Preserve part order, wire artifact downloads, and upgrade file management

Why: AssistantMessage reordered a message's parts by the process flag, so tool calls floated above the text that surrounded them instead of appearing where they actually ran; live streams had the same defect via a fixed template order and never showed artifacts mid-run. Generated files (e.g. meeting-minutes docx) had no visible download path, the artifacts panel was a bare list, DocViewer nested a modal inside the overlay, and settings rows used a legacy grid with a floating save button. Evidence: messageparts.ts adds groupParts (order-preserving grouping of consecutive process parts, unit-tested) plus humanSize/artifactIcon helpers; Conversation renders blocks in original order and the artifact chip becomes icon + open + download; LiveState.parts accumulates events in arrival order including artifact_ref so live view matches the persisted message; ArtifactsPanel gains search/kind filter/upload and per-row preview/download/delete-confirm; DocViewer is a single-layer OverlayHost with pdf iframe, csv/json monospace, and a binary info card with a download CTA; SettingsModal migrates to @ui SettingRow with the save button pinned in the shell actions bar; inbox cards receive the docBridge so result cards can open artifacts. tsc clean, vitest 20 passed, production build succeeds. Impact: message timelines read in true execution order during and after runs; every artifact is previewable and downloadable from the message chip, the workspace panel, and the viewer; settings render on the fixed two-column shell. Refs: task feature/chat-order-artifact-files (ui# c3e1f3b backend# 44b51fa).

Author	SHA1	Message	Date
weichen	edb5dbe73e	Preserve part order, wire artifact downloads, and upgrade file management Why: AssistantMessage reordered a message's parts by the process flag, so tool calls floated above the text that surrounded them instead of appearing where they actually ran; live streams had the same defect via a fixed template order and never showed artifacts mid-run. Generated files (e.g. meeting-minutes docx) had no visible download path, the artifacts panel was a bare list, DocViewer nested a modal inside the overlay, and settings rows used a legacy grid with a floating save button. Evidence: messageparts.ts adds groupParts (order-preserving grouping of consecutive process parts, unit-tested) plus humanSize/artifactIcon helpers; Conversation renders blocks in original order and the artifact chip becomes icon + open + download; LiveState.parts accumulates events in arrival order including artifact_ref so live view matches the persisted message; ArtifactsPanel gains search/kind filter/upload and per-row preview/download/delete-confirm; DocViewer is a single-layer OverlayHost with pdf iframe, csv/json monospace, and a binary info card with a download CTA; SettingsModal migrates to @ui SettingRow with the save button pinned in the shell actions bar; inbox cards receive the docBridge so result cards can open artifacts. tsc clean, vitest 20 passed, production build succeeds. Impact: message timelines read in true execution order during and after runs; every artifact is previewable and downloadable from the message chip, the workspace panel, and the viewer; settings render on the fixed two-column shell.

weichen	a3c556cd0a	Surface cross-session controls in the UI with a project settings panel Why: the layered permission model (project gate + per-conversation outbound/inbound flags) shipped in Backend PR #18 needs visible controls; project scope also had no settings UI yet though the API existed. Evidence: npm run build (tsc -b + vite build) and npm test (15/15) pass. Impact: new schema-driven ProjectSettingsModal (first project-scope settings surface, writes putProjectSettings, reuses SettingsModal group/input helpers); TaskSidebar gains a private shield on rows and in the row menu, per-conversation allowCrossRead in the row menu, and a project-settings gear on project group heads; Conversation header gains a cross-read toggle; contracts/api/store carry the new flags.

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.
