  "method": "Each profile independently uses old,new,new,old order; all three engines interleaved in each round. 10000 retained documents, 200 requests, 3 trials, 40 warmups, concurrency 1 and 8. No builds or ingestion during timing. Every response strictly checked. All trials retained.",
  "notes": [
    "Each round records exact image IDs and resource caps. Candidate image was built from the production source subsequently committed as b537bf9.",
    "Profiles change track_total_hits identically for every engine; comparisons across profiles are not endpoint-only comparisons.",
    "Native engines remain faster in all ten candidate workload/concurrency cells. No memory or ingestion claim is made from these read-only rounds.",
    "Benchmark corpus was populated before the wait-query-parameter correction. These timings occur after all documents are visible and do not measure write acknowledgment."
