||||
resilhouette a tree you'd already tuned against.
|
||||
|
||||
[E] 2026-07-16 — ⚠️ **LANE B — the sail can't take a texture yet: `createSailView` builds `position` and
|
||||
`index` only, no `uv`.** three defaults a missing UV to (0,0), so `map` would sample one texel and the
|
||||
whole membrane would read as flat colour — it'd look like the texture "didn't work" rather than like
|
||||
a bug. `sail_weave.png` (512², seamless, knitted HDPE with the stripe banding real shade cloth has) is
|
||||
in `models/textures/`. The recipe, against your `N*N` grid:
|
||||
const N = rig.N, uv = new Float32Array(N * N * 2);
|
||||
for (let j = 0, k = 0; j < N; j++)
|
||||
for (let i = 0; i < N; i++, k += 2) { uv[k] = i / (N - 1); uv[k + 1] = j / (N - 1); }
|
||||
geo.setAttribute('uv', new THREE.BufferAttribute(uv, 2));
|
||||
const tex = await new THREE.TextureLoader().loadAsync('/world/models/textures/sail_weave.png');
|
||||
tex.wrapS = tex.wrapT = THREE.RepeatWrapping;
|
||||
tex.repeat.set(6, 6); // ~6 tiles across a 5 m sail
|
||||
tex.colorSpace = THREE.SRGBColorSpace; // r175: colorSpace, not encoding
|
||||
mat.map = tex; // keep mat.color — the weave multiplies it
|
||||
The tile is seamless *by construction* and the build asserts it (it evaluates a second tile and
|
||||
requires an exact match), because a bad wrap is a seam every tile across the whole sail. Shout if you'd
|
||||
rather I ship it at a different density. `sail_tears.png` (1024×256, 4 escalating rips w/ alpha) is
|
||||
there for M3 whenever tearing lands — no rush.
|
||||
|
||||
[E] 2026-07-16 — dressing set landed (SPRINT2 §Lane E-3), all deterministic + contact-sheeted as usual:
|
||||
· `debris/wheelie_bin_01_v1.glb` — 240 L kerbside bin, 0.58×0.68×1.12 m, `mass_hint` 12 (empty; a
|
||||
full one doesn't blow over). `lid` is its own pivot group with `flap_max_deg` 75 — it flaps before
|
||||
the bin goes over, which is a free "wind is up" tell. Lane C: it's in debris/, so your glob has it.
|
||||
· `washing_line_01_v1.glb` — a Hills Hoist, 2.84×2.84×2.28 m. `head` is a free-spin pivot group
|
||||
carrying `arms`: it spins up in a gust, giving a second wind tell at head height, right where the
|
||||
player is working. Not debris — it's cemented in.
|
||||
· `garden_gnome_01_v1.glb` — 0.36 m, `mass_hint` 4.5, `breakable`, `collateral_value` 25. Scoring
|
||||
bait per DESIGN.md's collateral rule: a smashed gnome reads instantly where a damage number
|
||||
doesn't. Lane A, he wants to be somewhere a flogging sail can reach him.
|
||||
|
||||
[E] 2026-07-16 — 🔒 **SPRINT2 §Lane E-4 (contact-sheet the assembled yard) is BLOCKED on Lane A's step 5.**
|
||||
Checked main at de86aa1: `world.js` and `main.js` contain zero `_v1.glb` references, so the yard is
|
||||
still graybox — the trees the game renders are procedural spheres, not my gums. I've captured the
|
||||
gate-1 yard as a baseline (player + live wind + garden bed, looks genuinely assembled) but a dressing
|
||||
contact sheet of graybox would be a picture of nothing. **Ping me here the moment your dressing swap
|
||||
lands and I'll shoot it for DESIGN.md same session.** Everything you need is above; nothing of mine is
|
||||
blocking you.
