 - Fix #65: Check source directories exist before writing to requirements-mxdev.txt. In **offline mode**: missing sources log WARNING and are written as comments (expected behavior). In **non-offline mode**: missing sources log ERROR and mxdev exits with RuntimeError (fatal error indicating checkout failure). This fixes mxmake two-stage installation workflow and prevents silent failures when sources fail to check out.
