Why?

Verify the List RPC added in #795 against the real gRPC service and MySQL, while keeping read-contract tests independent of asynchronous ingestion workflows.

What?

Added

• List coverage for pagination and timestamp ties, time-window defaults and boundaries, queue isolation, unknown acceptance times, and invalid requests/tokens.
• Assertions in existing ingest workflows that List exposes lifecycle summaries, deduplication preserves acceptance time, and acceptance time matches request history.
• RFC update marking E2E coverage complete.

Refactored

• Move ingest scenarios from suite_test.go into ingest_test.go; keep setup/teardown and health checks in the suite, List scenarios in list_test.go, and reusable helpers in harness_test.go. This keeps infrastructure separate from behavior and makes each group easier to review.
• Seed List fixtures through storage interfaces on dedicated queues. This makes edge cases deterministic and lets List tests run without relying on ingest tests or pipeline timing.
• Remove transient queue-message-count assertions and use durable acknowledged offsets to verify processing. A consumer can acknowledge and garbage-collect a message before a test counts it.

No production behavior, API, or schema changes.

Test Plan

• Full Stovepipe E2E suite passed.
• List-only scenarios passed twice without running ingest tests.
• Stovepipe/service unit tests and repository formatting, lint, tidy, and Gazelle checks passed.
• Internal validator lint/coverage checks could not complete in this OSS workspace; coverage requires a missing .arcconfig.

Revert Plan

Revert this test and documentation change; runtime behavior is unchanged.
