Server:
- Extract image width/height on upload via image.DecodeConfig (header-only)
- Add width/height columns to attachments table (migration 007)
- Include dimensions in AttachmentInfo JSON (optional, backward-compatible)
Client:
- Reserve exact space for images using server-provided dimensions
- Fallback min-height: 200px for external/old images, cleared on load
- Remove premeasureAll() — was caching wrong heights for unloaded images
- Smart per-type height estimates: 32px dividers, 42/72px text, +220px
per image attachment, +320px for YouTube embeds
- Batch ResizeObserver corrections to single RAF with anchor-based scroll
preservation (topmost visible item stays in place)
- Fenwick tree for O(log n) offset lookups (replaces O(n) linear scans)
- CSS contain: layout style on .msg-image to isolate layout shift
- Fix double-close panic in Hub.Stop/GracefulStop using sync.Once (#3)
- Bump golangci-lint action to v9 with v2.11.3 for Go 1.25 support (#4)
- Add input validation guards to SearchMessages (#5)
- Handle promise rejections in InviteManager with error toasts (#6)
- Add missing reply_to and edited_at columns to admin test schema (#7)
- Add ClientCount to HubBroadcaster interface and wire into stats endpoint (#8)
Server:
- Add message search and pinned messages support
- Add admin hub integration and live connection stats
- Update admin test mocks for hub interface
Client:
- Add data-testid attributes to components for E2E testing
- Add window management capabilities (position, size, maximize)
- Add prod E2E test config and script
- Fix CSS imports (use vite bundling instead of HTML link tags)
- Add inline styles to InviteManager overlay for reliability
- Update CHATSERVER.md references from WPF to Tauri
Docs:
- Update quick-start guide
- Add MessageAPIResponse, UserPublic, AttachmentInfo, ReactionInfo types
- Add GetMessagesForAPI query with user object, reactions (with me flag),
and attachments array matching API.md shape
- Update SearchMessages to return user object {id, username, avatar}
instead of flat username field
- Update GET /messages handler to use new API-shaped query
- Batch-fetch reactions for all messages in a single query for performance
Root cause: server's db.Role and db.VoiceState structs had no JSON tags,
causing Go to serialize field names as PascalCase while the C# client
expected snake_case. Every role deserialized with Id=0, crashing
ToDictionary with "duplicate key: 0".
- Add json tags to Role and VoiceState in Server/db/models.go
- Change Disconnected event to carry reason string for diagnostics
- Wire ErrorReceived in MainViewModel to show server-side WS errors
- Fix MainWindow to surface WebSocket errors on MainPage (not ConnectPage)
- Use _reconnectCts.Token for receive loop instead of caller's token
- Make ToDictionary calls safe with TryAdd to prevent future crashes
