channel-extension

From the author

Use when adding a new messaging channel to Tel-Agent or changing an existing one — a transport under api/channels/, its official extension manifest, its settings card, tests, health and docs. Covers the file checklist, the two inbound shapes (dial-out and the public door), the credential and signature rules that are not negotiable, the declarative setup descriptor the generic card draws from, and the test shape every channel ships with.
