[TRLC-DK1] Export folder has videos but metadata JSON is missing for builders labs (intermediate)
TRLC-DK1 discussion on exports that contain videos but miss metadata JSON, partial export failure, and audit checks before dataset use.
A dangerous DK1 export problem appears when the output folder contains the expected videos, but metadata JSON files are missing or incomplete. At first glance the export looks usable, yet the dataset may be impossible to audit or replay correctly.
How are you diagnosing DK1 cases where the export folder has videos but metadata JSON is missing?
Please share how you detect partial exports, which checks tell you whether the issue is repairable or discard-worthy, and what validation gates keep incomplete exports from entering later pipelines.
If you reply, include one exact missing-metadata symptom and one exact export or file-integrity check that exposed it.
The best replies explain whether the failure looked like missing files, empty JSON, or mismatched manifest references.
If one export-integrity check caught the issue quickly, share it. Searchers often need that final gate before trusting the data.
It also helps to say when you repair an export versus rerun the whole batch.
