PR #328 增量静态评审(当前 head 7e3b2e4c):有 4 项需区分为决策边界与实现风险,详见 inline。
- 决策边界:#273 的 owner 决策(2026-10-31)将 R6 明确保留讨论,尚未接受 512 KiB / 2 MiB 数字阈值。此次 PR 的治理声明不能直接代替 owner 接受。
- 实现风险:检查器在 base diff 读取失败时可能静默放行;按修改文件完整尺寸累计却称“net addition”;外置资产 URL 仅校验 HTTPS 前缀,不足以证明真实 GitHub Release 资产。
- 本轮只读检查真实 4 文件 diff、当前 main、#273 原决策及 7 个新增单测的代码;没有运行任何测试或下载/访问资产。CI/单测声明与实际生效的策略、外部可访问性分开判断。本 COMMENT 仅供原 owner/作者处理,不是新门禁、合入授权或目标验收。
评审版本及范围
Head: 7e3b2e4ca3c0a518d1e22c005e96aa85c1e1903d; base: ebdbf5af00c94f228b504a3f4d813aad0b63840c. Files: tools/check_evidence_budget.py, tests/test_evidence_budget.py, .github/workflows/ci-ready.yml, docs/agent-collaboration.md. Relevant existing decision: #273 R6 (keep open for discussion). No model, hardware, paid or software execution.
| 1. **Scope:** identify requirements, exclusions, owner and relevant dependencies. The accountable agent tracks Issue-level criteria and delegates bounded work; PR readiness and Issue completion are reported separately. Keep each PR a coherent delivery slice; small follow-ups may reuse an Issue. | ||
| 2. **Isolation:** concurrent writers use separate working directories/indexes and private scratch files. Branch names alone are insufficient. Inspect staged/committed content and coordinate shared IDs, schemas and interfaces. | ||
| 3. **Evidence:** link checks to actual checked content and relevant environment/test definitions. Distinguish passed, failed, cancelled, skipped, timed-out and not-run. H/B/T—reviewed head, assessed base, tested content—may come from existing records, not mandatory worksheets. | ||

H/B/T—reviewed head, assessed base, tested content—may come from existing records, not mandatory worksheets. Tracked evidence files are bounded by a 512 KiB per-file budget and a 2.0 MiB per-PR net addition budget. Larger raw artifacts (traces, weights) must be hosted as GitHub Release assets and registered in `tools/evidence_inventory.json` with an accessible HTTPS URL, SHA-256 digest, byte count, and retention owner. The ready lane's `evidence-budget` job reports violations. |

[P2|待决规则不宜先写成现行治理约束] #273 的原 owner 决策明确 R6 为 “Keep open for discussion”,特别保留 byte budgets 与 #113/#51 的归档策略待定;目前的新交付/认领评论来自 PR 作者,不是 owner 接受数字阈值的记录。但这里已将 512 KiB / 2 MiB 和必须外置 Release 资产写成已生效工作规则,PR 描述还称“Accepted scope”。建议先表述为待审 R6 提案并请原 owner 明确阈值、适用范围及报告性/约束性后再确定规则文本;不以本评审意见替 owner 做决策。

[P2|显式 base 比对失败时静默放行] Ready job 调用 --base "$BASE_SHA";若 git diff <base>...HEAD 因基准不可用/仓库错误失败,这里退化为 git status --porcelain。CI 的干净 checkout 通常为空,于是超预算的 PR 可被判断为 0 字节并以 0 退出,而不是报告“无法核验”。建议 --base 模式对 diff 错误明确返回非成功/INCONCLUSIVE 的诊断,仅无 --base 的本地模式才检查工作树;增加无效 base 的子进程负例测试。这是静态故障路径推断,未实际触发 CI。

[P2|“net addition”与计算口径不符] 上游 --diff-filter=ACM 选出所有修改文件,再把每个文件的最终总字节数加进 total_evidence_bytes,并标为 evidence net addition。例如修改一个既有 500 KiB 证据文件的 1 字节,就计入 500 KiB;对多个历史文件的小修改可能误报超 2 MiB,而且删除的净减少未计。建议与 #273 owner 先明确“新增净字节”还是“涉及文件总尺寸”;若确实是净新增,比较 base/head 对应 blob 的字节差并覆盖新增、修改、缩小/删除回归;若是保守总量预算,则改名和报告文案,避免误导。

