1. info warn → info by review encoding-escape-soup src/baseline.rs:76:44

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

           assert_eq!(super::update_slow(0, b"\x00\x01\x02\x03\x04\x05\x06\x07\x08\x09\x0A\x0B\x0C\x0D\x0E\x0F\x10\x11\x12\x13\x14\x15\x16\x17\x18\x19\x1A\x1B\x1C\x1D\x1E\x1F"), 0x91267E8A);
       }

   dismissed LLM, confidence 0.97 A Rust unit test feeding the sequential bytes 0x00-0x1F into a checksum function and comparing against an expected value.

   Reasoning

   The snippet is a unit test asserting a CRC/checksum function against a byte string containing the sequential bytes 0x00 through 0x1F. The escape run is a deterministic test vector, not an encoded payload; the file is a Rust test module (assert_eq! with super::update_slow). The raw-pass encoding heuristic fires on the escape density alone, which is a known false-positive pattern.

Reproduce This Scan

Run disclude locally to verify. These commands scan the published file; the "new in this release" marks come from comparing it with the previous release's file, which they don't repeat. Add --format sarif for SARIF output. Add --llm (with an API key in the environment) to include the LLM review.
