## @asyncapi/avro-schema-parser

The Avro → JSON Schema conversion in `src/helpers/avro/avroToJsonSchema.ts`
is ported from
[@asyncapi/avro-schema-parser](https://github.com/asyncapi/avro-schema-parser),
Copyright the AsyncAPI Initiative, licensed under the Apache License 2.0.

Modifications made in this port: synchronous API, removal of the `avsc`-based
validation (replaced by a lightweight structural validator), record-cache
threading through array/map positions, and caching named records as JSON
Schema objects.

## @asyncapi/protobuf-schema-parser

The Protobuf → JSON Schema conversion in `src/helpers/protobuf/`
(`protoToJsonSchema.ts`, `primitiveTypes.ts`, `googleTypes.ts`,
`protovalidate.ts`, `protocGenValidate.ts`, `pathUtils.ts`) is ported from
[@asyncapi/protobuf-schema-parser](https://github.com/asyncapi/protobuf-schema-parser),
Copyright the AsyncAPI Initiative, licensed under the Apache License 2.0.

Modifications made in this port: retyped against aui's `SchemaNodeData`
(dropping the `@asyncapi/parser` type imports), fail-soft plugin `parse()`
(returns an error marker instead of throwing), proto3 syntax detection from
the raw source (protobufjs ≥7.5 no longer exposes `root.options.syntax`),
fixed reversed `Path.resolve(origin, include)` args when reporting unresolved
imports, renamed modules, and strict-TS/lint cleanups (`any` casts narrowed).

The license below applies to both ports.
