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: artifacts panel — compact actions, refresh in static row, file icons via phosphor 2.x ...

- artifact-actions: flex wrap gap 4px instead of full-width stretched grid
- files refresh: static toolbar row (GnIconButton sm) instead of floating
  absolute button that sat on top of the first list rows
- file icons: phosphor vendored 1.4.2 lacked the file-type glyphs
  (py/ts/js/html/css...) that fileIcon() already mapped — upgrade to
  @phosphor-icons/web 2.1.2 (bundled regular font), drop the vendor dir;
  json -> file-code (phosphor has no json glyph)

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: artifacts panel -> kit 1.0 visible pass ...

Tabs became kit chips (aria-pressed selected state, plain count inside),
empty states became GnEmptyState, action/refresh/close icon buttons moved
to kit btn-icon / GnIconButton, list badges to kit .badge variants. List
rows dropped the filled-box look for the kit idiom: subtle hover fill and
a left accent bar with panel-muted fill for the selected row. Header is
now stretchable so wrapped chips don't clip. Raw hexes and font literals
replaced with --gn-* tokens.

webclient: center lightbox photo in the modal panel ...

Kit's .modal .modal-dialog .modal-panel min-height rule (0,3,0) beat the
lightbox's own override, so shorter photos sat at the top of an empty
panel and the dialog hugged them horizontally. Drop the shrink-wrap, let
the dialog keep the standard kit width and center the image in the panel
body both ways.

webclient: replace vue-virtual-scroller with plain content-visibility rendering ...

The virtual scroller's measurement states duplicated item views (parked
copies at translateY(-9999) alongside working ones), which made tool/plan/
thinking cards unclickable and the chat flicker. Both chat messages and
the session sidebar are now plain v-for lists; off-screen rows skip
render/paint via content-visibility: auto, keeping long sessions cheap
without the scroller engine. Library removed from dependencies.

webclient: reconnect banner -> GnAlert (kit warning styling)

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: product dist rebuilt on kit 1.0 (tracked, served by backend)

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: merge Terminals into Backgrounds tab (single list) ...

One list of background tasks and terminals, running first. Row icon and
badge distinguish kind; details route to task or terminal card. Selection
resets on session switch and drops dangling entries when the selected
task/terminal disappears.

webclient: Backgrounds tab in artifacts panel + task toasts ...

- new Backgrounds tab: task list (running first, badges, per-tool icons)
  with a detail view (status, timestamps, sub-agent tokens, result/progress)
- GET /sessions/{id}/tasks snapshot endpoint: task_update events are not
  replayed on reconnect, so the client fetches the task list on session
  load/reload; live task_update entries are merged on top (chat.fetchTasks)
- terminal task_update no longer removes the entry — it marks it finished
  so the tab shows recent completions; _terminalTaskIds still blocks
  resurrection by a late running update
- toasts for background task start / finish (info / success / error) in
  the WS dispatch; silent for other sessions and unknown terminal ids
- persistent background-tasks chip removed (replaced by the tab); only
  the queued-messages chip stays
- fix invisible status text in terminal detail rows: filled .status-*
  backgrounds now scope to .terminal-status-badge only

background tasks: review fixes B1-B11 batch ...

- stop mid-batch cancels in-flight tools (B1) and keeps real results
  of already-finished ones, mixing them with synthetic stopped notes
  in call order (B2)
- queued messages: headless drain publishes session_sync (B4), the
  run's teardown broadcasts session_sync to other sockets but not the
  owner socket (prevents double reload) (B5)
- task_update notifications are chained per task so late running
  updates can't overtake the terminal one (B7; client drops late
  re-flicker of a terminal task chip) (B8)
- client: ui_component results reference the owning message via
  card.parentMsg instead of a stale msg reference (B6)
- tasks cancel reports the real outcome after a bounded wait instead
  of an optimistic 'cancelled' (B9)
- session delete cancels its running background jobs and drops
  pending result notes (B10)
- subagent tool loop routes background:true calls through
  ToolExecutor._maybe_background like the main loop (B11)
- tests for all of the above; docs/tasks.md stop/cancel semantics

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: 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.

chat history pagination: paged load instead of full-session fetch ...

Backend:
- PgSessionStore.get_meta — light session head (sessions row + COUNT),
  no message payload
- PgSessionStore.get_history_page — page of display history (archive ∪
  hot UNION), newest-first page, oldest-first result, limit+1 peek for
  has_more; each message stamped metadata.display_index (ROW_NUMBER-1
  over the full display history) so client ids stay stable across
  paged loads; dangling-tool-call repair keeps real ranks by
  sequence-number lookup
- GET /sessions/{id}/meta and GET /sessions/{id}/messages/history
  (before_seq cursor, limit ≤200)

Webclient:
- loadSession/reloadSession fetch meta + newest 200-item page
  (Promise.all), archive state from the page itself
- buildMessageList ids (h_*) and rawIndices use the global
  display_index — feedback keys and search-jump stay stable when
  history is paged
- scroll-up loads older pages through the same history endpoint
  (archive table alone misses sessions whose threshold never moved)
- search-jump pulls pages until the target index is covered (bounded)

Tests: store unit tests (ranks, has_more peek, placeholder shift) +
vitest updates; full pytest 1231 passed, vitest 94 passed.

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: lightbox dialog shrink-wraps the photo, img without crop

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

PWA: installable webclient, offline shell, web push ...

