From d1c3f2b09d1e3e0d2aaa100d499e2aac6f3947fe Mon Sep 17 00:00:00 2001 From: LANE-SIM Date: Fri, 17 Jul 2026 18:35:47 +1000 Subject: [PATCH] [sim] round 3 NOTES Confirms the units conversion (bufferCap 240 = 8.0s of cover at a 30/s deficit) and reports scram survival: first scram t434, restart t934, ~718-tick duty cycle, ZERO brownout ticks across 20k, melt rate unchanged. For the orchestrator: - heat semantics need a one-line ruling. heatPerTick is GROSS in my model (net = heatPerTick - coolPerTick). DATA's committed 0.0025 against the 0.004 default nets negative -- the decoder could never scram. Their in-flight 0.0033/0.001 works, so we agree by luck of timing. - the codex's literal bloom loop is not expressible with per-grade recipes - asic-cooler does nothing without a spatial heat mechanic - my sim code landed inside 45003db [ui] REMOVE mode: the shared tree has one git index and an add-everything commit in another session swept it. Not a UI ownership violation. Suggest a no-`git add -A` rule.
