 - 仓库现在同时补齐了 `pnpm-workspace.yaml` 和根 `package.json` 的 `packageManager`，将 `pnpm` 作为桌面开发与打包的规范入口。
 - 仓库通过 `.npmrc` 固定安装 devDependencies，避免宿主机的 `NODE_ENV=production` 破坏桌面构建链路。
 - `cargo test -p redis-core` 默认验证共享后端核心，包括 mock Redis 握手与命令执行测试，避免在缺少桌面系统库时阻断后端迭代。
+- `pnpm --filter @redis-gui/desktop test` 运行桌面前端的最小单测基线；当前覆盖共享错误映射层，避免后续功能迭代把后端错误码重新退回成零散文案拼接。
 - `pnpm run desktop:dev` 启动浏览器态工作台壳层，用于检查布局、交互和 demo fallback；此模式下没有 Tauri 命令桥。
 - `pnpm run desktop:tauri:dev` 启动带 Tauri 后端桥的桌面工作台；连接测试和命令执行会调用现有 `test_redis_connection` 与 `execute_redis_command` 命令，因此需要完整的 Tauri Linux 运行依赖。
 - `pnpm run desktop:tauri:build` 会先执行桌面前端 build，再进入 Tauri/Rust 的真实打包流程；当前 Linux `.deb` 与 `.rpm` 产物位于仓库根 `target/release/bundle/`。

 - 首版可见界面现在已接入真实的桌面 browse / inspect / string save / TTL update 路径，但仍保持危险操作和完整产品化流程在后续阶段演进。
 - 当前前端消费 `backend_bootstrap`、`test_redis_connection`、`browse_redis_keys`、`read_redis_value`、`write_redis_value` 和 `execute_redis_command`；浏览器态仍保持明确的 demo fallback。
+- 当前前端还通过共享错误映射层统一消费 `redis-core` 的稳定错误码，使连接测试、浏览、读取、保存、TTL 和命令执行失败都落到一致的操作提示上。
 - `inspect_redis_key` 与 `update_redis_key_ttl` 已在桌面桥可用；当前 UI 已暴露 TTL 设置与移除控制，但删除执行仍保持未开放状态。
+- inspector 现在对 `hash/list/set/zset/stream` 提供结构化只读面板，不再要求操作者从原始 JSON 文本中手动解析 typed value。
 - 连接测试、key browse、value inspector 和命令托盘在 Tauri 桌面运行时走真实后端桥；浏览器态 `pnpm run desktop:dev` 会明确回退到 demo 数据，不伪装成真实 Redis 行为。

+# HAC-17 Frontend Foundation Hardening
+
+Date: 2026-03-28
+Owner: Senior Frontend Engineer
+Issue: HAC-17
+
+## Goal
+
+Harden the desktop frontend foundation for upcoming iterations without changing backend contracts or expanding product scope.
+
+## Selected Scope
+
+- extract a shared frontend error mapping layer that translates stable backend error codes into consistent operator-facing copy
+- route connection test, key browse, value read, string save, TTL update, inspector refresh, and command execution failures through the shared mapper
+- add the minimum test baseline around the new error translation logic so future feature work can extend it safely
+- update shared run and acceptance docs so QA can verify the new error behavior
+
+## Non-Goals
+
+- no backend contract change
+- no new Redis capability surface
+- no visual redesign outside the existing desktop shell language
+- no delete execution or broader write support
+
+## Verification Plan
+
+- `pnpm --filter @redis-gui/desktop test`
+- `pnpm run desktop:build`
+
+## Notes
+
+- The existing shell already exposes stable backend error codes from `redis-core`; the current gap is inconsistent UI handling rather than missing backend semantics.

