Wrong property mapping attaches a supplier record to the wrong canonical hotel and can corrupt price, image and availability presentation. Because the result may still look plausible, these incidents can survive unnoticed until a traveler lands on a visibly different property.

## Observable symptom

Landing opens another hotel, conflicting addresses/images appear or an offer is listed under the wrong property.

## Evidence

Collect mapping decision ID, source property, candidate set, feature scores, geo distance, addresses, provider IDs and rule version.

## Triage

Validate parsing, candidate generation, dominant features, missed contradictions, manual overrides and rebrand history.

## Failure modes

Name similarity can overpower contradictory geo data, stale manual overrides can survive a rebrand, and provider IDs can be reused or migrated. Treat strong contradictions as hard guards rather than weak score penalties.

## Fix

Detach the bad mapping, invalidate downstream cache/indexes and correct the rule. A one-off manual change does not remove the recurring cause.

## Metrics and prevention

Track wrong mappings, contradiction bypass, overrides and errors by rule version. Keep mapping decisions explainable.
