* ✨ feat(portal): editable CodeMirror viewer for LocalFile + Document highlight

Replace the read-only Highlighter in the LocalFile portal preview and the
Document portal highlight mode with a shared `CodeEditorPane` powered by
`@lobehub/editor/codemirror`. Pane supports inline editing, Cmd/Ctrl+S to
save, lobeTheme tokens, and language-aware syntax highlighting.

LocalFile flow
- Track per-path edit buffers + save action in the chat portal store
  (`dirtyLocalFileContents`, `setLocalFileBuffer`, `saveLocalFile`).
- Show a filled dot on the tab close button when the file is dirty;
  hovering still reveals the X. Closing a dirty tab (via X or the context
  menu's "Close") prompts a confirmation modal via `confirmModal` from
  `@lobehub/ui/base-ui`.
- After save, mutate the SWR cache to the just-saved content before
  clearing the buffer so CodeMirror does not see a stale `value` prop and
  reset the cursor.

Document flow
- For non-markdown documents (`getDocumentRenderMode` → `highlight`),
  render `CodeEditorPane` with a local edit buffer keyed by `documentId`.
- Save calls `documentService.updateDocument({ saveSource: 'manual' })`,
  mutates the document-meta SWR cache, then clears the buffer.

Bump `@lobehub/editor` to ^4.15.0 to pick up the new
`@lobehub/editor/codemirror` subpath export.

* 🐛 fix(portal): force read-only on truncated local file previews

When a file exceeds MAX_PREVIEW_CHARS the preview only holds the first
500k character prefix. Editing and saving against that prefix would
silently overwrite the rest of the file with the truncated content.

Pass `readOnly={truncated}` to the editor, ignore any stale buffer when
truncated, and short-circuit handleSave so Cmd/Ctrl+S is a no-op in this
mode.

* ♻️ refactor(portal): drop MAX_PREVIEW_CHARS truncation for local files

Always pass the full file content to the editor instead of slicing at
500k characters. The truncation existed only to avoid losing data when
saving the previously-Highlighter-rendered prefix, but with full content
available the editor can both display and persist the file safely.

Removes the `truncated` / `truncatedLabel` plumbing, the truncated
banner, and the associated read-only short-circuit in handleSave.

* ✅ test(portal): update document body highlight editor test

# 🚀 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

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)

---
