All subgraph config files (networks.json, subgraph.yaml) and test
utils were referencing old pre-deterministic MetaBoard addresses.
Updated to the canonical address from LibMetaBoardDeploy and added
Solidity tests to enforce consistency across all references.

In `@CLAUDE.md`:
- Around line 1-4: Add the repository SPDX header to CLAUDE.md so it matches the
rest of the repo's license metadata: update the top of CLAUDE.md to include the
same SPDX-License-Identifier and copyright/REUSE header used elsewhere in the
project (ensure the exact SPDX identifier and copyright owner string used across
the repo are copied verbatim).
- Around line 27-51: The README section has markdownlint errors: add language
tags to the fenced code blocks (use "sh") and ensure blank lines surround each
fenced block and the section/subsection headings; specifically update the two
test command code fences to start with ```sh and have an empty line before and
after each fenced block, and insert blank lines above the "## Architecture"
heading and the "### Solidity (`src/`)", "### Rust (`crates/`)", and "###
Subgraph (`subgraph/`)" subsection headings so each heading is separated by a
blank line from surrounding text.

In `@foundry.toml`:
- Around line 12-21: The default profile enables ffi (ffi = true) which allows
any Solidity test to call vm.ffi() and execute host commands; remove or disable
the global ffi flag and instead make FFI opt-in by creating a separate profile
(e.g., [profile.ci] ffi = true) or require passing the CLI --ffi flag in CI;
update any test docs or CI job to run tests that need vm.ffi() under that
profile/flag and ensure tests like subgraph/tests/address.ts that call vm.ffi()
run only when FFI is explicitly enabled.

In `@test/lib/deploy/LibMetaBoardDeploy.t.sol`:
- Around line 59-77: Replace fragile vm.ffi-based assertions in
testSubgraphYamlAddress and testSubgraphTestAddressTs: stop shelling out with
vm.ffi (and dependency on yq/grep) and instead read the files with vm.readFile
and extract the address with a deterministic parser (e.g., vm.parseJsonAddress
for JSON fixtures or parse the YAML into JSON first) and compare to
LibMetaBoardDeploy.METABOARD_DEPLOYED_ADDRESS; if you must keep yq, change the
yq query to selector-based (e.g., select(.name == "metaboard0") |
.source.address) to avoid relying on .dataSources[0] ordering.

thedavidmeister and others added 3 commits March 12, 2026 17:52
Add deploy start block constants for all 5 supported networks to
LibMetaBoardDeploy. Add tests that verify start blocks via binary
search (findDeployBlock) and boundary check (isStartBlock) against
live RPCs. Add tests that parse networks.json to assert addresses
and startBlock values match the Solidity constants.

Remove unsupported networks (mainnet, berachain-mainnet, sonic) from
networks.json. Add flare and base-sepolia. Fix all startBlock values
to match the verified deploy blocks.

135-144: ⚠️ Potential issue | 🟡 Minor

grep -P is not portable; BSD grep (macOS default) lacks PCRE support.

This test will fail on macOS or other systems without GNU grep. The regex pattern is compatible with extended regex, so switching to -E makes this portable:

🔧 Suggested fix
 function testSubgraphTestAddressTs() external {
     string[] memory inputs = new string[](4);
     inputs[0] = "grep";
-    inputs[1] = "-oP";
+    inputs[1] = "-oE";
     inputs[2] = "0x[0-9a-fA-F]{40}";
     inputs[3] = "subgraph/tests/address.ts";

42-55: 🧹 Nitpick | 🔵 Trivial

Add blank lines after subsection headings.

The markdownlint-cli2 MD022 rule requires blank lines both above and below headings. Lines 42, 48, and 53 have blank lines above but are missing blank lines below before the list items begin.

📝 Proposed fix
 ### Solidity (`src/`)
+
 - `src/concrete/MetaBoard.sol` — Main contract; emits `MetaV1_2` events with sender, subject, and metadata bytes
 - `src/lib/LibMeta.sol` — Metadata validation; checks magic number prefix `0xff0a89c674ee7874`
 - `src/lib/LibDescribedByMeta.sol` — Helper for contracts implementing `IDescribedByMetaV1`
 - `src/lib/deploy/LibMetaBoardDeploy.sol` — Deterministic deployment using Zoltu deployer pattern
 
 ### Rust (`crates/`)
+
 - `crates/cli` — `rain-metadata` binary; metadata generation/validation for multiple types (authoring, dotrain, Solidity ABI, etc.)
 - `crates/bindings` — Solidity bindings generated via `alloy::sol!` from JSON ABIs in `/out`
 - `crates/metaboard` — GraphQL client (Cynic) for querying MetaBoard subgraph data
 
 ### Subgraph (`subgraph/`)
+
 - AssemblyScript handlers indexing `MetaV1_2` events from MetaBoard

@coderabbitai assess this PR size classification for the totality of the PR with the following criterias and report it in your comment:

S/M/L PR Classification Guidelines:

This guide helps classify merged pull requests by effort and complexity rather than just line count. The goal is to assess the difficulty and scope of changes after they have been completed.

Small (S)

Characteristics:

  • Simple bug fixes, typos, or minor refactoring
  • Single-purpose changes affecting 1-2 files
  • Documentation updates
  • Configuration tweaks
  • Changes that require minimal context to review

Review Effort: Would have taken 5-10 minutes

Examples:

  • Fix typo in variable name
  • Update README with new instructions
  • Adjust configuration values
  • Simple one-line bug fixes
  • Import statement cleanup

Medium (M)

Characteristics:

  • Feature additions or enhancements
  • Refactoring that touches multiple files but maintains existing behavior
  • Breaking changes with backward compatibility
  • Changes requiring some domain knowledge to review

Review Effort: Would have taken 15-30 minutes

Examples:

  • Add new feature or component
  • Refactor common utility functions
  • Update dependencies with minor breaking changes
  • Add new component with tests
  • Performance optimizations
  • More complex bug fixes

Large (L)

Characteristics:

  • Major feature implementations
  • Breaking changes or API redesigns
  • Complex refactoring across multiple modules
  • New architectural patterns or significant design changes
  • Changes requiring deep context and multiple review rounds

Review Effort: Would have taken 45+ minutes

Examples:

  • Complete new feature with frontend/backend changes
  • Protocol upgrades or breaking changes
  • Major architectural refactoring
  • Framework or technology upgrades

Additional Factors to Consider

When deciding between sizes, also consider:

  • Test coverage impact: More comprehensive test changes lean toward larger classification
  • Risk level: Changes to critical systems bump up a size category
  • Team familiarity: Novel patterns or technologies increase complexity

Notes:

  • the assessment must be for the totality of the PR, that means comparing the base branch to the last commit of the PR
  • the assessment output must be exactly one of: S, M or L (single-line comment) in format of: SIZE={S/M/L}
  • do not include any additional text, only the size classification
  • your assessment comment must not include tips or additional sections
  • do NOT tag me or anyone else on your comment
