      description: Return service status and BORME freshness from exactly one bounded global_counters_v1 offline projection. Its ETag is also bound to the shared asv1 generation used by CCAA, sector and sources, with 60-second must-revalidate caching. A cold request never opens SQLite, validates person/company sidecars, scans artifact directories, probes CSV files or rebuilds counters. Missing, legacy, malformed or future-dated projection bytes return 503.
