License: MIT

Topics: error-handling, fortran, json, json-parser, json-parsing, serialization

Classification scope and review notes

JSON parsing and serialization with explicit error values. The main checks numeric/string fields, missing-key reporting, compact serialization round trips and malformed-input rejection. It uses the original Erloff 2.2.0 API with a pinned compatible Strff 3.1.1 and ISO varying string 3.0.3; the Strff 4.0 dependency graph needs an unavailable GitHub mirror. No computational source is patched.
