From dd78d323f37a5a5ea9e23df878fa209dd1501098 Mon Sep 17 00:00:00 2001 From: Cyd Date: Sun, 19 Jul 2026 16:29:16 -0500 Subject: [PATCH] e0test: check-exchange acceptance stage for edit 6; record RC1 first-light MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit After the flip leaves counters over threshold, the tool now sends a CheckRequest (ACKing every status frame) — edit-6 chips must repaint and re-render the E0 readout; 04000000 marks a pre-rc1 chip. Analysis records the stock-chip archaeology (stock also leaves 04000000, but the ungated E0 readout papered over it in period — our fixes exposed it) and RC1's below-threshold first-light PASS (version+check -> F0).