+# HAC-18 Typed Inspector Panels
+
+Date: 2026-03-28 UTC
+Owner: Senior Frontend Engineer
+Issue: HAC-18
+
+## Goal
+
+Ship one more visible desktop feature slice without waiting on GUI screenshot capture or AppImage validation.
+
+## Selected Scope
+
+- upgrade the inspector for non-string Redis values from raw JSON text to structured read-only panels
+- keep the existing string edit flow, TTL actions, and error notice foundation unchanged
+- stay within the current `read_redis_value` contract and avoid backend expansion
+- add minimum frontend tests around the new structured presentation mapping
+
+## Non-Goals
+
+- no delete execution
+- no backend contract changes
+- no packaging or screenshot evidence work in this heartbeat
+- no full redesign of the existing desktop shell
+
+## Verification Plan
+
+- `pnpm --filter @redis-gui/desktop test`
+- `pnpm run desktop:build`
+
+## Expected User Impact
+
+- operators can scan `hash/list/set/zset/stream` payloads directly in the inspector without mentally parsing raw JSON
+- the read-only boundary for non-string types remains explicit, but the viewing experience becomes materially more usable

+# HAC-22 DB Switcher Hardening
+
+Date: 2026-03-31 UTC
+Owner: Senior Frontend Engineer
+Issue: HAC-22
+Scope: `desktop-v1` user-visible frontend hardening only
+
+## Context
+
+- `apps/desktop` already ships a visible DB switcher, but the current UI only renders four fixed choices: `db0`, `db1`, `db2`, and `db5`.
+- Current product scope already includes one active standalone Redis connection, explicit DB context, and DB-scoped browse / inspect / command flows.
+- The hardcoded four-item list is weaker than the current product boundary and makes shell-level verification less representative for operators who need to move across common DB indexes.
+
+## Decision
+
+- Do not expand product scope or alter backend contracts.
+- Keep the existing rail placement and interaction model for the DB switcher.
+- Widen the visible DB switcher to a predictable default operator range and ensure the currently active DB remains selectable even when it falls outside the default range.
+
+## Implemented Slice
+
+1. Added a shared frontend helper that returns DB labels for the switcher.
+2. Defaulted the visible range to `db0` through `db15`.
+3. Preserved the currently active DB when it falls outside that range and kept the options numerically ordered.
+4. Covered the helper with focused Vitest cases.
+
+## Acceptance
+
+- The visible DB switcher no longer depends on a four-item hardcoded list.
+- Operators can select common DB indexes from `db0` through `db15` without editing connection drafts.
+- An active DB outside the default range still appears in the switcher and stays selectable.
+- `pnpm --filter @redis-gui/desktop test` and `pnpm run desktop:build` remain green.

+# HAC-26 Workspace State Foundation
+
+Date: 2026-03-31 UTC
+Owner: Senior Frontend Engineer
+Issue: HAC-26
+Scope: `apps/desktop` frontend foundation only
+
+## Context
+
+- `apps/desktop/src/App.tsx` already owns the visible desktop-v1 shell, but it still contains repeated inline logic for key filtering, selected-key fallback, live key replacement, and paged append handling.
+- These state transitions are part of the browsing and inspector foundation, not one-off UI copy, and upcoming desktop-v1 slices will need them again.
+- The PM comment on `HAC-26` asked for the highest reusable foundation return, not a new visible feature.
+
+## Decision
+
+- Do not expand product scope.
+- Extract reusable key-workspace state helpers from `App.tsx` into `src/lib`.
+- Cover the extracted state transitions with focused Vitest cases so future desktop-v1 changes can reuse the same behavior safely.
+
+## Planned Implementation
+
+1. Create a shared frontend utility for:
+   - filtering visible keys by search text
+   - resolving selected key fallback when visible results change
+   - replacing a key record after live metadata/value refresh
+   - appending paged browse results without duplicate rows
+2. Update `App.tsx` to consume the shared utility instead of inline logic.
+3. Add Vitest coverage for zero-result fallback, selection resolution, replacement merge behavior, and append deduplication.
+4. Re-run `pnpm --filter @redis-gui/desktop test` and `pnpm run desktop:build`.
+
+## Acceptance
+
+- `App.tsx` no longer owns the reusable key-workspace list and selection transitions inline.
+- The extracted helper is covered by focused tests.
+- Existing desktop frontend tests and production build remain green.
+- No backend contract or visible feature scope changes are introduced.
