Review noted the "never throws" claim was overstated: the exact-case Optional lookups still surface a NonUniqueResultException on two byte-identical same-case rows. That is a true data anomaly out of #731's scope (ambiguous = case-insensitive) and resolves to the opaque INTERNAL_ERROR, never a wrong row. Record that boundary at both resolution points and in ADR-032 so the gap is not silently assumed covered. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
