The distinction holds up in practice. What I found is that memory is only useful if writing is cheap and forgetting is deliberate. Accumulating notes is easy. The failure is stale entries, true when written and quietly wrong later, so anything recalled gets checked against the current repo before it is acted on. Retrieval is the easy half. Expiry is the other one.

That’s exactly the hard part. Memory should not just know what to keep, it should know when something has stopped being true. Cheap writes are useful, but deliberate forgetting may be what keeps memory trustworthy as the system evolves.

I run a small finishing contractor in Lithuania, and the write gate is the part we got wrong first.

We started by saving everything into one project file. Within a month it held three versions of the same warranty wording and two supplier prices, and nobody on the crew trusted it. The file stopped being memory and became noise.

Now only checked facts go in, each with the date beside it. That one rule did more for us than any bigger model. Whether it holds when the crew grows is something I do not know yet.

Dated facts beating a bigger model matches what I keep finding too. My version is checking a measurement before the cut instead of after. The date next to each fact is what makes “checked” mean something later, otherwise you’re back to guessing which version to trust. Curious what breaks first once the crew grows: the habit of dating things, or someone skipping the check because it’s slower.

This is a great real-world example. Memory only becomes useful when people can trust what goes into it. Your rule of saving only verified facts with dates is simple, but that kind of discipline is exactly what makes a memory system work.

The "consult before write" rule is the one I'd steal first. I keep making a physical version of the same mistake: skip the research pass, do the work, find the missing fact after the fact. Learned that outdoor plywood needs epoxy on the edges and sacrificial feet under the legs from an AI research session, a couple hours, but only after I'd already shot the product photos of a table that skipped both. A write gate before the next project starts would have saved a full reshoot.

That is such a practical example of why consult before writing matters beyond AI. One missing fact can seem small at the beginning but become expensive once the work is finished. Your table story captures the value of a write gate perfectly.

Exactly. Checking a measurement before the cut costs a minute. Checking after costs the whole board. Same math applies to a fact an agent never verified before it started writing.

Yes, right
