+# OpenPI 0.3.0、Pi 与 OMP 的 54-cell ARM64 派生诊断
+
+## 状态与范围
+
+本报告整理 Issue [#46](https://github.com/openpi-dev/openpi/issues/46) 中已经公开的实验收据。它记录的是 Linux ARM64 VM 上运行的 Terminal-Bench 2.1 source-build-derived 诊断，**不是 Terminal-Bench 官方成绩、排行榜成绩或正式提交**。
+
+实验矩阵为：
+
+```text
+2 models × 3 tasks × 3 repeats × 3 harnesses = 54 cells
+```
+
+模型是 `seal/glm-5.3` 和 `seal/gpt-5.6-luna`；Harness 是 Bare Pi、Pi + OpenPI 与 OMP；任务是 `git-leak-recovery`、`sqlite-db-truncate` 和 `cancel-async-tasks`。
+
+本报告只转录已公开的结果，不把小样本观察写成通用排名，也不声称 OpenPI 相对 Bare Pi 有普遍质量或速度提升。
+
+## 冻结条件
+
+| 项目 | 值 |
+| --- | --- |
+| Pi | `@earendil-works/pi-coding-agent 0.84.2` |
+| OpenPI | [`@tt-a1i/openpi 0.3.0`](https://github.com/openpi-dev/openpi/releases/tag/v0.3.0) |
+| OMP | `@oh-my-pi/pi-coding-agent 17.2.12` |
+| Bun | `1.3.14` |
+| Harbor | `0.20.0` |
+| Container runtime | Podman server `6.0.2`，Linux ARM64 VM |
+| Task source | Terminal-Bench 2.1 ARM64 source-build-derived，commit `d1f1920f2d817a831f466d0ff363ef795a9a3b00` |

+| `seal/gpt-5.6-luna` | `high` |
+
+## 结果
+
+### GLM-5.3
+
+结果使用 `pass / fail / indeterminate`。Wall 包含 indeterminate 等待时间。
+
+| Harness | 结果 | Wall | Provider tokens | Physical POST |
+| --- | ---: | ---: | ---: | ---: |
+| Bare Pi | 7 / 1 / 1 | 2,647.724s | 249,625 | 94 |
+| OpenPI | 7 / 2 / 0 | 1,107.098s | 331,851 | 87 |
+| OMP | 7 / 2 / 0 | 1,081.746s | 2,176,017 | 106 |
+
+| Task | Bare Pi | OpenPI | OMP |
+| --- | ---: | ---: | ---: |
+| Git leak recovery | 3 / 0 / 0 | 3 / 0 / 0 | 3 / 0 / 0 |
+| SQLite truncate | 3 / 0 / 0 | 3 / 0 / 0 | 3 / 0 / 0 |
+| Cancel async tasks | 1 / 1 / 1 | 1 / 2 / 0 | 1 / 2 / 0 |
+
+可支持的效率观察：OpenPI 与 OMP 都是 7 pass；OpenPI 使用的 provider tokens 是 OMP 的 15.3%，少 84.7%。OpenPI 相对 Bare Pi 多 32.9% tokens，因此本批次不能声称 OpenPI 比原生 Pi 更省 token。Bare Pi 的一次 indeterminate 与 cancel 的 process-group 行为有关，不能用总 wall 宣称稳定提速。
+
+### GPT-5.6 Luna
+
+该路线没有返回可用 token usage，因此只比较 verifier、物理请求数和 wall，不作 token 或成本结论。
+
+| Harness | 结果 | Wall | Physical POST | Logical attempts | 额外物理 POST |
+| --- | ---: | ---: | ---: | ---: | ---: |
+| Bare Pi | 7 / 2 / 0 | 1,129.885s | 43 | 43 | 0 |
+| OpenPI | 7 / 2 / 0 | 1,151.213s | 46 | 46 | 0 |
+| OMP | 4 / 5 / 0 | 1,803.368s | 110 | 92 | 18 |
+
+| Task | Bare Pi | OpenPI | OMP |
+| --- | ---: | ---: | ---: |
+| Git leak recovery | 3 / 0 / 0 | 3 / 0 / 0 | 3 / 0 / 0 |
+| SQLite truncate | 3 / 0 / 0 | 3 / 0 / 0 | 1 / 2 / 0 |
+| Cancel async tasks | 1 / 2 / 0 | 1 / 2 / 0 | 0 / 3 / 0 |
+
