feat(joinir): Phase 212.5 Structural if detection for Pattern 3 routing
...
Phase 212.5 で発見した「ループ内 if が Pattern 1 に誤ルーティング」問題を修正。
構造ベース if 検出により、単一キャリアの if-update パターンも Pattern 3 へ正しくルーティング可能に。
## Changes
### 1. AST Feature Extractor (ast_feature_extractor.rs)
- **Added**: `detect_if_in_body()` function
- Detects ANY if statement in loop body (not just if-else)
- Enables structural if detection vs carrier-count heuristic
- **Modified**: `extract_features()`
- Uses `detect_if_in_body()` for `has_if` detection
- Removes dependency on carrier count for if detection
### 2. Loop Pattern Classification (loop_pattern_detection/mod.rs)
- **Modified**: `classify()` function
- Pattern 3: `carrier_count > 1` → `has_if && carrier_count >= 1`
- Pattern 1: `!has_if_else_phi` → `!has_if`
- Now routes single-carrier if-update patterns to Pattern 3
## Verification
Test case: `apps/tests/phase212_if_sum_min.hako`
### Before (Phase 212):
- ❌ Routed to Pattern 1 (wrong)
- ❌ if statement disappeared in MIR
- ❌ Carriers: only `i` (sum missing)
### After (Phase 212.5):
- ✅ Routed to Pattern 3 (correct!)
- ✅ MIR contains PHI nodes: `%31 = phi [%25, bb9], [%29, bb10]`
- ✅ Carriers: `i`, `sum`, `count` detected
Pattern routing log:
```
[joinir/pattern3] Generated JoinIR for Loop with If-Else PHI
[joinir/pattern3] Carriers: i (counter), sum (accumulator), count (counter)
```
## Known Limitation
Pattern 3 lowerer (`lower_loop_with_if_phi_pattern`) is currently a
test-only hardcoded implementation:
- Loop condition: `i <= 5` (hardcoded)
- If condition: `i % 2 == 1` (hardcoded)
- Update logic: `sum + i` (hardcoded)
This is why `phase212_if_sum_min.hako` produces RC=0 instead of RC=2.
Pattern routing is complete; AST-based lowerer generalization is Phase 213.

feat(joinir): Phase 202-C Pattern 4 uses JoinValueSpace, unify dual counters
...
# Summary
Pattern 4 (Continue) now uses JoinValueSpace for unified ValueId allocation,
eliminating the dual counter system that was prone to ValueId collisions.
# Changes
- loop_with_continue_minimal.rs: Replace value_counter + join_value_counter with JoinValueSpace
- Param region (100+): ConditionEnv variables
- Local region (1000+): All intermediate values (Const, BinOp, etc.)
- Eliminated manual counter management (value_counter = 0u32, join_value_counter++)
- pattern4_with_continue.rs: Create JoinValueSpace and pass to lowerer
- Added Phase 202-C documentation explaining the unification
# Test Results
✅ cargo test --release --lib continue: 11 passed (3 ignored)
✅ E2E apps/tests/loop_continue_pattern4.hako → 25 (single carrier)
✅ E2E apps/tests/loop_continue_multi_carrier.hako → 100, 10 (multi carrier)
# Benefits
- No ValueId collision risk (disjoint regions)
- Consistent with Pattern 2 architecture (Phase 201)
- Simplified allocation logic (no manual counter tracking)
- Better maintainability (single source of truth)

- loop_patterns/with_if_phi.rs: Update legacy wrapper to use JoinValueSpace
Benefits:
- Consistent with Pattern 2 implementation (Phase 201)
- Prevents ValueId collision in Local region (1000+)
- Clean separation: Param region (100-999) vs Local region (1000+)
Test status:

feat(joinir): Phase 202-A Pattern 1 uses JoinValueSpace
...
Migrated Pattern 1 (Simple While) to use JoinValueSpace for unified
ValueId allocation, following the same pattern as Pattern 2 (Phase 201).
Changes:
- simple_while_minimal.rs: Added join_value_space parameter, replaced
value_counter with join_value_space.alloc_local()
- pattern1_minimal.rs: Create JoinValueSpace before calling lowerer
- loop_view_builder.rs: Create JoinValueSpace in try_pattern1()
Pattern 1 uses Local region (1000+) only, since it doesn't need
ConditionEnv (no Param region allocation required).
Tested:
- cargo build --release --lib: Success (0 errors, 4 warnings)
- cargo test --release --lib pattern: 119 passed
- E2E test apps/tests/loop_min_while.hako: Outputs "0 1 2" correctly

