Admin Power Users

Engagement / power-user view from tool_call_events (the real per-call log; call_count is summed, not row-counted). Two cuts: • months — per calendar month: active machines + how many cross each usage threshold (>10 calls per active day on average, and >50 / >100 / >500 total calls in the month). • tiers_30d — machines bucketed by total calls in the last 30 days, each with the top tools that tier actually uses (summed call_count). 'User' = machine_id (tool calls key on the machine, not the account). Test/probe machines excluded.