+可支持的效率观察：OpenPI 与 Bare Pi 都是 7/9；OpenPI wall 比 Bare Pi 高 1.9%，没有提速证据。OpenPI 相对 OMP 多 3 pass，物理模型请求少 58.2%，总 wall 低 36.2%。OMP 的 110 个物理 POST 对应 92 个已完成 logical attempts，18 个 provider 重试没有从开销中隐藏。
+
+## 完整性与安全收据
+
+两组运行记录均满足：
+
+- 27/27 个 Pi/OpenPI/OMP cell 落盘且身份唯一；
+- 最终冻结源校验通过；
+- retained artifact credential scan：0 missing roots、0 credential leak、0 scan failure；
+- 真实 provider key 未注入 candidate；
+- 全局并发为 1，所有 cell 按冻结 Latin-square 严格串行执行。
+
+运行身份：
+
+| 模型 | Lock fingerprint | Receipt |
+| --- | --- | --- |
+| GLM-5.3 | `sha256:037179456f3223457e428b9d5543911144b045bcea7ee7127728b27dd735780e` | `completed_with_indeterminate` |
+| GPT-5.6 Luna | `sha256:00b9db64606832521df7f853d63d5e50d1e6754920e0ac51e1b32c2aacc4866c` | `completed_with_indeterminate` |
+
+Evidence controller 还记录了 provider 物理重试：当 `physical POST < logical attempts` 时 fail closed；非负差值记录为 `unattributedProviderPostRequests`。
+
+## 结论边界
+
+这批结果支持以下窄结论：
+
+1. 在两个完整模型批次中，OpenPI 与 Bare Pi 的通过数都是 7/9；Git 与 SQLite 两类任务合计都是 12/12。
+2. 在这组普通 Terminal 任务中，OpenPI 保持了原生 Pi 的通过数；不同任务的耗时方向不一致，因此不作相对 Pi 的稳定速度结论。
+3. 相对 OMP，GLM-5.3 批次观察到相同 pass 数下更低的 token 使用；Luna 批次观察到更多 pass、更少物理请求和更低 wall time。样本很小，不能外推为总体排名。
+4. 这些任务没有专门要求 Subagent 或 Workflow，因此结果不能证明 OpenPI 编排能力的收益。
+
+## 验证与复现边界
+
+本报告对应的可检索、无凭据边界收据见 [receipts/openpi-issue-46-arm64-54-cell-v1.md](receipts/openpi-issue-46-arm64-54-cell-v1.md)。收据包含压缩后的任务结果账本、冻结身份、汇总指标和安全边界，可重算本报告的 pass/fail/indeterminate 汇总；原始 JSONL、Session、日志、candidate workspace 和凭据不随仓库发布。当前记录仍为 `draft`，因为原始证据包尚未提供独立复核入口。
+
+Issue #46 记录的原始验证为：
+
+- controller 定向 Node tests：23 pass，1 个环境用例 skip；
+- 项目全量 Node tests：719/719；
+- Vitest：29/29；
+- `bun run check`：format、lint、typecheck 通过，typecheck 仅有既存 Effect advisory warnings。
+
+本仓库当前提交落地的是报告和公开收据，不包含每个 cell 的原始 artifact；因此报告的可追溯锚点是 Issue #46、冻结版本、任务 commit、调度 hash、lock fingerprint 和安全收据。若要宣称可独立复算或官方成绩，仍需另行提供原始 artifact 包、运行脚本和相同环境。
+
+下一轮实验应扩大任务集，并预注册会自然触发 Subagent/Workflow 的多文件任务，将能力采用率、质量与成本分开报告。

+# Bounded evidence receipt: Issue #46
+
+This receipt is the small, credential-free evidence boundary for the 54-cell
+ARM64 diagnostic reported in Issue [#46](https://github.com/openpi-dev/openpi/issues/46).
+It is versioned with the report and identified by `receipt-id` above.
+
+The ledger below records the three-repeat outcome for each model, harness, and
+task. Summing `pass`, `fail`, and `indeterminate` by model and harness
+reproduces the report's 7/9, 4/9, and related result totals. Aggregate wall,
+usage, and request counts are retained separately because the public source
+only exposed those metrics at harness level.
