Throwaway experiments are easy to start. Retiring one safely is not

In a recent post on Dev.to, developer Michael Truong explores the challenges of safely retiring experimental software projects. While modern tooling makes it trivial to spin up prototypes and agent-based workflows, the process of decommissioning them is often fraught with risk. Truong identifies three primary failure modes: preserving provisional hacks as if they were validated product design, deleting resources before unlinking them from documentation, and using unreliable search-based methods to identify deletion targets. To mitigate these issues, the author proposes a structured retirement contract: documenting only validated conclusions in durable, self-contained architecture notes, removing live links to prevent 404 errors, and executing deletions based on a verified, human-reviewed allowlist. The core takeaway is that answering a hypothesis is only the first step; true retirement requires a disciplined approach to prevent legacy 'ghost' data from polluting future development.
