 ### Added
 
+- #574：新增工作区级 Markdown 笔记库、跨岗位引用、会话结论沉淀与实际上下文出处；支持中文路径、全文搜索、授权图片附件、手动 Mem 双向同步、冲突副本和基于版本校验的历史恢复。
+
 - 项目任务新增持久化人工验收：逐项核对验收标准，绑定原会话、执行和产出摘要版本；接受后任务完成，拒绝保留原因并回到待验收。验收与任务状态原子保存，过期计划和产出拒绝裁决，网络重试保留幂等记录。
 - 文档支持目录树及键盘导航，会话记忆准确继续原会话；关系图默认提供员工、来源、资源与证据的逐步浏览。
 - #549：按已确认设计更新收件箱审批工作台，提供请求列表、风险与岗位筛选、裁决操作、执行证据与异常详情、可追溯审计和运行时间线；断线保留只读快照，不确定的审批重试先核验权限，如实展示未观测用量和实际预算比例。

+## Source and local evidence
+
+The publishing worktree starts from `bb4d11e` on `origin/main`. The existing
+resource navigation, drive browser, image preview and newer goal/date changes
+are retained. No personal maintenance tool, credential, deployed database,
+backup, host path or runtime artifact is part of this patch.
+
+| Check | Evidence |
+| --- | --- |
+| Shared/server compilation | PASS in the publishing worktree |
+| Renderer type check | PASS in the publishing worktree |
+| Vault/editor and App targeted regressions | PASS: 92 tests in the publishing worktree |
+| Backend/context/drive/turn targeted regressions | PASS: 107 tests; Windows symlink-privilege case explicitly skipped |
+| Archive/index recovery fault tests | PASS; injected index persistence failure preserves identity, binding and content; independent source review passed |
+| Notebook usage receipts | PASS: actual injected references, versions and redacted excerpts; position mismatch and missing boot auth rejected |
+| Scope and source scan | PASS: no local maintenance path, username, secret or live-test Vault identity in release scope |
+| Diff checks | PASS |
+| Full POSIX suite and packaging matrix | NOT VERIFIED locally; required GitHub checks remain authoritative |
+
+Windows broad backend runs expose pre-existing CLI/symlink/CRLF platform
+assumptions. Those failures are not represented as a green full-suite result.
+The CI matrix runs the complete suite on Linux/macOS and the existing dedicated
+Windows staging/WSL acceptance jobs.
+
+## Local integration evidence
+
+The earlier source implementation was exercised against an additive local Mem
+Vault API deployment using two independent client workspaces and existing
+workspace-scoped read/write credentials. No model was required.
+
+- PASS: independent blank note IDs, write/pull, concurrent text edits retained
+  as two versions, stale local/remote revision rejection and version restore.
+- PASS: original PNG transfer and preview SHA-256 round trip.
+- PASS: single-client and concurrent image edits retain old/new original blobs
+  and resolve to independently previewable version paths.
+- PASS: failed old-image restoration, later external image edits and retry
+  behavior preserve edited bytes.
+- PASS: case/NFC aliases with different originals fail before rewrite/upload.
+- PASS: lost commit response replay, long Unicode conflict paths, path-owner
+  protection and asset-link relocation when conflict copies change directory.
+
+This is local source/runtime evidence, not a claim that the publishing commit
+has already passed GitHub checks or that a new installer has been released.
+
+## Review and merge
+
+Independent source review found and closed the archive/index failure and
+synchronization-edge defects. Public CI, conversation resolution and any
+required GitHub approval must complete on the final pushed commit before merge.

