Narrow ADR-0036 from "bind literals via the DSL path" to "validate literal
values (shared validators) + retain them; execute verbatim, keep auto-fill
and command identity mode-specific" — after a concrete auto-fill difference
(non-PK serial) confirmed the modes aren't identical even for single-row
literals. Augments (no longer supersedes) ADR-0030 §4 / ADR-0033 §10;
Amendment 3 stands. README + forward-notes on 0030/0033 updated. Records
requirements.md X4 (serial auto-fill — possible bug) and X5 (framework
cohesion / share-mechanics-not-commands).
