 - 2026-07-15 追記：`services/pchome_growth_same_item_reconciliation.py` 已達 880 行；同商品 identity verifier、exact DB readback、coverage post-verifier 與 durable receipt persistence 應在 `ARCH-P1-001` 拆成獨立 policy/verifier/repository，主模組只保留 bounded orchestration。
 - 2026-07-17 追記：Nemotron decision-only canary 的排程執行、Telegram acknowledgement 與 durable receipt 終局已移至 `services/nemotron_decision_canary_scheduler_task.py`（120 行）；`run_scheduler.py` 僅保留薄委派與排程註冊，清冊同步為 1,684 行，下一步仍依序拆 task registration 與 runtime startup。
 - 2026-07-22 追記：業績分析的 canonical query、metric aggregate、Other-category contract 與 period-linked Excel export 已抽到 `services/sales_analysis_query_service.py`（391 行）及 `services/sales_analysis_export_service.py`（207 行）；`routes/sales_routes.py` 降為 2,954 行，後續繼續拆 page context 與 legacy pandas API。
+- 2026-07-22 追記：V10.816 將 exact-digest model candidate/identity policy 抽成 `services/nemotron_runtime_candidate_service.py`（234 行）、process/container-shared ownership-token lease 與 side-effect crash quarantine 抽成 `services/nemotron_dispatch_reservation_service.py`（376 行），decision-only runtime proof 維持在 `services/nemotron_decision_canary_service.py`（604 行）；`services/nemoton_dispatcher_service.py` 因補齊共用 tool contract、durable outcome、commit-failure quarantine 與 privacy-safe fallback footprint增至 2,864 行。此輪先完成 P0 自動化正確性；後續 `ARCH-P1-001` 應依序抽出 delivery outcome adapter、tool execution coordinator 與 footprint renderer，dispatcher 只保留 orchestration。
