Summary

Testnet blocks 69038325–69071492 (33,168 blocks) are missing from the hl-testnet-evm-blocks S3 bucket, so nodes syncing from S3 stall at 69038324. This embeds them next to the existing 50927214–50929512 gap (#129). BlockStore serves them the same way, so syncing works on any block source.

• src/pseudo_peer/testnet_gaps_69038325.json.lz4: lz4-compressed JSON Vec<BlockAndReceipts>, the same format as testnet_gaps.json.lz4 (5.6 MB).
• patch.rs: loads both embedded files (testnet only, as before).
• Test embedded_testnet_gaps_chain: checks the range is complete, chains by parent hash, and links to the S3 blocks on both sides.

How the blocks were rebuilt

From another nanoreth node's RPC: eth_getBlockByNumber(full), eth_getBlockReceipts and eth_blockPrecompileData. That node runs in default mode, so system txs are listed. Each block is converted to its DB form and then to BlockAndReceipts::from_db, the same thing hl_syncGetBlock serves.

Checks per block:

• Hashes: the header re-hashes to the RPC block hash, and every tx (system txs included) re-hashes to its RPC tx hash.
• Receipts: regular-tx receipts reproduce the header's receipts root, logs bloom and gas used.
• Chain: the parent-hash chain is pinned to S3 on both sides. It starts at the hash of 69038324 (0x718af9…9b25) and ends at the parent hash of 69071493 (0x3051f8…1f8b).
• Precompile data: all 23 gap blocks that call read precompiles (found by tracing every block with txs) carry their recorded results.
• Converter check: the same conversion run on 999 post-gap blocks that do exist in S3 reproduces them exactly.

Verification

• Sync: synced a testnet archive from 68144874 through the gap to the head. Every embedded block was re-executed and passed post-execution validation.
• Against QuickNode: balances, nonces and code of 150 random gap-touched accounts, at 69038324, 69055000 and 69071492, match the source node (0 mismatches).
• Full state against hl-node: compared at 69237903 with a node initialized from hl-node state at 69224874 (via evm-init), covering every account, code and storage slot. The only differences are 79 empty accounts and 2 slots that already differ before the gap (unrelated, tracked separately), so none come from the gap blocks.
