• Session Management: Secure session handling with automatic expiration

Impact: Does not affect functionality Affected Components:

• Media viewer thumbnail strip
• Notifications panel
• Profile card
• Quick recall panel
• Recording player/editor
• Workspace members list

Resolution: Will be fixed in v0.9.2 with proper ARIA attributes and keyboard handlers.

Reason: API mismatch or Jest memory issues Impact: Core features are still tested and working Examples:

• use-search-suggestions.test.ts (memory crash)
• use-bot-commands.test.ts (API mismatch)
• use-channel-permissions.test.ts (API mismatch)

Resolution: Tests will be rewritten to match actual API in future sprints.

Impact: Unknown device-specific bugs Platforms:

• iOS builds configured but not tested on physical devices
• Android builds configured but not tested on physical devices

Resolution: Device testing will be completed before v1.0.0 release.

Impact: Video uploads accepted but not transcoded Current State:

• Image processing fully working (Sharp.js)
• Video files accepted and stored
• Transcoding/optimization not implemented

Resolution: FFmpeg integration planned (16-24 hours of work).

None identified. All core features are working and tested.
