 **[@mangodxd](https://github.com/mangodxd)** — Type hints cleanup (PR #115)
 Added missing type hints across 10 files and corrected 9 inaccurate existing ones — the kind of maintenance work that makes the codebase easier to reason about.
 
+**[@Argonaut790](https://github.com/Argonaut790)** — HTML entity decode + Traditional Chinese locale (PR #239)
+Fixed double-escaping of HTML entities in `renderMd()` — LLM output containing `<code>` was being escaped a second time, rendering as literal text instead of the intended markdown. The same PR also completed the Simplified Chinese translation (40+ missing keys) and added a full Traditional Chinese (`zh-Hant`) locale.

+**[@indigokarasu](https://github.com/indigokarasu)** — Visual redesign proposal: icon rail + design token system + 7 themes (PR #213)
+A CSS-only redesign of the full UI — proper design tokens (`--bg-primary`, `--text-info`, spacing scale), an icon rail sidebar replacing the emoji tab strip, consistent form cards, breadcrumb nav, and 7 built-in themes as custom properties. The PR didn't merge as-is but directly shaped the design language and theme architecture that shipped in v0.50.0.

+**[@zenc-cp](https://github.com/zenc-cp)** — Anti-hallucination guard for ReAct loop (PR #133)
+Added a streaming token buffer and post-run message scrub to `streaming.py` to detect and strip fake tool execution JSON that weaker models write inline instead of calling tools properly. A three-layer approach: ephemeral anti-hallucination prompt, live token filtering, and session history cleanup. The pattern influenced later streaming.py improvements.
