feat(joinir): Phase 53 - SELFHOST-NORM-DEV-EXPAND implementation
...
Expanded selfhost dev Normalized target with 2 practical P2/P3 loop variations,
strengthened structural signature axis, and implemented two-stage detection.
Key Changes:

- Added Phase 53 section with candidate selection rationale
- Documented two-stage detector strategy (structural primary + dev-only name guard)
- Defined structural axis strengthening (carrier count/type, branch patterns)
2. Fixtures (+210 lines):
- selfhost_args_parse_p2.program.json (60 lines): P2 with String carrier + conditional branching
- selfhost_stmt_count_p3.program.json (150 lines): P3 with 5 carriers + multi-branch if-else
3. Structured Builders (fixtures.rs +48 lines):
- build_selfhost_args_parse_p2_structured_for_normalized_dev()
- build_selfhost_stmt_count_p3_structured_for_normalized_dev()
4. ShapeGuard Two-Stage Detection (shape_guard.rs +80 lines):

- Implemented is_selfhost_args_parse_p2(): P2 core family + name guard
- Implemented is_selfhost_stmt_count_p3(): 2-10 carrier check + name guard
- Updated capability_for_shape() mappings
5. Bridge Integration (bridge.rs +8 lines, normalized.rs +10 lines):

- Added roundtrip reconstruction handlers
6. Entry Point Registration (ast_lowerer/mod.rs +2 lines):
- Registered selfhost_args_parse_p2/selfhost_stmt_count_p3 as LoopFrontend routes
7. Dev VM Comparison Tests (normalized_joinir_min.rs +40 lines):
- normalized_selfhost_args_parse_p2_vm_bridge_direct_matches_structured()
- normalized_selfhost_stmt_count_p3_vm_bridge_direct_matches_structured()
8. Test Context Fix (dev_env.rs):
- Added thread-local test context depth counter
- Fixed deadlock in nested test_ctx() calls via reentrant with_dev_env_if_unset()
Structural Axis Growth:
P2 family:
- Carrier count: 1-3 (unchanged)
- NEW: Type diversity (Integer/String mixed)
- NEW: Conditional branching patterns (Eq-heavy comparisons)
P3 family:
- NEW: Carrier count upper bound: 2-10 (was 2-4)
- NEW: Multi-branch if-else (5+ branches with nested structure)
- NEW: Complex conditional patterns
Test Results:
- normalized_dev: 40/40 PASS (including 2 new tests)
- lib regression: 939 PASS, 56 ignored
- Existing behavior unchanged (normalized_dev feature-gated)
Phase 53 Achievements:
✅ P2/P3 each gained 1 practical variation (2 total)
✅ Two-stage detection: structural primary + dev-only name guard
✅ Structural axis expanded: 4 axes (carrier count/type/Compare/branch patterns)

✅ Test context deadlock fixed (0.04s for 29 tests)
Files Modified: 14 files
Lines Added: ~516 lines (net)
Implementation: Pure additive (feature-gated)
Next Phase (54+):
- Accumulate 6+ loops per P2/P3 family
- Achieve 5+ stable structural axes
- Target < 5% false positive rate
- Then shrink/remove name guard scope

