Stale-approval exposure on deprecated router

QuickSwap's assessment for RD-F-168 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

Router01 is deprecated per QuickSwap docs but is stateless (holds no user funds by design). Stateless routers cannot drain user funds without explicit user approval and initiation. Old QUICK token has a stale approval surface from the TokenSwap converter but TVL is minimal. No material stale-approval risk from deprecated QuickSwap contracts.
