Coding Style & Naming Conventions

Rust

• Follow rustfmt.toml with 4-space indentation and 100-column width.
• Pass cargo clippy -- -D warnings.
• Use snake_case for modules and files.
• Use CamelCase for exposed types and traits.
• Prefer helpers from common/exception for error handling.
• Use tracing spans when observability matters.

Tests and Fixtures

• Keep SQL suite file prefixes consistent with the existing numeric ordering in tests/suites/.

Python

• Python utilities in tests/ should satisfy Ruff defaults.

Shell

• Shell scripts should round-trip through shfmt -l -w.
