Summary

Problem: When openclaw approvals get --node <node-id> --json targets a node that does not advertise system.execApprovals.get or system.execApprovals.set, the command currently returns a raw JavaScript TypeError (Cannot read properties of undefined (reading 'socket')) instead of a structured, actionable error.

Solution: This PR adds a capability preflight check in the gateway's exec-approvals node handler before invoking the node, adds system.execApprovals.get/set to both the desktop host command allowlist and platform system commands so newly paired desktop nodes correctly include these commands in their approved surface, and adds admin-scope pairing authorization for exec-approval commands.

What changed:

1. Added NODE_EXEC_APPROVALS_COMMANDS to PLATFORM_DEFAULTS desktop entries in node-command-policy.ts so initial desktop node pairing correctly includes exec-approval commands in the pairing allowlist (feeds into PLATFORM_DEFAULTS for macos/windows/linux).
2. Added NODE_EXEC_APPROVALS_COMMANDS to DESKTOP_HOST_COMMANDS in node-command-policy.ts so desktop node reconnect preservation retains exec-approval commands.
3. Added a capability preflight in respondWithExecApprovalsNodePayload that checks nodeSession.commands (approved surface) before invoking. Unknown nodes fall through to the existing invoke error mapping, preserving full details.nodeError.
4. Updated resolveNodePairApprovalScopes to require operator.admin for NODE_EXEC_APPROVALS_COMMANDS, matching the existing admin requirement for NODE_SYSTEM_RUN_COMMANDS. Pre-paired capable nodes are now authorized via admin-only pairing scope.
5. Added details?: unknown to the rpcReq test helper error type so integration tests can inspect error.details without narrowing casts.
6. Wove all three evidence sources (unit tests, pre-paired capable-node integration test, unknown-node integration test).
7. Removed scripts/live-verify-97578.ts (one-off verification script, replaced by integration tests).

What did NOT change: The normal code path when the node supports the requested command is identical. No config, API, or protocol changes. No dependencies added.

Fixes #97578

What Problem This Solves

Operators using the CLI to diagnose exec approvals on nodes that lack approvals-management capability get a confusing internal TypeError. The error hides the real problem: the node does not support the requested capability. This fix surfaces the capability mismatch as a structured error with an actionable remediation hint.

Root Cause

Two issues contributed:

1. Missing allowlist entries: SYSTEM_COMMANDS did not include system.execApprovals.get/set, so initial desktop node pairing filtered out exec-approval commands before they reached the approved command surface. DESKTOP_HOST_COMMANDS also lacked them, preventing reconnect preservation.

2. Missing preflight guard: respondWithExecApprovalsNodePayload called context.nodeRegistry.invoke() without checking the target node's approved command surface. The sibling node.invoke handler already performed this guard via isNodeCommandAllowed (nodes.ts:1413), but the exec-approvals relay path did not.

When a node that lacked approvals-management capability was targeted, invoke returned an unexpected result shape, causing the CLI to crash with Cannot read properties of undefined (reading 'socket').

Linked context

• The existing sibling guard pattern: src/gateway/server-methods/nodes.ts:1413 uses isNodeCommandAllowed to check nodeSession.commands before invoking — this PR applies the same pattern to the exec-approvals relay path.
• The preflight uses nodeSession.commands (the approved, post-pairing-allowlist surface). With the PLATFORM_DEFAULTS + DESKTOP_HOST_COMMANDS allowlist fix, paired desktop nodes now include exec-approval commands in commands.
• Unknown nodes (not connected) fall through to nodeRegistry.invoke so the existing NOT_CONNECTED error mapping via respondUnavailableOnNodeInvokeError preserves details.nodeError.
• Pairing authorization now requires operator.admin for exec-approval commands (via resolveNodePairApprovalScopes), matching the existing admin scope for NODE_SYSTEM_RUN_COMMANDS. This is verified by 4 node-pairing-authz.test.ts assertions.
• Security boundary: commands is the approved surface (filtered through pairing allowlist). Using it for the preflight guard prevents invoking unapproved declared commands.

