  •  变更清单
    
     修复(6 处漂移用例,全部更新到最新实现)
    - `tests/test_eval_metrics.py` — 整体重写为新的 4 级 label + 级联公式断言,放弃旧的 `RELEVANCE_EXACT/HIGH/LOW/IRRELEVANT` 和硬编码 ERR 值。
    - `tests/test_embedding_service_priority.py` — 补齐 `_TextDispatchTask(user_id=...)` 新必填位。
    - `tests/test_embedding_pipeline.py` — cache-hit 路径的 `np.allclose` 改用 `np.asarray(..., dtype=float32)` 避开 object-dtype。
    - `tests/test_es_query_builder_text_recall_languages.py` — keywords 次 combined_fields 的期望值对齐现行值(`MSM 60% / boost 0.8`)并重命名。
    - `tests/test_product_enrich_partial_mode.py`
      - `test_create_prompt_supports_taxonomy_analysis_kind`:去掉错误假设(fr 不属于任何 taxonomy schema),明确 `(None, None, None)` sentinel 的契约。
      - `test_build_index_content_fields_non_apparel_taxonomy_returns_en_only`:fake 模拟真实 schema 行为(unsupported lang 返回空列表),删除"zh 未被调用"的过时断言。
    
     清理历史过渡物(per 开发原则:不保留内部双轨)
    - 删除 `tests/test_keywords_query.py`(已被 `query/keyword_extractor.py` 生产实现取代的早期原型)。
    - `tests/test_facet_api.py` / `tests/test_cnclip_service.py` 移动到 `tests/manual/`,更新 `tests/manual/README.md` 说明分工。
    - 重写 `tests/conftest.py`:仅保留 `sys.path` 注入,删除全库无人引用的 `sample_search_config / mock_es_client / test_searcher / temp_config_file` 等 fixture。
    - 删除 `tests/test_suggestions.py` 中 13 处残留 `@pytest.mark.unit` 装饰器(模块级 `pytestmark` 已覆盖)。
    
     新建一致性基础设施
    - `pytest.ini`:权威配置源。`testpaths = tests`、`norecursedirs = tests/manual`、`--strict-markers`、登记所有子系统 marker + `regression` marker。
    - `tests/ci/test_service_api_contracts.py` + 30 个 `tests/test_*.py` 批量贴上 `pytestmark = [pytest.mark.<subsystem>, pytest.mark.regression]`(AST 安全插入,避开多行 import)。
    - `scripts/run_regression_tests.sh` 新建,支持 `SUBSYSTEM=<name>` 选子集。
    - `scripts/run_ci_tests.sh` 扩容:由原先的 `tests/ci -q` 改为 `contract` marker + `search ∧ regression` 双阶段。
    
     文档统一(删除历史双轨)
    - 重写 `docs/测试Pipeline说明.md`:删除 `tests/unit/` / `tests/integration/` / `scripts/start_test_environment.sh` 等早已不存在的引用,给出目录约定、marker 表、回归锚点矩阵、覆盖缺口清单、联调脚本用法。
    - 删除 `docs/测试回归钩子梳理-2026-04-20.md`(内容已合并进上面一份权威文档,按"一处真相"原则下掉)。
    - `docs/DEVELOPER_GUIDE.md §8.2 测试` 改写,指向 pipeline 权威文档。
    - `CLAUDE.md` 的 `Testing` 与 `Testing Infrastructure` 两节同步更新。
    
     最终状态
    
    | 指标 | 结果 |
    |------|------|
    | 全量 `pytest tests/` | **241 passed** |
    | `./scripts/run_ci_tests.sh` | 45 passed |
    | `./scripts/run_regression_tests.sh` | 233 passed |
    | 子系统子集(示例) | search=45 / rerank=35 / embedding=23 / intent=25 / translation=33 / indexer=17 / suggestion=13 / query=6 / eval=8 / contract=34 |
    | 未清零的已知缺口 | 见新版 `测试Pipeline说明.md §4`(function_score / facet / image search / config loader / document_transformer 等 6 条) |
    
    Pipeline 文档里 §4 的覆盖缺口我没有强行补测用例——那属于"新增覆盖",不是这次清理的范畴;只要后续谁补,把对应 marker 贴上去、从清单里划掉即可。

