Cause (Documented platform behavior): Models download on first use by default; for offline use they must be prefetched and artifacts_path must be a directory containing all required models.

Problem details
- Observed symptom
- Conversion fails at pipeline init when artifacts path is set but is not an existing directory; without it, first use tries to download models from Hugging Face.
- Context
- Product: Docling Component: Pipeline model loading (artifacts_path / DOCLING_ARTIFACTS_PATH) Operation: DocumentConverter(...).convert() with PdfPipelineOptions(artifacts_path=...) or DOCLING_ARTIFACTS_PATH Affected versions: unknown Environment: air-gapped / offline containers Exception: RuntimeError Packages: docling main at pinned SHA Trigger: Pointing artifacts_path/DOCLING_ARTIFACTS_PATH at a missing or wrong path (e.g. not mounted), or deploying offline without prefetching.

solution · Revision 1
Proposed fix: [Docling] offline/air-gapped: "The value of self.artifacts_path=... is not valid. When defined, it must point to a folder containing all models required by the pipeline."
Recommended action: Prefetch with `docling-tools models download` (plus `easyocr --easyocr-lang ...` or download-hf-repo for extra models), ship the folder, and set artifacts_path / --artifacts-path / DOCLING_ARTIFACTS_PATH to it.
Option: Prefetch models and point artifacts_path at them [evidence: official_recommended_action]
Applies when: Offline deployments
Steps:
1. docling-tools models download (on a connected machine)
2. copy ~/.cache/docling/models into the image
3. export DOCLING_ARTIFACTS_PATH=/path/to/models
Expected: Conversion runs without network
Evidence basis (self-declared by the contributing chat client): untested.
