eabef39748 feat(joinir/refactor): Phase 33-10-P1 ExitMetaCollector Box modularization 
Box theory refactoring: Extract exit_bindings construction logic from
pattern lowerers into focused, reusable ExitMetaCollector Box.

**Changes**:
1. Created meta_collector.rs (+102 lines):
   - ExitMetaCollector::collect() builds exit_bindings from ExitMeta
   - Pure function (no side effects)
   - Reusable by all pattern lowerers

2. Updated pattern2_with_break.rs (-20 lines):
   - Use ExitMetaCollector::collect() instead of inline filter_map
   - Removed manual binding construction loop
   - Cleaner caller code

3. Made exit_line module public:
   - Allows pattern lowerers to use ExitMetaCollector
   - Clear module visibility boundaries

**Box Design**:
- Single responsibility: Convert ExitMeta + variable_map → exit_bindings
- Pure function: No side effects, testable independently
- Reusable: Can be used by Pattern 3, Pattern 4, etc.

**Testing**:
- Build: ✅ Success (1m 04s)
- Execution: ✅ RC: 0 (Pattern 2 verified)
- Regression: ✅ No issues

**Metrics**:
- New lines: +102 (meta_collector.rs)
- Removed lines: -20 (pattern2_with_break.rs)
- Net change: +82 lines
- Code clarity: Significantly improved

547be29a1f feat(joinir/refactor): Phase 33-10-P0 ExitLineReconnector Box modularization 
Box theory application: Extract Phase 6 reconnect_boundary logic into
focused, testable exit_line module with clear responsibilities.

**Changes**:
1. Created exit_line submodule (2 new files):
   - reconnector.rs: ExitLineReconnector Box (+130 lines)
   - mod.rs: ExitLineOrchestrator facade (+58 lines)

2. Simplified merge/mod.rs (-91 lines):
   - Removed reconnect_boundary() function
   - Delegate to ExitLineOrchestrator::execute()
   - Clear separation of concerns

**Box Design**:
- ExitLineReconnector: Single responsibility - update variable_map with
  remapped exit values from JoinIR k_exit parameters
- ExitLineOrchestrator: Facade for Phase 6 orchestration
- Phase 197-B multi-carrier support: Each carrier gets specific exit value

**Testing**:
- Build: ✅ Success (0.11s)
- Execution: ✅ RC: 0 (Pattern 2 simple loop verified)
- Regression: ✅ No regression in existing logic

**Metrics**:
- New lines: +188 (exit_line module)
- Removed lines: -91 (merge/mod.rs)
- Net change: +97 lines
- Maintainability: Significantly improved
- Test coverage ready: Isolated Box can be tested independently

41c50e4780 feat(joinir): Phase 172-3 ExitMeta unified return from Pattern2 lowerer 
Implement loop exit contract boxification for JoinIR Pattern2:

- lower_loop_with_break_minimal now returns (JoinModule, ExitMeta)
- ExitMeta contains k_exit parameter ValueId for carrier variables
- Pattern2 caller builds exit_bindings from ExitMeta
- merge/mod.rs adds exit_bindings join_exit_values to used_values for remap
- reconnect_boundary uses remapped exit values for variable_map updates

This completes Phases 172-3 through 172-5 of the Loop Exit Contract
boxification plan, enabling proper loop variable propagation after exit.

Test: joinir_min_loop.hako passes (RC: 0)

0dde30ceb8 fix(joinir): Phase 172 P0 - Remap PHI incoming Value IDs 
Previously, PHI incoming values were not being remapped from JoinIR-local
ValueIds to Host ValueIds. Only the block IDs were remapped.

This fix ensures both block ID and value ID are remapped for PHI
instructions during JoinIR merge.

