The capability matrix admits #0..99999 on 30i/31i/32i (and anything on Unknown), and
the FOCAS/2 request block has always carried 32-bit arguments, but WireFocasClient cast
every number to short: MACRO:99999 asked the CNC for #-31073 and published that variable
at Good under the authored tag. FocasWireClient's macro/parameter reads, WireMacro.Number
and WireParameter.DataNumber are now int; the request blocks come from MacroRequest /
ParameterRequest builders (byte-identical to the live 31i-B capture for #500).
Same class on PMC: a range whose last byte passes 65535 (Unknown series admits it) is now
refused BadOutOfRange instead of wrapping onto a different 16-bit address.
The wire client is in-process (the other end is the CNC itself), so this is not a
cross-repo contract change. Whether a real 30i honours cnc_rdmacro Arg1 > 32767 is the
hardware userGate.
