task: aphoria-concept-paths created: 2026-02-06 phase: DEFERRED before_count: 29 current_count: 29 description: | Concept paths built inconsistently: - Pattern A: inline format! with concept_path.join("/") - 24 instances - Pattern B: build_claim() helper in traits.rs - exists but underused - Pattern C: format! with concept_prefix - 3 in llm/extractor.rs - Pattern D: test-only literals - scattered The build_claim() helper EXISTS but is underutilized. DEFERRED: Low priority - all patterns produce correct output. Fixing would require touching 24 extractors with no functional benefit. New extractors should use build_claim() per skill guidance. current: "DEFERRED" next: [] defer_reason: | 1. All current patterns work correctly 2. build_claim() helper exists for new code 3. Large refactor with no functional benefit 4. Skill already guides new extractors to use helper
