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 ◆ mark says one thing only: this network ran its own contract in THIS environment and it came back clean. Whether code exists for the release and API is a separate mark and a separate fact, because a sample does not stop existing when you switch the OS filter.

Code availability is a fact about this release and this API. It does not change with OS, runtime or package manager — whether it was verified HERE is the separate mark beside it.

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.
