Reference

Precise descriptions of Mapper’s surface. These pages describe; the specification prescribes.

• Descriptor forms: the five shapes a descriptor takes.
• Keyword catalog: every keyword by pipeline stage, with tier and a tested example.
• JSON Pointer profile: pointers, write semantics, array writes, relative references.
• Context and envelope: the evaluator’s working state, the scopes, and the result shape.
• Error model: evaluation errors vs validation reports, accumulation, short-circuit.
• Mapping validation: the validate operation, the report, and diagnostic anatomy.
• Mapper class API: construction, map, and validate.
• Request plugin: mapper-request configuration, descriptor surface, and the parse envelope.
• HTTP API: the mapper-http endpoints and status codes.
• HTTP server configuration: the mapper-http environment, mapping sources, and options.
• Conformance: tiers, the spec, and the test suites.

Every runnable example is executed against the published engine by the site’s test suite.
