Completed Work

P1-3: data.db ↔ sys_books Cross-Reference ✅

Matched: 1,116,600 (36.9%)
Unmatched: 1,907,828 (63.1%)
Total: 3,024,428
cloud_path: Populated for all 1,116,600 matched rows
Index: idx_sys_books_cross_ref recreated, ANALYZE done

P2-6: Dimension Tagging — NEEDS RETRY

Tagged so far: ~5,000 / 3,024,428 (0.2%)
First attempt (limit=500K): Failed with TimeoutError due to competing guji import
Blocker: Another Claude session is running import_guji_final() which caused severe lock contention on PostgreSQL

To retry: After guji import locks clear, run:

cd /home/ai/zhineng-knowledge-system && python3 -c "
import asyncio, logging, json
logging.basicConfig(level=logging.INFO, format='%(asctime)s [%(levelname)s] %(message)s')
async def run():
    from backend.services.content_extraction.sysbooks_tagger import tag_sys_books
    result = await tag_sys_books(
        'postgresql://zhineng:zhineng_secure_2024@localhost:5436/zhineng_kb',
        limit=3000000,
    )
    print('Tag result:', json.dumps(result, ensure_ascii=False, indent=2))
asyncio.run(run())

Remaining TODO

Retry dimension tagging after guji locks clear
Update P2-6 coverage in DATA_ASSET_STRATEGY.md after tagging completes
