Plans and credits
The unit
One credit is six cents of metered model spend at list price.
Quota is money, never a count
An "action" is not a unit of cost. Measured across the routing table, the cost of a delivered action varies about nineteen times, from under two cents to thirty. So the same "1,000 actions" costs between sixteen and three hundred dollars to serve, and a quota denominated in a count cannot bound cost of goods.
Quota is therefore enforced in money. Credits are a display projection, computed from the remaining allowance. They are derived, never stored: two stored numbers that must agree is how a billing system starts lying.
Pricing is per company, not per seat
Per-seat pricing would overcharge the solo founder who is the whole company, and would make a large customer ration the read-only viewers who should be watching the agents. Seat count drives the governance profile, never the invoice.
What is enforced today
Structural limits (members, departments, features) are enforced at gate 4. The money allowance and its overage path are enforced at gate 8.
Not yet enforced anywhere: retention windows, real-versus-simulated adapter gating, and the concurrency limit, because nothing schedules yet. The tier table is not a description of running behaviour for those three.
