✨ feat(device): add @lobechat/device-identity (stable machine-derived deviceId)

New shared package: `deriveDeviceId` hashes the OS machine id with the userId
(+ salt) so one machine + one user → one stable, user-scoped deviceId that
survives LobeHub reinstalls. Falls back to a caller-supplied random UUID (flagged
via `identitySource: 'fallback'`) when the machine id is unavailable.

Foundational layer — no consumers yet; desktop/CLI wire it up in a later PR.

Part of LOBE-9572. Closes LOBE-9574.

# 🚀 LobeHub Release (20260604)

**Release Date:** June 4, 2026  
**Since v2.2.1:** 88 merged PRs · 11 contributors

> This week brings Execution Devices out of the lab — run agents and
Claude Code on any configured local or remote machine — alongside Claude
Opus 4.8, token-usage analytics, and Page sharing.

---

## ✨ Highlights

- **Execution Devices** — Pick where an agent runs. Desktop and CLI
devices auto-register with a stable machine ID, route through the
gateway by channel, and surface a device switcher in the chat input. Run
remote Claude Code on a configured device, with a recent-directory
picker you can drag to reorder. (#15300, #15315, #15322, #15343, #15351,
#15371)
- **Claude Opus 4.8** — Day-one support for Anthropic's latest model.
(#15314)
- **Token-usage analytics** — A new token-usage mode on the activity
heatmap, backed by a denormalized topic usage/cost rollup so totals stay
accurate without recomputing from messages. (#15365, #15417, #15425)
- **Page sharing** — Share a Page through a dedicated document share
flow, plus new Workspace and Agent share tables. (#15309, #15439)
- **Self-iteration agents** — Agent Signal's execAgent migration lands a
server-runtime bridge, async memory writer, and a registered
self-iteration tool package, with a CLI trigger command for testing.
(#15360, #15364, #15392)
- **Knowledge search** — BM25 search now extends to file-backed
documents, and the portal ships an editable CodeMirror viewer for local
files with document highlighting. (#15247, #15298)

---

## 🏗️ Core Agent & Architecture

### Agent Signal & Runtime

- **execAgent migration** — Server-runtime bridge, completion
projection, async memory writer, and removal of the legacy
`executeSelfIteration` path. (#15392)
- Registered the self-iteration builtin tool package and restored the
three mode-specific self-iteration agent slugs. (#15202, #15364)
- Added a CLI trigger command with a golden-snapshot fixture for Agent
Signal. (#15360)
- **Skill priority** — Agent Builder now emits a skill-priority
instruction with matching server runtime. (#15409)
- Retry empty LLM completions instead of silently finishing the turn.
(#15355)
- Classify topic/agent/session foreign-key violations as
`ConversationParentMissing` for clearer recovery. (#15408)
- Persist canonical nested usage/performance on assistant messages, and
re-link orphan tool messages at the raw bucket write boundary. (#15359,
#15438)
- Guard `createAgent` against LLM double-encoded array fields. (#15381)

---

## 🖥️ Execution Devices & Gateway

- Auto-register desktop and CLI devices with a stable machine ID, and
add the `@lobechat/device-identity` package. (#15300, #15321)
- New Devices settings page behind the Execution Device Switcher lab,
with a device switcher shown for all agents in the chat input. (#15315,
#15371)
- `connectionId` + channel routing across the gateway client and device
list; preset the local device on the first LLM request for the 本机
target. (#15322, #15435)
- Run remote Claude Code on a configured device, with drag-to-reorder
recent-directory management and client renders for device tool results.
(#15343, #15351, #15437)
- Preserve content and state across gateway tool calls, and prevent
duplicate streaming from stale reconnects. (#15114, #15354)

---

## 🖥️ CLI & Desktop

- Preserve content/state for connect local file and shell tools; render
the `runCommand` tool result card. (#15441, #15442)
- New `lh topic view` command; CLI now auto-registers its device on
login, matching desktop. (#15340, #15377)
- Resolve CLI tools from the shell `PATH`, and clarify local command
session handling. (#15368, #15389)
- Relocate visual-ref helpers to `@lobechat/const` to fix a renderer
crash; upload `.blockmap` files to S3 for differential updates. (#15326,
#15369)
- Fix a market OAuth expiry that triggered the wrong re-login modal, and
kill dev child processes on parent shutdown. (#15246, #15290)

---

## 🗂️ Pages, Library & Knowledge

- Document share flow with business slot stubs, plus Workspace and Agent
share tables. (#15309, #15439)
- Export Agent profiles as Markdown, preserving an empty agent prompt on
export. (#15312, #15316)
- Editable CodeMirror viewer for local files with document highlighting;
BM25 search extended to file-backed documents. (#15247, #15298)
- Default new Agent-doc files to `.md` and preserve IME composition;
refresh folder data on slug switch and dedupe breadcrumb fetches.
(#15335, #15427)

---

## 💬 Chat & User Experience

- Group-by-status mode for the Topic sidebar; dropped the legacy
session→agentId compatibility path from Topic queries. (#15366, #15378)
- Restore editor focus after the file picker closes, and close the skill
dropdown before navigating to settings. (#15391, #15394)
- Strip markdown tokens from fallback Topic titles; keep an open
ActionBar popup when hovering another message. (#15303, #15372)
- Stabilize home starter loading and stop transliterating model names in
the home starter; show artifact source while streaming. (#15310, #15324,
#15386)
- Group the sidebar spacer with recents and agents. (#15373)

---

## 📊 Analytics, Tasks & Notifications

- Token-usage mode on the activity heatmap, backed by a denormalized
topic usage/cost rollup. (#15365, #15417, #15425)
- Push: new `PushChannel`, receipt cron, and `pushToken` tRPC API.
(#15233)
- Tasks now support file and image attachments. (#15141)

---

## 🧩 Models & Providers

- Support Claude Opus 4.8 and configurable model routing with starters.
(#15314, #15384)
- MiniMax M3: new model entry and an Anthropic video runtime. (#15380,
#15403)
- Add `intern-s2-preview` with `thinking_mode`, and `step-3.7-flash`
support. (#15308, #15317)
- Block disabling the official provider; fix default provider setup in
business mode. (#15379, #15382)

---

## 🎨 UI & Modals

- Migrate modals to `@lobehub/ui/base-ui` (LOBE-9711 + eval batch),
including the create-custom-model and feedback/changelog modals.
(#15401, #15416)
- Restructure confirmModal title and content across deletion flows;
polish the service-model form and migrate its Switch to base-ui.
(#15426, #15440)
