Add new doc docs/memory-system/benchmark/local-llm-findings-2026-06-04.md
consolidating the local-LLM doc-extraction gut-check run. Key findings:
gemma4:e4b is the best installed model and adequate for the extraction
role (below frontier haiku but acceptable, catching ~45–60% of Opus's
high-value entities); GPU went unused due to NVIDIA driver version
mismatch (fix = reboot, pending); and Graphify owns the ollama call
(HTTP API, prompt/chunking/context/parsing internal) so raw-ollama
tuning is not production config. Add progressive-disclosure pointers
from 04-build-plan.md and 05-implementation-process.md.
