20B Full Lifecycle Summary

Gate Mục tiêu Kết quả
P1 Khóa vòi (stop KB upload) ✅ env flag, reversible
P2 Kiểm kê 1.175 docs ✅ manifest + recovery basis
P3 Xóa sạch KB + search regression ✅ 1.175/1.175, 0/35 pollution
P4 Cron FS retention 7 ngày ✅ wrapper + cron, 79 dirs cleaned

Trước 20B: Search bị 1.175 context-pack docs chiếm top results. FS tích lũy 141 builds vô hạn.

Sau 20B: KB context-pack = 0. Search canonical docs top-5 cho 7/7 queries. FS auto-dọn hàng đêm, steady-state ~56 dirs / ~10 MB.


Còn lại (không thuộc 20B)

Việc Mức ưu tiên Ghi chú
Đ43/20Ckb_mirror_status semantics Medium PG manifest vẫn ghi live dù upload disabled. TD từ P1.
20C — KB Governance Framework (tiers, TTL, quota) Low-medium Phòng tái phát cho doc types khác
20A — Search filter defense-in-depth Low Context-pack đã sạch, filter chỉ là guard
Đ44 IU pipeline — Pack 2B/2C Tùy User Đã có design, P2B-P0 prompt sẵn sàng
