name: conformance-weekly

# Runs the MCP conformance suite weekly against the latest
# @modelcontextprotocol/conformance release. The on:pull_request pipeline
# pins to whatever version is available at PR time; this schedule catches
# upstream releases that add scenarios between PRs.
#
# It also scores each run and publishes the client/server pass-rate as
# shields.io endpoint JSON to the orphan `badges` branch (consumed by the
# README); that branch is created on the first run.
