# Halkyon Meditate's server beside the instance (ADR 0038, step 7; ADR 0039, D14).
# Switched on in .env, with Meditate's domain and secrets:
#
#   COMPOSE_FILE=compose.learn.yaml:compose.meditate.yaml
#   MEDITATE_DOMAIN=meditate.halkyon.li
#
# Meditate is a member of the instance's register, which Learn's server holds (ADR
# 0016), as Todo is: one account a person, signing in through the register, the shared
# INSTANCE_SECRET on every call between them, which reach each other on the instance's
# own networks alone. Its database is `halkyon_meditate` in the instance's PostgreSQL,
# under a role of its own that can't connect to the other apps'. Its server reads no
# sitting and no dream: every row is sealed on the person's devices (ADR 0038, D7). The
# operator's library (D16) is a file of its own, compose.meditate-library.yaml; without
# it Meditate has none. Setting it up: sidecars/README.md, Meditate.
