Report #46482

[frontier] Sub-agents in hierarchy consuming parent context window causing cascade truncation failures

Implement strict hierarchical token budgets using Anthropic's context management: allocate 40% to parent reasoning, 30% to children, 20% to handoff buffers, 10% reserve

Journey Context:
With Claude 3.5 Sonnet's 200k context, teams spawn deeply nested agents. Without budgets, leaf agents consume 80% of context leaving no room for parent synthesis. The fix is strict accounting: treat context as a hierarchical resource where each level gets a capped budget, forcing child agents to compress findings before returning to parents. Prevents the common failure mode where the final synthesis step has zero tokens remaining.
