Windows Server 2025 Datacenter; Xeon Platinum 8573C, 4 vCPU; NTFS; Node 26.12.1; Git for Windows 2.56.1; WinDefend running, DisableRealtimeMonitoring=False.
One shared depth-1 32,282-file clone on main, origin/main points at benchmark HEAD, no configured branch upstream.
Fresh database per batch; no live data copied; all paid providers disabled.
Order: base, head, head, base. Each batch: 2 excluded warm-ups, then 9 measured replay turns.

Real server from installed source checkout: node apps/server/src/bin.ts --base-dir <fresh-home> --dev-url http://localhost:15733 --host 127.0.0.1 --port 15734 --no-browser
T3CODE_DEV_SEED=0. Add benchmark project through CLI.
For each iteration: thread start <repo> "turn N" --provider devReplay --model todo-list --wait --json; await the persisted finalize span; thread show --json; call vcs.refreshStatus {cwd:<repo>,localOnly:true} over authenticated WebSocket; read clean Git status.
Finalization timing comes from real server spans; RPC and CLI timing use performance.now(). Server setup, CLI show, trace flush and raw git validation are outside the timed actions.

Milliseconds; warm-ups are preserved below but excluded from summary.
