Run a k6 script from the consuming repo against a target URL exported as BASE_URL with a checksum-verified k6 binary. The script's thresholds are the gate: k6 exits 99 when one is crossed and the step fails after the summary is rendered. summary.py turns the --summary-export JSON into a job summary (requests, rate, p95 and max latency, error rate, checks, every threshold) and step outputs. load-test.yml wraps the composite and keeps the summary JSON as an artefact. docs/examples/k6/stac-search.js is a STAC collections and search script with thresholds. CI checks summary.py against recorded summaries, then runs the composite against a local static server once passing and once with an impossible p95 threshold that must fail.
