Version：5.4.6
Opportunity：2026-06-10-dext-receipt-tracker

## 摘要

- 包类型：xapk，inner APK 数：4
- 引擎 / 框架：native
- SDK 线索：firebase
- Endpoint candidates：9
- 结论口径：本报告只基于静态 ZIP / Manifest / 字符串证据；不代表真实运行路径已验证。

## 直接证据

- [high] Manifest package id is com.receiptbank.android（source: `AndroidManifest.xml`，status: `verified`）
- [high] Manifest declares 26 permissions（source: `AndroidManifest.xml`，status: `verified`）
- [high] Engine/framework markers: native（source: `APK file inventory`，status: `verified`）
- [high] Static strings include 9 endpoint candidates（source: `Text/string scan`，status: `verified`）
- [high] Package contains 4 native libraries（source: `APK file inventory`，status: `verified`）

## 推断

- [medium] SDK markers suggest: firebase（source: `Manifest, filenames, and text strings`，status: `inferred`）

## Warnings

- apktool manifest decode skipped 3 split APK(s)
- binary AndroidManifest.xml decoded with apktool

## 下一步

- 真机/模拟器验证 onboarding、paywall、首个可感知价值和崩溃路径。
- 把 endpoint candidates 与 HAR / MITM / Frida 动态证据对齐，避免只凭静态字符串下结论。
- 多版本对比权限、SDK、endpoint、native libs 和资源路径变化。
