also 0 violations. The NotAttempted decline is COMMON on the default path
(~41/130 fixtures), so its diagnostic eprintln is gated behind
`SYNTH_RA003_VERBOSE` (a production compile stays quiet; the verdict is
observable on demand). Extending invariant 4 to the numeric-branch
optimized path (a resolved-offset CFG builder, the #606 geometry) is a
NAMED follow-up. CI-gated: the third `vcr-ra-003-alloc-validator-gate`
observable on demand). v0.50: invariant 4 now ALSO runs on the
numeric-branch OPTIMIZED path — a resolved-offset join-CFG builder decodes
BOffset/BCondOffset targets to predecessor indices so the MUST-availability
fixpoint runs there too (6 new `ra003_numeric_*` tests: red across-join
clobber CAUGHT, green both-paths/dominator/loop-back-edge Consistent,
off-boundary + mixed-stream still decline). NotAttempted stays only for
genuinely-unresolvable offsets (decline>guess). CI-gated: the third
`vcr-ra-003-alloc-validator-gate`
step runs `scripts/repro/vcr_ra_003_phase2_join_call.py` over
branchy/mem/call fixtures on BOTH paths (silent-on-real-branchy-codegen).
