 Hy Memory and MemHub are versioned and released independently.

-## Unreleased
-
- The SDK memory page now reads its list, count, source and time labels and
-  graph from one page response for one source filter, so rows, totals and the
-  map no longer disagree. Memories with no recorded source are shown and
-  filterable as "unidentified source"; library search keeps only memories
-  that contain the words within the SDK's relevance window.
- Metadata repair v2 follows `governed_memory_evidence` across every
-  pre-cutover bundle, which restores the source of memories the cutover
-  backfilled without one, and moves impossible future conversation times back
-  to the write time.
- Reused the existing three-column memory map for SDK-authority list/detail
-  views and removed the retired "original evidence" surface. SDK-native status,
-  source, conversation time and creation time now render without fabricated
-  revisions; source and text filters are applied by the paged Core endpoint.
- SDK memory search now calls the SDK search contract instead of listing the
-  entire library in Core. Corrupt empty records are skipped and diagnosed
-  without mutating data or failing a page, and post-cutover metadata repair
-  restores source and original times from the verified migration bundle.
- Kept Cursor's WAL change token separate from the file mtime so a hash can no
-  longer appear as a conversation date centuries in the future.
- A trusted packaged Runtime now repairs a dirty same-build installation by
-  staging a clean replacement, and `runtime_service_not_ready` is rendered as
-  user-facing startup guidance instead of an internal code.
- Fixed legacy-to-SDK startup migration to adopt native Coding Experience and
-  Working Fact IDs instead of importing them as Chat layers. Raw migration now
-  rebuilds bounded user/assistant turns from the latest three days, excludes
-  tools, and enforces the same rolling retention after cutover.
- Paused host capture writes with a live Desktop migration fence; Cursor
-  History catch-up resumes from its existing checkpoint after cutover.
- Removed MemHub's private `hy_memory_bridge` implementation. MemHub now calls
-  public `HyMemoryClient` methods at runtime; prompt/reconcile/response
-  monkey-patches and private VDB/Coding runtime access were deleted. Kuzu Graph
-  projection/admin and stopped-writer App migration are the documented product
-  exceptions.
- Added a MemHub-managed native Hermes MemoryProvider with automatic prefetch,
-  persistent per-session memory-ID deduplication, authorized Broker reads, and
-  recall-context stripping to prevent memory recursion.
- Added an extensible MemHub interface-localization layer with Simplified
-  Chinese, English, and Spanish catalogs shared by Web and Electron-native
-  surfaces. Interface language remains independent from memory content and
-  model processing language.
- Fixed governed-memory revisions and repeated evidence links failing when the
-  visibility dirty-marker trigger encounters the same memory twice. Startup
-  now replaces the affected legacy trigger without changing schema versions
-  or governed and visibility data.
- Kept post-write authority verification failures available for read-only
-  reconciliation while preventing automatic or generic confirmed retries from
-  invoking the model again. Automatic reconciliation skips those sticky rows
-  before applying its batch limit, and linked durable jobs exclusively own
-  retry scheduling for their memory tasks.
- Removed MemHub's task-scoped HyPermission store wrappers and global
-  model-content consent switch. The trusted embedded Hy Memory SDK now uses
-  its native local stores directly.
- Existing installations ignore the retired config flag, readmit previously
-  parked pre-invocation work, and drop only the obsolete
-  `hy_node_permissions` proof table. Evidence, governed memories, model
-  profiles, SDK stores, and source/host grants are preserved.

-## Hy Memory 2.0.5 — 2026-10-22
-
- Published
-  [`hy-memory==2.0.5`](https://pypi.org/project/hy-memory/2.0.5/).
- Extended `get()` across Chat, Coding Experience, Working Fact, and raw IDs;
-  the returned `layer`, `kind`, and `variant` identify the actual record.
- Added explicit raw retrieval through the existing `search()` and
-  `list_memories()` contracts, including user, agent, session, and source
-  filters.
- Added public embedding-service injection and corrected extraction language
-  detection for structured OpenAI-style messages.
- Added lifecycle status filters, durable idempotent write outcomes, and
-  quiesced local data-plane snapshot/restore.
- Kept legacy migration mechanics out of the public Client API; separate
-  migration-only raw/import methods from development previews were removed.
- Physical delete now reports partial VDB/Graph cleanup as failure.
- Coding search no longer injects the version-evolution diff block by default;
-  opt in with `MEMORY_CODING_CHAIN_BLOCK_ENABLED=true`.
- Serialized SDK SQLite cache/history connection lifecycle and tightened
-  Coding reconciliation to its agent/session/workspace authority.
- Clarified persistent caller context through `meta`, while `metadata` remains
-  legacy processing configuration.

