Implementation plan

Design and review

Apply frontend-design, emil-design-eng, apple-design and karpathy-guidelines. Existing system sans, primary titles and secondary path/shortcut roles; current canvas/view/text/border/accent tokens stay. Signal dark examples remain canvas #090909, view #111113. Workspace prefixes reuse sidebar::mark/set_mark. Command glyphs are 16px in a 20px prefix lane, neutral currentColor at existing secondary contrast; high contrast restores full foreground. No command badge background.

T3 Code CommandPaletteResults.tsx at 50647de0143e68fde051eb1a0ccf4fe63f9947b2 places item icons before title/description and shortcut afterward. Translate that sequence to native ActionRow prefixes and suffixes. Existing groups/search/activation remain. GNOME symbolic icon guidance supports simple recognizable monochrome glyphs: https://developer.gnome.org/hig/guidelines/ui-icons.html . Do not copy T3 assets or web palette.

Review against brief: workspace marks connect the same entities across surfaces; command category icons reinforce labels without making every row a new colored badge. Keep native widgets and no new assets/dependencies. A secondary command icon should not reduce shortcut legibility; verify real narrow/enlarged allocations before acceptance.

Technical design

Add bundled icon metadata to the existing action registry. Palette Target::Action references its static ActionDef instead of storing a formatted name; both icon and activation identity come from one registry row. Build one decorative prefix per native ActionRow; workspace rows retain their ID target and use the shared mark. Existing ActionRow logical prefix placement handles RTL. Add only scoped icon CSS.

Sequence and checks

Extend existing native palette tests first and demonstrate red for missing prefixes. Verify workspace mark/tint, command glyph roles, decorative accessibility role, prefix geometry, existing shortcut/selection/target mapping, RTL and all action icon resolution without external themes. Implement, inspect desktop light/dark/narrow/large/high-contrast/RTL captures. Independent Spec/Standards review, durable evidence and docs precede source freeze. Full and fresh delivery proof before publish/link; latest CI/reviews before authorized merge.

Constitution and contracts

Rust 1.94 development/minimum 1.92, existing GTK4/libadwaita. No domain model, persisted data or IPC contract changes; UI registry remains toolkit-facing. No load-bearing architecture choice. Display tests necessary for allocation and native accessibility roles; manual AT/IME not certified by Xvfb. All principles satisfied.

CI correction

The proposed-merge CI exposed command truncation at 360px with wider font metrics. Reproduce with DejaVu Sans18, then use the native max-width480sp breakpoint to move shortcut text to the command subtitle and hide its trailing copy. Restore both properties automatically at spacious widths. Keep workspace subtitles unchanged. Verify narrow→wide→narrow restoration, both font families, RTL and class high contrast. No assertion is weakened; repeat independent delta review and full/delivery on frozen corrected source.
