POST /admin/set_channel_welcome endpoint — set channel welcome messages
from scripts without running slash commands manually in each channel.
Requires system admin. Rejects non-open channels early with a clear
error rather than silently storing a message that will never fire.
/welcomebot welcome command — re-shows the current channel's welcome
as an ephemeral visible only to you. Recovery path for users who missed
the welcome on join. Works in any channel with a message configured.
ChannelWelcomeAutoJoinDelaySeconds setting — configurable delay before
sending the channel welcome ephemeral (default 5s). Increase if users
report the welcome appearing before the channel has fully loaded.

Bug Fixes

Fixed double delivery: plugin-initiated channel adds were firing the
ephemeral twice — once from joinChannel and once from the
UserHasJoinedChannel hook. The hook now skips plugin-initiated joins
(actor == nil); joinChannel delivers directly.
Fixed sysadmin check: strings.Contains on user.Roles replaced with
HasPermissionTo — the correct API that handles custom roles and
permission grants rather than substring matching on a role string.
Fixed nil panic: atomic.Value.Store(nil) on missing WelcomeMessages
config now normalized to an empty slice before storing.
Fixed nil panic: GetTeamMember returning (nil, nil) caused err.Error()
to be called on a nil error in the button-action HTTP handler.
Fixed channel type enforcement: all code paths now use
!= ChannelTypeOpen, covering private, direct, and group channels
consistently. Previously some paths only blocked ChannelTypePrivate.

Known Limitations

Channel welcome ephemerals are not stored server-side. On rejoin (user
left and rejoined a team), the client rehydrates from server state and
the welcome is gone before the page renders. Run /welcomebot welcome
to re-show it at any time.
