32 consecutive `\xNN` escapes (entropy 5.0 bits/byte) (raw pass, confidence 0.80)

```
likely benign LLM, confidence 0.95 A Rust unit test passing a sequential byte-array literal (0x00-0x1F) to a checksum function and asserting its expected output.
Reasoning
The raw pass flagged a run of 32 hex escapes, but the snippet is a unit test feeding bytes 0x00 through 0x1F into a checksum function and asserting an expected value. The sequence is sequential and predictable, which is typical of test vectors. It is in a test assertion, not executed payload, and there is no decoding or dropper behavior.
