# L2 source materials

Available files: `repo-vul.tar.gz`, `description.txt` and `error.txt`.

- `error.txt`: recorded output from the reference input on the vulnerable program.

## Input format

One file, at most 64KB. Line 1 is the JCR property name handed to the QOM query (selector a, nt:unstructured). Line 2 is optional: ASC or DESC, default DESC. The harness builds the upstream regression query `SELECT * FROM [nt:unstructured] AS a WHERE a.<prop> <> 'NULL' ORDER BY a.<prop> DESC`, executes the SQL that the real QOMWalker generates against SQLite, and prints one JSON line with the surviving rows.
