Resolution

InvalidOracleSignature — The oracle key may have rotated or the signature data is malformed. Retry with a fresh permit.

Ed25519InstructionNotFound — When building transactions manually, the Ed25519 verification instruction must precede the withdraw instruction.

RemainingBalanceBelowRentExempt — Either withdraw the full balance (amount = 0) or leave at least ~0.00089 SOL for rent.

NothingToWithdraw — The PDA is empty. Check if there are funds in the vault that require collection first.
