A connector chat whose sender holds talkback.channels gets the tool
send_message. It writes in the conversation, or as a new top-level
message in a channel that the owner listed on the binding (id, label,
approved; at most 10). The tool names no platform.
An unlisted channel is refused and the error lists the ones that are.
A listed channel that the owner did not approve needs the sensitive
talkback.new_channel for each message, so only a paired sender can use
it. The agent cannot add or approve a channel, so text it read in a page
or a file cannot widen where it writes.
Messages go through the outbox (rate limit and queue), with the size cap
and the mention breaking. Each attempt adds an audit row with channel,
kind, capability, length and a hash, never the text.
A trigger can report to an approved channel with delivery target
channel. The binding, the capability and the listing are checked again
when the run ends; any failure sends the notice to the Inbox.
LOCALAI_DISABLE_CONNECTOR_TALKBACK turns both off.
