"""Shared pytest plumbing for both packages' suites.

/tmp on the dev box is a 4 GB tmpfs, and a full suite run writes ~1 GB of
fixture state there. Three times on 2026-08-09, concurrent suite runs filled
it and produced ``sqlite3.OperationalError: database or disk is full``
failures that read like data corruption. So: pytest's temp roots live under
the repo on real disk (gitignored), one directory per process so concurrent
agent runs never collide, swept after a day so retention cannot creep.

An explicit ``--basetemp`` still wins, untouched.

# A full-suite run leaves ~1 GB behind and agent sessions run many; a day of
# retention hit 44 GB on 2026-08-09 — twice, because the sweep window alone
# can't keep up with concurrent agents. So: a passing run deletes its own
# directory on exit (a failing one keeps it for debugging), and the sweep
# below is the backstop for crashed runs.
