Implementation Workflow

For Implementers

1. Choose a component (recommend: exo-core → exo-backend-classical → exo-manifold → exo-hypergraph → exo-temporal → exo-federation)

2. Read the tests to understand expected behavior

3. Implement the crate to satisfy test requirements

4. Remove #[ignore] from test

5. Run test and iterate until passing

6. Verify coverage (target: >80%)

Example: Implementing exo-core

# 1. Read test
cat tests/substrate_integration.rs

# 2. Create crate
cd crates/
cargo new exo-core --lib

# 3. Implement types/methods shown in test
vi exo-core/src/lib.rs

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

# 5. Run test
cargo test --test substrate_integration test_substrate_store_and_retrieve

# 6. Iterate until passing

Dependencies Required

Tests assume these dependencies (add to Cargo.toml when implementing):

[dev-dependencies]
tokio = { version = "1", features = ["full", "test-util"] }
env_logger = "0.11"
log = "0.4"

[dependencies]
# Core
tokio = { version = "1", features = ["full"] }
serde = { version = "1", features = ["derive"] }

# Manifold (exo-manifold)
burn = "0.14"

# Hypergraph (exo-hypergraph)
petgraph = "0.6"
ruvector-graph = { path = "../../crates/ruvector-graph" }

# Temporal (exo-temporal)
dashmap = "5"

# Federation (exo-federation)
ruvector-raft = { path = "../../crates/ruvector-raft" }
kyberlib = "0.5"

Success Criteria

Integration test suite is considered successful when:

• ✅ All 28 tests can be uncommented and run
• ✅ All tests pass consistently
• ✅ Code coverage > 80% across all crates
• ✅ Performance targets met
• ✅ No flaky tests (deterministic results)
• ✅ Tests run in CI/CD pipeline
• ✅ Documentation kept up-to-date

Next Steps

1. Implementers: Start with exo-core, read docs/INTEGRATION_TEST_GUIDE.md
2. Reviewers: Verify tests match specification and architecture
3. Project Leads: Set up CI/CD to run tests automatically
4. Documentation Team: Link tests to user-facing docs
