rajamesandClaude Opus 5.5 11b5d402b1 feat(v4): the shared math in both ROMs, and a mesh node's ROM 
MACHINE.md 2.2.  UM*, UM/MOD, D+, DNEGATE, Q.* and Q./ are entries 0-5
of the host ROM and of a mesh node's ROM, from one source (rom/math.f18)
and one entry list (v4/rom_entries.h).  The host ROM starts at entry 18.
The mesh ROM is 277 words; the host ROM 2372.
