+# 09 Ticket Hierarchy and Parent-Child Relationships
+
+## Goal
+
+Implement the parent-child ticket model, including nested parent trees and validation around which tickets are allowed to act as parents.
+
+## Requirements
+
+- A ticket may have zero or one parent ticket.
+- Only tickets of type `Parent` may be selected as a parent target.
+- A `Parent` ticket may itself have a parent ticket.
+- `Task` and all other non-`Parent` types may have a parent but may not act as a parent.
+- Parent tickets must show their children in a structured list.
+- Nested child structures must be visually understandable, for example through indentation.
+
+## Acceptance Criteria
+
+- Assigning a non-`Parent` ticket as a parent is rejected.
+- A `Parent` ticket can contain child tickets of multiple types.
+- Nested parent chains are supported.
+- The ticket detail view for a parent ticket shows its child tree.
+
+## Out of Scope
+
+- Automatic roll-up calculations
+- Dependency graphs
+- Parent-based board grouping
