If an audit discovered that the CA misissued AND discovered that fact,
then the audit would fail. It might be possible to claim that the
misissuance was never discovered though.
The proposed text helps, but does not completely resolve this issue.

Within one week of discovery, the CA must issue the report. A CA might
not have discovered the issue before, but once made aware of it, they
have one week to go public. If discovered by CT (aka the public), the
public would know if the CA complies, and if discovered by the auditor,
the auditor would know if the CA complies.
