 ## [Unreleased]
 
+### Changed
+
+- `laranail::captcha.install` now extends laranail/package-tools' `InstallCommand` and takes
+  laranail/console's display API and run lifecycle from its `InteractsWithConsoleServices` and
+  `InteractsWithConsoleWriter` traits instead of its `Command` base. Name, option, description,
+  listing visibility, output and exit codes are unchanged and pinned by a new contract test. The
+  command is bound in the container because the new base takes the `Package` in its constructor.
+
 ## [0.1.0] - 2026-08-15
