Contributing

Working on mscompress. The repo has three buildable surfaces, all backed by the same C core.

• Development setup — cmake, uv, npm
• Running tests — ctest, pytest, vitest
• Memory leak workflow — Valgrind and macOS leaks
• Versioning — .cz.toml and cz bump
• CI overview — what the build matrix covers

Adding an algorithm

See the implementer guide — touches src/algos/, src/algo.c, src/mscompress.h, and adds tests in all three test suites.
