D-1 word addressing; D-2 F18 circular stacks (10/9 deep), hidden, so
DEPTH/PICK/ROLL/.S/SP@/SP! are retired everywhere and the DSP register is
dropped; D-3 plain F18 +* (UM* flagged for revision); D-5 host width
matches the host CPU; D-7 moot; D-8 signed Q48.16; D-4 and D-6 deferred
to the hosted-mesh step. Adds a note that every CAP definition must be
re-checked against the 10/9 stack depths.

JUSTIFICATION.md records why v4 exists and the reasoning behind each
major design decision. DECOMPOSITION.md assigns every v3 C primitive a
fate on the 32-instruction F18-derived core.
