nx_conductor_live_wms_gate.nx

nx_conductor_live_wms_gate.nx -- the REFEREE for WMS LIVE-1 + LIVE-3 (conductor adoption). LIVE-1 (conductor heartbeat): the live conductor now beats "HBX ws=1 ... END" each loop iteration via a single locked fa_appendz (cl_hb_beat). This lane proves that heartbeat is M1-detectable: a freshly-beaten conductor ws reads HB_ALIVE, and a conductor that stopped beating (aged beat) reads HB_STALLED -- so a REAL crash surfaces, not just a test channel. (NEG side: STALLED proves the detector isn't a constant-ALIVE.) LIVE-3 (event-log torn-write kill): cl_event was 8 sequential sys_write calls to one O_APPEND fd; it is now ONE assembled locked fa_appendz. GOOD lane = 16 workers emit the migrated cl_event shape concurrently -> ZERO torn lines, all present. BAD lane (mandatory NEG-CONTROL) = the SAME records emitted the OLD multi-write way -> concurrent interleave -> torn lines MUST appear. TAMPER: an oversized record is REJECTED (-2). A cl_event line is WELL-FORMED iff it starts "beat=" AND contains exactly one "beat=" head AND exactly one " ms=" field token -- any interleaving duplicates/breaks those. GREEN(0) iff: good_torn==0 AND good_lines==N*NRECS AND bad_torn>0 AND tamper==-2 AND conductor ALIVE AND crashed STALLED.
