  "Notes": {
    "scope": "Capacity-save source integration, active-reviewer tracking off, screening family only; no HTTP, assignment, SignalR or reviewer-maintenance claim.",
    "controller_boundary": "Current ReviewController resolves durable tracking mode per attempt and selects the plain save when tracking is off. This harness retains the capacity-save repository overload with tracking off, so its p95 is not the current HTTP path or reviewer-maintenance acceptance.",
    "sampling": "Per submission includes source reload, envelope/receipt read, classification and up to three fresh-source save attempts. Attempt timings cover repository save only. Warmup excluded. Same reviewers edit existing decisions after first round.",
    "unknown_commit": "Driver CommandFailed events count UnknownTransactionCommitResult labels; CommitTransaction command starts count actual commit attempts. No fault injection. Other exceptions fail the run.",
    "timing_gate": "Report candidate/baseline p95 overhead against \u003C10%; timing never determines CI correctness on a shared host. Exhaustion remains an observed outcome, not a successful save.",
    "round_trip_counting": "Command counting is opt-in via SYRF_STATS_COUNT_ROUNDTRIPS; it is ON for this run. A CommandStartedEvent subscriber forces the driver to materialize every command document, and the materialized arm issues far more commands than the source-only arm, so the subscriber\u0027s own cost is asymmetric. Run once with it off to get a no-subscriber control timing, and once with it on for the command breakdown. With it off, commands and commit_attempts are recorded as not_counted and no per-command-name record is emitted.",
    "per_attempt_commands": "Per-attempt command counts are recorded only for the single-reviewer cells. With two or more reviewers the submissions run concurrently against one shared counter, so a per-attempt delta would include another reviewer\u0027s commands and is deliberately not claimed.",
