Walkthrough

This PR fixes multiple Filecoin RPC method compatibility issues with Lotus Gateway by updating test configurations, filter lists, and RPC handling. Methods previously marked as broken are now validated as fixed, and test infrastructure is updated to support proper validation.

Changes

Cohort / File(s)	Summary
Gateway Test Configuration scripts/tests/api_compare/docker-compose.yml, scripts/tests/api_compare/filter-list-gateway	Updated docker-compose service with --api-wait-lookback-limit 2000 flag; moved 7 RPC methods from "broken" to fixed status; added EthGetBlockReceiptsLimited to "not supported" list.
RPC Method Enhancements src/rpc/methods/eth.rs, src/rpc/log_layer.rs	Added serde(default) attribute to BlockHash struct's require_canonical field; refactored log_layer.rs to use centralized log_enabled() helper instead of duplicated tracing::enabled! checks.
Documentation CHANGELOG.md	Added Fixed entry documenting Filecoin.EthGetBalance compatibility issue resolution (issue #6577).

🚥 Pre-merge checks | ✅ 1 | ❌ 4

❌ Failed checks (3 warnings, 1 inconclusive)

Check name	Status	Explanation	Resolution
Title check	⚠️ Warning	The PR title focuses on the test infrastructure change (adding a flag to docker-compose), but the changeset includes broader code fixes affecting RPC methods beyond just the test setup.	Revise title to reflect the full scope, such as 'fix(rpc): fix Filecoin RPC methods compatibility with lotus-gateway' to accurately represent all fixes included.
Out of Scope Changes check	⚠️ Warning	Changes to src/rpc/log_layer.rs (tracing refactor) and src/rpc/methods/eth.rs (serde attribute) appear tangentially related to RPC fixes but lack clear connection to lotus-gateway compatibility.	Clarify the necessity of log_layer.rs and eth.rs changes for lotus-gateway compatibility; consider separating unrelated refactoring into a distinct PR if not essential.
Docstring Coverage	⚠️ Warning	Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%.	Write docstrings for the functions missing them to satisfy the coverage threshold.
Linked Issues check	❓ Inconclusive	The PR removes 6 methods from the 'broken' filter list, directly addressing issues #6581-6584, #6578, #6579, #6577, though full functional fixes are unclear from code changes alone.	Verify that code changes in eth.rs and log_layer.rs substantively fix the broken RPC methods; provide additional documentation linking specific code changes to each resolved issue.
