Release 2026.4 (#614)

[mariusarvinte]

🎉 Major Updates

• Hybrid C-Rust building: as translation progresses with every symbol, the tool now attempts to build a hybrid C-Rust artifact, and execute all tests (if available) using it. If at least one test fails, the translation of the current symbol is considered a failure and re-attempted. This represents a significant upgrade compared to just using cargo build as a correctness signal.
• Library test generation with the Berkeley KISS framework: we dispatch an autonomous RelentlessAgent to analyze a C target, collect input/output pairs, and write assertion tests for it in the Rust C FFI. The output tests are lite-verified for correct file locations, and can be used for the hybrid C-Rust build testing.
• Translating symbol cycles: our tool can now identify and jointly translate symbol cycles with length >1. Post-translation, C FFI wrappers are still generated per-symbol.

🎈 Minor Updates

• Migrated Rust workspace initialization and version control to the fully Python-based ideas.init.workspace module.
• Initial version of an sqlite3-backed symbol cache for resumable translations.