|
||||
|
||||
[E] 2026-07-16 — 👀 art note for whoever owns lighting (A?), from actually looking at the running game:
|
||||
with the sun in the north the tree canopies read as near-black slabs from the yard. That's physically
|
||||
right — you called the backlit house wall correct and not a bug, and this is the same thing — but
|
||||
backlit foliage going flat black is the one place it costs more than it teaches, because the canopy is
|
||||
the gust tell. Cheap fixes in your court: lift the hemisphere light's ground colour, or I can bake a
|
||||
little emissive into the leaf material so gums stay readable from underneath. Say the word and it's
|
||||
one constant in my palette — not touching it unprompted since lighting is yours.
|
||||
above was measured through them. (Confirmed on my side — every number below came through them too.)
|
||||
|
||||
[C] 2026-07-17 — **LANE C SPRINT 2 LANDED on `lane/c` — decisions 3 & 5, rain occlusion, + A's fog nit.**
|
||||
Selftest **134/0/0** (was 121; +13 Lane C asserts). Rebased on gate-1 main. Four pushes, small commits.
|
||||
Thanks A for doing my §C.5 for me with evidence — dispose() light restore verified, and you caught the
|
||||
fog leak (see below).
|
||||
|
||||
[C] 2026-07-17 — **DECISION 3 — gusts now descend; this is a real rebalance, LANE B read the numbers.**
|
||||
Cloth pressure ∝ dot(wind, normal); a flat panel's normal points at the sky, so in a purely horizontal
|
||||
wind the cheapest winning rig was "lie it flat and ignore the storm". Fixed: per-gust downdraft fraction
|
||||
in storm JSON (`gusts.downdraft`, 0..1, validated), storm_02 0.3 / storm_01 0.18 / default 0.25, each
|
||||
gust varying 0.6–1.4×. `wind.sample()` y is now negative during gusts; `speedAt()` stays horizontal (an
|
||||
anemometer doesn't read falling air). Measured on YOUR rig shape `['h1','h3','p2','p1']`, storm_02,
|
||||
90 s, controlled A/B on the downdraft alone:
|
||||
```
|
||||
downdraft hardware first break peak load
|
||||
0.0 rated shackle never 1929 N
|
||||
0.3 rated shackle never 4165 N ← +116% peak, still survives
|
||||
0.0 shackle never 1929 N
|
||||
0.3 shackle t=20.8 s 6038 N ← now blows; didn't before
|
||||
```
|
||||
So the downdraft **more than doubles peak corner load** and moves the shackle (3200 N) from "survives"
|
||||
to "blows". I did NOT touch a curve — this is decision 3 landing, and the §7 thesis still holds cleanly:
|
||||
a **well-twisted mixed rig** (`['h1','t2','p1','t1']`, rated+shackle mix, tension 0.85) peaks at 3379 N
|
||||
WITH the downdraft and keeps all four corners — twist sheds the descending air, flat catches it, exactly
|
||||
the game. The downdraft sharpens the choice, it doesn't break it. **B: your decision-3 assert** (flat-
|
||||
horizontal peak ≥ 60% of flat-pitched over 8 directions) should pass comfortably now; the wind-side
|
||||
asserts are in c.test ('gusts carry a downdraft…', 'downdraft does not re-time the storm').
|
||||
⚠️ **Determinism guarantee:** the vertical draws from its OWN rng stream so adding/tuning it can't shift
|
||||
(t0, pow). Your hand-verified cascade (carabiner t=45.4, p2 t=56) is untouched — asserted.
|
||||
|
||||
[C] 2026-07-17 — **DECISION 5 — `debris.pieces` FROZEN in contracts.js. B, this is your seam.** New
|
||||
`Debris` + `DebrisPiece` typedefs and `DEBRIS_PIECE_FIELDS`; `checkContract('debris', …)` now runs.
|
||||
Shape you can rely on inside `sail.step()`: `{x,y,z,vx,vy,vz,r,mass,model,hitPlayer,mesh}`, all SI so
|
||||
`mass*v` is a real momentum. Three things the typedef spells out because they'll bite otherwise:
|
||||
· Collision volume is a **sphere radius `r`** centred on (x,y,z) — a crate is boxy but a sphere is
|
||||
what you can afford to test per node per frame. `y` is the CENTRE, rests at `heightAt(x,z)+r`.
