+- [ ] Upgrade over a build with an existing server. Launch Gotcha once, then
+      add both **Recent Activity** and **Open Pull Requests** from the system
+      widget gallery; the saved server and Keychain token work without re-entry.
+- [ ] Both widgets are offered only in the large system size and use native
+      widget margins, typography, tint, relative update time, and light/dark
+      appearances without clipping at the largest accessibility text size.
+- [ ] Recent Activity shows up to six latest activity rows for its configured
+      server. Open Pull Requests shows up to five open pull requests. Loading,
+      empty, missing-server, and API-error states remain legible and do not
+      expose account data while the device is locked.
+- [ ] Add a second server profile, long-press each widget, choose **Edit
+      Widget**, and assign a different server to each. The displayed server
+      name and rows update independently; deleting a selected server changes
+      that widget to its missing-server state instead of showing another
+      server's data.
+- [ ] Tap Recent Activity; Gotcha opens or foregrounds at the Home root. Tap
+      Open Pull Requests; Gotcha opens or foregrounds at the PR root. Both
+      routes discard a stale detail stack in the destination tab.
+- [ ] Add, edit, select, and delete server profiles in Gotcha, then return to
+      the Home Screen. Widget configuration choices and timelines refresh to
+      match the persisted server list.
