Orders and storage access can migrate away from direct globals/localStorage without a rewrite.\n2. Order auto-completion is now a server business rule. PostgreSQL cron runs every minute and marks due orders fully paid/completed.\n3. The server updates both normalized sun_v17_orders and the legacy sun_app_state sunOrders payload so existing clients remain compatible during migration.\n4. Signed-in cloud clients no longer execute browser-side auto-completion; the old code remains only as local/offline fallback.\n5. Client server-automation module can request an immediate run on startup/focus and applies changed normalized orders through the data layer.\n6. Error telemetry rejects file:// events, deduplicates identical events for five minutes, and retains only 30 days. Historical file:// events are removed.\n7. Stability logger version is synchronized to 17.7.0.\n8. PWA cache v75 includes data-layer and server-automation modules.\n9. This is phase 1 of the architecture migration; legacy state remains intentionally enabled until subsequent domain-by-domain extraction is complete.\n`);