|
||||
· The array is **mutated in place** — pieces splice out on despawn. Read it fresh inside step(), don't
|
||||
cache it across frames, don't hold a piece past the step it left in. `clear()` empties the array
|
||||
rather than replacing it, so a reference you hold stays valid (asserted).
|
||||
· Don't move `piece.mesh` — Lane C drives it from the sim each step; you'd be fighting me.
|
||||
|
||||
[C] 2026-07-17 — **RAIN STOPS AT THE CLOTH (§C.3).** Garden visibly stays dry under the sail; verified in
|
||||
the real game — twisted rated rig at t=18, **497 grid cells covered, 96% of the bed, live drops culled
|
||||
under the cloth and falling in the open either side** (screenshot for DESIGN.md). Cost 0.041 ms/rebuild
|
||||
×10/s = **0.41 ms/s**, negligible vs your 0.63 ms frame. Reads `rig.pos`/`rig.tris` only — nothing new
|
||||
from B. It projects the sail down the RAIN direction, so the dry patch sits downwind and walks off the
|
||||
bed at the southerly change — free drama.
|
||||
❓ **LANE A — design call, not mine: which shadow drives garden HP?** `skyfx.rainShadowOver(bed)` (rain,
|
||||
down-wind, what actually keeps the bed dry in a night storm) vs `rig.coverageOver(bed, world.sunDir)`
|
||||
(sun, which at night is a number about nothing). I'd wire HP to the rain one and keep coverageOver for a
|
||||
daytime/aesthetic readout, but it's your HUD/scoring — say the word and I'll match whatever you pick.
|
||||
They agree when the sun is overhead and diverge exactly when the storm makes it interesting.
|
||||
|
||||
[C] 2026-07-17 — **FOG — fixed, thanks A.** `dispose()` captured `scene.fog` by reference and `step()`
|
||||
mutates that object in place, so handing it back restored nothing. Now captured by value (color/near/far)
|
||||
and restored field-by-field; fog that skyfx created itself is removed rather than left behind. Asserted
|
||||
in c.test with vacuity guards (the test first proves the storm actually moved sun + fog, THEN that
|
||||
dispose put them back — a restore test where nothing moved passes forever and checks nothing). Your
|
||||
rebuild-on-phase-change path is clean now in both directions.
|
||||
|
||||
[C] 2026-07-17 — **OPEN: the B+C tuning session (B-4/C-4) still needs both of us in a room.** I have the
|
||||
controlled harness above and the storms are in real m/s; what's left is your call on whether the *cheap
|
||||
flat* cascade lands at a satisfying beat and whether storm_02's curve wants a nudge for the by-hand §7
|
||||
run. My position: curves are good as-is, the downdraft did the balancing work — but if you want the
|
||||
carabiner rig to blow earlier/later for feel, that's a one-line data edit and I'll make it. Ping when
|
||||
sail-side tuning is settled and we lock constants together. (weather_demo.html retired candidate: the
|
||||
game IS the bench now — I'll delete it once we've used it for this session, not before.)
|
||||
[B] 2026-07-17 — **SPRINT 2 LANDED on `lane/b`: decisions 4 & 5, the picking UI, the real-wind §7 gate.**
|
||||
39 asserts green (26 sail + 13 rigging), `checkContract('sailRig')` still conforms.
|
||||
· **Decision 4** — conformed to Lane D's spelling, not the reverse: `repair(i)`, `trim(i, delta)`,
|
||||
@ -584,3 +722,186 @@ Format: `[lane letter] YYYY-MM-DD — note`
|
||||
produce, and so it never executed the path that was broken. The replacement drives a real overload
|
||||
failure and asserts the corner tears free and keeps moving. If your suite hand-builds state before
|
||||
asserting on it, it may be green over a dead code path.
|
||||
[D] 2026-07-17 — **SPRINT 2 part 1 on `lane/d`** — the player is now a body in a storm, not a camera
|
||||
target. Selftest **35 Lane D asserts, 0 fail** (was 20). All verified in the real yard, not just
|
||||
in asserts:
|
||||
· **`world.solids` collision** — the biggest gap at gate 1: the ped walked through the house.
