Walkthrough

This PR adds documentation to the pallas-configs README with usage examples, extends the Pool struct in shelley.rs with two new optional fields (owners and registration_deposit) using serde defaults, and introduces comprehensive partner genesis test data in JSON format.

Changes

Cohort / File(s)	Summary
Documentation pallas-configs/README.md	Added descriptive text and Rust code example demonstrating how to load Shelley genesis config and access staking pools with their pledge information.
Core Data Structures pallas-configs/src/shelley.rs	Added Pool.owners field (Vec) and Pool.registration_deposit field (Option), both with serde(default) to handle missing fields during deserialization. Added comprehensive test suite for partner genesis staking parsing, validating pool attributes and stake mappings.
Test Data test_data/partner-shelley-genesis.json	Introduced complete test genesis configuration in JSON format covering network parameters, protocol settings, staking pools, relay configurations, and fund allocations.

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~20 minutes

• Review serde(default) attribute application and deserialization behavior for both new Pool fields
• Validate the new test suite logic, particularly pool field assertions and stake mapping verification
• Verify partner genesis test data structure aligns with expected schema and covers realistic configurations

Poem

🐰 A pool of new fields now takes shape,
With owners and deposits to escape,
The genesis data, shiny and new,
Tests hopping through—it all rings true!
Configuration's ready, let's stake with care,
Pallas configs blooming everywhere! 🌱

❌ Failed checks (1 warning)

Check name	Status	Explanation	Resolution
Title check	⚠️ Warning	The title mentions 'ensure shelley devnet config parses correctly' but the PR objectives indicate the main change is removing unnecessary serde aliases from the staking pool config because partner genesis now uses canonical keys.	Update the title to accurately reflect the primary change: 'fix(configs): remove unnecessary serde aliases from staking pool config' to better match the stated objectives and actual modifications.

274-319: Test coverage missing for the new registration_deposit field.

The test thoroughly validates most Pool fields including the defaulted owners field, but doesn't verify that registration_deposit correctly defaults to None when absent from the JSON.

Add an assertion after line 308 to verify the new field:

     );
     assert_eq!(pool.margin.numerator, 0);
+    assert_eq!(pool.registration_deposit, None);
 
     let stake = staking

test_data/partner-shelley-genesis.json (1)

67-67: Static analysis false positive: These are legitimate test data.

The static analysis tool flagged the keyHash values as potential API keys. These are actually Cardano credential key hashes (public identifiers) within the staking pool reward account structures, which is the expected format for Shelley genesis configurations. Since this is test data for a Testnet environment, there's no security concern.

pallas-configs/README.md (1)

3-19: LGTM!

The documentation clearly explains the crate's purpose and provides a practical example demonstrating how to load and access staking pool data from Shelley genesis files.

pallas-configs/src/shelley.rs (1)

167-168: LGTM! Default handling correctly implemented.

The #[serde(default)] attributes are properly applied:

• owners: Vec<String> will default to an empty vector if omitted
• registration_deposit: Option<u64> will default to None if omitted

This allows the deserializer to handle partner genesis files that may not include these fields, maintaining backward compatibility.

Also applies to: 174-175

⚠️ Potential issue | 🟡 Minor

The PR description doesn't match the actual changes.

The PR title states "Remove unnecessary serde aliases" and the description says "Removes unused serde alias attributes," but the actual changes show:

1. Adding #[serde(default)] to the existing owners field (line 167)
2. Adding a new registration_deposit field with #[serde(default)] (lines 174-175)

These are additions, not removals. Additionally, #[serde(default)] is not a serde "alias" attribute—it provides default values for missing fields during deserialization. Please update the PR title and description to accurately reflect that this PR adds default handling for optional Pool fields to support partner genesis configurations.
