Why: Independent review found component-local color derivation, a private transition, and missing dark/molv coverage in the visual candidate.
Evidence: Frontend design guard passes and 19 Playwright scenarios cover light, dark, molv, and 320-1920px layouts.
Impact: Keeps the approved visual direction while moving color ownership to @ui tokens and removing private motion.
Refs: Agent-System-Dev feature/workbench-visual-redesign
Why: The inherited light-theme divider and hover treatment disappeared inside the new inverse create button.
Evidence: Focused browser layout test and production build pass locally.
Impact: Changes only the create action divider and hover surface.
Refs: Agent-System-Dev feature/workbench-visual-redesign
Why: Spacing-only refinements still looked like the original flat gray workspace and did not satisfy the approved visual redesign.
Evidence: 272 unit tests, 16 browser scenarios across 320-1920px, and the production build pass locally.
Impact: Gives navigation, authored messages, assistant results, and work details clearly different visual surfaces while preserving behavior.
Refs: Agent-System-Dev feature/workbench-visual-redesign
Why: The three-column workspace read as flat and visually scattered, making conversation, current work, and navigation difficult to distinguish.
Evidence: 272 unit tests, 16 focused browser scenarios across 320-1920px, and the production build pass locally.
Impact: Refines the existing workbench presentation without changing its data flow or fast/slow task behavior.
Refs: Agent-System-Dev feature/workbench-visual-redesign
Why: Fast and slow channel cards duplicate across panes and completed replies hide process output.
Evidence: npm test; npm run build; 12 isolated Playwright scenarios with reload and responsive widths.
Impact: Preserve ordered folded process history, load durable run events, and give work cards one detailed pane.
Refs: Agent-System-Dev feature/work-companion-visibility UI1 UI2 UI3
Why: make material, background work, confirmations and files accessible to nontechnical users across desktop and mobile.
Evidence: Dev SELF receipts for Frontend tsc, 190 tests, knip baseline, build, nine fixture browser cases and two real HTTP/browser smoke cases using MockRunner.
Impact: existing API and permissions remain authoritative; stale events/queries and duplicate effects are guarded, while one file preview and reading state are preserved.