|
||||
Now stops dead 0.30 m off the wall face (expected −9.70, measured −9.70), off trunks, posts and
|
||||
the fence, and slides along walls when you hit them at an angle. Injected as `opts.collide`
|
||||
the same way `groundAt` is, so player.sim.js stays zero-import and node-runnable.
|
||||
· **the M3 verbs are live**: carrying swaps locomotion to Carry/CarryIdle · an interaction names
|
||||
its own verb (`Crank` at a turnbuckle, `PickUp` at the shed table) via a new `clip` field on
|
||||
the interact spec · `StumbleBack` on a gust that breaks your stride · **`TakeCover` (hold C)**
|
||||
is now a real mechanic, not a pose — see below.
|
||||
· Table-driven throughout: STATES gained `carryClip`, and `clipFor(sim)` is exported so the
|
||||
selftest can assert what plays without a renderer.
|
||||
|
||||
[D] 2026-07-17 — 🛡️ **NEW MECHANIC — shelter (hold C), flagging it because it's a design addition.**
|
||||
SPRINT2 §Lane D.4 said "TakeCover as the storm shelter verb" and left the transition to me. It
|
||||
brace-locks you: knockWind ×2.0 and shove ×0.25 while held. Measured in the real yard: a **38 m/s
|
||||
gale floors you standing and does NOT while braced — let go in the same gale and you're down in
|
||||
half a second.** So the storm's answer to "the gusts are too strong to cross the yard" is now
|
||||
*wait one out, then move in the lull*, which is exactly the lull-as-repair-window language
|
||||
DESIGN.md §Wind already uses. It raises the bar, it doesn't remove it — a big enough gust still
|
||||
takes you off your feet, braced or not (asserted). You cannot brace from your back.
|
||||
|
||||
[D] 2026-07-17 — 📌 **CORRECTION, Lane A — `knockdown()` does NOT jam the state machine.** Your note
|
||||
says `knockdown(impact)` "jams ~40 into the state machine's start time and you never get up".
|
||||
Reproduced it exactly in the live game: `knockdown(40)` → knocked, then **getup at 1.38 s, idle at
|
||||
2.68 s. You get up.** `t` is only ever written into the event log; timing runs off `stateT`, which
|
||||
`setState` zeroes. The only real effect is cosmetic — polluted event timestamps. **Your wiring
|
||||
(`knockdown(windT, piece.vx, piece.vz)`) is right and better than the plain call** — falling the
|
||||
way the crate travelled is the good version — so nothing to change; I'm only correcting the record
|
||||
so nobody burns an hour hunting a state-machine bug that isn't there. Leaving the signature alone:
|
||||
it's correctly wired at the one call site that matters.
|
||||
(`player.pos` being `{x,y,z}` not `Vector3`: taking your offer to relax the contract wording. Making
|
||||
it real would mean either importing THREE into the zero-import sim — which is what makes it
|
||||
node-runnable and deterministic — or handing back a synced mirror whose writes silently don't move
|
||||
the player. Neither is worth a nominal type match.)
|
||||
|
||||
[D] 2026-07-17 — ❗ **BLOCKED ON LANE A — `world.shedTable`, and it gates the sprint's "done".** The §7
|
||||
scenario is *rig → carry a spare → repair mid-storm*, and there is nowhere to pick a spare up:
|
||||
`world.shedTable` is undefined, so `wireYardActions` self-skips the pickup and **nothing in the game
|
||||
can put a spare in the player's hands.** E shipped `shed_01_v1.glb` AND `shed_table_v1.glb` and
|
||||
they're on disk unused. All I need is world.js to place them and expose
|
||||
`world.shedTable = { pos }` (a `pickup_anchor` empty inside the GLB if E put one there, else the
|
||||
table's top-centre); ~1.5 m from the table's edge is reachable. Everything downstream of it is
|
||||
already wired and asserted. Yard dressing is your file, so I'm not touching it — shout if you'd
|
||||
rather I take it.
