fix: create alias oracle once per block instead of per address#103
Conversation
Move AliasOracleFactory::create() out of the per-address should_alias helper and into run_evm, so all addresses in a block share the same host state snapshot. Expand the comment in create() with a full correctness analysis of why Latest is safe. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Summary
Performance fix: creates the alias oracle once per block instead of once per address lookup.
AliasOracleFactory::create()out of the per-addressshould_aliashelper and intorun_evm, so all addresses in a block share the same host state snapshotshould_aliashelper methodAliasOracleFactory::create()with a full correctness analysis of whyLatestis safe (EOA→contract transitions require a birthday attack, and even then the failure mode is benign over-aliasing)Previously, each address in a block called
create()→state_by_block_number_or_tag(Latest), opening a new state snapshot per address. Now a single snapshot is shared across the block.Equivalent to #102 (targeting
