rajamesandClaude Opus 5.5 32753f5479 feat(v4): the machine has a ROM -- read and run, never written
A read-only range of V4_ROM_WORDS words at V4_ROM_BASE, above RAM
(MACHINE.md 2, DATASHEET-F18.md 5).  Instruction fetch, @p and data fetches
read it; a running programme's store there is an address fault.  Attached by
the owner like every device; a reset detaches it.  The host node's range is
4096 words.  text.c places branches by the whole address space.  The
nucleus image is byte-identical.
