摘要 / Summary

运行时记忆的容量已支持配置，但插件页面没有编辑入口。新增用户画像和工作记忆的容量输入，按字节填写并点击应用，支持放弃修改、范围校验和保存失败重试；默认 4 KiB / 10 KiB 保持不变。

Expose the existing user-profile and working-memory byte limits on Runtime Memory settings, with staged Apply/Discard, integer-range validation and retryable failures. Preserve defaults, exact configured byte values and the separate maintenance-token budget.

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

复用已有 runtimeMemory.userLimitBytes / memoryLimitBytes 配置，接受 1–1048576 的整数字节数。仅写入变更的容量并保留维护预算及未配置项的默认继承。保持原有实时生效语义，不修改持久化、权限、Provider 或模型预算。共享容量常量随浏览器产物打包，边界测试只允许这两个常量，不引入 Source 实现。

Uses the existing configuration and live runtime replacement. No storage migration, authority or Provider change. Lowering below usage does not delete entries: the synthetic fixture retained all eight entries and an identical memories.json hash after increasing and lowering limits. Only the two public Runtime capacity constants may cross the checked client import boundary, and the build bundles them so DSH needs no additional browser module factory.

本地验证 / Local Validation

执行的命令 / Commands run:

pnpm run verify
pnpm run test:root
pnpm run verify:headless
pnpm run verify:package
pnpm run verify:docs
pnpm run release:intent

结果摘要 / Result summary:

All verification phases passed: documentation, typechecks, deterministic build, plugin builds and suites, root tests (2257 passed / 7 conditional skips), Headless activation, package/public-entry checks and release-intent coverage. After adjusting the explicit constant import boundary, reran the root suite, Headless and package checks; reran docs after evidence. The settings suite has 67 passing tests, including 12 new cases for save/discard, busy controls, bounds, exact bytes, preserving inherited/default values, failure/retry, read-only/loading and English copy. Real DSH 0.2.1-rc.2 checks confirm saved values, live capacities, reload persistence, narrow layout and data retention.
