Night Sleep

name: night-sleep
description: The lamp falls asleep at night once nobody has been at the desk for fifteen minutes.

This core skill holds when the lamp sleeps at night. It has no model tool
and says nothing, lights nothing and plays nothing.

From 23:00 to 06:00, once no face has been seen, the voice has rested and
the lamp has been awake for fifteen minutes, it asks Expression for the
night's rest. Expression settles into its sleeping bow and slow breath, as
it always has. Its name heard with speech, a touch, a tap on the head, a
reminder coming due, a conversation, or the first face after 06:00 wakes
it, as before. Woken at night, it sleeps again after the same fifteen
minutes. A sound the voice only listens to does not wake it. With
`LAMP_REST_THROUGH_SOUNDS=on`, a sound heard as no words does not start the
fifteen minutes again either: only words, its name, a push, a touch
or the lamp speaking do. With the same switch in Expression, the voice
thinking at a line's end no longer wakes the sleeping lamp either: only
its own answer does, with a touch and a reminder. Its name stirs it, and
it settles back if no answer follows.

Turning this skill off is a choice that the lamp not sleep at night: it
still tells Expression that the night is its own, so Expression does not
sleep by itself either. The product turns its switches on; with no fresh
claim from it (lamp-skills down, an older skills folder, or a rest that
Expression keeps refusing for a reason that repeats), Expression's
built-in sleep keeps the night, a fallback for one release. See [Always alive](../../docs/alive.md#night-sleep-is-a-skill).
