 - **处理（现行口径）**：断言默认渠道、默认目标等环境派生值的测试，必须用现有 `withEnv` 显式清除相关变量；构建入口继续按 `AGC_UPDATE_CHANNEL` 选择渠道，不为迁就测试改生产逻辑。

+- **复发（2026-09-30）**：`80bf54c3` 新增的 NSIS 改名钩子用例（`release stages Node before Tauri and injects its resource mapping only for bundles`）又直接读环境渠道、却无条件断言 dev 专属钩子，release 渠道的 macOS Job 再次在 Tauri 构建前失败（`Cannot read properties of undefined (reading 'nsis')`，2026-09-30 04:00 那次构建在 Checkout 后约 2 分钟即死、零产物），`release-mac` 因此停在旧版本；同一批门禁的其它用例与 dev 渠道都不受影响。按同一口径把该用例的 `resolveReleaseContext` 渠道读取裹进 `withEnv({ AGC_UPDATE_CHANNEL: undefined })` 后，`AGC_UPDATE_CHANNEL=release`、`=dev`、未设置三态均 44/44 通过。新写依赖渠道或目标的用例必须走 `withEnv`，不能依赖 `AGC_UPDATE_CHANNEL` / `AGC_BUILD_TARGET` 的默认值。
