… on draft PRs Bump PRIMUS_TURBO_COMMIT to Primus-Turbo main (0.3.x, validated build) which exposes the mxfp4 gemm_fp4_impl(..., preshuffled=...) fast path, and PRIMUS_TURBO_AITER_COMMIT to AITER v0.1.14.post1. Mirror the turbo commit into benchmark.yaml; the docker build receives both via ci.yaml build-args. Add a draft-skip guard to the expensive jobs (build-docker, run-unittest-torch, run-unittest-jax) so the stacked Flux PRs can sit in Draft without firing the full pipeline; code-lint stays ungated. Add ready_for_review to the pull_request trigger types so flipping a draft to Ready triggers the first run. MEGATRON_PATH export intentionally omitted: the Flux diffusion unit tests run in-process (no megatron-importing subprocess remains after the te_vs_local in-process conversion), and tests/conftest.py auto-adds third_party/Megatron-LM to sys.path when MEGATRON_PATH is unset. CI already checks out submodules: recursive, so megatron imports without any extra env.

Part of an 18-PR series splitting the Flux diffusion-training feature (training Flux, a DiT text-to-image diffusion model, on Primus/Megatron) out of one large branch for reviewability. Targets
feat/flux/data— review after it.What this changes
The offline data-preprocessing layer (auth / download / finalize / validate plus the raw/ingest/encoded pipeline stages), wired into a new
primus dataCLI subcommand.Dependencies
Sequenced after the CI-pins PR (
feat/flux/ci-env); builds onfeat/flux/data(uses its providers and inherits the energon/webdataset deps).Test plan
pytest tests/unit_tests/backends/megatron/diffusion/data/preprocessing tests/unit_tests/cli/test_data_config.py. Validated locally on an AMD GPU container: 63 passed.Files
20 (preprocessing pipelines, data CLI subcommand + tests).
