Every model in the portfolio degrades, drifts, and becomes stale over time. The lifecycle management architecture ensures this does not happen silently.
Three monitoring dimensions run continuously. Accuracy tracking compares outputs against domain-specific held-out validation sets. Latency tracking monitors inference time per model across device tiers. Drift detection uses FSSVA deviation signals as the primary mechanism. The three dimensions interact: a model may hold accuracy on the test set while drifting in production. An example: the Medication Assistant maintains 97% accuracy on the held-out set, but its FSSVA deviation score increases 15% over six weeks, concentrated in medications approved recently and absent from training data.
Validation confirms and quantifies detected problems. Continuous validation runs against version-controlled test sets. A/B testing validates updated models using domain-specific quality metrics. Clinical validation by healthcare advisors reviews health-domain models against clinical standards.
Model updates distribute to two tiers. Zone 1 devices (Local Panes) receive updates through over-the-air delivery with staged rollout and automatic rollback. Zone 2 regional nodes (Community Panes) receive updates through a managed deployment pipeline with hot-swap capability: the new version loads alongside the current version, traffic shifts gradually from 5% to 100%, and any quality decline triggers automatic reversion. At Zone 1, each device manages its own rollout. At Zone 2, the regional node orchestrates rollout across its subscriber population.
OTA delivery to Zone 1 respects bandwidth constraints: updates are compressed, prioritized by safety criticality, and scheduled for Wi-Fi. Zone 2 updates are pushed through a managed pipeline from build infrastructure, with centralized pause and rollback capability across multiple nodes.
When a model is superseded, the prior version remains as a fallback for 90 days. Every model version carries a training date, data snapshot identifier, validation scores, and deployment history for traceability and regulatory compliance.
