Database: - Add missing indexes (users.credits, users_currency(type,amount), users_settings.respects_received, camera_web.timestamp, messenger_offline.user_id) via migrations 0020/0021 - Use partial .select() everywhere instead of SELECT * (tickets, users, rooms, audit logs, catalog tree, polls, radio, password reset) - Add queryPrepared/queryPreparedOne (server-side prepared statements) and switch the login check to a prepared statement; drop dead cache options from the pool config - Raise total_users/total_rooms COUNT(*) cache TTL to 5m Caching: - Consolidate the three cache helpers (cached, redisCache, cachedQuery) into a single memory-first implementation backed by Redis - invalidateKey now clears the in-process cache as well as Redis - Cache homepage sections, news list, and leaderboard tabs; share one news_list cache key between homepage and news archive - siteSettings: in-process cache with TTL so repeated getters no longer pay a Redis round-trip per call - Share a 10s poll cache across all radio SSE connections - Normalize timestamps after cache reads (Redis JSON round-trip) Assets: - Enable AVIF/WebP via images.formats and remove unoptimized from news covers and the homepage hero (149KB jpg) with proper sizes/priority - Support ?format=webp|avif|png in the /imaging proxy via sharp Other: - Fix pnpm supply-chain minimumReleaseAge failures by excluding the freshly-published packages (next 16.3.1, hookform resolvers 5.8.0, resend 6.20.0) - Remove unused before/after fields from housekeeping AuditEntry