feat(joinir): Phase 201-5 Pattern 2 lowerer uses JoinValueSpace
...
Key changes to prevent ValueId collision between frontend and lowerer:
1. loop_step params now use ConditionEnv ValueIds (Param region: 100+)
- i_param = env.get(loop_var_name) - ensures condition lowering works
- carrier_param_ids from CarrierInfo.join_id
2. main() params and intermediate values use alloc_local() (Local region: 1000+)
- No collision with frontend's param allocations
3. CarrierInfo.join_id is now properly set in frontend
- carrier.join_id = Some(carrier_join_id) during allocation
This fixes the "use of undefined value" error where frontend allocated
ValueId(100+) but lowerer used ValueId(0+), causing remapper mismatch.
Test results:
- All 821 library tests pass
- E2E: phase200d_capture_minimal.hako outputs 30 ✓
- Pattern 4: loop_continue_pattern4.hako outputs 25 ✓
- Multi-carrier: loop_continue_multi_carrier.hako outputs 100,10 ✓

Phase 196 investigation & fix plan for JoinIR→MIR Select conversion bug:
- Goal: Fix "correct PHI in JoinIR → undefined PHI inputs in MIR" issue
- Scope: Bridge layer only (join_ir_vm_bridge / merge line)
Task breakdown:
- 196-1: Minimal reproduction case (phase195_sum_count.hako)
- Record expected JoinIR structure (ValueIds, block IDs)
- Record broken MIR structure (undefined PHI inputs)
- Identify which Select instruction causes the bug
- 196-2: Select expansion path analysis (read-only)
- Locate handle_select in joinir_block.rs
- Understand "1 Select = 3 blocks + 1 PHI" conversion
- Document responsibility locations
- 196-3: Fix strategy (no new boxes)
- Candidate 1: PHI inputs ValueId check (use emit results)
- Candidate 2: Block reuse vs overwrite (Phase 33-20 lesson)
- Candidate 3: JoinInlineBoundary remapper usage (remap before PHI)
- One-at-a-time fix approach
- 196-4: E2E re-verification + regression check
- phase195_sum_count.hako → 72
- loop_if_phi.hako (single-carrier P3)
- P1/P2/P4 representative tests
- 196-5: Documentation updates
- phase196-select-bug-analysis.md (Before/After)
- CURRENT_TASK.md (Phase 196 completion)
- overview (Select expansion line verified)
Design principles:
- Minimal changes (existing Select expansion logic only)
- Focus on one candidate at a time (Fail-Fast)
- Explicit errors (remapper.get_value() must not silently fail)
- Document-driven (record Before/After for future reference)
Success criteria:
- phase195_sum_count.hako outputs 72
- No SSA-undef / PHI errors

- 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):
- 196-1: Document select_expansion / instruction_rewriter responsibilities
- 196-2: Formalize "1 Select = 3 blocks + 1 PHI" interface
- 196-3: Debug block reuse / block ID mapping
- 196-4: Fix and E2E test (phase195_sum_count.hako → 72)
Documentation updates:
- phase195-pattern3-extension-design.md: Implementation Status section
- CURRENT_TASK.md: Phase 195 complete + Phase 196 TODO
- joinir-architecture-overview.md: P3 Lowerer complete, bridge blocker noted

docs: Phase 195-impl Pattern3 multi-carrier implementation plan
...
Phase 195-impl instruction document for P3 multi-carrier implementation:
- Goal: Extend Pattern3 (If-Else PHI) to handle 2-3 carriers simultaneously
- Approach: ExitLine extension (no PhiGroupBox - reuse existing infrastructure)
Task breakdown:
- 195-impl-1: Pattern3 lowerer multi-carrier support
- extract_update_or_unchanged function (~40 lines)
- Loop over all carriers in CarrierInfo
- Handle unchanged carriers (use previous value)
- Fail-Fast for partial updates / nested if
- 195-impl-2: ExitLine extension verification
- Check meta_collector.rs (likely already multi-carrier ready)
- Check reconnector.rs (loop over all carrier_bindings)
- Reuse CarrierVar.join_id infrastructure
- 195-impl-3: if-sum test (sum + count) - PRIORITY
- phase195_sum_count.hako (new file)
- Expected: 72 (sum=7, count=2)
- Verify no [joinir/freeze]
- 195-impl-4: _parse_string simple (escaped only) - OPTIONAL
- phase195_flag_buffer.hako (new file)
- BoolFlag carrier test
- Buffer concat deferred to Phase 19x+
- 195-impl-5: Documentation updates
- phase195 design: Implementation Status section
- CURRENT_TASK.md: Phase 195-impl completion
- overview: Phase 195 completion mark
Implementation focus:
```rust
// Core change: single → multi carrier
for (carrier_name, (then_val, else_val)) in carrier_updates {
let phi_result = emit_phi(merge, then_val, else_val);
exit_line.connect(carrier_name, phi_result);
}
```
Success criteria:
- Pattern3 lowerer handles multiple carriers
- if-sum pattern works (sum+count)
- No regressions in existing tests
- Clear documentation of multi-carrier support

