# Interactive Area Build CLI Design
## Scope
Add a zero-dependency terminal interface for choosing an area configuration and one or more existing
pipeline stages. It delegates execution to the existing `build-area.js` entry point and does not change
the pipeline's stage implementations or generated artifacts.
## Architecture
```text
npm run build
-> scripts/interactive-build.js
-> terminal menus (TTY only)
-> node scripts/build-area.js --config <area> --stages <canonical-list>
-> existing build pipeline
```
Extract the stage metadata, aliases, canonical execution order, and mutual-exclusion validation from
`build-area.js` into a CommonJS module under `scripts/lib/`. Both the interactive script and
`build-area.js` consume this module, making the menu's options the same source of truth as execution.
## Interaction
1. Discover and sort `config/areas/*.json`; present a single-select area menu.
2. Present a multi-select stage menu with descriptions and selection markers.
3. Arrow keys move focus, space toggles, enter confirms, and Ctrl-C/Escape cancels.
4. The menu prevents or reports the `intermediates`/`reimport` conflict before spawning a build.
5. The selected stages are normalized to canonical pipeline order and passed to `build-area.js`.
The interactive entry requires both stdin and stdout to be TTYs. Otherwise it exits non-zero with an
instruction to use `npm run build:area -- --config ... --stages ...`; it never falls back to defaults.
## Compatibility
- `build-area.js` remains the execution owner and keeps its CLI flags and defaults.
- `npm run build:area` continues to invoke it directly.
- `npm run build` changes only from the former default build alias to the interactive wrapper.
- A successful `cesium` selection continues to generate preview output through the existing behavior;
selecting `preview` explicitly remains valid for a standalone preview refresh.
## Validation
- Unit-test stage normalization, alias expansion, ordering, and mutual exclusion.
- Unit-test config discovery and non-TTY refusal without launching a build.
- Syntax-check both CLI entry scripts.
- Manually exercise the menu in a TTY: select an area, select unordered stages, confirm the canonical
command preview, and cancel before execution.
## Risks And Rollback
Raw terminal input must always restore raw mode and cursor state on confirmation, cancellation, and
errors. The wrapper only spawns the unchanged existing build script, so rollback is deleting the new
interactive entry and restoring the `build` package script.

# Interactive Area Build CLI Implementation Plan
1. Extract stage definitions, aliases, canonical ordering, and conflict validation from
`scripts/build-area.js` into a shared CommonJS module.
2. Update `build-area.js` to consume the shared resolver without changing non-interactive semantics.
3. Add `scripts/interactive-build.js` with TTY detection, area discovery, raw-mode selection menus,
cancellation handling, and child-process delegation to `build-area.js`.
4. Change `package.json` so `npm run build` calls the new interactive script while `build:area` remains
unchanged.
5. Add focused Node tests for stage planning and non-TTY behavior; do not invoke Blender, QGIS, or a
real area build in tests.
6. Run syntax checks, the focused tests, existing preflight/preview tests, and manually exercise the
interactive flow in a TTY.

# Interactive area build CLI
## Goal
提供一个交互式区域构建入口,减少手写 `npm run build:area -- --config ... --stages ...`
的频率用户可选择区域和一个或多个构建阶段CLI 按既有阶段约束执行。
## Confirmed Facts
- 当前 `scripts/build-area.js` 支持 `intermediates``reimport``blender``cesium`
`preview``compress` 六个阶段,并接受逗号分隔的 `--stages`
- `intermediates``reimport` 互斥:前者会从 OSM 重建 GeoPackage后者回导 QGIS 编辑。
- 执行顺序固定为 `intermediates/reimport -> blender -> cesium -> preview -> compress`
`cesium` 当前会自动写入 preview 产物。
- 项目没有终端交互依赖;现有命令行调用必须继续可用于脚本和自动化。
## Requirements
- R1提供交互式入口列出可用区域配置并允许用户选择目标区域。
- R2交互式入口允许一次选择多个阶段并清晰展示阶段名称与用途。
- R3选择互斥阶段时必须阻止执行并解释原因不得静默选择其中之一。
- R4执行多个阶段时必须使用既有依赖顺序而非用户勾选顺序。
- R5保留 `npm run build:area -- --config ... --stages ...` 的现有非交互行为与语义。
- R6无 TTY、取消输入或无效输入时必须安全退出不启动任何构建。
- R7TTY 交互使用方向键移动、空格多选、回车确认;菜单应显示当前选择状态。
- R8`npm run build` 启动交互式入口;`npm run build:area` 继续保留为非交互入口。
## Acceptance Criteria
- [ ] 用户可从终端选择区域和多项阶段,无需手写配置路径或逗号分隔阶段名。
- [ ] 选择 `intermediates``reimport`CLI 明确报互斥错误且不运行构建。
- [ ] 选择乱序的多个阶段时,实际执行顺序仍遵循既有管线顺序。
- [ ] 既有非交互 `build:area` 调用保持兼容。
- [ ] 取消或在非交互环境调用不会触发构建。
- [ ] 用户可用方向键、空格和回车完成区域及阶段选择。
- [ ] `npm run build` 启动交互菜单,`npm run build:area` 的现有调用保持不变。
## Key Decisions
- 采用终端原生多选菜单,而非输入逗号分隔编号;避免引入运行时依赖。
- `npm run build` 作为日常交互入口;`npm run build:area` 继续服务自动化和精确调用。
## Out Of Scope
- 修改各 stage 的构建业务逻辑、依赖关系或产物格式。
- 将巡航路线、QGIS 图层编辑或区域配置编辑纳入本次交互流程。
- GUI 或浏览器界面的构建控制台。
## Notes
- Keep `prd.md` focused on requirements, constraints, and acceptance criteria.
- Lightweight tasks can remain PRD-only.
- For complex tasks, add `design.md` for technical design and `implement.md` for execution planning before `task.py start`.
