DL-256

The Linear return path is a dumb link (Option B, Matt 2026-08-25): on created the responder emits one thought plus an externalUrls “Open in Compass” deep link to the resolved Manager’s home channel and nothing else — NO activity relay, NO settle observation, NO Linear session-lifecycle machine. One Linear session is NOT forced 1-1 to a comms topic; the prompt lands in an issue-named topic (persisted in a new linear_agent_sessions table) delivered as @linear-authored deliver-rail messages deduped by PostAsAccount’s client_request_id on the Linear-Delivery UUID, but the deep link targets the home channel. Option C (coarse one-way status) is the ratified follow-up; Option A (full bidirectional relay) is off-table until Linear’s activity vocabulary is configurable

Status: Active (Matt, 2026-08-25)
