dexvm (D-Chain / DEX) is ALREADY 1ms-capable: nanosecond wire timestamps (UnixNano round-trip on
both linear Block and DAG DexVertex paths), Config.BlockInterval default already 1ms ('1ms blocks
for HFT'), deriveBlockHash on UnixNano, no whole-second truncation anywhere. The one artifact was a
dead ChainVM.blockInterval field (100ms, never read repo-wide) that falsely implied a floor — removed
(zero readers → semantically inert). Config.BlockInterval is now the single source of truth. Added two
//go:build redteam tests locking the previously-untested monotonicity clamp at ns resolution across
BOTH proposer entrypoints (BuildVertex + BuildBlock): a 1ms clock advance survives byte-exactly, the
sub-second component is preserved, a backward clock is clamped non-decreasing. Fairness invariants
unchanged (height is the strict total-order sequencer; block time non-decreasing; distinct sub-second
times → distinct block hashes; proposer-carried time, no wall-clock ordering race). Settlement/matching
untouched. Combined with the sub-second proposervm (node v1.36.19 UnixMilli window), a co-located
fiber/InfiniBand DEX runs 1ms blocks natively.
