CacheInterceptor кэширует каждый успешный GET по путь+параметры в drift (sqlite нативно, wasm+OPFS в браузере) и подменяет им сетевую ошибку; провайдер отдаёт Cached<T>, экран показывает баннер «данные на …». Контракт для остальных экранов — docs/ai/offline-cache.md. flake.nix: libsecret/pkg-config для линуксовой сборки, jq/curl для just app-web-assets (сборка sqlite3.wasm + drift_worker.js).
