Summary

  • New O_EVAL_JSONL epilogue mode for train_oracle_student_hf.py: when set, the post-training epilogue evaluates greedy CER on a {src, tgt} jsonl (up to 1200 rows) and returns before the Arabic-specific SadeedDiac/WikiNews surfaces
  • Needed for non-Arabic oracle runs (run-088 Urdu): the Arabic eval mounts do not exist there and the epilogue previously crashed after checkpoints

Test plan

  • python -m ast parse check
  • In use by the run-088 stage-2 launch (val split eval)

When O_EVAL_JSONL points at a {src, tgt} jsonl, the epilogue evaluates
greedy CER on it (up to 1200 rows) and returns before the
Arabic-specific SadeedDiac/WikiNews surfaces — for non-Arabic oracle
runs (run-088 Urdu), whose val splits live in the corpus bucket rather
than the Arabic eval mounts.
