Package clone deep-clones the string-keyed configuration domain so a caller cannot mutate a value it handed across a public ownership boundary.

Package collision detects sibling configuration keys whose canonical (separator- and case-insensitive) forms collide, within a single tree and recursively through nested objects and arrays of objects.

Package layers builds and resolves the YAML configuration layers: it parses documents with two Viper instances, folds the overlay onto the base with MergeConfigMap after aligning cross-spelled keys canonically, resolves and validates the landscape token, and safely resolves a file-mode overlay path.

Package nilguard reports whether an interface value is nil or a typed nil (an interface wrapping a nil pointer, map, slice, func, or channel), so a public API can reject a missing dependency with a deterministic error instead of panicking on it.

Package resource derives the schema resource identifier a composed configuration block is mounted under.

Package schemaview turns an authored draft-2020-12 configuration schema into the form the validator actually evaluates, so that one equivalence relation governs both sides of validation.

Package tree resolves dotted configuration keys against a merged map using the family's canonical, casing-insensitive key matching.

Package valid compiles a composed JSON Schema, normalizes a configuration instance, validates it, and renders failures as problem-typed errors.
