An audit of the command surface found the `[ok] <verb> <subject>` summary line duplicated the echo line above it everywhere; its only unique signal was success-vs-error. Retire it: a command's echo line now resolves from `running: <input>` to `<input> ✓` / `<input> ✗` on completion, and the symmetric `"<verb> <subject>" failed:` prefix is dropped (only the reason remains). Content lines (row counts, structure, plan tree, teaching echo) are unchanged. Echo lines carry an EchoStatus; executed commands push Pending and resolve the oldest-pending echo on their result event (FIFO worker — correct under interleaving). Parse-time and pre-flight rejections are not executed and keep their running: + caret rendering. App-command [ok] lines (rebuild/export/replay) are payload-bearing and untouched. ADR-0040.
