Walkthrough

Adds the eth-skip-sender devnet command. It deploys contract fixtures and validates eth_call, eth_estimateGas, transaction submission, sender handling, revert data, state isolation, historical calls, and cross-contract callbacks.

Changes

Skip-sender devnet coverage

Layer / File(s) Summary
Command registration and test wiring
.github/workflows/forest.yml, mise.toml, scripts/devnet/README.md, scripts/devnet/test_harness.sh, src/dev/subcommands/devnet_cmd.rs
Registers eth-skip-sender and adds it to local workflows, tasks, harness documentation, and integration-test instructions.
Contract fixtures and bytecode generation
src/dev/subcommands/devnet_cmd/contracts/...
Adds Solidity fixtures and compiled bytecode for callback, error, and balance-transfer scenarios. The compiler script skips empty bytecode lines.
Deployment and RPC execution harness
src/dev/subcommands/devnet_cmd/eth_skip_sender.rs, src/dev/subcommands/tests_cmd/helpers.rs
Adds wallet and deployment setup, Forest and Lotus actor polling, funding, transaction submission, RPC wrappers, and retry handling.
Skip-sender behavior validation
src/dev/subcommands/devnet_cmd/eth_skip_sender.rs
Tests sender variants, CREATE, gas estimates, revert responses, transaction flows, parity, state isolation, historical calls, and cross-contract callbacks.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: ⚪ Minimal · up to d322c

This change adds devnet test coverage, and no actionable merge-blocking risk remains after normal checks and review.

Add a doc comment to the now-public poll.

poll is now part of the module's public surface and is called from eth_skip_sender.rs. Document the retry contract, so callers know that Ok(None) means "retry" and that the helper fails after POLL_TIMEOUT.

📝 Proposed doc comment
+/// Call `try_check` every [`POLL_WAIT_TIME`] until it returns `Ok(Some(value))`.
+///
+/// `Ok(None)` means "not ready yet"; the helper retries. An `Err` propagates
+/// immediately. If [`POLL_TIMEOUT`] elapses without a value, the helper fails.
+/// `label` identifies the wait in the progress output and in the timeout error.
 pub async fn poll<F, Fut, T>(label: &str, mut try_check: F) -> anyhow::Result<T>
 where
     F: FnMut() -> Fut,
     Fut: Future<Output = anyhow::Result<Option<T>>>,
 {

We already have similar contracts src/tool/subcommands/api_cmd/contracts.

Not sure if they are needed or maybe you can move them to common place. Just a suggestion because it's not really a big contract but still.
