Post-deployment performance degradation in clinical artificial intelligence systems remains a persistent barrier to sustained patient safety and regulatory adherence. Unlike pre-market validation, real-world deployment exposes models to continuous data shifts, input anomalies, and contextual drift that standard retraining protocols cannot preemptively address. This conceptual systems manuscript presents an original error-taxonomy framework designed specifically to identify, classify, and act upon post-deployment error signals, thereby triggering safe, targeted model revisions without disrupting clinical workflows. Synthesizing peer-reviewed evidence, the framework introduces a layered orchestration infrastructure that integrates error taxonomy classification with governance-constrained decision logic. A unique closed-loop feedback topology ensures iterative refinement while preserving traceability for auditability. Three interpretive formulas quantify risk propagation, decision confidence under taxonomic uncertainty, and governance load. The proposed architecture, termed the error taxonomy update and revision framework (ETURF), provides a theoretical blueprint for responsible lifecycle management across imaging, tabular, and multimodal clinical environments. By anchoring revision triggers to clinically interpretable error categories rather than aggregate metrics, the framework advances infrastructural safety in healthcare AI deployment. This work establishes a conceptual foundation for future integration into hospital information systems and regulatory oversight mechanisms.
