The cek_run import handling (resume after hook loads library) caused
cek_step_loop to infinite-loop during aser page rendering. Root cause
not yet identified — the resumed CEK state never reaches terminal.
Reverted to original cek_run that throws "IO suspension in non-IO
context". The 4 server startup errors are harmless (files load
partially, all needed symbols available via other paths).
Import hook re-entry guard and debug logging retained for future work.
