The layer rule
Layer 3.5 is the protocol for sharing context.
An entity curates what may leave. Another entity may receive it. The exchange is deliberate. That is the fairness rule for the use of the information, and the governance for privacy and for the record staying with its holder.
Why the crossing has its own layer.
A household, a firm, and a community each hold knowledge they can use inside their own walls. Collaboration starts when one of them needs a piece of what another knows. A general workspace solves that by opening the account. The agent then leaves with the tax return, the clinical note, and the story that was never offered.
Layer 3.5 is the external-facing layer built for that moment. It sits between the organization and the public atmosphere. Inter-entity work uses it: a clinician receives the record you marked, a partner receives the protocol a firm curated, a council receives a position written for the hearing. Society-scale work is the same rule repeated. Many edges, each held by the entity that curated it, are how a society shares context without emptying every vault.
It starts with the organized record.
An agent produces economic output from context that is fit to send. The fitness is the earlier work. You place the record in Boundless. You decide what connects, what is still private, and what may be shown. The product of that decision is an artifact on Layer 3.5: traceable, authorized, and fit for another entity to receive.
The artifact becomes shareable by being marked. The private layers stay where they are. A subscription from another entity arrives as a signal. It is a source. It becomes this entity's knowledge only after this entity cements it. The sender's inner record stays with the sender.
Three kinds of work on the same band.
Advocate
A delegate agent carries a marked position outward and speaks for it. A filing, a submission, or a public thread can use that artifact. The opinion is the one you settled in the vault.
Be heard
Being heard requires a record the other party can hold. Layer 3.5 is prepared for that receipt. You participate with context that was organized before the conversation, so the agent amplifies a judgment you still practise.
Consult and contribute
Consulting, in this form, is a subscription to knowledge bounded by the Layer 3.5 mark. A resident agent works on that band for the subscriber. You contribute the curated piece. You keep the core.
Where each layer sits.
Layers 1 to 3 are degrees of a private circle. Layer 4 is public. Layer 3.5 is the curated band a delegate may carry, so one entity can share context with another. The orange rule marks that band.
