# Test stack Corefile -- isolated from the production Corefile by virtue
# of running in a separate docker-compose project on different ports.
#
# Plugin chain semantics:
# - auto loads test.example.com.zone from /zones; reload every 5s
# so we see UPDATE-induced changes promptly during smoke tests
# - rfc2136 intercepts UPDATE opcode; passes all queries through to auto
#
# Plugin.cfg order (set in coredns/Dockerfile) puts rfc2136 BEFORE auto AND
# BEFORE cache, so UPDATE messages reach our handler before anything else.

# Auto-commit OFF in test: there's no git repo at /zones inside
