#observability

Trace travel transactions from search through booking and servicing using correlation IDs, distributed traces, metrics and structured domain events.

Build an explainable travel-provider health score using latency, success, freshness, price accuracy, coverage and handoff quality.

Trace a travel offer from supplier response through normalization, cache, ranking and booking handoff with explicit lineage identifiers.

Build an operational KPI model for metasearch covering supplier health, price quality, mapping, latency, click handoff, conversion and freshness instead of monitoring only uptime.
