> @burrrata: First off, there’s a ton of context here which I’m happy to discuss on a call. Regarding understanding the flow of data processing within SourceCred, it works like this: Every plugin generates a SourceCred graph that is specific to its domain (e.g. [GitHub createGraph](https://github.com/sourcecred/sourcecred/blob/master/src/plugins/github/createGraph.js), [discourse createGraph](https://github.com/sourcecred/sourcecred/blob/master/src/plugins/discourse/createGraph.js)) The graphs are [merged together](https://github.com/sourcecred/sourcecred/blob/507091a9760262d1c45db2b4035d2d5833f91ec0/src/api/load.js#L90-L99) into one canoncial combined graph (including identity resolution) We then [compute timeline cred on that graph](https://github.com/sourcecred/sourcecred/blob/507091a9760262d1c45db2b4035d2d5833f91ec0/src/api/load.js#L109) using the [TimelineCred class](https://github.com/sourcecred/sourcecred/blob/ddf07c67144b24803898715d16634495068121cc/src/analysis/timeline/timelineCred.js) The weightEvaluator i…
