Architect drift review surfaces:
- 2x [high]: rigid-var refinement misses type-unification leg
(refine_multi_candidate_residual filters declared constraints on
class only, breaks forall a b. Show a, Show b => ... shapes);
same-module bare-class qualifier Show.show unreachable because
qualifier_is_class_shape = q.contains('.') excludes the no-dot
case (contradicts mq.1 canonical-form symmetry).
- 2x [medium]: class-method-shadowed-by-fn warning over-fires on
locals shadowing prelude method names without
class-candidate-for-arg-type check; DESIGN.md Data Model schema
fragments don't carry the canonical-form rule for class-ref
fields (only the prose at 1156-1162 does).
- 1x [medium] acknowledged debt without fix: synth(...) grown to
10 mut-ref parameters — refactor cost disproportionate to gain.
- 2x [low] roadmap backlog: Trajectories B + D have unit-test
coverage only; collect_mono_targets rebuilds env without
active_declared_constraints (currently latent).
Bench: compile_check.py + cross_lang.py exit 0; check.py exit 1
across 4 consecutive re-runs with metric identity shifting
between runs — 5th-consecutive audit observation of the same
noise envelope. Baseline pristine.
Resolution: mq.tidy iter covers 4 actionable items; 3 deferred.
