From 5e662eaaf6b27344e31a79a72cd9ab7c0f11cbc2 Mon Sep 17 00:00:00 2001 From: tomoaki Date: Fri, 19 Dec 2025 08:23:20 +0900 Subject: [PATCH] fix(normalization): Phase 143 execution fix - Param region SSOT MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Problem: normalized_helpers allocated env params as ValueId(1,2...) in PHI Reserved region (0-99) instead of Param region (100-999) per JoinValueSpace contract. Root cause: All 4 normalized shadow modules started from next_value_id=1, violating the Param region contract. Solution: - Add NormalizedHelperBox::alloc_env_params_param_region() that allocates params starting from PARAM_MIN (100) - Update 4 normalized shadow files to use new API: - loop_true_if_break_continue.rs - loop_true_break_once.rs - if_as_last_join_k.rs - post_if_post_k.rs - Fix instruction_rewriter.rs type mismatch (func.signature.params → func.params) Verification: - Unit tests: 69/69 PASS - VM smoke: exit code 7 ✅ - LLVM EXE smoke: exit code 7 ✅ (timeout resolved!)
