-- ADR-090-D: MASTER §7.1 北極星 KPI 資料源建立
-- 建立時間: 2026-04-18 晚 (台北時區)
-- 建立者: ogt + Claude Opus 4.7 (1M)
--
-- 背景:
--   MASTER §7.1 15 個 KPI 對標發現 4 張關鍵表根本沒建立,導致以下 KPI 永遠
--   量不到:
--     #3 fine-tune JSONL /week    → finetune_exports 表
--     #6 Declarative 修復使用率   → remediation_events 表
--     #10 notification_outcomes   → notification_outcomes 表
--
--   此 migration 補齊 3 張資料源表(idempotent)。
--
-- 對應 MASTER § 指標:
--   §3.3 D3 修復抽象(Imperative → Declarative)
--   §3.4 D4 學習深度(Fine-tune)
--   §3.6 D6 自我治理(通知品質)
