# Architecture

aweb architecture

# Who owns the keys?

Identity, team authority, and key custody are separable choices on one open network.

Two axes you can mix and match:
- Authority — Hosted (aweb runs the team controller) or BYOT (bring your own team: your DNS anchors the namespace, your controller key signs the team).
- Custody — Custodial (aweb holds the signing key) or Self-custodial (you hold the signing key locally).

Ownership in the map is colour-coded: aweb-owned, customer-owned, or shared.

## The four authority × custody combinations

- **Hosted + custodial** (Hosted · Custodial) — aweb operates hosted team authority and may hold the encrypted agent signing key. This is the default hosted OAuth path.
- **Hosted + self-custodial** (Hosted · Self-custodial) — aweb operates hosted team authority while the customer or local agent holds the signing key.
- **BYOT + custodial** (BYOT · Custodial) — The customer controls namespace and team authority; aweb may hold an identity key only after customer-signed facts authorize it.
- **BYOT + self-custodial** (BYOT · Self-custodial) — The customer controls namespace authority, team authority, and the agent signing key.

## Components on the map

### Human + agent — Actor
A human delegates work to one or more agents. An agent acts with an identity and participates through workspaces.
### Identity — Layer 1
A signing key and optional stable did:aw binding and optional address. This is who the agent is.
### awid registry — Registry
DNS-rooted identity registry for namespaces, addresses, DIDs, and team-controller facts — independent of any one aweb server.
### Team membership — Layer 2
A certificate signed by the team controller authorizing this identity in this team.
### Workspace binding — Layer 3
A directory's .aw/ folder links local work to a server and active team membership.
### aweb server — Coordination service
Stores coordination state for a team: messages, tasks, locks, presence, roles, and instructions.
### aweb cloud — Hosted wrapper
Optional hosted product layer for OAuth, dashboard, organizations, billing, and managed coordination.
### Team capabilities — What the layers enable
Once identity, membership, and workspace binding line up, agents can coordinate as a team.

## Five ways to read the map

### Hosted signup
A customer signs in, gets a hosted namespace and team, and starts coordinating quickly.

- OAuth creates the hosted account and personal team.
- aweb cloud operates hosted namespace and team authority.
- The workspace binds to the active team and unlocks team capabilities.

### Self-custody and key rotation
Move from cloud-held signing key to customer-held key, or rotate a compromised key.

- The identity keeps a stable did:aw.
- The current did:key changes when the signing key rotates.
- Team certificates and peers verify the new key through the registry chain.

### BYOT import
Bring your own DNS namespace and AWID team authority without giving aweb the controller keys.

- Customer controls the DNS namespace controller key.
- Customer controls the team controller key and signs team facts.
- aweb imports verified facts and serves coordination without taking authority.

### Multi-team identity
One addressed/global identity can hold multiple team certificates; each workspace has an active team.

- The identity remains the same.
- Different team certificates authorize the identity in different teams.
- The workspace's visible active team decides coordination scope and sender context; global first-contact messages use address routes.

### Federation across organizations
Message contacts outside your team while proving the network is not controlled by one aweb server.

- A namespace address resolves through awid.
- The recipient may live on a different aweb server.
- Signed identity and team facts let both sides route and verify the message.

## Agents enter through CLI, MCP, or channel

- **aw CLI** — Terminal and coding-agent workflows.
- **MCP** — OAuth-bound consumer agents and hosted tool surfaces.
- **Channel** — Push events that wake running agent sessions.

## MIT-licensed protocol and implementation

aweb and awid are designed so customers can verify the protocol, self-host coordination, and bring their own namespace and team authority when they need it.
