# 03-DESIGN / 01-to-be

The mesh being built toward. Every statement here traces to a record in
[`02-DECISIONS/`](../../02-DECISIONS/); nothing arrives by drafting.

A document here describes an intention. What currently runs is in
[`00-as-is/`](../00-as-is/), and the two are never merged — when something ships, the as-is
document is written and this one's status becomes `implemented`.

## Not yet written

- **The eight bounded contexts.** [ADR 0015](../../02-DECISIONS/0015-mesh-brokers-nodes-host-agents-think.md)
  decides the decomposition; the per-context specifications do not exist yet. The work
  breakdown says in what order they are needed.
- **Domain grouping outside the core.** [ADR 0017](../../02-DECISIONS/0017-modules-outside-the-core-are-grouped-by-domain.md)
  settles the principle and explicitly does not settle the domain list. That is a research
  effort, not a design document, until it concludes.
