+# Calculet NPU 研究资料归档
+
+本仓库是 2026-08-01 至 2026-08-02 从测试样机采集并在本地验收的 Calculet NPU 研究资料入口，供内网团队持续分析 Runtime、驱动、`llama.cpp`、算子优化、多模型调度和新模型适配。
+
+状态：八个权威主归档完整，合计 `21,078,519,107` 字节；源码历史、Git bundle、模型文件清单和研究报告均已纳入。原始内容的 SHA-256 不因本仓库的分片方式而改变。
+
+## 快速开始
+
+仓库使用 Git LFS。首次使用前安装 Git LFS，然后克隆：
+
+```bash
+git lfs install
+git clone git@192.168.10.248:cogito/calculet-npu-research-archive.git
+cd calculet-npu-research-archive
+./scripts/verify-repository.sh
+```
+
+只想先看报告和源码、不立即下载约 21 GiB 原始归档时：
+
+```bash
+GIT_LFS_SKIP_SMUDGE=1 git clone git@192.168.10.248:cogito/calculet-npu-research-archive.git
+```
+
+随后可按需执行 `git lfs pull --include='archives/<路径>'`。
+
+## 目录
+
+| 路径 | 内容 | 用途 |
+|---|---|---|
+| `reports/` | 30 份研究报告、JSON 和校验工具 | 研究导航、接口契约、调优与实施规格 |
+| `documentation/` | Runtime API 与 VPN 原始 PDF | 官方接口和接入资料 |
+| `source/` | 去除嵌套 `.git` 后的可浏览源码快照 | 直接检索、代码阅读和修改起点 |
+| `history/` | Git bundle、精确仓库 tar、patch、reflog 和主题索引 | 恢复完整提交历史与失败/调优路径 |
+| `archives/` | 八个权威主归档；大文件为 512 MiB 可逆分片 | 灾备、重新解包、原始证据保全 |
+| `checksums/` | 原始归档、分片、模型和 Git 资产校验值 | 完整性复核 |
+| `provenance/` | 原始索引、传输 manifest、日志和完成标记 | 采集与传输审计 |
+| `scripts/` | 重组、校验和 bundle 恢复脚本 | 复现与长期维护 |
+
+## 权威主归档
+
+| 归档 | 字节数 | SHA-256 |
+|---|---:|---|
+| `00-critical-context-20260801.tar.zst` | 8,942,525 | `2ad543697861a386b36604f863acdc161fbfd6552c9cd1e959b1fbe540b524ed` |
+| `01-model-runtime-no-weights-20260801.tar.zst` | 11,253,912 | `5414d91cb4bc3c0e64bf29f7e86fc9cef2e2963ff0c5a5ca6488f008053630b8` |
+| `llama.cpp-full-no-exclusions-fd9bd632.tar.gz` | 264,921,801 | `55d28eb0b72eb8e22627028965912b3a274b76314f8d726f67427a42ee0b2d25` |
+| `baseline-analysis-export-20260801.tar` | 436,398,080 | `ba39aee991c8655324db4326c49a1f32af20ae450a8d07d51f9eac1c60186a4c` |
+| `calculet-container-home-v0.4.8-release.tar.gz` | 740,994,223 | `54fe26018983d293c404b2963db7eb90f70bf9d367eefe64ab36003cc9f9530c` |
+| `calculet-llama-v0.4.8-release.oci.tar` | 1,646,166,016 | `1ad4aba68c6a96cf7f592fdcd8e0c801bf022845aaf71cd49b909abd60365bf3` |

+
+小于等于 512 MiB 的归档直接位于 `archives/`。更大的归档位于同名 `.parts/` 目录，运行以下命令可重组并核对整包哈希：
+
+```bash
+./scripts/reassemble-archives.sh /path/to/output
+```
+
+## 恢复 Git 历史
+
+`source/` 是便于 Gitea 在线浏览的工作树，不把嵌套仓库的 `.git` 目录直接嵌入本仓库。完整对象、分支、标签、reflog 证据和不可达提交保存在 `history/` 的 bundle 与精确仓库 tar 中。
+
+从 bundle 建立独立仓库：
+
+```bash
+./scripts/clone-bundle.sh history/llama.cpp/llama.cpp-all-refs-20260802.bundle /path/to/llama.cpp
+```
+
+## 完整性与已知例外
+
+- 八个主归档在发布前重新核对过 SHA-256 和格式。
+- 七个恢复仓库通过 `git fsck --full --no-reflogs`，五个 bundle 通过 `git bundle verify`。
+- macOS 普通工作树不能精确表达 Linux 大小写碰撞路径及 7 个 overlay whiteout 设备节点；它们在权威 tar 中完整保留。
+- baseline 自带清单对一个 depth500 包含一条过期重复哈希，实际文件匹配其第二条记录；baseline 主归档整包哈希通过。
+- `user2-live-home` 含采集时的 shell 历史、用户配置、测试目录和 rootless Podman 状态。发布前未检出 SSH 私钥、OpenVPN 配置、口令、访问令牌或授权头，但仓库仍应仅在获准的内网团队范围使用。
+
+详细验收依据见 `provenance/完整性验收报告.md` 和 `reports/Calculet-NPU-全部数据下载与验收摘要-20260802.md`。
