Amendment 2 records the §10.6 fixup-pass mechanism choice. §10.6 prescribes "rewriting the highlight class" on projection-list idents at end-of-walk; the actual implementation uses a different mechanism that achieves the identical user-visible behavior: 1. 2d's two-pass schema-existence diagnostic collects every FROM binding from the matched path first, then resolves projection idents against the complete scope. The post-walk re-resolve §10.6 calls for, just embedded in the diagnostic emitter. 2. input_render.rs's diagnostic-overlay path colors each diagnostic span Error/Warning, achieving the visual change §10.6 describes without needing a new HighlightClass variant. The completion-mid-typing piece is improved by the §10.5 look-ahead probe (sub-phase 2e earlier). Four new regression tests in `projection_before_from_tests` pin the behavior so a future refactor can't silently regress it: correct ident resolves silently, unknown ident flags via diagnostic on its span, multi-projection only flags unknowns, projection-without-FROM is silent. ADR index entry updated to reference Amendment 2. Test totals: 1424 → 1428 passing (+4). Clippy clean.
