Fix USDS Borrow Rate to Match Sky Savings Rate

The proposal describes a single, narrow action: adjusting the USDS Slope1 interest rate parameter to 0.75%, referencing a specific payload contract implementation on GitHub. The decoded calldata shows exactly one action: a call to execute() (fallback) on a contract address that is consistent with the typical Aave governance payload pattern, where the actual parameter-setting logic lives inside the payload contract rather than being visible as explicit calldata arguments. Because the decoded action carries no arguments, it is not possible to directly verify from the calldata alone that the slope1 value being set is exactly 0.75%, or confirm that 'all other parameters remain unchanged' as claimed. This opacity is standard for this proposal format, so it should not be treated as evidence of a mismatch, but it does limit verification confidence. There is no sign of target mismatch, extra actions, omitted significant actions, or misleading phrasing based on what can be observed. Given the one-to-one match between the single described change and the single decoded action, and no indication of conflicting values or additional undisclosed actions, the proposal is assessed as consistent, but confidence is low because the decoded calldata does not expose the actual numeric parameter change for independent verification.
