SummarySummary

Half of the leaves in the schedule-Half of the leaves in the schedule-quality evaluation require extensive quality evaluation require extensive changes to Space-Time Modulechanges to Space-Time Module

We tentatively estimate that this We tentatively estimate that this work may require two to three work may require two to three months of full-time programmingmonths of full-time programming

Evaluation of the background tasks Evaluation of the background tasks and notifications is based on the and notifications is based on the information unavailable to Space-information unavailable to Space-Time Module, and should probably Time Module, and should probably be outside the modulebe outside the module
