	// HeaderTestEppEndPointSelectionKey is the request header used in tests to control
	// Endpoint Picker (EPP) behavior deterministically.
	//
	// The header value is a comma-separated list of endpoint identifiers. Each entry
	// may be in one of the following formats:
	//
	//   - "IP"          — selects all pods whose IP address matches the given value.
	//   - "IP:port"     — selects only pods whose IP and port both match exactly.
	//                     Ports correspond to data-parallel ranks or specific targetPorts.
	//
	// IPv6 addresses are supported, with or without brackets (e.g. "fd00::1" or "[fd00::1]:3002").
	// The returned order matches the order of endpoints specified in the header, and duplicates
	// are ignored.
	//
	// Examples:
	//   "test-epp-endpoint-selection": "10.0.0.7,10.0.0.8:3002"
	//   "test-epp-endpoint-selection": "[fd00::1]:3000,fd00::2"
	HeaderTestEppEndPointSelectionKey = "test-epp-endpoint-selection"