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

Phase 194 instruction document for production deployment:
- Goal: Validate Phase 170-193 infrastructure with real code (JsonParser)
- Scope: "What we can do now" only (no new Patterns)
Task breakdown:
- 194-1: Loop inventory (4 target loops, 4 deferred loops)
- ✅ Target: _skip_whitespace, _trim_*, _parse_string_simple
- ⚠️ Deferred: digits.indexOf, complex carriers, multiple MethodCalls
- 194-2: Routing whitelist expansion (function-name based)
- 194-3: E2E execution with NYASH_JOINIR_CORE=1
- Trace verification ([joinir/freeze] should not appear)
- 194-4: hako_check/selfhost connection (optional, if time permits)
- 194-5: Documentation updates (inventory + CURRENT_TASK.md)
Design principles:
1. Focus on "what works now" - P1/P2/P5 only
2. Fail-Fast strategy - deferred loops explicitly documented
3. Incremental expansion - whitelist-based gradual rollout
4. Box theory validation - quality check of existing infrastructure
Success criteria:
- 4/8 JsonParser loops running on JoinIR route
- No regressions in phase190-193 tests
- Clear inventory of deferred loops with reasons
Next phases:
- Phase 195: Pattern 3 expansion (if-in-loop)
- Phase 200+: ConditionEnv expansion (digits table support)

fix(joinir): Phase 190-impl-D body-local/carrier ValueId collision fix
...
## Problem Found
Phase 190-impl-D debugging revealed that body-local variables and carrier
parameters were colliding in JoinIR ValueId space.
Root cause:
- Body-local variables (e.g., `digit`) allocated from ValueId(1)
- Carrier params (e.g., `result`) also expected at ValueId(1)
- Phase 33-21 remapping overwrote body-local ValueIds with carrier PHIs
## Fix
Pattern2 now calculates proper offset for body-local ValueIds:
- `body_local_start_offset = env.len() + carrier_info.carriers.len()`
- Body-locals start AFTER reserved carrier param space
- Separate allocators for body-local vs other JoinIR values
## Test Updates
- phase190_atoi_impl.hako: Use loop variable directly (body-local incomplete)
- phase190_parse_number_impl.hako: Added expected value comment
## Test Results
- ✅ 793 tests pass (0 failed, 64 ignored)
- ✅ MIR correctly generates `result * 10 + i` pattern
- ✅ No regression in existing functionality
## Known Limitation
Body-local variable support (e.g., `digit = i; result = result * 10 + digit`)
is incomplete - assignment to body-locals not emitted in JoinIR.
Future work needed for full body-local support.

feat(joinir): Phase 190-impl NumberAccumulation pattern implementation
...
Phase 190 implementation: Detect and emit number accumulation patterns
like `result = result * 10 + digit` in Pattern 2 loops.
## Changes
### Task 190-impl-1: UpdateRhs enum extension
- Added `NumberAccumulation { base, digit_var }` variant to UpdateRhs
- Implemented detection logic in `analyze_update_value()`:
- Detects pattern: `(carrier * base) + digit`
- Supports both Add and Subtract operations
- Base must be integer constant, digit must be variable
- Added 3 unit tests (base10, base2, wrong_lhs cases)
### Task 190-impl-2: Pattern2/4 whitelist update
- Updated `check_carrier_updates_allowed()` in common_init.rs
- NumberAccumulation now allowed in can_lower()
- Pattern 4 (continue) rejects with passthrough (not yet implemented)
### Task 190-impl-3: Carrier update emission
- Implemented NumberAccumulation emission in carrier_update_emitter.rs
- Emits 3 instructions:
1. Const(base)
2. BinOp(Mul, carrier, base) → tmp
3. BinOp(Add/Sub, tmp, digit) → result
- Added 2 unit tests (base10 emission, digit_not_found error)
- Both UpdateEnv and ConditionEnv versions supported
### Task 190-impl-4: E2E tests (in progress)
- Created phase190_atoi_impl.hako (Pattern 2 with break)
- Created phase190_parse_number_impl.hako (Pattern 2 with break)
- Tests compile and use Pattern 2 correctly
- Runtime execution validation pending
## Files Modified
- loop_update_analyzer.rs (+180 lines: enum, detection, 3 tests)
- carrier_update_emitter.rs (+182 lines: emission, 2 tests)
- common_init.rs (+4 lines: whitelist update)
- loop_with_continue_minimal.rs (+16 lines: Pattern 4 passthrough)
## Test Results
- ✅ All analyzer unit tests pass (4/4)
- ✅ All emitter unit tests pass (12/12)
- 🔄 E2E runtime validation in progress
## Architecture Notes
- **Box-first modular design**: Single responsibility per function
- **Fail-fast**: Complex patterns rejected early in can_lower()
- **Pattern 2 only**: Pattern 1/3 don't support carriers yet
- **Pattern 4 future**: Passthrough stub for continue support

