// #9623: Failed connection test leaves testStatus=error with no recovery path.
// Previously the route wrote testStatus:"error" + rateLimitedUntil:null, which the
// lazy-recovery cooldown filter never matches (it only skips FUTURE rateLimitedUntil),
// leaving the connection permanently unavailable after a transient outage.
// Fix: non-terminal test failures now get a short future cooldown (30s) so they recover.
