jerboa-duckdb

jerboa-duckdb is an independent DuckDB-compatible analytical database being implemented in Jerboa Scheme. DuckDB is used as a pinned development oracle and is not linked into the production engine.

The governing scope and delivery gates are in Project.md. The current code implements the first Phase 0 slice: reproducible upstream contract inventory.

Requirements

• jerbuild on PATH
• DuckDB checkout at /Users/user/duckdb, or set DUCKDB_SOURCE
• git for upstream revision verification

Commands

make contracts        # regenerate the checked-in upstream inventory
make contracts-check  # verify revision and deterministic generated output
make unit             # run Jerboa unit tests
make check-docs       # check Markdown hygiene
make verify           # run all current gates

The compatibility ledger begins at contracts/compatibility.sexp. No SQL execution or storage compatibility is claimed yet.
