Warning: This filters only a temporary vector whose sole consumer already checks any(|port| *port > 0). Consequently, [0] was already rejected, while [0, 443] still passes and the zero remains in the JSON supplied to OPA. Please either reject any zero-valued ports member or remove zeros during endpoint normalization/proto serialization, then cover all-zero and mixed arrays with regression tests.

I will get to these later today thanks for raising this issue.

Warning (CWE-20): This changes the untrusted agent-proposal parser without testing that path. Please add proposal_chunks_from_body cases for mixed [0, 443], zero-only [0] rejection, and [0] with positive scalar fallback, asserting the resulting proto port and ports. The new OPA helper tests cannot protect this separate parser.

if ports.is_empty() && endpoint.port > 0 {
ports.push(endpoint.port);
