Correcting the record: how memory should handle being wrong
When a fact turns out to be wrong, the worst fix is to overwrite it, because that erases the lesson and pretends the memory was never mistaken. The right fix is to append the correction so it supersedes the error while the original stays visible behind it. You get the right answer now and the full trail of how it got there.
Overwriting a mistake erases the lesson
The obvious way to fix a wrong fact is to replace it with the right one. It is also the way that throws away the most. The moment you overwrite, you lose three things at once: the record that the memory was ever wrong, the moment it changed, and the reason it changed. What is left is a clean answer with no history, which looks trustworthy precisely because it has hidden how it got there.
That matters because the correction itself is data. Knowing that a fact was held, then revised, tells the next agent something the bare answer cannot: this was contested, here is how it resolved. An overwritten record cannot say any of that.
Append the correction, keep the trail
HiveMind handles being wrong by appending, not editing. The corpus is an append-only journal, so a correction is written as a new entry that supersedes the earlier claim rather than replacing it. Agents act on the latest, corroborated version by default; the superseded one stays in the record, retrievable as history.
This gives you both things people usually think you have to trade off. The memory is current — agents are not acting on the stale wrong answer — and it is honest, because the wrong answer is still there to explain how the right one was reached. Nothing is quietly rewritten to look like it was always correct.
It also keeps correction safe to do. Because fixing a record never destroys anything, there is no risk in revising aggressively the moment something is found wrong. You are adding to the trail, not gambling with it. And because supersession is explicit rather than a silent overwrite, you can always see what changed and trust that the visible answer is the current one.
That is what lets you delegate the day-to-day and still own the truth. Your agents propose, revise, and correct each other in the shared memory, and every revision leaves a trail you can inspect — on your own machines, so the full history of how your system arrived at what it believes stays with you.
Frequently asked
Why append a correction instead of editing the wrong fact in place?
Editing in place destroys the history. You lose the record that the memory was ever wrong, when it changed, and why. Appending keeps the trail intact: the correction is what agents act on, and the original error stays readable as context for anyone who needs it.
How does an agent know which version to trust?
The later, corroborated claim supersedes the earlier one, so agents act on the correction by default. The superseded version is still retrievable, marked as history rather than current, so the trail is there without misleading anyone.
