Adds three WhatsApp-standard affordances to the inbox: per-message
emoji reactions, reply-with-quote, and copy-text. Bubbles stay pure
presenters — actions layer on by composition (MessageActions wraps
MessageBubble). Hover toolbar on desktop, long-press (onContextMenu)
on touch.
Data model (migration 009):
- messages.reply_to_message_id (self-FK, ON DELETE SET NULL) so replies
survive a deleted parent
- message_reactions table — one row per (message, actor) with a unique
constraint, conversation_id denormalised so Supabase Realtime can
filter without a join
- RLS scoped via conversation ownership; service-role bypass for the
webhook
API:
- /api/whatsapp/send accepts reply_to_message_id, resolves the parent's
Meta message_id and forwards it as context.message_id
- /api/whatsapp/react (new) sends Meta reaction payloads and mirrors
the upsert/delete into message_reactions
- Webhook stops storing inbound reactions as fake text messages and
instead upserts/deletes message_reactions; inbound replies (context.id)
resolve to internal UUID and populate reply_to_message_id
UI:
- MessageActions hover toolbar with inline 6-emoji Popover (static set;
no emoji-picker library)
- ReplyQuote shared between the in-bubble quote and the composer chip
- MessageReactions pill row with click-to-toggle
- Thread subscribes to message_reactions filtered by conversation_id;
optimistic upsert with rollback on failure