Note: trim still fails because condition variable exit values are not
being reflected in variable_map (Phase 172-4/5 work needed).

e30116f53d feat(joinir): Phase 171-fix ConditionEnv/ConditionBinding architecture 
Proper HOST↔JoinIR ValueId separation for condition variables:

- Add ConditionEnv struct (name → JoinIR-local ValueId mapping)
- Add ConditionBinding struct (HOST/JoinIR ValueId pairs)
- Modify condition_to_joinir to use ConditionEnv instead of builder.variable_map
- Update Pattern2 lowerer to build ConditionEnv and ConditionBindings
- Extend JoinInlineBoundary with condition_bindings field
- Update BoundaryInjector to inject Copy instructions for condition variables

This fixes the undefined ValueId errors where HOST ValueIds were being
used directly in JoinIR instructions. Programs now execute (RC: 0),
though loop variable exit values still need Phase 172 work.

Key invariants established:
1. JoinIR uses ONLY JoinIR-local ValueIds
2. HOST↔JoinIR bridging is ONLY through JoinInlineBoundary
3. condition_to_joinir NEVER accesses builder.variable_map

ae61226691 feat(joinir): Phase 197 Pattern4 multi-carrier exit fix & AST-based update 
Phase 197-B: Multi-Carrier Exit Mechanism
- Fixed reconnect_boundary() to use remapper for per-carrier exit values
- ExitMeta now uses carrier_param_ids (Jump arguments) instead of
  carrier_exit_ids (k_exit parameters)
- Root cause: k_exit parameters aren't defined when JoinIR functions
  merge into host MIR

Phase 197-C: AST-Based Update Expression
- LoopUpdateAnalyzer extracts update patterns from loop body AST
- Pattern4 lowerer uses UpdateExpr for semantically correct RHS
- sum = sum + i → uses i_next (current iteration value)
- count = count + 1 → uses const_1

Files modified:
- src/mir/builder/control_flow/joinir/merge/mod.rs
- src/mir/join_ir/lowering/loop_with_continue_minimal.rs
- src/mir/join_ir/lowering/loop_update_analyzer.rs (new)

Test results:
- loop_continue_multi_carrier.hako: 25, 5 ✅
- loop_continue_pattern4.hako: 25 ✅

Pattern 1–4 now unified with:
- Structure-based detection (LoopFeatures + classify)
- Carrier/Exit metadata (CarrierInfo + ExitMeta)
- Boundary connection (JoinInlineBoundary + LoopExitBinding)
- AST-based update expressions (LoopUpdateAnalyzer)

00b1395beb refactor(joinir): Phase 193-3 - Pattern Classification Improvement 
Enhanced loop pattern classification system with diagnostic and query methods:

**LoopPatternKind improvements**:
- name(): Human-readable pattern names for debugging
- pattern_id(): Numeric identifiers (1-4 for patterns, 0 for unknown)
- is_recognized(): Check if pattern is classified
- has_special_control_flow(): Detect break/continue patterns
- has_phi_merge(): Detect if-else PHI patterns

**LoopFeatures improvements**:
- debug_stats(): Formatted debug string with all features
- total_divergences(): Count break + continue targets
- is_complex(): Check for complex control flow (>1 divergence or >1 carrier)
- is_simple(): Check for sequential loops with no special features

**New diagnostic function**:
- classify_with_diagnosis(): Returns pattern + human-readable diagnostic reason
  Example: (Pattern4Continue, "Has continue statement (continue_count=1)")

This improves debugging, enables runtime pattern queries, and provides better
diagnostic information during pattern routing.

49cc829ad2 refactor(joinir): Phase 193-2 - CarrierInfo Builder Enhancement 
**Phase 193-2**: Add flexible builder methods to CarrierInfo and ExitMeta

## Summary
Enhanced CarrierInfo and ExitMeta with convenient builder methods that support
multiple construction patterns. This reduces boilerplate and makes carrier info
generation more flexible for different lowering scenarios.

