feat(wechathook): 图片 CDN 上传打通 — 内部 API 发图完全可用 ✅ 

攻克图片发送最后一公里（LSPosed，微信 8.0.74，真机验证全分辨率送达）：

根因: b80.u.oj(o70.k) 只做「插消息 f9 + 插 ImgInfo b0 + 建缩略图」并
返回 List<o70.l> CDN 上传描述符，自己不提交 CDN。旧代码拿到 res 就丢掉
list → 上传永不触发（缩略图渲染但全图转圈）。真实编排 pe5.f.a 才循环
list 逐图提交（b80.s 只是 prebuild service checkPreBuildImg，不含 oj）。

补上第二步（照搬 pe5.f.a）: oj() 后对每个 o70.l:
  cdnSvc = n0.c(xs.d1.class)  // v70.w MsgImgFeatureService
  g = new r70.g(l.e, compress, c01.z1.r()/*self wxid*/, talker, k70.i0{a=3})
  cdnSvc.oj(g, l)             // → 启动 CDN 上传协程 e80.c

真机: oj() DONE res=size=1 + CDN submit DONE items=1，无异常；filehelper
收到消息点开是全分辨率原图（有原图+保存按钮，不再转圈）。

坑: v70.w.oj 内部走 ViewModelProvider.get 须主线程调（广播 receiver 本就在
主线程）；jadx 字段名末位字母=真实 dex 字段；XposedHelpers stub 无
getLongField 用原生反射。逆向靠拉 Tinker dex + jadx --single-class。

产物: WECHAT_SEND_API.md §3 完整两步实现 + API 表；backups 源码快照。

154   -### 剩余：图片 CDN 上传最后一公里
155   -- `b80.s` 只是 prebuild service（`checkPreBuildImg`），**不含 oj**；图片字节 CDN 上传是独立异步服务（log tag `MicroMsg.ImgUpload`）。我们同步 pj+oj 没把它拉起来 / 没跑完。
156   -- 试过 uri=null→fileUri、source 0→3，均未解决。imgId=0（真实是 MediaStore id）。
157   -- **下一步**：① hook `MicroMsg.ImgUpload` 上传 NetScene（像语音摸 `w21.g1` 那样）看真实发图怎么触发上传；② 或让流程跑在 worker 线程/协程（真实 prebuild 在 worker，我们是同步 main）；③ 或 imgId 用真实 MediaStore id（把文件插 MediaStore 拿 content://+id）。
  170 +**真机验证**（2026-07-07，微信 8.0.74）：`oj() DONE res=size=1` + `CDN submit DONE items=1`，
  171 +无异常；filehelper 收到消息，点开是**全分辨率原图**（有原图 + 保存按钮，不再转圈）。
  172 +
  173 +### 关键 API（逆向自 tinkerN.apk）
  174 +| 用途 | 反射 token / 签名 |
  175 +|---|---|
  176 +| 图片插件（插库+建描述符） | `b80.u.oj(o70.k) : ArrayList<o70.l>`（`n0.c(o70.e.class)`）|
  177 +| **CDN 提交（每图一次）** | `v70.w.oj(r70.g, o70.l) : flow.j`（`n0.c(xs.d1.class)`，tag `MicroMsg.ImgUpload.MsgImgFeatureService`）|
  178 +| CDN 参数 | `r70.g(String imgPath, int compressType, String fromUser, String toUser, k70.i0 crossParams)` |
  179 +| crossParams | `k70.i0()` 无参构造，字段 `a`=source(int，普通图=3) |
  180 +| 自己 wxid | `c01.z1.r() : String`（静态）|
  181 +
  182 +**坑**：`v70.w.oj` 内部走 `ViewModelProvider.get(e80.f.class)`，**必须主线程**调（广播 receiver 本来就在主线程，OK）；用的是服务自己的 ViewModelStore，不需要活的 Activity。真实 CDN 上传在服务的协程 scope 异步跑，`oj` 立刻返回一个 flow，不用 collect 也会传完。orchestrator 是 `pe5.f.a(...)`（`b80.s` 只是 prebuild service `checkPreBuildImg`，不含 oj）。
