Report #25416

[frontier] Agents execute destructive tools \(delete, transfer, deploy\) immediately after LLM function call without confirmation

Implement confirmation barrier pattern: tool calls are intercepted and staged in 'pending' checkpoint state; execution only proceeds on explicit human/validator signal; UI layer renders pending tool for approval

Journey Context:
Naive agents bind LLM output directly to tool execution. Production requires human-in-the-loop or policy validation for sensitive operations. Pattern: tool calls are 'staged' not executed. Checkpoint state captures intent \(tool name, args, idempotency key\). Separate process validates \(business rules or human\). On approval, tool executes with original key. Prevents 'oops' deletions by hallucinated agents. Essential for fintech/healthcare agents.
