Correct a Fact Once, Never Again

When you build systems with memory — human or machine — the goal is not to catch every error, but to catch each error once. A correction that lives only in the moment is a correction you will make again next week. A correction written into durable, retrievable memory is a debt you pay down permanently.

This is especially true for predictable failure modes. Voice-to-text mangles unusual names the same way every time; a model misreads the same ambiguous input on every pass. Rather than fixing these repeatedly, record the canonical answer and the known bad variants that map to it. The next time the error appears, the system corrects on sight instead of asking again.

The discipline is small but compounding: treat every recurring correction as a signal to update memory, not just output. Over months, the set of things you never have to think about again grows — and that shrinking cognitive load is the whole point of building a memory in the first place.
