This full reference config exercises every core section; the HTTP tuning blocks keep their defaults. Copy it, delete what you don't need, and fill in your values. The config in the Quickstart is a minimal version of this.

# Run with:
#   claude gateway --config gateway.yaml
#
# Operational log verbosity is controlled by the CLAUDE_GATEWAY_LOG_LEVEL
# environment variable (debug | info | warn | error; default info). debug
# also logs the claim names in each id_token, for groups_claim diagnosis.
# It does not affect audit events, which are always emitted.