Installability:
- public/manifest.webmanifest (standalone, theme #16161E) + PNG icons
  generated from logo.svg (regular + maskable, served via /images mount)
- index.html: manifest link, theme-color, apple-touch-icon

Offline shell:
- hand-rolled sw.js (no workbox): navigation = network-first (3s race)
  with cached-shell fallback + background refresh (a stale cached shell
  would 404 on entry chunks after a deploy); /assets/* cache-first
  (content-hashed); /images/* cache-first capped; /api,/ws,/auth,/push,
  /content pass-through
- vite closeBundle plugin stamps __NAVI_BUILD_VERSION__ (digest of
  index.html + asset names) into dist/sw.js; sw.js served no-store so
  every deploy reactivates the SW and activation evicts old caches
- SW registration in main.js, PROD only (dev HMR untouched)
- OfflineBanner (useOnline composable) over the app shell

Web push (VAPID, pywebpush):
- navi/push/ package: push_subscriptions table (postgres, boot-time DDL),
  PushSubscriptionStore, PushService (async fan-out, to_thread sends,
  404/410 prunes dead endpoints, per-session cooldown)
- routes: GET /push/vapid-key, POST/DELETE /push/subscribe (auth-gated)
- trigger in orchestrator run_agent + run_recall: push on StreamEnd when
  no WebSocket client watches the session; fire-and-forget, never
  disturbs the run; anonymous fallback only when auth is off
- client: usePush composable + Notifications settings panel (enable/
  disable via PushManager.subscribe with the server VAPID key)
- notification click focuses the app at /#<session_id> (hash routing
  opens the right chat); payload body is a markdown-stripped <=140-char
  preview

NAVIVAPID keys empty = push fully disabled (graceful, like other optional
integrations). dist/ artifacts committed per repo convention.

Tests: pytest push store/service/routes/trigger (+23), vitest usePush
(83 webclient tests green). Full suite 1143 passed.

webclient: rebuild dist from merged source (navi_ui + XSS fixes); keep dist tracked

feat: integrate navi_ui MCP server (card_grid + form) into master ...

Port the internal navi_ui MCP server from the vmkdemo branch (it never
landed on master). The server exposes render_component, which returns a
structured JSON envelope; navi/mcp/tools.py extracts metadata.ui_component
onto the role="tool" message, and the webclient renders the component
(card_grid, form) inline inside the assistant turn.

Backend
- navi/mcp/ui_server/: FastMCP server + component registry with card_grid
  and form components (pydantic-validated payloads, LLM-friendly schema docs)
- mcp_servers.d/navi_ui.json: streamable_http config, group "ui"
- config.py: navi_ui_mcp_enabled/host/port flags
- main.py: start UI server in lifespan (task + wait-for-ready + cancel)
- mcp/tools.py: navi_ui envelope parsing; "Error:" results surface as
  failed tool calls so the UI card is not green
- orchestrator.py + agent.py: run_stream(hidden=) for form submissions
  (single is_display=False, is_context=True user message)
- api/websocket.py: extract _start_agent_run helper, add form_submit
  branch that delivers submitted form values as a hidden user message
- profiles/secretary: enable navi_ui "ui" group (agent + subagent)
- .env.example: NAVI_UI_MCP_* flags
- tests/unit/mcp/test_ui_server.py

Webclient
- components/ui/{registry.js,CardGrid.vue,Form.vue}: auto-discovered
  renderers (snake_case <-> PascalCase aliasing)
- components/messages/UiComponentCard.vue: wrapper rendered in
  AssistantMessage when entry.kind === 'ui_component'
- stores/chat.js: extract ui_component from tool_call metadata in both
  live stream and history-replay paths
- composables/useWebSocket.js: note that ui_component rides tool_call
- tests/unit/components/ui/* (17 tests)
- dist rebuilt

Excluded from the vmkdemo port: the stale single-file navi/mcp/ui_server.py
duplicate, the realtor profile, and the vmk_data server (unrelated real
estate work that was interleaved with navi_ui on vmkdemo).

Fix terminal detail UX: description wrapping, status contrast, close button ...

- Remove `white-space: nowrap` from `.terminal-detail-meta` and
  `.terminal-item .artifact-meta` — long descriptions now wrap instead
  of being clipped with ellipsis.
- Add `-webkit-line-clamp: 2` to list-item meta so description is
  limited to 2 lines with graceful overflow.
- Fix status colour in detail rows: `.terminal-detail-value.status-busy`
  etc. added after `.terminal-detail-value` so their colours override
  the default #C0CAF5 (was causing light-on-light text).
- Add close button (X) inside `.terminal-detail-header` to dismiss
  the detail pane without leaving the tab.
- Make `selectTerminal` toggle: second click on the same item deselects.
- Build webclient and run tests — all pass.

Fix reloadSession race that orphans streamingMsg ...

reloadSession checked streaming.value at entry but api.getSession is
async. While awaiting, onStreamStart could set streaming=true and push
the assistant message into messages.value. When reloadSession resumed it
replaced messages.value with the stale server snapshot, evicting the live
streaming message. All subsequent deltas and tool cards went to the orphan
and were invisible.

Fix: re-check streaming.value after the await before mutating messages.

Fix delta loss during thinking-to-text transition and streaming orphaning ...

Backend:
- agent.py _consume_stream: replace elif with if so a single chunk can
  carry both the final thinking fragment AND the first text delta.
  Fixes the 'first token lost after tools' bug.

Frontend:
- chat.js reloadSession: bail out early when streaming.value is true.
  Replacing messages.value mid-stream orphans streamingMsg, breaking
  Vue reactivity for all subsequent deltas and tool cards.
- useWebSocket.js session_sync handler: add !chat.streaming guard
  before calling reloadSession.
