 - 云端同步完成：本地改动已提交为 `83cc859 Productize jyotish app release surface` 并推送到远端 `codex/release-hygiene-ci`；GitHub API 确认现有 PR #6 处于 open，head 已更新到 `83cc859`。
 - 修复 PR CI 云端稳定性风险：`.github/workflows/ci.yml` 将质量门命令从默认 browser profile 改为 `python scripts/run_quality_gate.py --profile quick --skip-yoga-logic`，避免 GitHub Actions 在未安装 Playwright/真实浏览器依赖时误跑 browser click smoke；完整 browser/release profile 仍作为发布前本地/手动守门。
 - 验证完成：`python3 -B -m pytest tests/test_frontend_productization.py::test_quality_gate_declares_fast_browser_release_profiles tests/test_frontend_productization.py::test_release_quality_gate_tracks_untracked_product_files -q` 通过；`.github/workflows/*.yml` 均可被 PyYAML 解析。
+- GitHub Actions 复查发现 PR #6 head `062dc86` 的 `validate` 与 `test` 均失败：`validate` 失败点为 Ruff lint，`test` 失败点为全量 `python -m pytest -q`；Actions 日志下载需要仓库 admin 权限，改为本地补齐 dev 依赖后复现。
+- 修复 CI 阻断：`tests/conftest.py` 统一保证当前仓库 `scripts` 在 `sys.path[0]`，并在每个测试前清理从 `~/.workbuddy/skills/jyotish-vedic-astrology/scripts` 载入的同名模块，避免历史测试收集期污染 `prashna`；`tests/test_ashtakavarga_invariants.py` 给需要先改 `sys.path` 的脚本导入加 Ruff E402 标注。
+- 验证完成：`python3 -m ruff check scripts/run_quality_gate.py tests/test_varga_bphs.py tests/test_ashtakavarga_invariants.py tests/test_cli_smoke.py tests/test_yoga_rules_integrity.py` 通过；`python3 -m pytest -q` 全量通过；`python3 scripts/run_quality_gate.py --profile quick --skip-yoga-logic` 通过，核心质量门 198 个 pytest、npm build 与 runtime smoke 通过。

 - [x] 发布/仓库卫生第一步：release profile 新增关键产品文件未跟踪守门，28 个产品关键 untracked 文件已纳入 Git 暂存，`audit_fragments.py --strict` 当前报告 untracked_count=0。
 - [x] 完整 browser/release profile 与云端分支同步检查：browser/release profile 均通过，分支 `codex/release-hygiene-ci` 已推送到远端并更新现有 PR #6。
 - [x] PR CI 云端稳定性修复：`.github/workflows/ci.yml` 显式使用 `--profile quick --skip-yoga-logic`，避免 PR 环境因未安装真实浏览器/Playwright 依赖而误触 browser click smoke。
-- [ ] 下一步：检查 GitHub Actions 运行结果与发布包链路，必要时补充 release-only workflow 的 browser/release 守门。
+- [x] GitHub Actions 失败根因修复：本地复现 PR `validate` 的 Ruff E402 与 `test` 全量 pytest 的 WorkBuddy 旧 skill 路径污染，新增 pytest import guard 并修复 Ashtakavarga lint。
+- [ ] 下一步：推送 CI 修复后复查 GitHub Actions 结果；继续检查发布包链路，必要时补充 release-only workflow 的 browser/release 守门。
