- 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

"""ADR-0182 — cross-composer disagreement pooling (distractor refusal).
|
|
|
|
Two surfaces under test:
|
|
|
|
* :func:`generate.derivation.verify.classify_derivation` — the commit-eligibility
|
|
class (``complete`` / ``exempt`` / ``None``) and, critically, that the
|
|
isolated-foreign exemption is *narrow* (an empty-unit or same-unit unused
|
|
quantity is never exempt — it is real signal, not a distractor).
|
|
* :func:`generate.derivation.pool.resolve_pooled` — the pooled resolution: a clean
|
|
reading commits, a distractor problem's product-vs-additive disagreement refuses,
|
|
and (the wrong=0-critical property) an ``exempt``-only answer **never commits**.
|
|
|
|
Sealed lane: ``chat/`` does not import these; serving ``3/47/0`` cannot move.
