      description: 'Return the most recent platform benchmark row (largest period_start < today). Platform-GLOBAL: every team reads the same weekly row. No parameters. Use to compare an account or fleet against the market (acceptance rate, reply rates) and to calibrate safe daily ceilings by cohort. Pair it with linkedin-account-snapshots / linkedin-accounts / *.metrics for the per-account numbers to compare against. Every metric lives in the group_1 / group_2 / group_3 JSON blobs; dereference the specific path per MARKET_BENCHMARKS.md. NOT for a single account''s current numbers (linkedin-accounts / -snapshots), live limit utilisation (linkedin-account-smart-limits), a specific quota hit (linkedin-account-quota-hits), or historical trends (internal-only). Cold start returns 404 no_benchmark_published.
