v1.2.92

✨ New Features

• Session Fork & Message Branching

  • Sessions can now fork from any message and branch into alternative continuations; execution intent is wired through fork paths with a runtime lock.
  • Session schema and migrations, run/response stores, entry handling, ESM guidance, the background run coordinator, and the dispatcher all support forks; TUI session commands/runtime and Web UI chat/sessions views are updated.

• WebUI Trajectory View & Session Log Export

  • A read-only trajectory projection in the Serve Web UI organizes session messages, tool events, and run events by run/turn/step without forking Agent/Runtime state.
  • Server-side session trajectory and export endpoints live under the existing session route, and the session header gains a log download action (optionally including descendant sessions).

• WebUI Modernization with shadcn-svelte & lucide

  • Added Tailwind CSS v4 and shadcn-svelte style components (button, badge, card, dialog, input, switch, tabs, tooltip) with the $lib alias and cn() utility.
  • Replaced text glyphs with lucide-svelte icons across the sidebar, sessions, settings, and list editor views; added a brand logo mark, a workspace filter menu (all/projects/ungrouped), and a Ctrl+Shift+K new-chat shortcut.

• Authored-commit Co-Author Setting

  • A new global "authored" setting (default off) appends the MothX co-author trailer to system prompts, guiding the model to include Co-Authored-By: MothX <harness@mothx.net> when creating git commits.
  • Wired through config persistence, the TUI settings dialog, and the Web UI settings form with bilingual labels.

• New Provider Models

  • DeepSeek (anthropic + openai): added deepseek-v4-flash-vision-exp with 1M context, text+image input, and no default max_tokens.
  • Volcengine codingplan: added doubao-seed-evolving with 1M context and text+image input.

🔧 Improvements

• Default Mode is YOLO

  • New installs and empty-mode fallbacks now use yolo instead of agent: settings.json defaultMode, Serve/API DefaultMode, CLI/TUI/ACP/WebUI, public SDK Builder, and agentruntime policy resolution.
  • Explicit --mode, persisted session mode, and WeChat/Feishu forced yolo still take precedence. Existing configs that set defaultMode: "agent" are unchanged.

• Native Directory Picker for Serve

  • Serve now opens the operating system's native directory picker (macOS, Windows, Unix) for selecting a working directory instead of typing a path.

• Unified Settings Components

  • Extracted shared SettingsField, SettingsSection, SettingsSwitch, and ProviderEditorDetail components and unified settings view layout/styling across AppSettings, ServeConfig, Channels, Env, Logs, Memory, Overview, SkillHub, and WorkDir.

🐛 Bug Fixes

• WebUI Sidebar & Session ID Fixes
  • Sidebar collapsed state now persists in localStorage, with collapse/expand labels.
  • Removed the unused trajectory timeline mode, state, translations, and layout helper.
  • Fixed AllocateSessionID to treat "not registered in DB" as available after sessions.db exists, with a regression test.
