Close the three remaining ADR-0042 triage gaps, each test-first, and lock the advanced-mode near-miss matrix. G2 — bare `select` dumped the 14-item expression first-set. Collapse it to "a projection: `*`, a column, or an expression" in the error message only (parser::format_walker_error), detected by the joint `distinct`+`all` quantifier signature unique to a projection start. Render-only: completion/hints still expand the full set (typing-surface matrix unchanged). G3 — the usage block was mode-blind: advanced `create table` showed the DSL `create table … with pk …` template. usage_key(s)_for_input gain mode-aware `_in_mode` variants selecting candidates by CommandCategory; render_usage_block and the typing-time ambient usage thread the submission mode. Advanced `create` now shows both SQL forms. A fallback covers shared SQL nodes (insert/update/delete) that declare no usage_ids of their own — without it they regressed to the available-commands fallback (caught by the new advanced matrix). G4 — `with` borrowed `select`'s usage template; give it its own parse.usage.with CTE template. Tests: new near_miss_matrix_advanced_mode (12 SQL-surface cases incl. the available-commands regression guard) + per-gap tests; removed the temporary baseline_dump. Full suite green (lib 1578 / it 386 / typing_surface_matrix 192); clippy clean.
