@ours.network/connector

Reactivity connector for any webhook + shell-tool-calling harness to receive ours.network messages, where each subagent binds its own ours identity (multi-identity). Generalized from the a2adapt/Hermes bridge. Zero runtime dependencies — it drives ours-mcp proxy over stdio (raw JSON-RPC).

Design — N parallel (observe → wake → drain) triples, one per identity

1. OBSERVE (connector-watch.sh): one ours-mcp watch <id> per identity (non-binding, non-draining) → on each line, poke the gateway webhook with the identity tag. Never binds or drains.
2. WAKE (webhook): HMAC-SHA256-signed POST carrying the event (as an X-GitHub-Event header and an event_type body field — the two channels Hermes matches routes on) plus {"identity":"<id>"}. The connector defines the contract (config-overridable); the harness gateway matches.
3. DRAIN (per-identity sole-drainer): the gateway routes the wake to the subagent bound to <id>; its proxy calls get_messages. Sole-drainer holds per identity by construction — ours binding is exclusive per identity, so exactly one drainer per inbox. N identities = N sole-drained inboxes on ONE shared ours daemon.

Delivery hardening

• Drain-on-(re)connect per identity — unconditional wake at startup + after each watch reconnect.
• Poke retry/backoff per identity — never silently drop the only wake.
• Missed-wake backstop (gateway-side, per identity) — periodic non-consuming list_incoming → drain only if unread. Lives in the gateway (which owns each binding), not the watcher.

Webhook contract (config-overridable, both ends match)

POST  <CONNECTOR_WEBHOOK_URL>
body  {"event_type":"<CONNECTOR_EVENT>","event":"<CONNECTOR_EVENT>","identity":"<id>"}
hdr   X-GitHub-Event: <CONNECTOR_EVENT>            # event name, the way Hermes matches routes
hdr   X-Hub-Signature-256: sha256=<hex HMAC-SHA256(body, CONNECTOR_HMAC_SECRET)>
reply 200 accept · 401 bad signature · 400 unknown identity

Wakes are coalesced per-identity. The reference gateway refuses to start unless CONNECTOR_HMAC_SECRET is set to a non-default value.

Usage

export CONNECTOR_IDENTITIES="AgentA AgentB AgentC" \
       CONNECTOR_HMAC_SECRET=... \
       CONNECTOR_WEBHOOK_URL=http://localhost:8644/webhooks/ours-wake
ours-mcp start                          # one shared daemon for all identities
node connector-identity-setup.mjs       # create root + all identities
bash connector-watch.sh                 # per-identity watchers (supervise; self-reconnects)
# gateway: adapt connector-reference-handler.mjs — route wake.identity to that subagent's loop

Validated

• Single-identity: watch → HMAC-poke → 202 → sole-drainer drained a real message; bad-sig → 401 (no crash).
• Multi-identity (AgentA + AgentB): each wake routed to the correct identity's drain, no cross-draining.