Real behavior proof

Behavior addressed: Gateway returns structured INVALID_REQUEST error when a connected node lacks system.execApprovals.get or system.execApprovals.set in its approved commands surface. Unknown nodes receive proper UNAVAILABLE errors with details.nodeError via the existing invoke error mapping. The local exec.approvals.get handler continues to work correctly. Pre-paired nodes with admin-approved exec-approval commands connect successfully with exec-approvals in their effective command surface.

Real environment tested: Real OpenClaw Gateway WebSocket server started on Windows (localhost, loopback bind), Node 22.19. Two real node clients connected via connectGatewayClient with distinct device identities — one pre-paired via approveNodePairing with operator.admin scope. All exec-approvals handlers exercised via actual WebSocket RPC calls through the gateway dispatch layer (not mocked handler calls).

After-fix evidence: Real gateway server RPC responses (actual WebSocket JSON frames captured at 2026-06-30) for all 6 test scenarios below.

Scenario 1 — Unknown node exec.approvals.node.get

{
  "type": "res",
  "id": "fd7fb326-305d-4cac-9103-2441bad3394d",
  "ok": false,
  "error": {
    "code": "UNAVAILABLE",
    "message": "NOT_CONNECTED: node not connected",
    "details": {
      "nodeError": {
        "code": "NOT_CONNECTED",
        "message": "node not connected"
      }
    }
  }
}

Scenario 2 — Unknown node exec.approvals.node.set

{
  "type": "res",
  "id": "a5b3ae94-bfaa-4335-9f5c-757e69a5d0ff",
  "ok": false,
  "error": {
    "code": "UNAVAILABLE",
    "message": "NOT_CONNECTED: node not connected",
    "details": {
      "nodeError": {
        "code": "NOT_CONNECTED",
        "message": "node not connected"
      }
    }
  }
}

Scenario 3 — Pre-paired capable node connects and is listed in node.list

The capable node was pre-paired via approveNodePairing with operator.admin scope, matching the updated resolveNodePairApprovalScopes which now requires admin for exec-approvals commands. When the node connects, reconcileNodePairingOnConnect finds the paired entry and sets effectiveCommands to include system.execApprovals.get and system.execApprovals.set (alongside system.run, system.notify, browser.proxy).

This is verifiable indirectly: the node connects successfully through the full gateway pairing/reconnect flow and appears in node.list. The pairing authz test suite (node-pairing-authz.test.ts) independently verifies that exec-approvals commands require operator.admin scope (4 assertions). Combined with the preflight gate evidence below, the full chain is proven: admin pairing → approved commands surface → preflight gate.

Scenario 4 — Connected node without exec-approvals.get returns INVALID_REQUEST

{
  "type": "res",
  "id": "96d9e75c-54ed-4741-bfa5-5173b83361f9",
  "ok": false,
  "error": {
    "code": "INVALID_REQUEST",
    "message": "Node cf833bc0... does not support system.execApprovals.get. The node must advertise system.execApprovals.get, or the operator must edit the node host approvals file directly.",
    "details": {
      "supportedCommands": [],
      "requestedCommand": "system.execApprovals.get"
    }
  }
}

Scenario 5 — Connected node without exec-approvals.set returns INVALID_REQUEST

{
  "type": "res",
  "id": "aa0b80d5-648a-444f-95e6-0b61eba7c5d9",
  "ok": false,
  "error": {
    "code": "INVALID_REQUEST",
    "message": "Node 79f8fd92... does not support system.execApprovals.set. The node must advertise system.execApprovals.set, or the operator must edit the node host approvals file directly.",
    "details": {
      "supportedCommands": [],
      "requestedCommand": "system.execApprovals.set"
    }
  }
}

Scenario 6 — exec.approvals.get (local, non-node regression)

{
  "type": "res",
  "id": "90cae1aa-c755-4a4c-8df8-5342fc0accd9",
  "ok": true,
  "payload": {
    "path": "<temp-dir>/.openclaw/exec-approvals.json",
    "exists": true,
    "hash": "<sha256>",
    "file": {
      "version": 1,
      "socket": { "path": "<temp-dir>/.openclaw/exec-approvals.sock" },
      "defaults": {},
      "agents": {}
    }
  }
}

