Show HN: Ledge.sh – Runnable Markdown Notes

Ledge.sh positions Markdown notes as an execution layer for developers and DevOps, combining documentation with runnable shell, code, SQL, and AI prompts. For CIOs and technology leaders, the strategic significance is the convergence of knowledge management and operational workflow: teams can standardize runbooks, reduce context switching, and execute work closer to the systems they manage, including remote servers and mobile devices. This could improve speed and consistency in IT operations, but it also raises governance, security, and access-control requirements because notes can directly trigger real commands on production-like infrastructure.