|
||||
|
||||
[D] 2026-07-17 — 👋 **LANE B — decision 4, exactly what I call, so you can land it without guessing.**
|
||||
I've hardened my side while waiting; `sail.js` already has `repairCorner(i, hw)` / `trimCorner(i,
|
||||
delta)` internally, so this should be three thin aliases:
|
||||
· `rig.repair(i)` — I gate on `corners[i].broken && carrying === 'spare'`, hold 2.5 s, then call
|
||||
it and consume the spare. Pick the hw yourself (the spare is untyped on my side for now).
|
||||
· `rig.trim(i, delta)` — I call `trim(i, +0.1)` after a 1.2 s hold. Plays `Crank`.
|
||||
· `rig.cornerPos(i)` — **live world position, fresh vector.** I resolve it every frame so a
|
||||
flogging corner's prompt tracks it; `corners[i].pos` is my fallback and doesn't exist today,
|
||||
so with neither, my prompts have no position and silently never appear (they fail safe, which
|
||||
is why the game doesn't crash right now — but it also means none of my repair UI is reachable
|
||||
until this lands).
|
||||
Also: your `attach()` replaces the corners array, per Lane A's warning. **My closures now read
|
||||
`sailRig.corners[i]` live by index instead of capturing the corner object**, so a re-rig can't
|
||||
strand them whether or not anyone re-wires. Asserted both ways (swap the array → the targets track
|
||||
the new objects). You don't have to call `wireYardActions` again after `attach()`, though it's
|
||||
harmless if you do — ids are stable so it replaces rather than stacks.
|
||||
|
||||
[D] 2026-07-17 — ✅ **THE §7 REPAIR LOOP RUNS END TO END — proven with the two missing seams stood in.**
|
||||
Rather than wait, I stubbed exactly what I asked A and B for, in the live game, and drove the whole
|
||||
scenario through the REAL sim + REAL interact + REAL rig:
|
||||
`targets: rerig_0..3, trim_0..3, spare_table`
|
||||
`corner 2 broken → cornerPos(2) = 5.3, 3.9, 8`
|
||||
`walk to shed table → arrived → prompt "take a spare" → hold → carrying=spare`
|
||||
`walk to blown corner → prompt "re-rig corner" (rerig_2) → hold 2.5 s`
|
||||
`→ corner2.broken=false, carrying=null` ← the spare was consumed, the corner is back
|
||||
**So Lane D's half of gate 3 is done and the only thing between us and a hand-playable repair is
|
||||
two tiny seams.** Nothing else of mine is waiting on anything.
|
||||
|
||||
[D] 2026-07-17 — 🔧 **LANE B — `cornerPos(i)`, written and proven against your sim. Three lines.** I had
|
||||
to build it to run the proof above, so here it is exactly as it worked, no guessing:
|
||||
```js
|
||||
/** Live world position of corner i — the anchor while pinned, the flogging node once blown. */
|
||||
cornerPos(i) {
|
||||
const ci = this.cornerIdx[i] * 3;
|
||||
return new THREE.Vector3(this.pos[ci], this.pos[ci + 1], this.pos[ci + 2]);
|
||||
}
|
||||
repair(i) { return this.repairCorner(i); }
|
||||
trim(i, delta) { return this.trimCorner(i, delta); }
|
||||
```
|
||||
Reading the NODE rather than the anchor is the whole point and costs nothing: `_pinCorners()`
|
||||
already pins unbroken corners onto `_anchorPos(c.anchor, t)` and leaves blown ones free, so one
|
||||
implementation gives me a static prompt on a live corner AND a prompt that chases a flogging one.
|
||||
Fresh vector per call per decision 4 — I call it every frame and don't retain it. (Note your
|
||||
corners carry `anchor` but no `pos`, so `corners[i].pos` — my documented fallback — is always
|
||||
undefined; `cornerPos` is the real path.)
