feat(joinir): Phase 53 - SELFHOST-NORM-DEV-EXPAND implementation
Expanded selfhost dev Normalized target with 2 practical P2/P3 loop variations, strengthened structural signature axis, and implemented two-stage detection. Key Changes: 1. Documentation (phase49-selfhost-joinir-depth2-design.md +128 lines): - Added Phase 53 section with candidate selection rationale - Documented two-stage detector strategy (structural primary + dev-only name guard) - Defined structural axis strengthening (carrier count/type, branch patterns) 2. Fixtures (+210 lines): - selfhost_args_parse_p2.program.json (60 lines): P2 with String carrier + conditional branching - selfhost_stmt_count_p3.program.json (150 lines): P3 with 5 carriers + multi-branch if-else 3. Structured Builders (fixtures.rs +48 lines): - build_selfhost_args_parse_p2_structured_for_normalized_dev() - build_selfhost_stmt_count_p3_structured_for_normalized_dev() 4. ShapeGuard Two-Stage Detection (shape_guard.rs +80 lines): - Added SelfhostArgsParseP2/SelfhostStmtCountP3 to NormalizedDevShape enum - Implemented is_selfhost_args_parse_p2(): P2 core family + name guard - Implemented is_selfhost_stmt_count_p3(): 2-10 carrier check + name guard - Updated capability_for_shape() mappings 5. Bridge Integration (bridge.rs +8 lines, normalized.rs +10 lines): - Added shape handlers delegating to existing normalizers - Added roundtrip reconstruction handlers 6. Entry Point Registration (ast_lowerer/mod.rs +2 lines): - Registered selfhost_args_parse_p2/selfhost_stmt_count_p3 as LoopFrontend routes 7. Dev VM Comparison Tests (normalized_joinir_min.rs +40 lines): - normalized_selfhost_args_parse_p2_vm_bridge_direct_matches_structured() - normalized_selfhost_stmt_count_p3_vm_bridge_direct_matches_structured() 8. Test Context Fix (dev_env.rs): - Added thread-local test context depth counter - Fixed deadlock in nested test_ctx() calls via reentrant with_dev_env_if_unset() Structural Axis Growth: P2 family: - Carrier count: 1-3 (unchanged) - NEW: Type diversity (Integer/String mixed) - NEW: Conditional branching patterns (Eq-heavy comparisons) P3 family: - NEW: Carrier count upper bound: 2-10 (was 2-4) - NEW: Multi-branch if-else (5+ branches with nested structure) - NEW: Complex conditional patterns Test Results: - normalized_dev: 40/40 PASS (including 2 new tests) - lib regression: 939 PASS, 56 ignored - Existing behavior unchanged (normalized_dev feature-gated) Phase 53 Achievements: ✅ P2/P3 each gained 1 practical variation (2 total) ✅ Two-stage detection: structural primary + dev-only name guard ✅ Structural axis expanded: 4 axes (carrier count/type/Compare/branch patterns) ✅ All tests PASS, no regressions ✅ Test context deadlock fixed (0.04s for 29 tests) Files Modified: 14 files Lines Added: ~516 lines (net) Implementation: Pure additive (feature-gated) Next Phase (54+): - Accumulate 6+ loops per P2/P3 family - Achieve 5+ stable structural axes - Target < 5% false positive rate - Then shrink/remove name guard scope
