Rules the system enforces

The connector uses local linked-device WhatsApp Web and does not turn the CRM into a WhatsApp Business API client.
Normal administrators never need to reveal connector credentials or access authentication directories.
Account access, verified customer ownership and protected download checks are enforced server-side.
The private connector is intended for 127.0.0.1 and not for public Internet exposure.

How to confirm it worked

The requested action completes without a permission, validation, connector or native CRM error.
The selected account or conversation shows the expected state without changing another account’s data.
Where the action creates evidence, confirm the message, native record, verification event, portal history or audit entry is present.

Security, privacy and troubleshooting checks

Never expose connector tokens, loopback ports, authentication directories or raw customer verification replies.
Use the supported Connections, Access Control, Settings and Audit Trail pages rather than editing runtime or database records directly.
If the expected control is missing, verify both native capability and per-account permission before treating it as an installation fault.
