Add unit tests for schema changes + +**Deliverable:** Trust Packs can store and serialize policy aliases. + +### Phase 2: Pattern Matching (Day 1-2) + +1. Implement `glob_match()` function +2. Add `lookup_with_policy_aliases()` to ConceptIndex +3. Write comprehensive test suite for pattern matching +4. Handle edge cases (empty patterns, invalid syntax) + +**Deliverable:** Pattern matching algorithm works correctly. + +### Phase 3: Scan Integration (Day 2) + +1.

Integration Tests vs Unit Tests + +**Decision:** Use integration tests in `tests/` directory rather than unit tests. + +**Rationale:** +- UAT scenarios test end-to-end flows (API → Handler → Query Engine → Lens → Response) +- Requires running API server with real database +- Mimics actual user workflows +- Easier to map to UAT markdown files + +### 2. Blocking HTTP Client + +**Decision:** Use `reqwest::blocking::Client` instead of async client. + +**Rationale:** +- Simpler test code (no async/await complexity) +- Sequential execution matches UAT workflow +- Easier to debug and reason about +- Adequate performance for test scenarios + +### 3. Dummy Signatures + +**Decision:** Use placeholder signatures (`0000...`) instead of generating real Ed25519 signatures. + +**Rationale:** +- Faster test execution +- Simpler test setup +- API may have test mode that skips signature verification +- Can upgrade to real signatures if needed + +**Risk Mitigation:** Document this as a known issue in execution plan. + +### 4. Sleep-Based Ingestion Wait + +**Decision:** Use `std::thread::sleep()` to wait for assertion ingestion instead of polling. + +**Rationale:** +- Simple and reliable +- Sufficient for test scenarios (2-3 seconds) +- No additional complexity from polling logic + +**Future Enhancement:** Add polling with timeout for more robust tests. + +## API Contract Validation + +### Endpoints Verified + +All endpoints referenced in UAT scenarios have been verified to exist: + +| Endpoint | Method | Purpose | Status | +|----------|--------|---------|--------| +| `/v1/assert` | POST | Create assertions | ✅ Exists | +| `/v1/skeptic` | GET | Skeptic Lens query | ✅ Exists | +| `/v1/layered` | GET | Layered Consensus query | ✅ Exists | +| `/v1/query` | GET | Generic query | ✅ Exists | +| `/v1/health` | GET | Health check | ✅ Exists | +| `/api-docs/openapi.json` | GET | OpenAPI spec | ✅ Exists | + +### DTOs Validated + +All data structures match API contracts: + +| DTO | Matches API | Source | +|-----|-------------|--------| +| `CreateAssertionRequest` | ✅ | `stemedb-api/src/dto/create.rs` | +| `CreateResponse` | ✅ | `stemedb-api/src/dto/responses.rs` | +| `SkepticResponse` | ✅ | `stemedb-api/src/dto/skeptic.rs` | +| `LayeredQueryResponse` | ✅ | `stemedb-api/src/dto/responses.rs` | +| `ObjectValue` | ✅ | `stemedb-api/src/dto/object_value.rs` | + +## Execution Readiness + +### Build Status + +``` +✅ stemedb-ontology builds successfully +✅ Library tests pass (55 passed, 0 failed) +✅ UAT integration tests compile +✅ API validation script is executable +``` + +### Test Execution Commands + +```bash +# Individual scenarios +STEMEDB_API_URL=http://localhost:18180 cargo test --test consumer_health_uat uat_glp1_muscle_loss_contradiction -- --ignored --nocapture + +STEMEDB_API_URL=http://localhost:18180 cargo test --test consumer_health_uat uat_gastroparesis_multi_source -- --ignored --nocapture + +STEMEDB_API_URL=http://localhost:18180 cargo test --test consumer_health_uat uat_layered_consensus -- --ignored --nocapture + +# All scenarios +STEMEDB_API_URL=http://localhost:18180 cargo test --test consumer_health_uat run_all_uat_scenarios -- --ignored --nocapture +``` + +## Known Issues & Limitations + +### 1.

Assertion Ingestion Delay + +**Issue:** Assertions go through WAL → Ingest Worker → Index Store. + +**Current Approach:** `sleep(2-3 seconds)` after ingestion. + +**Risk:** Race conditions if ingestion is slower than expected. + +**Mitigation:** +- Increase sleep duration +- Add polling for assertion availability +- Use synchronous ingestion for tests + +### 3.
