A rate-parity anomaly is an unexpected price difference between comparable offers. The first step is proving that the offers are **actually comparable**.

## Trigger

A price difference above threshold appears between channels for the same property and stay.

## Evidence

Capture property, room signature, rate plan, occupancy, meal basis, cancellation, payment timing, tax/fee components, currency, market/residency and observation time.

## Investigation order

Validate property, room/rate equivalence, policy, total-price semantics, currency/market context, timestamp proximity and whether the difference persists.

## False positives

Member, mobile, package, geo-targeted, tax-exclusive and refundable products can create legitimate differences.

## Fix

Correct mapping, normalization or freshness problems when technical. If the difference is genuine channel pricing, record it as an anomaly rather than an implementation defect.

## Metrics

Track comparable-offer coverage, parity-delta distribution, persistent anomaly rate, false positives and channel freshness.

## Prevention

Only alert when an explicit comparable-rate predicate is satisfied.
