# certification-image — builds and publishes the GPU certification image
# (docker/certification/Dockerfile.gpu) that vast.ai certification runs boot
# (#14548, epic #14541). The image bakes everything the 16 KB onstart script
# cannot carry: CUDA llama-server, the sha256-pinned gpu-vision models,
# node24/bun/playwright/tesseract/ffmpeg. Pushes
# ghcr.io/elizaos/certification-gpu:{latest,sha-<short>} via GITHUB_TOKEN —
# no extra registry secret. Rebuilds are rare (image inputs only), so this
# triggers on dispatch plus pushes that touch its own inputs, never on PRs.
