- Resolved `tmp_path_factory` exhaustion error in `conftest.py` isolation setup - Fixed aggressive string-replacement artifacts (`is_eval_close(..., True and ...)`) in contemplation and relational reader test modules that swallowed boolean precedence - Re-pinned Claude hybrid verification expected artifacts (scenarios 1-5) to correctly reflect their new geometry-derived trace hashes - Updated construction affordance invariants and tests to reflect the targeted promotion of `proportional_change.decrease_to_fraction` from diagnostic-only to serving-allowed