docs(joinir): Phase 48 - Normalized P4 (Continue) design
...
Complete design documentation for Pattern4 (continue) Normalized support,
extending unified Normalized infrastructure to all 4 loop patterns.
Design documents:
- phase48-norm-p4-design.md: Complete P4 Normalized design (380 lines)
- Key insight: continue = immediate TailCallFn(loop_step, ...) (no new instruction!)
- Infrastructure reuse: 95%+ from P2/P3 (only ContinueCheck step kind new)
- Target loops prioritized:
- ◎ _parse_array (skip whitespace) - PRIMARY (Phase 48-A)
- ○ _parse_object (skip whitespace) - Extended
- △ _unescape_string, _parse_string - Later
- Control flow: ContinueCheck before Updates (skip processing early)
- Same EnvLayout/ConditionEnv/CarrierInfo/ExitLine as P2/P3
- Implementation strategy: dev-only → canonical (proven approach)
Architecture:
- Unified Normalized for P1/P2/P3/P4 (all patterns same pipeline)
- P4 uses loop_step(env, k_exit) skeleton (same as P2/P3)
- continue semantics: TailCallFn = skip to next iteration (CPS natural fit)
Benefits:
- 95% infrastructure reuse from P2/P3
- No new JpInst needed (continue = existing TailCallFn)
- Incremental rollout (dev → canonical)
- Clear semantic: continue = immediate recursion
Implementation roadmap:
- Phase 48-A: Minimal continue (dev-only)
- Phase 48-B: Extended patterns (multi-carrier)
- Phase 48-C: Canonical promotion
Updates:
- joinir-architecture-overview.md: Added Phase 48 section
- CURRENT_TASK.md: Phase 48 entry (Design Complete)
- phase47-norm-p3-design.md: Minor formatting
Status: Design phase complete (doc-only, no implementation yet)

docs(joinir): Phase 47 - Normalized P3 (If-Sum) design
...
Complete design for extending Normalized JoinIR to Pattern3 (if-sum) loops,
reusing 90% of existing P2 infrastructure.
Key insight: P3 already uses P2's Structured JoinIR foundation (Phase 220
ConditionEnv integration), so Normalized extension is straightforward.
Design documents:
- phase47-norm-p3-design.md: Complete P3 Normalized design
- Infrastructure reuse analysis (ConditionEnv, CarrierInfo, ExitLine)
- Representative loops identified (phase212_if_sum_min primary target)
- StepScheduleBox extension (IfCond, ThenUpdates, ElseUpdates)
- JpInst reuse (If instruction already exists)
- Implementation strategy (dev-only → canonical)
- File impact estimate (~365 lines, pure additive)
- phase47-test-files-inventory.md: P3 test file catalog
- 3 P3 test files analyzed
- phase212_if_sum_min.hako: Single carrier (PRIMARY)
- phase217_if_sum_multi_min.hako: Multi-carrier (sum + count)
- phase218_json_if_sum_min.hako: Variable accumulation (sum + i)
Architecture:
- Unified Normalized for P1/P2/P3 (same pipeline)
- Conditional updates only difference vs P2
- No P2 code changes needed (pure additive)
Benefits:
- 90% infrastructure reuse from P2
- Proven incremental rollout (dev → canonical)
- Clear path to P4 (continue pattern)
Implementation roadmap:
- Phase 47-A: Minimal sum_count (dev-only)
- Phase 47-B: array_filter (body-local + method calls)
- Phase 47-C: Canonical promotion
Updates:
- joinir-architecture-overview.md: Added Phase 47 section
- CURRENT_TASK.md: Updated Phase 47 entry (Design Complete)
Status: Design phase complete, ready for implementation

feat(joinir): Phase 46 - P2-Mid canonical Normalized promotion
...
Promote P2-Mid patterns (_atoi real, _parse_number real) to canonical
Normalized→MIR(direct) route, completing P2 line transition.
Canonical set expansion (Phase 41 → Phase 46):
- P2-Core: Pattern2Mini, skip_ws mini/real, atoi mini
- P2-Mid: atoi real, parse_number real (NEW)
All JsonParser P2 loops (_skip_whitespace, _atoi, _parse_number) now
canonical Normalized - Structured→MIR is legacy/comparison-only.
Key changes:
- shape_guard.rs: Expanded is_canonical_shape() (+2 patterns)
- JsonparserAtoiReal
- JsonparserParseNumberReal
- Made NormalizedDevShape enum public
- bridge.rs: Updated canonical routing comments (Phase 41 → 46)
- normalized.rs: Made shape_guard module public
- normalized_joinir_min.rs: Added Phase 46 canonical verification test
- phase46-norm-canon-p2-mid.md: Complete design documentation
Out of scope (deferred):

