SPRINT14 gate 3.1. The editor is about to offer these GLBs to an author by
name, which turns every silent field in them into a trap for whoever places
one. Audited the placeable set, fixed the gaps in the factory (nothing
hand-edited), and added the two props D needs to author a yard worth playing.
THE AUDIT, and what it found:
- Four `*_anchor` nodes carried no rating_hint at all — door_anchor,
pickup_anchor, grip_anchor, window_light_anchor. adoptAnchor does
`rating_hint ?? 1`, so silence there does not mean "unrated", it means
RATED PERFECT: a shed door skin outranking a concreted post, conjured out
of a missing field. They now deny it explicitly (`tie_off: false`).
- The carport's price resolved only by coincidence: collateralFor() matches a
STRUCTURE whose site id equals the anchors' collateral string, and site_02
happens to name its structure "carport". The editor will generate
"carport_2" for the second one, and the trap would have gone free — the
gutter bug reborn in the sprint meant to bury it. The GLB now carries
`collateral_key`, like the house does for "gutter". Lane A: the runtime
half is yours (collateralFor could fall back to it).
- The trampoline is unpriced, and now says so rather than omitting it.
Three new rules make the audit permanent, and each is proven able to fail:
no silent anchors, no collateral string nobody prices, no baked anchor_type
outside the checked ANCHOR_TYPE enum. Rule 2 found the carport gap on its
first run — an unfaked negative control.
THE PROPS:
- swing_set_01 (+ wrecked) — the palette's honest middle. It had a ceiling
(gum fork 1.0) and a trap (carport beam 0.22) and nothing in between. Two
apex anchors at 0.45, typed `swing_frame` (NOT `post`: the type string is
what the player reads before committing, and "post" promises concrete),
and a crossbar that is the most anchor-looking object in the game and is
not one. Priced at $140 — proposal, reasoning baked beside it, A rules the
number: gnome 25 < gutter 90 < swing 140 < carport 180.
- tree_jacaranda_01 — a second species whose LADDER is the feature.
Gum: 1.00/0.88/0.76, climb freely, pay 24%.
Jacaranda: 0.95/0.52/0.40, climb at all, pay 58%.
That makes tree choice a real decision instead of "is there a tree".
Unpriced by ruling, same as the bike: no limb-failure event exists to see.
Both wreck/orientation claims are measured in browser coords, not reasoned —
`wreck_falls_toward: "+Z"` is baked AND asserted against the mesh.
Selftest 376/0/0. Two consecutive full factory runs: 44 files byte-identical.
The corner block's seams, all of them A's to close.
ENUM (D's flag). Anchor.type was a closed JSDoc enum 'house'|'tree'|'post',
so site_02 typed its carport 'post' to fit — quietly enrolling it in the
sail-post family that C's venturi and B's audit both read. Widened to E's own
asset strings (carport, carport_post) and, more to the point, CHECKED: it was
documentation for ten sprints, and documentation cannot fail. validateSite now
rejects an unknown type by name. The ladder is untouched either way — D keyed
it on `work`, the mechanism, which is exactly why that was right.
CARPORT (E's proposal, adopted). $180, with E's reasoning intact: gnome 25, a
night's budget 80, so 180 is 2.25 nights — a good week turned broke and felt
for the rest of the run, without ending a strong one outright. Under ~120 it's
a shrug, over ~250 a silent game over that teaches nothing.
The number lives in site JSON, not the GLB: sites are data, and what a carport
COSTS is this site's economy, not a property of the mesh. E's baked value stays
as the fallback and the proposal.
And it BILLS now. E shipped the trap and said it plainly — the anchors said
collateral "carport" and nothing said what one cost, so nothing scored it. You
could lose the worst steel in the game and pay for a $15 shackle. One broken
corner is enough (the gnome needs two: it needs the sail to land on it; the
carport doesn't need the sail at all), priced per structure so two beams is one
carport gone, not $360. The wreck swaps on the same event — E built it to the
same origin for exactly this.
