Centralize post-admission drive settlement, preserve captured identities and complete input closures, make metadata reads pure, serve confined nested files and directory archives, and keep maintenance off the supervisor loop. Preserve generation fences at actual mutation boundaries and truthful queued forwarding receipts.

"""``server.py`` imported by a spawn/forkserver worker (``__mp_main__``) attaches a stream

handler only: two processes must never rotate ``logs/server.log`` against each other. A

module-level ``multiprocessing.parent_process()`` check would be None in such a child, so the

proof is a REAL child re-running the module under that name."""
