Why this is a false positive

The work in progress is debugging a video codec implementation — tracing frame corruption through the bitstream parser and entropy-decoding stage of a standard compressed video format. This is ordinary multimedia software development, with no security-offensive component: the goal is to correctly reconstruct frames from a malformed or partially-decoded stream, not to exploit, evade, or attack any system. The cybersecurity classifier appears to have keyed on low-level terms common to both codec internals and security tooling (bitstream parsing, corruption, malformed input), producing a false positive on legitimate, in-scope engineering.
