+### Environment Initialization
+
+The `arc init` command provides an interactive wizard to set up your A.R.C. development environment:
+
+```bash
+arc init
+```
+
+**Features:**
+- 🎮 **Interactive TUI** - Beautiful terminal interface with keyboard navigation
+- 🐉 **Dragon Ball Super Tiers** - Choose from three power levels:
+  - **Super Saiyan**: Standard developer stack (Traefik, Kratos, Postgres, LiveKit)
+  - **Super Saiyan Blue**: Advanced custom orchestration *(Coming Soon)*
+  - **Ultra Instinct**: God-mode with full observability *(Coming Soon)*
+- ⌨️ **Keyboard Navigation** - Use arrow keys (←/→) or vim keys (h/l) to navigate
+- 📁 **Custom Installation Path** - Specify where to initialize your environment
+- ⚡ **Quick Setup** - Complete environment configuration in seconds
+
+**Example Session:**
+```bash
+$ arc init
+
+# Interactive wizard appears:
+# 1. Navigate between tier cards using ← → or h l keys
+# 2. Press Enter to select a tier
+# 3. Enter your desired installation path (default: ./)
+# 4. Watch the animated setup progress
+# 5. Done! Your environment is ready
+
+✓ Setup Complete!
+Stack:    Super Saiyan
+Location: ./my-arc-project
+```
+
+**Note**: The init wizard currently handles the interactive setup flow. Actual file generation and Docker configuration will be available in a future release.
+
 **Available Themes:**
 - `cyan-purple` (default) - Modern & Professional gradient
 - `rainbow` - Full spectrum rainbow

+# Code Quality Review - Feature 007 Init Wizard
+
+**Date**: 2025-12-26
+**Reviewer**: Code Quality Analysis
+**Status**: Phase 10 Complete - Quality Gate Review
+
+## Executive Summary
+
+A comprehensive code quality audit was performed on the Arc CLI codebase following the completion of Feature 007 (Init Wizard). This review identified several critical issues affecting test reliability, code maintainability, and adherence to SOLID/DRY/YAGNI principles.
+
+**Immediate Actions Taken** (Boy Scout Rule Applied):
+- ✅ Fixed critical Makefile test target that was swallowing test failures
+- ✅ Cleaned up duplicate Installation sections in README.md
+- ✅ Removed dead animation code in pkg/ui/service.go (YAGNI violation)
+- ✅ Fixed legacy theme deprecation inconsistency (now uses cyan-purple default)
+
+**Deferred for Future PRs** (documented below):
+- Global init() side effects
+- Missing error propagation in UI service
+
+---
+
+## Critical Issues Fixed
+
+### 1. ✅ Makefile Test Target Swallowing Failures (FIXED)
+
+**Severity**: 🔴 Critical
+**Impact**: Hidden regressions, false positive test results
+
+**Problem**:
+```makefile
+# BEFORE (DANGEROUS)
+test:
+	@go test -v -race $(CORE_PKGS) 2>/dev/null || true  # Always exits 0!
+```
+
+The `2>/dev/null || true` pattern caused the test target to:
+- Silence all error output from race detector
+- Exit with code 0 even when tests fail
+- Hide regressions and race conditions
+- Violate fail-fast principle
+
+**Fix Applied**:
+```makefile
+# AFTER (CORRECT)
+test:
+	@go test -v -race $(CORE_PKGS)  # Fails properly now
+```
+
+**File**: `Makefile` (line 180)
+**Verification**: `make test` now correctly fails on test errors
+
+---
+
+### 2. ✅ README Duplicate Installation Sections (FIXED)
+
+**Severity**: 🟡 Medium
+**Impact**: User confusion, documentation inconsistency
+
+**Problem**:
+- Two separate "## Installation" sections at lines 7 and 111
+- First section for binary releases (end users)
+- Second section for source builds (developers)
+- Caused confusion about installation methods
+
+**Fix Applied**:
+- Merged into single cohesive Installation section
+- Added "From Source (Developers)" subsection
+- Removed duplicate header
+- Added cross-reference to Development section
+
+**Files Modified**: `README.md`
+
+---
+
+### 3. ✅ Dead Animation Code in pkg/ui/service.go (FIXED)
+
+**Severity**: 🟡 Medium
+**Priority**: P2 (COMPLETED)
+**YAGNI Violation**: Yes (RESOLVED)
+
+**Problem**:
+```go
+// service.go - Builder pattern had unused animation flag
+type Builder struct {
+    service  *Service
+    message  string
+    animated bool  // Dead code - never used!
+}
+
+func (b *Builder) Animated() *Builder {
+    b.animated = true  // Sets flag
+    return b          // But nothing reads it!
+}
+```
+
+**Fix Applied**:
+- ✅ Removed `animated` field from Builder struct
+- ✅ Removed `Animated()` method entirely
+- ✅ Removed `TestBuilderAnimated` test for dead code
+- ✅ Cleaned up TODOs in `Do()` and `Print()` methods
+- ✅ Updated godoc to remove animation references
+
+**Files Modified**:
+- `pkg/ui/service.go` - Removed 15 lines of dead code
+- `pkg/ui/service_test.go` - Removed dead test
+
+**Verification**: ✅ All tests pass (pkg/ui: 0.731s)
+
+---
+
+### 4. ✅ Legacy Theme Deprecation Inconsistency (FIXED)
+
+**Severity**: 🟡 Medium
+**Priority**: P2 (COMPLETED)
+**SOLID Violation**: Yes (RESOLVED)
+
+**Problem**:
+```go
+// pkg/cli/root.go - Was still using deprecated legacy theme!
+if !exists {
+    theme = themes.GetLegacyDefault()  // Keeps deprecated code hot
+}
+```
+
+**Fix Applied**:
+```go
+// Now uses default theme from Available() map
+if !exists {
+    // Fallback to default theme (cyan-purple) if configured theme not found
+    theme = allThemes["cyan-purple"]
+}
+```
+
+**Impact**:
+- ✅ Deprecated legacy code no longer in hot path
+- ✅ Consistent with theme system architecture
+- ✅ Can safely remove legacy.go in future cleanup
+- ✅ Better user experience (cyan-purple is better default)
+
+**Files Modified**:
+- `pkg/cli/root.go` (line 48-49)
+
+**Verification**: ✅ All tests pass (pkg/cli: 0.788s)
+
+---
+
+## Issues Documented for Future Action
+
+### 5. Dead Animation Code in pkg/ui/service.go
+
+**Severity**: 🟡 Medium
+**Priority**: P2 (Next Sprint)
+**YAGNI/DRY Violation**: Yes
+
+**Problem**:
+```go
+// service.go - Builder pattern
+func (b *Builder) Animated() *Builder {
+    b.animated = true  // Sets flag
+    return b
+}
+
+// But both Do() and Print() ignore this flag!
+func (b *Builder) Do() error {
+    // TODO: Implement spinner animation  (line ~73)
+    // Currently: animated flag is unused
+}
+
+func (b *Builder) Print() {
+    // TODO: Add animation support  (line ~96)
+    // Currently: animated flag is unused
+}
+```
+
+**Impact**:
+- Misleading API - users expect animation when calling `.Animated()`
+- Dead code violates YAGNI principle
+- TODOs indicate incomplete feature
+- No tests for animation behavior (because it doesn't exist)
+
+**Recommendations**:
+1. **Option A** (Preferred): Remove `Animated()` method and flag until implemented
+2. **Option B**: Implement minimal spinner using existing `pkg/ui/components/spinner.go`
+3. **Option C**: Document as "reserved for future use" and fail fast with panic
+
+**Action Items**:
+- [ ] Decide on implementation approach
+- [ ] Either remove or implement animation
+- [ ] Add tests for chosen behavior
+- [ ] Update `pkg/ui/service_test.go` to cover animation path
+
+**Files Affected**:
+- `pkg/ui/service.go` (lines ~73, 96)
+- `pkg/ui/service_test.go` (missing tests)
+
+---
+
+### 4. Legacy Theme Deprecation Inconsistency
+
+**Severity**: 🟡 Medium
+**Priority**: P2 (Next Sprint)
+**SOLID Violation**: Yes (Open/Closed Principle)
+
+**Problem**:
+```go
+// pkg/ui/themes/legacy.go
+// Package: deprecated legacy theme support
+
+// But pkg/cli/root.go init() still uses it as fallback!
+func init() {
+    // lines ~33-50
+    themeName := state.GetTheme()
+    if themeName == "" || !isValidTheme(themeName) {
+        // Falls back to legacy theme - keeps deprecated code hot!
+        scheme = themes.GetLegacyDefault()
+    }
+}
+```
+
+**Impact**:
+- Deprecated code remains actively used
+- Cannot safely remove legacy theme package
+- Inconsistent messaging to users
+- Hampers migration to new theme system
+
+**Recommendations**:
+1. **Option A**: Document legacy fallback explicitly
+   - Add comment explaining why legacy is still needed
+   - Set timeline for removal
+   - Log deprecation warning to user
+
+2. **Option B**: Remove legacy fallback, fail fast
+   - Use default theme (cyan-purple) instead
+   - Remove `pkg/ui/themes/legacy.go` entirely
+   - Update tests to not reference legacy
+
+**Action Items**:
+- [ ] Decide on deprecation strategy
+- [ ] Either document fallback or remove legacy code
+- [ ] Update `docs/RELEASE_SYSTEM.md` to mention theme migration
+- [ ] Add migration guide if removing legacy support
+
+**Files Affected**:
+- `pkg/ui/themes/legacy.go` (entire package)
+- `pkg/cli/root.go` (init function, lines ~33-50)
+- `pkg/ui/themes/legacy_test.go`
+
+---
+
+### 5. Global Init() Side Effects
+
+**Severity**: 🟡 Medium
+**Priority**: P3 (Technical Debt)
+**SOLID Violation**: Yes (Dependency Inversion, Single Responsibility)
+
+**Problem**:
+```go
+// pkg/cli/root.go
+func init() {
+    // Lines ~21-66
+    // Global side effects before main() runs:
+
+    1. Load preferences from disk
+    2. Mutate package-level styles
+    3. Initialize logging
+    4. Configure theme globally
+
+    // Hard-coupled, difficult to test, hidden dependencies
+}
+```
+
+**Impact**:
+- Testability hampered (global state mutation)
+- Cannot easily mock preferences in tests
+- Violates Dependency Inversion Principle
+- Hidden coupling between packages
+- Makes parallel test execution risky
+
+**Recommendations**:
+1. **Preferred**: Move to explicit bootstrap pattern
+```go
+// cmd/arc/main.go
+func main() {
+    ctx := cli.Bootstrap()  // Explicit initialization
+    rootCmd := cli.NewRootCommand(ctx)
+    rootCmd.Execute()
+}
+```
+
+2. **Benefits**:
+   - Testable: Can inject mock preferences
+   - Explicit: Dependencies are visible
+   - Flexible: Can configure differently per environment
+   - Thread-safe: No global mutation
+
+**Action Items**:
+- [ ] Design explicit bootstrap API
+- [ ] Refactor init() to Bootstrap() function
+- [ ] Update tests to use new pattern
+- [ ] Document initialization flow in `docs/README.md`
+
+**Files Affected**:
+- `pkg/cli/root.go` (init function)
+- `cmd/arc/main.go` (needs Bootstrap call)
+- All tests in `pkg/cli/*_test.go`
+
+---
+
+### 6. Missing Error Propagation in UI Service
+
+**Severity**: 🟢 Low
+**Priority**: P4 (Nice-to-Have)
+
+**Problem**:
+```go
+// pkg/ui/service.go
+func (s *Service) Success(message string) {
+    fmt.Fprintln(s.writer, styled)  // Ignores error
+}
+
+func (s *Service) Error(message string) {
+    fmt.Fprintln(s.writer, styled)  // Ignores error
+}
+```
+
+**Impact**:
+- Silent failures if writer encounters error
+- Not critical for TTY but problematic for file/pipe output
+- Could hide important diagnostic information
+
+**Recommendations**:
+1. Add error returns to Service methods
+2. Log errors internally if critical
+3. Consider builder pattern for error handling preference
+
+**Action Items**:
+- [ ] Audit all `fmt.Fprintln` calls in service.go
+- [ ] Decide on error handling strategy
+- [ ] Add tests for error cases
+- [ ] Document error behavior
+
+**Files Affected**:
+- `pkg/ui/service.go` (all print methods)
+
+---
+
+### 7. Test Coverage Gaps
+
+**Severity**: 🟢 Low
+**Priority**: P3
+
+**Missing Tests**:
+1. `pkg/ui/service_test.go`:
+   - No log emission assertions
+   - No spinner behavior tests (because unimplemented)
+   - No error case coverage
+
+2. Animation path completely untested:
+   - `Builder.Animated()` has no tests
+   - No validation that animation works (because it doesn't)
+
+**Recommendations**:
+- Add tests once animation behavior is defined (Issue #3)
+- Add error case tests for writer failures
+- Mock writer to verify exact output
+
+---
+
+## Documentation Updates Needed
+
+### 1. docs/TESTING.md
+**Current**: States "lenient testing" 60-70% coverage
+**Reality**: Makefile enforces 70% hard threshold with race
+**Action**: Document actual threshold and CLI pkg race exclusion
+
+### 2. docs/RELEASE_SYSTEM.md
+**Current**: No mention of theme deprecation
+**Action**: Document legacy theme fallback if keeping, or removal timeline
+
+### 3. docs/CI_CD_SETUP.md
+**Current**: No documentation of test failure expectations
+**Action**: Document that tests must fail properly (Makefile now fixed)
+
+### 4. docs/README.md
+**Current**: No mention of bootstrap flow
+**Action**: Document preference/theme loading and init() behavior
+
+---
+
+## DRY/SOLID/YAGNI Summary
+
+### Violations Found:
+
+**YAGNI** (You Aren't Gonna Need It):
+- ❌ Dead animation flag in service.go (implemented but unused)
+- ❌ Legacy theme kept "just in case" despite deprecation
+
+**DRY** (Don't Repeat Yourself):
+- ⚠️ Duplicate Installation sections in README (FIXED)
+- ⚠️ Theme loading logic scattered across init() and state package
+
+**SOLID Principles**:
+- ❌ **Single Responsibility**: init() does too much (load, configure, mutate)
+- ❌ **Open/Closed**: Legacy theme violates - must modify to remove
+- ❌ **Dependency Inversion**: root.go depends on concrete state implementation
+- ✅ **Interface Segregation**: Good - interfaces are focused
+- ✅ **Liskov Substitution**: Good - no violations found
+
+---
+
+## Immediate Next Steps
+
+### For Current PR (007-init-wizard):
+- ✅ Makefile test fix (DONE)
+- ✅ README cleanup (DONE)
+- ✅ Document findings in this file (DONE)
+- ✅ Remove dead animation code (DONE - Boy Scout Rule)
+- ✅ Fix legacy theme deprecation (DONE - Boy Scout Rule)
+- ✅ Update tasks.md to mark Phase 10 complete (DONE)
+
+### For Follow-up Issues:
+1. ~~**Issue**: Remove dead animation code or implement spinner~~ ✅ FIXED IN THIS PR
+   - Priority: P2
+   - Status: COMPLETED
+   - Files: `pkg/ui/service.go`, `pkg/ui/service_test.go`
+
+2. ~~**Issue**: Resolve legacy theme deprecation~~ ✅ FIXED IN THIS PR
+   - Priority: P2
+   - Status: COMPLETED
+   - Files: `pkg/cli/root.go`
+
+3. **Issue**: Refactor global init() to explicit Bootstrap
+   - Priority: P3
+   - Effort: 4-6 hours (includes test updates)
+   - Files: `pkg/cli/root.go`, `cmd/arc/main.go`, all tests
+
+4. **Issue**: Add error propagation to UI service
+   - Priority: P4
+   - Effort: 2 hours
+   - Files: `pkg/ui/service.go`, tests
+
+---
+

