fix(drive): ignore time based update fields in proof verification of data contract updates

[QuantumExplorer]

Issue being fixed or feature implemented

Fixes the verification of data contract updates by ignoring time based fields that are auto updated during execution.

What was done?

• Added checks for keywords and description in the equality comparison of DataContractInSerializationFormat.
• Updated the test for data contract updates to include proof generation and verification.
• Adjusted the verification logic in the Drive implementation to utilize a more accurate comparison method.

How Has This Been Tested?

• Unit tests were added to verify that the data contract update can add new tokens and that the state transition proof is correctly verified.

Summary by CodeRabbit

• Bug Fixes

  • Improved equality checks for data contracts to include the "keywords" and "description" fields, ensuring more accurate comparisons.
  • Verification logic for data contract updates now ignores automatically managed fields, reducing false mismatches during proof validation.

• Tests

  • Enhanced tests for data contract updates by adding cryptographic proof generation and verification steps, increasing test coverage and reliability.

Walkthrough

The changes update the equality comparison logic for data contracts to include the keywords and description fields. Related test and verification logic now use this revised comparison method, ensuring that state transition proofs and their verification consider these fields. No public API signatures or control flow were otherwise altered.

Changes

File(s)	Summary
packages/rs-dpp/src/data_contract/serialized_version/mod.rs	Updated eq_without_auto_fields to compare keywords and description fields in addition to existing ones.
packages/rs-drive-abci/src/execution/validation/state_transition/state_transitions/...	Enhanced test to generate and verify proof after a data contract update, using the revised equality check.
packages/rs-drive/src/verify/state_transition/verify_state_transition_was_executed...	Changed contract comparison to use eq_without_auto_fields for proof verification, ignoring auto fields.

• fix: data contract proof doesn't work with new auto fields #2501: Extends the eq_without_auto_fields method, directly related as this PR builds on and modifies that method.
• fix(drive): verification of token purchase can not verify the purchase cost as this can be lower than the agreed price #2617: Both PRs involve equality checks in state transition verification, though for different fields and contexts.

Poem

In fields of code where contracts dwell,
Two new friends join the tale to tell—
Keywords and descriptions, now in sight,
Compared with care, to get things right.
Proofs are checked, transitions true,
A bunny hops—this code’s for you!

packages/rs-dpp/src/data_contract/serialized_version/mod.rs (1)

133-134: LGTM! Essential fields properly added to equality comparison.

The addition of keywords and description fields to the equality comparison ensures comprehensive contract validation while maintaining the method's purpose of excluding only auto-generated fields. This enhances the accuracy of data contract verification during state transitions.

packages/rs-drive/src/verify/state_transition/verify_state_transition_was_executed_with_proof/v0/mod.rs (1)

106-108: LGTM! Verification logic correctly updated to use enhanced equality comparison.

The change to use eq_without_auto_fields instead of direct equality is consistent with the enhanced method implementation and ensures accurate verification of data contract updates. This properly excludes auto-generated fields while validating all relevant contract attributes including the newly added keywords and description fields.

packages/rs-drive-abci/src/execution/validation/state_transition/state_transitions/data_contract_update/mod.rs (3)

1230-1231: LGTM: Appropriate imports for proof verification functionality.

The new imports for StateTransitionProofResult and Drive are correctly added to support the enhanced test functionality for proof generation and verification.

---

1293-1293: Good change: Clone needed for later proof verification.

The clone of updated_data_contract is necessary because the contract object is consumed during the state transition creation and will be needed later for the proof verification step.

---

1334-1353: Excellent enhancement: Comprehensive proof verification testing.

This addition significantly strengthens the test by verifying the complete proof generation and validation pipeline for data contract updates. The implementation correctly:

• Generates a cryptographic proof of the state transition execution
• Verifies the proof using the appropriate verification method
• Includes proper error handling with detailed error messages
• Asserts the expected verification result type

This aligns perfectly with the PR objective of ensuring correct verification process for data contract updates.
