Trace review showed the split rule firing on commands with no execution at all: curl downloading a `.js` asset (`curl …/app.js > app.js`), glob and grep patterns containing a script suffix, and running an inspectable workspace script with an output redirect (`python3 probe.py > out.jsonl`). It blocked on any interpreter segment or any token ending in a script suffix. Block only the shapes whose executed code no artifact can describe: an interpreter that reads from a pipe, stdin, or heredoc, and create-then-run where a script-suffixed file is written (`> x.py`, `-o x.py`) and executed in the same expression. Running an inspectable script with its output redirected or piped, and downloading a script-named asset, now go to review — the script itself is still read into the packet. Destructive-in-a-chain detection is unchanged. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
