b92f85f993 refactor(mir): Remove TypeContext legacy fields (Phase 2-3/7) 
完全移行→削除の安全順序（Option C）に従い、TypeContext の
deprecated フィールドと sync helpers を完全削除。

⚠️ 危険ゾーン: TypeFactsBox 等の同名フィールドと混同しないよう、
ファイル単位で手作業移行を実施。

## Changes
- Migrated all MirBuilder access sites to type_ctx.* (manual, 40+ files)
- Removed 3 deprecated fields (value_types, value_kinds, value_origin_newbox)
- Removed 2 sync helpers (sync_type_ctx_to_legacy, sync_legacy_to_type_ctx)
- Verified TypeFactsBox, CalleeGuardBox unchanged (no false positives)

## Tests
- cargo test --release --lib: 1029/1033 PASS
- TypeFactsBox integration: PASS (borrowed references unchanged)
- Deprecation warnings: 456 → 255 (-201, -44%)

## Safety Verification
✅ TypeFactsBox unchanged (still uses &'a BTreeMap borrowed references)
✅ CalleeGuardBox unchanged
✅ CalleeResolverBox unchanged
✅ BoxCompilationContext unchanged

Phase 2 Progress: 3/7 contexts complete (43%)
- ✅ MetadataContext
- ✅ CoreContext
- ✅ TypeContext (this commit)

c8ad1dae65 feat(naming): Phase 21.7++ Phase 3 完全達成 - Builder 側 StaticMethodId SSOT 統一 
## 🎊 成果概要
**Phase 3: 全体統一** - MIR Builder 側を StaticMethodId 準拠に統一！

### ✅ 実装完了項目（全4タスク）
1. **素手 split 調査** (Phase 3.1)
   - 調査結果: known.rs に2箇所のみ（split_once）
   - unified_emitter には素手 split なし
   - 置き換え対象: 2箇所のみで簡潔

2. **unified_emitter.rs 統一** (Phase 3.2)
   - methodization 部分を StaticMethodId::parse() に変更
   - decode_static_method() → StaticMethodId::parse()
   - is_static_method_name() → StaticMethodId::parse().is_some()
   - arity 判定を Optional 対応（None も許容）

3. **known.rs split_once 置き換え** (Phase 3.3)
   - 2箇所の split_once('.') → StaticMethodId::parse()
   - box_name 取得を構造化表現経由に統一
   - コード削減: 8行 → 4行（50%削減）

4. **テスト実行・確認** (Phase 3.4)
   - json_lint_stringutils_min_vm: PASS ✅
   - namingbox_static_method_id: 13/13 PASS ✅
   - ビルド成功、警告のみ（既存問題）

### 📊 技術的効果
- **素手 split 根絶**: 全箇所を StaticMethodId 経由に統一
- **コード品質向上**: 構造化表現で型安全化
- **保守性向上**: 名前パース処理が SSOT に集約
- **後方互換**: 既存機能に影響なし

### 🎯 Phase 4 への準備完了
- Builder/VM 両方が StaticMethodId SSOT 準拠
- ドキュメント整備のみ残存（2-3時間）

---

**Phase 0**: ✅ 完了 (Silent Failure 根絶)
**Phase 1**: ✅ 完了 (SSOT 基盤確立)
**Phase 2**: ✅ 完了 (VM 統一)
**Phase 3**: ✅ 完了 (Builder 統一)
**Phase 4**: 次のタスク (ドキュメント化)

eadde8d1dd fix(mir/builder): use function-local ValueId throughout MIR builder 
Phase 25.1b: Complete SSA fix - eliminate all global ValueId usage in function contexts.

Root cause: ~75 locations throughout MIR builder were using global value
generator (self.value_gen.next()) instead of function-local allocator
(f.next_value_id()), causing SSA verification failures and runtime
"use of undefined value" errors.

Solution:
- Added next_value_id() helper that automatically chooses correct allocator
- Fixed 19 files with ~75 occurrences of ValueId allocation
- All function-context allocations now use function-local IDs

Files modified:
- src/mir/builder/utils.rs: Added next_value_id() helper, fixed 8 locations
- src/mir/builder/builder_calls.rs: 17 fixes
- src/mir/builder/ops.rs: 8 fixes
- src/mir/builder/stmts.rs: 7 fixes
- src/mir/builder/emission/constant.rs: 6 fixes
- src/mir/builder/rewrite/*.rs: 10 fixes
- + 13 other files

Verification:
- cargo build --release: SUCCESS
- Simple tests with NYASH_VM_VERIFY_MIR=1: Zero undefined errors
- Multi-parameter static methods: All working

Known remaining: ValueId(22) in Stage-B (separate issue to investigate)

dd65cf7e4c builder+vm: unify method calls via emit_unified_call; add RouterPolicy trace; finalize LocalSSA/BlockSchedule guards; docs + selfhost quickstart 
- Unify standard method calls to emit_unified_call; route via RouterPolicy and apply rewrite::{special,known} at a single entry.\n- Stabilize emit-time invariants: LocalSSA finalize + BlockSchedule PHI→Copy→Call ordering; metadata propagation on copies.\n- Known rewrite default ON (userbox only, strict guards) with opt-out flag NYASH_REWRITE_KNOWN_DEFAULT=0.\n- Expand TypeAnnotation whitelist (is_digit_char/is_hex_digit_char/is_alpha_char/Map.has).\n- Docs: unified-method-resolution design note; Quick Reference normalization note; selfhosting/quickstart.\n- Tools: add tools/selfhost_smoke.sh (dev-only).\n- Keep behavior unchanged for Unknown/core/user-instance via BoxCall fallback; all tests green (quick/integration).

510f4cf523 builder/vm: stabilize json_lint_vm under unified calls 
- Fix condition_fn resolution: Value call path + dev safety + stub injection
- VM bridge: handle Method::birth via BoxCall; ArrayBox push/get/length/set direct bridge
- Receiver safety: pin receiver in method_call_handlers to avoid undefined use across blocks
- Local vars: materialize on declaration (use init ValueId; void for uninit)
- Prefer legacy BoxCall for Array/Map/String/user boxes in emit_box_or_plugin_call (stability-first)
- Test runner: update LLVM hint to llvmlite harness (remove LLVM_SYS_180_PREFIX guidance)
- Docs/roadmap: update CURRENT_TASK with unified default-ON + guards

Note: NYASH_DEV_BIRTH_INJECT_BUILTINS=1 can re-enable builtin birth() injection during migration.
