The AlwaysOn DEX settlement precompile (0x9999) had its EXTCODESIZE marker baked into EVERY chain's genesis state unconditionally (parent==nil in ApplyPrecompileActivations), mutating the genesis state root. This changed the genesis hash of every chain genesised before the DEX activation, breaking RLP re-import of the real archived Lux mainnet (0x3f4fa2a0), Lux testnet (0x1c5fe377) and Zoo mainnet (0x7c548af4) — all re-genesised Nov 2024, before the Dec-2025 activation. Fix: an AlwaysOn system precompile carries a protocol ActivationTime (Dec 2025 for 0x9999, set by the registry bridge — a fork-like constant, not per-net config). Its genesis marker is installed ONLY IF ActivationTime <= the genesis timestamp; otherwise it activates later, on the block transition that crosses ActivationTime during history replay. Dispatch (GetExtrasRules) is gated on the same timestamp so a codeless address never dispatches. A chain born before activation reproduces its ORIGINAL genesis byte-for-byte; a fresh chain born at/after activation still gets 0x9999 at genesis. Verified against the real RLP block-0 of all three chains (byte-identical reproduction) plus a fresh post-activation chain. Corrects two pre-existing tests that had hardcoded the buggy with-0x9999 hashes as "canonical". Co-authored-by: Hanzo Dev <[email protected]>
