historical-only calculation path.
## Power-meter pipeline
The generic `power_meter` package collects configured ENLYZE meters into
TimescaleDB/PostgreSQL. The B2 example uses only verified UUIDs for machine,
energy total, active power total and grid frequency. Power-outage counting is
supported by schema/repository but remains unset until the real UUID is present
in local raw exploration data. Counter decreases start a new epoch and record
the new counter value as the increment; the first observation establishes a
baseline with zero increment. Optional phase power is stored as JSONB and does
not require L2. `report monthly` reads the database directly, writes
`<mount>/<meter>/<year>/<meter>_Powermeter_<YYYY-MM>.pdf`, and persists report
metadata independently of Grafana.
