Codex Grid is a local developer tool. It reads local Codex thread data through the Codex app-server and serves a browser UI on 127.0.0.1 by default.

LAN access is available only when explicitly requested with --host 0.0.0.0 or HOST=0.0.0.0 ./launch.sh. Do not use LAN mode on an untrusted network; Codex Grid has no authentication layer and displays local Codex thread metadata.

Before publishing changes, check that commits do not include:

• API keys or access tokens.
• .env files.
• Local SQLite databases.
• Private keys or certificates.
• Logs or screenshots containing private thread content.
• Full local filesystem paths from private machines.

Open a GitHub issue with reproduction steps and impact. Do not include secrets or private thread content in the report.
