Include the clone error in the failed list.

Line [3490] prints res.msg, but Line [3491] appends only repo_name. The final failure summary therefore omits the actual clone error. Append the message to the failure entry, or store a structured failure record, to satisfy the snapshot restoration contract.

Defer post-installation until after the snapshot checkout.

return_postinstall=False makes UnifiedManager.repo_install() execute requirements.txt and install.py before this block checks out commit_hash. A repository whose default branch differs from the snapshot can therefore install different dependencies and execute different code, even when checkout later succeeds. Use return_postinstall=True, check out the snapshot first, then run res.postinstall() with equivalent error handling before adding the repository to cloned_repos. The commit check is present, but it arrives after the package check.

Suggested fix 
-        res = unified_manager.repo_install(repo_url, to_path, instant_execution=True, no_deps=False, return_postinstall=False)
+        res = unified_manager.repo_install(repo_url, to_path, instant_execution=True, no_deps=False, return_postinstall=True)
         if not res.result:
             print(f"[ComfyUI-Manager] Failed to restore '{repo_url}': {res.msg}")
