Operations: Troubleshooting (rebuilt on the v5 Admin Guide's Section 9 model), plus AI-Assisted Troubleshooting teaser and Log Message Reference placeholder Troubleshooting: symptom -> likely cause -> remedy, organized by area (startup, cluster/orchestration, connection, source data, client data, load) after the old Enterprise Server Admin Guide's Problem-Diagnosis section, with obsolete v5 content (RMDS/DACS/NYSET, load-balancer/UDP cluster, jconsole) dropped and each item grounded in verified v6 REST/log calls. Adds a standard diagnostic procedure with capture-before-restart. AI-Assisted Troubleshooting: preview teaser (own nav entry) - the support assistant that pulls fabric dumps, correlates logs, and runs live probes. Log Message Reference: structured per-component placeholder for the WARNING/SEVERE catalog, to be populated over time. Sidebar: add both new pages.
