Summary
The test-support group gives repository tests deterministic, keyless ways to exercise the real product. It includes Loader application harnesses, session-log snapshot adapters, a replay LLM plugin, and a scriptable OpenAI-compatible fault server. Each package is support-tier infrastructure; a package moves out of this group when it gains a product contract and product consumers.
