profileSync stored avatar/banner paths with /api/uploads/ prefix on remote
instances, causing resolveAssetUrl to produce double-path URLs like
https://remote/api/uploads//api/uploads/file.jpg that 404'd. Store bare
filenames instead, strip prefix defensively in resolveAssetUrl and server-side
for existing data self-healing.
- SSRF protection: DNS resolution + private IP blocking on metadata fetcher
- Upload security: CSP/X-Frame-Options headers, SVG forced download, nosniff
- Auth hardening: JWT secret min length, password min 8 chars, token revocation via password_changed_at
- Attachment ownership verification before linking to messages
- Message length limit (4000 chars) enforced on client and server
- Asset URL validation on avatar/banner updates
- Federation instance validation (domain regex, origin scheme, length limits)
- DB indexes on all FK columns for query performance
- Migrations: nullable moderator columns, dm_messages reply_to FK constraint
- File cleanup on avatar/banner replacement and space deletion
- Fastify trustProxy, AbortController on fetches, typing map size cap
Profile and space layout changes on remote instances were being
overwritten by stale data on reconnect. Adds Last-Writer-Wins
timestamps so the client-relay mesh rejects stale writes:
- profile_updated_at column on users table with migration + backfill
- Server LWW guards on PATCH /users/@me and PUT /space-layout
- Bidirectional profileSync: pulls newer remote profiles to home
- LWW layout sync replaces home-authoritative _layoutFromTrueHome flag
- Layout pushes to ALL connected instances in parallel
Refactor RegisterPage into a two-step flow: credentials first, then
personalization (display name, avatar upload, avatar color). Replace the
dual-panel sliding layout with conditional rendering and CSS keyframe
animations to eliminate overflow-hidden clipping of focus rings.
Supporting changes:
- Server accepts avatarColor on registration
- Auth store resets all user-scoped stores on login/register/logout
- Voice store gains resetSession() for full session cleanup
- Sync presence status to federated instances
- Propagate presence_update to socialStore regardless of origin
