# bug-1542: health_rejoin_test.go referenced C.E_XCE_NOT_READY directly (via -int(C.E_XCE_NOT_READY)), which…

## Description
health_rejoin_test.go referenced C.E_XCE_NOT_READY directly (via -int(C.E_XCE_NOT_READY)), which requires import "C" in a _test.go file -- illegal per golang/go#13938, would have failed to compile

## Environment
_Not recorded (migrated from buglog.json)._

## Reproduction
_Not recorded (migrated from buglog.json)._

## Root cause
Wrote a test helper that needed the -E_XCE_NOT_READY errno value, and reached for C.E_XCE_NOT_READY directly without recalling that _test.go files can never import "C" themselves (established project constraint, see clib_test.go/reconnect_test.go doc comments) -- caught before ever running go test, by re-reading the file before the first test run.

## Fix
Exposed -E_XCE_NOT_READY as a plain Go int via a new package-level var in clib.go (a cgo file): notReadyRC = -int(C.E_XCE_NOT_READY). health_rejoin_test.go references notReadyRC instead of C.E_XCE_NOT_READY -- same plain-Go-signature test-seam pattern as performRejoinFn (reconnect.go, task 4.3).
