Two pre-existing offline bugs, both exposed once offline mode became usable (cold boot +
toggling), owner-reported on the contour.
Bug 1 -- offline tiles render weight 0. The rack/board read tile values from the
lib/alphabet cache, populated only by the online wire codec (server-sent alphabet) or the
mock (so the e2e masked it). A local game never goes through the codec, so on a cold
offline boot with no prior online session the cache was empty and every value read 0
(scores stayed correct -- they come from the offline ruleset). Fix: the local source
seeds lib/alphabet from the static offline ruleset (letters + values) when it builds a
game view.
Bug 2 -- the lobby showed (and could open) the other mode's game after a toggle. Two
causes: (a) the lobby cache was not mode-tagged, so getLobby() instant-rendered the last
snapshot regardless of mode; (b) load() wrote the module list after an await with no
generation guard, so a slow online gamesList() finishing after a fast offline list() (or
vice versa) left the wrong mode's games on screen. Fix: tag the snapshot with offline and
gate getLobby() on it; add a load-sequence guard so only the latest load() writes.
- localgame/source.ts: ensureAlphabet from the ruleset in gameView (+ unit test).
- lobbycache.ts: LobbySnapshot.offline + getLobby(offline) mode check (+ tests).
- Lobby.svelte: setLobby tags the mode; load() carries a generation guard.