+# Workspace notebook and Mem synchronization
+
+RoleWeave stores editable notebook bodies as ordinary UTF-8 Markdown files in
+`notes/` under the opened workspace. A note can exist without a position. The
+Notes and Drive surfaces are the default resource workflow; the external Doc
+connection and position-document APIs remain compatible but are not a second
+required notebook.
+
+## Notes and context
+
+Create folders or notes with Unicode names, search titles and body text, and
+link notes using ordinary Markdown or wikilinks. Reading, live editing and
+source modes share the existing editor and autosave state. Raster images are
+loaded through the authorized notebook bridge rather than remote image URLs.
+Use reading mode for image previews; the live editor does not fetch arbitrary
+image addresses.
+
+Associate existing note identities with positions. Association controls
+automatic notebook context selection; it is not a new filesystem sandbox for
+host tools. Each turn receives only active associated notes, at most four
+bounded excerpts with a combined 32 KiB JSON context budget. Notes remain
+untrusted data and do not grant tools or override runtime instructions.
+The conversation exposes the references, versions and excerpts actually
+assembled for a turn. Completed public answers can be reviewed and saved as a
+note with their original position/session/turn provenance.
+
+Markdown bodies remain on disk. `.roleweave/vault/` contains identities,
+association metadata, recovery journals, bounded prior versions, attachment
+metadata and immutable turn-use receipts. Local history is limited to 32
+versions per note and 64 MiB per workspace; reads return at most 20 versions
+and 8 MiB. Restore uses the latest content hash and refuses stale writes.
+
+Existing `knowledge/` files are referenced in place and are initially read-only
+in the notebook. Explicit migration moves one file into `notes/` and preserves
+the old reference alias. Position package configuration, tools and permissions
+remain separate from notebook prose.
+
+## Files and synchronization
+
+Insert an original file from the configured Mem workspace, or use ordinary
+local attachments under `notes/assets/`. Supported raster previews are PNG,
+JPEG, WebP and GIF, capped at 8 MiB. Original attachment transfer is capped at
+32 MiB per object and validates size and SHA-256. Credentials stay in the
+desktop/server connection; they are never sent to the renderer.
+
+Synchronization is manual and bidirectional. Both devices need a RoleWeave
+client connected to the same authorized Mem service and workspace. Select the
+same named remote Vault on the second client and synchronize to pull its notes.
+Local autosave does not imply a completed remote synchronization. Unsaved
+drafts and in-flight editor writes block synchronization.
+
+Mem's Vault API provides independent logical note identities, immutable
+revision history, tombstones and whole-Vault compare-and-swap commits. It is
+separate from blob deduplication, so two empty notes remain independent. A
+local content hash protects apply against external edits. Concurrent edits
+produce explicit conflict copies; deterministic copy identities and durable
+pre-image state prevent retries from duplicating committed copies.
+
+Images use content-version paths such as `assets/<sha256>.png`, keeping their
+original bytes and relative Markdown/Wiki references. Concurrent image versions
+can coexist; prior notes and history still reference their original images.
+Case/NFC aliases resolving to different originals are rejected before changes.
+
+Limits: 1 MiB per note, 16 MiB active notebook text, 1,000 logical heads, 512
+changed entries and 4 MiB wire payload per remote commit. A failed or limited
+operation is reported; the client does not silently truncate notes.
+
+## Product boundaries
+
+This is a portable notebook foundation, not an Obsidian plugin host or realtime
+collaborative rich-text editor. Obsidian can read and edit the same Markdown and
+relative attachment files. The remote Mem endpoint must be reachable from both
+devices; this change does not expose a local-only service publicly or add
+hosted signup/SSO. It uses the canonical Mem Vault API introduced by
+bytefolk/mem#234. Existing Mem bundle v2 export does not include Vault history;
+the dedicated Vault snapshot contract owns notebook transfer.
+
+Refs #574 and #511.

Metadata conflicts still run on every platform; exclusive creation bounds only the distinct-file fixture, and native/hard-link aliases verify one upload and unchanged originals.

All five now use a bounded descriptor with no-follow/nonblocking flags where available, regular-path checks, size limits and before/after identity checks. Snapshot requests use known routes and reconstructed UUIDs; poisoned state cannot create a request.
