Problem

When workspace provisioning fails during task creation, the failure is not evident from the Tasks UI. Users see a task that appears to be in progress or stuck, but cannot easily determine that the underlying workspace build has failed.

This creates a poor user experience where:

• Users wait indefinitely for tasks that will never complete
• No clear indication of what went wrong
• Users must navigate away from the task UI to debug issues

Current Behavior

• Task UI shows indeterminate progress
• No indication of provisioning failure
• No link to workspace or build logs
• Users cannot troubleshoot directly from task interface

Expected Behavior

• Clear error state when provisioning fails
• Direct link to failed workspace build
• Access to build logs from task UI
• Clear messaging about what failed and next steps

Proposed Solution

Extend the task UI to:

1. Display clear error states for failed provisioning
2. Show link to associated workspace when available
3. Provide access to workspace build logs inline or via link
4. Show helpful error messages and recovery options

Related Work

• tasks: ui: show build logs and agent logs in task UI when workspace build is in progress #19363 (closed) - showed build logs during task creation
• feat: show workspace build logs during tasks creation #19413 (merged) - added workspace build logs during creation

This builds on that work but focuses on failure cases and error visibility.
