17 of 23 words fully modelled (Q.+/-/*//, Q.ABS/NEG, Q.FROM-INT/TO-INT, Q.1/0/SCALE, Q.=/</>/0=, Q.MAX/MIN), reusing q48_add/q48_mul/q48_div/ q48_from_u64/q48_to_u64 already in StarForth_Q48_16.thy and cell_abs (Q.ABS's raw sign-bit test is bit-for-bit cell_abs's `n <s 0`). Added q48_sub there alongside, the one missing arithmetic primitive. Q.LOG/EXP/SQRT/SIN/COS deferred (same transcendental-approximation class already excluded from the sweep at q48_16_words.c). Q.PRINT deferred (stdout only). Finding: every word in this file pops/pushes via the VM_POP/VM_PUSH macros, which resolve to completely unchecked vm_pop_fast/vm_push_fast when STARFORTH_PERFORMANCE is defined -- a build-flag-gated stack-safety hazard distinct from (and broader than) the individual missing-guard instances found elsewhere in the sweep, since it silently disables every guard in the entire file at once. Modelled assuming the safe path. Suite now 52 theories, green.
