Organize these invented requests into a waiting-for tracker. Columns: request, recipient role, sent reference, promised response date, my review date, dependency, next proposed action, closure evidence. Preserve the difference between someone else's promise and my own review date. Use unknown when a fact is missing. Do not infer lateness or send any messages.
R1: On Monday I asked the room coordinator whether the room is available. No response date was promised. I want to review this Thursday. An event date depends on the answer.
R2: On Tuesday I asked a colleague for the approved poster file. They said they would send it Friday. I will check Friday afternoon. The print proof depends on the file.
R3: I asked whether a volunteer can help. They replied that they cannot. No replacement has been requested.
