Configuration Validator and Semantic Diff Studio

Validate strict JSON/YAML, apply pinned schemas, generate a verified RFC 6902 patch and fingerprint RFC 8785 canonical configuration.

Accuracy contract: Syntax is evaluated by strict JSON or YAML 1.2 parsers, schemas by JSON Schema 2020-12, and semantic differences by deterministic JSON Pointer traversal.

Inputs

Defined calculation contract

Document syntaxAuto detects JSON by its first token; otherwise uses strict YAML 1.2.Current documentConfiguration to parse and optionally validate.Proposed documentOptional document parsed with the same syntax and compared semantically.JSON Schema 2020-12Optional strict JSON Schema. Schema and format errors are reported separately from syntax errors.Offline schema packOptional version-pinned schema evaluated without network access. Leave custom schema empty when a pack is selected.
