the cheat measurement, silently, because the repair leaves no failing test behind.

"""The command classifier.
Sandbox exec events record the command as one string, and the stock tools reach
the filesystem through verbs nobody would guess from the tool name: `read_file()`
runs `awk`, `list_files()` runs `find --`, `grep()` runs `grep -rn`. Rungs 1, 3
and 6 are decided on what these commands did, so a misclassification here is a
wrong number in the paper rather than a crash.
