✅ Clean
- Reviewed the three new/updated pages:
docs/dev/read/overview.md,docs/dev/read/rpc/error-codes.md, anddocs/dev/send-tx/gas-estimation.md. - Frontmatter, sentence-per-line prose, relative
.mdcross-links, and the#request-body-limitsanchor all conform to the layer conventions indocs/AGENTS.mdanddocs/dev/AGENTS.md. - The 1.5 MiB / 128 KiB values appear in both
overview.mdandgas-estimation.md, but that is consistent with the layer style rule on self-contained pages and the gas-estimation page links back to the canonical table — not flagged as duplication. - No new actionable findings. Still open from earlier reviews: none.

Summary
The public MegaETH RPC endpoint enforces request body size limits that vary by method class, but this behavior was not documented. Developers deploying large contracts could hit an undocumented
413/-32099(payload too large) rejection when estimating gas or simulating calls with full-size initcode.This adds documentation for the three body-size tiers and the associated error:
docs/dev/read/overview.md— new Request Body Limits section: 2.5 MiB for transaction submission, 1.5 MiB for large reads/simulations (eth_call,eth_callMany,eth_createAccessList,eth_estimateGas), and 128 KiB for all other methods.docs/dev/read/rpc/error-codes.md— new413/-32099(payload too large) row.docs/dev/send-tx/gas-estimation.md— note that gas estimation for large deployments sends full initcode and is allowed up to the 1.5 MiB large-read limit.Test plan
