Phase 434: home-mode mention ingest and notification error logging (v0.8.397).

Persist guild inbound handler as ingestInboundGuildMessage for home view, resolve mentions from DB members when guild mesh is detached, and add structured error logs for mark-all, open notification, and mark-channel-read.

 **v0.8.115:** `loadGuild` / `_openGuild` clears stale `activeChannelId`, then `_selectGuildChannelWithUnread` picks mention-weighted unread channels before falling back to the first text channel. `setSearch` records `searchRecentByGuild` in user prefs. View: `searchRecentQueries`.
 
+**v0.8.397:** `ingestInboundGuildMessage(msg)` processes guild mesh gossip while on home (mention alerts + inbox via DB member lookup). `markAllNotificationsRead` / `openNotificationTarget` / `markChannelRead` log structured errors. Smoke helper: `simulateGuildMessage(platform, msg)` in `smoke-runner.cjs`.
+
 **v0.8.252:** Guild search mesh skipped when `guildOpenNoViewableChannels`; emoji batch prefetch skips negative miss TTL; sticker gossip prefetch gated on `attachments`; `session.startup` logs INFO when initial guild mesh flush was bounded. Smoke: `test:guild-search-no-viewable-skip`, `test:sticker-prefetch-attachments-ready`.
 
 **v0.8.248:** Guild open filters unread/last picks with `_canViewChannel`; sets `guildOpenNoViewableChannels` when none accessible; defers `_ensureGuildModules` via `setTimeout(0)` after channel pick; emoji mesh prefetch clears miss cache on success. Smokes: `test:guild-viewable-channel-pick`, `test:guild-open-no-viewable`, `test:guild-plain-beats-dual-combo`.
