# CommunicationOS SMS channel

This package owns the canonical Twilio SMS channel adapter for
CommunicationOS. It supports signature-verified inbound form webhooks,
provider-backed outbound delivery, normalized ecosystem events and receipts,
and explicit provider-retention behavior.

The adapter uses an explicit Node-compatible build profile, including Bun server
hosts. Its credential and webhook boundary does not advertise a browser export
condition. Existing package entry points and provider contracts remain unchanged.

## Ecosystem composition

Use `createTwilioSmsEcosystemAdapter` from
`@lssm-tech/integration.communication-channel-sms/ecosystem-adapter` when
composing the current CommunicationOS ecosystem port. The adapter requires an
injected `SmsProvider`, an E.164 sender number, and the Twilio auth token used to
verify inbound signatures.

Managed connections store only an opaque credential reference. The resolved
secret document is expected to contain:

```json
{
  "network": "sms",
  "provider": "twilio",
  "accountSid": "...",
  "authToken": "...",
  "fromNumber": "+..."
}
```


The managed API accepts only `application/x-www-form-urlencoded` payloads with
an `X-Twilio-Signature` that verifies against the exact callback URL. The
managed worker rejects other providers or incomplete credential material.

Local conformance is not live provider qualification. Production activation
still requires consent and opt-out enforcement, credentialed callback/send
tests, delivery-status reconciliation, and an accepted Runtime Node effect
path.
