Summary

Daily AI research digest for 2026-05-07. 8 verified items, 2 conflict flags.

Focus areas covered

• Context engineering (3 items): LongSeeker (op-set for long-horizon search), Impossibility Triangle (theoretical bound across 52 architectures), When Context Hurts (20× ↔ 46% crossover effect)
• Agent orchestration (1 item, 1 cross-area): Uno-Orchestra (learned router, +16 pp over workflows at 10× lower cost)
• Tools & connectors / safety (1 item): AgentTrust (pre-execution gate, MCP server, 95–96.7% verdict accuracy)
• Long-running autonomous loops (1 item): Design Conductor 2.0 (80h fully autonomous accelerator design)
• Reasoning / RL training infra (1 item): vLLM V0→V1 correctness retrospective (ServiceNow-AI / PipelineRL)
• Frontier models (1 item): Anthropic Finance Agents — first tracked Opus 4.7 number (64.37% Vals AI Finance Agent benchmark)

Conflicts flagged

1. Uno-Orchestra (arxiv:2605.05007) vs. Web2BigTable (arxiv:2604.27221) — same supervisor-delegation thesis, learned vs. hand-designed; both report large gains, orthogonal mechanisms.
2. AgentTrust (arxiv:2605.04785) vs. Tool-Use Tax (arxiv:2605.00136) — both intervene at the tool-call protocol layer (safety vs. performance angles); open question whether stacking them compounds the protocol cost.

Local-model corner

• LongSeeker is a Qwen3-30B-A3B fine-tune; comfortable on M5 Max + 64 GB at Q4/Q5 with KV headroom. Op-set design (Skip/Compress/Rollback/Snippet/Delete) is the portable artifact.
