What Constitutes Recovered Data When Restoring Files via CLion Local History?

Question

The task is to evaluate what counts as a recovered project state after restoring a file from CLion's Local History feature.
The Local History change‑tracker records only the selected file contents; it does not capture build outputs, configuration files, database schemas, or external service states, so a restored file may not represent a runnable project.
Verification therefore requires comparing the restored file with its history entry, rebuilding the project, and executing existing tests or a documented smoke check while noting any failures unrelated to the file itself. The key uncertainty is whether matching the file version alone satisfies recovery criteria or whether full project consistency including artifacts and dependencies must also be validated.
Does the restored file version alone guarantee that the project can be built and executed? Must all ancillary artifacts be restored to a consistent state? What evidence must be documented to confirm full recovery?

Restoring a single file from CLion Local History returns only that file’s source content to a prior timestamp. It does not reconstitute the full project environment, so the recovered file alone does not guarantee that the project builds or executes.
Likely explanation vs confirmed facts

Likely: The IDE reverts the selected file to the content recorded in its local history snapshot.
  Confirmed: Local History does not track compiled artifacts, dependency resolutions, database schemas, or remote service configurations. It is stored internally and is independent of version‑control systems like Git.

Steps to verify recovery for this case

Right‑click the file in the Project tool window, choose Local History → Show History, and select Restore the desired snapshot.
  Choose Build → Clean Project, then Build Project. Note any compilation errors.
  Run the project’s test suite or a documented smoke check. Record pass/fail results.
  If the build or tests fail, compare the restored file’s content with a known‑good backup or the Git baseline (if present) to determine whether the issue stems from the file alone or from broader project state.

Missing diagnostic detail: Does the project have external dependencies, build configurations, or generated artifacts that were modified outside the restored file? Confirming this will clarify whether observed failures are expected or indicate a broader recovery gap.