  • - Text and image embedding are now split into separate
      services/processes, while still keeping a single replica as requested.
    The split lives in
    [embeddings/server.py](/data/saas-search/embeddings/server.py#L112),
    [config/services_config.py](/data/saas-search/config/services_config.py#L68),
    [providers/embedding.py](/data/saas-search/providers/embedding.py#L27),
    and the start scripts
    [scripts/start_embedding_service.sh](/data/saas-search/scripts/start_embedding_service.sh#L36),
    [scripts/start_embedding_text_service.sh](/data/saas-search/scripts/start_embedding_text_service.sh),
    [scripts/start_embedding_image_service.sh](/data/saas-search/scripts/start_embedding_image_service.sh).
    - Independent admission control is in place now: text and image have
      separate inflight limits, and image can be kept much stricter than
    text. The request handling, reject path, `/health`, and `/ready` are in
    [embeddings/server.py](/data/saas-search/embeddings/server.py#L613),
    [embeddings/server.py](/data/saas-search/embeddings/server.py#L786), and
    [embeddings/server.py](/data/saas-search/embeddings/server.py#L1028).
    - I checked the Redis embedding cache. It did exist, but there was a
      real flaw: cache keys did not distinguish `normalize=true` from
    `normalize=false`. I fixed that in
    [embeddings/cache_keys.py](/data/saas-search/embeddings/cache_keys.py#L6),
    and both text and image now use the same normalize-aware keying. I also
    added service-side BF16 cache hits that short-circuit before the model
    lane, so repeated requests no longer get throttled behind image
    inference.
    
    **What This Means**
    - Image pressure no longer blocks text, because they are on different
      ports/processes.
    - Repeated text/image requests now return from Redis without consuming
      model capacity.
    - Over-capacity requests are rejected quickly instead of sitting
      blocked.
    - I did not add a load balancer or multi-replica HA, per your GPU
      constraint. I also did not build Grafana/Prometheus dashboards in this
    pass, but `/health` now exposes the metrics needed to wire them.
    
    **Validation**
    - Tests passed: `.venv/bin/python -m pytest -q
      tests/test_embedding_pipeline.py
    tests/test_embedding_service_limits.py` -> `10 passed`
    - Stress test tool updates are in
      [scripts/perf_api_benchmark.py](/data/saas-search/scripts/perf_api_benchmark.py#L155)
    - Fresh benchmark on split text service `6105`: 535 requests / 3s, 100%
      success, `174.56 rps`, avg `88.48 ms`
    - Fresh benchmark on split image service `6108`: 1213 requests / 3s,
      100% success, `403.32 rps`, avg `9.64 ms`
    - Live health after the run showed cache hits and non-zero cache-hit
      latency accounting:
      - text `avg_latency_ms=4.251`
      - image `avg_latency_ms=1.462`

  • 2. 抽象出可复用的 embedding Redis 缓存类(图文共用)
    
    详细:
    1. embedding 缓存改为 BF16 存 Redis(读回恢复 FP32)
    关键行为(按你给的流程落地)
    写入前:FP32 embedding →(normalize_embeddings=True 时)L2 normalize →
    转 BF16 → bytes(2字节/维,大端) → redis.setex
    读取后:redis.get bytes → BF16 → 恢复 FP32(np.float32 向量)
    变更点
    新增 embeddings/bf16.py
    提供 float32_to_bf16 / bf16_to_float32
    encode_embedding_for_redis():FP32 → BF16 → bytes
    decode_embedding_from_redis():bytes → BF16 → FP32
    l2_normalize_fp32():按需归一化
    修改 embeddings/text_encoder.py
    Redis value 从 pickle.dumps(np.ndarray) 改为 BF16 bytes
    缓存 key 改为包含 normalize 标记:{prefix}:{n0|n1}:{query}(避免
    normalize 开关不同却共用缓存)
    修改 tests/test_embedding_pipeline.py
    cache hit 用例改为写入 BF16 bytes,并使用新
    key:embedding:n1:cached-text
    修改 docs/缓存与Redis使用说明.md
    embedding 缓存的 Key/Value 格式更新为 BF16 bytes + n0/n1
    修改 scripts/redis/redis_cache_health_check.py
    embedding pattern 不再硬编码 embedding:*,改为读取
    REDIS_CONFIG["embedding_cache_prefix"]
    value 预览从 pickle 解码改为 BF16 解码后展示 dim/bytes/dtype
    自检
    在激活环境后跑过 BF16 编解码往返 sanity check:bytes
    长度、维度恢复正常;归一化向量读回后范数接近 1(会有 BF16 量化误差)。
    
    2. 抽象出可复用的 embedding Redis 缓存类(图文共用)
    新增
    embeddings/redis_embedding_cache.py:RedisEmbeddingCache
    统一 Redis 初始化(读 REDIS_CONFIG)
    统一 BF16 bytes 编解码(复用 embeddings/bf16.py)
    统一过期策略:写入 setex(expire_time),命中读取后 expire(expire_time)
    滑动过期刷新 TTL
    统一异常/坏数据处理:解码失败或向量非 1D/为空/含 NaN/Inf 会删除该 key
    并当作 miss
    已接入复用
    文本 embeddings/text_encoder.py
    用 self.cache = RedisEmbeddingCache(key_prefix=..., namespace="")
    key 仍是:{prefix}:{query}
    图片 embeddings/image_encoder.py
    用 self.cache = RedisEmbeddingCache(key_prefix=..., namespace="image")
    key 仍是:{prefix}:image:{url_or_path}
