هل يمكن لأحد استكمال مشروع تركه مطوّر آخر؟

The audit exists because quoting a rescue without reading the code is how rescues turn into second failures. Three days of reading is cheaper than three weeks of discovering.

What the audit checks: whether the data model can support what you still want to build, how authentication and permissions are actually enforced, what is deployed versus what is in the repository, dependency and security state, and how much of the work is undocumented knowledge that left with the previous developer.

The honest outcome is sometimes that a rewrite of one module costs less than repairing it. The report says which, with the reasoning, so the decision is yours rather than a matter of trust.