VENTURI (C's question). There was no disagreement to settle. weather.core
aligns on |dot(wind, axis)| because a gap funnels either way through it, so an
axis is a LINE: -1.08 + PI = 2.0616, and my shipped 2.1 was the same gap read
from the other end. Took C's number because C MEASURED it off storm_03b and I
eyeballed mine at authoring time; the 2.2 deg of my eyeballing was worth
0.44 m/s. gain left at C's 1.35 — that's a balance lever, theirs with B's audit.
Also wired validateSiteWind at site load, C's ask from Sprint 10.
selftest 300/0/0 (was 296).
The water arc, carried since Sprint 3. Rain (Lane C's rainMmPerHour x the
exported RAIN_TIME_COMPRESSION, never hardcoded) lands on each node's
horizontal projection, runs down its steepest of 8 neighbours, and pools
where it can't get out. A flat sail's belly is a basin water flows into
and can't climb from; a hypar drains along its saddle ridge to the low
corners and off — so ponding cannot pincer §7, and measured on real yard
quads a flat rig holds 12 kg/m² vs a twisted rig's 1.7.
The 8-neighbour graph is load-bearing: a 4-way one can't follow the
saddle's diagonal ridge, so it trapped water in the gravity belly and a
hypar pooled as much as a flat sail. Steepest-GRADIENT descent (not
steepest drop) because a diagonal is √2 farther.
Gate 1, in asserts: a flat carport rig under a capped wind survives dry
(4/4) and dies wet (a corner at t=85s) — the control isolates water from
wind — and the broom saves it. Plus dump-on-break, dump-on-tension-up
(the turnbuckle counter-play), mass conservation, and a belly-tear safety
valve at 4 m of sag.
API for D and A, frozen in contracts.js: pondMass(), pondCentroid(),
drainPondAt(node, dt) -> kg-on-your-head. session.reset() for A's "play
again".
On D's tn-1.04 cliff: investigating it IS what surfaced the ponding load
regime. The 10 kN "spike" is real physics, not solver divergence — a
155 m² flat sail holding 2100 kg of water genuinely pulls ~21 kN, stays
finite, and tracks the water. So no physics-altering clamp (the
displacement clamp I tried moved the thesis 39->34%); instead an opt-in
`watchDivergence` tripwire that throws with a repro above 80 kN, live in
every selftest rig and never false-tripping, and a belly-tear that bounds
the runaway physically. Full writeup for D in THREADS.

SPRINT2 decisions 3 and 5, plus Lane A's fog nit.
Decision 3 — gusts now descend. Cloth pressure goes with dot(wind, normal); a
flat panel's normal points at the sky, so in a perfectly horizontal wind the
dot is ~0 and "lie it flat and ignore the storm" was the cheapest winning rig.
A gust front is descending air, not just faster air. Per-gust downdraft
fraction in storm JSON (storm_02 0.3, storm_01 0.18, default 0.25, validated
0..1), each gust varying 0.6-1.4x. Peak downdraft in storm_02 is 4.4 m/s, 17%
of the horizontal. Lane B: the cloth-side assert is yours.
The vertical draws from its OWN rng stream, and there's an assert pinning
that: pulling it from the main stream would shift every subsequent (t0, pow)
and silently re-time storms Lane A has already hand-verified. Their carabiner
still blows at t=45.4 and cascades at t=56.
speedAt() stays horizontal — an anemometer doesn't read falling air, and a
wind meter that spikes because a gust is descending reads as a bug.
Decision 5 — debris.pieces frozen and documented in contracts.js as the seam
Lane B reads in sail.step(), with the sphere/SI/mutated-in-place semantics
spelled out and an assert tying the live shape to the contract table.
Fog: dispose() captured scene.fog by reference and step() mutates that object
in place, so restoring it restored nothing (Lane A caught it). Now captured by
value, and fog we created ourselves is removed rather than left behind.
