BASE Commit: 8bd7f466ccdb3f53e46aed9ec084c015f45811d6 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 --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 "turn N" --provider devReplay --model todo-list --wait --json; await the persisted finalize span; thread show --json; call vcs.refreshStatus {cwd:,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. batch iteration warmup rpc_ms finalize_ms local_refresh_ms cli_wall_ms git_processes full_untracked_scans untracked_scan_ms 0 1 True 1140.11 2771.05 1418.40 7778.16 25 1 310.18 0 2 True 1132.46 2670.68 1288.81 7048.20 19 1 312.30 0 3 False 1120.99 2589.27 1298.22 7126.96 19 1 311.28 0 4 False 1152.25 2667.61 1280.77 7008.26 19 1 310.26 0 5 False 1155.02 2687.30 1306.99 7340.50 19 1 318.12 0 6 False 1156.82 2970.82 1554.20 7419.51 30 1 326.63 0 7 False 1128.83 2742.92 1406.07 7151.23 19 1 311.21 0 8 False 1149.88 2683.09 1315.16 7060.47 19 1 318.79 0 9 False 1140.08 2705.20 1305.57 7199.29 19 1 318.42 0 10 False 1154.90 2676.77 1324.01 7063.06 19 1 319.89 0 11 False 1166.45 2766.05 1325.17 7329.21 19 1 322.06 3 1 True 1128.13 2735.52 1421.84 7620.95 25 1 301.45 3 2 True 1116.49 2553.69 1263.36 6997.58 19 1 309.84 3 3 False 1196.17 2606.19 1293.93 7196.84 19 1 314.96 3 4 False 1133.81 2685.39 1280.33 7096.77 19 1 313.22 3 5 False 1133.20 2724.20 1295.58 7226.92 19 1 329.44 3 6 False 1169.32 2829.80 1499.46 7155.97 30 1 315.43 3 7 False 1141.13 2724.70 1290.69 7313.54 19 1 315.30 3 8 False 1131.98 2892.98 1404.16 7235.11 19 1 335.97 3 9 False 1148.42 2650.03 1312.66 7032.12 19 1 312.35 3 10 False 1143.33 2666.58 1315.13 7146.59 19 1 321.53 3 11 False 1146.97 2793.84 1360.48 7108.80 19 1 323.48 Summary: { "samples": 18, "refreshRpcMs": { "median": 1147.6927500000456, "min": 1120.9853000000003, "max": 1196.1674000000348, "spread": 75.18210000003455 }, "localRefreshMs": { "median": 1313.8973500000002, "min": 1280.3299, "max": 1554.2033, "spread": 273.87339999999995 }, "finalizeMs": { "median": 2696.2471, "min": 2589.2749, "max": 2970.8185, "spread": 381.54359999999997 }, "wallMs": { "median": 7153.602999999988, "min": 7008.2629000000015, "max": 7419.50959999999, "spread": 411.2466999999888 }, "gitProcesses": { "median": 19.0, "min": 19, "max": 30, "spread": 11 }, "gitMs": { "median": 1786.8472000000002, "min": 1746.7830000000004, "max": 3006.5184000000004, "spread": 1259.7354 }, "fullUntrackedScans": { "median": 1.0, "min": 1, "max": 1, "spread": 0 }, "batches": { "0": { "refreshRpcMs": 1152.254399999998, "localRefreshMs": 1315.1575, "finalizeMs": 2687.2975, "wallMs": 7151.232099999994 }, "3": { "refreshRpcMs": 1143.3347000000067, "localRefreshMs": 1312.6617, "finalizeMs": 2724.1961, "wallMs": 7155.973899999983 } }, "statusEqualWithinSide": true, "allFinalizationsSucceeded": true, "allCliRunsCompleted": true, "threadStatuses": [ "completed" ], "assistantMessagesEqualWithinSide": true } Status returned identically on every measured run: { "isRepo": true, "sourceControlProvider": { "kind": "github", "name": "GitHub", "baseUrl": "https://github.com" }, "hasPrimaryRemote": true, "isDefaultRef": true, "refName": "main", "hasWorkingTreeChanges": false, "workingTree": { "rootPath": "", "files": [], "insertions": 0, "deletions": 0 }, "branchChanges": { "baseRef": "origin/main", "insertions": 0, "deletions": 0 }, "hasUpstream": false, "aheadCount": 0, "behindCount": 0, "aheadOfDefaultCount": 0, "pr": null } All CLI runs and thread reads completed; all finalization spans succeeded.
