webclient: remove session list dividers, 42px sidebar logo, truncate long file names in preview pill

webclient: apply kit radii to content-cards and viewed-image thumbs, fix dead scss tokens ...

The content-card and ArtifactsPanel style blocks used @use 'kit-deps'
inside <style scoped> without lang=scss, so sass never ran: the
-radius-md token stayed a literal in the built CSS and the
browser saw border-radius: -radius-md (invalid → 0 corners).
Both blocks now declare lang=scss and compile to the kit's 6px radius.

Also rounds the corners of user-message image attachments and adds the
missing label prop on the tools-collapse icon button (kit dev warning).

webclient: cap thinking body at 800px, smooth details close, Navi-viewed images grouped in artifacts ...

- thinking-body: max-height 800px + inner scroll so long reasoning
  doesn't grow the whole chat
- content-card: body stays mounted after first open (no v-show teardown
  at toggle time) — ::details-content now has real content to shrink,
  so collapsing animates smoothly instead of snapping to 0 in a frame
- synthetic '[Image loaded via ...]' messages from vision tools are no
  longer rendered as user bubbles; their images are collected (live from
  tool_call metadata, and from history) into a viewed-images group at
  the top of the artifacts tab, thumbnails open the lightbox

webclient: tool-count badge, kit-styled content card, thinking corner gap, chat top gap, drop duplicate reconnect notice

webclient + navi: session title click-to-rename; empty rename regenerates via LLM

webclient: profile chips in sidebar; New Chat opens welcome; profile tap starts session; welcome grid 4-up

webclient: mobile input bar flush; settings panels full container width ...

- .input-bar on mobile: no top/bottom padding — once attachments appear,
  the file strip provides the gaps itself
- ApiKeys / Notifications panels: drop the 800px cap, fill the centered
  1200px settings column

webclient: polish batch — caps off, kit badge/chip in header+input, search clear closes, mobile full-bleed input, settings centered ...

- chat-header-title and sidebar logo span: remove forced uppercase
- profile badge -> GnBadge (variant per profile: secretary secondary,
  server_admin warning, developer info); custom box styles dropped
- pending file pill -> GnChip (icon + removable); image thumb stays
  app-owned (no kit image-preview component) but on kit surface look
- sidebar search clear button now also closes the field
- input-row: no yellow focus ring; on mobile full-screen width, no
  borders, inner padding carries the breathing room
- sidebar footer: without-hover removed from gear/admin/logout buttons
  — kit hover returns
- settings: header and body centered, max-width 1200px

webclient: V1–V3 — visible kit 1.0 pass on input bar, sidebar and chat cards ...

- Input row shaped exactly like a kit input (panel-muted, 2px muted
  border, 3px radius, hover/focus-within states)
- Sidebar: uppercase NAVI logo, row separators, session names in
  text-light, uppercase chat header title
- Chat surfaces: 6px radius on thinking/plan/tool/subagent/summary
  cards, summary card switched to muted border + info accent stripe,
  user bubble radius, pill radius on file pills, kit radii on
  code-block and markdown image links, 6px accent quote stripe in
  tool results
- dist rebuilt on kit 1.0

webclient: W4 — chat empty state -> GnEmptyState, card modal -> GnModal ...

- ChatArea: .empty-chat custom icon+text -> GnEmptyState card
  (keep .empty-chat wrapper only for centering)
- CardGrid: inline Teleport modal (overlay/close/scroll bespoke chrome
  removed) -> GnModal; .card-modal/.card-modal-title class names kept
  inside the new DOM (test contract); kit header slot renders the title
- WelcomeScreen: typography aligned to kit (30px h1, 14px base),
  profile cards get -radius-md, dead .profile-icon style dropped
- CardGrid test: mount with the kit plugin (GnModal resolves),
  two nextTicks for the post-flush open watcher

Verified: vitest 111 passed, build OK, welcome screenshot unchanged
(modal/empty-state visually checked after final build)

webclient: W3 — migrate settings/sidebar/chip surfaces onto kit components ...

