"""Seed must CREATE, never overwrite. Reopening an app re-POSTs the inline
output.files snapshot, which lags behind whatever the agent last wrote to the
workspace on disk; seeding it back used to revert every edited file while the
agent's new files survived (edits looked half-reverted on the next export).
Path constants are module-level, so (like test_versions) we monkeypatch them
into a temp tree. seed_workspace is async; we drive it with asyncio.run from a
sync test so the suite's bare-async-skip doesn't quietly no-op these."""
