  "limitations": [
    "Diagnostic instrumentation and headers add overhead; not a production latency benchmark.",

    "Per-profile resource snapshots include untimed worker connection primers.",
    "Count selectivity follows recorded start range; compare it explicitly before interpreting other experiments.",
    "qdrant.send_headers includes pool/socket wait, backend execution and scheduling; receive_body is remaining response delivery.",
    "response.json_encode covers es_ok serialization only; response Value construction is inside search.after_join.",
    "Phase durations are wall intervals, not CPU cost; preserve per-request relationships instead of summing categories.",
    "Intervals overlap; do not sum backend durations or subtract independently measured percentiles.",
    "search.after_join includes fallback work on other request shapes; here the ordered fast path is required."
