[Standard] 0g - Mainnet - Upgrade to v1.0.7

Scheduled for Oct 1, 00:00 UTC - Oct 2, 00:00 UTC

Scheduled

We are upgrading our 0g Mainnet infrastructure to Aristotle v1.0.7 on 2026-10-01. This is an RPC-only release that fixes a critical correctness bug in eth_estimateGas and removes a CPU-amplification vector in the gas estimator. No consensus or state-transition changes are included. Brief interruptions to RPC availability may occur on that date.

RPC Changes:
- eth_estimateGas — Fixed critical bug where gas estimates were being seeded from post-settlement gas (raising gas_used to 80% of the cap), causing the method to return cap-sized limits instead of actual usage. This resulted in gas estimates up to ~850× too large. Estimates are now seeded from pre-settlement gas, matching 0g-geth behavior. Additionally, EIP-7623 calldata floor computation has been optimized to run once per transaction instead of per frame, eliminating a CPU-amplification vector.
