Important

Review skipped

Review was skipped due to path filters

⛔ Files ignored due to path filters (1)

• src/generated/CodeGennable.pointers.sol is excluded by !**/generated/**

CodeRabbit blocks several paths by default. You can override this behavior by explicitly including those paths in the path filters. For example, including **/dist/** will override the default block on the dist directory, by removing the pattern from both the lists.

You can disable this status message by setting the reviews.review_status to false in the CodeRabbit configuration file.

Walkthrough

The EVM version in foundry configuration was upgraded from Paris to Cancun. Additionally, the rain.math.binary submodule dependency was updated to a newer commit version.

Pre-merge checks and finishing touches

❌ Failed checks (1 inconclusive)

Check name	Status	Explanation	Resolution
Title check	❓ Inconclusive	The title 'update binary' is vague and generic, using non-descriptive language that doesn't clearly convey the specific change made in the pull request.	Consider using a more descriptive title that specifies the exact update, such as 'Update rain.math.binary submodule and set evm_version to cancun' to better communicate the changes.

foundry.toml (1)

24-24: Clarify the motivation for the EVM version configuration update.

The evm_version is explicitly set to "cancun", which aligns with Solidity 0.8.25's default and recommended EVM target. However, the PR description is empty, offering no context for this change.

Since Solidity 0.8.25 defaults to Cancun and uses Cancun-specific codegen optimizations (MCOPY), this configuration is appropriate and carries no compatibility risk. The rain.math.binary submodule will inherit this configuration and is compatible.

For clarity, please explain in the PR description:

• Why this configuration change is being made now
• Whether this targets a specific deployment or is a general maintenance update

lib/rain.math.binary (1)

1-1: The new submodule commit f44f846a… is valid and accessible. The commit exists in the remote rain.math.binary repository and is currently the HEAD of the main branch. However, visibility into the changelog, compatibility with the current codebase, security vulnerabilities, and EVM version alignment (Cancun) still requires examination of the rain.math.binary repository directly or documentation of the changes between the old commit (54450d6…) and the new one.

⚠️ Potential issue | 🔴 Critical

⚠️ Missing PR documentation blocks review.

This PR lacks a Motivation section explaining why the binary was updated, and a Solution section describing what changed. Dependency updates—especially submodules—require clear documentation to assess impact and risk.

Additionally, the checklist items in the PR template remain unchecked, which signals incomplete review preparation.

Before proceeding, please:

1. Fill in the Motivation section explaining why this submodule update is needed
2. Summarize the key changes in the rain.math.binary commits (old vs. new)
3. Explain the relationship between the EVM version change (Paris → Cancun) and this update
4. Check the PR template confirmation items

blocks: add a Motivation section explaining why the rain.math.binary
submodule/binary was updated, a Solution section summarizing key commits and the
exact changes (old vs new), a brief explanation of how the EVM version change
from Paris to Cancun relates to and impacts this update, and mark all PR
template checklist items as completed; update the PR description to include
these sections and checklist confirmations so reviewers can assess impact and
