   - **Icon weight mix `[human]`:** full-color Papirus icons in the
     menus vs all-monochrome bar glyphs — pick: symbolic/monochrome
     menu icons for one system, or color as the menu's identity.
+    A/B captured on lumon (iteration #46, side-by-side:
+    https://claude.ai/code/artifact/1ccd10fe-4b6f-454a-888d-e7fdf2362b03):
+    B (symbolic) matches the bar's weight but Papirus symbolic
+    coverage has holes (preferences-desktop-theme-symbolic missing —
+    Look & Feel lost its icon) and rofi tints symbolics a fixed dim
+    gray, not the theme text color — going B needs an icon audit +
+    recolor slice. A costs nothing. Awaiting the call; A stays until
+    then.
   - ✓ **Bar right-cluster rhythm** (shipped iteration #36): group
     margins before pulseaudio/powerprofile/battery — heads that
     self-hide degrade to the uniform spacing.

+## 2026-07-05 — icon-weight A/B for the human call (iteration #46, item 28)
+- **Task:** item 28's last `[human]` blocker — make the color-vs-
+  symbolic menu-icon decision cheap.
+- **Did:** captured the lumon root menu with `-symbolic` icon names
+  (temporary uncommitted rofi.nix edit, reverted after) and published
+  a side-by-side artifact (link in the BACKLOG bullet). Findings:
+  symbolic matches the bar's weight, but Papirus symbolic coverage
+  has holes and rofi tints symbolics fixed gray — B needs an
+  audit+recolor slice; A (color) is the free default.
+- **Verified:** V2 for the experiment itself (both variants VM-
+  captured); no repo code changed — tree is clean apart from agent/.
+- **Pending:** Bernardo's call on the artifact. Item 28 is now fully
+  agent-side done: all remaining bullets are `[human]`/hardware.
+- **Next suggestion:** general loop — item 15 slice (c) (per-profile
+  workspaces) is the topmost actionable code item; 14 fires Monday.

 ## 2026-07-05 — purge stub waybar.css whole-swaps (iteration #45, item 28c/d)
 - **Task:** item 28 — lumon vibe capture exposed four themes shipping
   an unstyled default bar.
