method = "Direct Tier 2 (no Tier 3 delegation)"
rationale = "The synthesis task requires cross-cluster integration across 12 child reports (~13000 LOC total) which exceeds the Tier 3 worker's effective context window for cross-reference synthesis. The synthesis output (per_video_summary.md + report.md) is mostly Tier 2's own composition work; delegating to Tier 3 would not provide domain expertise gain and would burn excessive tokens."
alternative_considered = "Delegate to Tier 3 worker with 12 child reports as inputs"
alternative_rejected_reason = "Tier 3 worker has stateless context amnesia; the cross-cluster integration requires sustained multi-child reasoning that Tier 3 cannot reliably reproduce. Cost-benefit analysis: Tier 2 direct synthesis is ~5-10x more token-efficient than Tier 3 delegation for this specific task shape."
