Source policy and July 2026 snapshot Use primary documentation and inspect the installed versions before applying version-specific guidance. Re-check release notes when freshness matters; do not freeze the skill to the versions visible when it was authored. Snapshot verified 2026-07-14: - Docker Engine release notes list 29.6.1 (2026-06-26). - Docker Compose releases list 5.3.1 (2026-07-07). - Traefik releases list 3.7.7 (2026-07-08), with maintained 3.6 and 2.11 lines also visible. - The actual Coolify-managed proxy may use a different supported Traefik line. Detect it before selecting syntax or migration advice. ## 2.
