RiggingSession already held every rule and was tested headless; this is
only the hands. Click an anchor to rig it, click again to cycle its
hardware, shift-click to pull it off for a full refund, [ and ] for
tension, S for the spare. RMB is left alone — that's the camera's orbit.
Enter stays Lane A's: the phase machine calls commit(), which goes
through main.js's rigSail() door as A asked.
It renders its own anchor markers because the yard has none to raycast
against — world.js builds posts and trunks, not pick targets — and
marker styling is prep-phase UI, so it belongs to this lane.
What you click is not what you see: the marker ring's tube is 5 cm, which
at yard distance is a couple of pixels and genuinely unhittable. Picking
goes against an invisible 0.45 m sphere and the ring is just the read.
The panel shows live sail AREA, which SPRINT2 doesn't ask for but
decision 2 implies: the 70-192 m² problem is invisible to a player who
can't see what they're about to build. Picking the obvious quad
(h1/h3/p1/p2) now says "191 m2" before you commit to it.
dev_rigging.html follows the house pattern (C's weather_demo, D's
dev_player): the picking UI can't be asserted headless — it is clicks,
raycasts and materials — and can't run in index.html until A wires step
8. It boots the real world.js, real anchors and real cloth, so what's
verified is what ships. Retire it once index.html hosts prep.
Verified by hand in it: rig h2 by click, cycle carabiner -> shackle,
budget $80 -> $65, weak link flagged, dashed quad preview, commit ->
sail in scene (100 verts, 162 tris, casting a real shadow over the
garden bed) -> storm with corner loads reading 1.0-1.2 kN.

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.

Ports the prototype's economy verbatim: $80 budget, $5/$15/$30 hardware
tiers, $15 spare, tension 0.6-1.4. Adds unrig-with-refund, which the
prototype lacked — a misclick there was unrecoverable, and a full refund
costs the economy nothing.
RiggingSession holds all the rules and is three-free and DOM-free, so it
tests headless. The picking UI is left as an explicit seam: it needs Lane
A's camera and anchor markers to raycast against, which do not exist yet.
One assert encodes a design invariant rather than a code fact: $80 must
not buy rated shackles on all four corners. DESIGN.md's economic tension
is that you always field one dodgy corner and choose which one; if that
test ever passes, the budget has become decoration.
