**A working, clean-room Snowflake SQL API connector for Rust and coding agents.** It authenticates to live Snowflake accounts (key-pair JWT, PAT, or OAuth bearer), submits SQL over the [SQL API](https://docs.snowflake.com/en/developer-guide/sql-api/index) with no ODBC, no JDBC, and no Tokio, and it both reads and writes live data. On the read side it streams back typed query results, catalog discovery, and lineage; on the write side `query write` runs INSERT, MERGE, UPDATE, DELETE, COPY INTO, and PUT through a dry-run to confirm safety ladder. Results come back as deterministic JSON or `toon`. It ships an agent-ergonomic CLI (`franken-snowflake` / `fsnow`), an optional MCP server, a TUI, and deterministic tests that need no warehouse. The live SQL transport is compiled in with the `live` feature.

TL;DR

The Problem

Snowflake ships official drivers for Go, JDBC, .NET, Node.js, ODBC, PHP, and Python. It does not ship one for Rust. A Rust service, or a coding agent that wants to query Snowflake without standing up a Python sidecar, is left with ODBC bridges, JDBC over JNI, or third-party crates whose dependency graphs pull in Tokio, `reqwest`, and a transitive forest no one audited.

For an agent the situation is worse. Raw SQL plus sca
