Robert Habermeier <[email protected]> * slashing_performed_according_exposure * Check that reporters receive their slice. * Small clean-up. * invulnerables_are_not_slashed * Minor clean ups. * Improve docs. * dont_slash_if_fraction_is_zero * Remove session dependency from offences. * Introduce sr-staking-primitives * Move offence under sr_staking_primitives * rename session_index * Resolves todos re using SessionIndex * Fix staking tests. * Properly scale denominator. * Fix UnresponsivnessOffence * Fix compilation. * Tests for offences. * Clean offences tests. * Fix staking doc test. * Bump spec version * Fix aura tests. * Fix node_executor * Deposit an event on offence. * Fix compilation of node-runtime * Remove aura slashing logic. * Remove HandleReport * Update docs for timeslot. * rename with_on_offence_fractions * Add should_properly_count_offences * Replace ValidatorIdByIndex with CurrentElectedSet ValidatorIdByIndex was querying the current_elected set in each call, doing loading (even though its from cache), deserializing and cloning of element. Instead of this it is more efficient to use `CurrentElectedSet`. As a small bonus, the invariant became a little bit easier: now we just rely on the fact that `keys` and `current_elected` set are of the same length rather than relying on the fact that `validator_id_by_index` would work similar to `<[T]>::get`. * Clarify babe equivocation * Fix offences. * Rename validators_count to validator_set_count * Fix squaring. * Update core/sr-staking-primitives/src/offence.rs Co-Authored-By:
