“Why is this 8,000?” has an answer.
Every forecast cell records who set it, when, and whether it was a person or the system. Override anything you like — the override keeps your name on it, which is what makes disagreeing with the forecast safe.
Override anything, and own it
You know things the model does not: the broker went quiet, the co-man slipped, the competitor is out of stock. Type the number. Planster keeps it, and keeps your name and the date attached to it.
Person or system, always distinguishable
A cell the engine forecast and a cell someone typed look different, because they are different. The one you can trust to update itself and the one that is frozen at whatever you last believed are not the same number.
The meeting gets shorter
The argument about whose spreadsheet is right ends when the cell says who set it and when. Sales and ops stop reconciling versions and start disagreeing about the actual decision, which is the disagreement worth having.
What the agent does with provenance
Every night
This is what makes the agent’s answers checkable. Every figure it reports carries provenance — "4,212 units on hand, as of last night’s sync" — linked to the screen showing the same number. A figure it cannot link to, it does not state.
What it can’t do
It cannot edit a forecast cell or overwrite your override. Anything it produces is a draft with its own stamp on it, and drafts are not the plan.
The number nobody could explain
A quarterly plan review stalls on a single line: 8,000 units for a SKU that has never done more than 5,000. Nobody in the room set it, and the spreadsheet does not remember. That meeting costs forty minutes and ends with someone promising to look into it. In Planster the cell says who typed it, when, and against which scenario, and the review keeps moving.
How it fits together
Every capability runs on the same demand forecast, so each one makes the others more useful.
Your own numbers
When you want your number kept separately rather than as an override, set a manual plan and keep it next to the forecast.

Promoted scenarios live as visible layers over the base forecast, so a cell can show you the whole arithmetic that produced it.
