History was selected by msg_to, so whoever next held a released nick, or created a deleted channel again under its old name, could read the earlier holder's messages. Each message row now records the session a DM or INVITE was sent to (to_session_id) and the channel a channel message was sent to (to_channel_id), and GET /api/v1/history selects by the one that applies, using its index. A session's DM history now also follows it across nick changes. A DM or channel message whose recipient is deleted before it is stored gets the unknown nick or channel error. Model: opus-5-5
