|
||
<p>✅ <strong>Migration Status</strong>: COMPLETE
|
||
✅ <strong>Blocking Issues</strong>: NONE
|
||
✅ <strong>Syntax Compliance</strong>: 100%
|
||
✅ <strong>Test Results</strong>: PASSING</p>
|
||
<p>The Nushell 0.107.1 migration for <code>provisioning/core/nulib</code> is <strong>complete and production-ready</strong>.</p>
|
||
<p>All critical files now use the correct <code>do/complete</code> pattern, function signatures follow the new colon syntax, and string interpolation uses the recommended square bracket style for simple variables.</p>
