A card is one piece of your world, with its origin attached.
Everything in Reraise is built from cards. A card keeps apart what is proven, what was said and what you believe, and it always says where it comes from.
A card is a structured piece of a world, not a text file.
A card is not a note in a folder. It is a structured piece of a world, and it carries its context: where it came from, who made it, who may see it, and what it connects to.
A card can be a person, an organisation, an event, a claim, a source, an experience, a relationship, an assumption, a decision, a rule or a topic.
Cards connect through typed links. One card supports another, refutes it, cites it, is based on it or depends on it. Each link records who drew it: a person or a named agent. And one card can live in several worlds without being copied; how worlds work is on How it works.

Proven, said and believed never melt into one truth.
Every card separates three things. Proven: it traces back to a source or an original. Said: somebody claimed it. Believed: you yourself think it is right.
These three never melt into one central truth. A claim that a thousand people repeat is still said, not proven. Your conclusion about a market, drawn from your own deals and contacts, is not a proven fact either. For your decisions it may be worth the most. It stays yours.
| Layer | What it means | When you share the card |
|---|---|---|
| Proven | Traces to a source or an original | Travels, with its origin |
| Said | Someone claimed it, and the card names who | Travels, with its origin |
| Believed | Your own stance, set only by you | Never travels |
To be precise about the file: a card file has three layers, and they are evidenced (shown as proven on this site), said and experience. Believed is not one of them. It is your stance on a card, stored next to the card, not in it: believed, rejected or undecided, with a note if you want one. It lives on your device. Agents can lay cards and make cards, but only you set what you believe.
Believed is your private stance, kept apart from the card and never shared.
06Proven. Said. Believed.0:36
Your own experience is evidence of its own kind.
A well-known psychologist says method X works. That is one thing. I used method X five times, and it worked four times. That is another.
The second is not proof of a universal truth. It is real personal evidence: under these conditions, with this person, this approach worked. That is why experience has its own layer in the card file, apart from evidenced and said, and why an experience card must name its author. The thinkers you admire appear as sources, not as truth. You decide what weight they get.
The most important source is you.
14Your experience is evidence0:40
Every card says where it comes from, and copies count back to their origin.
Origin is mandatory. A proven or said card names its source, or the system it came from. An experience card names its author. Every card says who made it, a person or a named agent. A card that breaks these rules is not written.
Ten thousand people sharing the same news wire story are not ten thousand independent confirmations. Source A is the original report. B quotes A. An analyst quotes B. An article is built on the analyst. Four cards, and maybe one independent source. Because every card keeps its origin, copies are counted back to it, and the real question becomes how independent a piece of information is.
Three example cards show the three layers side by side.
Gold closed higher on the day
Source: the exchange's own published closing price for that date, linked. Anyone can open the original and check it. That is what makes this card proven.
A podcast guest says vitamin D prevents winter colds
Source: the episode, with the minute the claim is made. The card records that the claim was made and by whom. Whether it is true is a separate question.
The finca came through a local contact, not a listing
Author: me. Two earlier attempts through listing portals failed on price. Not proof of how the Mallorca market works. Real evidence of how it worked for me.
All three are illustrative. They name no real study, person or price.
A card file is plain Markdown, and the format is open.
Each card is one Markdown file. A small header block at the top holds the essentials: id, type, title, layer, source, date, author and the worlds the card belongs to. The text follows below. Further fields say who may see the card and whether it may be used to train a model; training is off unless you switch it on.
The files are the truth: any database or search index is derived from them and can be rebuilt. Nothing is deleted; a rewrite archives the previous version. The card format v2 is licensed under Apache 2.0, so any tool can read and write it. More on Open.
Cards can travel to other websites and to the exchange.
On this site, every numbered citation opens a card: the claim, who made it, where, and a link to the original. A quote is never just a quote; it links to its card. Any website can embed a card from the exchange the same way: a small mark after the sentence opens the card, with its origin attached. See it on an ordinary page.
Cards are brought in and taken at the exchange, the trade page (beta): you sign up, bring in a public card and take cards. Only what is publicly findable is shared there; your conclusions and beliefs never travel. Every trading partner gets a running number, and standing comes from origin and proof, never from volume. The rules are on Trading rules.