+# Specification Quality Checklist: Arc Init Wizard
+
+**Purpose**: Validate specification completeness and quality before proceeding to planning
+**Created**: 2025-12-25
+**Feature**: [spec.md](../spec.md)
+**Status**: ✅ PASSED - Ready for planning phase
+
+## Content Quality
+
+- [x] No implementation details (languages, frameworks, APIs)
+  - ✅ PASS: Spec describes behavior and UI/UX without mentioning Go, Bubble Tea implementation details, or specific package structures
+- [x] Focused on user value and business needs
+  - ✅ PASS: Each user story emphasizes developer needs (quick scaffolding, exploration, keyboard navigation)
+- [x] Written for non-technical stakeholders
+  - ✅ PASS: Language is accessible, uses metaphors (Dragon Ball Super tiers), focuses on user experience
+- [x] All mandatory sections completed
+  - ✅ PASS: Feature Overview, User Scenarios, Requirements, Success Criteria all present and complete
+
+## Requirement Completeness
+
+- [x] No [NEEDS CLARIFICATION] markers remain
+  - ✅ PASS: All clarifications from Q1-Q3 were resolved before spec creation
+- [x] Requirements are testable and unambiguous
+  - ✅ PASS: All FR requirements specify exact behavior (e.g., "MUST display three tier cards", "MUST simulate for 2-3 seconds")
+- [x] Success criteria are measurable
+  - ✅ PASS: All SC criteria include specific metrics (30 seconds, 50ms response, 90% completion rate)
+- [x] Success criteria are technology-agnostic (no implementation details)
+  - ✅ PASS: SC criteria focus on user-observable outcomes (completion time, visual feedback, navigation success)
+- [x] All acceptance scenarios are defined
+  - ✅ PASS: Each user story includes Given/When/Then scenarios covering primary and edge cases
+- [x] Edge cases are identified
+  - ✅ PASS: 7 edge cases documented (narrow terminal, small height, rapid keys, color support, interruption, etc.)
+- [x] Scope is clearly bounded
+  - ✅ PASS: Feature Overview explicitly states "focuses purely on UI/UX flow and visual presentation. Actual file generation and Docker configuration are deferred to a future phase"
+- [x] Dependencies and assumptions identified
+  - ✅ PASS: 8 assumptions documented covering terminal capabilities, package dependencies, and deferred work
+
+## Feature Readiness
+
+- [x] All functional requirements have clear acceptance criteria
+  - ✅ PASS: 36 FR requirements map directly to acceptance scenarios in user stories
+- [x] User scenarios cover primary flows
+  - ✅ PASS: 4 prioritized user stories cover happy path (P1), exploration (P2), keyboard navigation (P2), and custom paths (P3)
+- [x] Feature meets measurable outcomes defined in Success Criteria
+  - ✅ PASS: 10 SC criteria directly correspond to FR requirements and user stories
+- [x] No implementation details leak into specification
+  - ✅ PASS: Mentions of `internal/branding`, `pkg/ui/components`, and `lipgloss.Color` are appropriate references to existing architecture, not implementation instructions
+
+## Validation Summary
+
+**Result**: ✅ ALL CHECKS PASSED
+
+**Assessment**: This specification is complete, unambiguous, and ready for the planning phase. It successfully balances technical clarity with user-focused language. The Dragon Ball Super metaphor is well-integrated throughout, making the spec engaging while remaining professional.
+
+**Strengths**:
+- Clear prioritization (P1-P3) enables phased implementation
+- Edge cases anticipate real-world terminal environment variations
+- Success criteria mix quantitative metrics (time, response) with qualitative goals (UX)
+- Assumptions document deferred work explicitly, preventing scope creep
+
+**Ready for**: `/speckit.plan` to break down into implementation tasks
+
+## Notes
+
+No spec updates required. Proceed to planning phase.

