v0.6.0

What's New

Bulk Unshare: Retry, Verification & Neo4j Cleanup

• Retry logic — Automatic retry on Graph API 429 (throttling) with Retry-After support and 5xx exponential backoff (max 4 retries)
• Post-delete verification — Re-fetches permissions after deletion to confirm they were actually removed
• Neo4j cleanup — Removes SHARED_WITH relationships on verified success so files disappear on page refresh
• Inter-file throttle delay — 0.5s delay between files to avoid triggering rate limits

Structured Error Reasons & Result Dialog

• 5 error categories — ACCESS_DENIED, NOT_FOUND, THROTTLED, VERIFICATION_FAILED, UNKNOWN — each with a user-facing message and suggested action
• Result dialog — Replaces the auto-hiding toast with a persistent dialog showing per-file outcomes:
  • Color-coded reason chips (red for Access Denied, orange for Rate Limited, blue for Not Found)
  • File paths resolved from cache
  • Suggested actions for each failure
  • "Retry Failed" button for throttled files
