Two coupled knobs for differentiated cadence — co-located D-Chain/DEX (fast) vs public C-Chain (standard): 1. MinBlkDelay was hardcoded to the 1s DefaultMinBlockDelay in chains/manager.go, ignoring its own --proposervm-min-block-delay flag. Now wired node.Config → ManagerConfig → proposervm.Config (0 ⇒ 1s default). High-throughput nets set it low. 2. Block timestamps were Truncate(time.Second) at 4 sites, quantizing cadence to 1s regardless of WindowDuration — so a sub-second window inflated slot numbers without finer time resolution and could NOT produce blocks faster than 1/s. Truncation now tracks proposer.TimestampGranularity() = min(1s, WindowDuration): mainnet (>=1s) keeps exact 1-second block times; sub-second windows get matching sub-second timestamps. Measured: 1s window/delay → ~95-104 TPS, byte-identical 5/5 finality (unchanged from before, no regression). NOTE: true sub-second cadence additionally requires a slot-handoff fix — at 100ms the slot recomputed in buildChild from a drifted 'now' can differ from the slot timeToBuild scheduled, causing errUnexpectedProposer verify drops; that + multi-sender saturation is the next step. These knobs are the necessary foundation. Co-authored-by: Hanzo Dev <dev@hanzo.ai>
