Walkthrough

This PR updates documentation files to reflect API changes in the TypeScript client library. It fixes a Markdown code fence syntax issue in CLAUDE.md and updates client-guide.md to demonstrate new factory method patterns for creating TestRpc and SystemAccountMetaConfig instances.

Changes

Cohort / File(s)	Summary
Documentation syntax fix zk-compression-docs/CLAUDE.md	Corrects closing Markdown code fence in References section and removes trailing "No newline at end of file" indicator
API usage pattern updates zk-compression-docs/compressed-pdas/client-library/client-guide.md	Updates TestRpc instantiation from getTestRpc(lightWasm) to TestRpc.create(lightWasm) and SystemAccountMetaConfig initialization from direct constructor to SystemAccountMetaConfig.new(programId) factory method

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~10 minutes

• Verify that TestRpc.create() and SystemAccountMetaConfig.new() accurately reflect the current public API signatures in the implementation
• Confirm the documentation examples will work correctly with the updated factory method patterns

275-288: Markdown code fence formatting now properly closed.

The explicit closing fence on line 288 correctly resolves the markdown syntax. The reference section tree structure is well-organized with consistent indentation and formatting. The mapping is comprehensive and links are properly formatted.

To ensure all GitHub URLs remain current and accessible, please verify a sampling of URLs from each section point to valid repository paths. For example:

• Verify https://github.com/Lightprotocol/light-protocol/tree/main/js/compressed-token exists
• Verify https://github.com/Lightprotocol/program-examples/tree/main/basic-operations exists

If any URLs have changed due to branch renames or repository restructuring, they should be updated throughout this mapping file.

119-122: Verify TypeScript SDK factory method for TestRpc.

The code snippet changes from getTestRpc(lightWasm) to TestRpc.create(lightWasm), reflecting a factory method pattern. This is a significant API surface change that needs confirmation against the current @lightprotocol/stateless.js implementation.

Please verify that the TestRpc.create(lightWasm) method exists and is the correct API in the latest version of @lightprotocol/stateless.js. You can check the SDK documentation at https://lightprotocol.github.io/light-protocol/stateless.js/index.html or the source code to confirm the method signature and availability.

722-729: Verify SystemAccountMetaConfig static constructor API.

The code snippet changes from direct constructor SystemAccountMetaConfig(programId) to a static method SystemAccountMetaConfig.new(programId). This reflects a factory pattern, but requires verification against the current TypeScript client library implementation.

Please verify that SystemAccountMetaConfig.new(programId) is the correct API in the latest version of @lightprotocol/stateless.js or @lightprotocol/compressed-token. Check the SDK documentation or source code to confirm this static method exists and accepts programId as its parameter.

⚠️ Potential issue | 🟡 Minor

Add blank line before code fence (MD031).

Markdown linting indicates that code fences should be surrounded by blank lines. A blank line is needed before line 720 ({% code overflow="wrap" %}).

Apply this diff to fix the formatting:

 2. Call `addSystemAccounts(systemAccountConfig)` - the SDK populates `systemAccounts` with Light System accounts, including the CPI signer PDA derived from your program ID

+
 {% code overflow="wrap" %}
 ```typescript
 const systemAccountConfig = SystemAccountMetaConfig.new(programId);

In zk-compression-docs/compressed-pdas/client-library/client-guide.md around
lines 720 to 726, the code fence starting with `{% code overflow="wrap" %}`
needs a blank line above it to satisfy MD031; insert a single blank line
immediately before the `{% code overflow="wrap" %}` line so the fenced code
block is separated from the preceding paragraph/content.
