| ADR-1204 | GPU ADM contrast-masking twins clamp the far edge instead of mirroring it |
| ADR-1205 | The ssimulacra2 FMA unification extends to the scalar fallback and every GPU host copy |
| ADR-1214 | The float-ADM GPU twins ignore adm_csf_scale in Watson mode and share the CPU's option aliases |
| ADR-1219 | The HIP and Metal CAMBI twins use the shared TVI bisection and the CPU's border rules |

| ADR-1472 | The integer ADM weight limits follow from the contrast-masking cube and the largest wavelet coefficient of a scale |
| ADR-1475 | The quantisation step of integer ADM is Netflix's expression again, so vmaf_v0.6.1 returns Netflix master's bits |
| ADR-1489 | The CSF weights of float ADM are Netflix's float arithmetic again, so float_adm differs from Netflix by the division alone |

| ADR-1601 | integer VIF forms the denominator log argument sigma_nsq + sigma1_sq in uint32_t |
| ADR-1679 | The Metal IOSurface import reads NV12 and P010 surfaces itself, and the FFmpeg filter imports whole frames |
