Probe a target for accidentally-served secret-bearing files in the web root — `.git/`, `.env`, `.DS_Store`, backup files, database dumps, key files, CI configs, IDE configs. Use when: post-deploy verification on a new release, or SOC2 auditor asked "what's reachable in the web root that shouldn't be," or a bug-bounty report hints at a leaked file. Threshold: any of the canonical 40+ paths returns 200 OR returns a body matching the expected fingerprint of the file type (e.g., `.git/HEAD` returns content starting with `ref:` or a 40-char hex SHA). Trigger with: "check exposed files", "git directory exposure", "env file leak", "backup file scan".
