You’re right to zoom in here, but I need to be very precise and honest with you, because this is one of those moments where bad tooling can quietly sabotage a good debugging instinct.

What you got back is not the full <code>cat</code> output of either file. The first file is truncated almost immediately after the helper functions, and the second file isn’t even shown from the top. That tells us something important: the environment is eliding large files in stdout, either by design or by buffer limits. So if you forward this to your senior as “raw output,” they’ll (correctly) say it’s incomplete and therefore useless.

That said, even the partial glimpse already hints at the real shape of the problem.

The start-server.sh script is a classic supervisor-friendly bootstrapper. set -eo pipefail means any non-zero exit kills the script. That’s good for correctness but brutal for resilience. If anything inside that script fails once—env var missing, port already bound, Python import error—the whole terminal server silently dies and gets restarted by supervisord. That alone can create “it connects but behaves weirdly” symptoms.

The server.py fragment you see confirms something more damning: this is a plain uvicorn app, not guarded by retries, not wrapped in a health loop, not protected against partial startup failure. If the app imports succeed but a late-bound resource (pipe, PTY, websocket, etc.) fails, uvicorn will still be up, sockets will still be open, and clients will connect into a half-functional service. That matches your symptoms far more than any OS-level issue.

Now the uncomfortable but necessary correction: if you want to “get to the bottom of this,” you must stop thinking in terms of files and start thinking in terms of control flow at startup. The bug you’re chasing is almost certainly one of these:
– an env var (HOST, PORT, auth token) being set differently between restarts
– a port collision that uvicorn doesn’t crash on but misroutes
– a subprocess / pipe cleanup error that leaves the server alive but broken
– supervisord restarting faster than logs flush, so you miss the real error

If you want, the next useful step is not more cat. It’s one of these, in order of brutality and clarity:
# dump the full file contents in chunks so nothing is elided
# run the server manually with set -x to watch it die
# capture uvicorn startup logs with --log-level debug
# strace the PID during startup if you’re really done being polite

Tell me which one you want. But don’t send partial code to your senior and ask them to divine the truth—they’ll just send you back to collect better evidence, which is exactly where you are now.
