## Message

```
ep: Add LCS-based recall (#53509)

This PR adds the `correctly_deleted_chars` field and updates `kept_rate`
to account for it, not just inserted chars.

It also adds `recall_rate` to measure coverage of reference
insertions/deletions.

Finally, it renames "final" to "reference" and "prediction" to
"candidate".
