Diagnose divergence between booking cancellation and payment refund state across amount, currency, partial refunds and provider evidence.

Diagnose stale availability and expired offers across freshness, cache, token and revalidation layers between search and booking.

Diagnose hotel tax and fee differences through explicit base/total semantics, currency handling, occupancy and market context.

Troubleshoot hotel room and rate-plan mapping failures using canonical identity, occupancy, meal, policy and contradiction evidence.

Diagnose stale hotel offers and delayed feeds using freshness timestamps, ingestion lag, cache state and invalidation evidence.
