STOP is honoured
A recipient who texts STOP is opted out of the line, and a send to them is refused until they text START.
CommandAGI · commandagi.com/for/text-messages
A line's texts and calls are a plain file a correspondent in your Drive. An outbound text is written before it is sent, and what the provider answered follows it.
A text
A reply never implies delivery. Only the provider's status record says what happened, and a lost answer is unknown.
From CommandAGI's demo account user-mock-omar. The reply was queued; the provider said the handset was off. The numbers reach no one.

The rules
Lines are for business conversation. A2P 10DLC brand and campaign registration is built in, and its fees are held before the provider is asked.
A recipient who texts STOP is opted out of the line, and a send to them is refused until they text START.
An MMS's media are copied into the Drive beside the conversation. A contact card is a content-addressed .vcf.
No line has sent a text through a live provider: the route tests run the real routes with a fake only at the provider's edge (docs/phone.md § verified).
An agent can answer your customers' texts under a grant with a daily bound.
