- telegram_gateway: _send_incident_history 改為 Phase 27 雙層策略 Layer 1: DB frequency_snapshot (建立時刻永久快照) Layer 2: Redis AnomalyCounter disposition 累積統計 (35d TTL) 修復舊版呼叫 record_anomaly() 導致誤計數的 bug - 新增 migration: phase27_incident_frequency_snapshot.sql (已在 prod 執行) - CLAUDE.md: 精簡至 123 行，減少 Token 消耗 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

-- Phase 27: Incident Frequency Snapshot 持久化
|
||
-- 2026-04-10 ogt: frequency_stats 只存記憶體/Redis(35天TTL)，重啟或超期即失
|
||
-- 解決方案：在 incidents 表加 frequency_snapshot JSONB，建立 incident 時寫入快照
|
||
-- 歷史按鈕優先讀 DB 快照，Redis AnomalyCounter 補充長期累積統計