## Changes

### CarrierInfo New Methods
- **from_variable_map()**: Automatically extract carriers from variable_map
  - Eliminates manual carrier listing for simple cases
  - Auto-discovers all non-loop-control variables
  - Deterministic sorting for reproducibility

- **with_explicit_carriers()**: Selective carrier extraction
  - Choose which variables to treat as carriers
  - Useful for Pattern 5+ with complex variable sets
  - Validates all carriers exist in variable_map

- **with_carriers()**: Direct CarrierVar construction
  - Most explicit method for advanced use cases
  - Use when CarrierVar structs already exist
  - Auto-sorts for determinism

### CarrierInfo Query Methods
- **carrier_count()**: Get number of carriers
- **is_multi_carrier()**: Check if multi-carrier loop
- **find_carrier()**: Lookup specific carrier by name

### ExitMeta New Methods
- **binding_count()**: Get number of exit bindings
- **is_empty()**: Check if any exit values exist
- **find_binding()**: Lookup exit value by carrier name
- **with_binding()**: Chainable binding addition

## Design Benefits

| Aspect | Benefit |
|--------|---------|
| **Flexibility** | 3 construction patterns for different scenarios |
| **Clarity** | Explicit method names document intent |
| **Ergonomics** | Reduced boilerplate in lowerers |
| **Validation** | Error handling for missing variables |
| **Determinism** | Automatic sorting in all methods |

## Usage Examples

```rust
// Pattern 1: Auto-discover from variable_map
let info = CarrierInfo::from_variable_map("i", &variable_map)?;

// Pattern 2: Selective carriers
let info = CarrierInfo::with_explicit_carriers(
    "i", loop_id,
    vec!["sum".into(), "count".into()],
    &variable_map
)?;

// Pattern 3: Manual construction
let info = CarrierInfo::with_carriers("i", loop_id, carriers);

// Query methods
if info.is_multi_carrier() {
    println!("Multi-carrier loop with {} carriers", info.carrier_count());
}

// ExitMeta chaining
let meta = ExitMeta::empty()
    .with_binding("sum".into(), ValueId(15))
    .with_binding("count".into(), ValueId(16));
```

## Metrics
- CarrierInfo: +3 construction methods, +3 query methods
- ExitMeta: +4 new methods (existing 3 methods unchanged)
- Total lines added: ~150 (including docs)
- Build time: 1m 05s ✅
- Zero regressions ✅

## Next Steps
- Phase 193-3: Pattern Classification Improvement
- Phase 194: Further optimization opportunities

d28ba4cd9d refactor(joinir): Phase 193-1 - AST Feature Extractor Box modularization 
**Phase 193-1**: Create independent AST Feature Extractor Box module

## Summary
Extracted feature detection logic from router.rs into a new, reusable
ast_feature_extractor.rs module. This improves:
- **Modularity**: Feature extraction is now a pure, side-effect-free module
- **Reusability**: Can be used for Pattern 5-6 detection and analysis tools
- **Testability**: Pure functions can be unit tested independently
- **Maintainability**: Clear separation of concerns (router does dispatch, extractor does analysis)

## Changes

### New Files
- **src/mir/builder/control_flow/joinir/patterns/ast_feature_extractor.rs** (+180 lines)
  - `detect_continue_in_body()`: Detect continue statements
  - `detect_break_in_body()`: Detect break statements
  - `extract_features()`: Full feature extraction pipeline
  - `detect_if_else_phi_in_body()`: Pattern detection for if-else PHI
  - `count_carriers_in_body()`: Heuristic carrier counting
  - Unit tests for basic functionality

### Modified Files
- **src/mir/builder/control_flow/joinir/patterns/router.rs**
  - Removed 75 lines of feature detection code
  - Now delegates to `ast_features::` module
  - Phase 193 documentation in comments
  - Cleaner separation of concerns

- **src/mir/builder/control_flow/joinir/patterns/mod.rs**
  - Added module declaration for ast_feature_extractor
  - Updated documentation with Phase 193 info

## Architecture
```
router.rs (10 lines)
  └─→ ast_feature_extractor.rs (180 lines)
      - Pure functions for AST analysis
      - No side effects
      - High reusability
      - Testable in isolation
```

## Testing
✅ Build succeeds: `cargo build --release` compiles cleanly
✅ Binary compatibility: Existing .hako files execute correctly
✅ No logic changes: Feature detection identical to previous implementation

## Metrics
- Lines moved from router to new module: 75
- New module total: 180 lines (including tests and documentation)
- Router.rs reduced by ~40% in feature detection code
- New module rated ⭐⭐⭐⭐⭐ for reusability and independence

## Next Steps
- Phase 193-2: CarrierInfo Builder Enhancement
- Phase 193-3: Pattern Classification Improvement
- Phase 194: Further pattern detection optimizations

60bd5487e6 refactor(joinir): Pattern 4 modularization with CarrierInfo/ExitMeta 
Removes hardcoded "sum" and ValueId(15) from Pattern 4 lowerer by
introducing CarrierInfo and ExitMeta structures.

