Consume the UI capability platform: shared icons/avatars, settings shell

Why: avatars, cards, and settings are base capabilities now (user decision 2026-09-30); the host must eat its own dogfood so plugins get the identical surfaces. Evidence: - Local icons.tsx removed; Icon/Avatar/BrandMark/primitives/Settings Shell imported from @ui; message stream gains avatar columns (user initial from /api/me name, assistant brand mark); SettingsModal rebuilt on SettingsShell (side-nav sections with badges, EmptyState for plugins, iconified actions); AdminUsersModal rows show shared avatars. - tsconfig paths pin react/react-dom types to the frontend copy — the source-composed ui package otherwise resolves a second @types/react through its own node_modules during make frontend (npm ci), which breaks type identity (surfaced by SVGProps crossing the boundary); vite dedupe already guarantees one runtime copy. - Headless on the real binary: avatar columns render, settings shell switches sections with badges, admin rows show avatars, zero console errors; build + vitest green. Impact: visual/structural only; no API or state changes. Refs: Agent-System-Documents proposal 2026-09-30-ui-redesign-and-auth.md

weichen	59ffe044b5	Consume the UI capability platform: shared icons/avatars, settings shell Why: avatars, cards, and settings are base capabilities now (user decision 2026-09-30); the host must eat its own dogfood so plugins get the identical surfaces. Evidence: - Local icons.tsx removed; Icon/Avatar/BrandMark/primitives/Settings Shell imported from @ui; message stream gains avatar columns (user initial from /api/me name, assistant brand mark); SettingsModal rebuilt on SettingsShell (side-nav sections with badges, EmptyState for plugins, iconified actions); AdminUsersModal rows show shared avatars. - tsconfig paths pin react/react-dom types to the frontend copy — the source-composed ui package otherwise resolves a second @types/react through its own node_modules during make frontend (npm ci), which breaks type identity (surfaced by SVGProps crossing the boundary); vite dedupe already guarantees one runtime copy. - Headless on the real binary: avatar columns render, settings shell switches sections with badges, admin rows show avatars, zero console errors; build + vitest green. Impact: visual/structural only; no API or state changes. Refs: Agent-System-Documents proposal 2026-09-30-ui-redesign-and-auth.md	2026-09-30 14:22:37 +00:00

weichen	9fc1387235	Restyle the whole UI: linear icon set, layered surfaces, refined chrome Why: user feedback (2026-09-30) — the UI still lacked the polish and modern feel of ZCode; per its design system (calm/dense/operational) this is the R4 visual convergence pass. Evidence: - New icons.tsx: 32 Lucide-style linear SVG icons replacing every emoji/ glyph (grep for the old glyph set now returns 0 in components); brand mark + workspace-icon mapping shared by sidebar, rail, login, menus. - Login/change gates gain a wide-screen brand panel (gradient + radial glows + feature list), segmented tabs, focus-ring inputs, glowing submit; sidebar gets a solid accent New Task CTA, inline-icon search, selected task with accent bar, hover-reveal row actions, account footer chips; chat area gains floating rounded composer with focus glow, calmer header/tool blocks, greener HITL confirmations, empty state mark; modals gain backdrop blur + spring-in. - Two headless review iterations on the real binary (--auth on, both themes): fixed bubble padding, headline break, and lifted the panel step for clearer three-column separation; final walk shows 21 SVGs, zero leftover glyphs, zero console errors, build + vitest + full make test green. Impact: pure visual layer (CSS + icon components + class-level JSX); no behavior, API, or state changes; both themes driven by the new token scale in the ui repo.
