+Persian diacritization, base tier (run-077): byt5-small seq2seq on
+the 445,869-pair HomoRich-derived corpus (CC0-1.0). IMF v1 fp16.
+
+## Metrics (9,288-row docs split — byte-identical to the rababa-farsi
+reference split; raw char CER, both conventions)
+
+Row-mean CER **0.603%** · corpus-level CER 0.777% · word accuracy
+**82.33%**. The historical 0.52% line is corpus-level under run-001's
+undocumented recipe and does not reproduce (five controlled arms,
+WO47); this is the best verified number.

+## Improvement history (all closed with data)

+epochs (3→6: 0.65→0.60) · backbone (small/base) · optimizer (docs-exact
+5e-4/linear) · metric convention (row-mean vs corpus) · multi-arm
+oracle distillation (run-080/081: arms too correlated, 10.0%
+disagreement — MISS). Remaining untried: corpus rebuild to the raw
+528,837 rows.

+## License

+cardData). Weights and code: BSD-3-Clause.