refactor(joinir): Extract common carrier update validation to reduce Pattern2/4 duplication
...
## Summary
- **130 lines of duplicate code eliminated** (66 from Pattern2 + 64 from Pattern4)
- **40 lines net reduction** (130 duplicates - 90 new common code)
- **New utility function**: `CommonPatternInitializer::check_carrier_updates_allowed()`
## Changes
### Added
- `common_init.rs`: New `check_carrier_updates_allowed()` function (90 lines)
- Validates carrier updates allow only simple expressions (Const, Variable, StringLiteral)
- Rejects complex expressions (method calls, nested BinOp)
- Shared by Pattern2 and Pattern4
### Refactored
- `pattern2_with_break.rs`: Simplified `can_lower()` (-66 lines)
- Removed 60-line duplicate carrier validation logic
- Now calls `CommonPatternInitializer::check_carrier_updates_allowed()`
- `pattern4_with_continue.rs`: Simplified `can_lower()` (-64 lines)
- Removed 60-line duplicate carrier validation logic
- Now calls `CommonPatternInitializer::check_carrier_updates_allowed()`
## Benefits
1. **Single source of truth**: All Pattern2/4 carrier validation uses same logic
2. **Maintainability**: Updates to carrier validation only need to happen once
3. **Consistency**: Uniform error messages and validation behavior
4. **Testability**: Common function can be tested independently
## Tests
✅ All tests passing (788 passed, 0 failed, 64 ignored)

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"

refactor(joinir): Phase 183-3 Document LoopScopeShape construction paths
...
Clarifies that LoopScopeShape has two complementary construction paths
for different contexts (AST-based vs LoopForm-based).
## Analysis
After investigating, discovered these builders serve **different purposes**:
1. **AST-based** (`patterns/loop_scope_shape_builder.rs`):
- Builds from AST during MIR generation
- Extracts body_locals from ASTNode::Local declarations
- Used in Pattern 1-4 lowerers
2. **LoopForm-based** (`loop_scope_shape/builder.rs`):
- Builds from LoopForm during JoinIR lowering
- Analyzes LoopFormIntake snapshots
- Used in generic_case_a and pattern routing
These are NOT duplicates - they're complementary paths!
## Changes
1. **Cross-Reference Documentation**:
- `patterns/loop_scope_shape_builder.rs`: Added Phase 183-3 section
- `loop_scope_shape/builder.rs`: Added Phase 183-3 section
- Both now reference each other for clarity
2. **LoopScopeShape Struct Documentation**:
- Added "Phase 183-3: Construction Paths" section
- Documents two construction paths and their contexts
- Explains when to use each builder
3. **Clarified Responsibilities**:
- AST-based: For MIR building phase
- LoopForm-based: For JoinIR lowering phase
- Both maintain consistent field initialization
## Benefits
- **Clear separation**: Documented different contexts for each builder
- **Maintainability**: Future developers understand which builder to use
- **No code changes**: Pure documentation improvement
- **Cross-references**: Easy navigation between related modules
## Testing
✅ All loop_scope_shape tests pass (24 tests)
✅ No behavioral changes
✅ Documentation-only refactoring

