Viktor Barzin d6edb747d2 Add structured JSON logging, OTel business metrics, and Grafana dashboard ... Structured logging via JsonFormatter replaces uvicorn's default format so Loki can parse timestamps and fields. 14 business metrics (scrape stats, throttle events, circuit breaker state, cache hit rate, OCR success rate, Celery task lifecycle) are defined in a shared metrics module and instrumented across the scraper pipeline, API, and workers. Celery workers expose a Prometheus HTTP endpoint on configurable ports.		2026-02-14 10:59:12 +00:00
