darwin-core iter 5 — plateau confirmed, loop halted

0 improvements, 5 honest skips, 1 attempted noImprovement.

The 6 dimensions sit at:
  sona-adapt:        WASM-opaque, AT-TARGET (0.0041 < 0.005)
  moe-gate:          WASM-opaque, AT-TARGET (0.88 > 0.85)
  skill-distillation: bench-saturated 1.0/1.0 (synthetic ADR-155 bench; real ALFWorld eval needed for next jump)
  causal-graph:      smoke binary 21/21 pass; perf path optimized to 3ms (was 115ms)
  reasoning-bank:    BEIR bench doesnt exercise the ReasoningBank subsystem at all — wrong target
  hnsw-search:       NAPI does not honor efConstruction beyond a cap

Real Darwin wins committed across iters 1-4:
  scripts/bench-skill-distillation.mjs (new)         — ADR-155 bench
  scripts/benchmark-intelligence.mjs --only flag      — infra
  v3/@claude-flow/cli/src/mcp-tools/agentdb-tools.ts — early-exit + dynamic-import cache
  v3/@claude-flow/cli/scripts/run-beir-hybrid.mjs    — bm25 tie-breaker
