Summarise a long group chat about weekend plans so you know what was actually decided

Forty messages, three changed times, and someone asking again what time to actually turn up because nobody can face scrolling back through it all. This reads the whole thread and tells you what was actually confirmed, who is coming, and what is still hanging, flagging any point where the plan visibly changed partway through.

Summarise this group chat conversation about weekend plans: [paste the group chat messages here]. Tell me exactly what was decided, including the time, place and who is confirmed to be coming, and separate that clearly from anything still undecided or waiting on someone's reply. If two messages in the chat contradict each other, such as the time changing partway through, point out the contradiction and state which appears to be the final version based on the most recent message. Keep the summary under 120 words.
