Code Museum
Noun · Slang & Abbreviations
Definitions
A repository or system kept around mostly as historical reference rather than for active use. In engineering slang, a code museum can be educational, but it also becomes a problem when nobody is sure whether the exhibits are still wired into production.
In plain English: A preserved collection of old code mostly kept for reference.
Example: "The deprecated integrations repo was basically a code museum, useful for remembering old partner formats but dangerous because a few scripts still quietly ran from it."