- Selfhost complex loops → separate phases
Benefits:
- Clear P2 boundary: All JsonParser P2 = Normalized canonical
- Infrastructure validation: Phase 43/245B proven production-ready
- Simplified mental model: P2 = Normalized-first, P3/P4 = future
Tests: 937/937 PASS (lib), 20/20 PASS (normalized_dev feature)

feat(joinir): Phase 223-3 - LoopBodyCondPromoter implementation
...
Implements LoopBodyLocal condition promotion for Pattern4/continue patterns.
Previously, loops with LoopBodyLocal in conditions would Fail-Fast.
Now, safe Trim/skip_whitespace patterns (Category A-3) are promoted and lowering continues.
## Implementation
- **LoopBodyCondPromoter Box** (loop_body_cond_promoter.rs)
- extract_continue_condition(): Extract if-condition from continue branches
- try_promote_for_condition(): Thin wrapper delegating to LoopBodyCarrierPromoter
- ConditionPromotionRequest/Result API for Pattern2/4 integration
- **Pattern4 Integration** (pattern4_with_continue.rs)
- Analyze both header condition + continue condition
- On promotion success: merge carrier_info → continue lowering
- On promotion failure: Fail-Fast with clear error message
- **Unit Tests** (5 tests, all PASS)
- test_cond_promoter_skip_whitespace_pattern
- test_cond_promoter_break_condition
- test_cond_promoter_non_substring_pattern
- test_cond_promoter_no_scope_shape
- test_cond_promoter_no_body_locals
- **E2E Test** (phase223_p4_skip_whitespace_min.hako)
- Category A-3 pattern: local ch = s.substring(...); if ch == " " { continue }
- Verifies promotion succeeds and Pattern4 lowering proceeds
## Documentation
- joinir-architecture-overview.md: Updated LoopBodyCondPromoter section (Phase 223-3 完了)
- CURRENT_TASK.md: Added Phase 223-3 completion summary
- PHASE_223_SUMMARY.md: Phase overview and status tracking
- phase223-loopbodylocal-condition-*.md: Design docs and inventory
## Achievement
- **Before**: LoopBodyLocal in condition → Fail-Fast
- **Now**: Trim/skip_whitespace patterns promoted → Pattern4 lowering continues
- **Remaining**: Phase 172+ JoinIR Trim lowering for complete RC correctness

docs(joinir): Phase 218 JsonParser if-sum investigation complete
...
Completes Phase 218 investigation: Identifies root cause preventing
AST-based if-sum lowerer from activating.
## Investigation Summary
### Test Case Created
- File: apps/tests/phase218_json_if_sum_min.hako
- Pattern: JsonParser-style conditional accumulation (sum = sum + i)
- Expected: RC=10, Actual: RC=0 (blocked by phantom carrier)
### Root Cause Identified: Phantom Carrier Bug
**Problem**: AST-based if-sum lowerer (Phase 213) never activates
**Cause Chain**:
1. loop_update_summary.rs uses name-based heuristics
2. Detects phantom "count" variable (doesn't exist in code)
3. counter_count() returns 2 instead of 1 (i + phantom "count")
4. is_simple_if_sum_pattern() returns false
5. Dual-mode dispatch uses legacy fallback instead of AST lowerer
**Evidence**:
```
Debug output shows hardcoded template "i % 2 == 1" (legacy lowerer)
Not from AST extraction (AST-based lowerer never called)
```
### Critical Discovery
**Phase 216 claim "RC=2 ✅ " for phase212_if_sum_min.hako is false**
- Current execution: RC=0 (wrong)
- Expected: RC=2
- Indicates: Phase 213-217 "success" was actually legacy lowerer
### Documentation Gap
Phase 216/217 tests may not have been executed correctly, or regression
occurred. All "if-sum" patterns are currently broken due to phantom
carrier detection blocking AST lowerer activation.
## Files Created
1. apps/tests/phase218_json_if_sum_min.hako - Test case
2. docs/development/current/main/phase218-jsonparser-if-sum-min.md - Investigation report
## Files Updated
1. CURRENT_TASK.md - Phase 218 investigation results
2. joinir-architecture-overview.md - Phase 218 entry
## Next Steps: Phase 219
**Target**: Fix phantom carrier detection in loop_update_summary.rs
**Fix**: Remove name-based heuristics, use assignment-based detection only
**Expected Result**: Both phase212 and phase218 tests pass with correct RC
## Lessons Learned
1. Documentation can become stale - verify test results
2. Silent fallbacks hide bugs - dual-mode needs clear activation logging
3. Name heuristics are fragile - prefer structural analysis