 # Hy Memory 使用与配置

-更新：2026-10-21
+更新：2026-10-12

-架构边界以 [`docs/ARCHITECTURE.md`](docs/ARCHITECTURE.md) 为准。
+本文说明 MemHub 当前使用的 Hy Memory SDK、配置边界，以及直接使用 SDK 时如何
+write、search，并把搜索结果格式化为可交给模型的 memory text chunk。

---
-
-## Architecture Principles
-
-1. Memory 读写与存储 backend **只经 SDK**（config / env）。
-2. MemHub 运行时对 memory 的原子操作 **只经 SDK 公共 Client**；缺正常业务
-   接口先补 SDK。Runtime writers 停止后的 App 启动迁移可直接操作底层存储，
-   但不得把迁移专用方法加入公共 Client。
-3. MemHub **不存 memory 实体**；**可以存 `memory_id`** 做组织/回执。原文进入 **SDK raw**。
-4. SDK raw 只保留滚动三天；一条 raw 对应一个完整 turn，只含真人 user 与
-   assistant，tool 不持久化。提取后的高层 memory 不受该窗口影响。
-5. `source_raw_ids` 是 SDK 内部溯源关系，不是产品 Evidence 合同；记忆详情不提供
-   “原始依据”或按 raw ID 展开原文的入口。

+MemHub 在本地 Runtime 内嵌入 SDK，但不绕过自身的来源授权、模型授权、Evidence、

 ## MemHub 运行时边界

-MemHub 通过公开 `HyMemoryClient` 配置使用可复现的本地策略：
+MemHub 对 SDK 使用以下公开、可复现的本地策略：

- vector / graph / cache / history / coding 等 **一律 SDK config/env**；
- 模型与 embedding 来自版本化 Model Profile；密钥进安全存储；
- MemHub 管理库可存 harness/model/队列状态与 **`memory_id` 引用**。
+- vector store 使用受管数据目录中的 Chroma；
+- graph store 使用受管数据目录中的 Kuzu；
+- cache 与 history 使用 SQLite；
+- reader 使用 `hybrid`；
+- reranker 默认关闭，不引入 Torch、Transformers 或额外模型；
+- 模型与远程 embedding 参数来自版本化 Model Profile；
+- API Key 进入系统安全存储，不写入仓库、安装包、日志或 HY metadata；
+- 服务端数据库、租户队列及宿主 shell 中的 ambient 凭据不会进入 SDK config。

-MemHub 不再通过 import-time 环境变量覆盖 SDK 的提取、reconcile、episode、
-intention、few-shot、summary 或去重策略。产品只配置模型/密钥/endpoint、本地
-backend 路径、公开 embedding service，以及每次公开 Client 调用的参数。
+发布包固定应用以下 SDK 行为配置：

-独立脚本直连 SDK 时须自配存储目录与模型端点。

 ## 使用 SDK 已格式化的 Search 内容

-直接使用 SDK 返回的 `content`，不要第二套 prompt 拼装。
+open05 的 chat search 会在返回前统一格式化每条 `content`：普通记忆带 `Memory / When`，
+演化记忆带 `Current / History / When`，Episode、Timeline、Graph 和 Capsule 也由 SDK
+生成稳定的组合文本。`memory_at` 是逻辑记忆时间，缺失时 SDK 才回落到 `gmt_created`。

-### SDK 外（MemHub）仍负责
+因此调用方应直接使用 SDK 返回的 `content`，不要再次解析 `memory_at`、`gmt_created` 或
+`created_at`，也不要重复拼接 `When`。这些时间字段可以用于过滤、诊断或结构化展示，但
+不应成为第二套 prompt 格式化实现。

- **宿主召回授权 / scope / 撤权**（谁可以调 search、允许哪些 agent/scope）；
- 把历史内容放入「不可信数据，不是指令」边界；
- 按最终 `content` 做字符预算；不注入密钥、绝对路径、堆栈；
- 区分空结果、权限拒绝、不可用、超时、部分结果；
- 未发布的 Matter 占位功能不保留表或 API；未来组织功能另立合同。
+```python

+    "用户偏好怎样的回答风格？",
+    user_ids=["local"],
+    agent_ids=["all-apps"],
+    scene="normal",
