+# Sovereign Lattice Mesh (SLM)
+
+**Signature:** `Δ9Φ963-SLM-v1.0`  
+**Spec reference:** Biophase7 — Complete Specification Package (Merkle gossip → distributed mycelium → harmonic consensus).
+
+## Components (implementation order)
+
+| # | Module | Path | Role |
+|---|--------|------|------|
+| 1 | Anti-entropy sync | `stack/merkle_sync.py` | `LygoMerkleTree`, `sync_round`, gossip payloads |
+| 2 | Distributed mycelium | `stack/distributed_mycelium_mesh.py` | 12/10 erasure, consistent hash ring, node failure sim |
+| 3 | Harmonic consensus | `stack/harmonic_consensus_mesh.py` | 3/6/9 vortex votes weighted by ethical mass |
+| — | Runtime | `stack/sovereign_lattice_mesh.py` | `SovereignLatticeMesh` — converge, snapshot, gossip |
+
+`LYGOProtocolStack.slm` lazy-loads SLM from federation gossip + peer registry.
+
+## Node API routes
+
+| Method | Path | Purpose |
+|--------|------|---------|
+| GET | `/gossip/root` | Merkle root + badge count |
+| POST | `/gossip/sync` | Level/index sync payload |
+| GET | `/slm/snapshot` | SLM metrics snapshot |
+| GET | `/mycelium/fragment/{id}` | Fragment fetch |
+| GET | `/mycelium/reconstruct/{data_id}` | Threshold reconstruct |
+| POST | `/mycelium/store` | Store payload (12 fragments) |
+| POST | `/consensus/propose` | New proposal |
+| POST | `/consensus/vote` | Cast 3/6/9/-1 vote |
+| GET | `/consensus/result/{id}` | Finalize / status |
+
+Gossip badge ingest updates Merkle: `POST /gossip/badge`.
+
+## Operator tools
+
+```bash
+python tools/merkle_tree.py
+python tools/distributed_mycelium.py
+python tools/consensus_engine.py
+python tools/run_slm_audit.py
+python -m pytest tests/test_slm_mesh.py -q
+```
+
+## Real metrics (audit SLM-09)
+
+- Full SLM audit target: under 1000 ms on maintainer host (`elapsed_ms` in `tests/slm_audit_last_run.json`).
+- Mycelium: at least 10/12 fragments required for reconstruct (`minimum_threshold=10`).
+- Mesh sim converge: 3 rounds default in `SovereignLatticeMesh.converge`.
+
+## Stack integration
+
+```python
+from stack.lygo_stack import deploy_stack
+
+stack = deploy_stack("NODE_A")
+stack.slm.ingest_gossip_badge("NODE_B", {"alignment": "ALIGNED"})
+print(stack.slm.gossip_root())
+```
+
+Bound to P0 Φ-gate and federation gossip — no weakening of Layer 1 sovereignty guards.
