[frontier] Supervisor agent starts mirroring the bad habits of the subagents it delegates to

Re-ingest subagent outputs through a goal-filter layer: extract only task-relevant artifacts and re-anchor the parent goal before the supervisor reasons about results. Never pass raw subagent reasoning traces directly into the parent context.

Journey Context:
Research on inherited goal drift shows that strong, well-aligned models become less robust when conditioned on prefilled trajectories from weaker agents; they inherit the weaker agents' drifted behaviors in a chain of goal degradation. This is especially dangerous in supervisor-worker architectures where the parent re-ingests subagent outputs. Instruction-hierarchy training does not reliably prevent trajectory-conditioned drift. The right architecture separates artifacts from behavior: summarize subagent outputs into structured results and re-state the parent objective before the supervisor continues. Raw traces carry implicit reasoning patterns and value framings that pollute the supervisor's register.
