| # urd-g2p-base-1.0 | |
| Urdu grapheme-to-phoneme, base tier (run-059): byt5-base seq2seq on | |
| the full 610K-pair humair025 corpus. IMF v1 fp32 (2.16 GB). | |
| ## Metrics (full 12,699-row test split, raw char CER, row-mean) | |
| CER **15.65** (urd-g2p-1.0 small tier: 15.78 baseline) — gate PASSED. | |
| Normalized CER 10.75. | |
| ## Artifact parity (WO51 contract) | |
| Single-row greedy decode, the runtime's actual decode mode: 500-row | |
| probe recorded in the artifact metadata (the pre-WO51 batched | |
| harness numbers were invalid — batched decode without an attention | |
| mask measures nothing). | |
