# Reproducible Build Profiles This directory contains committed Make configuration profiles. Each profile selects SoC, CPU/IP, PDK, ISA, CSR support, application, linker layout, and the supported validation tier. `ci/` contains pull-request profiles, `nightly/` adds extended open-source coverage, and `cluster/` contains configurations requiring site tools or PDKs. Start builds from a committed profile rather than setting an unreviewed mix of variables on the command line. For supported profiles and commands, see the root [README](../README.md) and [agent contract](../AGENTS.md).
