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

- pattern3_with_if_phi.rs: dynamic single/multi-carrier handling
- ExitLine/CarrierVar.join_id: NO CHANGES NEEDED (existing infra worked!)
- YAGNI principle validated - PhiGroupBox was not necessary
Blocker discovered: Nested Select→Branch+Phi conversion bug
- JoinIR correctly generates: ValueId(20) = phi [(bb3, 14), (bb4, 18)]
- MIR incorrectly produces: %27 = phi [%28, bb8], [%32, bb9] (undefined)
- Root cause: joinir_block.rs Select expansion (bridge layer)
- NOT a Phase 195 issue - pre-existing bug in Select conversion
Phase 196 planned (NEW):

- 196-2: Formalize "1 Select = 3 blocks + 1 PHI" interface
- 196-3: Debug block reuse / block ID mapping

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

feat(joinir): Phase 183 LoopBodyLocal role separation
...
Implements role-based separation of LoopBodyLocal variables to prevent
inappropriate Trim promotion for body-only local variables.
## Changes
### Task 183-1: Design Documentation
- Created `phase183-loopbodylocal-role-separation.md` with role taxonomy:
- Condition LoopBodyLocal: Used in loop conditions → Trim promotion target
- Body-only LoopBodyLocal: Only in body → No promotion needed
- Documented architectural approach and implementation strategy
### Task 183-2: Implementation
- Added `TrimLoopLowerer::is_var_used_in_condition()` helper
- 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

feat(joinir): Phase 174 - JsonParser complex loop P5 extension design
...
- Task 174-1: Complex loop inventory (_parse_string/_parse_array/_parse_object)
- Analyzed remaining JsonParser loops for P5 expansion potential
- Identified _parse_string as most Trim-like structure (99% similarity)
- Documented complexity scores and minimization potential
- Task 174-2: Selected _parse_string as next P5 target (closest to Trim)
- Reason: LoopBodyLocal 'ch' usage matches Trim pattern exactly
- Structure: loop(pos < len) + substring + char comparison + break
- Minimization: Remove escape/buffer/continue → identical to Trim
- Task 174-3: Design doc for P5B extension (TrimLoopHelper reuse strategy)
- File: docs/development/current/main/phase174-jsonparser-p5b-design.md
- Strategy: Reuse existing TrimLoopHelper without modifications
- Proven: Pattern applies to any character comparison, not just whitespace
- Task 174-4: Minimal PoC (_parse_string without escape) successful
- Test: local_tests/test_jsonparser_parse_string_min.hako
- Result: [pattern2/trim] Safe Trim pattern detected ✅
- Detection: Trim with literals=['"'] (quote instead of whitespace)
- Routing: Added whitelist entries for JsonParserStringTest methods
- Task 174-5: Documentation updates
- Updated CURRENT_TASK.md with Phase 174 summary
- Updated joinir-architecture-overview.md with P5 generality proof
- Created phase174-jsonparser-loop-inventory-2.md (detailed analysis)
- Created phase174-jsonparser-p5b-design.md (implementation strategy)
Success Criteria Met:
✅ _parse_string minimized version runs on P5 pipeline
✅ TrimLoopHelper works with '"' (non-whitespace character)
✅ Proven: Trim pattern is character-comparison-generic, not whitespace-specific
✅ Two new design docs (inventory + design)
✅ Phase 175+ roadmap established (multi-carrier, escape sequences)
Technical Achievement:
The P5 Trim pipeline successfully handled a quote-detection loop with zero code changes,
proving the architecture's generality beyond whitespace trimming.

feat(joinir): Phase 172 - Trim pattern JoinIR lowering implementation
...
Implement actual MIR generation for Trim pattern loops, enabling
LoopBodyLocal variables to work through bool carrier promotion.
## Implementation (pattern2_with_break.rs)
- emit_whitespace_check(): Generate OR chain for whitespace comparison
- extract_substring_args(): Extract s, start from substring call
- Initial carrier generation: ch0 = s.substring(start, start+1)
- Whitespace check: is_ch_match0 = (ch0 == " " || "\t" || "\n" || "\r")
- ConditionEnv integration: Register carrier for JoinIR condition
- Break condition replacement: !is_ch_match instead of original ch checks
## Architecture
- Host MIR: substring calls, OR chain evaluation, BoxCall
- JoinIR: Only sees bool carrier for break control
- No new JoinIR instructions added
## Documentation
- phase172-trim-lowering-impl.md: Design and implementation details
- loop_pattern_space.md: Analysis of all loop pattern combinations
Test: Trim loops compile and generate JoinIR successfully
Build: 0 errors, clean compilation

feat(joinir): Phase 171-C-2 Trim pattern detection in LoopBodyCarrierPromoter
...
Implements the Trim pattern detection logic for carrier promotion:
- find_definition_in_body(): Iterative AST traversal to locate variable definitions
- is_substring_method_call(): Detects substring() method calls
- extract_equality_literals(): Extracts string literals from OR chains (ch == " " || ch == "\t")
- TrimPatternInfo: Captures detected pattern details for carrier promotion
This enables Pattern 5 to detect trim-style loops:
```hako
loop(start < end) {
local ch = s.substring(start, start+1)
if ch == " " || ch == "\t" || ch == "\n" || ch == "\r" {
start = start + 1
} else {
break
}
}
```
Unit tests cover:
- Simple and nested definition detection
- substring method call detection
- Single and chained equality literal extraction
- Full Trim pattern detection with 2-4 whitespace characters
