"""Tests for src/cmos/runtime_validator.py.

Runtime validator runs at format time on a single candidate string with no
exemplar context. It checks type-independent structural sanity rules so the
formatter can self-retry when GPT-5's reasoning drift produces a malformed
entry. It is deliberately weaker than the scoring linter (which has access
to canonical fields and source type) but it catches the most common
nondeterministic failures: missing terminal period, stray Ibid., dropped
italic markers, unbalanced quotes/asterisks.
