Adding CLAUDE.md with task information for AI processing. This file will be removed when the task is complete. Issue: #10
- Add rust-toolchain.toml to pin nightly-2022-08-22 for stable feature compatibility - Add comprehensive unit tests for constants, flow, hybrid, point, and query modules - Add test coverage job to CI workflow using cargo-tarpaulin with 90% minimum threshold - Update CI to require coverage check before build This ensures that on future updates we will not lose any features by accident, as requested in issue #10.

The CI workflow was using dtolnay/rust-toolchain@nightly which always installs the latest nightly, ignoring rust-toolchain.toml. This caused failures because newer nightlies removed features like const_trait. - Changed all rust-toolchain actions from @nightly to @master - Explicitly specify toolchain: nightly-2022-08-22 in each job - Fixed formatting to match nightly-2022-08-22 rustfmt 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
Cargo.lock was in .gitignore (standard for libraries), but since we require nightly-2022-08-22 which needs older dependency versions, we commit Cargo.lock to ensure CI uses the same locked versions: - proc-macro2: 1.0.43 (not 1.0.104 which requires rustc 1.68+) - quote: 1.0.21 - thiserror: 1.0.31 - log: 0.4.17 - syn: 1.0.99 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
cargo-tarpaulin requires a modern Rust compiler to build (its dependency cargo-platform 0.3.2 uses Rust 2024 edition), but our code needs nightly-2022-08-22 to compile. Solution: Install tarpaulin with stable Rust, then run it with the +nightly-2022-08-22 flag. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
rust-toolchain.toml overrides cargo to use nightly-2022-08-22, which prevents compiling tarpaulin (needs modern Rust). Download pre-built binary instead of compiling from source. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
