-
-The dictionary ships as a versioned **release artifact** (`scrabble-dawg-vX.Y.Z.tar.gz`) from
-[`scrabble-dictionary`](https://gitea.iliadenisov.ru/developer/scrabble-dictionary). The tag is
-a build-time input with **no default** in the images, so it is set in exactly two places to
-move the whole stack — change both to a new release:
-
-1. **CI tests** — `.gitea/workflows/ci.yaml` `env.DICT_VERSION` (the unit/integration jobs
-   download that dawg).
-2. **Deploy seed** — the Gitea repo variables `TEST_DICT_VERSION` / `PROD_DICT_VERSION` (the tag
-   the deploy bakes into a **fresh** volume's image; the deploy job feeds it to `compose` as
-   `DICT_VERSION`).
-
-For local builds set `DICT_VERSION` in `deploy/.env` (template: `.env.example`); a bare
-`docker build` needs `--build-arg DICT_VERSION=vX.Y.Z`. The Dockerfiles and `compose` carry no
-default — a missing value fails loudly instead of baking a stale tag.
-
-Bumping the seed is a **no-op on a live volume** (the `.seed_version` marker wins — the
-seed-drift guard). A running contour/prod moves to a new release **through the admin console**
-`/_gm/dictionary` (upload the tarball, preview the per-variant diff, confirm); in-flight games
-keep their pinned version, new games use the new one (ARCHITECTURE.md §5).
