 ## Current Test
 <!-- OVERWRITE each test - shows where we are -->
 
-[testing complete]
+number: R1
+name: Username Visible in Account Settings
+expected: |
+  Open Account / Settings page. The "Account information" section should now show a
+  "Username:" row displaying your handle prefixed with @ (e.g. @alice).
+awaiting: user response
+
+## Re-test Pass (2026-06-01)
+
+### R1. Username Visible in Account Settings
+expected: Open Account / Settings page. The "Account information" section should now show a "Username:" row displaying your handle prefixed with @ (e.g. @alice).
+result: issue
+reported: "Handle shows with @ prefix in Account settings but the share input requires the handle WITHOUT @. The @ display creates confusion — user must type without it."
+severity: minor
+
+### R2. Shared Badge Display (re-test)
+expected: Share a document with another user (now that handles are visible). The shared document's card should show a "Shared" pill/badge. Documents not shared show no badge.
+result: pass
+
+### R2b. Shared Document Accessible to Recipient
+expected: In the recipient's "Shared with me" folder, clicking a shared document should open it normally.
+result: pass
+
+### R2c. Share Dialog Layout
+expected: In the Share dialog, the Share button should be inside / aligned with the recipient input area, not overflowing outside it.
+result: pass
+
+### R3. Update Share Permission Toggle (re-test)
+expected: Open the Share dialog for a document that is already shared. Each recipient row should have a View/Edit toggle. Clicking the toggle changes the permission — reflected immediately.
+result: pass
+
+### R4. Audit Log @ Prefix (re-test)
+expected: Open Admin → Audit Log tab. User handle entries should now display with @ prefix (e.g. @alice instead of alice). Both the "user" and "actor" columns should show the @ prefix.
+result: issue
+reported: "There is only a user column and no actor column. I want a user and email column, not an actor column, and I do NOT want the @ prefix on the username."
+severity: major
+
+### R5. CSV Export — Filter Indicator (re-test)
+expected: In the Audit Log tab, apply a filter (e.g. type a user handle and click Apply). Then look at the Export CSV button — it should now show "N filter(s) active" in amber text below it. Also, a "Clear filters" button should appear next to "Apply filters". Click Clear filters to reset and confirm the amber indicator disappears.
+result: pass
+
+### R6. Cloud Folder Error Guidance (re-test)
+expected: Navigate to a cloud storage folder (e.g. /cloud/onedrive/root) without a connected cloud provider. Instead of the generic "Failed to load folder contents" error, you should now see: "No cloud provider connected. Go to Settings to connect a cloud storage account." with a "Go to Settings" link.
+result: skipped
+reason: No cloud storage folders visible in the sidebar — no disconnected provider entry point available to trigger the error state.
