about

nx_pub_resilient_gate.nx -- proves pub_run_resilient is UN-STUCKABLE (operator: "the publisher cant get stuck again as a whole even if somethings get stuck"). The queue is [good1, CRASHER, good2]; the CRASHER has a 16 KB dest field that overflows the child's fixed buffer and SIGSEGVs the child. Liar-killed proof: good2 -- the item AFTER the crasher -- STILL lands live (head-of-line blocking eliminated), the crasher is QUARANTINED to the dead-letter (reason=CRASH), and the drain reports published=2 crashed=1. In the old in-process pub_run_governed this same queue would kill the whole process at the crasher and good2 would never publish. license_tier: ORIGINAL expect_exit: 0
