[Proteina-Complexa] `complexa validate target` reports false failures for valid targets

complexa validate target checks DATA_PATH/target_data unconditionally (validate.py:392) and can't resolve target_dict_cfg from the pipeline config, so it reports a failure even for targets that design successfully.

Severity: Medium · Status: open

Steps to reproduce

1. complexa validate target <a shipped target that designs fine>.
2. → validation failure, even though complexa design works on the same target.

Fix

Make the DATA_PATH/target_data check conditional / resolve target_dict_cfg properly. Workaround: use complexa validate design or a smoke design run instead.

Environment

NVIDIA A100 80GB PCIe · driver 565.57.01 · CUDA 12.7 · repo branch dev @ 916eaae · UV runtime.

Start at validate.py:392 and trace how complexa validate target resolves target_dict_cfg from the pipeline config. Reproduce with a shipped target that designs successfully, then verify the DATA_PATH/target_data check is conditional or resolves the configuration correctly and no longer reports a false failure.
