  "campaign": "plot-update-2026-09-11",
  "completed": "2026-09-11",
  "scope": "Fresh updated Instraxis Plot and matched previous-backend controls. Vendor values are historical Instraxis-run references, not rerun in this update. Chart harness measurements, not complete Instraxis Control acquisition, logging or file-loading performance.",
  "statistic": "Nearest-rank p95 combined cycle in milliseconds, pooled across three accepted fresh-process repetitions; lower is better.",
  "timer": "Append/replacement API, range request, library/window processing, UI pumping and DwmFlush. Not physical display latency, FPS or isolated GPU time.",
  "protocol": {
    "runs": "42/42 fresh Instraxis Plot processes accepted: 30 updated and 12 old-backend controls; 14 complete three-run cohorts. No vendor reruns. Historical extended references retain their original 72 chart runs and 6 runtime baselines.",
    "replay": "30 seconds of precomputed immutable input, published every 10 ms, at most 30 requested chart updates/s. All history retained; no ring eviction.",
    "viewport": "Latest 1M points, switching to a historical 10M-point region for the last 250 ms of each 2-second interval.",
    "replacement": "20 complete X/Y replacements per process, cycling three precomputed datasets; includes the first replacement. Selected image captures and settling pauses occur between timed cycles; not an uninterrupted maximum-rate loop.",
    "concurrent": "Replay plus a common application-worker algorithm over an immutable 10M-point region, requested once/s. Not vendor-native analysis or Control analysis capacity.",
    "aggregation": "Latency events pooled across three processes; faster processes can contribute more events. Acceptance, memory and drain values are medians of per-run values.",
    "freshControls": "Fresh old/new controls cover 100M static, 100M +1M/s stream, 100M replacement and 100M concurrent. No fresh previous-backend controls for 10M cases or 100M +100k/s streaming. Within each host type, only the native DLL differs.",
    "correctness": "Eight selected current-source correctness suites passed before timing. All 186 saved checkpoints accepted: 35 directly inspected originals, remaining captures matched by exact hash and fixture/view. Internal independent recomputation checked 4,776 values with zero differences; not third-party certification."