docs: Phase 195 Pattern 3 extension design (multi-carrier support)
...
Phase 195 design document for P3 (If-Else PHI) multi-carrier expansion:
- Goal: Handle 2-3 carriers in if-else branches simultaneously
- Scope: if-complete multi-carrier updates (flag+buffer, sum+count patterns)
Task breakdown:
- 195-1: Loop inventory (_parse_string simple, if-sum patterns)
- 195-2: LoopUpdateSummary/CarrierInfo design (multi-carrier support)
- 195-3: Pattern3 lowerer design (PhiGroup vs ExitLine extension)
- 195-4: Implementation scope (2-3 carriers, existing UpdateKind range)
- 195-5: Documentation updates (CURRENT_TASK.md + overview)
Design decisions:
- ✅ ExitLine extension (no PhiGroupBox - YAGNI principle)
- ✅ Both-branch carrier definition check (unchanged = use previous value)
- ❌ No ConditionEnv expansion (Phase 200+ deferred)
- ❌ LoopBodyLocal + MethodCall mix deferred to Phase 195+
Target loops:
1. JsonParser _parse_string (escaped flag + buffer)
- Carrier 1: escaped (BoolFlag) - conditional flag
- Carrier 2: buffer (StringAppend) - else-only update
2. selfhost if-sum (sum + count)
- Carrier 1: sum (NumberAccumulation) - then-only update
- Carrier 2: count (CounterLike) - then-only update
Test cases designed:
- phase195_flag_buffer.hako (BoolFlag + StringAppend)
- phase195_sum_count.hako (NumberAccumulation + CounterLike)
Expected outcome:
- phase195-pattern3-extension-design.md (complete design spec)
- Clear implementation scope for Phase 195-impl
- Path to 40% → 60% JsonParser coverage