+// Package contracts defines interfaces for the Arc Init Wizard.
+// These are design-time contracts (not executable Go code).
+// Implementation will be in pkg/cli/init.go
+package contracts
+
+import "context"
+
+// InitOperation represents an initialization operation (file generation, network fetch, etc.)
+//
+// Design Principles:
+//   - Async execution with progress callbacks (no polling)
+//   - Context-based cancellation (Ctrl+C support)
+//   - Validation before execution (fail fast)
+//   - Descriptive for logging and error messages
+//
+// Implementations:
+//   - MockInitOperation (Phase 1): Simulates I/O with time delays
+//   - DockerComposeOperation (Future): Generates docker-compose.yml
+//   - EnvFileOperation (Future): Generates .env files
+//   - NetworkFetchOperation (Future): Downloads templates from GitHub
+//
+// Usage Example:
+//
+//	operation := &MockInitOperation{tier: superSaiyan, path: "./"}
+//	if err := operation.Validate(); err != nil {
+//	    return err
+//	}
+//	err := operation.Execute(ctx, func(state InstallState, progress float64) {
+//	    // Update UI with progress
+//	    fmt.Printf("%s: %.0f%%\n", state.Message(), progress*100)
+//	})
+type InitOperation interface {
+	// Execute runs the operation asynchronously with progress callbacks.
+	//
+	// Parameters:
+	//   ctx: Context for cancellation. MUST be respected - check ctx.Done() regularly.
+	//   onProgress: Callback invoked on state changes and progress updates.
+	//               Signature: func(state InstallState, progress float64)
+	//               - state: Current operation phase (Validating, Downloading, etc.)
+	//               - progress: Percentage complete (0.0 to 1.0)
+	//
+	// Guarantees:
+	//   - MUST call onProgress() at least once per InstallState
+	//   - MUST respect ctx.Done() for cancellation (return ctx.Err())
+	//   - Progress values MUST be monotonically increasing
+	//   - StateComplete MUST always have progress = 1.0
+	//
+	// Returns:
+	//   - nil on success
+	//   - error if operation fails or is canceled
+	//
+	// Example:
+	//   err := operation.Execute(ctx, func(state InstallState, progress float64) {
+	//       model.installState = state
+	//       model.installProgress = progress
+	//   })
+	Execute(ctx context.Context, onProgress func(InstallState, float64)) error
+
+	// Validate checks if operation prerequisites are met before execution.
+	//
+	// Checks (implementation-dependent):
+	//   - Path is writable (permissions)
+	//   - Sufficient disk space available
+	//   - Network connectivity (if required)
+	//   - Required CLI tools installed (docker, docker-compose)
+	//   - Templates/resources exist
+	//
+	// Guarantees:
+	//   - MUST be idempotent (safe to call multiple times)
+	//   - MUST be fast (< 100ms) - no network I/O
+	//   - MUST NOT modify any state (read-only check)
+	//
+	// Returns:
+	//   - nil if all prerequisites met
+	//   - error describing validation failure (user-facing message)
+	//
+	// Example:
+	//   if err := operation.Validate(); err != nil {
+	//       return fmt.Errorf("cannot proceed: %w", err)
+	//   }

+# Data Model: Arc Init Wizard
+
+**Phase**: 1 (Design & Contracts)
+**Date**: 2025-12-25
+**Plan**: [plan.md](./plan.md)
+
+## Overview
+
+This document defines the core data entities and their relationships for the Arc Init Wizard. All entities are technology-agnostic (no Go-specific implementation details).
+
+---
+
+## Entity: StackTier
+
+**Description**: Represents a platform stack complexity level using the Dragon Ball Super metaphor. Each tier defines a collection of services with minimum resource requirements.
+
+### Attributes
+
+| Attribute | Type | Required | Constraints | Description |
+|-----------|------|----------|-------------|-------------|
+| `ID` | string | Yes | Lowercase kebab-case, unique | Unique identifier (e.g., "super-saiyan") |
+| `Name` | string | Yes | Non-empty, display-friendly | Human-readable tier name (e.g., "Super Saiyan") |
+| `Description` | string | Yes | 1-2 sentences | Brief explanation of tier purpose |
+| `Services` | list<string> | Yes | May be empty for disabled tiers | List of included service names |
+| `MinCPU` | integer | Yes | > 0 for enabled tiers | Minimum CPU cores required |
+| `MinRAM` | integer | Yes | > 0 for enabled tiers | Minimum RAM in gigabytes |
+| `Enabled` | boolean | Yes | true or false | Whether tier is selectable in wizard |
+| `Color` | color | Yes | Valid hex color code | Visual theme color for UI rendering |
+
+### Validation Rules
+
+1. **ID Format**: Must match regex `^[a-z0-9]+(-[a-z0-9]+)*$`
+2. **Name Uniqueness**: No two tiers can have the same Name
+3. **Enabled Tiers**: If `Enabled = true`, then `MinCPU > 0` and `MinRAM > 0`
+4. **Disabled Tiers**: If `Enabled = false`, Services list MAY be empty (placeholder for future)
+5. **Color Format**: Must be valid hex color (`#RRGGBB` format)
+
+### Instances (Constants)

+
+---
+
+#### Ultra Instinct (Coming Soon)
+
+- **ID**: `"ultra-instinct"`
+- **Name**: `"Ultra Instinct"`
+- **Description**: `"God-mode stack with full observability, distributed tracing, and advanced scaling. (Under development)"`
+- **Services**: `[]` (empty - to be defined)

+
+---
+
+### Relationships
+
+- **StackTier → Services**: One tier includes many services (one-to-many)

+
+---
+
+## Entity: WizardState
+
+**Description**: Represents the ephemeral state of the wizard session. Exists only in memory during wizard execution (not persisted to disk).
+

+
+### Lifecycle
+
+1. **Creation**: Wizard starts, `initialWizardState()` called
+2. **Updates**: State mutated in response to keyboard input, timer events
+3. **Destruction**: Wizard exits, state discarded (no persistence)
+
+### Validation Rules
+
+1. **SelectedTierIndex Bounds**: Must be in range `[0, len(Tiers)-1]`
+2. **InstallPath Non-Empty**: When transitioning to Installation, `InstallPath != ""`
+3. **Terminal Minimum**: `TermWidth >= 80 AND TermHeight >= 20` (or show warning)
+4. **Progress Bounds**: `InstallProgress` must be in range `[0.0, 1.0]`
+
+---
+
+## Entity: InstallState
+
+**Description**: Represents granular installation progress stages. Maps to user-facing messages and progress percentages.
+
+### Values
+
+| State | Numeric Value | Progress Range | Description |
+|-------|---------------|----------------|-------------|
+| `Validating` | 0 | 0% - 20% | Checking prerequisites, validating path |
+| `Downloading` | 1 | 20% - 40% | Fetching templates or images |
+| `Configuring` | 2 | 40% - 60% | Generating configuration files |
+| `Writing` | 3 | 60% - 80% | Writing files to disk |
+| `Complete` | 4 | 80% - 100% | Installation finished |
+
+### State Messages
+
+Each state has an associated user-facing message displayed during installation:
+
+| State | Message |
+|-------|---------|
+| `Validating` | "Validating installation path..." |
+| `Downloading` | "Downloading configuration templates..." |
+| `Configuring` | "Generating docker-compose.yml..." |
+| `Writing` | "Writing configuration files..." |
+| `Complete` | "Setup complete!" |
+
+### Progress Calculation
+
+```
+Progress Percentage = (State Value + 1) / Total States
+  where Total States = 5
+
+Examples:
+  Validating  (0): (0 + 1) / 5 = 0.20 (20%)
+  Downloading (1): (1 + 1) / 5 = 0.40 (40%)
+  Configuring (2): (2 + 1) / 5 = 0.60 (60%)
+  Writing     (3): (3 + 1) / 5 = 0.80 (80%)
+  Complete    (4): (4 + 1) / 5 = 1.00 (100%)
+```
+
+### Transition Rules
+
+1. **Sequential**: States must progress in order (no skipping)
+2. **Monotonic**: Progress must always increase (never decrease)
+3. **Final State**: `Complete` is terminal (no further states)
+
+---
+
+## Entity: InitOperationResult
+
+**Description**: Represents the outcome of an installation operation (future phase - not implemented yet).
+
+### Attributes
+
+| Attribute | Type | Required | Description |
+|-----------|------|----------|-------------|
+| `Success` | boolean | Yes | Whether operation completed successfully |
+| `Error` | string | No | Error message if `Success = false` |
+| `FilesCreated` | list<string> | No | Paths of files written to disk |
+| `DurationMs` | integer | Yes | Operation duration in milliseconds |
+| `Tier` | StackTier | Yes | Which tier was installed |
+| `Path` | string | Yes | Where files were installed |
+
+**Note**: Not used in Phase 1 (UI-only). Will be added when real I/O operations implemented.

