The dictionary lives on a persistent volume seeded from the image once and never re-seeded, so a redeploy that bumped BACKEND_DICT_VERSION left the new DAWGs unreachable (the volume mount shadows the image copy) and the active version stuck at whatever the admin console last installed — a native offline-first client then fetched the server's older pinned version over the network instead of using its bundled dict. On boot the backend now DELIVERS the build version onto the volume add-only, from a second unshadowed image copy at BACKEND_DICT_SEED_DIR, into DICT_DIR/<version>/ when absent (the flat seed and prior uploads untouched, so in-flight games keep theirs), and InitActiveVersion makes the build version active — except a console-installed version NEWER than the build (compared numerically) is not downgraded by a restart. The .seed_version guard still protects the flat seed's label (a bump is a new subdirectory, never a relabel). The console stays for out-of-band updates. Docs: ARCHITECTURE.md §5, deploy/README.md, seedmarker.go. Tests: engine.DeliverVersion (add-only, idempotent, flat-seed skip), compareDictVersions, and the dictionary-update integration test's deploy-delivers path.
