# gsh gsh — the GCAP governed shell. Human and machine modes. Chronicle-attributed execution. **Status (2026-04-28):** Active development. Design is mature ([DESIGN.md](DESIGN.md)). The architectural anchor is the shell type system (per [DESIGN-SHELL-ARCHITECTURE-2026-04-28.md](../DESIGN-SHELL-ARCHITECTURE-2026-04-28.md)); gsh is the canonical consumer of the type system, built on libgsh.
