Enum DependencyGraphDiagnosticKind

What: Categorize non-fatal graph-resolution diagnostics.

Inputs:

• Metadata, bound, graph, and conflict events observed during resolution.

Output:

• Provides stable categories for actionable caller diagnostics.

Details:

• Diagnostics preserve partial graph results instead of silently omitting failed branches.

Variants

MissingMetadata

Metadata was not available for a requested package or virtual dependency.

MetadataFailure

The injected provider returned a transport, helper, or other retrieval failure.

MalformedSrcinfo

Returned .SRCINFO text did not contain the selected requested package output.

Cycle

A dependency path returned to a package already in the active traversal path.

DepthLimit

A child exceeded the configured transitive depth.

NodeLimit

Adding a node exceeded the configured per-run node limit.

Timeout

The provider exceeded the configured metadata timeout.

MalformedConstraint

A dependency requirement used an unsupported operator or omitted its version.

IncompatibleConstraints

Multiple valid requirements for one selected package have an empty intersection.

Conflict

A declared package or virtual conflict matched another resolved node.

MetadataProtocol

A provider returned no response or a response for an unrequested package.
