SessionDB could leave native SQLite handles open when construction failed partway through schema/pragma/FTS/repair/lock/interrupt handling. Other short-lived callers (MCP reads/polling, session search, reactions, trace upload, insights, shutdown recovery) opened temporary SessionDB handles without a complete ownership boundary. API-server profile caches and RetainDB shutdown had similar late-close races. Under sustained load this exhausted file descriptors (EMFILE). - Close partially initialized SessionDB connections on every constructor exception path via a finally block guarded by an initialization-complete flag. - Close temporary/cross-profile SessionDB handles in finally blocks across CLI, MCP, search, trace, reactions, insights, and recovery paths. - Add API-server per-profile cache ownership and disconnect cleanup. - Make RetainDB writer-queue shutdown exception-safe: track connections per thread, close on worker exit, reject new enqueues after shutdown starts, and sweep any connections left by short-lived threads. - Add regression coverage for constructor failures, worker-thread readers, API disconnect failures, shutdown recovery, RetainDB late enqueue, and foreign-loop async clients. Salvage notes: the original PR's per-thread WAL-reader ownership changes were superseded by main's read-connection pool (permits + checkout/return); its cron timeout-abandon fix is credited separately to #72822's earlier identical fix.
