Showing the environments with the most evidence.

Reading a cell: The number is how many recorded observations the rate divides — one build files an observation per stage it reached, so it counts neither builds nor machines nor people. The document beside it is a different fact from a different source: whether a sample exists at that coordinate, and how our own run of it went there.

A document means there is a sample at that coordinate. Whether one EXISTS is a fact about this release and this API and does not change with OS, runtime or package manager; its COLOUR is how that sample ran in the environment you are looking at.

Environment detail

Project-level observations and symbol/contract verifications are counted separately and never combined.

These counts do not distinguish how the symbol was called: overloads, argument shapes and options are pooled together. What a particular call shape does is proven by a sample's contract, not by these numbers.
