test: settings output_language survives save→apply→recreate

Integration test driving the real bridge _save() and engine
_resolve_output_language(): a language chosen in the settings UI is written to
both the persistent volume and the runtime config, applies immediately (config
wins over the OUTPUT_LANGUAGE env), and survives a simulated container recreate
(entrypoint re-renders the config then merges the persistent override). Also
asserts the persona and reply directive both follow the persisted language.

+
+One image, three roles (`JARVIS_ROLE`), selected in `.env`. GPU is added per OS
+via a compose override picked with `COMPOSE_FILE`.
+
+## A. All-in-one (single machine)
+
+Everything (desktop + Chrome + bridge + bot + TTS) in one container.
+
+```
+# .env
+JARVIS_ROLE=full
+COMPOSE_FILE=docker-compose.yml:docker-compose.gpu-linux.yml      # Ubuntu
+# COMPOSE_FILE=docker-compose.yml:docker-compose.gpu-windows.yml  # Windows 11
+DISCORD_SELFBOT_TOKEN=...
+DISCORD_GUILD_ID=...
+
+docker compose up -d            # Ollama + javis (COMPOSE_FILE adds GPU)
+```
+
+## B. Split: browser host (LAN) + bot on your PC
+
+The on-screen Chrome, real mouse/keyboard (xdotool) and screen live on the
+**browser host**. Your PC runs the **bot** and drives that browser over the
+internal network — no auth (internal only).
+
+### Browser host (the LAN machine that shows Chrome, e.g. 192.168.10.9)
+
+```
+# .env
+JARVIS_ROLE=browser
+CDP_BIND=0.0.0.0
+BROWSER_CONTROL_BIND=0.0.0.0
+CDP_PUBLISH_BIND=0.0.0.0
+# no GPU needed → leave COMPOSE_FILE unset (base compose only)
+
+docker compose up -d javis      # desktop + Chrome + control-server (port 8777)
+```
+
+Watch it on this machine’s VNC (`localhost:5901`) / noVNC (`localhost:6080`).
+
+### Bot host (your PC — Ubuntu or Windows 11)
+
+```
+# .env
+JARVIS_ROLE=bot
+BROWSER_CONTROL_URL=http://192.168.10.9:8777      # the browser host's LAN IP
+COMPOSE_FILE=docker-compose.yml:docker-compose.gpu-linux.yml      # Ubuntu
+# COMPOSE_FILE=docker-compose.yml:docker-compose.gpu-windows.yml  # Windows 11
+DISCORD_SELFBOT_TOKEN=...
+DISCORD_GUILD_ID=...
+
+docker compose up -d            # bot + bridge + TTS + Ollama (GPU per OS)
+```
+
+The bot’s `controlBrowser` tool posts commands to `BROWSER_CONTROL_URL`, so
+"네이버에서 X 검색", "구글로 돌아가" etc. drive the **browser host’s** Chrome with real
+human-style input (visible on its VNC).
+
+## Windows 11 notes
+
+- Install the NVIDIA driver on Windows and enable GPU in Docker Desktop
+  (Settings → Resources → WSL Integration). Use the `gpu-windows.yml` override.
+- Paths: named volumes are cross-platform. The Gemini OAuth bind mount defaults
+  to `${HOME}/.config/javis/gemini` (works under WSL); override `GEMINI_OAUTH_DIR`
+  if needed.
+
+## Known limitation
+
+Discord Go-Live broadcast of the **browser host's** screen from a **remote** bot
+is not supported (the bot's WebRTC screen capture is local to the bot machine).
+Use the browser host's VNC to view it. A full remote-broadcast path is separate,
+larger work.

+  - Unified system prompt from [src/jarvis/system_prompt.py](src/jarvis/system_prompt.py) + ASR note + tool-protocol guidance. Reply language is resolved by `reply_language_directive(lang, cfg.tts_engine)` where `lang = _resolve_output_language()` — the single source of truth that prefers the settings-web UI value (config JSON `output_language`) over the compose `OUTPUT_LANGUAGE` env, so changing the language in the settings page takes effect. An explicit lock wins (forces "reply only in `<language>`", also forbidding other scripts so small models stop leaking trailing CJK/Hanja); else a Piper/Chatterbox TTS forces English (English-only voices); else (multilingual TTS, no lock) the assistant replies in the user's own language. The directive is inserted near the FRONT of the guidance list so a small model gives it primacy, and the SAME resolved `lang` feeds `build_system_prompt()`, which rewrites the persona's "in the user's language" clause to the locked language so the persona cannot contradict the directive (previously the persona read the raw env while the directive read the config value, so a settings-UI change was honoured by one and ignored by the other). Gated in `_build_initial_system_message()` at [engine.py](src/jarvis/reply/engine.py).
   - **Warm profile block** (query-agnostic User + Directives excerpt from the knowledge graph, composed by `build_warm_profile()` / `format_warm_profile_block()` in [src/jarvis/memory/graph_ops.py](src/jarvis/memory/graph_ops.py) at Step 3.5 of `reply()`; no LLM call, pure SQLite read; injected unconditionally so personalisation is the default; result cached in `DialogueMemory._hot_cache` under `DialogueMemory.WARM_PROFILE_CACHE_KEY` for the lifetime of the active conversation. Invalidated on `stop`, on new-conversation entry, AND on User/Directives graph mutations via the listener registered in [src/jarvis/daemon.py](src/jarvis/daemon.py) against `register_graph_mutation_listener` in [src/jarvis/memory/graph.py](src/jarvis/memory/graph.py); World-branch writes are ignored)

+"""End-to-end persistence of the output_language settings change.
+
+Closes the loop the reviewer flagged: a language chosen in the settings web UI
+must (1) take effect immediately for the reply engine and (2) survive a
+container recreate. The pieces:
+
+  bridge._save()        -> writes BOTH /data/jarvis-settings.json (persistent)
+                           and JARVIS_CONFIG_PATH (live runtime config)
+  entrypoint merge      -> on recreate, re-renders config from the env template
+                           then merges the persistent overrides back on top
+  engine._resolve_output_language() -> reads JARVIS_CONFIG_PATH, config wins
+                           over the OUTPUT_LANGUAGE env
+
+This test drives the REAL bridge save function and the REAL engine resolver
+(the resolver is loaded standalone because the full engine import needs the
+mcp package, which isn't installed in CI here). It simulates the env default
+disagreeing with the chosen language, which is exactly the bug condition.
