Redaction matched backend addresses exactly, so DNS case variation let an address reach the client.

  • Fold ASCII case when replacing a backend URL, host and hostname
  • Cover the redaction vectors, the same-status agreement rule and the bare-GET premise behind replaying 406/415

Follow-up to #23, merged while this was in review.

DNS names are case-insensitive, so a backend named back in a different
case escaped redaction and reached the client.

- Fold ASCII case when replacing a backend's URL, host and hostname
- Pin the redaction vectors, the same-status rule and the bare-GET
  premise behind treating 406 and 415 as replayable
