Keep evidence classes separate

Definition

self_reported is reported_work, system_observed is observed_work and unclassified is unclassified_work. Classes overlap in time and are never summed. processing_time is the span of a process step and has no evidence class.

Recognise overlapping observations

Suppose a time entry reports 30 minutes and a desktop export observes 20 minutes during the same period. Adding them gives 50 minutes of recorded evidence, but it does not establish 50 distinct minutes of work. The two records can describe overlapping activity.

Preserve the reported columns

For this reference snapshot, keep reported_work, observed_work and unclassified_work separate. Present their evidence bases alongside the values instead of creating a new total by summing them.

processing_time measures a process-step span and has no work evidence class. Use the work-time evidence guide to decide what a source actually records, and select one scope before comparing aggregates. Newer measure articles retain their own release scope and definitions.