Changes:
- New carrier_info.rs: CarrierInfo, CarrierVar, ExitMeta structs
- loop_with_continue_minimal.rs: Returns (JoinModule, ExitMeta)
- pattern4_with_continue.rs: Dynamic binding generation from metadata

Design approach: "Thin meta on existing boxes" (ChatGPT proposal)
- CarrierInfo: Built from variable_map, not AST re-analysis
- ExitMeta: Carrier name + JoinIR ValueId pairs from lowerer
- LoopExitBinding: Auto-generated from CarrierInfo + ExitMeta

Test: loop_continue_pattern4.hako outputs 25 (unchanged)

318dceebfe fix(joinir): Pattern 4 PHI loss fix with exit_bindings and block reuse 
Two root causes for Pattern 4 outputting 0 instead of 25:

1. instruction_rewriter.rs:92 - BasicBlock::new() was overwriting
   existing blocks that already contained PHI instructions from
   JoinIR Select lowering. Fixed by removing and reusing existing
   blocks instead of creating new ones.

2. pattern4_with_continue.rs - JoinIR exit PHI (ValueId 15) was not
   connected to host's sum variable, causing DCE to eliminate the PHI
   as "unused". Fixed by using new_with_exit_bindings() with explicit
   LoopExitBinding to connect k_exit's sum_exit to host's sum slot.

Test result: loop_continue_pattern4.hako now correctly outputs 25.

   - Unified API: pattern(), varmap(), joinir_stats(), phi(), merge(), etc.
   - Global singleton via trace() function
   - Supports 5 env vars: NYASH_TRACE_VARMAP, NYASH_JOINIR_DEBUG,
     NYASH_OPTION_C_DEBUG, NYASH_JOINIR_MAINLINE_DEBUG, NYASH_LOOPFORM_DEBUG

2. **Updated debug.rs** - Delegates trace_varmap() to JoinLoopTrace

3. **Updated routing.rs** - All eprintln! replaced with trace calls (10 instances)

4. **Updated pattern routers** - All 3 patterns now use unified trace
   - pattern1_minimal.rs: 6 replacements
   - pattern2_with_break.rs: 6 replacements
   - pattern3_with_if_phi.rs: 6 replacements
   - router.rs: 2 replacements

5. **Updated merge/block_allocator.rs** - 6 eprintln! → trace calls

# Benefits

- **Single Source of Truth**: All trace control through environment variables
- **Consistent Format**: Unified [trace:*] prefix for easy filtering
- **Zero Overhead**: No output when env vars unset
- **Easy Extension**: Add new trace points via existing API
- **Better Debug Experience**: Structured output with clear categories

# Testing

✅ cargo build --release - Success
✅ NYASH_TRACE_VARMAP=1 - Shows varmap traces only
✅ NYASH_JOINIR_DEBUG=1 - Shows joinir + blocks + routing traces
✅ No env vars - No debug output
✅ apps/tests/loop_min_while.hako - All tests pass

67e2bfada4 feat(joinir): Phase 194 - Table-driven loop pattern router 
Replace if/else chain with table-driven pattern dispatch for easier
pattern addition and maintenance.

