The check reads the rows + above the choices (the choices only echo the command), and a blank row ends + a paragraph. + - **Wraps:** a row boundary may fall between words or inside one, and the + grid cannot tell which. The words on both sides are kept as separate words + and are also offered glued together. The check stays linear in the length + of the paragraph, however its wraps mix. + - **Quoting:** words are split twice, once shell-quoted and once plainly. A + quoted path such as `"/tmp/my project"` stays one argument, and a quoted + program (`| 'bash'`, `sh -c '…'`) is still seen. + - **Position:** rules ask what appears after what, never where. A flag can + appear anywhere in the command (`git clean target -f`). A git subcommand is + found by name, so global options such as `-C ` need no parsing. + Programs are matched by basename (`/bin/rm`). + - **Rules:** `rm -r`/`--recursive`, `sudo`/`doas`, forced `git push`, + `git reset --hard`, `git clean -f`/`--force`, `--no-verify`, a pipe into a + shell (`sh`, `bash`, `zsh`, `dash`, `ksh`, `fish`) or `sudo`, recursive + `chmod`/`chown`, `dd of=`, `mkfs*`, `diskutil erase*`, + `shutdown`/`reboot`/`halt`, and `DROP TABLE`/`DROP DATABASE`/`TRUNCATE + TABLE`. + - **Ambiguity resolves toward denying.** A false hit costs only a manual + approval. For example, `| grep sh` is denied, as is a destructive command + named only inside a commit message. +- A hit withholds the automatic answer, and the dialog waits for the user as + it would with the mode off. `NOA_AUTO_APPROVE_TRACE=1` logs the rule that + matched. The check is best-effort: it sees only what the dialog paints, so a + command an agent elides (agy's `⋯ (n lines hidden)`) or wraps in a script can + still pass. + +## 2026-10-01 revision — breaker re-enable + +The runaway breaker no longer keeps a latch in the io thread.
