fix(memhub): set the SDK context recall lanes apart

POST /api/v2/context/search passed the caller's `limit` as the normal,
schema and proactive intention top-k alike, so limit=5 ran three full
recall lanes including the intention lane the SDK keeps off by default.
The v2 request now takes `limit` (default 10), `schema_limit` (default
3) and `intention_limit` (default 1) and passes each through. The host
broker's default item cap follows v2's default of 10.

 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
 
-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。
+架构边界以 [`docs/ARCHITECTURE.md`](docs/ARCHITECTURE.md) 为准。
 
-仓库内仍以 One Memory 命名的 Evidence、权限和 Governance 层属于 MemHub 的历史兼容
-模块；产品代码不应绕过这些层直接调用 SDK。本文中的
-原生 SDK 示例主要用于开发、调试和独立验证。
+---
+
+## 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。
+
+生产入口通过共享 Runtime 租约取得公开 `HyMemoryClient`；MemHub 只在调用前执行
+模型配置、密钥和 harness/model 门禁，不维护第二套 memory 正文权威。
+
+来源授权、模型授权和宿主召回授权仍是 MemHub 管理面门禁；memory
+数据平面的权威在 SDK。
 
 ## 当前版本状态

-version:      2.0.3
+version:      见 pyproject / lock（文档数字可能滞后）
 mode:         按运行时配置选择

 ```
 
-仓库 pin、lockfile 和运行时版本守卫均固定到公开的 `hy-memory==2.0.3`。
-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、
-Governance 和撤权边界。
-
 ## MemHub 运行时边界
 
-MemHub 对 SDK 使用以下公开、可复现的本地策略：
+MemHub 通过公开 `HyMemoryClient` 配置使用可复现的本地策略：
 
-- 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。
+- 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**。
 
-发布包固定应用以下 SDK 行为配置：
+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。
