- Anchor the message list to the bottom (`reverse: true`) so new messages stay in view instead of landing below the fold. - Move chat history from the OS keystore (O(n²) JSON blob, silent 200-msg cap) to a separate encrypted Drift/SQLCipher DB (`ChatDatabase`): indexed append, uncapped history, dedup as a unique-key invariant. It's an ephemeral per-device cache, isolated from the inventory schema, its migrations, and its sync. No data migration (pre-release). - Add day separators (Today/Yesterday/locale date) and a per-bubble time, all via ICU (12/24h per locale; Localizations locale maps Asturian → Spanish for intl date symbols). - Add peer avatars (deterministic colour from the pubkey + name initial), surface send failures that were previously silent, and make bubble text selectable (addresses, links). - New i18n keys in en/es/pt/ast; tests for grouping, formatting, avatars, scroll anchoring, storage and send errors. Docs: docs/design/chat-storage.md + open-decisions.md.
