Part 6 closes the series by looking at the web application, deployment boundaries, correction workflow, limitations, operational tradeoffs, and what it takes to ship the detector as a usable system.
Part 5 follows the live identification pipeline: detection, OCR, Scryfall lookup, DINOv2 art matching, error propagation, and why the system needs more than a detector.
Part 4 explains how to read detection metrics in this project: precision, recall, mAP50, mAP50-95, per-class behavior, confusion patterns, and what the numbers imply for real product use.
Part 3 explains how the MTG detector is trained: transfer learning, augmentation, optimization, early stopping, local CPU training, cloud GPU experiments, and the research behind each choice.
Implement end-to-end observability for polyglot GraphQL federation with OpenTelemetry, Tempo, Prometheus, Loki, Alloy, and Pyroscope, including tail sampling, SLOs, and cross-signal correlation.
How two gateways compose into a secure, observable API layer with intelligent query planning across subgraphs.
Part 2 examines the dataset behind the MTG detector: splits, YOLO labels, class design, annotation noise, and why data quality sets the real performance ceiling.
GraphQL is not the only protocol in a federated platform. This article explores how gRPC handles internal Java-to-Java communication while REST powers Stripe payment integration in Go.
