`llm.json` replaces `OLLAMA_BACKENDS_FILE`. It has targets (host and key
environment variable) and routes, where a route is an ordered chain of
`model @ target` entries, each with its own `context_window` and options. The
`default` route now starts on `glm-5.3-flash:cloud` and backs it with
`qwen3.6:35b-128k` on the home host, both at 131072 tokens, so a failover no
longer changes the budget the compressor and `num_ctx` are accounted against.
Embeddings get their own `embedding` route instead of a pinned host.

The engine classifies a failure (network, quota, auth, server, missing model),
cools that entry and moves the call down the chain; a background probe watches
only degraded targets and lets the next turn return to the primary once it is
healthy — it never interrupts a running turn. A profile joins a route with
`llm_route`, and the loader now actually reads it: `llm_route` and
`context_window` were declared on `AgentProfile` and written into every
`config.json` while the loader skipped both, the same silent no-op that
`is_admin_only` used to be, so every profile ran the legacy model list at the
global window. The writer emits them too, or an admin edit would erase the
route from disk.

The turn's resolved entry travels to the UI: the first chunk is stamped with
model and target, `model_info` carries `fallback` when a backup answered, and
the chat header shows a chip only then. `serving_primary` compares the target
as well as the model name, because a route may run one model on two hosts.
`/health` gains an `llm` block with the active entry, target states and missing
models.

`deploy/ollama/` keeps the local model's definition honest: MTP off (slower at
every context on this host), `presence_penalty 0` (the base model's 1.5 breaks
agentic tool calls), and `num_gpu 40` — Ollama's automatic fit claims a 128k
f16 slot fits and then dies mid-prefill with CUDA OOM; 40 of 42 layers leaves
~400 MiB and decodes at ~77 tok/s, 38 layers collapses to 48, and 39 OOMs.
q8_0 KV measured 37 tok/s against 70 on f16 here, so the cache stays f16.

The fifth area of the interface translation. The chat screen now builds its
text through t(): the header (the rename tooltip, the sidebar toggle, the
artifacts toggle, and the recall banner with its Cancel and Skip next
buttons), the list around it (the connection-lost banner and its Retry, and —
unreachable for now — the empty state), the input bar (the sending notice, the
paperclip, the placeholder, Send and Stop generation), the attachment strip
(its alt text and its remove button), the message list (Loading older
messages… and the scroll-to-bottom tooltip) and the queued-messages chip. Also
four toasts the WebSocket composable raises — background task started /
finished, MCP server connected / disconnected — and the compression notice's
own pending text.

26 new slugs in all three dictionaries:

- 20 in chat.* — the header and recall banner, the input bar, the attachment
  strip, the queued chip and the empty state;
- 4 in toast.* — the two background-task and the two MCP toasts;
- 2 in common.* — task and toolsCount.

Four details worth knowing:

- The recall banner used to read the server's call_type enum out loud
  ("Scheduled once recall at …"). The word is now a slug
  (chat.recallOnce / chat.recallRecurring / chat.recallImmediate), so it agrees
  with the sentence around it — Russian and Ukrainian both change the
  adjective's gender and the preposition, which a bare enum cannot.
- The banner's time was formatted with the browser's locale; it now formats
  against locale.value, so the date follows the interface language rather than
  the machine.
- The queued chip counted with `count === 1 ? '' : 's'`. It is now a dictionary
  plural driven by {n}, which is what Russian and Ukrainian need — "1
  сообщение", "2 сообщения", "5 сообщений".
- toolsCount moved from messages.* to common.*: the tool-count badge in the
  assistant message and the MCP-connected toast both render it, so the same
  word lives in the vocabulary area instead of twice under two areas.
  docs/i18n.md records the move.

The English values are verbatim the literals the code hard-coded, so the
English interface is unchanged and no test needed editing.

Checked live in Chromium against the built bundle on the dev backend, all
three languages: the header title, the input placeholder, both input-row
buttons, the recall banner and its buttons, twelve message rows and the
attachment's alt and remove — read fresh for each language by picking it in
Settings first — with a scan of the page's text, titles, aria-labels, alt texts
and placeholders for a slug that leaked into the interface as the pass
condition.

Two states a saved session cannot be put into are covered by a throwaway mount
instead, and the file was removed again: the streaming input bar (Sending…,
Stop generation) and the queued chip, plus the recall words and the toast
titles, printed in Russian — "1 сообщение в очереди" / "2 сообщения" /
"5 сообщений".

The connection-lost banner never appears in this harness: with no socket token
the server refuses the socket and the client never exhausts its retries inside
the test's window, on the current build and on HEAD's alike. It is covered by
the existing tests/unit/composables/useWebSocket.test.js and by reading
ChatArea.vue; the same goes for chat.nothingOpen / chat.startConversation,
which App.vue's WelcomeScreen shadows before ChatArea can render its own empty
state — the branch is dead today and keeps its slugs for when it is not.

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

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

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

gnexus-ui-kit's iconNode() does not prepend the base `ph` class
when the icon string starts with `ph-`; it only keeps the string
as-is. All icon props must include the base class explicitly:
`icon="ph ph-sidebar"` instead of `icon="ph-sidebar"`.

Updated 15 icon bindings across 9 components.
