Document exact file revision provenance and add real Obsidian scenarios for stale files after restart, parent-folder renames, and parent-folder deletion. Characterise replication queue delays during repeated writes to one document.
Companion to Commonlib c0a84a4. Validation used its packed artefact; the local file dependency remains uncommitted until a published Commonlib version is available.
Use the preferred Obsidian element helper and preseed the real-Obsidian scenario before startup. Register the focused test and strengthen revision boundary coverage.
