[Darkvader-ship-it]

Estimated Effort: 2 weeks / 6 days

Impacted Subsystems / Files:

• lib/profile-store.ts
• components/wallet-avatar.tsx

Context & Problem Statement:
In app/api/profile/avatar/route.ts and associated files lib/profile-store.ts, User profile avatars do not verify true on-chain ownership. Addressing this issue is required to harden system stability, optimize execution speed, and eliminate technical debt across the dApp codebase.

1. Audit execution flow in app/api/profile/avatar/route.ts.
2. Implement isolated domain module in lib/profile-store.ts.
3. Add error boundaries and type-safe schema validation.
4. Write comprehensive automated unit test suite.

Multi-File Change Surface:
Directly alters code logic in app/api/profile/avatar/route.ts, lib/profile-store.ts, and UI wiring in components/wallet-avatar.tsx.

Acceptance Criteria:

• System execution passes performance benchmarks.
• Zero unhandled exception tracebacks in production logs.
• Full unit test pass rate.

Suggested Approach / Investigation Steps:

1. Benchmark target baseline metrics.
2. Implement domain code refactoring.
3. Verify changes end-to-end.
