Closes CR-2 from the cross-stack adversarial audit: PQ posture on
multi-chain hosts moves from a process-global to a per-chain
ChainConfig setting. A strict-PQ subnet and a permissive L1 in the
same node process now refuse / admit classical primitives correctly,
independent of which subnet last initialised.
Surface:
- NetworkUpgrades.StrictPQTimestamp *uint64 (json:"strictPQTimestamp")
nil = chain is classical-permissive (default for non-Lux integrators)
0 = strict-PQ from genesis (set by plugin/evm when config.PQ=true)
- NetworkUpgrades.IsStrictPQ(time uint64) bool — fork rule
- chainConfigAdapter.IsStrictPQ — bridges params/extras into the
contract.StrictPQReporter contract that stateful precompiles call.
- extChainConfigBridge.IsStrictPQ — type-asserts via a local
interface so non-Lux chains integrating Lux precompiles remain
classical-permissive (no contract widening forced on them).
- plugin/evm: when config.PQ=true, vm.chainConfig.PQ is installed
(covers 0x01..0x0a standard precompiles via runPrecompile gate) AND
extras.StrictPQTimestamp is set to genesis (covers Lux stateful
precompiles — KZG, Groth16, PLONK, fflonk, Halo2, BN254-Pedersen,
BabyJubJub, Pallas/Vesta — via contract.RefuseUnderStrictPQ).
Module bumps:
- github.com/luxfi/geth v1.16.91
(bundles MLDSATxType (0x42) + per-chain PQ profile gate)
- github.com/luxfi/pq v1.0.1-0.20260512064747-3d4c9414e15e
(RefuseUnder promoted to method on *Profile)
No semantic change for chains that do not opt into PQ:
StrictPQTimestamp is nil, IsStrictPQ returns false, every classical
primitive admits, gas accounting unchanged.
