 ## Status
 
-Latest published scaffold release: `v0.3.0 - Registry v1 and Simplified Chinese Revision`.
+Latest published scaffold release: `v0.3.1 - Registry Guidance Cleanup`.
 
-This revision includes:
+This patch release:
 
-* portable acquisition and bootstrap,
-* traceable multi-session coordination,
-* visitor/session identity and message routing,
-* human review, provenance, and tag hygiene,
-* bounded workflow routes.
+* removes stale live guidance that still allowed manual CSV registry edits,
+* marks the localization source-drift note and pre-v1 registry audit as historical provenance,
+* leaves Registry Contract v1, schemas, runtime paths, machine fields, statuses, localization protocol, and generated views unchanged.
+
+`v0.3.0 - Registry v1 and Simplified Chinese Revision` remains the feature baseline beneath this patch.
 
 CapstanAI may later grow a richer deterministic layer, along with relay, vault, and protocol modules. LabNote begins as the simplest useful ledger.

+# 2026-09-03 Revision: Registry Guidance Cleanup
+
+## English
+
+### Release
+
+`v0.3.1 - Registry Guidance Cleanup`
+
+This patch release removes stale registry guidance left behind after Registry Contract v1 became the canonical model.
+
+### What Changed
+
+- `lobby/README.md` no longer permits manual CSV registry edits on operator request.
+- `examples/example_message_packet.md` now reflects the generated, read-only compatibility-view rule.
+- `docs/localization/COMMUNICATION_REGISTRY_SOURCE_DRIFT.md` is preserved as historical provenance while explicitly recording that Registry Contract v1 superseded its earlier CSV-edit exception.
+- `docs/registry/REGISTRY_SURFACE_AUDIT.md` is labelled as a historical pre-v1 audit rather than a current defect list.
+
+### What Did Not Change
+
+This release does not change:
+
+- Registry Contract v1;
+- schemas or validators;
+- runtime paths;
+- JSON keys or machine fields;
+- lifecycle states or status values;
+- generated registry views;
+- localization protocol or language routing;
+- permissions, Git behaviour, or write targets.
+
+### Compatibility
+
+`v0.3.1` is a patch-level documentation consistency release on top of `v0.3.0 - Registry v1 and Simplified Chinese Revision`.
+
+English remains the canonical protocol language. The Simplified-Chinese route remains supported and protocol-invariant.
+
+### Validation
+
+The corrective PR head passed the repository's `Registry validation` GitHub Actions workflow before merge.
+
+The release tag must point to the exact audited `main` commit produced by the v0.3.1 release-prep merge.
+
+### Historical Preservation
+
+Historical audit text and archived legacy guidance remain preserved where they are explicitly historical. This patch corrects active guidance without rewriting the project's provenance trail.

+## 简体中文
+
+### 版本
+
+`v0.3.1 - Registry Guidance Cleanup`
+
+这个补丁版本用于清理 Registry Contract v1 成为基准模型后仍残留在发布表面的过时登记库指导。
+
+### 变更内容
+
+- `lobby/README.md` 不再保留“操作者明确要求时可手工编辑 CSV 登记视图”的旧例外。
+- `examples/example_message_packet.md` 现已与当前规则一致：CSV 登记视图属于生成的只读兼容视图。
+- `docs/localization/COMMUNICATION_REGISTRY_SOURCE_DRIFT.md` 继续作为历史溯源记录保留，同时明确说明 Registry Contract v1 后来取代了早期允许手工编辑 CSV 的例外。
+- `docs/registry/REGISTRY_SURFACE_AUDIT.md` 现已明确标记为 v1 之前的历史审计，而不是当前缺陷清单。
+
+### 未发生变化的部分
+
+本版本不改变：
+
+- Registry Contract v1；
+- schema 或验证器；
+- 运行时路径；
+- JSON 键或机器字段；
+- 生命周期状态或状态值；
+- 生成的登记视图；
+- 本地化协议或语言路由；
+- 权限、Git 行为或写入目标。
+
+### 兼容性
+
+`v0.3.1` 是建立在 `v0.3.0 - Registry v1 and Simplified Chinese Revision` 之上的补丁级文档一致性版本。
+
+英语仍是基准协议语言。简体中文路线继续受到支持，并保持协议不变性。
+
+### 验证
+
+纠正 PR 的审阅头提交在合并前已通过仓库的 `Registry validation` GitHub Actions 工作流。
+
+发布标签必须指向 v0.3.1 发布准备 PR 合并后经过核验的准确 `main` 提交。
+
+### 历史保留
+
+凡是明确属于历史内容的旧审计文本和归档旧指导都会继续保留。本补丁修正当前有效指导，但不会改写项目的溯源历史。

-此修订包括：
+这个补丁版本：
 
-* 可移植的获取与初始化流程，
-* 可追踪的多会话协调，
-* 访客会话身份与消息路由，
-* 人工审阅、溯源信息和标签卫生，
-* 有明确边界的工作流路径。
+* 清理仍允许手工编辑 CSV 登记视图的过时当前指导；
+* 将本地化来源漂移说明和 v1 之前的登记库审计明确标记为历史溯源材料；
+* 不改变 Registry Contract v1、schema、运行时路径、机器字段、状态值、本地化协议或生成的登记视图。
