Product purpose: Redress lets users file structured harm claims against services, DAOs, products, communities, or contributors. Instead of a binary "guilty or not guilty" ruling, GenLayer validators interpret the complaint, the respondent's answer, the evidence, the venue policy, and the requested remedy, then decide what form of redress is fair: full or partial refund, fixed compensation, service credit, public or private apology, correction, acknowledgement, dismissal, or escalation to human review. Not every harm needs punishment. Not every complaint deserves payout. But every serious claim deserves structured interpretation. What belongs on-chain: - venue registry, scope, policy reference, and compensation pool - complaint case records and their lifecycle status - respondent replies and settlement offers - locked evidence packets (URLs / references, not raw files) - GenLayer consensus redress verdicts - settlement and symbolic-completion records - wallet activity index and audit trail What stays off-chain: - full evidence files, screenshots, contracts, chat logs. Only URLs or references belong here.
