Evidence Map
Claims on one side, sources on the other, and a line for every link: solid for supports, dashed red for contradicts, dotted for context. Select one to light its links and read the notes, filter by relation, review a claim's status, and switch to a list view, which narrow screens get by default.

The decision inside it
A link is a citation, not proof
Links drawn by a model are labelled unchecked, review status is kept separate from the links, and the copy never says a source proves a claim.
Installation
How you get it
Paste this into Claude Code, Cursor, Codex or any coding agent. It installs the file and uses it as it is, instead of writing a new one.
Use Layro's Evidence Map for this.
Install it: npx shadcn@latest add @layro/evidence-map
Import it from @/components/ui/evidence-map.
Do not rewrite or restyle it. Pass my data through its props
and keep its built-in states.For the full brief with every prop and the mistakes assistants usually make, use Copy prompt above. Pro components install through the @layro registry with your CLI token: see the Namespaced tab.
API
“Copy prompt” above puts a full brief on your clipboard — install command, dependencies, props, and the mistakes an assistant usually makes with this component.
Props
Read from the component’s own TypeScript interface when the site is built, so this table cannot drift from the file you install.
| Prop | Type | Notes |
|---|---|---|
nodesrequired | EvidenceNode[] | — |
edgesrequired | EvidenceEdge[] | — |
selectedNodeId | string | null | — |
defaultSelectedNodeId | string | null | — |
onNodeSelect | (node: EvidenceNode | null) => void | — |
onOpenSource | (node: EvidenceNode) => void | Open a source yourself. Without it, an http(s) `sourceUrl` opens in a new tab. |
onStatusChange | (claimId: string, status: EvidenceStatus) => void | Promise<void> | Adds review buttons to claims. May return a promise. |
layout | "map" | "list" | `map` or `list`. The map turns into the list below 640px wide. |
linkedBy | "model" | "human" | Who drew the links. Default "model": the details then say they are unchecked. |
