Description of issue

I'm getting a lot of problems with brew recently where packages fail to download completely and brew seems to have no idea how to handle this. It tries to resume packages with the progress going well beyond the total size, then after this download concludes, it wil try to install, I'm guessing, but then start downloading the same package again. There is no error, it just silently goes into stupid mode where it doesn't acknowledge any problems, seems to try to fix unacknowledged problems, fails to do so, and generally fail loops.

I can't really paste anything all that relevant, but maybe this is a clue:
⠞ Bottle python@3.14 (3.14.2_1) ###### Downloading 10.8MB/ 18.7MB

It says 10.8 out of 18.7 then proceeds to download until it shows something like 23MB / 18.7MB then proceeds to install by....downloading it again:

⠳ Bottle python@3.14 (3.14.2_1) Downloading 9.4MB/-------

9.4MB and counting out of unknown MB.

It's been fail looping for hours.

I'm guessing this is because I'm currently remote and everyone developing for brew has reliable high speed internet and thus never have partial or interrupted downloads.

Update: It appears that when brew resumes a partial download and finishes downloading, it fails to rename the binary to remove the .incomplete suffix.

News to nobody: it downloads 32MB of data every time you run it. Amazing.
