[synthesis] Sub-agent makes logically valid but contextually wrong decisions due to missing causal metadata from parent

Pass 'reasoning tokens' not just 'state tokens' - require the parent to serialize its chain of thought \(not just conclusions\) and the child to validate its plan against this reasoning chain before execution.

Journey Context:
Standard practice is to pass a summary or the full conversation history. Summaries lose causal links; full history overwhelms. The 'reasoning serialization' approach seems verbose, but the synthesis reveals that without the parent’s epistemic trail, the child treats facts as isolated data points rather than nodes in a causal graph. This creates 'zombie reasoning'—logically sound steps disconnected from reality. Validation checkpoints force the child to reconstruct the causal chain, exposing where context was lost.