[P2|HTTPS 前缀不能证明外置资产指针有效] 此处只校验 url.startswith("https://"),任何 HTTPS 网站/Release tag 浏览页都可通过;新增 test_validate_external_asset_manifest_valid 就以 .../releases/tag/v0.3.0(非具体下载资产)作为正例。这样无法落实 PR 描述的“GitHub Release asset with accessible URL”契约,不能证明 SHA 对应的字节可取得。建议先规定具体 Release asset 下载 URL 的可验证格式,明确 URL、大小、摘要和保留责任的验证深度;把 tag 页面/非资产链接作为负例,可访问性若未独立核验应报告未核实,而非视为已验证。

增量复核 1afe7515:仍有可复现的预算检查缺陷,请先修复以下 inline 项。
相对 上轮评审:显式无效 base 不再静默回退(本次 CLI 复现退出 1);小幅增长不再按整个文件累计,但删除/缩小仍未计入净额,路径解析又引入漏检。Release tag 页已被 URL 格式规则拒绝,但该规则只验证字符串格式,不能证明资产存在、可下载或与所填字节数/摘要一致;请据此限定声明,验证深度留给 owner 决定。
治理文档中的新阈值段落已撤回,PR 描述也改为候选;但 ci-ready.yml 仍会运行并以非零状态报告这些默认阈值。#273 的 R6、具体阈值和适用方式仍待 owner 决定,本评审不构成接受或新政策。文档另有一处无关的 baseline-vs-candidate → baseline-vs-campaign 变更,请检查是否意外。
验证范围:检查该 head 的代码、增量、测试和工作流;在临时 Git 仓库复现重命名、非 ASCII 路径和删除净额问题,并验证无效 base 的退出码。当前环境没有 pytest,未独立运行作者所列测试;也未访问或下载 Release 资产。当前 head 的 ready workflow 显示 action_required,尚无该 run 的 job 结果;不把作者测试声明当作 CI 通过。

[P1|重命名和 Git 引号路径可绕过预算] --raw 的 rename 有源和目标路径,这里只取源路径并 stat;在临时仓库将 600 KiB evidence/old.bin 重命名为 evidence/new.bin,Git 报 R100,源路径已不存在,检查器以 0 退出。移入 evidence/ 同样漏检。另加 evidence/é.bin 时 Git 输出带八进制转义的引号路径,这里的替换不能解码,文件也被记为 0。建议用 git diff --raw -z 正确解析源/目标路径,以目标文件判断单文件预算,并测试目录内/跨目录重命名及非 ASCII 路径。

[P2|仍不是 PR 级净新增] 对每个修改单独 max(0, …) 且删除计 0,会丢掉缩小/删除的负值。实测删 2,097,152 字节、加五个各 460,800 字节文件,检查器报 +2,304,000 并失败,但 evidence 树实际净增仅 206,848 字节。若采用描述中的净额语义,应按 base/head 的 evidence 范围累计有符号差额(包括删除、缩小和跨范围移动),需要非负展示时只在总计后处理,并补真实 Git 回归测试。最终统计口径仍须 owner 确认。

[P2|外部资产元数据类型错误被静默忽略] 当 external_assets 是对象或字符串而非列表时直接 continue,例如 {"bundles":{"x":{"external_assets":{"url":"https://example.invalid"}}}} 返回无错误,缺失的摘要、大小和责任人都未被报告。字段存在但类型错误应返回诊断;给非列表容器增加负例。URL 格式匹配也不验证远端可访问性或实际摘要,建议明确这是格式检查,避免声称已验证下载资产。

复核 2594a5ae:上轮主要路径及净额问题已有针对性修正,但仍有以下可复现的漏检/误报,请继续处理 inline。
相比 上轮评审,-z 路径解析覆盖了测试中的重命名及非 ASCII,删除负值纳入总额,外部资产容器类型不再静默忽略;文档误改已移除。新 Git 测试覆盖目录内重命名、移入、删除和非 ASCII,但并未实际构造移出场景。离线 URL 规则仍不证明真实可下载或摘要匹配。
本次对 13 个测试函数用轻量本地测试驱动逐一执行均通过(该环境无 pytest,故不是一次 pytest 运行);另在临时 Git 仓库复现下列缺陷,未进行远程资产访问。作者评论中的算术应为 5 × 450 KiB − 2 MiB = 206,848 字节,不是 152,848;测试断言本身使用正确表达式。
R6 阈值、适用范围和报告方式仍待 #273 owner 决定;本次评审不接受候选政策。当前 head 的 ready workflow 仍显示 action_required,未见 job 结果,不能视为 CI 通过。

