"""Tests for memlog.py. Run: uv run --with pytest pytest scripts/tests/test_memlog.py
The spine under test is the flat, append-only, chronological invariant: every entry is
one line recorded at the end in the order it happened — no sections, no grouping, and no
lifecycle status the log would have to mutate.
