Todo 53.5: EventPrompt Order-Independent Identity

Problem

Todo 53.4 distinguishes managed and impostor content, but tests only the ordering where the impostor precedes the managed item. An incorrect collector that keeps the last generated-signature item could still pass.

Scope

• Change only the EventPrompt payload behavior test.
• Run the same assertions with managed-before-impostor and managed-after-impostor prompt arrays.
• In both orderings, dual_agent must retain ordinary custom prompts plus the managed content.
• In both orderings, chat_agent_tools must retain ordinary custom prompts only.
• Do not change production code.

Verification

• Focused payload test passes for both orderings.
• Full WebSocket test file, Node syntax, and diff checks pass.
• Repeat the bounded code-quality review.
