feat(brain): route real-time search by live broadcast state
STREAM_BROWSER becomes the broadcast *capability* master flag; the live screen-share state (new ToolContext.broadcasting, passed per turn by the bot) decides the backend: - master off -> broadcast disabled, always Gemini - master on + live on -> on-screen Chrome (visible on the stream) - master on + live off -> Gemini context.broadcasting is None outside the voice path (evals, text entry, older bot) and falls back to the master flag, so current behaviour is unchanged. This is the brain-side foundation; bot-side wiring (bridge passes broadcast state, auto-broadcast on voice join, voice on/off toggle) follows. Specs + docs/llm_contexts.md updated. Covered by tests/test_web_search_broadcast_routing.py. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

### Real-time info routing (`STREAM_BROWSER`)
|
||||
|
||||
Before the DuckDuckGo cascade, `run()` routes by the env flag `STREAM_BROWSER`
|
||||
(mirrored into `cfg.stream_browser`; see `docs/stream_browser_modes.md` and
|
||||
`realtime_search.py`):
|
||||
Before the DuckDuckGo cascade, `run()` routes by the broadcast capability flag
|
||||
`cfg.stream_browser` (env `STREAM_BROWSER`) combined with the live broadcast
|
||||
state `context.broadcasting` for the turn (see `docs/stream_browser_modes.md`
|
||||
and `realtime_search.py`). `context.broadcasting` is `None` outside the voice
|
||||
path (evals, text entry) and falls back to the master flag:
|
||||
|
||||
- **true** (default): `browser_search()` drives the on-screen Chrome (Node CDP
|
||||
helper `bot/scripts/stream-test/browse-search.mjs`) to Google-search the
|
||||
query, so the action is visible on the Go-Live broadcast.
|
||||
- **false**: Gemini answers, with the sub-mode chosen by `cfg.gemini_auth`
|
||||
| `cfg.stream_browser` | `context.broadcasting` | backend |
|
||||
|---|---|---|
|
||||
| True | True | on-screen Chrome (`browser_search()`) |
|
||||
| True | False | Gemini |
|
||||
| True | None | Chrome (no signal -> master flag) |
|
||||
| False | any | Gemini (broadcast disabled, never Chrome) |
|
||||
|
||||
- **on-screen Chrome**: `browser_search()` drives Chrome (Node CDP helper
|
||||
`bot/scripts/stream-test/browse-search.mjs`) to Google-search the query, so
|
||||
the action is visible on the Go-Live broadcast.
|
||||
- **Gemini**: answers, with the sub-mode chosen by `cfg.gemini_auth`
|
||||
(env `GEMINI_AUTH`, default `oauth`):
|
||||
- `oauth` (default): `gemini_cli_search()` shells out to the Gemini CLI
|
||||
(`gemini -p <query> -o json --skip-trust`, default approval mode) using the
