Retry

Purpose

Retry one child after failures, up to a fixed number of total attempts.

Key inputs / outputs

• Inputs: node (TreeNode), maxAttempts (VariableField<int>).
• Outputs: none.

Success / Failure semantics

• A missing child fails.
• A maximum of zero attempts fails without executing the child.
• A successful child attempt succeeds the Retry immediately.
• Failed attempts continue until maxAttempts is reached.
• Retry fails when every allowed attempt fails.

Important limitations

• The attempt limit is read once at the start of each Retry execution.
• maxAttempts includes the first attempt and is clamped to zero or greater.
• Retry does not catch exceptions; existing node and tree error policies remain in control.
