Resolves the original block policy, not the current subscription's preferred source.
Checks active account/scope, caller permission, original tariff eligibility and supplier capacity. Handed a copy of the run as the store holds it when asked: an allocation link this class has just recovered is on it.

media duration. A never-dispatched run still needs a positive dispatch fence under the owner lock.
A kill request, terminal state, elapsed lease or missing worker is not positive evidence.
Return false fence flags while termination or final usage remains unknown. Handed a copy of the run as check is.
The manager's run store, where each run's snapshot, reservation link and settlement intent are persisted.
The compound credit store a cash-funded run's hold is reserved and settled in.
Host checks authority and capacity, while this class owns branch selection and ledger mechanics.
