From 4d83ba5620f011ab4a1d2925e66ae02c2c9cf7a7 Mon Sep 17 00:00:00 2001 From: Erik Date: Sat, 23 May 2026 20:13:24 +0200 Subject: [PATCH] =?UTF-8?q?docs(claude.md):=20A6.P3=20#98=20=E2=80=94=20po?= =?UTF-8?q?int=20at=20evening-v2=20findings=20doc?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds the "Evening extension v2" paragraph documenting the apparatus ship + root cause identification from the 2026-05-23 PM-late session. The block names: - The four commits that landed (fb5fba6 → 44614ab → 0f2db62 → f29c9d5) - The apparatus: PhysicsResolveCapture + LiveCompare_* tests - The root cause: cottage GfxObj 0xA9B47900 (landblock-baked static building) blocks the head sphere at world Z=94.0 with cn=(0,0,-1) - User's confirming observation about jumping (rules out step-up hypotheses) - The cap geometry math (foot Z=92.74 + sphereHeight 1.20) - Documents-the-bug pattern for the first-cap test - Test baseline (1178 + 8 serial) - Pointer to the new findings doc as canonical pickup - Concrete next-session move (extract cottage GfxObj polygons) Co-Authored-By: Claude Opus 4.7 (1M context) --- CLAUDE.md | 33 +++++++++++++++++++++++++++++++++ 1 file changed, 33 insertions(+) diff --git a/CLAUDE.md b/CLAUDE.md index 22208cd..f92b3f8 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -812,6 +812,39 @@ captures live PlayerMovementController state and diffs against the test harness — evidence-first instead of speculation-first.
