PARTIAL SAVE: writes ONLY the 'Analytics' field of TitlePublicConfigurationModel; all other v1/v2 fields stay untouched. Custom events - Firebase Analytics parity. The game sends its own events (logEvent(name, params, value)); the engine stores them per player per UTC day and the dashboard reports counts, unique players, value sums and breakdowns by platform, app version, OS, device, language, country, new/returning and acquisition source; A/B experiment goals and custom funnel steps can use these events. Enabled is the master switch and defaults to OFF. EventNaming: "Open" (any valid name is accepted and joins the title's event catalog up to the PLAN limit) or "Declared" (only names listed in Events). Events maps an event name (^[A-Za-z][A-Za-z0-9_]{0,39}$; prefixes idos_/firebase_/google_/ga_ are reserved, except the automatic idos_* events) to a display name, description and a Blocked flag. Dimensions registers event parameters as reporting dimensions (like GA4 custom dimensions) - the count is capped by the plan; unregistered parameters are accepted but not stored. RetentionDays is how long per-player event data is kept (default 90, capped by the plan); daily title summaries are kept forever. AutomaticEvents (default on) accepts the SDK's automatic events: idos_first_open, idos_session_start, idos_app_update, idos_os_update, idos_screen_view.
