All I know is if I send a pdf file to my Kindle with the word "convert"
in the subject line (without the quotes), the file is converted to the
Kindle format. I gleaned this *astuce* sometime, somewhere, that has
since been forgotten.

I haven't performed this maneuver in a fairly long while, though, so
things may have changed. Sometimes you are required to run as fast as you
as you can in order to remain in the same place.

The file was indeed sent to my Kindle, and it didn't land as a PDF. I
can read it in the Kindle reader. The table of contents is a mess.
Tables are a mess.

I downloaded everything with the same base name as I sent -- a file and
a directory. LibreOffice can't read any of it. Calibre can't read any
of it, either in the download or in the mounted Kindle. "file" has no
idea what any of the files are.

You could try if Googles ML model "magika" can do a better job (available
via pypi). Otherwise, what exactly does "file" or better "file -i" say?
Worst case, you could open the files in a hex editor and google the first
few bits. Chances are the format uses "magic bits", so the first few bits
in hex are identical for all files of that format.

I think you missed that.

I didn't miss that. "file" will always tell you something, I doubt there
can be any situation where it will just give you an empty output. You
because it can get specific, it will tell you if something is a text file
or binary format it whatever. So what's the output?

If that isn't a start, I don't know what is. The JSON file can potentially
give an idea about what the other files do.

If you seek a solution that allows to get result in a single click then 
the following would not help.

I would not spent time trying to find a PDF to ePub converter. Almost 
certainly PDF generated by LaTeX is not friendly to them (yet?), it is 
for printing.

ePub is a bit special zip archive containing XHTML files that is why, I 
think, it is better to concentrate on LaTeX to HTML converters. Be ready 
to simplify macros used in your TeX files to make them compatible with a 
specific converter. I have never tried TeX4ht, but it may be a better 
option than rather old latex2html. Start from a simple document to 
identify what TeX macros causes issues with your book.

Almost certainly some tuning is required: styles, math representation. I 
have no idea, what is better for ePub: SVG or raster images, MathML. 
There is a number of converters to MathML with their specific shortcomings.

I expect that the following site actively uses TeX as original format:
https://dlmf.nist.gov/ NIST Digital Library of Mathematical Functions

If you do not use advanced LaTeX markup then it may be possible to 
convert it to Org mode https://orgmode.org/ with reasonable efforts. It 
may be converted to HTML using other tools. However some scripting 
(Emacs lisp or lua for pandoc) may be required to achieve decent quality 
of exported documents.

There are should be some blog posts describing troubles and workarounds.

Actually, magika does tell you quite well what you need to know. .yjf could
be something comparable to a JPEG, .kfx seems to be very similar to a BMP
image. .meta seems to be just a JSON text file. .mf could be too, but at
least it will be a text file. The rest is unknown binary data you'll
probably have no way of handling, they will be proprietary. But of course
you can still try the magic bit variant, maybe that can tell you if someone
was already able to write something to handle it.

This is indeed a regrettable outcome to a good-faith suggestion.

One is led to wonder at times why you technical (the term used quite
loosely in your case) people prove to be so often such intolerable
asswipes, but I'm not losing much sleep over it, though the higher
echelons of your generally uncultured ilk seem to be ruling what's left
of the world.

I'm sure, though, that the latter will continue on despite everything,
while the former will lie sooner or later permanently horizontal.

Have you completely lost it? You should leave this and any other mailing
lists before you are being sued and kicked out for what you write. And
trust me, this message of yours is more than enough reason for that.

I'm confident I'll be sued for your rudeness and ineptitude, and pass
the rest of my days in some prison devised in your tiny and
ineffectual mind.
