- Audit report: 09 - Audits/Full Codebase Audit - 2026-05-30.md
- 81 issue files ISSUE-055..135 (decisions + 1 skipped no-brainer).
- Scanner docs from scratch (was zero): architecture, data model, API ref, payment
  flow, operations runbook + repo README.
- Doc-sync updates across API reference, data models, flows, design system.
- Secret Rotation Runbook (08 - Operations) for the exposed credentials.
- Reusable workflow guide (07 - Development) + .claude/workflows/full-codebase-audit.js.

Issues remain status:open intentionally — the code fixes are uncommitted-then-committed
working-tree changes per repo and aren't "resolved" until merged/deployed.

# 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).
