// Takes two labels:
// algorithm:
// The algorithm used to calculate the state or the step it failed on if it failed.
// algorithm:
// The algorithm used to calculate the state or the step it failed on if it failed.
// Labels starting with "_" are used to indicate when the algorithm fails halfway.
// outcome:
// Whether the state was successfully calculated.
//
// The possible values for algorithm are:
// empty_state -> The list of events was empty so the state is empty.
// no_change -> The state hasn't changed.
// single_delta -> There was a single event added to the state in a way that can be encoded as a single delta
// full_state_no_conflicts -> We created a new copy of the full room state, but didn't enounter any conflicts
// while doing so.
// full_state_with_conflicts -> We created a new copy of the full room state and had to resolve conflicts to do so.
// _load_state_block_nids -> Failed loading the state block nids for a single previous state.
// _load_combined_state -> Failed to load the combined state.
// _resolve_conflicts -> Failed to resolve conflicts.
