quiet-hours

name	quiet-hours
description	Night-time noise cap — low TTS volume, skip broadcast fan-outs, pause alerts until morning.

Quiet Hours

Trigger on "quiet hours", "sleep-friendly mode", "静かにして" at night, or any phrase that suggests the household is asleep / has a sleeping infant.

Distinct from goodnight (one-time bedtime routine) and bedtime-routine (wind-down): quiet-hours is a stateful mode that persists until the user says "quiet hours off".

Default flow on activation

1. Volume: set_volume to 10. Any TTS from here stays whisper-low.
2. Announce to self: speak a quiet "Quiet hours on. I'll keep it down." — confirmation at the new volume is itself a test.
3. No multi-room fan-out — do NOT call broadcast_tts / broadcast_timer / broadcast_announcement while quiet-hours is active. Other speakers might be in rooms where the baby is sleeping. If the user explicitly asks for a broadcast, confirm: "Quiet hours is on — broadcast anyway?"
4. Skip proactive suggestions — don't spontaneously offer morning briefings / reminders.
5. Lights: don't force lights off — the user may have already set the scene. Only dim brighter-than-40 % lights to 40 %.

While quiet-hours is active

• All responses keep TTS short. One sentence max.
• Timers still fire at their original volume (system audio, not TTS — we can't silence the Android alarm channel without the user's Do Not Disturb settings).
• If the user asks the agent something ambiguous, prefer a fast-path answer over an LLM round-trip to save the fan noise from model inference.

End-of-session

Trigger on "quiet hours off", "morning now", "静かモード終わり":

1. Restore volume to 50.
2. Speak: "Good morning."
3. If multi-room is on, do not fan out "good morning" — let each speaker greet when its own human wakes up.

Style

• Tone: gentle, not cheerful. This is the middle-of-the-night mode.
• Japanese: always formal-polite. Matches night-time register.
