There are a lot of places in Lodestar codebase that assume 3 intervals per slot and thus hard code 3 when calculating seconds into the slot.

In preparation of ePBS, or future protocol upgrades that might potentially introduce more intervals per slot, we should refactor our codebase to remove such assumption.

  • Reword variable naming and comments such as one-third, two-third
  • Modify calculations that have 1 / 3, 2 / 3 hardcoded
  • Introduce enum SlotInterval to explicitly lay out what validator actions should happen at which interval
