kbdb-base SDD §7.5（公庫/私庫雙向機制，richblack 2026-06-07 拍板）。
## KBDB Base worker（新）
- kbdb/：D1-only 核心三表（entries/templates/entry_values）+ CRUD + LIKE search
+ recipe-stats 端點（市場數據）+ 0001_base.sql migration（含 recipe_stat seed）
## Phase 2.3：init 建 D1 + 套 migration
- cli cf-api.ts 加 listD1Databases/ensureD1Database；init 建 arcrun-kbdb D1
- deploy.ts 部署後對 D1 套 0001_base.sql（CF /d1/query API，idempotent）+ 注入 database_id
## Phase 5.1：recipe 成功記錄（市場數據來源）
- GraphExecutor 收集本次用到的 recipe uuid（usedRecipeKeys）
- executeWebhookGraph 執行結束一次性記 per-uuid 成功/失敗到 KBDB（fire-and-forget）
## Phase 7.5：recipe UUID 身份 + app-store 模型
- recipe 領 uuid=唯一身份；canonical_id/author/公私=屬性（§7.5.5）
- recipe:{uuid} + idx:canonical/installed/hash；resolveRecipe 向後相容不破執行鏈
- POST /recipes/submit=領新 uuid 新增作者版本（非覆蓋，app-store）
- GET /public-recipes 搜尋（多作者+per-uuid 市場星數）/ :id pull（選市場最佳）
- 落空→found:false 創作引導（§7.5.6 閉環）
- POST /recipes/migrate-uuid 一次性轉舊 key（增量寫不刪舊、冪等）
- init-seed 用 UUID（author=system）
## 薄殼（rule 07 §5：CLI + MCP 覆蓋同組能力）
- CLI: acr recipe search/pull/submit-p（config 加 DEFAULT_PUBLIC_LIBRARY_URL）
- MCP: arcrun_recipe_search/pull/submit_p/push/list/delete（補齊漂移）
## 壓測修正
- api-recipe-seeds: google_sheets_append PUT→POST（:append 正確動詞，階段12）
四 worker tsc 全綠（cypher/cli/kbdb/mcp）。
