## Changes ### joinir-design-map.md - Added "Allocator SSOT (Phase 135)" section - Principle: All ValueId allocation via single allocator (ConditionContext.alloc_value) - Prohibited: Internal counters in ConditionLoweringBox/ExprLowerer - Reason: Collisions with JoinIR params (ValueId(1000+)) overwrite header PHI dst - Detection: --verify catches "Value %N defined multiple times" - Added "Boundary Injection SSA (Phase 135)" section - Principle: condition_bindings allow aliases, but injected Copy dst must be unique - Fail-Fast: Error on different sources to same dst - Reason: Breaks MIR SSA, causes undefined behavior in VM/LLVM - Added "Box Implementation Checklist" - 4-point checklist for Box implementation/changes - Covers: --verify, smoke tests, allocator usage, boundary injection ### CLAUDE.md - Organized "重要設計書" section with clearer structure - Added "JoinIR 設計図" subsection with both documents: - JoinIR アーキテクチャ概要 (normative SSOT for contracts/invariants) - JoinIR 設計マップ (navigation SSOT for implementation) - Grouped related documents: JoinIR, MIR・言語仕様 ## Context Phase 135 revealed that missing "what not to do" (invariants/contracts) in design docs led to Allocator SSOT violations and ValueId collisions. This update ensures future Box implementations can follow clear contracts. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