+# Implementation Plan: Arc Init Wizard
+
+**Branch**: `007-init-wizard` | **Date**: 2025-12-25 | **Spec**: [spec.md](./spec.md)
+**Input**: Feature specification from `/specs/007-init-wizard/spec.md`
+
+**Note**: This plan follows the `/speckit.plan` workflow with enhanced Charmbracelet components and I/O abstraction architecture.
+
+## Summary
+
+The `arc init` wizard provides an interactive TUI for platform stack selection using the Dragon Ball Super tiering metaphor. This implementation focuses on:
+
+1. **Modern TUI Components**: Leverage Charmbracelet ecosystem (`bubbles/list`, `bubbles/progress`, `bubbles/viewport`) for Claude-like UX
+2. **I/O Abstraction Layer**: Interface-based design with mock implementations for async file/network operations
+3. **Theme Integration**: Hybrid approach - fixed tier colors for branding, active theme for UI chrome
+4. **Multi-step Progress**: 5-state installation flow (Validating → Downloading → Configuring → Writing → Complete)
+5. **Expandable Architecture**: Interface-based wizard steps supporting future enhancements without refactoring
+
+**Technical Approach**:
+- Use `bubbles/list` for tier selection (replaces manual card rendering)
+- Use `bubbles/progress` for installation progress tracking
+- Use `bubbles/textinput` for path entry with validation
+- Create `InitOperation` interface for I/O abstraction (file writes, network calls)
+- Implement `MockInitOperation` for this phase (real implementations deferred)
+- Load active theme from `internal/preferences` for borders, backgrounds, and text
+
+## Technical Context
+
+**Language/Version**: Go 1.24.0
+**Primary Dependencies**:
+- `github.com/charmbracelet/bubbletea` v1.3.4 (TUI framework)
+- `github.com/charmbracelet/bubbles` v0.21.0 (TUI components: list, progress, textinput)
+- `github.com/charmbracelet/lipgloss` v1.1.1 (styling)
+- `github.com/spf13/cobra` v1.10.2 (CLI framework)
+
+**Storage**: N/A (no persistence in this phase, state held in memory during wizard execution)
+
+**Testing**:
+- Go testing framework with `testify/assert` and `testify/require`
+- Table-driven tests for state transitions
+- Snapshot testing for rendered output (optional)
+- Mock Bubble Tea messages for Update() method testing
+
+**Target Platform**: Cross-platform CLI (macOS, Linux, Windows) with terminal emulator support (ANSI escape codes)
+
+**Project Type**: Single project (CLI application)
+
+**Performance Goals**:
+- Keyboard input response < 50ms (immediate visual feedback)
+- Screen renders < 100ms (smooth transitions)
+- Wizard completion < 30 seconds (full user flow)
+- Terminal size detection < 10ms
+
+**Constraints**:
+- Minimum terminal size: 80 columns × 20 rows
+- Zero external runtime dependencies (Go binary only)
+- Fully offline capable (no network required for UI)
+- Support color and non-color terminals (graceful fallback)
+
+**Scale/Scope**:
+- Single-user interactive session (no concurrency concerns)
+- 4 wizard steps (StackSelection, PathSelection, Installation, Completion)
+- 3 tier definitions (Super Saiyan, Super Saiyan Blue, Ultra Instinct)
+- 5 installation states (Validating, Downloading, Configuring, Writing, Complete)
+
+## Constitution Check
+
+*GATE: Must pass before Phase 0 research. Re-check after Phase 1 design.*
+
+Verify compliance with A.R.C. CLI Constitution principles (v1.1.0):
+
+- [x] **Zero-Dependency**: ✅ COMPLIANT - Uses only Go standard library and embedded dependencies (Bubble Tea, Lipgloss, Cobra already in go.mod). No external runtime dependencies introduced.
+- [x] **Local-First**: ✅ COMPLIANT - Wizard operates entirely offline. No network access required for UI flow. File I/O operations (deferred to future phase) will be local only.
+- [x] **Two-Brain Separation**: ✅ COMPLIANT - CLI provides infrastructure setup wizard. No agent reasoning or business logic implemented. Wizard orchestrates environment setup, not agent behavior.
+- [x] **Platform-in-a-Box**: ✅ COMPLIANT - Interactive tier selection with visual prompts. Future phase will implement "pull images OR generate configs" decisions. Seamless developer experience maintained.
+- [x] **Intelligent Orchestration**: ⚠️ PARTIAL (acceptable for this phase) - State tracked in-memory during wizard session. Full state persistence (embedded DB) deferred to implementation phase when real I/O operations added.
+- [x] **Deep Observability**: ✅ COMPLIANT - Multi-step progress tracking (5 states) provides visibility beyond simple spinner. Future phase will add detailed diagnostics per operation.
+- [x] **Resilience Testing**: ✅ COMPLIANT - Edge cases documented (terminal size, color support, interruption). State machine transitions testable with mock messages.
+- [x] **Interactive Experience**: ✅ COMPLIANT - Rich TUI with progress bars, spinners, and real-time feedback. `--json` fallback not required for interactive-only wizard (could be added later).
+- [x] **Declarative Reconciliation**: ⚠️ PARTIAL (acceptable for this phase) - Wizard generates initial configuration. `arc.yaml` management and drift detection deferred to future phases.
+- [x] **Security by Default**: ✅ COMPLIANT - No secrets generated in this phase. Future implementation will use high-entropy secret generation. Path selection includes validation (future phase).
+- [x] **Stateful Operations**: ⚠️ PARTIAL (acceptable for this phase) - In-memory state during wizard session. Embedded DB tracking deferred to implementation phase when real operations added.
+- [x] **High-Performance I/O**: ✅ COMPLIANT - I/O abstraction layer designed for async operations. Mock implementations in this phase. Fast terminal rendering (<100ms) using lipgloss caching.
+
+**Violations requiring justification**: None - all partial compliance items are explicitly deferred to implementation phase per spec scope
+
+| Principle Violated | Justification | Mitigation |
+|-------------------|---------------|------------|
+| N/A               | N/A           | N/A        |
+
+## Architectural Patterns Compliance
+
+*GATE: Must pass for specs 006+. Specs 001-005 are grandfathered.*
+
+Verify compliance with Arc CLI Architectural Patterns (v1.0.0):
+Reference: `.specify/memory/patterns.md`
+
+**Note**: Spec 007 MUST comply with all patterns.
+
+### 1. Factory Pattern (Dependency Injection)
+- [x] **No Global State**: ✅ COMPLIANT - No package-level `var` for logger or state. All state encapsulated in `initModel` struct passed through Bubble Tea lifecycle.
+- [x] **Context Injection**: ✅ COMPLIANT - Cobra command receives app context. Theme loaded from `internal/preferences` via context.
+- [x] **Explicit Dependencies**: ✅ COMPLIANT - Spinner, theme, and version dependencies injected during model initialization.
+
+### 2. XDG Base Directory Specification
+- [x] **Config Location**: ✅ COMPLIANT - Reads active theme from `~/.config/arc/` via `internal/preferences.Load()`. No new config files created.
+- [x] **Data Location**: ⚠️ DEFERRED - File generation deferred to future phase. Will use `~/.local/share/arc/` for generated configs.
+- [x] **State Location**: ⚠️ DEFERRED - Operation logging deferred to future phase. Will use `~/.local/state/arc/` for wizard history.
+- [x] **XDG Functions**: ✅ COMPLIANT - Uses `internal/xdg` package for path resolution (already implemented in codebase).
+
+### 3. Repository Pattern (Domain-Driven Storage)
+- [x] **Interface Per Domain**: ⚠️ DEFERRED - No persistent storage in this phase. Future: `InitOperationRepository` interface for wizard state tracking.
+- [x] **Interface Location**: N/A - No repository interfaces needed for in-memory wizard state.
+- [x] **Implementation Location**: N/A - Mock I/O operations in `pkg/cli/init.go` (no separate storage layer yet).
+- [x] **No Direct File Access**: ✅ COMPLIANT - I/O abstraction interfaces defined (`InitOperation`). Mock implementations only in this phase.
+
+### 4. Middleware/UI Service Pattern
+- [x] **UI Service**: ✅ COMPLIANT - Uses Bubble Tea rendering pipeline (built-in UI service). Theme styles loaded from active preferences.
+- [x] **No Flag Checks**: ✅ COMPLIANT - No direct flag checks. Wizard operates in interactive mode (flags not applicable for TUI wizard).
+- [x] **Separation of Concerns**: ✅ COMPLIANT - View rendering separated from business logic (Update() vs View() methods). Theme styles abstracted.
+
+### 5. Configuration Management (12-Factor App)
+- [x] **Environment Support**: ⚠️ NOT APPLICABLE - Wizard is interactive-only. No environment variable configuration needed for UI flow.
+- [x] **Precedence Chain**: N/A - No configuration precedence in wizard (user makes explicit choices via UI).
+- [x] **Unified Config**: ✅ COMPLIANT - Reads active theme via `internal/preferences` (unified config system).
+
+### 6. Testing Standards
+- [x] **Table-Driven Tests**: ✅ PLANNED - Tasks include table-driven tests for state transitions, terminal sizes, keyboard navigation.
+- [x] **Parallel Execution**: ✅ PLANNED - All tests marked with `t.Parallel()` where safe (no shared state).
+- [x] **Coverage Target**: ✅ PLANNED - Targets: State machine 75%, navigation 80%, footer 80%, rendering 40%.
+
+**Pattern Exceptions** (if any):
+
+| Pattern | Exception Reason | Mitigation |
+|---------|------------------|------------|
+| Repository Pattern (partial) | No persistent storage in Phase 1 (UI-only) | I/O abstraction interfaces defined. Repository pattern will be added when file generation implemented in future phase. |
+| Environment Variables (N/A) | Interactive wizard doesn't use env config | Acceptable - wizard is user-driven via TUI, not configuration-driven. Future `arc init --tier=<name>` flag could use env vars. |
+
+**Reference Implementations**:
+- Bubble Tea TUI: Existing `pkg/cli/info.go` (reference implementation)
+- Theme Integration: `internal/preferences.Load()` → `pkg/ui/themes.Available()`
+- Spinner Component: `pkg/ui/components.NewSpinner()`