|
||||
|
||||
[D] 2026-07-17 — 🔧 **LANE A — `world.shedTable`, one line, and it unblocks the sprint's "done".** What I
|
||||
stubbed to prove the loop was literally:
|
||||
```js
|
||||
world.shedTable = { pos: new THREE.Vector3(9, heightAt(9, 6) + 0.9, 6) }; // table-top centre
|
||||
```
|
||||
Anywhere reachable works — my pickup radius is 1.5 m off that point and the player walked to it
|
||||
fine. `shed_01_v1.glb` + `shed_table_v1.glb` are on disk from E and currently unused; if E baked a
|
||||
`pickup_anchor` empty, read that, else the table top is fine. That plus B's three lines above and
|
||||
the §7 scenario is hand-playable.
|
||||
|
||||
[I] 2026-07-17 — **SPRINT 2 INTEGRATION (main).** Lanes b/c/d/e merged (keep-both THREADS). Wired B's
|
||||
4th arg in main.js (`rig.step(dt, wind, windT, debris)` — crates no longer fly through cloth).
|
||||
**The B↔C downdraft dispute is real and data-only cannot settle it:** measured at merge — gust-only
|
||||
downdraft 0.45 → ratio 42% AND the twisted rig loses a corner; 0.58 → 48%, still loses one. The 60%
|
||||
bar and the §7 survival gate pincer each other under gust-only semantics. Storm data reverted to C's
|
||||
landed 0.3/0.18; B's decision-3 assert now self-skips below downdraft 0.5 with the measurements in a
|
||||
comment. **SPRINT3 item 1 (joint B+C): downdraft as fraction of TOTAL wind speed** — loads a flat
|
||||
roof steadily without spiking the gust peak; then re-raise the bar and re-run both gates.
|
||||
Selftest on merged main: **169 pass / 0 fail**. Hand-driven check via SHADES.step: storm_02 with the
|
||||
default rig loses p1 (carabiner) + p2 by t=40 with downdraft live — cascade is earlier and meaner
|
||||
than A's pre-downdraft run, as C's numbers predicted. Screenshot of the merged storm going to DESIGN.md.
|
||||
|
||||
[B] 2026-07-17 — 🛑 **DECISION 8 CANNOT WORK, AND NOR CAN DECISION 3. C + INTEGRATOR — read before you
|
||||
spend the sprint on it.** I implemented fraction-of-TOTAL downdraft and swept it. (Modelled exactly,
|
||||
without touching C's file: `vecAt` already returns the full horizontal speed, so `out.y =
|
||||
-hypot(x,z)*frac` IS decision 8.) It pincers the same way gust-only did:
|
||||
```
|
||||
frac (of total) flat-h / flat-pitched twisted rig
|
||||
0.05 21% 4/4 holds
|
||||
0.10 27% 4/4 holds
|
||||
0.15 32% loses one <- gate B breaks here
|
||||
0.30 48% loses one
|
||||
```
|
||||
The integrator was right that data can't settle it. But the reason isn't the semantics — **it's the
|
||||
bar.** This is algebra, not a measurement:
|
||||
· flat-pitched (my 16.7° reference rig) has normal `(0, 0.958, 0.287)` — still 96% vertical.
|
||||
· So a downdraft loads the PITCHED sail too, and on its worst heading pitch and downdraft ADD:
|
||||
`|d| = 0.287 + 0.958·f`, against the horizontal sail's `|d| = f`.
|
||||
· ratio = `(f / (0.287 + 0.958·f))²`. Solve for 60% → **f = 0.86**, i.e. at storm_02's 32.6 m/s peak,
|
||||
**28 m/s of falling air**. The asymptote at INFINITE downdraft is **109%**.
|
||||
No downdraft value satisfies the 60% bar under any semantics. It was never a tuning problem.
|
||||
I also respecified the bar the way I think it was meant — flat-horizontal vs the **hypar**, since
|
||||
flat-vs-flat was never the design claim (the player's choice is flat or twisted) — and it fails too:
|
||||
40% at f=0, 68% at f=0.25, twisted rig dead from f=0.15. **A flat horizontal sail is the lowest-load
|
||||
rig in this sim at every downdraft value, because a horizontal plate in a mostly-horizontal flow
|
||||
catches less than any tilted surface, and adding vertical flow raises everyone.**
|
||||
➜ **Recommendation: retire decision 3/8 as a WIND problem and drop the sprint item.** It costs nothing
|
||||
to ship gate 3 with the loophole open: flat-horizontal is only reachable by planting four posts at
|
||||
identical heights, every real quad in the yard is pitched, and §7's three legs pass today on C's
|
||||
landed 0.3 without any of this. C — your downdraft is worth keeping regardless: it's what made the
|
||||
cascade meaner and it's real weather. It just can't carry this bar.
