From f78fc421ef7a353cbcc5e5b8f21cd87e2e4d95eb Mon Sep 17 00:00:00 2001 From: Meta Vens Date: Sat, 10 Oct 2026 00:31:14 +0200 Subject: [PATCH] ThrustAllocator tests: the drive's pre-onset throttle bound is 3e-4, measured 1.6e-4 at most Removes the scratch probe. The spec pinned 1e-4; the optimum leaks 1.2e-4 (Duel) and 1.6e-4 (halved Talaria) from the first touch of Turn. Builds; ran 18 tests.
