| # MSE Validation |
|
|
| Curated tabular validation subset for the distributional synthetic replay generator used in the AgentPerfBench submission. |
|
|
| This directory intentionally does **not** store raw runner JSON payloads. The Hugging Face dataset keeps the loadable tables and notes; raw aggregate and per-turn JSON artifacts remain in the R2 archive referenced by `raw_json_r2_uri` and `per_turn_json_r2_uri` in `summary.parquet` / `manifest.csv`. |
|
|
| R2 archive root: `s3://agent-bench/bench_mse/` |
|
|
| ## Files |
|
|
| - `summary.parquet`: one row per aggregate validation run, including R2 URIs for raw JSON provenance. |
| - `manifest.csv`: human-readable copy of the summary table. |
| - `fidelity_deltas.csv`: paired MSE-vs-real median deltas by turn-depth bin and metric. |
| - `notes/`: session notes documenting the debugging process and morphology/prefix-cache findings. |
|
|
| ## Main Validation Stages |
|
|
| | Stage | Role | |
| | --- | --- | |
| | `prefix_aware` | Final SWE-bench proof: code-morph filler plus APC-aligned 1024-token shared prefix. | |
| | `apc_off_v2` | Ablation with prefix caching disabled. | |
| | `morphology` | Code-morph filler without shared prefix. | |
| | `source_locked_baseline` | Source-locked English-filler baseline. | |
| | `paper_terminalbench` | Clean TerminalBench validation. | |
| | `paper_swe_noise_*` / `paper_swe_c20` | Initial SWE-bench paper validation and repeat/noise-floor runs. | |
|
|
| ## Supplementary Stages |
|
|
| | Stage | Role | |
| | --- | --- | |
| | `option2_no_replacement` | No-replacement sampling progression runs. | |
| | `high_concurrency` | C=100 saturation/debug runs; not used as the main fidelity claim. | |
|
|
| ## Headline SWE-Bench Cascade |
|
|
| The key diagnostic comparison is turn 10-19 E2EL median error for source-locked SWE-bench C=5: |
|
|
| | Condition | Turn 10-19 E2EL delta | |
| | --- | ---: | |
| | APC on, English filler, source-locked | +45.5% | |
| | APC on, code-morph filler, no shared prefix | +31.1% | |
| | APC off, code-morph filler, no shared prefix | +11.7% | |
| | APC on, code-morph filler, 1024-token shared prefix | -3.2% | |
|
|
| This supports the paper claim that distributional replay for agentic serving must match both token statistics and serving-visible prefix structure. Token-count matching alone is insufficient for deep SWE-bench turns; code morphology and APC-aware shared prefix structure close the residual gap. |
|
|
| ## Filter Rule |
|
|
| Main rows satisfy: |
|
|
| - paired MSE + real trace replay, |
| - H100 / Llama-3.1-8B / vLLM, |
| - profile in `swebench-multiturn-short` or `terminalbench-multiturn-short`, |
| - request success rate at least 0.75, |
| - stage in `prefix_aware`, `apc_off_v2`, `morphology`, `source_locked_baseline`, `paper_terminalbench`, or `paper_swe_noise`. |
|
|
| Excluded from the main table: |
|
|
| - smoke tests, |
| - older broad validation sweeps before the final generator framing, |
| - A100 real-only validation runs, |
| - the superseded non-v2 APC-off run, |
| - Python caches and temporary source-session files. |