feat(joinir): Phase 184 - Body-local MIR Lowering Infrastructure
...
Phase 184 implements the foundation for body-local variable support in
update expressions, completing the three-box architecture:
LoopBodyLocalEnv (storage), UpdateEnv (composition), and
CarrierUpdateEmitter (emission).
## Implementation Summary
### Task 184-1: Design Document
- Created phase184-body-local-mir-lowering.md
- Two-Environment System design (ConditionEnv + LoopBodyLocalEnv)
- Box-First design principles documented
### Task 184-2: LoopBodyLocalEnv Implementation
- New file: src/mir/join_ir/lowering/loop_body_local_env.rs (216 lines)
- Storage box for body-local variable name → ValueId mappings
- BTreeMap for deterministic ordering (PHI consistency)
- 7 unit tests: empty env, single/multiple locals, get/contains, iteration
### Task 184-3: UpdateEnv Implementation
- New file: src/mir/join_ir/lowering/update_env.rs (237 lines)
- Composition box for unified variable resolution
- Priority order: ConditionEnv (condition vars) → LoopBodyLocalEnv (body-local)
- 8 unit tests: priority, fallback, not found, combined lookup
### Task 184-4: CarrierUpdateEmitter Integration
- Modified: src/mir/join_ir/lowering/carrier_update_emitter.rs
- Added emit_carrier_update_with_env() (UpdateEnv version)
- Kept emit_carrier_update() for backward compatibility
- 4 new unit tests: body-local variable, priority, not found, const update
- Total 10 tests PASS (6 existing + 4 new)
### Task 184-5: Representative Test Cases
- apps/tests/phase184_body_local_update.hako (Pattern1 baseline)
- apps/tests/phase184_body_local_with_break.hako (Pattern2, Phase 185 target)
### Task 184-6: Documentation Updates
- Updated: docs/development/current/main/joinir-architecture-overview.md
- Updated: CURRENT_TASK.md (Phase 184 completion record)
## Test Results
All 25 unit tests PASS:
- LoopBodyLocalEnv: 7 tests
- UpdateEnv: 8 tests
- CarrierUpdateEmitter: 10 tests (6 existing + 4 new)
Build: ✅ Success (0 errors)
## Design Constraints
Following 箱理論 (Box Theory) principles:
- Single Responsibility: Each box has one clear purpose
- Deterministic: BTreeMap ensures consistent ordering
- Conservative: Pattern5 (Trim) integration deferred to Phase 185
- Fail-Fast: Explicit errors for unsupported patterns
## Scope Limitation
Phase 184 provides the **infrastructure only**:
- ✅ Storage box (LoopBodyLocalEnv)
- ✅ Composition box (UpdateEnv)
- ✅ Emission support (CarrierUpdateEmitter)
- ❌ Pattern2/4 integration (requires body-local collection, Phase 185)
## Next Steps
Phase 185: Pattern2/4 Integration
- Integrate LoopBodyLocalEnv into Pattern2/4 lowerers
- Add body-local variable collection from loop body AST
- Enable full E2E body-local variable support in update expressions

- Recursively checks if variable appears in condition AST
- Handles BinaryOp, UnaryOp, MethodCall node types
- Updated `try_lower_trim_like_loop()` to filter condition LoopBodyLocal
- Only processes LoopBodyLocal that appear in break conditions
- Skips body-only LoopBodyLocal (returns Ok(None) early)
- Added 5 unit tests for variable detection logic
### Task 183-3: Test Files
- Created `phase183_body_only_loopbodylocal.hako`
- Demonstrates body-only LoopBodyLocal (`temp`) not triggering Trim
- Verified trace output: "No LoopBodyLocal detected, skipping Trim lowering"
- Created additional test files (phase183_p1_match_literal, phase183_p2_atoi, phase183_p2_parse_number)
### Task 183-4: Documentation Updates
- Updated `joinir-architecture-overview.md` with Phase 183 results
- Updated `CURRENT_TASK.md` with Phase 183 completion status
## Results
✅ LoopBodyLocal role separation complete
✅ Body-only LoopBodyLocal skips Trim promotion
✅ 5 unit tests passing
✅ Trace verification successful
## Next Steps (Phase 184+)
- Body-local variable MIR lowering support
- String concatenation filter relaxation
- Full _parse_number/_atoi implementation

docs(joinir): Phase 182-6 Update documentation with P1/P2 verification results
...
Phase 182 Summary:
✅ Pattern1 (Simple) verification complete
✅ Pattern2 (Break) verification complete with integer operations
✅ Routing whitelist updated (_parse_number/2, _atoi/1, _match_literal/3)
✅ Representative tests created and passing
Blockers identified:
1. LoopBodyLocal variable handling
- Current: Tries Trim-specific carrier promotion (fails)
- Needed: Allow pure local variables (no promotion) in P1/P2
2. String concatenation filter (Phase 178)
- Current: Rejects 'num_str = num_str + ch' conservatively
- Needed: Gradual enablement for JsonParser use cases
Updated documentation:
- joinir-architecture-overview.md: Added Phase 182 status to JsonParser section
- CURRENT_TASK.md: Added Phase 182 completion and Phase 183 next steps
- phase182-simple-loops-design.md: Design memo for Phase 182
