John DoeandDevin AI a35bcd6647 M4: ingestion management (incremental, GS1 supplement, dedup/conflict, quality, scheduler)
CI / Go (api) (pull_request) Has been cancelled
Details
CI / Python (ingestion) (pull_request) Has been cancelled
Details
CI / Migrations (postgres) (pull_request) Has been cancelled
Details 
- OFF incremental fetch via search API + persistent watermark (ingest_state, migration 0004)
- GS1 barcode supplement adapter (offline mapping + GS1-style API) filling only gaps with field-level provenance
- Non-GTIN dedup with canonical selection + merge_log; field-level conflict resolution (source trust > recency)
- Quality scoring (0.4 completeness + 0.3 source trust + 0.2 multi-source + 0.1 freshness) wired into load/merge
- Jobs: update_off, dedup, schedule; docs/ingestion-management.md
- 19 new tests (pure + DB-integration), ruff clean

lixuandDevin AI e750501b44 feat(M3): 只读 API 端点实现
CI / Go (api) (push) Has been cancelled
Details
CI / Python (ingestion) (push) Has been cancelled
Details
CI / Migrations (postgres) (push) Has been cancelled
Details 
- store: pgx 只读数据访问层(productByGTIN/ByID/search/nutriments/msrp/brands/categories/source)
- handler: 真实查询替换 501 占位, 统一分页 + 错误信封, MSRP 带免责声明无购买入口
- main: pgxpool 连接池接线
- search: 名称模糊 + 分类子树过滤(ltree <@)
- 测试: healthz/pageParams 单测 + DB-backed handler 集成测试(无库自动跳过)
- CI: Go job 增加 postgres service + migrate up, 实跑 DB 测试
- 依赖: pgx v5.7.2 (固定到兼容 go1.23 的版本)
- 本地实跑: 8 个端点对真实 OFF 数据返回正确(barcode/search/nutriments/msrp/brands/categories/source/404)

lixuandDevin AI 766a573989 feat(M2): Open Food Facts 采集导入 ETL 
- adapters/openfoodfacts.py: OFF API 适配器(限速+User-Agent) + JSONL/.gz dump 读取
- etl/transform.py: 纯函数转换(GTIN 校验/净含量解析+归一/营养 per_100g 双能量/过敏原添加剂清洗/关键词分类映射)
- etl/load.py: psycopg upsert(product/food_detail/product_image) + product_source 字段级溯源
- jobs/seed_off.py: CLI(--barcodes API / --dump 文件 / --limit)
- 测试: 13 个离线 transform 单测(fixture) + 可跳过的 DB 集成测试
- 依赖: 增加 psycopg[binary]
- 实跑: 从 OFF API 拉 5 个真实条码入本地 postgres 验证通过
- docs/etl-openfoodfacts.md: 流程/运行/字段映射

lixuandDevin AI b0b816b0ee feat(M1): 数据模型迁移 + GS1 GPC 食品分类 + 单位字典 
- migrations/0001_init: 全部核心表(product/food_detail/product_msrp/product_source/brand/manufacturer/category/category_schema/unit/attribute_definition/product_image/merge_log) + 索引(gtin唯一/name trigram/JSONB GIN/category ltree/tsvector) + tsvector/updated_at 触发器
- 0002_seed_units: 单位字典(与 units.py 一致, 含中文别名) + 常用营养参数定义
- 0003_seed_categories: 食品品类骨架(GS1 GPC 映射 + 自建中文树, ltree) + 品类参数模板(营养基准 per_100g/ml)
- CI 增加 migrations job: 用 postgres service 跑 migrate up + down 验证可逆
- 本地实跑 up/down/re-up 全部通过

lixuandDevin AI 786b7d3721 feat(M0): 工程地基 - Go API + Python 采集骨架 + CI + 数据契约 
- api/: Go(chi) 只读 API 骨架, /healthz + 版本化路由(占位), Dockerfile, 单测
- ingestion/: Python 采集/ETL 包骨架, units 单位归一化(纯函数+测试), adapter 协议
- docker-compose.yml: postgres + redis + minio + api
- .github/workflows/ci.yml: Go build/vet/test + Python ruff/pytest
- docs/data-contract.md(两端共享契约) + docs/disclaimer.md(不提供购买声明)
- migrations/ 占位(M1 起填充)
