Memory leaks: follow what keeps an object alive
A Google Chat case study makes retaining paths a useful starting point for investigating memory growth in long-lived web apps.

Start with one repeatable interaction
Vatan Aggarwal and Thierno Thiam describe using Chrome DevTools for agents to investigate Google Chat memory issues. Their reported fixes belong to that project; they are not a measured benefit for Boloop or your app. Start with a reproducible action and an explicit expectation for what should be released.
Read the reference, not just the total
A heap snapshot shows what remains reachable. The Retainers section identifies objects that point to the selected object. In the official documentation example below, an Item instance keeps a string through its x property. This is an explanatory DevTools example, not a Google Chat production snapshot.
Turn the observation into a check
Compare a baseline, the target interaction, and the state after reversing or closing it; repeat the sequence to see whether retention grows. Trace the path and decide whether ownership is expected before changing code. An intentional cache or a large collection of cleaned-up listeners is not automatically a leak.
The agent memory guide describes this three-state approach. Keep the same interaction and conditions when checking a fix. Our related bug-fix verification guide adds reproduction and regression evidence; neither an agent explanation nor one smaller snapshot proves the issue is resolved. Boloop has read the sources but has not run their experiment.
