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.

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.

weichen	1d6b8a64a6	Add login page, forced password change, and admin user management Why: accounts are admin-issued (user decision 2026-09-30, no self registration); initial and admin-reset passwords must force a change on first login. Evidence: - LoginPage: password (primary) + API key tabs; ChangePasswordGate blocks the app until the forced change completes (mismatch/length validation inline); App auth state machine checking -> login -> mustchange -> ok, session cookie flows through fetch automatically. - Account menu gains change-password and admin-only user management; AdminUsersModal: create account (random initial password generator, admin checkbox), reset password, status table (ADMIN/USER, pending change chips). - Fixed a real bug found in the headless walk: menu toggles passed e.currentTarget into the setState updater where React nulls it by render time, so anchor was null and the menu never rendered; capture the element before the updater. - Headless journey on the real binary with --auth on: admin bootstrap via CLI -> first-login forced change -> app; admin creates bob (bob sees no user management); alice reset via CLI -> forced change on next login; API-key tab login; logout; zero console errors. npm run build + vitest green; make test full suite exit 0. Impact: replaces the old API-key-only LoginGate; embedded no-auth mode unchanged (no login page shown).

weichen	dc70399d45	Rebuild the left nav as a task-centric sidebar (option A, R1) Why: creation entries were split (project + at sidebar top-left, new session at bottom-left) and the project tree forced per-project navigation; the approved option A design makes one primary New Task entry, organization a view mode, and identity always present. Evidence: - New TaskSidebar: single New Task split button (current-project context, Cmd-N, secondary menu for new project / new task in project), project <-> timeline organization with persisted collapse, pinned section, archive view toggle, hover row actions, account footer fed by /api/me (embedded mode shows local tenant; logout clears the key), workspace icon strip retained (D25 shared list with Cmd-1..9). - store: tasks = cross-project list via GET /api/conversations; openTask switches project context; pin/archive optimistic + refresh; last project context persisted; stale conversations field removed. - tasklist.ts pure helpers + 6 vitest cases; npm run build passes; headless walk on the real binary: cross-project open, pinned-first, archive hide/show/restore, new-task flow, zero console errors. Impact: ProjectNav removed; contracts.ts regenerated from core (pinned/archived); no composer/right-pane changes (D25/D26/D31 intact).

weichen	4abf13d33d	Mirror the prompt module contract and add the library API Why: the backend prompt library ships new contract shapes and an endpoint; the frontend mirror and api binding keep the TS side in sync for upcoming management UI. Evidence: tsc + vite build green as part of composite make test. Impact: contracts.ts gains PromptModule/Trigger and AgentProfile.promptModules; api gains listPromptModules. No UI change yet.

weichen	616795be41	Show the live streaming bubble and fix markdown spacing Why: during a run nothing was rendered (the assistant message only lands at completion, so the LiveState projection never hit the screen), and white-space:pre-wrap on .part-text turned marked's inter-block newlines into blank lines, giving ordered lists a huge per-item gap. A latent race also wiped thinking/tool/phase state that arrived before the send POST resolved, and thinking text ran inline with the answer. Evidence: headless playwright against the mock backend shows the live bar, an expanded thinking panel, tool chips and incremental text with a blinking cursor mid-run; list item gaps measure 2.1px with white-space:normal; make test (frontend 9 tests) green. Impact: users watch thinking, tool calls and the answer stream in real time; markdown typography (lists, tables, quotes, headings) is compact; terminal runs fold the process trail behind a summary.

weichen	a54022c438	Constrain the chat column height so the message stream scrolls Why: .chat is a column-flex item of .main without min-height:0, so its content-based automatic minimum height grew past the viewport; .chat-body never overflowed (never scrolled) and the input bar was pushed off-screen. Evidence: headless Chromium on mock serve, 1024x620: before .chat=2130px and input-bar bottom=717 (>viewport), chat-body scrollable=false; after .chat=620, chat-body clientH 501 / scrollH 2011 with wheel scroll moving 600px up and back to bottom, input-bar bottom=620. Variants (empty conversation, single short message, 1024x400, 720x600) keep the input visible. Full combo make test green. Impact: chat page was unusable beyond one screen of content; single CSS rule chain, no behavior change elsewhere. Refs: Agent-System-Dev task card feature/chat-scroll-fix.	2026-09-30 09:15:45 +00:00

weichen	4f4711a22a	Add the tidy action and collapsed-rail pending badge (T5) Why: T5 notification strategy - the collapsed right rail must still surface the pending count (badge), and the inbox needs a one-key tidy (done cards dismissed; resolved verdicts keep their stamp). Evidence: tsc clean; vitest 9/9; vite build ok; delegation-only logic. Impact: App collapsed rail badge, store tidyCards (done->dismiss via existing cardDismiss), Workbench tidy button, styles.
