v1.0.260

✨ New: Claude and Codex model controls

Claude and Codex tabs now have a model picker in the chat header, with the controls each engine actually supports. Claude exposes model, effort, context window, fast mode, and thinking where available; Codex exposes the GPT-5.6 Sol / Terra / Luna models and their supported reasoning levels. Choices are kept with the project tab instead of resetting whenever you move around Cockpit.

✨ New: built-in DevKit and better HTML apps

The HTML Apps panel now includes DevKit, a built-in toolbox for Base64, URLs, JSON, hashes, JWTs, timestamps, and UUIDs. Built-in apps appear as first-class cards without being written into your personal html.json, so they keep working across upgrades and install locations.

HTML apps can also open in a separate browser window directly from the Apps panel, preview toolbar, or file browser. The preview itself gets a clearer title bar, app icon, and backdrop.

✨ New: clearer sessions and live output

Streaming replies now show a live, CJK-aware output count, so long-running answers visibly keep moving. Session panels also share consistent numbered navigation markers, making keyboard destinations easier to identify across recent, project, and global session views.

🐛 Fix: API-key engines and Codex 5.6 transcripts

DeepSeek, GLM, and Kimi now consistently run through Cockpit's Built-in Agent; the old per-tab SDK / built-in switch is gone. Their live model pickers and balance or quota checks remain available, while stale SDK sessions are no longer mixed into the active session list.

Codex GPT-5.6 tool calls now render correctly in both live and resumed transcripts. Cockpit recognizes commands and patches routed through the new exec-script format, preserves their output, and keeps forks aligned with the right tool call.
