feat(joinir/dev): Phase 126 wire available_inputs into normalized builder
...
- AvailableInputsCollectorBox::collect() called in lower_function_body (dev-only)
- try_lower_if_only() signature extended (accepts available_inputs)
- EnvLayout::from_contract() now uses real available_inputs (not empty stub)
- Unit tests updated (empty BTreeMap for backward compat)
- All 23 normalized_shadow tests PASS

refactor(control_tree): Phase 125 P2-P4 introduce EnvLayout (writes+inputs) + Return(Variable) from inputs
...
Phase 125 P2: EnvLayout introduction
- Add EnvLayout struct (writes + inputs)
- from_contract() creates layout from StepTreeContract + available_inputs
- SSOT: inputs = reads ∩ available_inputs (deterministic order)
- No AST inference (don't capture from AST, use provided available_inputs)
Phase 125 P2: Builder env mapping
- lower_if_only_to_normalized: Use EnvLayout to create env map
- writes: Generate ValueId (as before)
- inputs: Reference ValueId from available_inputs (placeholder for P3)
- Function params: writes only (inputs come from outer scope)
Phase 125 P4: Return(Variable) resolution extended
- lower_return_value: Check env (writes + inputs)
- If found: return it (Phase 124 for writes, Phase 125 for inputs)
- If not found: Fail-Fast with structured error + hint
- Hint: "Pass as param, add to pinned capture, or define before if"
- Phase 125 errors return Ok(None) (out of scope, graceful degradation)
Unit tests:
- test_return_variable_from_env: PASS (Phase 124 regression)
- test_return_variable_out_of_scope: PASS (updated for Phase 125)
- test_return_variable_from_inputs_stub: PASS (P3 not wired yet)
- All 1160 lib tests PASS (no regression)
Note:
- P3 (available_inputs wiring) not implemented yet
- available_inputs is empty BTreeMap (stub)
- EnvLayout.inputs will be empty until P3 is wired
- Structured error tags: [phase125/return/var_not_in_env]

feat(control_tree): Phase 124 return variable from env (dev-only)
...
Phase 124-P3:
- Add env: BTreeMap<String, ValueId> from writes in lower_if_only_to_normalized
- Pass env and contract to lower_return_from_tree, lower_if_node, lower_return_value
- Implement Return(Variable) support:
- If variable in env (writes): Ret(Some(vid))
- If variable not in env: Err (out of scope, phase124 error)
- Add phase124 errors to Ok(None) conversion (dev-only compatibility)
- Add unit test: test_return_variable_from_env (verifies Ret(Some(ValueId(1))))
- All 1159 tests PASS

refactor(control_tree): include reads in StepTreeContract signature
...
Phase 124-P2:
- Add reads: BTreeSet<String> to StepTreeContract
- Include reads in signature_basis_string (format: ...;reads=...;...)
- Update from_facts() to copy reads from StepTreeFacts
- Update all StepTreeContract construction sites (builder.rs, parity.rs tests)
- Update test expected signature to include reads field
- Maintains determinism: BTreeSet guarantees stable iteration order

feat(control_tree): Phase 123 if-only compare+return lowering (Normalized, dev-only)
...
Implements Phase 123 P3: If(cond_ast) minimal lowering with graceful degradation.
**What's Implemented**:
- If node lowering with minimal binary comparison (Variable op Integer)
- Supported operators: ==, !=, <, <=, >, >=
- Generates: Compare + Const + Ret structure
- Graceful degradation: returns Ok(None) for unsupported patterns
**Key Design Decisions**:
1. **Graceful Degradation**: Phase 123 limitations return `Ok(None)` instead of failing
- Allows dev-only mode to coexist with legacy code
- Error messages prefixed with `[phase123/...]` are caught
2. **Fail-Fast with Structured Errors**: All limitations use structured error codes
- Format: `[phase123/category/specific]`
3. **Box-First Principles**:
- `parse_minimal_compare`: Single responsibility parser
- `verify_branch_is_return_literal`: Branch validation box
- `lower_if_node`: If lowering box
**Implementation**:
- Added `lower_if_node`: If lowering with minimal compare
- Added `parse_minimal_compare`: Binary comparison parser
- Added `verify_branch_is_return_literal`: Branch validator
- Updated `lower_if_only_to_normalized` return type: `Result<Option<...>, ...>`
- Updated `test_return_variable_out_of_scope`: Verifies graceful degradation
- Added `test_if_minimal_compare`: Verifies If lowering structure
**Tests**: 8 passed (including graceful degradation test)

feat(control_tree): emit Normalized JoinModule for if-only (dev-only)
...
Phase 122 P1: StepTree→Normalized JoinModule generation
- Generate env layout from writes (SSOT, deterministic)
- Minimal implementation: main function + Ret only
- Full If/Assign/Return lowering in future P2-P4
- Dev-only: no behavior change to existing path
