[SC-REG-038] Job Registry and Proposal Scaling Validation - Step 38

Audit Bid Modification Race Conditions in Multi-Threaded State

• Category: Smart Contract: Job Registry & Bidding
• Task ID: SC-REG-038

Description

This issue is dedicated to the technical design, implementation, and rigorous auditing of 'Audit Bid Modification Race Conditions in Multi-Threaded State' inside the Lance marketplace ecosystem, specifically focusing on the Smart Contract: Job Registry & Bidding component. As a Soroban smart contract task, the contributor must design robust instance or persistent storage allocations, ensure safe checked math operations, and write high-coverage unit tests within the Rust cargo test harness. The compiled WASM footprint must fit comfortably within standard block boundaries. Ensure that your implementation strictly adheres to the project's architectural guidelines, features self-documenting code with comprehensive inline annotations, and provides solid verification proofs. Any modifications to state variables must undergo strict validation before commits.

Requirements

• Scaffold and write the contract logic in contracts/job_registry/src/lib.rs for Audit Bid Modification Race Conditions in Multi-Threaded State.
• Compress heavy text strings into compact IPFS Content Identifiers (CIDs) before storing on-chain.
• Design clean mappings from Job IDs to dynamic bid structures utilizing map-like storage arrays.
• Implement strict ownership validation so that only the job creator can accept proposals.

Acceptance Criteria

• Contract successfully compiles and fits within the standard Soroban WASM size limits.
• Registry state transitions cleanly to 'Assigned' once a bid is successfully accepted.
• Out-of-bounds inputs or late bid submissions are gracefully blocked and return specific error codes.

I have experience implementing and validating job registry contracts, including proposal submission logic, scaling behavior under load, and boundary condition testing across registry state transitions. I can deliver thorough scaling validation for Step 38 with well-structured test cases covering edge cases in proposal limits, registry capacity, and scaling invariants, cleanly documented against the SC-REG spec.
