Chengfang Lu e72bc061c5 feat: HSAP platform v2 — modular navigation, quality review, audit log, world model simulation

Major changes:
- New frontend (platform/web/): Vite + React 18 + TypeScript + Tailwind
- 4-module navigation: 数据送标 / 模型管理 / 车队管理 / 系统管理
- Data catalog with charts (DMS/ADAS/Lane 3-tab view)
- Quality review workflow (标注质检): Good/Fine/Bad scoring with auto-advance
- Audit enhancements: batch operations, rejection categories, Feishu notifications
- Operation audit log (操作日志)
- World model simulation studio (仿真工坊)
- Dataset version management with snapshots and diff
- ADAS 7-class dataset integration (138K images organized + compressed)
- User management with Feishu integration and pagination
- CRUD/search/filter on all pages, card layout redesign
- PIL-optimized image overlay rendering
- Auto-snapshot on build, in_review workflow stage
- Removed embedded algorithm code (now in workspace)

merge2

Merge multiple streams into one stream in sequence or parallel.

Install

Install with npm

npm install merge2

Usage

const gulp = require('gulp')
const merge2 = require('merge2')
const concat = require('gulp-concat')
const minifyHtml = require('gulp-minify-html')
const ngtemplate = require('gulp-ngtemplate')

gulp.task('app-js', function () {
  return merge2(
      gulp.src('static/src/tpl/*.html')
        .pipe(minifyHtml({empty: true}))
        .pipe(ngtemplate({
          module: 'genTemplates',
          standalone: true
        })
      ), gulp.src([
        'static/src/js/app.js',
        'static/src/js/locale_zh-cn.js',
        'static/src/js/router.js',
        'static/src/js/tools.js',
        'static/src/js/services.js',
        'static/src/js/filters.js',
        'static/src/js/directives.js',
        'static/src/js/controllers.js'
      ])
    )
    .pipe(concat('app.js'))
    .pipe(gulp.dest('static/dist/js/'))
})

const stream = merge2([stream1, stream2], stream3, {end: false})
//...
stream.add(stream4, stream5)
//..
stream.end()

// equal to merge2([stream1, stream2], stream3)
const stream = merge2()
stream.add([stream1, stream2])
stream.add(stream3)

// merge order:
//   1. merge `stream1`;
//   2. merge `stream2` and `stream3` in parallel after `stream1` merged;
//   3. merge 'stream4' after `stream2` and `stream3` merged;
const stream = merge2(stream1, [stream2, stream3], stream4)

// merge order:
//   1. merge `stream5` and `stream6` in parallel after `stream4` merged;
//   2. merge 'stream7' after `stream5` and `stream6` merged;
stream.add([stream5, stream6], stream7)

// nest merge
// equal to merge2(stream1, stream2, stream6, stream3, [stream4, stream5]);
const streamA = merge2(stream1, stream2)
const streamB = merge2(stream3, [stream4, stream5])
const stream = merge2(streamA, streamB)
streamA.add(stream6)

API

const merge2 = require('merge2')

merge2()

merge2(options)

merge2(stream1, stream2, ..., streamN)

merge2(stream1, stream2, ..., streamN, options)

merge2(stream1, [stream2, stream3, ...], streamN, options)

return a duplex stream (mergedStream). streams in array will be merged in parallel.

mergedStream.add(stream)

mergedStream.add(stream1, [stream2, stream3, ...], ...)

return the mergedStream.

mergedStream.on('queueDrain', function() {})

It will emit 'queueDrain' when all streams merged. If you set end === false in options, this event give you a notice that should add more streams to merge or end the mergedStream.

stream

option Type: Readable or Duplex or Transform stream.

options

option Type: Object.

end - Boolean - if end === false then mergedStream will not be auto ended, you should end by yourself. Default: undefined
pipeError - Boolean - if pipeError === true then mergedStream will emit error event from source streams. Default: undefined
objectMode - Boolean . Default: true

objectMode and other options(highWaterMark, defaultEncoding ...) is same as Node.js Stream.
