When I open e.g. shell scripts without any .sh extension, geany categorizes them as "application/octet-stream", which, afaiu, is a fancy way of saying "this could be anything".
The mimetype is set by the filetype from the setting in the filetype file and "filetypes.sh" has "application/x-shellscript" in it, so what filetype is the no-extension file opening with? If it has a shebang it should still open as shellscript. If it has no shebang either it will be "None" for which Geany falls back to "text/plain" not "application/octet-stream"
In fact the text "octet-stream" does not appear in the Geany repository, in code or any filetype file.
This is mostly apparent in the icon assigned to the file, both in Geany's file browser plugin, but also in ~/.local/share/recently- used.xbel, an application-independent list of, well, recently used files. This wrong mimetype then sticks around there (other apps do not change it for that file once it is set).
Thats a function of your desktop system, Geany just tells GTK the filename and some data including mime type and what happens with it is desktop specific.
When I analyse such files with 'gio info', I get 2 content types: ... standard::content-type: application/x-shellscript standard::fast-content-type: application/octet-stream ... So afaics Geany always chooses the "fast" type?
Geany does not use any of the various system mime type guessers to set filetype or mimetype, they are unreliable, and you can see the one you used gets more than one answer. Geany sets the filetype from specific content such as the shell shebang or from the extension to ensure its deterministic. And the mime type is set from that as above.
Version 1.37.1, the issue occurs on 2 Archlinux installations and someone using Geany on Debian Stable (Bunsenlabs) reports not having that issue.
Since "application/octet-stream" does not exist in Geany source, perhaps Arch is patching "text/plain" to that when they build the package, but Debian doesn't. The Geany project does not make packages, there are too many distros each with their own special rules, you would have to raise it with the Arch package maintainers.

I'm not a coder, but I'd be happy to get some help understanding, and possibly help resolve it.
