# MetaHarness integration gates — ADR-150 Phase 1 MVP.
#
# Three jobs, all fast (subprocess invocations of `npx metaharness`):
#   1. score              — fail if ruflo's own harnessFit drops below 70
#   2. mcp-scan           — fail on any HIGH-severity MCP finding in ruflo
#   3. router-compat      — exercise `@metaharness/router.Router` constructor;
#                            catches breaking API changes before publish
#
# Triggers on changes that could move any of these signals:
#   - the ruflo-metaharness plugin
#   - the @metaharness/router optional dep version in v3/@claude-flow/cli
#   - the v3 ruvector router-trajectory + neural-router source
#   - this workflow file
