Research Summary

Core finding (Grade A, arXiv:2607.20468 InferenceBench): AI agents reach 8.08× inference speedup vs naive PyTorch on H100/2h budget, but the hyperparameter-search ceiling is 11.53× — leaving a 1.43× gap because agents converge on a single inference framework rather than exploring diverse configurations.

Memory finding (Grade A, arXiv:2608.02508 RoMeRL): Self-evolving agent memory with cold-start tracking delivers 80% Cold-Q ratio reduction, 84.4% memory size cut, 21.1% LLM call reduction on real agent benchmarks (ALFWorld, LifelongAgentBench).

ADR-381 proposes:

  1. --diversity-mode for npx ruflo performance benchmark — spawns 4 parallel workers each with a different inference config slice; coordinator selects best. Targets closing the 1.43× convergence gap.
  2. cold-q-prune background worker — tracks Cold-Q ratio in AgentDB post-task, triggers consolidate worker above 0.60 threshold. Expected: ~21% LLM call reduction per cycle.

Scan findings:

  • Security: AttriGuard causal attribution of tool invocations (OWASP LLM01 structural fix without model changes); CP-WBFT 85.7% fault tolerance vs classical 33%
  • Hive-mind: CP-WBFT confidence-weighted consensus; SWARM+ hierarchical localization

Note on prior phantom ADR-381: Issues #2918 and #2902 both referenced "ADR-381" in their bodies as a proposed number for PheromoneBus. Neither filed the ADR file. This PR claims and files ADR-381 for tonight's configuration-diversity finding. The PheromoneBus architectural decision from 2026-08-04 should be filed as ADR-382 in a future cycle.


Merge Policy

Leave for human review. Do not self-merge. This is a research/ADR proposal; implementation work should be tracked in separate feature branches.

…old-Q pruning (ADR-381)

- Add ADR-381: Configuration-Diversity Engine for inference self-optimization
  * Agents converge on single framework, miss 1.43x vs hyperparameter ceiling (InferenceBench A)
  * RoMeRL: 80% Cold-Q reduction, 84.4% memory cut, 21.1% LLM call reduction (A)
  * Proposes --diversity-mode for `performance benchmark` + cold-q-prune worker
- Update v3/docs/adr/README.md with ADR-381 row
- Add docs/dream-cycle/2026-08-05-performance-sota.md research report
