## 🎓 How Implementers Should Use These Tests

### TDD Workflow

```bash
# 1. Choose a component (start with exo-core)
cd /home/user/ruvector/examples/exo-ai-2025

# 2. Read the relevant test file
cat tests/substrate_integration.rs

# 3. Understand expected API from test code
# Tests show EXACTLY what interfaces are needed

# 4. Create the crate
mkdir -p crates/exo-core
cd crates/exo-core
cargo init --lib

# 5. Implement to satisfy the test
# The test IS the specification

# 6. Remove #[ignore] from test
vi ../../tests/substrate_integration.rs
# Remove: #[ignore]

# 7. Run the test
cargo test --test substrate_integration test_substrate_store_and_retrieve

# 8. Iterate until passing
# Fix compilation errors, then runtime errors

# 9. Verify coverage
cargo tarpaulin --workspace
```

### Running Tests

```bash
# All tests (currently all ignored)
cargo test --workspace

# Specific suite
cargo test --test substrate_integration

# Single test
cargo test test_substrate_store_and_retrieve -- --exact

# With output
cargo test -- --nocapture

# With coverage
./scripts/run-integration-tests.sh --coverage
```

## 📋 API Contracts Defined

The tests define these API surfaces (implementers must match):

### Core Types
```rust
Pattern { embedding, metadata, timestamp, antecedents }
Query { embedding, filter }
SearchResult { id, pattern, score }
SubstrateConfig
```

### Core Traits
```rust
trait SubstrateBackend {
    fn similarity_search(...) -> Result<Vec<SearchResult>>;
    fn manifold_deform(...) -> Result<ManifoldDelta>;
    fn hyperedge_query(...) -> Result<HyperedgeResult>;
}

trait TemporalContext {
    fn now() -> SubstrateTime;
    fn causal_query(...) -> Result<Vec<CausalResult>>;
    fn anticipate(...) -> Result<()>;
}
```

### Main APIs
- `SubstrateInstance::new(backend)` → Substrate
- `substrate.store(pattern)` → PatternId
- `substrate.search(query, k)` → Vec<SearchResult>
- `ManifoldEngine::deform(pattern, salience)` → Delta
- `HypergraphSubstrate::create_hyperedge(...)` → HyperedgeId
- `TemporalMemory::causal_query(...)` → Vec<CausalResult>
- `FederatedMesh::byzantine_commit(...)` → CommitProof

## 🎯 Performance Targets

Tests verify these targets:

| Operation | Target Latency | Test |
|-----------|----------------|------|
| Pattern storage | < 1ms | bulk_operations |
| Similarity search | < 10ms | bulk_operations |
| Manifold deformation | < 100ms | manifold_deformation |
| Hypergraph query | < 50ms | hyperedge_creation_and_query |
| Causal query | < 20ms | causal_storage_and_query |
| CRDT merge | < 5ms | crdt_merge_reconciliation |
| Consensus round | < 200ms | byzantine_consensus |

## 🚀 Next Steps for Project

### For Coder Agents

1. **Start with exo-core**
   - Read: `/home/user/ruvector/examples/exo-ai-2025/tests/substrate_integration.rs`
   - Implement types shown in tests
   - Remove `#[ignore]` and run tests

2. **Then exo-backend-classical**
   - Integrate ruvector crates
   - Implement SubstrateBackend trait
   - Pass substrate tests

3. **Then exo-manifold, exo-hypergraph, exo-temporal, exo-federation**
   - Follow same pattern
   - Tests guide implementation

### For Reviewers

- Verify tests match specification (`specs/SPECIFICATION.md`)
- Verify tests match architecture (`architecture/ARCHITECTURE.md`)
- Verify tests match pseudocode (`architecture/PSEUDOCODE.md`)

### For Project Leads

- Set up CI/CD to run integration tests
- Track progress: # of tests passing / 28 total
- Establish coverage requirements (recommend >80%)
