Pull request overview

This PR attempts to fix a transient field issue in the ToolResultBlock class by adding annotations to the isSuspended() method. However, the implementation uses incorrect Jackson annotations.

Key Changes:

• Added @Transient annotation (from java.beans) to the isSuspended() getter method
• Added @JsonInclude annotation (incorrect - should be @JsonIgnore)
• Added import for com.fasterxml.jackson.annotation.JsonInclude

[Copilot]

This import should be com.fasterxml.jackson.annotation.JsonIgnore instead of JsonInclude. The annotation used on line 125 should be @JsonIgnore to exclude the derived property from serialization, following the pattern established in Msg.java.

Suggested change

	import com.fasterxml.jackson.annotation.JsonInclude;
	import com.fasterxml.jackson.annotation.JsonIgnore;

[Copilot]

The annotation should be @JsonIgnore instead of @JsonInclude. The isSuspended() method is a derived/computed property that reads from the metadata field, so it should be excluded from JSON serialization to prevent redundant data. Using @JsonInclude would cause this property to be serialized, which is incorrect.

This pattern is consistently used in Msg.java where all derived properties annotated with @Transient also use @JsonIgnore (see lines 182-183, 195-196, 209-210, etc. in Msg.java).
