The gate-1 diagnosis the sprint chartered, inverted by measurement: the shadow geometry is exact (probe2: raycast and rasteriser agree 1.0000/1.0000), the canonical measuring lines just don't cover the bed against vertical hail, and site_02's tr1+q1+q3+q4 at exactly $80 already separates 91.5 FULL vs 35.7 bare (sep 55.8, 0/4 lost) with no model change. Full findings + separation-target proposal in THREADS. Re-verified after the authoring session died un-pushed: all headline numbers reproduce; the bench drives RiggingSession.commit(rig) -> rig.attach(), not the bypassed-attach seam D's landmine names; balance.test's canonical shade-cloth peaks reproduce per-anchor to the last digit. One fix over the original staging: probe3/probe4 labelled per-corner peaks in plan order, but rig.corners is ring order — labels now come from corners[k].anchorId (values were always true; the $80 line's two RATED corners read swapped). Selftest 335/0/0. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

// THE PARETO QUESTION, and the whole of gate 1.
|
|
//
|
|
// probe2 proved the shadow model is sound (a sail over the bed reads 1.000 by
|
|
// raycast AND by the grid). probe3 found the variable: _checkFailure compares
|
|
// load against hw.rating * anchor.ratingHint, and the HOUSE fascia's hint is
|
|
// 0.35 — so a $30 RATED shackle is worth 2.3 kN on the house and 6.5 kN on a
|
|
// post. Every quad that covers the bed hangs off the house.
|
|
//
|
|
// So: sweep every 4-anchor line on the BEST steel in the game, settle it the way
|
|
// prep does, and ask both questions at once — does it HOLD, and does it COVER?
|
|
// A quad that covers 100% while tearing itself apart in prep covers nothing.
|
|
// This is the table the garden's whole design rests on and nobody has ever
|
|
// printed it.
