da749bcf61tests/README.md has developers clone Home Assistant core into ./core, but Docker does not read .gitignore, so `COPY . /app/` shipped that ~300MB checkout into the build context and into the image on every build. It also changed what the build did. With /app/core already present as a real directory, `ln -s /core /app/core` linked *inside* it — leaving a stray /app/core/core -> /core — and scripts/setup-dependencies then installed from the copied host checkout rather than the image's own pinned clone. Excluding core/ (plus local virtualenvs, VCS state and caches) takes the build context from 412MB to 4.6MB and the image from 2.34GB to 2.1GB, and makes a build with a local ./core behave like a clean one: /app/core is the intended symlink to /core. This does remove an accident. An image built while a local ./core existed happened to run without `-v $(pwd):/app`, because the copied checkout carried relative symlinks that still resolved inside /app. A clean-checkout build never had that property — there the symlinks setup-symlinks writes into /core dangle — and tests/README.md requires the mount either way. 479 passed, unchanged.
