Functions exposed to the LLM to take actions

Name	Description
profile_getA	Read the full user profile (name, speech_id, birthday, profession, expertise, durable traits, ...). Describes the user's durable state.
profile_setA	Set one profile field. `value` is parsed as JSON when possible (lists/numbers/null), otherwise stored as plain string. value="null" deletes the field. Returns the updated profile.
sensor_readB	Read a virtual sensor (e.g. "stress", "room_intensity"): smoothed value, last raw observation, last update time.
sensor_reportA	Report a raw observation (0-100) for a virtual sensor. The stored value follows it smoothly (time-aware exponential smoothing; the tau_seconds reactiveness per sensor is set in config.json). Returns the new smoothed state. Use name="stress" for the user's stress level and name="room_intensity" for the room's current intensity.
state_getA	Read the full live state: all virtual sensors plus the curve that combines both axes (target room intensity for the current stress level, and the delta between actual and target).
