Prerelease: no

Release notes:

Breaking Changes

• Remove legacy AV pipeline and PostgreSQL helper modules; see Removed for affected paths.
• Remove the unified Pixi environment; use default for stages and commands that previously

selected unified.

Added

• Add cosmos-curator pipeline config tooling for Ray Data pipeline configs:
• template prints editable config templates.
• validate checks resolved JSON/YAML configs.
• render emits the canonical resolved config used for execution.
• schema prints the supported config JSON Schema.
• presets list and presets show inspect packaged presets.
• Add schema-validated Ray Data video_split configs with defaults, packaged presets, template

profiles, strict field validation, and --set dotted-path overrides.

• Add split-comparison measurement schema and field-spec catalog for typed measure/evaluate flows.
• Add caption quality statistics to split benchmark summary metrics.
• Add shared caption embedding helpers for split-comparison measurement code.

Fixed

• Reject invalid curator-side uint8 video preprocessing configurations before execution.
• Force model-side preprocessing for Nemotron in the split pipeline.
• Centralize vLLM preprocess-mode handling across supported vLLM model wrappers.
• Return NVCF API response status codes when surfacing API errors.
• Improve image-build CI behavior and allow pre-commit setup to run on macOS.

Changed

• Split Pixi tooling into narrower developer, tooling, cluster, runtime, and model-specific

environments to reduce development-environment weight.

• Keep the Pixi developer environment slimmer by moving runtime-heavy dependencies out of the

general dev feature.

• Reduce Slurm end-to-end CI inode usage.
• Update Ray Data split pipeline internals to execute through resolved config objects.

Removed

• Remove the legacy AV pipeline package:
• cosmos_curator.pipelines.av is no longer included.
• The old AV pipeline reference documentation is removed.
• Remove PostgreSQL helper modules that supported the legacy AV pipeline:
• cosmos_curator.core.managers.postgres_cli is no longer included.
• cosmos_curator.core.utils.db is no longer included.
• Remove the unified Pixi environment after folding its common GPU-capable runtime dependencies

into default.

Documentation

• Add pipeline-config design documentation for schema-versioned config files and config tooling.
• Add Pixi environment design documentation for the split developer/runtime environment layout.
• Refresh deprecation and split-comparison design notes for the new config-driven and measurement

workflows.
