- Add /trading and /admin named Socket.IO namespaces; root namespace kept for backward compat; admin namespace rejects non-admins at connect time - Wire auditRepository.ts: persist TradeAuditEvent to Cosmos audit-events container (best-effort); expose GET /api/admin/audit for admin queries - Add tradingTelemetry singleton (Node.js Map-based storage adapter); init and fatal-error tracking wired in index.ts main() - Add TAB_MARKETPLACE_ENABLED / TAB_MEMBERSHIP_ENABLED config flags; expose tabs.* shape in GET /api/feature-flags response - Fix SupabaseService URL validation (regex check before createClient) - Wire check:api-contract and check:audit-repository into npm run test - Switch @bytelyst/* deps to file:../vendor/* references Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
