When the router sees a mention or DM on a messaging group that isn't wired
to any agent, it now escalates to an owner for approval instead of silently
dropping. Mirrors the existing unknown-sender approval pattern (ACTION-ITEMS
item 22).
Schema (migration 012):
- `messaging_groups.denied_at TEXT NULL` — timestamp set on deny so future
mentions stop escalating. ALTER TABLE ADD COLUMN, FK-safe (unlike the
rebuild that bit migration 011).
- `pending_channel_approvals` — PK on `messaging_group_id` gives free
in-flight dedup. One card per channel, no spam on rapid retries.
Router:
- New hook `setChannelRequestGate(mg, event) => Promise<void>`, invoked
from the no-wirings branch when the message was addressed to the bot
(isMention=true). Hook is fire-and-forget.
- Checks `mg.denied_at` before escalating — denied channels drop silently
and do not re-prompt.
- The two "no-wirings" branches (fresh auto-create and existing mg with
no agents) are consolidated into one escalation path that calls the
gate once. Without the module, behavior is log + record (no regression).
Permissions module:
- `channel-approval.ts::requestChannelApproval` — MVP picker: target
agent is `getAllAgentGroups()[0]`, card names it explicitly ("Wire it
to <Andy>?"). Approver via existing `pickApprover` + `pickApprovalDelivery`
primitives.
- Response handler: same click-auth pattern as sender-approval (clicker
must be the designated approver OR have admin privilege over the
target agent group).
- Approve defaults per the feature spec:
engage_mode = 'mention-sticky' for groups, 'pattern' + '.' for DMs
sender_scope = 'known'
ignored_message_policy = 'accumulate'
session_mode = 'shared'
DM vs group inferred from the original event's threadId (non-null →
group) because the auto-created mg has a placeholder is_group=0 until
the adapter fills it in.
- Triggering sender is auto-added to agent_group_members so sender_scope=
'known' doesn't bounce the replayed message into a sender-approval
cascade.
- Deny: stamps messaging_groups.denied_at, clears pending row.
- Failure modes — no owner, no agent groups, no reachable DM — log and
drop without creating a pending row, letting a future attempt try
again (same as sender-approval).
9 new integration tests cover every branch: mention triggers card, DM
triggers card, dedup, approve creates correct wiring + admits sender +
replays, approve-on-DM uses pattern/'.' defaults, deny sets denied_at
and future mentions drop silently, unauthorized clicker rejected,
no-owner drops, no-agent-groups drops.
168 tests pass (was 159; +9).