+
+**Structure Decision**:
+
+- **Single-file implementation**: All wizard code in `pkg/cli/init.go` (co-located with other CLI commands)
+- **Test co-location**: `pkg/cli/init_test.go` follows Go conventions
+- **No new packages**: Leverages existing `internal/` and `pkg/ui/` infrastructure
+- **Future extensibility**: I/O operations will be extracted to `pkg/init/operations/` when real implementations added
+
+**Rationale**: Keeping wizard logic in `pkg/cli/` maintains consistency with existing commands (`info`, `help`, etc.). The I/O abstraction interface is defined in the same file initially, then can be extracted to `contracts/` or a separate package when multiple implementations exist (pragmatic plugin approach per user's preference).

+
+## Phase 0: Outline & Research
+
+**Goal**: Resolve technical unknowns and document component choices
+
+### Research Tasks
+
+#### R1: Charmbracelet Components Selection
+
+**Question**: Which `bubbles` components best fit the wizard UX requirements?
+
+**Research Findings**:
+
+1. **`bubbles/list`** for Tier Selection
+   - **Decision**: Use `list.Model` with custom delegate for tier cards
+   - **Rationale**: Provides built-in keyboard navigation, selection state, and viewport scrolling
+   - **Alternative Considered**: Manual card rendering with lipgloss
+   - **Rejected Because**: Reinvents navigation logic, harder to maintain, no accessibility features
+
+2. **`bubbles/progress`** for Installation Progress
+   - **Decision**: Use `progress.Model` with 5-step state tracking (0% → 20% → 40% → 60% → 80% → 100%)
+   - **Rationale**: Visual feedback for multi-step operations, smooth animations, percentage display
+   - **Alternative Considered**: Simple spinner with text updates
+   - **Rejected Because**: Less informative, no sense of progress through stages
+
+3. **`bubbles/textinput`** for Path Entry
+   - **Decision**: Use `textinput.Model` with validation callback
+   - **Rationale**: Built-in cursor management, character input, backspace handling
+   - **Alternative Considered**: Manual rune handling in Update() method
+   - **Rejected Because**: Complex edge cases (UTF-8, cursor position, copy/paste)
+
+4. **`bubbles/viewport`** for Coming Soon Modal
+   - **Decision**: Use `viewport.Model` for scrollable modal content (future tiers may have long descriptions)
+   - **Rationale**: Handles content overflow, keyboard scrolling, future-proof
+   - **Alternative Considered**: Fixed-size lipgloss box
+   - **Rejected Because**: No scrolling if content exceeds terminal height
+
+**Adoption Pattern**:
+```go
+// Tier selection using list
+tierList := list.New(tierItems, tierDelegate{}, width, height)
+tierList.SetShowStatusBar(false)
+tierList.SetFilteringEnabled(false)
+
+// Installation progress
+installProgress := progress.New(progress.WithDefaultGradient())
+installProgress.Width = 40
+
+// Path input
+pathInput := textinput.New()
+pathInput.Placeholder = "./"
+pathInput.CharLimit = 256
+```
+
+---
+
+#### R2: Theme Integration Strategy
+
+**Question**: How to balance fixed Dragon Ball tier colors with user theme preferences?
+
+**Research Findings**:
+
+**Decision**: Hybrid approach - tier colors fixed, UI chrome themed
+
+**Rationale**:
+- Dragon Ball colors (#FFD700 Gold, #00BFFF Blue, #E6E6FA Lavender) are part of the feature's identity
+- Changing tier colors based on theme would break the metaphor
+- UI elements (borders, footer, modal) should respect user preferences for consistency
+
+**Implementation**:
+```go
+// Load active theme
+appState, _ := preferences.Load()
+themeName := appState.GetTheme()
+theme := themes.Available()[themeName]
+
+// Apply to UI chrome
+borderStyle := lipgloss.NewStyle().
+    BorderStyle(lipgloss.RoundedBorder()).
+    BorderForeground(theme.BorderColor) // From theme
+
+// Keep tier colors fixed
+superSaiyanColor := lipgloss.Color("#FFD700") // Always gold
+```
+
+**Theme Elements**:
+- Border colors: From active theme
+- Text colors: From active theme (primary, secondary, muted)
+- Background colors: From active theme (if supported)
+- Tier card colors: Fixed (override theme)

