# Project gate for the MCP-health sidecar (WIN-033/WIN-040 review follow-up).
#
# The sf-mcp-proxy plugin loads GLOBALLY, so `--probe` (and the live bridge) can
# be launched from any cwd. writeHealthSidecar must only persist into a Salesforce
# project (cwd has sfdx-project.json); otherwise it litters `.sf/mcp-health` into
# arbitrary directories. This asserts both directions against the committed bundle:
#   1. no sfdx-project.json  -> --probe writes NO .sf/ dir (still prints its JSON line)
#   2. with sfdx-project.json -> --probe DOES write the sidecar
#
# Run: bash plugins/builder/salesforce-development/scripts/test/mcp-health-project-gate.test.sh
