Decisions
How Listspace remembers
Your AI can't overrule what you decided.
Listspace keeps what you decided apart from everything else that comes up in a chat. Here is how, in plain words.
What was said, and what was decided
A board collects a lot: notes, ideas, old plans and whatever came up in a chat. To your AI it all looks equally true.
A decision is different. It marks what holds now, and your AI works from it. So Listspace keeps the two apart: what was said stays a note, and what you decided becomes a decision.
Everything starts as Proposed
When you pick an option in a chat, or say yes to something your AI suggested, your AI writes it down as a decision. It starts as Proposed.
Your AI never treats a Proposed decision as decided. Want to mark something as decided yourself? Open the item, choose More, then Mark as decision.
Only you confirm
Your AI can't confirm a decision on its own. You confirm it in Listspace, from your daily summary, or on your AI app's confirm screen.
Once you confirm it, the decision is Confirmed: what the board holds as true. Every AI you connect reads the same confirmed decisions at the start of a chat.
A sealed history that only grows
Every decision keeps its history: who proposed it, who confirmed it, every change, and the reason for each. Nothing in it is ever edited. New entries are only added.
Each entry is sealed to the one before it, and Listspace checks the whole history every time you open a decision. If something does not add up, the decision says so in red.
Nothing is erased
You change your mind by replacing a decision or withdrawing it. The old one stays on the board as Replaced or Withdrawn, and the history keeps who changed it, when and why.
So months later you can still see what you decided before, and what made you change it.
A conflict shows both sides
When two decisions disagree, Listspace shows both, marked Conflict. Neither counts until you choose Keep this one on the one that holds.
When your AI proposes a new answer to a question you already decided, you see which decision it replaces, and what the new one leaves out, before you accept.
Still true?
A decision that held in spring can be wrong by autumn. When a confirmed decision has had no change and no confirmation for 180 days, Tidy up in the board's menu asks: still true?
One click keeps it, and the history notes who confirmed it again. Or withdraw it, with a reason. Only a person can confirm a decision again.
How it turned out
Later you know how a decision played out. Add that as an outcome: worked, mixed or didn't work, with a note and links to the items that show it.
Your AI reads the latest outcome with each decision, so it weighs what worked, not only why you chose it. An outcome is never edited: when things change again, you add a new one.
Your AI proposes. You decide.
Your AI can write a decision down, propose to replace or withdraw one, and propose an outcome. Each proposal waits for you with its reason, and nothing changes until you accept it.
That holds at every agent access level, Full included.
You can switch it off
Decisions are optional. On a groceries list or a trip plan you may not want them. Switch them off for one board in the board's menu under Board settings, or for the boards you make from now on in Settings > Your AI, under Decisions on new boards.
On a board with decisions off, your AI adds what you decided as a normal item, with the reason.

The research behind it
Decisions in Listspace are built on Constance, Yellow House Digital's model for AI memory you can trust. Its one rule: no claim becomes truth without a decision a person owns. Constance comes from Jordi Buskermolen's writing on memory for AI that works with you over time.
