-- Per-heartbeat mesh-activity time-series (SPEC MA3).
--
-- Append-only: one row per ingestor heartbeat that carries a `packets` count
-- (the merged RX+TX frames observed since the previous heartbeat, MA1/MA2).
-- Each ingestor's contribution is kept as its own rows rather than pre-summed,
-- so a packets/hour moving average can be computed across time, protocol, and
-- multiple ingestors per protocol (the read-side MAX aggregation, MA4). Rows
-- are pruned by the retention worker on `at`.
