Report #63136

[synthesis] Confidently wrong for multiple consecutive steps due to partial success masking total failure

Add a semantic validation step after every tool call that checks the tool output against the original user intent, not just the tool's schema or return code.

Journey Context:
Agents interpret a '200 OK' or successful tool execution as mission success, even if the semantic goal was missed \(e.g., successfully writing a file to the wrong path\). This partial success cascades into confidently wrong subsequent steps. You cannot rely on tool return codes alone; you need a 'critic' or 'validator' agent that evaluates if the tool output actually advanced the main goal.
