Review Comment:
   ⚠️ `initializeService()` explicitly rethrows `Error` after cleanup (lines 
602-608), but this master thread only catches `Exception`. An `Error` from 
`initMaster()`, `execute()`, or `closeMaster()` therefore terminates the daemon 
thread without completing `masterFuture`; `waitForServices()` reports only a 
generic timeout after 310 seconds. Please catch `Throwable` here, as the other 
service threads do, complete `masterFuture` exceptionally with the original 
cause, and add a focused regression where the master task throws an `Error` and 
fails immediately.
