  "notes": [
    "These are fresh-D1 live-network runs using the same built package, pinned runtime, config, and 100x20x3 scheduling limits. A rate-limited intermediate run was discarded before this pair was retained.",
    "The source workloads were closely matched: fetched records differed by 1,564 (0.185%) and source requests differed by 18 (0.104%). Neither retained run received HTTP 429 responses.",
    "The validated run finished 4.95 seconds sooner, but this is not a validation speedup: it rejected 12,291 records and therefore performed materially fewer canonical and derived writes. A deterministic replay fixture is required to isolate validation CPU cost.",
    "Accepted-record throughput was 516.22/s with validation and 589.37/s without it. Peak RSS was 85,920 KiB higher in the validated process; treat one live-run memory sample as directional rather than a stable bound.",
    "CID verification found no mismatches, encoding failures, or missing authoritative CIDs."
