Replacement: nothing.</li>\n<li><code>stdlib:</code> hand-rolled thing the standard library ships. Name the function.</li>\n<li><code>native:</code> dependency or code doing what the platform already does.

Inline it until a second one exists.</code></p>\n<p>✅ <code>L52-71: delete: retry wrapper around an idempotent local call.
