 think all other occurrences end with two underscores, not three.

 Yes, you are right. Indeed, coverity seems to have a revision of the
 codebase with 3 underscores, but that's not the case in master (since
 `48a574604bef`):
 https://github.com/torproject/tor/blob/master/src/lib/math/prob_distr.h#L56

 CID `1444641` was also fixed in #30180 and yet it still appears in the web
 interface.

 Finally, wrt CID `1415723` (mentioned in the comment above), the CID does
 not appear in the web interface anymore (but i did receive it in an email
 on the 30th of April). The assert I was refering to is
 https://github.com/torproject/tor/blob/master/src/feature/client/circpathbias.c#L189

 tl;dr coverity has a dated version of our codebase, and also sends emails
 about fixed issues. Not sure what we could do here, since I dont see a
 button that pulls the latest git rev.
