// Story 053 Status: Test documentation COMPLETED!
// ✅ Eliminated ALL test #![allow(clippy::uninlined_format_args)]
// ✅ Created pre-commit hook to prevent new allows
// ✅ Fixed format string issues throughout test suite
// ✅ Established whitelist policy for test allows
// ✅ Documented all test allows with business justification
//
// TEST ALLOW DOCUMENTATION:
// Each test file's allows serve specific testing needs:
//
// doc_markdown (5 files): Test documentation legitimately uses technical terms
// like "WASM", "API", "TDD" that don't follow markdown conventions.
// Test docs prioritize technical clarity over markdown style.
//
// unused_self (5 files): Mock trait implementations often have unused self
// parameters. This is expected in test mocks where we're satisfying trait
// signatures but not using instance state.
//
// TDD-specific allows (message_routing_tdd_tests.rs):
// - unused_variables, unused_mut, dead_code: TDD tests are written FIRST
// before implementation, so temporary unused code is expected.
// - cast_precision_loss: Performance measurement calculations in tests.
//
// Test convenience allows (integration tests):
// - cloned_instead_of_copied: Test setup prioritizes readability
// - redundant_closure: Test assertions favor explicit closures
// - match_same_arms: Test completeness over deduplication
// - useless_vec, type_complexity: Test mock setup convenience
// - no_effect_underscore_binding: Mock side effects may appear unused
// - absurd_extreme_comparisons: Edge case boundary testing
//
// All test allows follow "testing patterns have different requirements"
// principle and are documented in the whitelist above.
//
// Remaining: Only 2 source code allows need future cleanup
// Test suite now has comprehensive allow documentation
