For an honest-AI (vs_ai) game the comms hub relied on a post-mount $effect to
switch from the Chat tab to the Dictionary, so ChatScreen mounted for a beat
and fired its chat/state fetch over the network. Online that was a wasted
call; offline it threw and raised a 'something went wrong' toast on entering
the word-check form (the check itself already worked). Start the comms hub on
the Dictionary tab immediately for a vs_ai game, so ChatScreen never mounts.
Two offline bugs found on the contour:
- The word-check screen (CheckScreen) called gateway.gameState/checkWord
directly, so in an offline (local) game it hit the network and errored
("something went wrong"). Route both through gameSource(id) — the local
source answers from the device dawg. The complaint control (online-only,
no offline backend) is hidden for a local game.
- The lobby did not react to the offline-mode toggle (which lives in Settings,
so the lobby can stay mounted): an online game lingered until the next
reload. Reload on an offlineMode flip so entering offline immediately shows
only device-local games.
Cold offline launch hanging on the splash (boot still fetches the profile over
the network) is the separate C2 offline-boot follow-up (needs a persisted
profile + a boot short-circuit).
In offline mode the lobby now shows only the device-local games and its
New-vs-AI entry creates one through the in-browser engine — the visible
payoff of the offline mode.
- LocalSource.list() reconstructs a lobby GameView per stored local game by
replay, exposed through the lazy gamesource proxy; unit-tested via an
in-memory store.
- Lobby.load() branches on offlineMode: lists local games and skips every
gateway call (no online games/invitations/incoming); the Stats tab is
disabled offline.
- NewGame offline: find() creates a device-local vs_ai game via
LocalSource.create using the profile's advertised dict version + a local
seed; the friends flow and the random-opponent option are hidden, and the
variant picker / Start are enabled offline (were gated on connection).
- id.ts: newLocalGameId + randomSeed (tested).

Deferred to fast-follow: the Settings Friends/Profile/Feedback affordance
gating, the flip-to-offline readiness wait, the offline mock e2e (needs
mock-dawg support), and the local-hint UI. The offline flow is verified on
the test contour — the mock e2e cannot enter offline mode (the toggle is
gated to an installed PWA).
