BUILD.md documents 2 flavors (global, cn) but android/app/build.gradle.kts defines 6

[chirag127]

Problem

BUILD.md lists only global and cn flavors, but the actual Android build defines 6, and AGENTS.md tells contributors to avoid global/cn for local dev.

Steps

1. Follow BUILD.md: flutter run --flavor global
2. Read AGENTS.md line 15-20 which says # Stable overseas; avoid for local dev and instructs flutter run --flavor globalDev
3. Read android/app/build.gradle.kts lines 92-137

Expected

BUILD.md documents all 6 flavors and matches AGENTS.md guidance on which to use for local dev.

Actual

android/app/build.gradle.kts:92-137 defines 6 productFlavors: global, cn, globalEarly, cnEarly, globalDev, cnDev. BUILD.md's table only covers global and cn. New contributors miss the recommended *Dev flavors that use isolated package/data.

Environment

• Repo main at 2026-07-04, pubspec.yaml version 1.0.36+120
• Flutter SDK >=3.6.0 <4.0.0 (pubspec.yaml:7)
• File: BUILD.md lines 5-9 (flavor table)
• File: android/app/build.gradle.kts lines 92-137 (productFlavors)
• File: AGENTS.md lines 13-19 (flavor globalDev/cnDev/globalEarly/cnEarly documented, global/cn marked avoid for local dev)
