Surfaces from a Devil's-Advocate audit of the DSL → SQL teaching echo (ADR-0038) after Phases 1-3 landed: three doc-drift bugs introduced by the earlier handoff-47 / ADR-promotion commits — requirements.md M4 and both ADR-0038 README index entry + Status block still said "Phase 2 / Phase 3 remain," but `275c726` and `e6ad1ae` shipped them. Updated to reflect actual state: Buckets A + B complete plus the category-3 prose; only the §4 styled-runs polish remains. ADR-0037's README entry also touched to note all four shipping commits of its consumer. Plus a missing test slice the DA flagged: explicit no-echo coverage for the Bucket C cases that flow through command_to_sql's catch-all (show table, explain, replay, every Command::App variant). The contract — ADR-0030 §10 / ADR-0038 §7 Bucket C — forbids echoes for these; a future renderer arm added at the wrong place could silently leak one. The new bucket_c_no_echo_commands_all_return_none pins that. Tests: 2015 passed / 0 failed / 1 ignored (pre-existing); clippy clean. Nothing to escalate.
