+# ADR 005 — Branch-Preserving Story History
+
+**Status:** Accepted in principle; implementation pending Phase 0
+
+## Decision
+
+Returning to an earlier story point should preserve abandoned future history as another branch rather than destructively erasing it.
+
+## Context
+
+The user must be able to recover from unwanted story developments and explore alternatives while retaining prior work.
+
+## Alternatives Considered
+
+- destructive undo,
+- overwrite-in-place editing,
+- complete copy of campaigns for every retry,
+- branch-preserving turn graph.
+
+## Reason
+
+A branch-preserving history provides recovery, experimentation, and auditability without unnecessary campaign duplication.
+
+## Consequences
+
+- turn identity/parentage must be first-class,
+- state restore must be branch-aware,
+- retry/edit semantics must be explicitly defined,
+- the selected candidate repository must either support this or be adaptable to it.
