Simulate Q get Putative Batch Root

InductiveMerkleTree.simulateQ_getPutativeBatchRoot

Run Steps Async empty trivial eq

Interaction.Concurrent.runStepsAsync_empty_trivial_eq

Plain-language statement

Under the empty env alphabet (EnvAction.empty Unit) and the trivial env scheduler (always processTick), runStepsAsync reduces to ProcessOver.runSteps with the env state pinned to () and a constant processTick trace. This is the operational core of the sync-recovery story: it factors the async engine into the synchronous ProcessOver.runSteps...

Is Per Index Query Bound to Worst Case Cost Bound unit sum

IsPerIndexQueryBound.toWorstCaseCostBound_unit_sum

Plain-language statement

If main makes at most qb i queries to each oracle i, then its total query count (under the unit cost model) is at most ∑ i, qb i on every execution path.
