   - compare_configs.py imports DIR_PREFIX_TO_SUITE from aggregate_status.py rather than defining its own copy
   - generate_manifest.py exits 1 when runs/official doesn't exist — expected in worktrees without run data

+## 2026-02-16 - US-004
+- Archived saturated ccb_repoqa benchmark (1.000/1.000 on both configs = zero signal)
+- Moved benchmarks/ccb_repoqa/ → benchmarks/archive/ccb_repoqa/
+- Moved configs/repoqa_2config.sh → configs/archive/repoqa_2config.sh
+- Removed 10 repoqa entries from configs/selected_benchmark_tasks.json
+- Updated benchmarks/README.md: removed from active list, added Archived Benchmarks section, renumbered remaining, updated totals
+- Recalculated metadata in selected_benchmark_tasks.json (total_selected, tasks_per_benchmark, language stats, avg MCP score)
+- Files changed: benchmarks/ccb_repoqa/ (moved), configs/repoqa_2config.sh (moved), configs/selected_benchmark_tasks.json, benchmarks/README.md
+- **Learnings for future iterations:**
+  - `git mv` preserves history for archived directories — preferred over manual copy+delete
+  - selected_benchmark_tasks.json metadata.total_selected was stale (171 vs actual 200) — use Python to recount from tasks array when modifying
+  - DIR_PREFIX_TO_SUITE mappings for repoqa_ were left in place in scripts — archived suites' run data may still exist in runs/official and the scripts should still recognize them
+  - When archiving suites: move benchmark dir, move config script, remove from selected_benchmark_tasks.json, update benchmarks/README.md
