"""Slack team-qualified addressing for managed relay (slack-relay-spec §8/§9).
|
|
|
|
A single owner can be in several Slack workspaces at once, so a bare channel id
|
|
(`C…`) is ambiguous — a `U…`/`C…` only means something inside its `team_id`.
|
|
Managed-relay targets therefore carry the team: the reply handle's chat_id is
|
|
`"{team_id}/{channel}"`.
|
|
|
|
Encoding note: the reply-target grammar is colon-delimited
|
|
(`platform:chat_id[:thread]`, see base.parse_target), so we join team+channel
|
|
with `/` — colon-free — to stay inside that grammar unchanged. `slack:T012345/C0123`
|
|
is the wire form of the spec's conceptual `slack:T012345:C0123`. Manual
|
|
Socket-Mode targets (single workspace) keep the bare `slack:C0123` form.
