Why: The remaining open items (API-key SSE closure, cross-instance redeem backoff, U7 atomic bootstrap/create, CLI credential delivery) landed in Backend #192; Dev pins it and closes the contract leftovers. Evidence: Backend #192 CI success at head bc1e0a3 (GATE); composite CI on this PR re-runs the suite incl. test-pg (GATE). Impact: backend pin cfb8308; contract leftover section now records all items closed; task card H1-H6 requirement table. Refs: Backend #192; docs/svc-deploy/2026-10-13-login-recovery-contract.md.
