Adds a closing remark (23 Feb 2026) summarising the final state of the
infospace: 988 entities, 985 evaluations, 823 L2 classifications, 15 L3
relations, viability 6/6 PASS.
New open tasks 20–23:
20. Complete L2 classification batch (165 entities blocked on credits)
21. Run classify-links for 58 Relation-type entities
22. Refresh stale metrics-report.md narrative
23. Smoke-test the graph command end-to-end
Also committed: history.py fix — write_metrics_file now preserves
non-float metric values (type_distribution dict) instead of crashing
on round().
