V2-FE-082 — Validate Public and Server Environment Variables

[dDevAhmed]

Objective

Validate Public and Server Environment Variables as a focused, independently reviewable V2 frontend work item.

Technical Scope

Schema-check chain IDs, RPC/API origins, manifest versions, feature flags, and analytics settings while preventing secret exposure to bundles.

Security and Architecture Requirements

• Wagmi/Viem and confirmed Optimism/EVM receipts remain authoritative for protocol mutations.
• Never fabricate calldata, gas, rewards, transaction hashes, receipts, settlement, or finality.
• Do not introduce Stellar, Soroban, Freighter, mock-wallet, or simulator runtime dependencies.
• Fail closed on unsupported chain, address, ABI, session, allowance, or configuration state.
• Treat all API, wallet, RPC, claim, and evidence content as untrusted input.

Required Tests

• Unit/component tests for loading, empty, success, rejection, error, and recovery states.
• Wallet/integration coverage for transaction-affecting work.
• Accessibility assertions and keyboard testing for changed interactive UI.
• Regression tests proving mocks and placeholders cannot enter the production bundle.

Acceptance Criteria

• The task is delivered without unrelated visual redesign.
• Every asynchronous state has accurate accessible feedback and recovery.
• Canonical receipts/projections, not timers or client guesses, drive lifecycle state.
• Lint, typecheck, tests, accessibility, artifact-drift, and production build pass.
• The PR maps evidence to every acceptance criterion.
• Human maintainer approval is recorded for wallet/signature/security-sensitive changes.

Dependencies

• V2-FE-042
• V2-FE-043

Non-Goals

• Backend-authoritative protocol mutation.
• Reintroducing legacy wallet/runtime integrations.
• Pure redesign unrelated to the stated workflow.
