Resolve 15 shared-control, overlay and responsive-layout issues plus the MCP editor being hidden behind settings. Restore theme contrast, danger and disabled states, visible keyboard focus, and consistent Continue fields. Keep the workbar add button reachable and model protocol values readable in narrow containers.
Make nested MCP and image dialogs usable above their parents with focus restoration, keep project Escape handling within the active modal, release native browser views for overlapping help, and restore keyboard access and Escape in sandboxed HTML previews without relaxing sandbox permissions. Add unit and real Electron regression coverage and update design and validation documentation.
Release note: 修复深浅主题下控件边框、危险操作、禁用状态和键盘焦点显示不一致的问题。MCP 编辑器与图片预览可在父弹窗上正常操作，HTML 全屏预览支持键盘进入和 Escape 返回；窄工作栏的添加按钮保持可用，模型连接协议文字完整可读。
Validation: the full suite recorded 5309 passed, 3 failed and 83 skipped. The ProjectSwitcher initial-focus regression was then fixed, and App, ProjectSwitcher and overlay Electron tests passed all 331 cases. The other two HeartbeatCenter failures were reproduced on isolated HEAD 11facf0 and remain pre-existing. Typecheck and lint passed after the fix; staged whitespace checks passed. The full suite was not rerun after the focused fix.
Limits: Electron evidence is from Windows development runs, with fixtures for unrelated services and native occlusion throttling disabled in some drivers. No production build, packaging, macOS/Linux, remote Agent host or external MCP connection validation; skipped tests and the documented scaling and native-select coverage gaps remain.
The tool environment page always displayed an unverified capability-dependency state even though it had no Skill or MCP evidence behind it. The page now shows only actual interpreter and companion-tool diagnostics; capability dependency status remains reserved for capability details with real validation results.
Release note: 工具执行环境页不再显示没有实际验证依据的能力依赖占位状态。
The custom Node.js and Python choices could appear unavailable until a candidate was already discovered, and selecting the source implicitly adopted the first candidate. The chooser now stays operable, waits for an explicit validated path, keeps cancellation quiet, and shows validation errors beside the affected runtime.
Candidate discovery now prioritizes active virtual environments and Conda before bounded user/system PATH and common Node/Python locations, while preserving canonical validation and deduplication.
Release note: 修复自定义 Node.js/Python 环境入口不可用的问题，并增加对 PATH、venv、Conda 和常见安装位置的解释器检测。
GoodBuddy can now provide managed Node.js and on-demand Python to local Skills and stdio MCP servers, or validate an explicitly selected custom interpreter. The Capabilities and tools settings page exposes source selection, diagnostics, installation progress, cancellation, and removal while new processes receive immutable PATH snapshots.
Application settings migrate to v10. Local terminal and remote Host environments remain unchanged. Windows x64 native-source Node and Python paths are validated; OSS mirror publication, redistributed license resources, and the remaining native platform probes are recorded as release blockers.
Release note: 新增工具执行环境，可为本机 Skills 和 stdio MCP 使用 GoodBuddy 托管的 Node.js、按需安装的 Python，或经过验证的自定义解释器。
The Skills catalog exposed nine product-marketing recipes as independent
capabilities and enabled every marketing package for every Runtime by default.
It now keeps five top-level Skills, loads the nine recipes on demand through
the product-marketing package, and leaves the three marketing Skills disabled
until users enable them. Existing saved Skill settings remain authoritative.
Release note: 内置 Skills 已从 14 个顶层入口精简为 5 个；去 AI 味和长文工具默认启用，产品营销类默认停用，已保存的用户设置保持不变。
Skills and MCP previously occupied separate top-level settings categories. They now share one Capabilities and tools category with accessible horizontal tabs, while the unimplemented tool environment remains hidden until its settings are usable.
Prevent nested PageTabs wrappers from collapsing to zero height in scrollable Flex layouts, add a CSS regression guard, and document the shared rule plus the planned local Node.js and Python environment.
Release note: 设置中心将 Skills 和 MCP 合并到“能力与工具”，并修复水平页签可能被压缩而不可见的问题；尚未实现的工具执行环境暂不显示。
Define repository and feature-scoped documentation rules for PRDs, User Stories, logic, UI, technical design, and progress evidence.
Move feature-owned documents under docs/features, add one entry point per feature, remove the redundant docs index, and update all affected cross-references. Expand the local tool environment design with explicit product, story, logic, UI, technical, and progress documents.