- AppSidebar: hand-styled <select> -> GnSelect (options computed from the
  profiles store); the ~60-line bespoke select styling in app.scss is now
  three compact overrides collapsing GnSelect's form chrome for the slim
  sidebar row
- ApiKeysPanel: bespoke grid-table -> GnTable with cell slots (monospace
  key prefix, formatted dates, revoke GnIconButton in actions); loading
  state -> GnLoader; no-auth callout -> GnAlert(variant=warning)
- NotificationSettingsPanel: unsupported-browser callout -> GnAlert(info)
- SettingsView: header -> GnPageHeader (compact) with sidebar toggle in
  #actions
- ShowTokenModal: token field -> GnInputGroup + GnCopyButton (drops the
  bespoke copy/useCopy wiring)
- QueuedMessagesChip: .task-chip div -> GnChip (icon prop)

Verified: vitest 111 passed, build OK, screenshots of / and #settings

webclient: retokenize styles onto gn-ui-kit v1.0 CSS variables ...

All ~165 legacy var() usages (--color-*, --surface*, --accent*, --border,
--text*) with hex fallbacks and ~150 raw hex literals across app.scss and
24 scoped style blocks are swapped to the kit's --gn-* tokens per the
intent of the old fallback values:

- accent/primary/teal (#7aa2f7/#4ec9b0) -> --gn-color-secondary
- amber/orange highlights -> --gn-color-accent
- text greys -> --gn-color-text-{light,medium,dark}
- panels -> --gn-surface-panel; elevated tints -> color-mix over panel
- translucent overlays -> color-mix(in srgb, ..., transparent)

Deliberately literal: terminal deep bg #0f0f14 (darker than any token)
and the content-card image badge teal #89dceb (kit has no teal). File
type badges keep a categorical palette via nearest kit tokens.

Dead "UI kit overrides" block halved: kit 1.0 dropped hover icon
rotation, so only the app-owned chevron open-state flip remains.

Verified: vitest 111 passed, build OK, dev render matches W1 baseline

webclient: refresh vendored gnexus-ui-kit to v1.0.0 + dist-css wiring ...

- vendor 0.2.0 (snapshot d640a9e, ~93M with demo/node_modules) replaced
  with a clean 1.0.0 subset (4.5M): src/{js,scss,vue}, dist/{css,vue,js},
  dist assets (IBM Plex Mono fonts), docs, README/CLAUDE/AGENTS
- kit component CSS now consumed as prebuilt dist (import
  'gnexus-ui-kit/css' before app styles): kit 1.0 _fonts.scss uses
  relative url() for IBM Plex Mono, which breaks source compilation;
  the bundler resolves them into vendor dist/assets
- main.scss drops @use 'kit' as * (still broken by the font urls);
  kit-deps stays for focus_ring + SCSS tokens in app.scss and scoped
  blocks
- app.scss scrollbar block removed (kit.css 1.0 ships identical styles)
- vite.config: dead @kit alias removed; brand-new 'gnexus-ui-kit/css'
  alias now consumed
- product dist/ rebuilt (tracked: served by backend, deployed from git)

Verified: vitest 111 passed, vite build OK (ttf emitted, hashed),
preview screenshot renders dark kit theme with new density

webclient: virtualized message list (DynamicScroller) ...

- MessageList rewritten on vue-virtual-scroller DynamicScroller; only rows
  near the viewport mount (session switch 650-730ms longtask / DOM 31645 ->
  110-165ms / DOM 1-2.5k, zero freezes)
- scroller is keyed by session id: message ids repeat across sessions, so
  teardown drops the measured-size cache on switch
- convergeToBottom watches the bottom hold for a bounded window after
  landing (lazy row measurements nudge scrollHeight late); yields to wheel/
  pointer/touch input instead of scroll-position heuristics, which the
  scroller's own adjustments would trip
- renderMarkdown gets a byte-capped LRU memo so markdown remount cost is
  amortized while virtualized rows recycle
- removed dead .message-list/.message-list-inner styles

webclient: session-list polish from review pass ...

- documentTitle: persistent nameById map — names for sessions beyond the
  loaded list page (list only holds ~30); map filled by fetches and
  loadSession meta, never wiped by later refetches
- createSession: placeholder inserted at the position the server list
  would give it (after pinned run, last_active desc) so refetch no
  longer visibly moves the new row
- SessionItem: skip empty .session-icons wrapper when no icons
- drawer breakpoint made exclusive (-sidebar-drawer 1280 -> 1279.98):
  viewport of exactly 1280px now gets the desktop sidebar

webclient: loading indicators where the UI looked frozen ...

