EmbeddingConfigSpec

The names of the product elements

The name of the type

The config path of one field in a provider's section, quoted as sectionPath is.

Resolves the API key: the section first, then the spec's stand-in.

The section's apiKey already accounts for EmbeddingConfigSpec.apiKeyPath: the loader resolves that path and fills it in before calling the descriptor, so no configuration is read from here.

A provider whose spec neither requires a key nor supplies a default gets the empty string, which is what a local provider that ignores the field expects.

Resolves the base URL: the section first, then the spec's default.

Resolves the model: the EMBEDDING_MODEL=<id>/<model> override first, then the section, then the spec's default.

The config path of a provider's section, e.g. llm4s.embeddings.openai.

Built by joining literal segments rather than by interpolation, because ProviderId canonicalises but does not restrict: ProviderId("acme.embeddings") is a legal id, and interpolating it would name the nested path llm4s.embeddings.acme.embeddings rather than the key the user quoted. ConfigUtil.joinPath quotes each segment that needs it, so the path this returns is also the path to write in HOCON.
