Y-trace / SellerTrace
Six entry points

Six doors into the same
system problem.

Each module starts from a visible seller symptom, then traces it back to platform state, responsibility boundaries, missing evidence, and available escalation paths.

01

Catalogue / Listing Integrity

Brand attribution errors, stale catalogue state, variation mismatches, flat-file failures, detail page corruption, and contribution-path failures.

Signal: A field changes without a visible owner. Seller-facing inventory does not match the buyer-facing page.
Catalogue Contribution TrapCorrection-Path FailureAsymmetric Data Purge
02

Returns / Refunds / Carrier

Return labels, Refund at First Scan, SAFE-T claims, reimbursement statements, carrier responsibility, refund-boundary errors, and evidence-state collapse.

Signal: A return authorisation, label creation, carrier scan, refund trigger, and reimbursement route are treated as one state.
Return-State CollapseCarrier Liability MismatchReimbursement Routing Error
03

Featured Offer / Price Engine

Buy Box suppression, external price-comparator errors, eligibility-versus-award splits, internal competitor errors, override failures, and recurring Featured Offer loss.

Signal: The seller appears eligible. The Featured Offer does not appear. A manual fix may hold briefly, then the suppression returns.
Override Without Feedback LoopExternal Comparator MismatchEngine A/B/C Separation
04

Compliance / Account Health

Retroactive compliance notifications, deleted ASINs, historic ASIN associations, unresolved liability, policy contradictions, and penalties applied to records the seller can no longer see.

Signal: The seller is held responsible for a product they no longer list, did not create, or cannot access.
Historic Association PersistenceRetroactive LiabilityDeleted ASIN Persistence
05

Support Routing / Case Handling

Bot loops, wrong-department routing, contradictory instructions, case closure without resolution, support rewrites, and forum escalation as an alternative resolution path.

Signal: Different teams can receive the report, but no team appears to own end-to-end correction.

06

Advertising / Visibility / Search

Ad spend anomalies, sudden rank shifts, browse-node changes, listing invisibility, traffic collapse, and opaque reporting surfaces.

Signal: Visibility changes without a clear seller-side action while ads may continue spending elsewhere.
