## TL;DR

Cloudflare Pages deployments give agents production and preview evidence: build command, output directory, exit code, deployment URL, environment, and function logs.

## Core Explanation

A Pages deployment failure is not always a source-code failure. Agents should inspect the build command, output directory, root directory, environment variables, branch deployment type, and exact deployment logs before changing application code or workflow configuration.

Preview deployments are especially useful because they separate "what will be published" from the production site. A good agent evidence trail records the preview URL, branch alias, commit SHA, production or preview environment, and whether Pages Functions logs show request errors, uncaught exceptions, or custom `console.log` output.