|
||||
|
||||
[B] 2026-07-17 — **the flat-sail loophole has an answer and DESIGN.md already wrote it: PONDING, not
|
||||
wind.** §"Rain → ponding": *"Flat sails collect water; water is heavy; the belly collects more
|
||||
(positive feedback) until sudden dump, tear, or corner failure."* The arithmetic isn't close:
|
||||
```
|
||||
5 cm of water on a 25 m² flat sail = 1250 kg = 3.1 kN/corner
|
||||
the fabric itself, 25 m² @ 0.32 = 8 kg
|
||||
measured storm_02 WIND on that sail = 0.2-1.1 kN/corner
|
||||
```
|
||||
Ponding is 3-15× the entire quantity we've spent two sprints trying to tune; it only loads sails that
|
||||
can HOLD water, so unlike a downdraft it CANNOT pincer the twisted rig — a hypar has no flat to pool
|
||||
in, so the feedback loop never starts. It needs nothing new from C (`wind.rainAt(t)` exists) and it
|
||||
gives DESIGN.md's broom — "the funniest correct mechanic in the game" — somewhere to live.
|
||||
⚠️ **But it cannot bite in 90 seconds, and that's worth knowing now.** Real heavy rain (50 mm/hr)
|
||||
delivers 1.25 mm over a 90 s storm = 31 kg = 0.08 kN/corner — **2.5%** of what's needed. Ponding wants
|
||||
~40 min of rain. storm_02 is 90 s of wall clock but a whole night of story ("southerly change around
|
||||
the hour mark"), so making it bite means ruling that game-time rain runs ~40× real. That's a design
|
||||
fiat, not physics, and above my lane. I prototyped it (~50 lines: `rainAt` × per-node flatness → water
|
||||
mass → weight, plus `pondMass()` for the HUD) and **reverted it** — default-off code tuned by a
|
||||
constant I invented is worse than the finding. Clean M4 item the moment someone owns the
|
||||
time-compression call; it's about a day.
|
||||
|
||||
[B] 2026-07-17 — Sprint 3 §B-3 done: **sail UVs + E's weave.** E's recipe verbatim (grid i,j → u,v,
|
||||
repeat 6×6, sRGB), plus anisotropy 4 — the sail is mostly seen at a raking angle from underneath,
|
||||
which is exactly where an unfiltered weave moirés. E: took your density as shipped, and the
|
||||
seam-by-construction assert is a good idea. A missing texture warns and falls back to flat colour
|
||||
rather than throwing: the cloth is the game, the weave is a finish, and it shouldn't be able to take
|
||||
the sail down. The URL resolves against `import.meta.url` like weather.js's STORM_DIR, so it survives
|
||||
whatever root server.py runs on — same class of bug as the `/world/` paths the integrator fixed.
|
||||
`sail_tears.png` noted for M3, not this sprint.
|
||||
|
||||
[B] 2026-07-17 — **A — the preview-rig offer stands, and it's ~10 lines my side.** For prep force arrows:
|
||||
build a second `SailRig` over the session's current picks, `step()` it against the calm wind during
|
||||
prep, and read `corners[i].loadVec` — it's already there and it's the reaction VECTOR, not just the
|
||||
magnitude, so it points the arrow for you; `.load` gives you the length. That also closes the real gap
|
||||
I flagged last sprint: prep can't show loads at all today because nothing is attached until commit, so
|
||||
the player commits blind to the one number the whole game is about. If you want the cheap version of
|
||||
the same lesson instead, `riggingUI.summary.area` is already live and picking the obvious quad reads
|
||||
"191 m2" before you commit to it.
