Generated by the /sync-upstream skill in port-only mode. Read-only planning artifact; no code is ported by this PR. Companion to the prior 2026-04-29 quarterly snapshot in docs/upstream-backlog-audit-2026-04-29.md.
Upstream tip: 151a9822 2026-05-02 Merge pull request #1509 from Netflix/feature/routine-test-additions.
Fork tip: e266bf8e 2026-05-02 feat(vulkan): T7-29 part 4 — v2 async pending-fence ring (ADR-0235) (#241).
Range scanned: last 50 upstream commits (49 unique entries).
Method: extracted upstream-master commits with git log upstream/master -50, cross-referenced each upstream short-SHA against SHA mentions in fork commit messages (titles + bodies, all branches). A match marks the upstream commit PORTED on the fork. Unmatched commits are then triaged against the prior quarterly audit and the relevant ADRs to derive PORT / DEFER / SKIP.
These 20 upstream commits are referenced explicitly by short-SHA in fork commit messages, so they have already been picked up via /port-upstream-commit or folded into a larger fork PR.

libvmaf: add support for VMAF_FEATURE_EXTRACTOR_PREV_REF
32b115df
libvmaf: add experimental VMAF_BATCH_THREADING and VMAF_PICTURE_POOL threading modes
small portability fix; partner to the already-ported 32-bit ADM/cpu fallbacks (PR #212). Unblocks fork's i686 cross build (ADR-0151).
49d46e23
libvmaf/predict: port chroma_from_luma correction
numerical-correctness bugfix in the predictor path; touches code the fork still mirrors verbatim. Verify Netflix golden gate after picking.
de538216
feature/integer_vif: port vif_skip_scale0
follow-up bugfix on integer_vif; feeds into the ongoing T-NEW vif-divergence reconciliation. Small, scoped.
4f5e366b
integer_motion: fix dict leak in motion_force_zero case
clear leak fix; no fork divergence in this branch of motion. Trivial port.
9a2ca9b4
Fix enable_tools=false breaking test builds (#1474)
depends on 84614a8b (enable_tools option). If we take that, take this.
7c4beca3
Fix models symbols names when vmaf is compiled as a subproject
improves embeddability — relevant to mcp-server/, FFmpeg patch consumers, and possible meson subproject consumers. Self-contained meson change.
7e16db0a
ssim: add scale parameter to control decimation factor
surface enrichment, additive parameter; the fork has not diverged on ssim.
332dde62
y4m_input: expand to support yuv444p12 / yuv422p12 / yuv420p12
additive y4m support; useful for HDR pipelines. Self-contained reader change.
1b08bb4d
runtime load CUDA driver libraries using nv-codec-headers and support clang compilation
strong-fit improvement for the fork's CUDA backend (clang+CUDA is on the dev matrix). Read carefully against the fork's existing CUDA runtime layer.

python/routine: refactor read_dataset into SubjectiveDatasetReader class
python-harness refactor; fork has its own training/eval harness layered on top (python/vmaf/workspace/). Defer until we re-audit harness divergence.
2f2bb601
python/test: add dataset reading tests for resampling, width/height, workfile_yuv_type
rides on 2e6bbb65. Defer with it.

Merge pull request #1509 from Netflix/feature/routine-test-additions
merge wrapper around the two python/routine commits above. Defer with the parent pair.

libvmaf/feature: update alias map for cambi/speed
partial: cambi half is on fork (PR #160 79288e8d); speed half pends per the prior audit's T-NEW-1. Defer until speed-extractor reconciliation lands.
a44e5e61
libvmaf/feature: port motion updates, bugfix for edge mirroring
fork has consciously diverged on motion per Research-0024 + ADR-0145. The bugfix sub-piece may still be relevant; defer to the next motion-divergence re-audit, do not mass-port.
dae6c1a0
libvmaf/feature: add motion_v2
new metric variant; pairs with the motion-divergence story (ADR-0145). Defer until we decide whether to absorb motion_v2 or keep the fork's bespoke variant.
CI-config delta; fork manages its own CI matrix per ADR-0151.
f6d6dde1
gh: add 32-bit cross build to CI
same as above — fork has its own i686 build-only row (PR #87).

build(deps): bump actions/upload-artifact 5→7
dependabot is enabled on the fork; bumps land independently.

dependabot-on-fork (same reasoning).

Bump actions/setup-python 5→6

feature/adm: temporarily disable adm_decouple_s123 x86 simd
upstream temporary regression mitigation; fork's SIMD path has progressed past this state — the underlying defect either does not reproduce on fork or has already been addressed by later fork SIMD work. Re-confirm before any future port.
6375a4be
tools/cli_parse: add --aom_ctc v7.0
fork has diverged on CLI semantics (full-precision --precision, etc.); CTC presets are tracked separately in the CLI roadmap.
b044ae39
tools/cli_parse: add CHECKED_REPLACE
upstream-internal CLI helper macro; fork's cli_parse has its own structure. Re-port only if/when CTC-preset work is taken on.
850b9a67
tools/cli_parse: use CHECKED_APPEND
same group as above.
45e2bd52
libvmaf: make vmaf_register_metadata_handler private
API-narrowing change. The fork still exposes the symbol (and FFmpeg's vf_libvmaf patch consumes the public surface). Skipping preserves ABI stability per ADR-0186 (FFmpeg-patch invariant).
84614a8b
Add enable_tools option (#1460)
meson-options surface change — would require an ADR on fork; fork already has its own meson option topology. Skip unless an explicit need arises.
44a92543
Additional AVX optimizations with build and vmaf accuracy fixes (#1452)
fork has independently diverged on AVX paths (see Research-0024 and the multiple ADR-0142/0143/0144 family entries). Re-porting risks reintroducing rounding deltas that the fork's golden gate already locked down.
f5f36644
core/meson: build libsvm as separate static lib
fork's meson layout has fork-specific library partitioning; would require an ADR. Skip pending a meson re-architecture review.
