A case of a cyclist who tested too high for salbutamol and subsequently got cleared would never be know about publicly (if there are no leaks). There may be many, there may be none.
It seems that after the point at which UCI offered a cyclist "Acceptance of Responsibility" but the cyclist rejected it, then there will be a record of the fact the case was referred to Anti-Doping Tribunal
Article 7 Confidentiality

be used only in connection with the disciplinary proceedings at hand.
2. Likewise, all Parties as well as the Secretariat, witnesses, experts, interpreters or any
other individual involved in proceedings shall keep confidential any information
disclosed in connection with the proceedings.
3. Para. 2 above does not restrict UCI’s right to make
public announcements regarding
the existence and status of any pending matter.

So it seems there aren't secret Anti-Doping Tribunal cases, the UCI definitely doesn't have to conceal any case at that point. And I don't see what their motive would be in: both sending the case to Anti-Doping Tribunal, and at the same time, pretending the case no longer exists
If the cyclist is acquitted, then what the case was about, and why they got off, can remain secret at the request of the athlete... but there is still a record that there was a referral to Anti-Doping Tribunal. That's my impression based on the documents
