v0.49.1

v0.49.1 — 2026-10-15

Added

• A successor thread can run on a different implementer: backend, model and reasoning effort. lucidos successor spawn takes --coding-agent, --coding-agent-model and --reasoning-effort.
• In a coding-agent thread on the Lucidos source, a plan's Implement in a new thread option names the implementer. The planning agent recommends one and says why, and you can take it or keep this thread's.

Changed

• Claude models on OpenRouter use prompt caching, and cache writes are priced.
• Coding-agent usage records the model that served each reply, so a sub-agent's calls can be priced.

Fixed

• A coding agent that exits on its own, for example when Claude Code cannot reach its login gateway, fails the turn with a card that shows its own error message, masked for secrets. Try again sends the message it never read.
• A phone with the desktop app open offers Update Desktop App as soon as a release is published, without waiting for the hourly release check.
• Check for updates shows on a phone, and says so when the check fails.
• With the theme on System, the app and its app frames keep the right light or dark mode after a slow start, a theme change or a hidden tab.
• The Home rail toggle shows whenever Home exists, so an empty board still has Add.
• The Home rail's divider runs up through the header, and its toggle matches the header icons.
