# 009 — Integration Tests: UCXI + DHT Encryption + Search

- Area: tests under `pkg/ucxi/`, `pkg/dht/`, e2e harness
- Priority: Medium

## Background
There are good unit tests across modules, but no end-to-end UCXI HTTP tests through encrypted DHT and back, nor tests proving address-based search works with full UCXL strings.

## Scope / Deliverables
- Add UCXI HTTP tests using httptest:
  - PUT content at valid UCXL addresses (with temporal), GET back exact bytes.
  - DELETE + 404 on subsequent GET.
- Encrypted DHT path tests (mocked DHT ok): assert encrypt/decrypt with role.
- Search tests that insert multiple cached entries and verify agent/role/project/task filters.

## Acceptance Criteria / Tests
- `go test ./...` passes and includes new UCXI/DHT e2e cases.
- Invalid addresses during PUT/GET return UCXL-400 codes (after Issue 004).

## Notes
- Consider a small fake DHT interface to keep tests hermetic.