+#### R3: I/O Abstraction Interface Design
+
+**Question**: How to structure I/O operations for future real implementations?
+
+**Research Findings**:
+
+**Decision**: `InitOperation` interface with state callback pattern
+
+**Interface Design**:
+```go
+// InitOperation represents an async initialization operation
+type InitOperation interface {
+    // Execute runs the operation with progress callbacks
+    Execute(ctx context.Context, onProgress func(InstallState, float64)) error
+
+    // Validate checks if operation can proceed (prerequisites met)
+    Validate() error
+
+    // Description returns human-readable operation description
+    Description() string
+}
+
+// InstallState represents installation progress states
+type InstallState int
+
+const (
+    StateValidating InstallState = iota  // 0-20%
+    StateDownloading                      // 20-40%
+    StateConfiguring                      // 40-60%
+    StateWriting                          // 60-80%
+    StateComplete                         // 80-100%
+)
+```
+
+**Mock Implementation** (this phase):
+```go
+type MockInitOperation struct {
+    tier StackTier
+    path string
+}
+
+func (m *MockInitOperation) Execute(ctx context.Context, onProgress func(InstallState, float64)) error {
+    states := []InstallState{StateValidating, StateDownloading, StateConfiguring, StateWriting, StateComplete}
+    for i, state := range states {
+        select {
+        case <-ctx.Done():
+            return ctx.Err()
+        case <-time.After(500 * time.Millisecond):
+            progress := float64(i+1) / float64(len(states))
+            onProgress(state, progress)
+        }
+    }
+    return nil
+}
+```
+
+**Real Implementation** (future phase):
+```go
+type DockerComposeOperation struct {
+    tier StackTier
+    path string
+    templateEngine *template.Engine
+}
+
+func (d *DockerComposeOperation) Execute(ctx context.Context, onProgress func(InstallState, float64)) error {
+    // Actual file generation logic
+    onProgress(StateValidating, 0.2)
+    // Validate path, check disk space
+
+    onProgress(StateDownloading, 0.4)
+    // Fetch Docker Compose templates
+
+    onProgress(StateConfiguring, 0.6)
+    // Generate docker-compose.yml from template
+
+    onProgress(StateWriting, 0.8)
+    // Write files to disk
+
+    onProgress(StateComplete, 1.0)
+    return nil
+}
+```
+
+**Rationale**:
+- Callback pattern allows UI to update in real-time without polling
+- Context enables cancellation (Ctrl+C during install)
+- Progress percentage maps directly to `bubbles/progress` model
+- Interface allows swapping mock → real without changing wizard code
+
+---
+
+#### R4: Terminal Size Responsiveness
+
+**Question**: How to handle varying terminal dimensions gracefully?
+
+**Research Findings**:
+
+**Decision**: Viewport-based responsive layout with minimum threshold
+
+**Layout Strategy**:
+
+| Terminal Width | Layout Behavior |
+|---------------|-----------------|
+| < 80 cols     | Show warning: "Terminal too small. Please resize to at least 80x20." |
+| 80-120 cols   | Compact mode - stack tier cards vertically if horizontal space insufficient |
+| > 120 cols    | Full horizontal card layout with rich formatting |
+
+**Height Handling**:
+
+| Terminal Height | Layout Behavior |
+|----------------|-----------------|
+| < 20 rows      | Show warning (same as width) |
+| 20-30 rows     | Compact banner, minimal padding |
+| > 30 rows      | Full banner, generous padding |
+
+**Implementation**:
+```go
+func (m *initModel) View() string {
+    width, height, _ := term.GetSize(int(os.Stdout.Fd()))
+    m.termWidth = width
+    m.termHeight = height
+
+    if width < 80 || height < 20 {
+        return m.renderTerminalTooSmall()
+    }
+
+    // Dynamic layout based on dimensions
+    // ...
+}
+```
+
+---
+
+### Research Output
+
+Create `research.md` documenting:
+1. Component choices (list, progress, textinput, viewport)
+2. Theme integration approach (hybrid - fixed tier colors, themed UI chrome)
+3. I/O abstraction interface design (callback pattern, context cancellation)
+4. Responsive layout strategy (viewport thresholds, fallback rendering)
+
+All NEEDS CLARIFICATION items from Technical Context are now resolved.
+
+---
+
+## Phase 1: Design & Contracts
+
+**Goal**: Define data models, API contracts (interfaces), and integration guide
+
+### Data Model
+
+Create `data-model.md` with the following entities:
+
+#### Entity: StackTier
+
+Represents a platform stack complexity level (Dragon Ball Super metaphor).
+
+**Attributes**:
+- `ID` (string): Unique identifier (e.g., "super-saiyan")
+- `Name` (string): Display name (e.g., "Super Saiyan")
+- `Description` (string): Brief explanation of tier (1-2 sentences)
+- `Services` ([]string): List of included service names
+- `MinCPU` (int): Minimum CPU cores required
+- `MinRAM` (int): Minimum RAM in GB
+- `Enabled` (bool): Whether tier is available for selection
+- `Color` (lipgloss.Color): Visual theme color
+
+**Validation Rules**:
+- ID must be lowercase kebab-case
+- Name must be non-empty
+- Services list may be empty for disabled tiers
+- MinCPU must be > 0 for enabled tiers
+- MinRAM must be > 0 for enabled tiers
+- Color must be valid hex color code
+
+**Instances** (constants):
+1. **Super Saiyan** (Default/Enabled)
+   - ID: "super-saiyan"
+   - Services: Traefik, Kratos, Postgres, LiveKit
+   - MinCPU: 2, MinRAM: 4
+   - Color: #FFD700 (Gold)
+
+2. **Super Saiyan Blue** (Coming Soon)
+   - ID: "super-saiyan-blue"
+   - Services: TBD
+   - MinCPU: 4, MinRAM: 8
+   - Color: #00BFFF (Blue)
+   - Enabled: false
+
+3. **Ultra Instinct** (Coming Soon)
+   - ID: "ultra-instinct"
+   - Services: TBD
+   - MinCPU: 8, MinRAM: 16
+   - Color: #E6E6FA (Lavender)
+   - Enabled: false
+
+---
+
+#### Entity: WizardState
+
+Represents the current state of the wizard session (ephemeral, in-memory).
+
+**Attributes**:
+- `CurrentStep` (wizardStep): Current wizard phase (enum: StackSelection, PathSelection, Installation, Completion)
+- `SelectedTierIndex` (int): Index into tiers array (0-2)
+- `Tiers` ([]StackTier): Available tier options
+- `InstallPath` (string): User-entered installation directory
+- `ShowModal` (bool): Whether "Coming Soon" modal is visible
+- `ModalContent` (string): Dynamic modal message content
+- `TermWidth` (int): Current terminal width (columns)
+- `TermHeight` (int): Current terminal height (rows)
+- `InstallState` (InstallState): Current installation sub-state
+- `InstallProgress` (float64): Progress percentage (0.0-1.0)
+
+**State Transitions**:
+```
+StackSelection → PathSelection (when enabled tier selected)
+StackSelection → StackSelection (when disabled tier selected, modal shown)
+PathSelection → Installation (when path confirmed)
+Installation → Completion (when progress reaches 100%)
+Any State → Exit (when 'q' or Ctrl+C pressed)
+```
+
+**Lifecycle**: Created on wizard init, destroyed on exit. No persistence.
+
+---
+
+#### Entity: InstallState (Enum)
+
+Represents granular installation progress states.
+
+**Values**:
+- `StateValidating` (0): Checking prerequisites, validating path (0-20%)
+- `StateDownloading` (1): Fetching templates or images (20-40%)
+- `StateConfiguring` (2): Generating configuration files (40-60%)
+- `StateWriting` (3): Writing files to disk (60-80%)
+- `StateComplete` (4): Installation finished (80-100%)
+
+**State Messages**:
+- Validating: "Validating installation path..."
+- Downloading: "Downloading configuration templates..."
+- Configuring: "Generating docker-compose.yml..."
+- Writing: "Writing configuration files..."
+- Complete: "Setup complete!"
+
+---
+
+### API Contracts (Interfaces)
+
+Create `contracts/init-operation.go` with interface definitions:
+
+```go
+package contracts
+
+import "context"
+
+// InitOperation represents an initialization operation (file generation, network fetch, etc.)
+// Implementations: MockInitOperation (Phase 1), DockerComposeOperation (future), EnvFileOperation (future)
+type InitOperation interface {
+    // Execute runs the operation asynchronously with progress callbacks
+    // ctx: Cancellation context (Ctrl+C handling)
+    // onProgress: Callback invoked on state changes - func(state InstallState, progress float64)
+    // Returns: error if operation fails
+    Execute(ctx context.Context, onProgress func(InstallState, float64)) error
+
+    // Validate checks if operation prerequisites are met (path writable, disk space, etc.)
+    // Returns: error describing validation failure, nil if valid
+    Validate() error
+
+    // Description returns a human-readable operation summary
+    // Example: "Generate docker-compose.yml for Super Saiyan tier"
+    Description() string
+}
+
+// InstallState represents granular installation progress states
+type InstallState int
+
+const (
+    StateValidating InstallState = iota  // 0-20%
+    StateDownloading                      // 20-40%
+    StateConfiguring                      // 40-60%
+    StateWriting                          // 60-80%
+    StateComplete                         // 80-100%
+)
+
+// String returns human-readable state name
+func (s InstallState) String() string {
+    return [...]string{"Validating", "Downloading", "Configuring", "Writing", "Complete"}[s]
+}
+
+// Message returns user-facing progress message
+func (s InstallState) Message() string {
+    return [...]string{
+        "Validating installation path...",
+        "Downloading configuration templates...",
+        "Generating docker-compose.yml...",
+        "Writing configuration files...",
+        "Setup complete!",
+    }[s]
+}
+```
+
+**Contract Guarantees**:
+1. `Execute()` MUST call `onProgress()` at least once per state
+2. `Execute()` MUST respect `ctx.Done()` for cancellation
+3. `Validate()` MUST be idempotent (safe to call multiple times)
+4. Progress values MUST be monotonically increasing (0.0 → 1.0)
+5. `StateComplete` MUST always have progress = 1.0
+
+---
+
+### Integration Guide
+
+Create `quickstart.md` with:
+
+#### For Developers Implementing Wizard
+
+**1. Running the Wizard**
+```bash
+go run ./cmd/arc init
+# Or after build:
+./arc init
+```
+
+**2. Testing Wizard States**
+```bash
+# Run unit tests
+go test ./pkg/cli -run TestInitWizard -v
+
+# Test with race detector
+go test ./pkg/cli -race -run TestInitWizard
+
+# Coverage report
+go test ./pkg/cli -coverprofile=coverage.out -run TestInit
+go tool cover -html=coverage.out
+```
+
+**3. Manual Testing Scenarios**
+- Test on 80x24 terminal (minimum supported)
+- Test on 200x50 terminal (large screen)
+- Test terminal resize during wizard
+- Test color vs non-color terminals (`TERM=dumb ./arc init`)
+- Test rapid key presses (arrow spam)
+- Test Ctrl+C interruption at each state
+
+**4. Debugging Tips**
+```go
+// Add debug logging (remove before commit)
+import "github.com/charmbracelet/log"
+
+log.Debug("State transition", "from", oldStep, "to", newStep)
+log.Debug("Terminal size", "width", m.termWidth, "height", m.termHeight)
+```
+
+---
+
+#### For Future Implementers Adding Real I/O
+
+**1. Implementing InitOperation Interface**
+```go
+// Step 1: Create new operation type
+type DockerComposeOperation struct {
+    tier StackTier
+    path string
+}
+
+// Step 2: Implement interface methods
+func (d *DockerComposeOperation) Execute(ctx context.Context, onProgress func(InstallState, float64)) error {
+    // Implementation here
+}
+
+// Step 3: Replace MockInitOperation in wizard
+func createInitOperation(tier StackTier, path string) InitOperation {
+    return &DockerComposeOperation{tier: tier, path: path}
+    // Was: return &MockInitOperation{tier: tier, path: path}
+}
+```
+
+**2. Adding New Installation States**
+```go
+// Extend InstallState enum
+const (
+    StateValidating InstallState = iota
+    StateDownloading
+    StateConfiguring
+    StateWriting
+    StatePullingImages  // NEW
+    StateComplete
+)
+```
+
+**3. Plugging In Network Operations**
+```go
+type NetworkFetchOperation struct {
+    url string
+}
+
+func (n *NetworkFetchOperation) Execute(ctx context.Context, onProgress func(InstallState, float64)) error {
+    // HTTP fetch with context cancellation
+}
+```
+
+---
+
+### Agent Context Update
+
+Run `.specify/scripts/bash/update-agent-context.sh copilot` to add:
+- Charmbracelet Bubbles components (list, progress, textinput, viewport)
+- InitOperation interface pattern
+- Wizard state machine architecture
+- Theme integration approach
+
+This updates the AI agent's context for future assistance.
+
+## Code Quality & Testing Standards
+
+**Linting Requirements**:
+- All code MUST pass golangci-lint checks defined in `.golangci.yml` (48 linters enabled)
+- Run `make lint` before committing code
+- Use `//nolint` directives ONLY with required explanation comments
+- See `.specify/docs/decisions/linting-standards.md` for detailed guidelines
+
+**Test Coverage Targets** (from spec requirements):
+- **Core wizard state machine logic**: 75%+ coverage (T070-T074 tasks)
+- **Card selection and navigation logic**: 80%+ coverage (T071 task)
+- **Footer responsiveness calculations**: 80%+ coverage (T052 task)
+- **UI rendering functions (View methods)**: 40%+ coverage (T034, T043 tasks)
+
+**Testing Approach**:
+- **Table-driven tests** for state transitions (given/when/then scenarios from spec)
+- **Mock Bubble Tea messages** for Update() method testing
+- **Snapshot testing** (optional) for View() output validation
+- **Terminal size matrix**: Test 60, 70, 80, 100, 120 column widths
+- **Edge cases**: rapid key presses, unsupported keys, terminal too small, color fallback
+- Reference existing `pkg/cli/info_test.go` for Bubble Tea testing patterns
+
+**Pre-Commit Quality Gates**:
+- [ ] `make quality` (fmt + vet + lint) passes
+- [ ] `make test` (with race detector) passes
+- [ ] Coverage targets met: State machine 75%+, Navigation 80%+, Footer 80%+, UI 40%+
+- [ ] No unjustified `//nolint` directives
+- [ ] Manual testing on 80x24 and 120x40 terminals
+- [ ] Manual testing on different terminals (Terminal.app, iTerm2, VSCode)
+
+**References**:
+- Testing guidelines: `docs/TESTING.md`
+- Linting standards: `.specify/docs/decisions/linting-standards.md`
+- Task breakdown with test requirements: `tasks.md` (Phase 7)
+
+## Complexity Tracking
+
+> **Fill ONLY if Constitution Check has violations that must be justified**
+
+**Status**: No violations - all Constitution principles compliant or explicitly deferred per spec scope
+
+| Violation | Why Needed | Simpler Alternative Rejected Because |

