lance-graph — Progress Tracker

Tracks progress against the master integration plan plateaus. See /home/user/INTEGRATION_PLAN.md for full context.

Plateau 0: Everything Compiles

• bgz17 crate compiles and tests pass (121 tests)
• lance-graph core compiles (SPO: 30 tests, Cypher: 44 tests, Semirings: 10 tests)
• One DataFusion integration test fails to compile — needs investigation

Plateau 1: Schema Migration

• 1C.4: Update FINAL_STACK.md with crewai-rust + AriGraph awareness — DONE (2026-03-22)
• 1C.5: Update integration_phases.md — Phase 2 marked DONE (2026-03-22)

Plateau 2: ladybug-rs Migration

• N/A for lance-graph (lance-graph is consumed, not changed)
• 2B.3: ladybug-rs wires lance-graph semirings into src/graph/spo/
• 2B.4: ladybug-rs delegates Cypher execution to lance-graph
• 2B.5: ladybug-rs uses lance-graph SPO store as backend

• 3A.5: Wire TruthGate into search results
• 3D.1: GraphRouter 3-backend routing
• 3D.2: Palette 2-hop ranking validation (ρ > 0.9)
• 3D.3: Performance benchmark
