requirements.md H1a → [x]: the per-command near-miss matrix (entry words,
missing clauses, committed multi-forms, both modes) plus the gap fixes
(G1 `1:n relationship`, G2 select projection gloss, G3 mode-aware usage
showing all valid forms, G4 `with` CTE template, CROSS JOIN ON teaching
message) close the systematic pass. The advanced-SQL items the survey
flagged (INSERT…SELECT count, RETURNING scope) were verified already
present. One low-priority residual is deferred by decision (submit-time
expression first-set at non-projection positions).
ADR-0042: record the pre-existing `SELECT *` arity caveat (INSERT…SELECT
with a star projection isn't expanded for pre-flight arity; engine
catches it at execution — adjacent to ADR-0019 §OOS-2).
