Establish Contract-Backend Consistency Test Harness

[grantfox-oss]

Description:

Create integration tests that compare backend-indexed state with on-chain contract query results.

Tasks:

• Add fixture-driven tests for proposal, vote, stream, and burn event ingestion
• Add consistency checker asserting indexed aggregates match on-chain state
• Include delayed-indexing scenarios and recovery/replay tests

Acceptance Criteria:

Backend and contract state remain consistent across ingestion and replay paths.

Gm maintainer,

I’d like to work on this issue.

I have experience working with blockchain indexers, integration testing, and event-driven backend systems. I will add fixture-driven integration tests for proposal, vote, stream, and burn event ingestion, and implement a consistency checker that verifies backend-indexed aggregates match the contract’s on-chain query results.

I will also include delayed-indexing scenarios and replay/recovery tests to ensure the indexer remains consistent across ingestion and reprocessing paths.

ETA: 3–4 hours.

Please assign this issue to me.

I will build the consistency checker to diff indexed aggregates against on-chain query results after every fixture so delayed indexing and replay scenarios surface any drift before it reaches production.

I will also make sure recovery paths are tested and passing before the PR is opened.

Please can I work on the issue

Hi maintainers, I'm Promise Adedokun. I'm a blockchain developer with solid experience working with Stellar, Rust, and building test harnesses for contract-backend consistency. I'd like to work on this consistency test harness. I can create fixture-driven tests comparing indexed backend state with on-chain query results for proposals, votes, streams, and burns including delayed-indexing scenarios and recovery tests. My ETA is 5 hours.

Hello! I would love to fix these pipeline errors. ETA: 2 hours.

Here is my exact plan to resolve the 24 errors and 1 warning:

Syntax Fixes: Resolve the broken JSX/TSX syntax (missing brackets/parentheses and stray tokens) causing parsing errors in App.tsx, AppNav.tsx, and CrossAssetPayment.tsx.

Type Safety: Replace all any types in PayrollScheduler.tsx, VestingGrantForm.tsx, and VestingEscrow.tsx with strict TypeScript interfaces. This will automatically clear the cascade of "unsafe assignment" and "unsafe member access" errors.

Async Handlers: Fix the @typescript-eslint/no-misused-promises errors by safely wrapping the async functions passed to event handlers (e.g., onClick={() => void myAsyncFunc()}).

Cleanup: Remove the unused err variable in VestingEscrow.tsx and add network to the useEffect dependency array in WalletProvider.tsx to clear the exhaustive-deps warning.

I’m interested in tackling this! I have a strong background in smart contract development and full-stack systems, so I'm well-equipped to handle the requirements here. Could you please assign this to me?

Hey maintainers 👋 I’m a blockchain developer with strong expertise in Stellar, Rust,TS and Stellar SDK integrations. I’ve worked on multiple Stellar-based smart contract and backend systems.

I understand the scope of this issue and can deliver a reliable, production-quality solution with proper tests and documentation. And would love to assigned to work on it.

I’d like to work on this issue because it sits at the intersection of system design, financial logic, and secure contract architecture — areas I actively specialize in and enjoy building within. The problem requires careful handling of state transitions, precision math, and security constraints, which makes it both technically meaningful and impactful to the overall reliability of the protocol.

[bitstarkbridge]

I’d like to work on this issue because it directly impacts reliability and developer experience. Problems around deployment, repository configuration, and contract/network mismatches can block contributors entirely, so resolving them has immediate value for both the maintainers and the broader user base. I’m particularly motivated by issues that require careful debugging and clear documentation, since solving them not only fixes the immediate bug but also improves the overall workflow and prevents future regressions.
