# 2026-04-18 — Document delete permissions + three-dots menu fix

**Timestamp:** 2026-04-18T00:00:00Z

## Summary

Added a proper permission model for document deletion: owners and admins can always delete; group members can delete only when the share was explicitly granted `can_delete=true`. Fixed silent delete failures (watch docs returning 404 with no user feedback) and fixed the three-dots context menu being clipped by `overflow-hidden` on the table container.
