C01
JSON format
Pretty-print, minify, sort keys and validate — syntax errors pinned to line, column and offset.
WHAT IT WILL NOT DO
- Numbers pass through IEEE 754 doubles, so IDs beyond 2^53 change silently.
- Duplicate keys keep only the last one, with every repeat listed by position.
- No comments or trailing commas; compare with C05, extract fields with C03.
