docs(AS): AS3 REVIEW-CLOSED (APPROVE, no fix round); R3 legend hedge settled at source

The AS3 dual-lens review verified the armor-level trio, sentinel, legend,
and monster-path exclusion at offset level and disproved the R3
BN-flattening theory structurally (legend sits outside the InqCreature
block, pseudo-C line 189962). The ratings adjudication resolved in the
implementer's favor: the pre-AS3 composer already had retail's per-row
gating and spacer discipline. NITs 11/12 + the AP-110 narrowing ride AS4.
