Preserve existing unknown nodes for the unknown restoration pass.
The unknown-node pass at Lines [3440-3466] matches URLs against unknown_active_nodes and unknown_inactive_nodes. This branch runs first for every non-CNR URL, clones into the active path, and marks the URL as processed. Lines [3430-3433] then remove it from git_info. An existing active unknown node can cause a path collision. An existing disabled unknown node can be cloned as a second active copy instead of being enabled and checked out. Skip direct cloning for URLs already represented by unknown nodes, or process the unknown-node pass before new clones.

… the git fallback The final loop that installs any remaining git_custom_nodes entries ignored the result of repo_install() and appended every repo to cloned_repos, so a failed clone was still reported as [ INSTALLED ]. It also never checked out the commit recorded in the snapshot, leaving the repo on the remote's default branch instead of the pinned revision. Check the install result before reporting success, and check out the saved hash after cloning.

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.

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.

Summary
The last loop in restore_snapshot() — the one that installs whatever git_custom_nodes entries are left after the CNR and unknown-node passes — has two problems:
It throws away the return value of repo_install() and appends the repo to cloned_repos unconditionally. A repo that failed to clone still gets printed as [ INSTALLED ] in the summary, and nothing shows up in failed.
It never checks out the commit stored in the snapshot. repo_install() clones the remote's default branch, so the restored node ends up on whatever HEAD happens to be, not the revision the snapshot pinned. Every other restore path in this function goes through repo_switch_commit(); this one doesn't.
The second one is the more annoying of the two in practice — you restore a snapshot expecting a specific revision and silently get a different one.
Fix
Check res.result before reporting success, and call repo_switch_commit() with the hash from git_info after a successful clone. Failures in either step are reported in failed with a message instead of being swallowed.
Test plan
Snapshot with a git entry not matched by the CNR/unknown passes, repo reachable — confirm it's cloned and checked out at the pinned hash
Same, but with an unreachable URL — confirm it lands in failed instead of [ INSTALLED ]
Same, but with a hash that doesn't exist in the repo — confirm the checkout failure is reported
Snapshot where everything resolves through CNR — confirm no behavior change
