摘要 / Summary

Record fresh verification that #225 and #230 are already fixed in v0.5.7. The report reproduces the legacy migration failure before the existing copy repair, verifies resumed history after cold restart, and checks the current composed WebUI with the real Mnemon CLI. No product source or release artifact changes.

关联 Issue 或背景 / Related Issue or Context

Closes #225. Closes #230. Both implementation fixes were merged in #226 and released by #228; this maintainer-authorized evidence update records current-main results without creating a redundant patch.

仓库规范检查 / Repository Rules

• 未修改 DSH 官方源码，未让 tsconfig 指向 DSH 源码 checkout，仅使用正式的 @deepseek-ai/* NPM 契约。 / I did not modify DSH source or point tsconfig at a DSH source checkout, and used only published @deepseek-ai/* NPM contracts.
• Client 与 Host 边界仍以浏览器安全的 src/host/protocol.ts 为准，没有在两侧重复定义 wire DTO。 / The Client and Host boundary still uses browser-safe src/host/protocol.ts as the source for wire DTOs.
• 持久化格式、RPC 权限、路径或凭据处理的变更包含兼容或拒绝路径、安全分析和相应测试。 / Changes to persistence formats, RPC authority, paths, or credentials include compatibility or rejection paths, security analysis, and tests.
• 没有提交 token、密钥、私有记忆、未脱敏日志或生成的 lib/ 文件。 / I did not commit tokens, credentials, private memory, unredacted logs, or generated lib/ files.
• 用户可见文案和长期文档已同步维护中文与英文版本，命令、配置键和路径保持一致。 / User-facing copy and long-lived documentation are synchronized in Chinese and English, with matching commands, configuration keys, and paths.
• 会改变发布制品或其元数据的 PR 已添加 changeset；仅测试、CI 或站点文档变更可不添加。 / A PR that changes a published artifact or its metadata includes a changeset; test-only, CI-only, and site-documentation-only changes may omit one.
• 新增和修改的代码、注释、文档、提交信息不含 emoji。 / New and modified code, comments, documentation, and commits contain no emoji.

兼容性与数据安全 / Compatibility and Data Safety

Documentation-only: no persistence format, RPC permission, configuration, package metadata, or runtime behavior changes; no changeset is required. Every operation used disposable DSH/Mnemon roots and synthetic conversation/memory content. The copy repair preserved the original SHA-256 and changed only two invalid summary fields. No credentials, raw private logs, or generated lib files are included.

本地验证 / Local Validation

执行的命令 / Commands run:

pnpm install --frozen-lockfile; pnpm exec vitest run tests/legacy-session-repair.spec.ts tests/lifecycle.spec.ts tests/dsh-connection-compat.spec.ts; MNEMON_NATIVE_TEST_CLI=/opt/homebrew/bin/mnemon pnpm --filter dsh-mnemon-source-memory-spaces test -- tests/native-integration.spec.ts; both default and --strategy-extensions real WebUI harnesses; pnpm run verify:docs; git diff --check.

pnpm run verify

结果摘要 / Result summary:

Full pnpm verify: 1,249 passed, 7 opt-in skips, with types, deterministic builds, package checks and real Headless restart/disable checks passing. Targeted migration/lifecycle/connection: 58 passed. Real Native Source run: 169 passed including CLI create/write/recall/forget, 1 Windows skip. Real WebUI: strict legacy failure -> copy repair -> two turns -> cold reopen; Native create/activate/keyword recall/restart/content/soft-delete. Authenticated status RPC 200, healthy=true, commandFound=true; unauthenticated 401. No Windows, Electron, live external Provider, or model-quality retest. The original 0.5.5/missing-CLI environment was not recreated; its historical 405 evidence remains explicitly linked to #226. Standalone packed-artifact tests were not repeated for this docs-only addition.
