Usage for this workspace

Runs that were billed this period, by tier, with what they cost. totals.charged_cents is exactly the sum of these amounts — no other number has to be subtracted to arrive at it (E2E2-07).

Trial-covered runs, listed apart from the charged ones so "$0.00" reads as "included" rather than as "free by accident".

Runs an operator grant comped (0041), listed apart from the charged ones and NOT included in totals.charged_cents. Absent when this account has none.

Licensed-article spend (rung LT), at cost, from the fetch lane's own source ledger — NOT from usage_events and NOT part of totals. The two ledgers are separate on purpose: one is what this workspace was charged, the other is what a vendor charged us for a page, and summing them would double-count. All zeros when nothing was licensed, which is the shipping state.
