Gateway-owned pairing (Option B)
In Gateway-owned pairing, the Gateway is the source of truth for which nodes are allowed to join. UIs (macOS app, future clients) are just frontends that approve or reject pending requests. Important: WS nodes use device pairing (rolenode) during connect.
node.pair.* is a separate pairing store and does not gate the WS handshake.
Only clients that explicitly call node.pair.* use this flow.
Concepts
- Pending request: a node asked to join; requires approval.
- Paired node: approved node with an issued auth token.
- Transport: the Gateway WS endpoint forwards requests but does not decide membership. (Legacy TCP bridge support is deprecated/removed.)
How pairing works
- A node connects to the Gateway WS and requests pairing.
- The Gateway stores a pending request and emits
node.pair.requested. - You approve or reject the request (CLI or UI).
- On approval, the Gateway issues a new token (tokens are rotated on re‑pair).
- The node reconnects using the token and is now “paired”.
CLI workflow (headless friendly)
nodes status shows paired/connected nodes and their capabilities.
API surface (gateway protocol)
Events:node.pair.requested— emitted when a new pending request is created.node.pair.resolved— emitted when a request is approved/rejected/expired.
node.pair.request— create or reuse a pending request.node.pair.list— list pending + paired nodes.node.pair.approve— approve a pending request (issues token).node.pair.reject— reject a pending request.node.pair.verify— verify{ nodeId, token }.
node.pair.requestis idempotent per node: repeated calls return the same pending request.- Approval always generates a fresh token; no token is ever returned from
node.pair.request. - Requests may include
silent: trueas a hint for auto-approval flows.
Auto-approval (macOS app)
The macOS app can optionally attempt a silent approval when:- the request is marked
silent, and - the app can verify an SSH connection to the gateway host using the same user.
Storage (local, private)
Pairing state is stored under the Gateway state directory (default~/.clawdia):
~/.clawdia/nodes/paired.json~/.clawdia/nodes/pending.json
CLAWDIA_STATE_DIR, the nodes/ folder moves with it.
Security notes:
- Tokens are secrets; treat
paired.jsonas sensitive. - Rotating a token requires re-approval (or deleting the node entry).
Transport behavior
- The transport is stateless; it does not store membership.
- If the Gateway is offline or pairing is disabled, nodes cannot pair.
- If the Gateway is in remote mode, pairing still happens against the remote Gateway’s store.
