TLDR

This PR updates the stwo dependency and Rust toolchain from 1.82.0 to 1.83.0. The changes are primarily import path updates from stwo to stwo_prover across the codebase. However, the migration appears incomplete with mixed import patterns that could cause compilation issues.

Code Review Feedback

⚠️ Critical Issue: Incomplete Import Migration

Problem: The PR description mentions updating import paths from stwo to stwo_prover, but the codebase still extensively uses stwo:: imports:

Files with unmigrated stwo:: imports:

• crates/common/src/execution.rs:4-5 - Core field imports
• crates/common/src/instruction.rs - Field imports
• crates/runner/src/vm/mod.rs:14-15 - Core VM imports
• crates/prover/src/lib.rs:42-45 - Core prover imports
• All test files in runner crate
• Documentation files

Expected: All use stwo:: should be use stwo_prover:: based on PR description
Actual: Zero stwo_prover:: imports found in codebase

This suggests either:

1. Incomplete migration - Some imports were missed
2. Incorrect PR description - The actual change is different than described
3. Compilation issues pending - Code may not build correctly

✅ Positive Aspects

Dependency Management:

• Consistent stwo submodule update to 75a6b0ac9bcc7101d8658445dded51923ab2586f
• Proper workspace dependency declarations maintained
• Local patches preserved for development workflow

Toolchain Update:

• Clean update to Rust nightly-2025-07-14
• Consistent across all workspace members

Code Organization:

• No breaking changes to public APIs visible
• Component structure maintained
• Test structure preserved

🔍 Security & Performance Considerations

Security: ✅ No security concerns identified

• Dependency updates are from trusted source (Starkware)
• No new unsafe code introduced
• Cryptographic components unchanged

Performance: ✅ No performance regressions expected

• Core algorithmic logic unchanged
• Field operations preserved
• Proof generation pipeline intact

❓ Questions for Author

1. Import Migration Status: Should all stwo:: imports become stwo_prover::? Currently none are migrated.

2. Build Status: Does the code currently compile? The mixed import state suggests potential issues.

3. Test Coverage: Are all tests passing with the new stwo version?

📋 Recommendations

1. Before Merge: Clarify and complete the import migration strategy
2. Testing: Run full test suite to verify compatibility
3. Documentation: Update any stwo version references in docs
4. CI: Ensure all checks pass before merging

Overall Assessment: Good dependency update but needs completion of import migration to prevent build issues.

Update mdtest build command to new stwo crate name

The stwo-prover crate was renamed to stwo, but build_and_discover_crates still runs cargo build -p "stwo-prover". After this rename the package stwo-prover no longer exists, so invoking the mdtest runner will fail during the build step before tests can execute. The package argument should be updated to -p stwo (or otherwise adjusted) so the helper builds the correct dependency.
