…modular contract compilation Core Web Vitals tracking (LCP, FID, CLS) with budget enforcement and regression alerts. Performance budgets validated in CI via performance-ci.yml workflow. Real user monitoring (RUM) session snapshots with 30s periodic flush to configurable endpoint. Performance regression alerts forwarded to Sentry breadcrumbs in production. Route transition tracking wired into NavigationContainer.onStateChange. Bundle size impact analysis via trackBundleSize() in performanceMonitor. Render/interaction/memory/route/bundle metrics with p95 aggregation and summary. PerformanceDashboardScreen redesigned with Core Web Vitals panel, regression alerts, and route transitions. usePerformanceProfiler extended with LCP option and new useFIDTracker hook. performance-budget.json extended with routeTransitionMs, lcpMs, fidMs, clsFrameDrops, bundleSizeBytes. check-performance-budget.js updated to validate all new budget fields. Gas benchmark tests added in contracts/subscription/src/gas_benchmarks.rs. gas-benchmark.sh updated to target new benchmark test functions. GAS_OPTIMIZATION.md documents storage slot packing, lazy init, and before/after comparison. contracts:gas-benchmark and contracts:gas-benchmark:baseline npm scripts added. WebSocket connection pooling via socketPool map (shared socket per URL, ref-counted). Message batching with configurable flush interval and head-drop backpressure. Heartbeat ping/pong health monitoring with auto-reconnect on pong timeout. Exponential backoff with jitter (capped at 30s) for reconnection. Per-client send queue on server with slow-consumer overflow protection. Per-user connection limit (default 5) for graceful degradation. WebSocketMetrics: throughputEps, eventsDelivered/Dropped, batchesFlushed, evictedClients. websocketStore.ts Zustand store exposes state, metrics, connect, disconnect, subscribe. docs/websocket-optimization.md documents all features and transport integration. Modular contract compilation: all 13 crates now use workspace soroban-sdk dependency. Feature flags per crate: testutils, oracle, extended, metering, audit-log, credit, fraud, full. contracts/.cargo/config.toml sets wasm32-unknown-unknown as default build target. contracts/Makefile with build-core, build-full, build-minimal, size-report, bench-compile targets. build-contracts action rewritten with per-crate targeting and binary size step summary. contract-build.yml CI: feature matrix (8-way parallel), binary size monitoring on PRs, compile benchmark.
