Intake Composition Atlas

You can see the form.
You can't see the join.

A federal form looks small — a few fields, one purpose. But the same identifiers can be matched, shared, and fed into decisions across agencies, into a record you can't inspect or contest. This atlas maps that composition, one public receipt at a time.

What this refuses to claim: that any secret or unlawful use exists, or anyone's intent. It maps only what public records show — and labels every link by how sure we are:

Documented

A public record says the flow exists.

Authorized

A law permits it; no evidence it occurs.

Inferred

Composition makes it derivable.

Speculative

Incentive analysis only. Hidden by default.

Each case is a documented-path graphic. Toggle the weaker layers to see what's permitted, then what's possible — that delta is the finding.
What this is, precisely
Populations exposed to inferences and decisions composed outside their effective contestation surface. A typed, receipt-backed map of federal intake composition: every edge carries exactly one claim type and a citation to a public record. Doctrine — no edge without a receipt; signed is not witnessed; inferred edges show their derivation; no PII; public surfaces only; absence recorded as absence, not concealment. Sibling to the Grid Dependency Atlas. Method, receipts, and linter are in the repository.
