Branch Isolation Strategy

Confiance : high

Development approach that isolates high-risk feature development in separate branches while maintaining a stable demo path. Essential for time-constrained environments like hackathons where innovation must be balanced with demo reliability.

Core Principles

Risk Segregation

Stable branch: Working demo remains untouched and deployable
Innovation branch: High-risk features developed in isolation
Clear fallback: Predetermined decision point for branch selection
No contamination: Experimental code never touches stable path

Time-Boxing Strategy

# Setup: Create isolated development branch
git checkout stable-demo-branch
git pull
git checkout -b experimental-feature-branch

# Development: All experimental commits go here
git add experimental-files
git commit -m "High-risk feature implementation"
git push origin experimental-feature-branch

# Decision point: Ship experimental or fall back to stable
if experimental_ready_for_demo:
    git checkout experimental-feature-branch
else:
    git checkout stable-demo-branch

Hackathon Application

Example: Wake-Word Detection Implementation

Context: 6 hours until judging, replacing push-to-talk with always-on voice activation

Branch Strategy:

feat/clicky-fork: Working push-to-talk demo (stable)
feat/wakeword-realtime: Wake-word detection (experimental)
Decision criteria: If wake-word ships working, use it; otherwise demo with push-to-talk

Risk Assessment Points:

2 hours in: Core pipeline compiling?
4 hours in: Basic wake-word detection working?
5 hours in: Integration with existing UI stable?
Final hour: Polish vs. fallback decision

Implementation Pattern

// Stable branch: Known working implementation
class CompanionManager {
    func startRecordingFromShortcut() {
        // Proven push-to-talk flow
        dictationManager.startRecording()
    }
}

// Experimental branch: New feature with fallback hooks
class CompanionManager {
    private var wakeWordDetector: WakeWordDetector?
    
    func initializeWakeWordIfAvailable() {
        do {
            wakeWordDetector = try WakeWordDetector()
            wakeWordDetector?.onWakeWordDetected = { [weak self] in
                // Same flow as shortcut, different trigger
                self?.startRecordingFromShortcut()
            }
        } catch {
            // Graceful degradation to shortcut-only mode
            print("Wake-word unavailable, using shortcut only")
        }
    }
}
