Checks

By submitting this for review, I'm confirming I've done the following:

• made this PR as small as possible
• unit-tested any new functionality
• linked any relevant issues or PRs
• included screenshots (if this involves a front-end change)

Summary by CodeRabbit

• Documentation

  • Added info on the Zoltu deterministic deployment proxy with a link, highlighting cross-network data accessibility.

• Tests

  • Updated performance snapshots for multiple DataContract test cases to reflect current metrics.

• Chores

  • Updated internal dependencies/submodules and made minor import adjustments; no functional impact.

No user-facing behavior changes or API updates.

Walkthrough

Updates refresh numeric gas/performance snapshots, add README text linking a deterministic deployment proxy, bump two submodule pointers, add a new unused import with a lint suppression in LibDataContract.sol, and add foundry.lock to REUSE.toml paths. No public APIs or runtime logic changed.

Changes

Cohort / File(s)	Summary of Changes
Performance snapshots .gas-snapshot	Updated numeric gas/performance metrics for nine DataContractTest cases; test IDs unchanged.
Documentation README.md	Added paragraph referencing Zoltu deterministic deployment proxy and included link.
Submodules lib/forge-std, lib/rain.solmem	Updated submodule commit references (pointer bumps); no code or API changes.
Internal import / lint src/lib/LibDataContract.sol	Added import of LibPointer/Pointer from .../lib/LibPointer.sol and a forge-lint suppression for the unused import; no behavior/API changes.
REUSE metadata REUSE.toml	Added foundry.lock to the annotated paths list.

Check name	Status	Explanation	Resolution
Title Check	⚠️ Warning	The title “2025 09 25 audit” is vague and only indicates a date without summarizing the main changes such as updated gas snapshots, README additions, and submodule updates, so it fails to inform reviewers about the PR’s intent.	Please rename the PR to a concise phrase that reflects the key modifications, for example “Update gas performance snapshots and add Zoltu deterministic proxy docs.”

15-17: Additional path licensing looks correct

Extending this annotation to cover both the REUSE config itself and foundry.lock keeps the licensing metadata consistent with the rest of the repo footprint. No issues spotted.

README.md (1)

18-22: LGTM!

Good call-out on the deterministic deployment proxy; the context is useful for integrators.

lib/rain.solmem (1)

1-1: Submodule bump looks fine.

Pointer update only; no additional action required.

.gas-snapshot (1)

1-9: Gas numbers refreshed as expected.

The updated metrics align with the latest run; no issues from my side.

lib/forge-std (1)

1-1: Submodule pointer bump acknowledged.

The pointer update aligns with the stated dependency refresh, and I see no issues with this change.

🛠️ Refactor suggestion | 🟠 Major

Keep the lint clean by importing only what’s used.

LibPointer isn’t referenced anywhere in this file, so we shouldn’t suppress the lint warning just to keep the build green. Drop the directive and import only Pointer.

-// forge-lint: disable-next-line(unused-import)
-import {LibPointer, Pointer} from "../../lib/rain.solmem/src/lib/LibPointer.sol";
+import {Pointer} from "../../lib/rain.solmem/src/lib/LibPointer.sol";

📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Suggested change

	// forge-lint: disable-next-line(unused-import)
	import {LibPointer, Pointer} from "../../lib/rain.solmem/src/lib/LibPointer.sol";
	import {Pointer} from "../../lib/rain.solmem/src/lib/LibPointer.sol";

🤖 Prompt for AI Agents

In src/lib/LibDataContract.sol around lines 5 to 6, the file imports both
LibPointer and Pointer and disables the unused-import lint rule; remove the
lint-disable directive and update the import to only import Pointer from
"../../lib/rain.solmem/src/lib/LibPointer.sol" (drop LibPointer from the import
list) so the file imports exactly what it uses and the lint stays clean.
