 原 candidate verifier 对这个继续开发分支的 review 包仍 **exit 1 / Candidate provenance or manifest is invalid**，未创建提取目标；不修改 manifest 绕过 main-only admission，红预算也是独立阻断。这是父候选字节完整性证据，不是发布准入、生产或新源码 CI。

+
+证据：[m3-source-map-security-20261011.json](performance-evidence/m3-source-map-security-20261011.json)。按升级方案第 12 节隔离到 `codex/v16.0.0-source-map-js-security`，基点 411f49d，PR 目标仅为继续开发分支，不是 main。
+
+实际仅更新 package-lock.json 中 `source-map-js` 的 version / resolved / integrity 三字段：**1.2.1 → 1.2.2**。109 个锁文件 entry 的 inventory 和其他全部 entry 不变；满足现有 PostCSS `^1.2.1`，无需升 Vite/PostCSS、添加 overrides 或修改 package.json。原 5 项安装脚本 allowlist 不变；官方 npm 冻结 `ci --ignore-scripts`、再次 policy 核验，仅执行既有 esbuild installer。
+
+[官方 GHSA](https://github.com/advisories/GHSA-68fv-2mgg-jv7q) / [上游修复 PR](https://github.com/7rulnik/source-map-js/pull/79) 指向恶意 indexed source map 的同步资源耗尽；修复版本为 1.2.2。实际链均为 dev：Vite 8.2.2 → PostCSS 8.5.26 → source-map-js。未发现持仓、行情或 OCR 图片输入到该解析器的生产路径，build-site CSS 直接复制、OCR esbuild sourcemap:false；但不以生产 omit-dev 0 为由豁免全量审计。
+
+补丁后全量 **892 tests / 889 pass / 0 fail / 3 Windows 条件 skip**，syntax **192**，官方 audit **0 vulnerabilities / exit 0**；桌面合成 E2E **23/23（54.4 秒）**，自有 12437 服务退出。3 个绝对 readiness 样本完整保留，不形成 paired latency 结论。E2E 后两次同父 411 epoch **1791689435** build，关键发布集均为上述 **fc15bbea...**，与补丁前同 epoch 完全一致；app/OCR bytes/SHA 全核验通过，未执行 OCR。原 5 个运行源码绑定 hash 未变；不声称未来 patch SHA / Linux raw 指纹或整个 site inventory 与该本地值相同。
+
+实际预算仍 cold **42,944 PASS**、all **81,195 FAIL / exit 1**；补丁没有以依赖升级改善或隐藏包体积。回滚点为 411f49d，若需回滚只 revert 独立补丁提交；回退会重新引入已知漏洞，不能成为可发布状态。当前安全 PR 尚待精确提交 CI / 集成；M3 仍未退出，不进入 M4，不 merge main / deploy / bump。
+
+独立实际 API 有界探针 **exit 0**（64 MiB child heap、5 秒 timeout，实际 9.922 ms）：合法双 section 查询/遍历/flatten/basic roundtrip/SourceNode、4 层 2 叶、小 gap 与短 code 路径通过；21 个非法/越界/累计越界/乱序场景拒绝，非法和单上限在读取 map getter 前拒绝。首次使用 `SourceMapGenerator.fromSourceMap(indexed consumer)` 因 undefined sourceRoot 出现 TypeError；上游 tag diff 证实该便捷方法/constructor 未改，是原有限制，不混同补丁回归。没有执行旧版本资源耗尽 payload；此探针未新增永久项目测试。
