Comment Archaeology
ELI5 - The Vibe Check
The code makes no sense until you find the one comment, buried two functions away, written five years ago, that explains it was built this way because of a vendor bug that got fixed eighteen months later. Comment archaeology is reading through layers of old, half-relevant comments hoping one of them finally explains why the code is the way it is.
Real Talk
Comment archaeology is the practice of reading through a codebase's accumulated comments, including outdated or contradictory ones, to reconstruct the historical reasoning behind current implementation choices. It's often necessary because the original context lived in a conversation, ticket, or person's head that no longer exists, leaving the comment as the only surviving trace.
When You'll Hear This
"Found the answer through comment archaeology, a comment from 2021 explains the whole workaround." / "I shouldn't need comment archaeology to understand why this function exists."
