Reconstruction is the act of rebuilding the whole from pieces.
Given sheaf data on patches of a covering on some space we reconstruct the space.
Given usage data of some system we reconstruct users habits.
Given snippets of information we reconstruct the causal narrative.
Reconstruction codifies the essential characteristics.
Reconstructing a space from sheaf data on a covering identifies the preserved the topological properties.
Reconstructing a users habits from usage data identifies the telling characteristics of user experience.
Reconstructing a story from multiple sources' tellings identifies the essential details.
When life gives you observational data of an object with color, texture, and taste complying with what you know about lemons, go ahead and make some lemonade.
