Improve KYC duplicate detection messaging and review status#2090
Merged
Conversation
…/activate Didit's new duplicate IP and duplicate device filters surface as DUPLICATED_IP / DUPLICATED_DEVICE risks in the ip_analyses block, which the backend already extracts into kycWarnings. Map both tags (plus POSSIBLE_DUPLICATED_USER, ID_DOCUMENT_IN_BLOCKLIST) to UNRETRYABLE_FRAUD_RISKS so step 1 shows "We couldn't approve your application" with the specific reason and a "Contact support" button instead of the default "Retry KYC" that would just hit the same filter again.
Didit's duplicate IP / duplicate device filters are configured to send suspicious applicants to In Review (not Declined) so they don't reach Rain. Backend already maps that to kycStatus=UNDER_REVIEW with the warnings preserved, but the UI was returning the same generic "being reviewed, takes a few minutes" copy regardless. Render the per-warning reasons when present so the applicant knows what's being checked; keep the original copy as the empty-warnings fallback.
…nings The duplicate IP / duplicate device filters in Didit send applicants to In Review, never to Declined, so the REJECTED-with-fraud branch added in fc97af8 never fires in practice. Pull the UNRETRYABLE_FRAUD_RISKS set, hasUnretryableFraudWarning helper, handleContactSupport callback, and the alternate REJECTED description; keep the new DUPLICATED_IP / DUPLICATED_DEVICE entries in DIDIT_WARNING_DESCRIPTIONS and the UNDER_REVIEW description tweak from f0109dd — those are the pieces that actually surface the duplicate reason on /card/activate.