+# Quickstart Guide: Arc Init Wizard
+
+**Phase**: 1 (Design & Contracts)
+**Date**: 2025-12-25
+**Audience**: Developers implementing and extending the wizard
+
+## Overview
+
+This guide helps you get started with developing, testing, and extending the Arc Init Wizard. It covers local development, testing strategies, and integration patterns.
+
+---
+
+## For Developers: Implementing the Wizard
+
+### Prerequisites
+
+- Go 1.24.0 or later
+- Terminal emulator supporting ANSI escape codes
+- `make` utility (optional, for convenience commands)
+
+### Quick Start
+
+```bash
+# 1. Clone and navigate to repository
+cd /Users/dgtalbug/Workspace/arc/cli
+
+# 2. Checkout feature branch
+git checkout 007-init-wizard
+
+# 3. Install dependencies (if not already present)
+go mod tidy
+
+# 4. Run the wizard in development mode
+go run ./cmd/arc init
+
+# Or build and run:
+make build
+./arc init
+```
+
+###
+
+ Running the Wizard
+
+**Interactive Mode** (default):
+```bash
+./arc init
+```
+
+**Future: Non-Interactive Mode** (when flags implemented):
+```bash
+# Future feature - not in Phase 1
+./arc init --tier=super-saiyan --path=./my-project --yes
+```
+
+### Development Workflow
+
+1. **Make changes** to `pkg/cli/init.go`
+2. **Run linter**: `make lint` (or `golangci-lint run ./pkg/cli/`)
+3. **Run tests**: `go test ./pkg/cli -run TestInit -v`
+4. **Manual test**: `go run ./cmd/arc init`
+5. **Check coverage**: `go test ./pkg/cli -coverprofile=coverage.out && go tool cover -html=coverage.out`
+
+---
+
+## Testing the Wizard
+
+### Unit Tests
+
+**Run all init wizard tests:**
+```bash
+go test ./pkg/cli -run TestInit -v
+```
+
+**Run specific test:**
+```bash
+go test ./pkg/cli -run TestInitWizard/state_transitions -v
+```
+
+**With race detector:**
+```bash
+go test ./pkg/cli -race -run TestInit
+```
+
+**Generate coverage report:**
+```bash
+go test ./pkg/cli -coverprofile=coverage.out -run TestInit
+go tool cover -html=coverage.out
+```
+
+**Coverage targets** (from spec):
+- State machine logic: 75%+
+- Navigation logic: 80%+
+- Footer responsiveness: 80%+
+- UI rendering: 40%+
+
+### Manual Testing Scenarios
+
+#### Terminal Size Testing
+
+```bash
+# Test minimum size (80x24)
+resize -s 24 80
+./arc init
+
+# Test common size (120x40)
+resize -s 40 120
+./arc init
+
+# Test large size (200x50)
+resize -s 50 200
+./arc init
+
+# Test too small (should show warning)
+resize -s 15 60
+./arc init
+```
+
+#### Theme Testing
+
+```bash
+# Test with default theme
+./arc init
+
+# Test with different theme (after changing preference)
+# Edit ~/.config/arc/preferences.yaml:
+#   theme: "dracula"
+./arc init
+
+# Test with no color support
+TERM=dumb ./arc init
+NO_COLOR=1 ./arc init
+```
+
+#### Keyboard Navigation Testing
+
+1. **Arrow Keys**: Press left/right to navigate between tiers
+2. **Enter Key**: Select tier, confirm path, dismiss modal
+3. **Escape Key**: Dismiss "Coming Soon" modal
+4. **'q' Key**: Quit wizard from any state
+5. **Ctrl+C**: Interrupt wizard (should exit cleanly)
+6. **Rapid Keys**: Spam arrow keys to test debouncing
+
+#### Edge Cases
+
+- **Interrupt during installation**: Press Ctrl+C while spinner is running
+- **Resize during wizard**: Change terminal size while wizard is active
+- **Invalid keys**: Press spacebar, tab, function keys (should be ignored)
+- **Disabled tier selection**: Press Enter on Blue or Ultra Instinct tiers (should show modal)
+
+### Testing with Different Terminals
+
+```bash
+# macOS Terminal.app
+open -a Terminal
+./arc init
+
+# iTerm2
+open -a iTerm
+./arc init
+
+# VSCode integrated terminal
+code .
+# In terminal panel: ./arc init
+
+# tmux/screen (test color detection)
+tmux
+./arc init
+
+# SSH session (test over network)
+ssh user@host
+./arc init
+```
+

+
+## Debugging Tips
+
+### Enable Debug Logging
+
+```go
+// Temporary debug code (remove before commit)
+import "github.com/charmbracelet/log"
+
+log.SetLevel(log.DebugLevel)
+
+// In Update() method:
+log.Debug("State transition", "from", m.currentStep, "to", newStep)
+log.Debug("Key pressed", "key", key.String())
+log.Debug("Terminal size", "width", m.termWidth, "height", m.termHeight)
+```
+
+### Print Model State
+
+```go
+// In View() method (temporary debug):
+return fmt.Sprintf("DEBUG: step=%v, tierIndex=%d, path=%s, modal=%v\n%s",
+    m.currentStep, m.selectedTierIndex, m.installPath, m.showModal, actualView)
+```
+
+### Trace Bubble Tea Messages
+
+```go
+// In Update() method:
+func (m *initModel) Update(msg tea.Msg) (tea.Model, tea.Cmd) {
+    fmt.Fprintf(os.Stderr, "MSG: %T - %+v\n", msg, msg) // Trace all messages
+    // ... rest of Update logic
+}
+```
+
+### Use Bubble Tea's Built-in Debugging
+
+```bash
+# Set environment variable to log Bubble Tea messages
+DEBUG=1 go run ./cmd/arc init
+```
+

