Phase 4 of the ADR-0030 roadmap; clarifies §4. Advanced-mode CREATE/DROP/ALTER TABLE + CREATE/DROP INDEX get their own per-statement Sql* commands, executed structurally (not verbatim) so the playground's types, named relationships, and STRICT stay intact. Full surface (no pre-emptive cuts): constraints, compound PK, FK -> named relationships (one statement = one undo step), ALTER incl. advanced-only table rename (C1), [UNIQUE] indexes. Unified column-type-conversion: lossy refuses in simple mode but proceeds-with-a-note in advanced, with undo as the safety net. Integration (parser/hint/completion/diagnostics/history/replay/undo) is structural via the unified grammar; replay treats DDL as a write. Nine sub-phases (4a-4i). Updates the ADR README index. Status: Proposed (design agreed; implementation pending).
