Wire the EVM side of the always-on DEX settlement money path 0x9999. It is ACTIVE
on every chain from genesis with NO config entry — neither a genesis-inlined
precompile nor a precompileUpgrades timestamp. Zero per-net config, one way.
Activation is DISPATCH-only (genesis state is consensus-critical and immutable):
- params.GetExtrasRules injects every modules.AlwaysOnModules() entry into the
enabled precompile set unconditionally (every chain, every timestamp). This is
what PrecompileOverride.IsPrecompileEnabled consults, so 0x9999 runs for a
tx-to-0x9999, a low-level CALL/STATICCALL, and the 0x9010 V4 forward.
- ApplyPrecompileActivations writes NO genesis state for always-on modules. An
EXTCODESIZE marker at genesis would change the genesis hash and FORK existing
networks (a fresh-syncing node would disagree with the committed genesis). The
real lux-mainnet genesis hash is preserved (TestSkipPostMergeFieldsGenesisHash).
- The always-on module's Configurator is never invoked (no activating config).
DChainID runtime resolution (THE crux): contract.AtomicState gains DChainID(); the
EVM adapter (accessibleStateAdapter) resolves it from the consensus context via
runtime.GetBCLookup().Lookup("D") — the dexvm "D"/"dex"/"dexvm" alias the node
registers in initChainAliases before any chain bootstraps. Identical on every
validator and re-execution; ids.Empty on a network with no dexvm (seam stays closed,
fail-secure). The registry bridge forwards DChainID across the internal/external
AtomicState surfaces. modules.Module gains AlwaysOn (+ AlwaysOnModules()), bridged
from github.com/luxfi/precompile.
deps: precompile v0.5.51 -> v0.5.52 (DChainID + AlwaysOn + always-on settle module).
Tests: core suite green incl. the real-mainnet genesis-hash guards. New
core/precompile_alwayson_test.go: 0x9999 registers AlwaysOn, is dispatch-enabled with
NO config at genesis + far-future ts, and writes NO genesis state (genesis-hash
immutability). (Two pre-existing unrelated failures: params/config_test.go references
a removed DurangoTimestamp field; mainnet upgrade.json aiMining/warp timestamp guards
— both fail identically on pristine main.)
