- backend/go.mod pins gitea.iliadenisov.ru/developer/scrabble-solver v1.0.0; the engine's imports use the published module path; go.work drops the solver replace (GOPRIVATE fetches it directly from Gitea). The solver's wordlist/dictdawg are now public packages. - CI (go-unit, integration): drop the solver sibling-clone, set GOPRIVATE, and download the dictionary DAWG release artifact (scrabble-dawg-<DICT_VERSION>.tar.gz from the new scrabble-dictionary repo) for BACKEND_DICT_DIR. - Docs: ARCHITECTURE §5/§11/§13/§14 + backend/README updated to the published-module + release-artifact model. PLAN.md re-scoped Stage 14 to the split and added Stages 15 (deploy infra & test contour), 16 (prod contour), 17 (dual Telegram bots); TODO-1/TODO-2 marked done.
