Conservatively repair JSON syntax or convert JSON and safe YAML while recording
Conservatively repair JSON syntax or convert JSON and safe YAML while recording every repair. Remove only BOM, complete JSON markdown fences and trailing commas outside strings; abstain on ambiguous or unsupported data. Up to 16000 UTF-8 input bytes, depth 24 and 4000 values. No invented values, semantic validation or code execution. Numeric values that cannot be preserved without rounding return explicit abstention.
