## RelayVRFStory
Assignment criteria are based off of possible stories about the relay-chain block that included the candidate. More information on stories is available in [the informational page on approvals.](../protocol-approval.md#stories).
```rust
/// A story based on the VRF that authorized the relay-chain block where the candidate was
/// included.
///
/// VRF Context is "A&V RC-VRF"
struct RelayVRFStory(VRFInOut);
```
## RelayEquivocationStory
```rust
/// A story based on the candidate hash itself. Should be used when a candidate is an
/// equivocation: when there are two relay-chain blocks with the same RelayVRFStory, but only
/// one contains the candidate.
///
/// VRF Context is "A&V RC-EQUIV"
struct RelayEquivocationStory(Hash);
```
## ExecutionTimePair
```rust
struct ExecutionTimePair {
// The absolute time in milliseconds that the validator claims to have taken
// with the block.
absolute: u32,
// The validator's believed ratio in execution time to the average, expressed as a fixed-point
// 16-bit unsigned integer with 8 bits before and after the point.
ratio: FixedU16,
