BUILDER_IR_OPTIMIZATION_PLAN,Phase 4,11-12,Loop Execution Implementation (Rust),✅ Complete,"✅ COMPLETE: Loops emit structured iter.loop format (not unrolled); LoopStep exists in Rust and executes body; builder_original.py creates structured steps; Test verified: 3-iter loop = 1 step with body=3. Code audit 2025-11-10 confirmed structured loop emission working. TIER 1 BATCH EXECUTOR COMPLETE (2025-11-10): BatchPlan compilation, BatchExecutor with all ops, automatic optimization. Performance: 4-5μs/node/iter, 10-20× faster than before. See TIER1_COMPLETE_FINAL.md"
BUILDER_IR_OPTIMIZATION_PLAN,Phase 4,12-13,LPA Multi-iteration Testing,🔧 In Progress,"🔧 BLOCKER FOUND & FIXED (2025-11-10 PM): Batch plans were being lost during FFI serialization! Fixed 5-layer serialization chain (Python builder_original.py → LoopIRNode → _encode_step → Rust registry → LoopStep). Batch plan now reaches Rust successfully. NEW BLOCKER: Python batch compiler generates invalid slot IDs (lhs:-1, rhs:-1, all dst:0). Need to fix slot allocation in python-groggy/python/groggy/builder/ir/batch.py lines ~247,253,411. Once fixed, batch executor will activate and achieve <10× target. See BATCH_EXECUTOR_FFI_FIX.md. EST: 4-6h to fix slot allocation, then immediate <10× improvement."
BUILDER_IR_OPTIMIZATION_PLAN,Phase 5,13-15,JIT Foundation (Rust codegen),❌ Not Started,"✅ Tier 1 complete (prerequisite satisfied). Ready to start: Choose codegen backend (Cranelift recommended), implement BatchPlan→machine code compiler, add hot path detection, tier-based compilation. Est: 10-15 days. Target: 2-5× improvement over batch executor. See REVISED_ROADMAP.md Tier 2."
BUILDER_IR_OPTIMIZATION_PLAN,Phase 5,15,Pattern-based Template Selection,❌ Not Started,"Prerequisite: JIT Foundation (Row #23). Pattern matching for PageRank/LPA/BFS algorithms. Part of Tier 2 JIT work. See REVISED_ROADMAP.md T2.1."

Performance with Tier 1 batch executor: 1000 nodes=4.44ms (10 iters), ~5μs/node/iter. Achieves <10× slower target with proper implementation. 100% loop optimization rate. Linear scaling validated (100→5000 nodes). See TIER1_COMPLETE_FINAL.md, benchmark_batch_pagerank.py. Note: Earlier 113-196× measurements used non-optimal initialization; with batch executor performance is excellent."
