Summary by CodeRabbit

Improvements

• Ethereum receipts and ID-to-address resolutions are cached after reaching finalized chain state.
• Direct BLS, Secp256k1, and Delegated addresses are handled without unnecessary resolution.
• Ethereum state, storage, nonce, and fee-history queries provide more accurate finalized data.
• Improved diagnostics are provided when deterministic address or state resolution fails.
• API-version reporting and external block-producer support are available through Filecoin.SyncSubmitBlock.
• EVM traces correctly reflect self-destructed contracts.
• ChainNotify subscriptions close when clients fall behind.

Tests

• Expanded coverage for finality caching, degraded chains, fallback behavior, and multi-block chains.

Walkthrough

The change uses EC-calculated finality for address resolution and Ethereum receipt caching. Ethereum RPC state queries use actor-state helpers. Tests add multi-block tipset utilities and cover degraded-chain and cached-resolution behavior.

Changes

Finality and Ethereum state updates

Layer / File(s)	Summary
EC finalized epoch boundaries src/chain/store/chain_store.rs, src/rpc/methods/eth.rs	ID-address resolution and Ethereum receipt finalization use the EC calculator’s finalized epoch. Errors include resolution context.
Address resolution behavior src/message_pool/msgpool/msg_pool.rs, src/state_manager/address_resolution.rs, src/message_pool/msgpool/provider.rs	BLS, Secp256k1, and Delegated addresses bypass lookup. Tests verify heaviest-head setup, EC lookback boundaries, cache insertion, and error formatting.
Ethereum state and receipt queries src/rpc/methods/eth.rs	Code, storage, and nonce queries use actor-state helpers. Fee history reads receipts from the visited child tipset. Event collection receives an explicit optional argument.
Chain test support and release notes src/chain/store/index.rs, CHANGELOG.md, .config/forest.dic	Test utilities create validated multi-block child tipsets with unique block data. Changelog and dictionary entries are updated.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk:⚪ Minimal · up to 0d428

The PR moves ETH receipt and ID-to-address caching earlier based on EC finality; no actionable merge-blocking risk remains after normal checks and review.

Add regression coverage for every bypassed protocol.

The visible test at src/message_pool/msgpool/msg_pool.rs:748-762 covers only BLS addresses. Add Secp256k1 and Delegated cases, and verify that resolution does not populate the ID-to-address cache.
