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: W5 — icon/variant audit + design-system docs in CLAUDE.md ...

- ApiKeysPanel: dropped invalid variant="ghost" on GnIconButton (the
  component has no variant prop — it leaked into the DOM as an attribute)
- Icon audit: all icon props/classes carry the required ph base class
  and ph- prefix (kit v1.0 dev-warning otherwise); variant whitelist
  (primary/secondary/warning/danger/info) confirmed against the kit
- webclient/CLAUDE.md: new 'Design system (gnexus-ui-kit v1.0)' section
  — points to vendor/gnexus-ui-kit/CLAUDE.md, documents prebuilt-css
  consumption, dark kit.css theme, --gn-* + kit-deps tokens, icon rule,
  test-locked app classes, and the documented non-kit surfaces

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

compressor: single-summary invariant — old summaries always fold into the fresh one ...

partition_messages now strips is_summary messages out of the turn structure
before grouping: a summary is already-compressed history, not a user request.
Previously its role=user made it a turn head, so midturn compression kept the
old summary verbatim beside the fresh one (head kept + new summary added),
and adaptive swap resurrected summary turns whose text pattern-matches the
importance heuristics. This piled stale summary copies into the context
(one session accumulated 6 copies = 120k of 239k chars) and made compression
no-op for whole stretches before a lucky pass finally shrank it.

Also folds summaries on the early-exit path so two stale summaries
consolidate via the meta-summary, and fixes the demotion loop in
compress_and_save_session to cover session.context too: after a reload,
context-only rows (is_display=False summaries) were absent from
session.messages and never demoted, so is_context=True persisted in the DB
and the copies survived into the loaded context.

webclient: perf dev config (vite override proxying to an isolated server on 8097)

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: 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: fix session-list flicker and double-load on select ...

- fetchSessions merges into existing items (preserve object references)
  instead of wholesale array replacement — DynamicScroller reuses rows,
  the list no longer repaints/reflows on every refetch (measured: sidebar
  repaint spikes 8-17% per switch -> 0)
- AppSidebar.handleSelect no longer refetches the list on a plain select;
  refetch only when leaving search (the array still held search results)
- loadSession now lives only in handleSelect — SessionList.onSelect used
  to start a first load and handleSelect raced it with a second one
  (double fetch + double buildMessageList, incl. search-jump target)
- pinSession mutates in place instead of replacing every item object
- SessionItem.highlightText matches on the raw string so <mark> offsets
  stay correct when the text contains &/</>

local mode isolation: anonymous user is a NULL-owner user, not an alias ...

Local mode (NAVI_AUTH_ENABLED=false) used an anonymous admin whose admin
role widened every session listing to ALL users' chats — acceptable only
while assuming a private database, but a real leak on any shared one.

- session listings (list_all/list_page/count_all/search_list): new
  scoping rule — non-admin with user_id=None sees only user_id IS NULL
  rows; named owner unchanged; admin unchanged
- session create/list routes: owner id is None in local mode (sessions
  are persisted ownerless), admin listing flag resolved only when auth
  is enabled
- check_session_access: local mode allows only NULL-owner sessions —
  a user-owned session by id is 403
- debug/admin endpoints (require_admin) stay reachable in local mode
- prod DB: 30 stray user_id='anonymous' rows reassigned to NULL owner

Tests: store scoping unit tests, local-mode integration tests (sidebar
filtering + access by id), updated check_session_access unit tests.
Full pytest 1239 passed, 1 skipped.

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.

Merge remote-tracking branch 'origin/master'

context: task-note messages survive build()'s system filter ...

E2E caught a real delivery bug: the completion note was drained and
persisted (agent.task_notes_drained logged) but build() filtered out all
system-role history from session.context, so the LLM never saw it — the
agent could only get detached results via tasks check. Notes now carry
metadata source=task_note (kept by build) and is_display=False (clients
already show live task_update events). Verified live: agent reads the
note verbatim without calling any tool.

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

container: runtime-import PushService — master could not boot since the PWA commit ...

PushService was only imported under TYPE_CHECKING; create_container raised
NameError at startup. Caught by the first real boot (e2e) — the running
production container predates the PWA commit, so master was silently
un-launchable.

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

agent parallelism: background tools, bg spawn_agent, parallel tool batches, message queue ...

- backgroundable tools (terminal/ssh_exec/peer/spawn_agent/code_exec) detach
  via TaskManager with per-session/global/spawn caps, rate limit and TTL
- completion delivery both ways: task_update event (out-of-band) + pending
  notes injected into the next turn; tasks tool (list/check/wait/cancel)
- parallel tool-call batches (profile-level gate, off by default) with
  ToolStarted up-front, tagged event mux, call-order results, one save,
  plus dangling tool_call repair on session load
- user message queue instead of busy error: message_queued frame,
  back-to-back drain on the same socket, headless fallback on disconnect
- pin mcp<2 (v2 renames FastMCP with breaking API changes)
- docs: tasks.md (new), websocket/api/agent/config updates, tasks manual,
  spawn_agent background param, persona contract section

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.

planning: fix LLM-output failure modes that killed every plan ...

Production planning_logs showed three ways a plan silently dies:

1. glm-5.3-flash wraps the whole answer in a structured envelope
   (response:unknown{value:...}<tool_call|>) — the planner only knew the
   gemma4 thought<channel|> artifact, so the wrapped analysis/plan failed
   to parse. The stripper now unwraps response:<type>{value:...} envelopes,
   including a truncated (unbalanced) one.
2. Empty content with spent completion tokens: glm on ollama-cloud puts
   the whole answer in the thinking channel on some calls. Both planning
   phases now fall back to thinking when content is empty; the debug log
   records which channel served (source: content|thinking).
3. phase3_timeout at the shared 120s LLM_COMPLETE_TIMEOUT: planning now
   has its own PLANNING_LLM_TIMEOUT_SEC (default 240).

Unit tests cover the envelope unwrap (balanced/truncated/inner braces),
the thinking fallback in both phases, and the clean-fail path.

deploy: NAVI_HOST=0.0.0.0 — fresh installs join the swarm peer channel ...

Fresh deployments were 'visible but deaf': announcements to the hive are
outbound and worked, but inbound /peer/* connections hit the localhost-only
bind and failed with ConnectError. 0.0.0.0 makes the peer channel work;
127.0.0.1 stays documented for machines outside the swarm.
