Rule: Production Code Only

Purpose

All code merged into main must be production-quality. No demo paths, mock backends, hardcoded test addresses, or in-memory-only persistence should be shipped to production.

Required Behavior

• Prefer production-quality implementations over demo/mock versions.
• When adding a new adapter, it must connect to real infrastructure, not a mock.
• Persistence must use the production storage layer (RocksDB, DB, etc.), not in-memory hashmaps.
• Addresses, keys, and endpoints must be configurable, not hardcoded.
• Feature flags must gate incomplete features — incomplete features must be behind flags.

Forbidden Behavior

• Do NOT ship localhost or 127.0.0.1 as the default production endpoint.
• Do NOT hardcode test private keys in production code.
• Do NOT use HashMap / Vec as permanent storage where a DB is required.
• Do NOT ship mockall, mock_impl, or test-only dependencies in production binaries.
• Do NOT leave #[cfg(test)] workarounds that hide missing production paths.
• Do NOT claim mainnet-readiness with mock RPC endpoints or fake bridge relayers.

Proof Required

• Search for hardcoded test addresses in production source paths.
• Verify production binaries don't link test-only crates.
• Feature flags audit: check that incomplete features are gated.
