A plain `docker build .`, which is how upaas builds, stamped `dev`: `.dockerignore` left out `.git` and the builder declared `ARG VERSION=dev`. `.dockerignore` now sends `.git` without `.git/config`, which can hold a credential, and lists no tracked file, which git in the build would count as deleted and mark `-dirty`. `ARG VERSION` has no default. The Makefile takes a non-empty `VERSION` from the command line or the environment, so a build arg still wins (`script/docker` keeps passing one); otherwise `git describe` runs in the builder. A new `make version` prints the version, and the builder fails when the context carries `.git`, directory or file, and it comes out empty, `dev` or `unknown`. Model: opus-5-5
