Browser: returned authorization link opened real Linear consent; Approve led to https://linear.app/oauth/authorize login page.

NOT VERIFIED: token exchange, authenticated Linear tools, Claude provider, native clients, remote callback forwarding. No external account available; Claude unauthenticated.

After reconnect: orchestrator_capabilities returned successfully through the same provider thread; final response 34124-followup-ok.

Blacksmith: 75 focused service/handler/Claude-wire tests passed; 10 Codex MCP status cases passed.
