OS × runtime at a glance
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.
- no sample at this coordinate yet
- there is a sample here, and nothing of ours has run it at this coordinate yet
- there is a sample here, and our run of it at this coordinate came back clean
- there is a sample here, and our run of it at this coordinate failed
- there is a sample here, and this coordinate records both a passing and a failing run of it
- nothing recorded — unknown, never "works" and never "broken"
- there is a level below this cell — click to open it
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.
Published samples
- go.opentelemetry.io/otel v1.37.0: attribute.Bool This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured. HOWgo.opentelemetry.io/otel/attribute.Bool MIT-0 · 2026-09-16
Compatibility matrix
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.
