Reasoning models (Qwen3-thinking via LM Studio, DeepSeek-R1, Kimi-K2,
etc.) can burn their entire output budget on hidden reasoning tokens and
emit no visible content. The previous title-generation retry path
classified that as llm_length and doubled the budget — but the second
call produces the same shape, so the retry only doubled the GPU/credit
burn. Repeated across the two prompts in _title_prompts() this came to
~3000 reasoning tokens of GPU work per new chat. On local LM Studio
servers behind a custom: provider (where is_lmstudio=False means
reasoning_effort: none never reaches the model) it manifested as the GPU
never going idle after a prompt.
Fix:
- _extract_title_response: classify reasoning-bearing empty responses
as llm_empty_reasoning regardless of finish_reason. The presence of
reasoning_content is the diagnostic signal, not finish_reason.
- _title_retry_status: drop llm_empty_reasoning from the retry set.
Length-truncated responses WITHOUT reasoning still retry (those are
legitimately recoverable by a larger budget).
- Add _title_should_skip_remaining_attempts() and break out of the
prompt-iteration loop on empty-reasoning. A second prompt against
the same model would produce the same shape.
- Falls through to _fallback_title_from_exchange for a local-summary
title.
Tests updated to invert the previous reasoning-retry assertions:
- test_aux_short_circuits_on_empty_reasoning_without_retrying
- test_aux_still_retries_finish_length_without_reasoning
- test_agent_route_short_circuits_on_empty_reasoning_without_retrying
- test_agent_route_still_retries_finish_length_without_reasoning
Companion agent-side work (LM Studio classifier for custom: providers)
is tracked separately on the hermes-agent side; this WebUI fix is the
belt-and-braces guard so the loop stops regardless of agent classifier
state.

