# Frontend: 50ms setInterval console-suppression script in root layout
|
|
|
|
**Severity:** high
|
|
**Domain:** Observability
|
|
**Labels:** bug, frontend, logging
|
|
|
|
## Description
|
|
|
|
`src/app/layout.tsx:139` contains a `setInterval` that repeatedly overrides `console.error`/`console.warn` every 50ms. This creates a recurring CPU microtask throughout the page lifecycle. The goal appears to be silencing an Emotion/MUI SSR warning, but the approach overrides the console globally on every tick.
|
|
|
|
## Options
|
|
|
|
1. Remove the suppression script entirely and address the underlying Emotion/MUI SSR warning properly.
|
|
2. Keep one-time suppression (no interval) gated to development only.
|
|
3. Replace with a single non-polling console override applied once at module load.
|
|
|
|
## Recommendation
|
|
|
|
Remove the polling entirely. If the SSR warning must be silenced, apply a single non-polling override and only in development. Coordinate with ISSUE-084 (console suppression masks prod errors).
