+## Integration Plan Reference (2026-03-22)
+
+The brain surgery tasks are now sequenced within the master integration plan.
+They fall under **Plateau 2, Phase 2C** — only executed AFTER rustynum→ndarray
+migration (2A) and lance-graph wiring (2B) are stable.
+
+**Pre-conditions for surgery:**
+- ndarray builds and tests pass (Plateau 0)
+- ladybug-rs compiles with ndarray (Phase 2A)
+- P1/P3 dead code deleted (Phase 2B.1-2B.2)
+- lance-graph Cypher works end-to-end through server.rs (Phase 2B.4)
+
+**Surgery task dependencies on integration phases:**
+- S1/S2 (delete P1/P3): Unblocked → moved to Phase 2B.1/2B.2
+- L1-L5 (crystal API, codebook, truth): Blocked on Phase 2A.4 (ndarray types)
+- B1-B5 (wire SPO to server): Blocked on Phase 2B.5 (lance-graph SPO backend)
+- N1-N5 (cargo deps, dedup): Blocked on Phase 2B.4 (lance-graph Cypher)
+- K1-K5 (UDF, query seal): Blocked on Phase 2B.6 (server.rs rewire)

+## 8. Migration: rustynum → ndarray (Plateau 2)
+
+ladybug-rs currently depends on 6 rustynum crates for SIMD compute. These are being
+superseded by `AdaWorldAPI/ndarray` (fork with 55 HPC modules, 880 tests).
+
+**What changes:**
+- `rustynum::Fingerprint` → `ndarray::hpc::fingerprint::Fingerprint<256>`
+- `rustynum::hamming_distance` → `ndarray::hpc::bitwise::hamming_distance_raw`
+- `rustynum::TruthValue` → `ndarray::hpc::bf16_truth::BF16Truth`
+- `rustynum::Cascade` → `ndarray::hpc::cascade::Cascade`
+- BLAS L1-3: `rustyblas::*` → `ndarray::hpc::blas_level{1,2,3}::*`
+
+**What also changes:**
+- lance-graph becomes the Cypher/graph query surface (replacing P1/P3 dead code)
+- lance-graph semiring algebra replaces ad-hoc graph ops in src/graph/spo/
+- rs-graph-llm becomes the orchestration layer (replacing direct crewAI integration)
+
+**Migration order** (from INTEGRATION_PLAN.md Plateau 2):
+1. Add ndarray as path dep (alongside rustynum, not replacing)
+2. Create compat bridge (src/compat/ndarray_bridge.rs)
+3. Migrate src/spo/ to ndarray types — CHECKPOINT: cargo check
+4. Migrate src/nars/ to ndarray types
+5. Migrate src/storage/ BindSpace — CHECKPOINT: cargo test
+6. Remove rustynum deps — only after all tests pass
+
+**DO NOT** start this migration before ndarray builds clean (Plateau 0).
+**DO NOT** migrate BindSpace and SPO simultaneously — SPO first, then BindSpace.
