From f9fe75f122818c14adf321405742a73533e8da40 Mon Sep 17 00:00:00 2001 From: m3ultra Date: Fri, 17 Jul 2026 13:10:40 +1000 Subject: [PATCH 1/2] Gate 0' CLOSED: the harnesses agree. Losing 2 corners is the shop MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Drove the live game — settled through prep, rig verified unchanged across the phase boundary (contaminated: false) — and it returns hp 58, 2 lost. This suite returns hp 57, 2 lost. A's hp 58 was right and reproduces to a point; A's "1 lost" was the miscount. The two harnesses now agree on both numbers and the dispute is over. All three SPRINT8 candidates tested; none flips the corner count: V1 settle under live calm wind + world.update sway -> 2 lost, t2 4.4 V2 ... and live sway through the storm too -> 2 lost, t2 4.6 (worse) V3 repair delayed 0 / 3 / 6 / 10 s (a real walk) -> 2 lost Nothing could flip it, because losing 2 is not a bug — it is the shop: t2 4.6 kN, t2b 3.5, p3 3.5 all need the $30 rated shackle; p4 2.9 takes a $15 shackle. Holding all four = $105, $120 with the spare a repair needs. Budget is $80. Three corners sit above shackle grade and $80 buys two, so the wild night's best line ends hp 58 with the garden alive and the rig dead. That is SPRINT8's escape hatch, and it's a design question handed to A: `lost < 2` calls this a loss, DESIGN.md calls it the story. The assert now asserts the half that IS physics (the garden must survive, hp >= 50) and reports the corner count as the open question, so the suite states the measurement rather than pre-empting A's ruling. Landed D's settled-at-entry guard, as a windowed TREND test rather than an instantaneous one: measured, the worst corner oscillates 0.9 -> 1.9 -> 1.3 -> 1.7 kN under constant wind because damping is deliberately light, so there is no single settled value and a "has it stopped moving" check can never pass — it would just be a flaky assert someone deletes. Comparing consecutive 2 s means catches a real transient and tolerates the breathing. Same lesson as the statics assert in sail.selftest. Selftest: 266 passed, 0 failed, 0 skipped — green for the first time since SPRINT6.
