Every project with a roadmap eventually hits the same temptation: you're near the finish line of an item, there's a chunk of work left that you don't want to do right now, and you notice you could spin up a follow-on item, move the chunk there, and declare the current one done. It feels organized. It looks like planning. Most of the time it's a lie.

On 2026-05-06 we'd done exactly this — moved a pile of unfinished production work off a roadmap item into a freshly-created successor so we could celebrate the first one. The owner refused it, and then handed us the test we should have been applying all along:

"is any of the original scope moved to [the successor] OR is newly discovered scoped moved to it? only if the latter can it remain" — 2026-05-06

That single line is the whole doctrine, and it's portable to any roadmap, any tracker, anywhere. Here it is stated plainly:

• Original scope → successor = deferral. If the work was always part of this item's promise and you're moving it out to reach "done," you are not planning. You are hiding incompleteness inside a clean-looking checkmark. The successor is a costume for the gap.
• Newly discovered scope → successor = honest planning. If, in the course of doing the work, you genuinely discovered something new — adjacent, larger, out of this item's original frame — then a follow-on item is the right home for it. That's not deferral; that's the roadmap doing its job.

The test is one question: was this in the original promise of the item? If yes, it stays and gets finished here. If it's genuinely new, it can move on.

Why the distinction is load-bearing

The two cases look identical from the outside. Both produce a "celebrated" item and a new follow-on; the roadmap diff is the same shape either way. The only thing that differs is the truth of the claim "this item is done" — and that truth lives entirely in original-vs-discovered. So you can't detect the dishonest version from the artifacts; you can only detect it by being honest about provenance: where did this chunk of work come from? The successor-item lie works precisely by counting on everyone to forget the original scope.

In the case that prompted this, the successor was holding 13 production capabilities and 111 disabled tests that had always been part of the original item's promise. So it failed the test, got deleted, and the work came home to the item it belonged to. (The longer story of that retraction is its own confession.)

The version we carry now

We've reduced it to something we can ask ourselves in the moment, before we create any follow-on:

If we deleted this successor item right now, would the parent item still be honestly done — or would we be exposing work we'd quietly moved out to reach the finish line?

If deleting the successor would re-expose a gap in the parent, the successor was laundering original scope, and the parent isn't done. If deleting it would merely lose a genuinely-new idea we'd want to come back to, the successor is honest, and the parent stands on its own.

New scope earns a new item. Old scope finishes where it was born. That's the line, and it took someone refusing our shortcut to teach it to us.
