0.1.2-lazurio.5: opening the right panel crashes Chat with React #301 (too many re-renders) #135

What happens

In 0.1.2-lazurio.5, clicking Toggle right panel in Chat crashes the web app: "Something went wrong", Minified React error pingdotgg#301 (too many re-renders). The thread's panel state is persisted, so that thread then crashes on every load. Other threads work.

Reproduced on the Ring 0 reference Environment on 2026-10-27 and reported on a work Environment.

Affected versions

• 0.1.2-lazurio.5 only.
• Not affected: 0.1.2-lazurio.4, the preview 0.1.2-preview.20261026.1 (the same code as .4), and earlier versions. Their compiled ChatView memoizes the panel value.

Cause

f607827395 reads the thread's panel through a plain function, buddyRightPanelState(buddySurface, useRightPanelStore(...)).

• The React Compiler treats a plain function's result as mutable, so it stops memoizing the panel's presence value built from it.
• usePanelPresence sets state during render whenever that value changes identity. With a fresh object on every render, an open panel loops.

Recovering a stuck thread

Nothing is lost; the panel only closes and its tabs stay. On the crashing page, open the browser console and run:

const k="t3code:right-panel-state:v2",s=JSON.parse(localStorage.getItem(k));for(const p of Object.values(s.state.byThreadKey))p.isOpen=false;localStorage.setItem(k,JSON.stringify(s));location.reload()

Fix

#134 moves the Buddy seam into the store's selector, for the right panel and the terminal drawer. It ships as 0.1.2-lazurio.6.
