Changelist

Features

• Allow Advanced-mode users to repay debt with exact liability-vault shares held in another Euler position, identify the source position in the selector, and carry both accounts through planning, projection, simulation, review, and wallet binding; execute safe standalone repayments directly and support reciprocal exits atomically in a batch without liquidity-dependent withdrawals (feat: support cross-position collateral repayment #843) @Seranged
• Serve oracle provider and adapter logos from the managed Data V3 image namespace, add canonical Uniswap V3 mappings, preserve provider-first fallback behavior, and remove duplicate local logo assets and cache configuration (Serve oracle provider logos from V3 #841) @Seranged

Fixes

• Restore direct and multi-operation transaction review in spy mode with deterministic approval-only, read-only preparation, including complete calldata and Tenderly inputs, while keeping reviewed-execution authority unavailable and Execute disabled (Restore spy-mode transaction review preparation #844) @dglowinski

Security documentation

• Add the April 20 and May 23 Phase 2 Euler penetration testing reports under pentesting/, preserving the supplied PDFs byte-for-byte (feat: add penetration testing reports #840) @Seranged