- session open: centered spinner in MessageList while chat.loading
- image paste/drop: imagesProcessing counter (chat store, shared);
  FilePreviewStrip shows spinner placeholder tiles where the resized
  previews will land
- file upload: indeterminate sliding bar instead of the fake static 60%
- send → run start gap: "Sending…" hint with spinner, cleared on
  stream_start / message_queued / stream end / error / session switch
- content-card images: skeleton with spinner until @load (reset on src
  change); wrapper keeps min-height while the img is empty

vitest 96 passed.

e2e fixes: tasks tool in profiles, bg timeout lift, stepIcon fix, queue semantics docs ...

E2E findings addressed:
- tasks tool was registered but not in any profile's tools.agent.native —
  added to all six profiles (agent could not check/wait/cancel bg tasks)
- detached terminal/code_exec/ssh_exec runs without explicit timeout are
  lifted to 300s: foreground defaults (20/30/60s) marked long commands
  'completed' with partial output while the process still ran
- ToolCard.vue: define stepIcon(status) — template referenced it but the
  function was missing (render crash on task_update step)
- message_queued reachability documented: WS read loop is sequential, the
  queue path is only reachable from a second socket/headless recall

webclient: background task chip, id-first tool matching, queued badge ...

- toolIndex (tool_call_id → card): exact matching for parallel batches and
  late events after stream_end; legacy name+pending fallback kept
- bare tool_call synthesizes a card so results are never lost
- task_update: backgroundTasks chip above composer + steps appended to the
  spawning tool card (parent_tool_call_id binding)
- message_queued badge, terminal_opened dispatch
- new BackgroundTasksChip component, task_update step rendering in ToolCard

webclient: code blocks span full message width in flex markdown container

renderers: colour diff line numbers + read line numbers, keep content neutral ...

Standard for diff and read output: the line number (and the +/- marker for
diffs) is the coloured anchor; the content itself reads plainly.

diff: "{num} {marker}  {content}" with num+marker in the marker colour
(green/red), content neutral. Fixed the number-column regex to "^( +)(\d+)|"
so files with more than 9 lines (width > 1) still match — the old
single-space pattern silently fell back to whole-line colouring.
read: "{num}: {content}" with the number in the accent colour, content
neutral (was dim number).

Applied to both clients: the TUI diff/filesystem renderers and the webclient
ToolCard (renderDiff / renderRead). The model-facing text from the server is
unchanged — this is display-only.

fix(recall): stabilize scheduled callback system and improve UX ...

Backend fixes:
- stop_session now stops headless recall runs via _busy_sessions dict
- _fire_recall sets user ContextVars so tools work correctly
- MaxIterationsReached treated as success, not failure
- skip_next_recall uses GREATEST(trigger_at, now) for overdue recalls
- schedule_recall rejects past trigger times
- timezone offset double-adjustment fixed for aware datetimes
- _fire_recall registers _AgentRun for reconnect/replay support
- session_sync race with stream_start fixed

Frontend improvements:
- Recall banner moved to ChatHeader with live Cancel/Skip buttons
- Recall messages styled with is_recall flag and badge
- Real-time recall updates via WebSocket (recall_update events)
- Recall filter moved to sessions-header as toggle button
- Session list shows clock icon for sessions with pending recall
- Empty state messages for empty/filtered session lists
- Fixed missing api import in ChatHeader.vue

Tests:
- Updated scheduler_loop tests for _busy_sessions dict change

Fix search spinner placement, msg-flash disappearance, results cleanup ...

- AppSidebar: spinner moved inside GnSearchField input-group-addon via CSS
  (:deep .input-group-addon overlay). Removed spinner from sessions-label.
- AppSidebar: closeSearch and handleSelect now call sessionsStore.exitSearch()
  and reload normal session list, so search results disappear after selection.
  toggleSearch restores previous query and re-activates search on reopen.
- CSS msg-flash: removed animation-fill-mode:both and background-color:transparent
  from keyframes, so message bubble keeps its original background after flash.
- SessionsStore: added exitSearch() method (preserves query, disables active flag).
- Tests pass (51/51)

Polish session search UX: GnSearchField, spinner, flash timing ...