(cherry picked from commit efeae4a86e377069c0f09d140429ecb111a8dd1a)
* fix: remove orphaned i18n keys from top-level LOCALES object
Three Traditional Chinese translation keys (cmd_status, memory_saved,
profile_delete_title) were placed outside any locale block between the
en and ru blocks in static/i18n.js. They became top-level properties
of the LOCALES object, causing them to appear as invalid language
options in the Settings > Preferences dropdown.
The correct translations already exist in the zh-Hant locale block.
Fixes#1008
* fix: block stale SSE events from polluting new session's DOM
- appendThinking(): guard with !S.session||!S.activeStreamId to drop
events from a previous session's SSE stream during a session switch
- appendLiveToolCard(): same guard for consistency
- finalizeThinkingCard(): scroll thinking-card-body to top when
scroll is pinned, so completed response is immediately visible
- appendThinking(): auto-scroll thinking card body to bottom while
streaming if user is watching (scroll pinned)
* Fix empty agent sessions in sidebar
* fix: resolve cron UI UX issues — icon ambiguity, toast overlap, running status
Fixes#995 — three sub-issues in the Cron Jobs UI:
1. Dual play icons ambiguous: Resume button now shows a distinct
play+bar icon (play triangle + vertical line) instead of the
identical triangle used by Run now.
2. Toast notification overlapping header buttons: Added
position:relative; z-index:10 to .main-view-header so it
stacks above the fixed toast (z-index:100 within its layer).
3. No running status after trigger: After triggering a job, the
status badge immediately shows 'running…' with a CSS spinner
animation, and polls the cron list every 3s (up to 30s) to
refresh when the job completes.
- Added cron_status_running i18n key in all 5 locales (en, es, de, ru, zh, zh-Hant)
- Added .detail-badge.running CSS class with spinner animation
- New functions: _setCronDetailStatus(), _startCronRunningPoll()
* fix(#1011): address review feedback — poll cleanup, badge persistence, 30s fallback
- _clearCronDetail() now clears _cronRunningPoll interval on navigation
- Poll re-applies 'running' badge after loadCrons() re-render (prevents flicker)
- When poll ends (30s max), detail re-renders with actual status as fallback
* feat: create folder and add space directly from UI (#782)
- After creating a folder via the file tree New folder button, offer to add it as a space via confirm dialog
- Add Create folder if it doesnt exist checkbox in the New Space form
- Backend: support create flag in /api/workspaces/add to mkdir before validation
- i18n: 4 new keys (folder_add_as_space_title/msg/btn, workspace_auto_create_folder) in all 6 locales
* fix: validate workspace path before mkdir to prevent orphan directories
Review feedback (critical): the previous code called mkdir() before
validate_workspace_to_add(), which meant a rejected path (e.g. system dir)
would leave an orphan directory on disk.
New flow:
1. Resolve path and check against blocked system roots BEFORE any mutation
2. mkdir() only if path passes the blocklist check
3. Full validation (exists, is_dir) after mkdir
Also imports _workspace_blocked_roots for the pre-mutation blocklist check.
* fix(#1014): classify model-not-found errors with helpful message
- Add model_not_found error type to streaming.py exception classifier
- Detect 404, 'not found', 'does not exist', 'invalid model' patterns
- Strip HTML tags from provider error messages (nginx 404 pages, etc.)
- Add model_not_found branch to apperror handler in messages.js
- Add i18n key model_not_found_label in all 6 locales
- 15 tests covering detection, sanitization, frontend, and i18n
* feat(ui): add live TPS stat to header
Adds a TPS (Tokens Per Second) chip to the right of the header title bar
that updates live while AI output is streaming.
Metering (api/metering.py)
- Tracks per-session output + reasoning tokens via GlobalMeter singleton
- Per-session TPS = total_tokens / elapsed_time
- Global TPS = average of active sessions' TPS values
- HIGH/LOW are max/min of global_tps snapshots over a 60-minute rolling
window (only recorded when > 0, so idle periods are excluded)
- Thread-safe with a single lock
Metering events emitted from streaming.py
- Throttled at 100ms from token/reasoning/tool callbacks so the display
updates rapidly during fast token streams
- 1Hz ticker as fallback for slow streams (exits when no active sessions)
- Final stats emitted on stream end
Routes (api/routes.py)
- Removed POST /api/metering/interval endpoint (dynamic interval via
focus/blur was replaced with simple always-1s-when-active approach)
UI (static/messages.js, index.html, style.css)
- TPS chip in titlebar: shows 'N.N t/s . N.N high . N.N low'
- Default: '0.0 t/s . 0.0 high' when idle
- Display updates on every metering SSE event (throttled to 100ms)
* feat: session restore speed + title gen reasoning hardening (#1025, #1026)
PR #1025 (@franksong2702): Speed up large session restore paths
- GET /api/session?messages=0 now parses only metadata before the messages array
- Metadata-only loads no longer populate the full-session LRU cache
- Frontend lazy fetch uses resolve_model=0 to avoid cold model-catalog lookup
- Hard reload no longer waits for populateModelDropdown() before restoring session
PR #1026 (@franksong2702): Harden auto title generation for reasoning models
- Raises title-gen completion budget to 512 tokens (reasoning-safe)
- Retries once with 1024 tokens on empty content / finish_reason:length
- Applies retry to both auxiliary and active-agent fallback routes
- Preserves underlying failure reason in title_status on local fallback

* feat: session attention indicators in right slot + last_message_at timestamps (#1024)
PR #1024 (@franksong2702): Polish session attention indicators
- Streaming spinners and unread dots now reuse the right-side actions slot
- Running/unread rows hide timestamps; idle/read rows keep right-aligned timestamps
- Date group carets point down when expanded, right when collapsed
- Pinned group no longer repeats pinned-star icon per row
- Running indicators appear immediately after send (local busy state while /api/sessions catches up)
- Sidebar sorting/grouping/timestamps now prefer last_message_at (derived from last real message)
so metadata-only saves don't make old sessions appear under Today

- _aux_title_configured(): returns True when provider/model/base_url is set
- _aux_title_timeout(): reads configured timeout, falls back to 15.0s default
- _generate_llm_session_title_via_aux: use_agent_model kwarg preserves old behavior
- Missing llm_invalid_aux fallback now triggers agent-model retry
- 23 new tests in tests/test_title_aux_routing.py — all pass
