Task 175-1: Analyzed _parse_string carrier candidates - Identified 3 carriers: pos (position), result (buffer), is_ch_match (promoted) - Categorized as: required carriers (pos, result), promoted carrier (is_ch_match) Task 175-2: Validated existing boxes support multi-carrier - CarrierInfo: Vec<CarrierData> supports arbitrary carriers ✅ - LoopUpdateAnalyzer: Loops over all carriers ✅ - ExitMeta: Vec<(String, ValueId)> supports all exit bindings ✅ - ExitLineReconnector: Reconnects all carriers to variable_map ✅ - No code changes needed - architecture already supports it! Task 175-3: PoC test revealed Pattern2 limitation - Test: test_jsonparser_parse_string_min2.hako (pos + result carriers) - CarrierInfo detected 3 carriers correctly (pos, result, is_ch_match) - variable_map contains all carriers at pattern2_start - BUT: Pattern2's Trim optimization only emits pos carrier in MIR - MIR shows result stays as empty string (no loop update emitted) - Root cause: Trim pattern focuses on position-only optimization Task 175-4: Documentation updates - Created: phase175-multicarrier-design.md (comprehensive analysis) - Updated: CURRENT_TASK.md (Phase 175 completion) - Updated: routing.rs (added JsonParserStringTest2 whitelist) Key Finding: - Architecture is sound ✅ - all boxes support multi-carrier - Pattern2 implementation gap ❌ - Trim optimization ignores non-position carriers - Phase 176 scope: Extend Pattern2 to emit all carrier updates Next: Phase 176 for escape sequence handling and full multi-carrier emission
