• BIRD: Data Engineering Weekly Article submission #1 on the official BIRD Mini-Dev leaderboard in SQLite, PostgreSQL and MySQL (81.0 / 72.6 / 72.4 EX). BIRD hidden test set, scored by the BIRD team: 74.34 EX (simple 81.03 / moderate 72.25 / challenging 56.14; leaderboard row pending), dev 84.03 EX.
• Tokens: ~91% fewer schema tokens on 50+ table databases (median, Spider 2.0-lite; BENCHMARKS.md).
• Enterprise: MIT BEAVER warehouses 31-39% EX vs 11.4% for the paper's best setup; LiveSQLBench-Large 34.79% (both self-reported).
• LangChain / LangGraph: SchemagateRetriever is listed in LangChain's official retriever integrations (langchain-schemagate) and works in LangChain and LangGraph agents; also a LlamaIndex retriever and the official MCP Registry. 34.5k PyPI downloads, Apache-2.0.

Suggesting an article for the weekly: an engineering write-up on testing LLM text-to-SQL access control against Spider-ACL (Findings of EACL 2026), whose labels come from real PostgreSQL GRANTs. Running against labels the author did not write exposed a fail-closed bug that had quietly refused valid queries, and the post covers the fix, the full 19,624-record result and its limits.

Disclosure: I wrote the article and maintain the open-source library it tests.
