The ~820-line tail of free builders — make_frame/make_frame_csc/ make_frame_common, make_video_image, probe_rgb_direct, the H.265/AV1 parameter-set writers and the AV1 bit-writer — moves to a #[path] child module, the amf_sys.rs shape: the child sees the parent's private items (Frame and friends), so the split costs zero visibility churn. Six parent-called items went pub(super); five stay child-private (dead_code is per-item and each is used within the child). vulkan_video.rs drops 5,292 → 4,489 lines and the construction unsafe gets its own review surface; steady-state encode logic stays in the parent. ⚠ Trap recorded for future child-module splits: inline `use super::X` statements INSIDE moved fn bodies silently change meaning (super shifts one level) — vk_av1_encode/vk_valve_rgb imports needed crate:: paths. Proven on-glass, not just compiled: all 8 vulkan GPU smokes green under the validation layers on the 780M post-split (H.265 + AV1, RGB-direct, CSC, CPU paths — every moved constructor exercised). nvenc_cuda.rs and qsv.rs are DECLINED the same treatment, with evidence in the handoff doc: no equivalent self-contained seam — their candidate regions are ~150-line loader/accessor clusters interleaved with the encoders' own state types, and a thin-forwarder impl split is exactly the churn a no-defect phase penalizes.
