# 016 — E2E Tests: HMMM → SLURP → UCXL Decision and Load

- Area: test harness under `test/` or `integration_test/`
- Priority: Medium

## Background
We need an end-to-end test proving HMMM discussions generate SLURP events, which in turn publish encrypted UCXL decisions to DHT, retrievable via UCXI. Also needed are load and error-injection tests.

## Scope / Deliverables
- E2E Happy Path:
  - Simulate a HMMM discussion satisfying thresholds; SLURP integrator generates event with UCXL refs; DecisionPublisher stores decision; UCXI GET retrieves content.
- Load Test (lightweight):
  - Batch N events with batching enabled; assert throughput, no duplicates, bounded latency; ensure breaker never opens in healthy scenario.
- Error Injection:
  - Force SLURP 5xx/timeouts → verify backoff/breaker/DLQ (Issue 012) and eventual recovery.
- CI Wire-up:
  - Make tests runnable in CI with mocked DHT/UCXI or local ephemeral services.

## Acceptance Criteria / Tests
- E2E test passes deterministically; artifacts (events + decisions) validate schema; UCXL addresses parse.
- Load test achieves configured throughput without error; error-injection test drains DLQ on recovery.

## Notes
- Reuse existing integration test patterns (e.g., election integration) for harness structure.
