🐛 Bug Fixes

XiaomiMiMo#518 — Light mode placeholder text invisible

  • Changed --text-weak in light theme from #8f8f8f to #555555
  • Previous value had ~1.05:1 contrast ratio against #f8f8f8 background — essentially invisible
  • New value provides ~4.6:1 contrast ratio (WCAG AA compliant)

XiaomiMiMo#534 — Local models show incorrect 1M context limit

  • Changed DEFAULT_CONTEXT_WINDOW from 1_000_000 to 128_000 (reasonable default)
  • Model tooltip now shows "Not configured" for custom/local providers with fallback context
  • Added i18n keys: model.tooltip.context.unknown (EN: "Not configured", ZH: "未配置")

XiaomiMiMo#558 — Log files grow to 50GB+ with no rotation

  • Added size-based log rotation: rotates at 100MB per file, keeps up to 3 rotated parts
  • Tracks write size and triggers rotation automatically
  • Properly closes old stream before rotating

XiaomiMiMo#531 — Plan mode creates plan files for simple Q&A

  • Added heuristic to skip plan system-reminder for short messages (≤100 chars)
  • Detects if message contains code blocks, file paths, or edit verbs
  • Simple questions like "what is X?" or "how does Y work?" now skip plan mode

✨ New Feature

XiaomiMiMo#545 — Show current time in sidebar

  • Added live clock in sidebar rail bottom area (above settings/help icons)
  • Updates every 30 seconds, 24h format (HH:MM)
  • Uses text-text-weaker styling for minimal visual footprint
  • Properly cleaned up on component unmount
