The network
This is a reference site for a primitive, which means its most important property is what it refuses to hold. Five other sites depend on the twin idea. Each should be able to state it in three lines and link here, and this site should not restate what they own.
1. What this site owns
The definition
A system with properties, behaviours, functions, inputs and outputs, and the doorway from the model to reality. The primitive →
The discipline
Everything has to exist; connectedness is a fact; an unconnected twin is a tracked air gap. Read →
The broker, and the ruling
The execution broker on its own terms, and the naming decision that keeps the word usable. Read →
2. The boundaries, one line each
| Site | Relationship |
|---|---|
| twins.sgit.ai | Owns the primitive: definition, discipline, actors, the broker, the naming ruling |
| risks. / standards. | Own the grounding ladder and the regulation graph. This site owns the Twin rung and the hooks-and-coverage idea inside it. Each states the other in three lines |
| nhi. | Owns the identity-twin visualisation play; links here for the primitive |
| sg-compute. | Ships the S3 container and the vault specs; this site explains why the container is a twin |
| graphs. | Owns meaning-through-connectivity. This site owns what happens at the graph's edge, which is where that rule would otherwise run out |
| skills. | The naming-drift lesson is shared: its diverging-duplicate exhibit and this site's collision are the same finding by two routes |
| pki. | Owns agent identity and mandate, and its own execution-broker page. This site owns the twin the broker acts for; the credential design is theirs |
| riskmandate.ai | Commercial. References this site; is not referenced by it |
The pattern the estate already uses for the grounding ladder is the pattern here: one owner, many referrers, three lines and a link rather than a restatement. A restatement is a copy, and copies drift unless something checks them.
3. For agents
Two machine-readable summaries are published and kept in step with the site by the release gate:
- /llms.txt — the site's own summary: the definition, the build state, the ruling, and where each idea is owned.
- /llms-full.txt — the long form, including the full quotation set this site is built from.
The source documents are fetchable at stable constructed paths: /briefs/<filename>.md. That is a promise rather than an accident. The documents →
