A room/rate mapping failure occurs when a supplier-specific product is attached to the wrong canonical room or rate plan. It can surface as a price discrepancy, wrong imagery, incorrect meal/refundability or a different product after click.

## Observable symptom

A “Deluxe Sea View” room is merged with a “Standard Room”, a refundable product is compared with non-refundable inventory, or breakfast-inclusive and room-only rates share one comparison row.

## Most likely causes by layer

Supplier room IDs may change, text similarity can over-match, bed/view/occupancy attributes can be lost, rate policies may not be normalized, rebrands can leave stale mappings, or automatic rules can overwrite manual corrections.

## Fast triage order

1. Retrieve the raw supplier room/rate object.
2. List the features used for the mapping decision.
3. Retrieve the canonical room/rate target.
4. Expose the score/rules that produced the match.
5. Validate the actual landing product.

## Evidence for acceptance or rejection

Room mapping should not rely on name alone. Use bed type, view, max occupancy, room size, amenities and supplier room ID.

Rate-plan mapping should compare meal, refundability, cancellation deadline, payment timing and board code.

## Diagnostic decision tree

If the property itself differs, fix property mapping first.

If a stable room ID exists, prefer it over text similarity.

If a hard contradiction exists—such as sea view versus no view or refundable versus non-refundable—do not merge.

If confidence remains low, “unknown” is safer than a false match.

## False positives

Localized names, marketing text and supplier abbreviations can differ while describing the same product. The reverse also happens: identical names can hide different beds, views or policies.

## Fix

Separate canonical room identity from rate-plan identity. Persist mapping confidence, matched features, contradictions and source version.

## Validation

After the fix, test attribute parity for offers grouped under the same canonical room and manually sample landing products.

## Metrics proving resolution

Track low-confidence mapping rate, manual-override rate, post-click product mismatch and contradiction rate.

## Prevention

Make mapping decisions explainable and alert when supplier schema or naming changes create mapping drift.