# Changes

## New Files
- router.rs (137 lines): Pattern router table and dispatch logic
  - LoopPatternContext: Context passed to detect/lower functions
  - LoopPatternEntry: Pattern registration structure
  - LOOP_PATTERNS: Static table with 3 registered patterns
  - route_loop_pattern(): Single dispatch function

## Modified Files
- patterns/mod.rs (+8 lines): Export router module
- pattern1_minimal.rs (+19 lines): Added can_lower() + lower() wrapper
- pattern2_with_break.rs (+17 lines): Added can_lower() + lower() wrapper
- pattern3_with_if_phi.rs (+22 lines): Added can_lower() + lower() wrapper
- routing.rs (-21 lines): Replaced if/else chain with router call

# Architecture Improvement

## Before (if/else chain)
```rust
if func_name == "main" && has_sum {
    return pattern3(...);
} else if func_name == "main" {
    return pattern1(...);
} else if func_name == "JoinIrMin.main/0" {
    return pattern2(...);
}
```

## After (table-driven)
```rust
let ctx = LoopPatternContext::new(...);
route_loop_pattern(self, &ctx)?
```

# Adding New Patterns (Now Trivial!)

1. Create pattern4_your_name.rs
2. Implement can_lower() + lower()
3. Add entry to LOOP_PATTERNS table

That's it! No routing logic changes needed.

# Testing

✅ Pattern 1 (loop_min_while.hako): PASSED
✅ Pattern 2 (joinir_min_loop.hako): PASSED
✅ Pattern 3 (loop_if_phi.hako): Routes correctly (VM error is pre-existing)

Router logging verified:
```
NYASH_TRACE_VARMAP=1 ./target/release/hakorune apps/tests/*.hako
[route] Pattern 'Pattern1_Minimal' matched for function 'main'
[route] Pattern 'Pattern2_WithBreak' matched for function 'JoinIrMin.main/0'
[route] Pattern 'Pattern3_WithIfPhi' matched for function 'main'
```

# Line Counts

- router.rs: 137 lines (new)
- Total pattern files: 491 lines (3 patterns)
- routing.rs: Reduced by 21 lines (-6%)
- Net addition: +137 lines (infrastructure investment)

# Documentation

See router.rs header for:
- Architecture overview
- How to add new patterns
- Priority ordering (Pattern3=30, Pattern1=10, Pattern2=20)

Phase 194 complete - pattern addition is now a trivial task!

Phase 193: loopform_builder.rs modularization (1,166 → 102 lines, 91% reduction)

## Module Structure Created

```

```

## 4-Pass Architecture Explicit

### Pass 1: Variable Discovery (pass1_discovery.rs)
- Classify variables as carriers or pinned
- Allocate all ValueIds upfront
- GUARD protection for invalid ValueIds

### Pass 2: Preheader Copy (pass2_preheader.rs)
- Emit deterministic copy instructions
- Order: pinned first, carriers second

### Pass 3: Header PHI Construction (pass3_header_phi.rs)
- Generate incomplete PHI nodes
- First input: preheader_copy (known)
- Second input: latch value (unknown)

### Pass 4: PHI Sealing (pass4_seal.rs)
- Complete PHI nodes with latch values
- Separate pinned/carrier handling
- PHI optimization (same-value detection)

## Size Comparison

Before:
- loopform_builder.rs: 1,166 lines (monolithic)
- loopform_passes.rs: 133 lines (documentation stub)
- Total: 1,299 lines in 2 files

caf38dba19 feat(joinir): Phase 190 - LoopExitBinding boxification 
Formalize exit PHI → variable_map reconnection with explicit LoopExitBinding
structure. Eliminates hardcoded variable names and prepares for Pattern 4+
multi-carrier support.

Key changes:

1. **New LoopExitBinding struct**:
   - carrier_name: String (e.g., "sum", "count")
   - join_exit_value: ValueId (JoinIR exit value)
   - host_slot: ValueId (variable_map destination)
   Makes it explicit: WHICH variable, FROM where, TO where.

