# Post-setup smoke test — confirms the stack is healthy before you start using it.
#
# Runs four checks, each short-circuits on failure with an actionable hint:
#   1. Server responds on /v1/models
#   2. Genesis patches applied cleanly (tool_call fix is the fragile one)
#   3. Basic text completion works (Paris sanity)
#   4. Tool calling works end-to-end (request includes tools → response has tool_calls[])
#
# If check 4 fails but checks 1-3 pass, your Genesis tool_call patch didn't apply
# and you're on a vLLM nightly that drifted past our pinned digest. See the README
# troubleshooting section.
#
# Env vars (optional):
#   URL          Override endpoint. Default: http://localhost:8020
#   MODEL        Served model name. Default: qwen3.6-27b-autoround
#   CONTAINER    Docker container name for log scraping. Default: vllm-qwen36-27b

# and the canonical "apply_all elapsed:" anchor fires LAST. Reported by
# @troymroberts in club-3090#25 and refined per @JusefPol in club-3090#29.
