Issue Type

Verification - Quality Assurance

Severity

Critical - Final verification before merge

Problem Statement

After implementing Option B (IAudioStrategy + IAudioHardwareProvider consolidation), need to verify all tests pass and output is identical to before refactoring.

Current State

• IAudioStrategy interface consolidated (Implement IAudioStrategy interface consolidation #22)
• IAudioHardwareProvider interface consolidated (Implement IAudioHardwareProvider interface consolidation #24)
• ThreadedStrategy consolidated (Consolidate ThreadedStrategy implementation #26)
• SyncPullStrategy consolidated (Consolidate SyncPullStrategy implementation #28)
• AudioStrategyFactory implemented (Implement AudioStrategyFactory for IAudioStrategy creation #30)
• CLIMain wiring updated (Update CLIMain wiring for IAudioStrategy #32)

Verification Requirements

Build Verification

• Clean build succeeds
• No compiler warnings
• All targets build successfully

Unit Tests

• ThreadedRenderer tests pass (9 tests)
• SyncPullRenderer tests pass (5 tests)
• CircularBuffer tests pass (3 tests)
• All unit tests pass (100% pass rate)

Integration Tests

• Simulator-level tests pass
• Full integration tests pass
• No regressions introduced

Baseline Regression Tests

• ThreadedRenderer baseline comparison passes (output identical)
• SyncPullRenderer baseline comparison passes (output identical)
• All baseline scenarios covered

Smoke Tests

• CLI smoke tests pass
• No underruns in smoke tests
• No crackle or dropouts

Performance Verification

• CPU usage within acceptable range
• Buffer underruns within acceptable range
• No performance regression

Acceptance Criteria

• All verification requirements met
• No failing tests
• No regressions
• Output identical to baseline
• Performance metrics acceptable
• Documentation updated to reflect new architecture
