Module chats 

Chat database operations — CRUD for the chats table.

Structs

SlimChatDB

Slim version of Chat for database storage.

Functions

clear_chat_last_read

Upsert a chat to the database. Clear a chat’s read marker to never-read. The save_slim_chat upsert deliberately refuses to regress last_read to empty (a partially-hydrated STATE chat would otherwise wipe the stored position), so a DELIBERATE clear — Mark as Unread on a chat whose only message is the target — must come through here or it silently no-ops.

delete_chat

Delete a chat and all its messages from the database. chat_identifier is the string id (npub for DMs, channel id for Communities) — NOT the integer PK.

get_all_chats

Get all chats from the database.