- AppSidebar: use GnSearchField from gnexus-ui-kit, spinner during search,
  search toggle button always visible in sessions-header, hide search on select
- MessageList: fix msg-flash timing — make content visible before scrolling,
  extend flash duration to 2.5s with background + brightness
- CSS: enhance msg-flash keyframe animation
- Tests pass (51/51)

Add session search across messages with backend + frontend ...

Backend:
- GET /sessions now accepts `search` query param
- _session_summary computes match_indices and match_preview from messages
- pg_session_store: messages ILIKE added to search_list and count_all
- In-memory store: search_list also filters by message content

Frontend:
- AppSidebar: search toggle icon + debounced input, Ctrl+K shortcut
- SessionItem: highlight matching text, show match_preview from search
- SessionList: pass searchQuery to SessionItem
- SessionsStore: searchQuery/searchActive state, setSearch/clearSearch
- API layer: getSessions accepts search param
- MessageList: scroll to target message + brightness flash animation
- ChatStore: loadSession accepts targetMessageIndex, scrollToMessageIndex ref
- CSS: msg-flash keyframe animation in app.scss
- Tests updated for new getSessions signature

Compact and improve tool/thinking/plan card UX ...

- ToolCard: remove emoji header, collapse Arguments behind <details>,
  render results with structured JSON (color-coded values) or markdown
  detection for string outputs.
- SubagentStep: mirror ToolCard compact layout with same helpers.
- AssistantMessage: fold tool lists when >3 tools — show last 3 + summary
  bar with count and toggle icon-button; TransitionGroup for smooth
  expand/collapse animations.
- Plan card: switch accent color from info to secondary, compact sizing.
- Thinking card: compact sizing, remove bottom margin.
- app.scss: add details::details-content animation, fix nested chevron
  rotation in subagent steps, adjust margins and input-bar padding.

Markdown images: adaptive 3-column grid, lightbox modal, and broken-image handling ...

- useMarkdown.js: custom marked renderer wraps images in clickable links with
  inline onerror for broken-image detection
- app.scss: .msg-assistant-content becomes flex-wrap container; image paragraphs
  sized to 3-per-row via calc((100% - 16px) / 3); images are square via
  aspect-ratio: 1 / 1 and object-fit: cover
- ImageLightbox.vue: rewritten with proper gnexus-ui-kit .modal/.modal-dialog
  DOM structure; broken images show error placeholder inside modal
- AssistantMessage.vue: attachImageLightbox() wired after v-html render
- Broken images: .is-broken class prevents lightbox click; CSS shows 🖼️ icon

Persist uploaded files in messages, live file tree updates, and UI polish ...

Backend:
- Add `files` field to `Message` model so uploaded file metadata survives page refresh
- Pass `files` through websocket handler → `agent.run_stream` / `agent.run`
- `list_tools`: make `profile_id` required; return error instead of all-tools fallback

Webclient:
- Call `fetchFiles()` after successful file upload for immediate Files tab update
- Live refresh file tree on filesystem (write/edit/append/mkdir/rm/cp/mv), terminal, and code_exec tool calls
- Add manual refresh button (desktop) and pull-to-refresh (mobile) to Files tab
- Fix live link updates: move regex creation inside per-message loop to avoid lastIndex state leak
- Restore full profile name text next to avatar in ChatHeader; hide avatar in header
- Fix mobile ArtifactsPanel: collapse tab text labels so close button fits with 3 tabs

Add deterministic line-based file editing (edit_lines), rating UI fix, and session refresh ...

- filesystem.py: add edit_lines action (deterministic line ops via operations array)
           + numbered param for read (1-based line numbers in output)
           + clarify four editing modes in tool description
- chat.js: fix rating IDs for streaming messages (assign h_ ID on stream_end)
- SessionList.vue: mobile pull-to-refresh with PTR_THRESHOLD=80
- AppSidebar.vue: desktop refresh button next to Conversations header
- planning.py: knowledge source assessment in Phase 1
- debug panel: MCP servers tab + resolved tools per profile
- NAVI.md: reposition as neutral quick-reference
