D2c M4, gate 7 (delete). - int_hyper_synth::decode_conditional, the unchecked conditional decode, is deleted; its callers decode through decode_conditional_checked (the lowering, with its check ranges): the int_hyper_decode_frame example (step 3 of tools/wai_sota_vectors.sh), wai_decode_bench's tiny-vector case, int_payload's JSON-equivalence unit tests, tests/int_hyper_synth.rs, int_kernels_vectors.rs, int_video_keyframe.rs, int_video_sota_keyframe.rs, and byte-exact's neural_keyframe_golden (the trap: it gains the check ranges, outputs equal; gate 2's duplicate test through ops::decode goes). - The pretrained synthesis-only and hyper-decoder-only goldens (tests/int_hyper_synth.rs) are also held through the lowering. - The conditional codec's direct guard (legacy's run_checked) is test-only since gate 6. run_net_checked, check_layer and igdn_check stay: their one production caller left is int_mlicpp (M5); run_net and decode stay for the world renderer (M6), and int_hyper_synth's kernel_equivalence with them, since their conv dispatch is still run_net's. Docs say so. - Doc references (int_video, int_video_golden, two tools) and CHANGELOG. Co-Authored-By: Claude Opus 5.5 <[email protected]>