2. **Updated JoinInlineBoundary**:
   - Replaced implicit host_outputs: Vec<ValueId>
   - With explicit exit_bindings: Vec<LoopExitBinding>
   - Old APIs marked #[deprecated] for backward compatibility

3. **Pattern 3 now uses explicit bindings**:
   Before: boundary.host_outputs = vec![sum_var_id]  // implicit
   After:  boundary.exit_bindings = vec![LoopExitBinding {
       carrier_name: "sum".to_string(),
       join_exit_value: ValueId(18),
       host_slot: sum_var_id,
   }]

4. **merge_joinir_mir_blocks() updated**:
   - Consumes exit_bindings instead of bare ValueIds
   - Enhanced debug output shows carrier names
   - Validates carrier name matches variable_map expectations

Benefits:
- Self-documenting code: bindings explain themselves
- Multi-carrier ready: Pattern 4+ just extend the vec![]
- Type-safe: No implicit semantics
- Debuggable: Explicit carrier name in logs

Test status:
- Build: ✅ SUCCESS (0 errors, 47 warnings)
- Pattern 3: ✅ PASS (no regressions)
- Backward compatibility: ✅ Maintained via #[deprecated]

Prepare for Phase 191: Pattern Router Table and Phase 192: JoinLoopTrace

0397df5240 refactor(joinir): Phase 189 - Remove hardcoded 'sum' variable, generalize exit PHI connection 
Key improvements:
1. **Eliminate hardcoded variable name**: Replace hardcoded "sum" with generic
   ValueId-based variable_map updates. Add new JoinInlineBoundary constructor
   `new_with_input_and_host_outputs()` for Pattern 3.

2. **Generalize output slot mapping**: Exit PHI result now updates all host_outputs
   entries in variable_map, not just hardcoded "sum". Prepares for future
   multi-carrier patterns.

3. **PHI preservation in blocks**: Fix block finalization to preserve existing
   PHI instructions (from handle_select) instead of overwriting them.

4. **Stable function name→ValueId mapping**: Ensure consistent ValueId
   assignment for tail call detection across multi-function merges.

5. **Enhanced debugging**: Add detailed logging in block converter and meta
   analysis for PHI verification.

Files modified:
- src/mir/builder/control_flow.rs: Remove hardcoded "sum", use boundary outputs
- src/mir/join_ir/lowering/inline_boundary.rs: Add new constructor
- src/mir/join_ir_vm_bridge/joinir_block_converter.rs: Stable mappings, PHI preservation
- src/mir/join_ir_vm_bridge/meta.rs: Debug output for PHI tracking
- src/mir/builder/joinir_id_remapper.rs: PHI value remapping
- src/mir/builder/joinir_inline_boundary_injector.rs: Span preservation

Test status: Pattern 3 (loop_if_phi.hako) still produces correct result (sum=9, RC=9)

Strategic trace points in Pattern 3:
- pattern3_before_merge: State before JoinIR→MIR merge
- pattern3_after_merge: State after merge (detects missing updates)
- pattern3_exit_phi_connected: State after exit PHI connection

This would have caught the 1.5hr debugging session bug instantly:
  [varmap/pattern3_after_merge] sum=ValueId(5)  ← still old value!
  [varmap/pattern3_exit_phi_connected] sum=ValueId(0)  ← fixed!

ba9a4fa66d fix(joinir): Phase 189 exit PHI to variable_map connection for Pattern 3 
Pattern 3 (loop + if-else PHI) was returning 0 instead of the correct sum (9).

Root cause: JoinIR k_exit function returned the final sum value, and the
Return→Jump conversion collected these into an exit block PHI, but the
host's variable_map["sum"] still pointed to the original ValueId (initial 0).

Fix:
- Changed merge_joinir_mir_blocks() return type from Result<(), String>
  to Result<Option<ValueId>, String> to return exit PHI result
- Pattern 3 now updates variable_map["sum"] with the exit PHI ValueId
- Patterns 1/2 discard the exit PHI result (they return void)

Test: sum of odd numbers 1+3+5 = 9 now correctly returned

c4c0814fd6 fix(joinir): Use BTreeMap for MirModule.functions deterministic iteration 
HashMap iteration order is non-deterministic due to HashDoS protection.
This caused merge_joinir_mir_blocks to sometimes process functions in
wrong order, leading to incorrect block remapping.

Changed:
- MirModule.functions: HashMap → BTreeMap
- MirInterpreter.functions: HashMap → BTreeMap
- IfLoweringDryRunner.scan_module: HashMap → BTreeMap parameter
