# promtool unit tests for platform/vuln-scanner/alerts.yaml (R-VULN-06).
#
# Found by platform/monitoring/tests/run.sh through the COMPANION convention. Run just this file with
#   platform/monitoring/tests/run.sh platform/vuln-scanner/alerts.promtool-test.yaml
#
# Each rule is pinned both ways. VulnScanStale and VulnTriageBotSilent additionally pin the two cases
# the spec names by hand: the metric ABSENT must FIRE, and a metric that vanishes must RE-FIRE.
# conformance/tests/l0-static/vuln-alerts-unit-tested reads this file and fails if any of those cases
# is removed.
#
# Timestamps: promtool evaluates from t=0, so a timestamp series can equal its own evaluation time
# with `0+60x<N>` at a 1m interval (time() - value == 0: fresh).
