Converts the local CADFS FeatureScript RP corpus to self-contained CDSL 1.1, rebuilds runtime-eligible documents with the current CDSL engine, and compares the rebuilt B-rep with the source STEP.

PYTHONPATH=backend:. python -m cadfs_to_cdsl scan
PYTHONPATH=backend:. python -m cadfs_to_cdsl pipeline --sample-id 00000173
PYTHONPATH=backend:. python -m cadfs_to_cdsl pipeline --limit 100 --seed 0
PYTHONPATH=backend:. python -m cadfs_to_cdsl pipeline

All stages are resumable. Use --force after changing converter behavior. The original CADFS directory is read-only; generated evidence is written under cadfs_to_cdsl/output/samples/<sample_id>/.

Full corpus one-command runner

Run the full conversion, rebuild, comparison, and Markdown report with:

./cadfs_to_cdsl/run_full_rebuild.sh

The default is a forced fresh pass. Before it begins, the previous cadfs_to_cdsl/output directory is moved to cadfs_to_cdsl/output-history/<timestamp>/; it is never deleted or mixed with the new result. Use --resume to reuse the existing output without archiving it, or --compare-mode strict for strict acceptance. See ./cadfs_to_cdsl/run_full_rebuild.sh --help for worker and timeout options.

Representative regression pool

Generate the checked-in representative manifest after a full corpus conversion:

PYTHONPATH=backend:. python -m cadfs_to_cdsl regression-select

The selector deterministically covers every observed FeatureScript modeling operation, sketch entity type, lowered CDSL atomic operation, unsupported operation, and unsupported engine-capability variant. It records which atomic operations have a successful engine baseline and which are diagnostic-only; the latter are never reported as passing builds. A normal engine change has a small, executable STEP regression command:

PYTHONPATH=backend:. python -m cadfs_to_cdsl regression --tier engine --stage rebuild

The command reruns by default; use --resume only to inspect cached results. Use --tier conversion --stage convert to verify feature lowering and diagnostics, or --tier all --stage pipeline for the complete representative conversion/rebuild/compare pass. Unsupported CADFS features remain diagnostic coverage, not expected successful engine builds.
