Wiki edit history is not accessible

What the limitation is
Talkyard tracks revision numbers internally — the revision counter increments on each save — but provides no user-facing interface to view previous versions, compare revisions, or revert to an earlier state. Once a wiki post is edited, the previous content is gone from the user's perspective.

How it was discovered
Editing a wiki post and attempting to view what had changed. No history UI exists.

Impact
This is the most significant limitation for an event-sourced knowledge base. Editing a wiki post is effectively a destructive operation. The evolution of understanding cannot be traced. Mistakes cannot be recovered. Auditing is impossible. The current state appears to have always been the state.

Workaround
None adequate. The workaround would be maintaining external version history, which defeats the purpose of integrated wiki functionality. Currently accepted as a known gap.

Status
No workaround. Accepted gap for interim platform use.
