Constant BUDGET_BURST_MICRO_TOKENS 

const BUDGET_BURST_MICRO_TOKENS: u64 = _; // 32_000_000u64

Token-bucket capacity: 32 hedges.

The bucket’s shape, not an operational lever: the tuning lever is persist_blob_hedged_get_budget_ratio and the kill switch is persist_blob_hedged_get_enabled. NOTE: because the bucket starts full, budget_ratio = 0 still permits ~32 banked hedges before draining. It is not an instant stop, enabled is.
