&lt;p&gt;Features go in. Compatibility layers remain. Old state keeps its place because removing it feels riskier than carrying it. A temporary endpoint becomes a customer dependency. A migration flag survives long after the migration. A data field whose meaning has changed three times continues to answer because some quiet part of the system still asks for it.&lt;/p&gt;
&lt;p&gt;The usual word for this is technical debt, but debt is too clean a metaphor. Debt has a lender, a balance, and a date on the bill. Software decay is less orderly. It is closer to sediment. Each layer is understandable when it lands, and opaque once enough layers have settled above it.&lt;/p&gt;</description></item></channel></rss>