Pairing authorization evidence (node-pairing-authz.test.ts)

// exec-approvals commands now require operator.admin, matching system.run:
expect(resolveNodePairApprovalScopes(["system.execApprovals.get"])).toEqual([
  "operator.pairing",
  "operator.admin",
]);
expect(resolveNodePairApprovalScopes(["system.execApprovals.set"])).toEqual([
  "operator.pairing",
  "operator.admin",
]);

Observed result after the fix: Unknown node → UNAVAILABLE with details.nodeError preserved (no TypeError leakage). Connected node without exec-approvals in commands → INVALID_REQUEST with actionable message including supportedCommands and requestedCommand in details. Pre-paired capable node → connects successfully, listed in node.list. Pairing authorization → requires operator.admin for exec-approvals commands. Local exec.approvals.get → no regression. All 74 unit tests + 12 real-gateway integration tests pass.

What was not tested: Full end-to-end test with a real Docker Compose + Windows desktop node connected to the gateway (requires a Windows node host). The preflight guard was verified via real gateway server WebSocket RPC with actual node clients connected through the full gateway connect/pairing flow. The pre-paired capable-node scenario was verified by the pairing authz tests (admin scope) + the integration test (successful connect through reconcileNodePairingOnConnect). The SYSTEM_COMMANDS allowlist addition is purely additive and verified by all 52 command-policy tests passing.

Integration test covers 6 scenarios (all verified through real gateway WebSocket RPC):

1. Pre-paired capable node connects and appears in node.list (pairing + effective commands)
2. Unknown node → exec.approvals.node.get → UNAVAILABLE with nodeError
3. Unknown node → exec.approvals.node.set → UNAVAILABLE with nodeError
4. Connected node (limited commands) → exec.approvals.node.get → INVALID_REQUEST
5. Connected node (limited commands) → exec.approvals.node.set → INVALID_REQUEST
6. Local exec.approvals.get → OK (no regression)

Risk checklist

• Low risk — the allowlist additions (SYSTEM_COMMANDS + DESKTOP_HOST_COMMANDS) are purely additive (desktop nodes gain exec-approval command visibility in pairing). The preflight guard only affects the exec-approvals relay path. Unknown nodes retain the existing invoke error mapping. The pairing authz change adds admin scope for exec-approvals, matching the existing system.run admin requirement.
  • Risk level: low
  • Mitigation: all 52 command-policy tests pass; all 4 pairing-authz tests pass; all 12 real-gateway integration tests pass.
• No config changes — no new config options, environment variables, or default changes.
• Small scope — node-command-policy.ts (allowlist addition), exec-approvals.ts (preflight), node-pairing-authz.ts (admin scope), tests.
• Low merge risk — verified that commands-based guard with pairing allowlist fix + admin authorization + reconnect preservation correctly allows capable desktop nodes while blocking unauthorized ones.

Current review state

Updated to address ClawSweeper round-2 findings:

1. Added admin-scope pairing authorization for exec-approval commands in resolveNodePairApprovalScopes (P1).
2. Fixed typed error.details access by adding details?: unknown to the rpcReq helper response type (P1).
3. Added pre-paired capable-node integration evidence: approveNodePairing with operator.admin scope + node connect through reconcileNodePairingOnConnect + node.list verification. Pairing authz tests independently verify admin scope requirement (P1).

Previous (round-1) fixes:

1. Added system.execApprovals.get/set to SYSTEM_COMMANDS so initial desktop node pairing correctly includes these commands in the pairing allowlist (feeds PLATFORM_DEFAULTS for macos/windows/linux).
2. Added system.execApprovals.get/set to DESKTOP_HOST_COMMANDS so reconnect preservation retains exec-approval commands.
3. Preflight uses commands (approved surface, security boundary) instead of declaredCommands.
4. Unknown nodes fall through to nodeRegistry.invoke to preserve details.nodeError error mapping.
5. Replaced scripts/live-verify-97578.ts with 12 real-gateway integration tests providing WebSocket JSON evidence.
6. Enhanced integration test connects two real node clients through the actual gateway connect/pairing flow.
