The one line it's built on: everywhere else a claim and its evidence are separate things: the claim travels, the evidence stays behind. Here they're the same object. Every source or connection gets a code, like SRC-0034. Write that code anywhere, a comment, an argument, a connection, and it becomes a live citation carrying that document's verification status with it. You can't quote a source without also quoting how well it's been established that it says what you say it says. If it's contested next year, every place it was ever cited says so. From the sources you build maps. Propose a connection, X owns Y, X paid Y, X is linked to Y, with your reasoning and your sources; three people endorse it with theirs; it enters a shared graph for good. Three graphs: who's connected to whom, who gave what to whom, who owns what. The last one computes the real stake through a chain of holdings, so you get the actual owner, not the name on the letterhead. There's a private side too. Follow a source, an entity, a dispute, and it tells you what moved around them while you were away, a new verification, a contestation, a new citation, and draws all of it as a map of your own. Nobody can see what you follow.

Pyramid: owns, part of, manages Until now every connection in Pyramid meant "owns n%". There was no honest way to say that a division belongs to its company, or that a manager runs a fund it doesn't own. Now each connection has a nature: Owns — a stake, as before. Every existing connection stays Owns. Part of — a division or branch of a larger entity. No percentage. Manages — runs it without owning it: an asset manager and its fund, a trustee and its trust. No percentage. Proposing. Pick the nature first; the stake only appears for Owns. Under the fields you read the exact sentence you are proposing.

Who owns a company is rarely written on one document: it hides in a chain of holdings. Here members rebuild those chains one stake at a time, each link carrying the filing it came from, and nothing joins the map until three other people have checked it. Reading is open.

Traces is now live! The things you follow, what moved around them while you were away, and how they hold together. The one page on Cittadelle that belongs to you alone: nobody else can see it. An investigation is a web of sources, contestations, entities and Briefs that need watching together. Until now that web lived in each member's head, or in a file of their own. Traces keeps it on the platform. Press ∴ Trace, next to Share, on anything you want to follow, and it joins ∴ Traces in your sidebar, with everything that moves around it from then on.
