GAO150 Facebook Groups — installable-node prototype (MOCK ONLY)

Status: development prototype; not staging-qualified; not approved for production or live Facebook use.

This package is isolated at C:\Antigravity\n8n-nodes-gao150-facebook-dev-20261018\n8n-nodes-gao150-facebook-node. The canonical offline contract repository was copied to the parent workspace without its Git metadata; the canonical repository was not modified.

Safety properties

• All eight operations use deterministic synthetic fixtures.
• No credentials class or credential UI exists.
• No HTTP, browser, GraphQL, Facebook or Meta transport exists.
• No operation can send a join request, publish a post, or publish a comment.
• Every result declares mock=true, mode=MOCK_ONLY, liveIntegrationEnabled=false, and executionEnabled=false.
• No dev, release, publish, staging install or production install is part of this task.

Commands

• npm install — install development dependencies only in this isolated package workspace.
• npm run build — official n8n node CLI build.
• npm run lint — official node linter.
• npm run test:mock — deterministic synthetic fixture tests against the built output.

Build success and local mock tests do not establish compatibility with the remote n8n instance. Before staging, the Owner must designate an isolated instance, verify its exact version/runtime and rollback, and complete the applicable STG gates.
