nyash-codex	acffd9974b	feat(phase31): Step 3-A/B - Add early return and structure checks to LoopToJoinLowerer ... Phase 31 Step 3-A: Add early return using is_case_a_minimal_target() filter - Check before LoopScopeShape construction for efficiency - Returns None immediately for non-target functions Phase 31 Step 3-B: Add structural validation to is_supported_case_a_loop() - Single exit check: loop_form.break_targets.len() <= 1 - Variable presence check: !carriers.is_empty() || !pinned.is_empty() - Debug logging for rejection reasons Also refactored lower_with_scope() from if-else chain to match expression for clarity. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>	2025-11-26 06:02:52 +09:00
