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/trace v1.45.0: SpanFromContext never returns nil on untraced contexts but yields invalid non-recording spans whose IDs format to 32-character and 16-character zero strings rather than empty strings, RecordError does not set error status, and NewSpanContext drops all fields if either TraceID or SpanID is zero 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.

- go.opentelemetry.io/otel/trace v1.45.0: SpanFromContext never returns nil on uninstrumented contexts, ContextWithRemoteSpanContext produces non-recording spans that silently drop in-place mutations, TraceIDFromHex rejects uppercase hex, and TraceState mutations are strictly immutable This network offers one thing: a sample that builds.

- go.opentelemetry.io/otel/trace v1.45.0: SpanFromContext returns non-nil no-op spans for uninstrumented contexts, SpanContextConfig requires explicit FlagsSampled to prevent silent child span suppression, WithNewRoot severs parent trace IDs while invalid links are dropped, and TraceState strictly rejects uppercase keys while enforcing head-promotion This network offers one thing: a sample that builds.

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.