[P1|路径改写和读取工作树仍可漏检或误报] POSIX 文件名中的反斜杠是合法字符,不是目录分隔符。实测 PR 新增 600 KiB 的 evidence/a\b,同时已有 1 字节的 evidence/a/b;这里替换路径后读取了后者,记录为 1 字节并放行。另一个实测:新增指向仓库内 600 KiB 文件的符号链接,Git 中链接 blob 仅 11 字节,stat 却跟随目标,误报 600 KiB。建议保留 Git 原始路径语义,并用 diff 的目标 blob 对象而非工作树跟随链接的大小,覆盖反斜杠路径和符号链接回归。

[P2|本地模式漏掉新目录中的未跟踪文件] 不带 --base 时 git status --porcelain -z 默认可能把未跟踪目录折叠成 ?? evidence/;此处仅接受 is_file(),所以新建的 evidence/new/large.bin 即使 600 KiB,返回记录仍为空并通过。可让 Git 展开未跟踪文件(例如 --untracked-files=all),并添加从干净仓库新建目录及超限文件的端到端负例。此项影响本地无 base 模式,不代表现有 CI base 模式同样受此问题影响。

[P2|必填字段的 JSON null 仍被接受] 上面的检查只判断 key 是否存在,而这里对 None 跳过类型校验。实测 external_assets 中对象的 url、sha256、bytes、retention_owner 四项全设为 null 时返回空错误列表,等同缺失所有有效元数据却通过。请对存在但为 null 的字段也执行类型/值检查,并分别或组合加入负例。

复核 e3b00f0e:上轮四个复现均已修正;另发现一个显式 base 模式的窄范围回归,见 inline。
已在临时 Git 仓库复测:反斜杠路径按正确 blob 大小计算,符号链接按链接 blob 而非目标计算,未跟踪目录中的大文件被展开,四个 null 字段均被拒绝。move-out 回归已加入。16 个测试函数由轻量本地驱动逐一执行通过;当前环境没有 pytest,这不是一次 pytest 运行。没有访问远程 Release 资产。
候选阈值、适用范围和报告方式仍待 #273 owner 决定,离线 URL 格式验证也不证明真实下载或摘要匹配。当前 head 的 ready workflow 为 action_required,没有 job 结果,不能视为 CI 通过。本评审不构成候选政策接受或正式批准。

[P2|合法空 blob 被误当成读取失败] get_git_object_size 对合法 0 字节 blob 和读取失败都返回 0,导致这里回退到工作树。实测:base 后提交空的 evidence/empty,随后只在工作树未提交地写入 600 KiB,再运行 --base <base>;HEAD 中 blob 是 0 字节,但记录为 614,400 字节并误报超限。此问题影响有未提交修改的显式 base 检查,干净 checkout 的 ready CI 不受这个具体场景影响。建议区分成功的零长度与对象读取失败,base diff 模式使用目标 blob 的真实大小,读取失败明确报错,并增加空 blob + dirty worktree 回归。

针对 1382ac5a 的增量复核:上轮空 blob / dirty worktree 问题已修复。
检查了相对 e3b00f0e 的代码及测试变更:base diff 不再以工作树大小替代合法 0 字节 blob;临时 Git 仓库中,HEAD 空 blob 加未提交的 600 KiB 工作树修改仍记录为 0,未产生误报。另验证不存在的 Git 对象会抛出错误,不再返回 0。新增回归测试覆盖该场景。
17 个测试函数由轻量本地驱动逐一执行通过;当前环境无 pytest,因此这不是一次 pytest 运行,也没有访问远程资产。本结论仅覆盖本次增量及上述复验,不是全范围批准。当前 head 的 ready workflow 为 action_required,尚无 job 结果,不能称为 CI 通过。#273 的 R6 阈值、适用范围和报告方式仍待 owner 决定;离线 URL 格式检查不证明资产可访问或摘要匹配。本评论不构成政策接受或正式 PR approval。
