+# 2026-07-10 — Tick: remove stale Material preview section from bevy.md
+
+```
+Type: log
+```
+
+## Intent
+
+Tick audit of the context-menu / machine-work slice found a stale
+"Material preview" bullet in `wiki/interface/bevy.md` claiming "the flat
+sensorium remains the default," contradicting both the code
+(`RenderMode::default()` has `material: true` since 2026-07-08) and the
+same page's own "Material render (default)" section. A stray duplicate
+fragment from the People panel section was also lodged inside the
+Material render section.
+
+## Changed
+
+- Removed the stale "Material preview" bullet (fully superseded by the
+  "Material render (default)" section and the Controls F3 line).
+- Removed the stray "status. The header repeats trace debt..." fragment
+  (a duplicate of the People panel section text).
+
+## Checks
+
+`./tools/check.sh --docs`.
+
+## Spec impact
+
+Knowledge correction only — no law, spec, or behavior change.

 - Intent: Stop parallel landings from hand-unioning `wiki/log/DEVLOG.md` and `wiki/process/specs.md`. Session logs and spec frontmatter are the sources; indexes are regenerated.
