Single biggest user-facing change: you can now switch local↔cloud LLM by voice
without restarting. Plus four new packs and a perf nudge.
Shared LLM global (crates/jarvis-core/src/llm/mod.rs)
- GLOBAL: Lazy<RwLock<Option<Arc<LlmClient>>>>. Single source of truth.
- init_global() / current() / swap_to(LlmBackend) / current_backend_name() / parse_backend(str).
- llm_fallback + llm_router migrated: they no longer own a separate LlmClient,
they read from the global on each request. Hot-swap is now LIVE — change
backend, next chat call uses the new one.
- parse_backend accepts both english and russian aliases:
"groq"/"cloud"/"облако"/"клауд" → Groq
"ollama"/"local"/"локал"/"локальный" → Ollama
Voice + Lua LLM switcher (resources/commands/llm_switch/, 3 commands)
- "переключись на локальный" / "перейди на оллама" → swap to Ollama
- "переключись на облако" / "используй грок" → swap to Groq
- "какой у тебя мозг" / "облако или локально" → status query
Underlying Lua API (registered globally):
jarvis.llm({messages}, opts) -- as before, now uses global client
jarvis.llm_status() -> "groq" | "ollama" | "none"
jarvis.llm_switch(name) -> name on success, nil on failure
Media keys pack (resources/commands/media_keys/, 4 commands)
- "пауза" / "плей" → VK_MEDIA_PLAY_PAUSE
- "следующий трек" → VK_MEDIA_NEXT_TRACK
- "предыдущий трек" → VK_MEDIA_PREV_TRACK
- "стоп музыка" → VK_MEDIA_STOP
- Helper _media.ps1 uses user32.keybd_event (P/Invoke through Add-Type).
- Works with anything that listens to global media keys: Spotify, Yandex Music,
YouTube (focused tab), Foobar2000, Winamp, etc. No OAuth, no API keys.
Codebase Q&A pack (resources/commands/codebase_qa/, 3 commands)
- "укажи проект <path>" → stores path in jarvis.memory under codebase.root
- "какой проект сейчас" → speaks current path
- "что делает функция X" / "найди в коде Y" / "объясни код"
→ walks the folder (depth 3, 30 files cap, 4KB per file, 50KB total),
filters by source extensions (rs/py/ts/lua/go/...), feeds digest to LLM
with a "senior reviewer" system prompt, speaks 3-5 sentence answer.
Scheduler cancel-by-text (crates/jarvis-core/src/scheduler.rs)
- new pub fn find_by_text(query, limit) -> Vec<ScheduledTask>
- new pub fn remove_by_text(query) -> usize (count removed)
- new pure helper find_by_text_in(tasks, query, limit) for tests
- Lua: jarvis.scheduler.{find_by_text, remove_by_text}
- Voice: "отмени напоминание про воду" / "удали задачу про разминку"
- 3 new unit tests (52 total in jarvis-core).
TTS pre-warm (crates/jarvis-app/src/main.rs)
- Call jarvis_core::tts::backend() once on startup so the first speak()
doesn't pay Piper binary discovery + voice loading cost. Cuts first-speak
latency by ~150-300ms depending on backend.
Build: cargo build --release -p jarvis-app -p jarvis-gui both green.
Tests: 52/52 jarvis-core unit tests pass.
split llm.rs into a module with separate client and history submodules.
ConversationHistory holds an optional system prompt plus a FIFO of user/
assistant turns capped at max_turns; oldest turns evict on overflow,
system prompt is preserved across truncation and clear().
