Pre-existing on main, inherited by merging it. `distrust_references` arrived with the RFI anchor work in `93c1ed07`; `RemotePyroWave` did not gain it, and the trait-coverage test beside the impl caught exactly that. The answer is a no-op, for the same reason `invalidate_ref_frames` returns false and `request_keyframe` does nothing: PyroWave is intra-only, so every AU is already a keyframe and there is no RFI anchor trust to withdraw. The in-process encoder reaches the same answer by inheriting the trait default, and that is fine there. It is not fine HERE, which is the point the guard test is making. This type is a proxy: an inherited default means the worker never hears the call, so a method that does something is silently dead on every worker-backed session while the in-process path keeps working. The test therefore requires the method to be WRITTEN, so that "nothing to do" is a visible decision rather than an omission. Written, with the reason. Verified with CI's exact command — `cargo test -p pf-encode --features nvenc,vulkan-encode,pyrowave` — 122 passed, and clippy clean under the same features.
