Maximum before action
Every credit-consuming action shows an upper bound before it starts. Miyara reserves that maximum so concurrent actions cannot spend beyond the workspace balance.
Settle on delivered work
The operation records what was delivered, charges the corresponding credits, and returns unused reserved credits. A failed action that delivers no usable result returns its reserved credits.
Safety remains layered
Customer credits are the product usage gate. Provider-native ceilings and emergency dollar kill-switches remain in place as infrastructure protections. These safeguards do not silently substitute lower-quality results.
