What an agent can do with the SQL-mini corpus

apuravmanhas/SQL-mini: VerityTick: PostgreSQL 18 transactional limit order book, double-entry financial ledger, SHA-256 tamper-evident audit chain, recursive CTE

Look up how SQL-mini implements database-engineering, double-entry-ledger, fraud-detection, with answers cited to file and line.
Reuse a worked example: the commit “implement audit chain, fraud analytics, market data, RLS,…” (12 files · SQL, Python).
Answer from SQL-mini's real SQL source instead of memory (Databases and storage engines).

Example questions

How does SQL-mini implement database-engineering?
What does db do in SQL-mini?

Paste it into your AI agent. It clones the repo at the pinned commit and indexes it on your machine.

Search the GitHub repository apuravmanhas/SQL-mini with XERJ (https://hub.xerj.org/corpus/apuravmanhas--sql-mini).
Run these in a shell, in order, and check each result before the next:
1. xerj --help  (success: it prints usage). If xerj is missing: curl -fsSL https://xerj.org/get | sh
2. git clone https://github.com/apuravmanhas/SQL-mini SQL-mini && git -C SQL-mini checkout a47b34b0b6a392e3bac605d85e17a56819c676dd
3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data
4. xerj autoindex ./SQL-mini --url http://127.0.0.1:9200 --prefix sql-mini --progress plain
5. xerj autoindex map --url http://127.0.0.1:9200
Then answer my question from the indexed files and cite the ax_path of every hit. Query syntax: https://xerj.org/llms.txt
