package relay_test

// This file, alone in the package, is relay_test (an EXTERNAL test
// package) rather than relay: it asserts that BuildConfig's value is safe
// to materialize into an EnvironmentFile, which means importing
// internal/appconfig for ValidVarValue — and internal/appconfig imports
// internal/relay for real since Task 12 (configack.go, relaySuffixesFromRelayVar).
// An INTERNAL relay test importing appconfig would close relay ->
// appconfig -> relay, which go vet refuses; this package, built separately
// from both, does not.
