Configure Profile Creation and Storage Allocation Safeguards

• Category: Smart Contract: Reputation & Badges
• Task ID: SC-REP-045

Description

This issue is dedicated to the technical design, implementation, and rigorous auditing of 'Configure Profile Creation and Storage Allocation Safeguards' inside the Lance marketplace ecosystem, specifically focusing on the Smart Contract: Reputation & Badges component. To mitigate recursive callback exploits, you must design a robust transient mutex locking guard. The function execution state must transition safely, updating all internal state balances and tracking variables before performing external resource operations or token transfers. 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

• Implement the reputation storage and metrics inside contracts/reputation/src/lib.rs for Configure Profile Creation and Storage Allocation Safeguards.
• Design a custom Profile struct that stores review aggregates, completed jobs count, and active badge levels.
• Implement safe fixed-point arithmetic for averaging ratings and applying mathematical decay factors.
• Secure the score adjustment routines to strictly check that the caller is an authorized contract address.

Acceptance Criteria

• Reputation profiles load and save correctly without panicking on empty accounts.
• Badge upgrades trigger and level changes reflect immediately in the public getters.
• Vulnerability tests prove that arbitrary direct reviews from unverified public keys are rejected.
