# ============================================
# Armature Core - Traefik Retry Middleware
# ============================================
# Retries failed requests (502, connection reset) once before giving up.
# Applies to API + WebSocket paths via the Ingress annotation.
#
# Why: After a heavy provider model sync (100+ DB upserts), the Go
# process may briefly delay responses. Traefik sees a stale keepalive
# connection or a slow initial byte and returns 502. A single retry
# on a fresh connection resolves it transparently.
#
# This is applied per-environment (${DEPLOY_SUFFIX} ensures isolation).
