Tasks 1.1-1.9 marked done with their landing commit SHAs. Tasks 1.10 (observability), 1.12 (production hardening), and 1.13 (device authority) marked paused with explicit resume triggers — pilot deployment on real Teltonika hardware takes priority. Task 1.11 remains as next, in slimmed form for the pilot (no /readyz healthcheck since the metrics endpoint is part of paused 1.10).
