ADR-0020/0021 specified a chumsky-based H1a; ADR-0024 replaced chumsky with the scannerless walker, leaving both obsolete. Mark them superseded (kept as institutional memory) and add ADR-0042, which restates H1a against the architecture as built. ADR-0042 records that H1a is substantially shipped already — per-command usage block, available-commands fallback, source-derived ident slot labels, curated parse.custom.* near-miss messages, and schema-aware [ERR] diagnostics — and defines the remaining work: a verified per-command near-miss matrix (the definition of done), friendlier literal expectation labels that add role context while keeping the exact literal visible, and advanced-mode SQL parse parity (RETURNING scope, CROSS JOIN ON, INSERT…SELECT count), kept distinct from ADR-0019 §OOS-2 engine-error sanitisation. - docs/adr/0020,0021: superseded notes + README entries - docs/adr/0042: new ADR - docs/adr/README.md: index upkeep (ADR-0000 rule)
