Notice of Continued Commented Code Amnesty Operations

A letter to the engineer who left the code there because deleting it felt more permanent than version control actually is.

To: The Engineer
From: This Office
Subject: Your Commented Code


We are writing to acknowledge receipt of the commented code block you have chosen to retain rather than delete.

The block consists of seventeen lines preceded by two hash symbols or three forward slashes, depending on the language. It has been in this state since the commit marked "cleanup WIP" which was pushed eleven months ago. The commit message promised this would be addressed.

We understand.

Under the governing rule, a technical shortcut may remain temporary for as long as nobody writes down its expiration condition.

You did not write down the expiration condition. The commented code remains temporary. It has been temporary for eleven months.


We want to be clear that we are not judging this decision. The reasoning was sound at the time of the commenting. The code might be needed again. Version control is technically a safety net, but the practical experience of recovering specific lines from a specific commit three weeks later is not a safety net. It is a fifteen-minute archaeology project with an uncertain outcome.

The commented code is faster. The commented code is there.


The system appears calmer after the commented code amnesty. The team records the symptom as resolved but not the mechanism.

Months later the same condition returns with enough history to make the temporary fix look like architecture.

At that point, the commented code block is no longer commented code. It is a reference implementation. It is documentation. It is the old approach, preserved for comparison purposes, which everyone agrees was a good idea to keep.


No action is required. We simply wanted you to know that we noticed, and that we, too, have left commented code in codebases that deserved better.

The code is still there.

Yours,
This Office