Selftest 130/0/0 (was 121); Lane C 28 asserts.

Decision 4 — conform to Lane D's call sites rather than the reverse (D
landed first and duck-typed them): repair(i), trim(i, delta) and
cornerPos(i). repair takes no hardware argument because prep sells
exactly one kind of spare, so it re-rigs at shackle grade — an upgrade
on a blown carabiner, a downgrade on a blown rated shackle, which is the
prototype's behaviour and a real choice about which corner you run to.
cornerPos returns a fresh vector at the live node, so a blown corner's
prompt chases the flogging corner instead of sitting on a dead anchor
(measured: 13 m off). All three are contract entries now, not PROPOSED
comments, so the merge tripwire enforces the seam.
Decision 5 — sail.step() takes an optional debris and applies sphere-vs-
cloth impulses. The exchange is symmetric: every newton-second the cloth
takes out of a crate, the crate loses. Asserted, and it conserves to
0.000% on an interior hit. Pinned corners are the deliberate exception —
invMass 0 means a crate off a corner dumps its momentum into the house,
which is correct, the anchor is bolted to a wall.
Note this leaves debris.js's applyToSail dead: it guards on `sail.nodes`,
which never existed on the rig — the cloth stores Float64Arrays. So the
debris-vs-sail impulse has been silently doing nothing in the assembled
game. Decision 5 puts it on this side; flagged for Lane C in THREADS.
The contact radius is swept by the piece's travel because main.js steps
the sail before the debris (so piece positions are a frame stale) and a
0.3 m crate at 25 m/s covers 0.42 m per frame — enough to pass clean
between cloth nodes.
Also: coverageOver() rays now start at heightAt(x,z) rather than y=0.

Rebased onto M0 and reconciled against the real spine. checkContract
('sailRig') now conforms and js/tests/b.test.js runs 28 asserts green.
Contract fixes:
- anchor.sway(t) is the ABSOLUTE position, not an offset (thanks A —
I had it adding sway to pos, which would have flung every
tree-anchored corner to double its coordinates).
- events is an Emitter emitting {type, corner}, not a drained array.
- coverageOver() rects are centre+size, matching world.gardenBed. It
consumes world.sunDir directly: a hit along sunDir means shaded.
- START_BUDGET/SPARE_COST/HARDWARE/FIXED_DT now come from contracts.js
rather than being redeclared here.
Bug: a corner that blew was marked broken but never had its mass
returned, so invMass stayed 0 and the "blown" corner sat welded in
mid-air — no flogging, and the sail silently went dead. PLAN3D §5-B
wants flogging emergent from the freed node, so _checkFailure now frees
it. The cascade test missed this because it called _repin() by hand;
the new test drives a real overload failure instead and asserts the
corner tears 2 m off its anchor and keeps moving.
Tension dial remapped from the prototype's rest/tension to a real
pre-strain. rest/tension asks for 17% strain at dial 1.2 and 29% at 1.4
— stretching an 18 m sail by three metres — and put 68 kN on a corner of
the yard's biggest quad with no wind blowing. At 0.10 strain-per-dial it
swings a 5x5 rig's peak load 2.1x loose-to-tight and redlines a 192 m2
quad at 8.3 kN drum-tight, which is punishing and correct.
HARDWARE ratings retuned in contracts.js to real newtons per the
standing note there that Lane B owns these numbers. Costs and tier shape
untouched; $80 still buys rated hardware on at most 2 of 4 corners.

Types, tuning constants ported from the prototype, a seeded PRNG and Emitter,
plus checkContract() — the tripwire that catches a lane drifting from its
interface at merge time instead of three lanes later.
createStubWind() ports the prototype's gust shape (telegraph 1.5s, ramp 0.8s,
hold 1.7s, fade 1.0s) so B and D can develop before Lane C lands weather.js.
Its schedule is precomputed at construction, which keeps sample() pure in t —
the selftest samples out of order and must get the same answer.
