Experiment design 5 and 7 for the harness VM (10.20.0.11): vm/harness/apply.sh pulls the secrets from Secret Manager, compose runs runner:de076a7, measure-db, blackbox, Alloy (probe_success -> Mimir) and k6 under the campaign profile. Scenario files C-K1..X-M2 are loaded by the runner. Harness ClusterRole gains replicasets get/list for rollout undo.

// Background load of experiment design 5.5: constant-arrival-rate 20 rps, /api/orders 70% and /api/price/{item} 30%.

// Thresholds mirror the SLO (p95 < 500ms, failures < 1%); a breach makes k6 exit non-zero at the end of the run
|
|
// (the SLO verdict itself is the harness judge's Mimir query, design 4.2).
