Tramp in its regular mode tries to filter out ansi colors. I have no

Solved it.
Your comment there reminded me of the commands I was checking earlier:
cd /home/jammy/project/ && exec <<'c03eae69968a16e9389e28c6627d55b2'
env PS1\=/jam\:jam-zevem\:/home/jammy/project/\ \#\$\
INSIDE_EMACS\=31.0.50\,compile\,tramp\:2.8.0-pre PAGER\= /bin/bash
(
zig build run
) </dev/tty
Tramp will be additionally setting TERM=dumb there won't it?
In any case I misunderstood how comint works based on your comment above
too. It can only parse basic escape codes; it wants "naked" text.
I traced a bunch of comint functions and I see this:

If I set TERM=dumb or manually invoke project compile with `zig build
--color off run` instead it all works as expected.
So I should either have that flag passed every time, else I need a way
to add TERM=dumb in a direct-async command.