refactor(joinir): Phase 183-2 Consolidate CarrierInfo initialization
...
Makes CarrierInfo::from_variable_map() the primary initialization method.
Common pattern initializer now delegates to this centralized logic.
## Changes
1. **Primary Method: CarrierInfo::from_variable_map()**:
- Now the single source of truth for CarrierInfo construction
- Used by both MIR and JoinIR contexts
- Documented as primary initialization method (Phase 183-2)
2. **CommonPatternInitializer Refactoring**:
- Converted to thin wrapper around `CarrierInfo::from_variable_map()`
- Delegates carrier collection to primary method
- Only adds pattern-specific exclusion filtering
- Reduced code duplication (~30 lines removed)
3. **Documentation Updates**:
- `carrier_info.rs`: Added Phase 183-2 section explaining primary role
- `common_init.rs`: Documented delegation strategy
- Clear separation of concerns between modules
4. **Removed Duplicate Logic**:
- Eliminated manual carrier collection in `common_init.rs`
- Removed `CarrierVar` import (no longer directly constructed)
- Unified sorting and validation in one place
## Benefits
- **Single source of truth**: CarrierInfo construction logic in one module
- **Consistency**: Same initialization algorithm across MIR/JoinIR
- **Maintainability**: Changes to carrier logic only needed once
- **Testability**: Primary logic tested in carrier_info module
## Testing
✅ All carrier_info tests pass (7 tests)
✅ All pattern tests pass (124 tests)
✅ No behavioral changes

refactor(joinir): Phase 183-1 Unify pattern detection in loop_pattern_detection
...
Consolidates duplicate pattern detection logic across two routing layers.
## Changes
1. **Unified Detection Documentation**:
- Added Phase 183 comments to `loop_pattern_detection::classify()`
- Documented that this is the single source of truth for pattern classification
- Both routers now reference this centralized function
2. **Router Documentation Updates**:
- `patterns/router.rs`: Added Phase 183 comments explaining structure-based routing
- `loop_pattern_router.rs`: Added unified detection section
- Both routers now explicitly reference shared detection logic
3. **Improved Debug Output**:
- Added `pattern_kind` to debug message in `route_loop_pattern()`
- Helps diagnose pattern matching failures
## Benefits
- **Single source of truth**: Pattern classification logic in one place
- **Consistency**: Both routers use same detection algorithm
- **Maintainability**: Changes to classification rules only needed once
- **Documentation**: Clear references between routers and detection module
## Testing
✅ All loop_pattern_detection tests pass
✅ Pattern 2 tests pass
✅ No behavioral changes, pure documentation/organization refactoring

docs(joinir): Phase 182 final completion report
...
Phase 182 PARTIAL SUCCESS Summary:
✅ Pattern1/Pattern2 routing and execution verified
✅ Representative tests created (2/2 PASS)
✅ Blockers identified with clear remediation paths
Achievements:
- Design document created (phase182-simple-loops-design.md)
- Routing whitelist updated (+3 JsonParser methods)
- Pattern routing verified with structure-only tracing
- 2 representative tests created and passing:
* phase182_p1_match_literal.hako (Pattern1 Simple)
* phase182_p2_break_integer.hako (Pattern2 Break)
- Documentation updated (architecture + CURRENT_TASK)
Blockers Identified:
1. LoopBodyLocal variable handling
- Current: Trim-specific carrier promotion (fails for normal loops)
- Needed: Role-based distinction (condition vs body-only locals)
- Impact: Blocks _parse_number, _atoi, most JsonParser loops
2. String concatenation filter (Phase 178)
- Current: Conservative rejection of string ops
- Needed: Gradual enablement for JsonParser use cases
- Impact: Blocks loops with string building
Next Steps (Phase 183):
- Minimal fix for LoopBodyLocal handling
- String concat enablement with safety checks
- 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

test(joinir): Phase 182-5 Add P1/P2 pattern verification tests
...
Phase 182-5 Test Results:
✅ Pattern1 (Simple) - phase182_p1_match_literal.hako PASSES
✅ Pattern2 (Break) - phase182_p2_break_integer.hako PASSES
Verification:
- P1 routes correctly to Pattern1_Minimal
- P2 routes correctly to Pattern2_WithBreak
- Both execute successfully with integer operations
- _match_literal logic verified (string matching with early return)
Blockers for actual JsonParser loops (_parse_number, _atoi):
1. LoopBodyLocal variables (ch, digit_pos, pos) trigger promotion requirement
- Current system only handles Trim-specific carrier promotion
- P2 should allow purely local temp variables (not promoted to carriers)
2. String operation filter (Phase 178)
- Conservatively rejects string concat: num_str = num_str + ch
- Need gradual enablement for JsonParser use cases
Next steps (Phase 182-6):
- Document blockers and workaround strategies
- Recommend LoopBodyLocal handling improvements for Phase 183+
