xworkmate_bridge

This document records the current real deployment and runtime validation state for the XWorkmate ACP bridge stack.

Scope

roles/vhosts/xworkmate_bridge owns the public ingress and validation contract for xworkmate-bridge.svc.plus.

The private distributed bridge transport is managed by roles/vhosts/xworkmate_bridge_distributed_vpn and deployed through vpn-wireguard-over-vless.yml. That role provides wg-xwm, xray-wg-tproxy.service, and the VPN-only 172.29.10.0/24 bridge forwarders. This bridge role consumes the resulting distributed topology config; CN forwards tasks to the primary private endpoint, while the primary node keeps reverse task forwarding disabled.

The provider runtimes remain separate sibling roles:

• roles/vhosts/acp_codex
• roles/vhosts/acp_opencode
• roles/vhosts/acp_gemini
• roles/vhosts/acp_server_hermes

Real Deployment

The stack was redeployed with a real run, not dry-run, using the committed inventory from HEAD.

Command pattern:

tmp_inventory=$(mktemp)
git show HEAD:inventory.ini > "$tmp_inventory"
ansible-playbook -i "$tmp_inventory" deploy_xworkmate_bridge_vhosts.yml -l jp-xhttp-contabo.svc.plus
rm -f "$tmp_inventory"

Latest verified real deployment result:

• play recap: ok=91 changed=17 failed=0 unreachable=0

Token Source

INTERNAL_SERVICE_TOKEN was loaded from:

• accounts.svc.plus/.env

Deployment and verification used that token value from .env instead of requiring the shell session to be pre-exported.

Unified Authentication

The ACP entrypoints now reuse the same INTERNAL_SERVICE_TOKEN.

Applied areas:

• main bridge service: xworkmate-bridge.service
• Codex ACP bridge: acp-codex.service
• OpenCode ACP bridge: acp-opencode.service
• Gemini ACP adapter: acp-gemini.service
• Hermes ACP adapter: acp-hermes.service

Behavior after deployment:

• requests without Authorization: Bearer $INTERNAL_SERVICE_TOKEN are rejected
• requests with Authorization: Bearer $INTERNAL_SERVICE_TOKEN are accepted
• this playbook only defines and validates the shared ingress token path
• provider-specific authentication and ACP method compatibility are intentionally left to the individual runtimes
• the Codex runtime user is a role variable and defaults to ubuntu, so it can be changed from inventory if needed
• Gemini adapter is now also aligned to ubuntu home paths so it can reuse /home/ubuntu/.gemini/oauth_creds.json

Public Endpoints

App-facing endpoints:

• wss://xworkmate-bridge.svc.plus/acp: canonical WebSocket JSON-RPC runtime
• https://xworkmate-bridge.svc.plus/acp/rpc: HTTP JSON-RPC fallback for capabilities, routing, agent, multi-agent, OpenClaw gateway tasks, cancel, close, CI, and diagnostics
• https://xworkmate-bridge.svc.plus/api/ping: release and runtime health probe

OpenClaw task admission is configured in the generated bridge config.yaml from these role variables:

• xworkmate_bridge_openclaw_gateway_max_active defaults to 5
• xworkmate_bridge_openclaw_gateway_max_queued defaults to 20
• xworkmate_bridge_openclaw_gateway_queue_timeout defaults to 10m

Apple review / beta 工测可配置临时 BRIDGE_REVIEW_AUTH_TOKEN。该 token 与主 BRIDGE_AUTH_TOKEN 并行生效；清空 BRIDGE_REVIEW_AUTH_TOKEN 并重新部署或 reload/restart bridge 即可单独关停审核通道，不影响生产 token。

Non-contract routes:

• Provider-direct routes such as /codex, /opencode, /gemini, /hermes, and legacy ACP provider paths are not public APP contracts
• /gateway/openclaw is no longer an app-facing task submit route; OpenClaw tasks use /acp/rpc with routing metadata

Post-Deploy Verification

Without token:

• https://xworkmate-bridge.svc.plus/acp/rpc -> 401

With Authorization: Bearer $INTERNAL_SERVICE_TOKEN:

• wss://xworkmate-bridge.svc.plus/acp -> 101 Switching Protocols
• https://xworkmate-bridge.svc.plus/acp/rpc acp.capabilities -> 200
• https://xworkmate-bridge.svc.plus/acp/rpc xworkmate.routing.resolve -> 200
• https://xworkmate-bridge.svc.plus/acp/rpc OpenClaw session.start -> 200 with either success or structured provider failure

Bridge public root:

• https://xworkmate-bridge.svc.plus/ -> 200

Expected body:

• xworkmate-bridge is running

JSON-RPC AI Chat Task Validation

A real JSON-RPC chat task was executed with the prompt:

请只回复：AI chat task ok

Agent tasks use /acp/rpc or /acp with explicit routing metadata:

{
  "jsonrpc": "2.0",
  "id": "example",
  "method": "session.start",
  "params": {
    "sessionId": "example",
    "threadId": "example",
    "taskPrompt": "请只回复：AI chat task ok",
    "workingDirectory": "/root",
    "routing": {
      "routingMode": "explicit",
      "explicitExecutionTarget": "singleAgent",
      "explicitProviderId": "codex"
    }
  }
}

OpenClaw task submission uses the same JSON-RPC envelope at /acp/rpc, with routing.explicitExecutionTarget=gateway and routing.preferredGatewayProviderId=openclaw. Follow-up session.message for the same OpenClaw task also stays on /acp/rpc.

Current Operational Status

• ACP ingress deployment: validates /api*, /acp*, /artifacts/*, and /
• unified internal bearer token: required for protected endpoints
• bridge public root route: working
• legacy ACP provider Caddy fragments: removed from public ingress

Out Of Scope

The following issues may still need attention at the provider/runtime layer, but they are not defined as playbook responsibilities:

1. Remote Codex/OpenAI runtime authentication configuration used by codex-app-server
2. Gemini adapter protocol mapping for executable chat methods such as bridge session.start and session.message
