check-jsonl: validate JSONL-like lines contain required fields
|
|
|
|
Usage:
|
|
check-jsonl.sh FILE [--require-key KEY ...]
|
|
|
|
Defaults:
|
|
Requires no fixed keys unless --require-key is provided.
|
|
|
|
This is a lightweight gate: it checks non-empty lines look like JSON objects and
|
|
contain required top-level key names. It does not replace a full JSON parser.
