nx_vcodec_inter_vm_gate.nx

nx_vcodec_inter_vm_gate.nx -- SOVEREIGN VM verification of the INTER-FRAME (P-frame) path of the shipped nx_vcodec.wasm. The existing nx_wasm_vm_exec_gate proves the KEYFRAME path byte-exact; this proves the TEMPORAL-COMPRESSION path (keyframe=0, coded against O_PREV) -- the actual 9->30fps lever the H9 live-wiring depends on. Flow (mirrors the browser's real inter loop): encode frame A as a KEYFRAME, decode it, copy the decoded recon -> O_PREV (what the browser does between frames), then encode a near-static frame B as an INTER frame (keyframe=0) against that PREV, decode it. Prove, via the ecosystem's OWN wasm VM vs the native codec authority: - keyframe recon VM == native (byte-exact) - inter-frame recon VM == native (byte-exact) <- the new coverage - inter frame costs FAR fewer bits than the keyframe (temporal compression is real) No deploy, no live-client touch -- pure headless de-risk. expect_exit: 0 license_tier: ORIGINAL
