What's Wrong?

Hovering over a message in the conversation view no longer reveals the per-message hover toolbar in the desktop app. Both the "Revert to here" (rewind) control and the message timestamp are affected - the entire hover row fails to render.

This is different from the known "rewind is rejected" reports (#57206): here the control never appears at all, so there is nothing to click.

The toolbar used to render on this machine. It stopped appearing around the update to app version 1.26832.0.0 (2026-08-07), and updating to 1.30096.1.0 and then 1.30096.5.0 (2026-08-15) did not restore it.

What Should Happen?

Hovering over a message should reveal the per-message hover toolbar containing the "Revert to here" (rewind) control and the message timestamp, as it did before.

Error Messages/Logs

No error is shown in the UI when the toolbar fails to render.

Version history on this machine, from %APPDATA%\Claude\logs\main.log:
  2026-08-05 .. 08-07 : 1.25927.0.0   (toolbar working)
  2026-08-07 .. 08-15 : 1.26832.0.0   (toolbar stopped appearing)
  2026-08-15          : 1.30096.1.0 -> 1.30096.5.0  (still not appearing)

Possibly related entry from 2026-08-09 (may or may not be connected):
  [error] Failed to save session <id>: Private dir leaf redirects
  (junction/substitute-name plant): %APPDATA%\Claude\claude-code-sessions\<account>\<id>
  { name: 'PlantDetectedError' }

Steps to Reproduce

  1. Open the Claude desktop app on Windows
  2. Create a brand-new session (so no migrated/synced session data is involved)
  3. Send any message
  4. Move the mouse over the message bubble and wait

Expected: hover toolbar appears (Revert to here / timestamp)
Actual: nothing appears; no hover row is rendered

Additional Information

Things ruled out before filing:

  • Setting disabled: showMessageTimestamps: true is set - no effect
  • Checkpointing off: fileCheckpointingEnabled: true explicitly set - no effect
  • UI zoom: reset with Ctrl+0 - no effect
  • Window too narrow: window maximized - no effect
  • Transient render glitch: app restarted many times over several days - persists
  • Session data / migration: reproduces in a brand-new session
  • Enterprise policy: no managed-settings.json; no Policies\ClaudeCode registry keys
  • Popout / tiled window: reproduces in the main window as well

Additional observation: no checkpoint store exists on disk (~/.claude/checkpoints and %APPDATA%\Claude\checkpoints are both absent), although sessions have been in use for weeks.

Note: ~/.claude on this machine is a directory junction to a OneDrive-synced folder. This was investigated as a possible cause; the issue reproduces regardless, but it is mentioned in case junction detection interacts with checkpoint storage.
