Digital Buoyancy: Ballast
The reading that treats spending less on the deeper model as a warning worth a look, not automatically a win.
Every cost dashboard in this industry tells you when you spent too much. Almost none of them tell you when you have quietly stopped spending enough. A ship riding high in the water looks efficient from the dock. It is also unstable the moment weather comes in, because the weight that keeps it steady is the weight that is missing. DreamerOS watches your own use for the same pattern. A workspace that has quietly stopped reaching for the deeper model on the calls worth getting right, architecture, security, the decisions that are expensive to get wrong, looks like a saving on a spreadsheet. It is closer to running light.
Ballast compares your last seven days of reaching for the deeper engine against your own trailing four-week average. Never against anyone else's account, and never against a fleet-wide benchmark. A steady week reads as well ballasted. A sharp rise reads as running heavy, which is information, not a violation, and the copy says so plainly. A sharp fall reads as riding high, and that is the state almost nothing in this industry names, because every tool built to watch your spending is built to be happy the moment the number goes down.
The comparison method is borrowed from how training load is read in sports science, adapted for this use, and it is not sold as more certain than it is. It stays quiet rather than guess. Too little history, or nothing yet to compare against, and it says nothing at all instead of a number it cannot stand behind. When it does show a number, the caveat travels with it every time: this compares you against your own recent pattern, not against a validated threshold.
A cost instrument that only watches for overspending optimizes for the wrong failure. The person who quietly stopped asking the deeper model to check architecture or security before shipping is not saving money. They are riding on luck, and Ballast is what tells them before the weather does.
