Fan-out warning (before one click starts too much for this computer)

What it is

The warning compares the number you are about to start with what this computer has been measured to handle, minus what is already running. If it fits, nothing appears. If it is too many, you see:

• The numbers. How many will start, about how many this computer handles well, and how many are already running.
• What happens. "This may slow your computer down", or, past twice the safe number, "This may freeze your computer".
• Three choices. Start the safer amount, start all anyway, or go back and change it.

If Omniscio has not measured this computer yet, it estimates from the computer's memory and says it is an estimate. If the check itself fails, it still warns rather than starting silently.

Where you see it today

• Nighty Tidy, desktop Run page. Clicking Start Run checks first. The page also opens at this computer's safe pace instead of All at once; All at once is still one click away.
• Nighty Tidy spend cap. Once tonight's Nighty Tidy spend reaches your cap, a hand-started run (or an approved agent run) starts no new audit and says why. Audits already running finish. The spend counted is the same number the overnight schedule uses, so audits still running count before their final cost is in.

More places that start many sessions at once (recipes, swarms, bake-offs, bulk restarts and others) get the same warning in later updates.

Why it exists

On 28 October 2026 a single hand-started Nighty Tidy run launched about 145 audits at once on a 24 GB Mac. Memory filled, about $529 was spent and the app crashed. Nothing warned before the click.