+
+## For Future Implementers: Adding Real I/O
+
+This section guides future developers adding actual file generation and network operations.
+
+### Step 1: Implement InitOperation Interface
+
+Create a new operation type:
+
+```go
+// In pkg/cli/init.go or future pkg/init/operations/docker_compose.go
+
+type DockerComposeOperation struct {
+    tier     StackTier
+    path     string
+    templates embed.FS // Embed templates with go:embed
+}
+
+// Implement Execute()
+func (d *DockerComposeOperation) Execute(ctx context.Context, onProgress func(InstallState, float64)) error {
+    // See contracts/init-operation.go for full example
+
+    // Validating (0-20%)
+    onProgress(StateValidating, 0.2)
+    if err := d.validatePath(); err != nil {
+        return err
+    }
+
+    // Downloading (20-40%)
+    onProgress(StateDownloading, 0.4)
+    // Fetch templates if not embedded
+
+    // Configuring (40-60%)
+    onProgress(StateConfiguring, 0.6)
+    config, err := d.renderTemplate()
+    if err != nil {
+        return err
+    }
+
+    // Writing (60-80%)
+    onProgress(StateWriting, 0.8)
+    if err := d.writeFiles(config); err != nil {
+        return err
+    }
+
+    // Complete (80-100%)
+    onProgress(StateComplete, 1.0)
+    return nil
+}
+
+// Implement Validate()
+func (d *DockerComposeOperation) Validate() error {
+    // Check path exists, is writable, has space, etc.
+    return nil
+}
+
+// Implement Description()
+func (d *DockerComposeOperation) Description() string {
+    return fmt.Sprintf("Generate docker-compose.yml for %s tier in %s", d.tier.Name, d.path)
+}
+```
+
+### Step 2: Replace Mock in Wizard
+
+Update the operation factory:
+
+```go
+// OLD (Phase 1):
+func createInitOperation(tier StackTier, path string) InitOperation {
+    return &MockInitOperation{tier: tier, path: path}
+}
+
+// NEW (Future Phase):
+func createInitOperation(tier StackTier, path string) InitOperation {
+    return &DockerComposeOperation{tier: tier, path: path}
+}
+```
+
+**That's it!** The wizard code doesn't change - only the operation implementation.
+
+### Step 3: Add New Installation States (Optional)
+
+If your operation needs more granular progress:
+
+```go
+// In contracts/init-operation.go, extend InstallState:
+
+const (
+    StateValidating InstallState = iota
+    StateDownloading
+    StateConfiguring
+    StatePullingImages  // NEW: Download Docker images
+    StateWriting
+    StateComplete
+)
+
+// Update String() and Message() methods accordingly
+```
+
+Update wizard to handle new states:
+
+```go
+// In wizard Update() method:
+case installProgressMsg:
+    m.installState = msg.state
+    m.installProgress = msg.progress
+
+    // Map state to UI message
+    switch msg.state {
+    case StatePullingImages:
+        m.installMessage = "Pulling Docker images (this may take a few minutes)..."
+    // ... other states
+    }
+```
+
+---
+
+## Integration Patterns
+
+### Embedding Templates
+
+Use Go's `embed` package for bundled templates:
+
+```go
+//go:embed templates/*.yaml
+var templateFS embed.FS
+
+func (d *DockerComposeOperation) loadTemplate(name string) ([]byte, error) {
+    return templateFS.ReadFile(fmt.Sprintf("templates/%s.yaml", name))
+}
+```
+
+### Network Operations with Context
+
+Respect context cancellation in network calls:
+
+```go
+func (n *NetworkFetchOperation) downloadTemplate(ctx context.Context, url string) ([]byte, error) {
+    req, err := http.NewRequestWithContext(ctx, "GET", url, nil)
+    if err != nil {
+        return nil, err
+    }
+
+    resp, err := http.DefaultClient.Do(req)
+    if err != nil {
+        return nil, err
+    }
+    defer resp.Body.Close()
+
+    // Check ctx.Done() during read
+    return io.ReadAll(resp.Body)
+}
+```
+
+### Progress Granularity
+
+For long-running operations, call `onProgress()` more frequently:
+
+```go
+func (d *DockerComposeOperation) Execute(ctx context.Context, onProgress func(InstallState, float64)) error {
+    totalSteps := 10
+    for i := 0; i < totalSteps; i++ {
+        select {
+        case <-ctx.Done():
+            return ctx.Err()
+        default:
+            // Do work
+            time.Sleep(100 * time.Millisecond)
+
+            // Calculate progress within current state
+            stateProgress := float64(i) / float64(totalSteps)
+            overallProgress := 0.4 + (stateProgress * 0.2) // 40-60% range
+            onProgress(StateConfiguring, overallProgress)
+        }
+    }
+    return nil
+}
+```
+
+---
+
+## Common Issues & Solutions
+
+### Issue: Wizard doesn't quit on Ctrl+C
+
+**Solution**: Ensure `tea.WithAltScreen()` is set and signal handling is enabled:
+
+```go
+p := tea.NewProgram(initialInitModel(), tea.WithAltScreen())
+if _, err := p.Run(); err != nil {
+    fmt.Fprintf(os.Stderr, "Error: %v\n", err)
+    os.Exit(1)
+}
+```
+
+### Issue: Colors don't show in some terminals
+
+**Solution**: Implement color fallback:
+
+```go
+if !lipgloss.HasDarkBackground() {
+    // Adjust colors for light terminals
+}
+
+if os.Getenv("NO_COLOR") != "" || os.Getenv("TERM") == "dumb" {
+    // Use plain text rendering
+}
+```
+
+### Issue: Terminal size detection fails
+
+**Solution**: Graceful fallback to default size:
+
+```go
+width, height, err := term.GetSize(int(os.Stdout.Fd()))
+if err != nil {
+    width, height = 120, 40 // Fallback default
+}
+```
+
+### Issue: Tests fail in CI (no TTY)
+
+**Solution**: Mock terminal size in tests:
+
+```go
+func TestInitWizard(t *testing.T) {
+    m := initialInitModel()
+    m.termWidth = 120  // Override in test
+    m.termHeight = 40
+
+    // Run test without actual terminal
+}
+```

+# Research: Arc Init Wizard
+
+**Phase**: 0 (Outline & Research)
+**Date**: 2025-12-25
+**Plan**: [plan.md](./plan.md)
+
+## Overview
+
+This document captures research findings and technical decisions for implementing the Arc Init Wizard using modern Charmbracelet components and I/O abstraction patterns.
+
+---
+
+## Decision 1: Charmbracelet Components Selection
+
+### Context
+
+The wizard requires rich terminal UI with tier selection, text input, progress tracking, and modal overlays. We evaluated manual rendering vs leveraging Charmbracelet's `bubbles` component library.
+
+### Options Considered
+
+| Component | Purpose | Pros | Cons |
+|-----------|---------|------|------|
+| Manual lipgloss rendering | Tier card layout | Full control, no dependencies | Complex navigation logic, accessibility gaps, maintenance burden |
+| `bubbles/list` | Tier selection | Built-in navigation, keyboard handling, viewport scrolling | Learning curve, constrained styling |
+| `bubbles/progress` | Install progress | Smooth animations, percentage display | Fixed width handling |
+| `bubbles/textinput` | Path entry | Cursor management, UTF-8 support | Limited to single-line input |
+| `bubbles/viewport` | Modal scrolling | Content overflow handling | Overkill for small modals |
+
+### Decision
+
+**Adopt `bubbles` components** for all interactive elements:
+
+1. **`bubbles/list`** for tier selection
+   - Delegates keyboard navigation to proven component
+   - Custom item delegate for Dragon Ball themed rendering
+   - Handles circular navigation (wrap-around) automatically
+
+2. **`bubbles/progress`** for installation progress bar
+   - Maps 5 installation states to 0-100% progress
+   - Built-in gradient rendering (matches Arc CLI theme)
+   - Smooth animation transitions
+
+3. **`bubbles/textinput`** for path entry
+   - Eliminates manual cursor position tracking
+   - Handles UTF-8 correctly (important for international paths)
+   - Built-in validation callback support
+
+4. **`bubbles/viewport`** for "Coming Soon" modal
+   - Future-proof for longer tier descriptions
+   - Keyboard scrolling (↑/↓) if content overflows
+
+### Rationale
+
+- **Reduces development time**: ~2-3 days saved vs manual implementation
+- **Better accessibility**: Components follow terminal UI best practices
+- **Maintainability**: Upstream bug fixes benefit our wizard
+- **Consistency**: Matches patterns in other CLI tools (gh, kubectl)
+
+### Implementation Notes
+
+```go
+// Example: Tier selection with bubbles/list
+type tierItem struct {
+    tier StackTier
+}
+
+func (t tierItem) FilterValue() string { return t.tier.Name }
+
+type tierDelegate struct {
+    activeTheme themes.Theme
+}
+
+func (d tierDelegate) Render(w io.Writer, m list.Model, index int, listItem list.Item) {
+    // Custom rendering with Dragon Ball colors
+    tier := listItem.(tierItem).tier
+    style := lipgloss.NewStyle().Foreground(tier.Color)
+    // ...
+}
+```
+
+**Reference**: [Charm Bubbles Documentation](https://github.com/charmbracelet/bubbles)
+
+---
+
+## Decision 2: Theme Integration Strategy
+
+### Context
+
+The wizard uses Dragon Ball Super metaphor with specific tier colors (Gold, Blue, Lavender). However, Arc CLI supports user-configurable themes. We need to balance brand identity with user preferences.
+
+### Options Considered
+
+| Option | Approach | Pros | Cons |
+|--------|----------|------|------|
+| A | Fixed Dragon Ball colors everywhere | Consistent branding, recognizable tiers | Ignores user theme, poor accessibility |
+| B | Hybrid: Tier colors fixed, UI chrome themed | Balances branding + preferences | Slight complexity in style management |
+| C | Full theme override of tier colors | Maximum consistency | Breaks Dragon Ball metaphor |
+
+### Decision
+
+**Option B: Hybrid approach**
+
+- **Tier card colors**: Always use Dragon Ball colors (#FFD700, #00BFFF, #E6E6FA)
+- **UI chrome**: Use active theme for borders, footer, modal, background
+- **Disabled tiers**: Grey (#7D7D7D) regardless of theme
+
+### Rationale
+
+- Dragon Ball colors are **semantic** (part of the feature metaphor)
+- UI chrome colors are **aesthetic** (should respect user preferences)
+- Similar to syntax highlighting (keywords have semantic colors, backgrounds are themed)
+
+### Implementation
+
+```go
+// Load active theme once during init
+appState, _ := preferences.Load()
+themeName := appState.GetTheme()
+theme := themes.Available()[themeName]
+
+// Apply to UI chrome
+modalBorderStyle := lipgloss.NewStyle().
+    BorderStyle(lipgloss.RoundedBorder()).
+    BorderForeground(theme.BorderColor)  // From theme
+
+footerTextStyle := lipgloss.NewStyle().
+    Foreground(theme.SecondaryTextColor) // From theme
+
+// Keep tier colors fixed
+superSaiyanCard := lipgloss.NewStyle().
+    Foreground(lipgloss.Color("#FFD700")) // Always gold (override theme)
+```
+
+### Theme Color Mapping
+
+| UI Element | Color Source | Example Value |
+|-----------|--------------|---------------|
+| Tier card (Super Saiyan) | Fixed | #FFD700 (Gold) |
+| Tier card (Blue) | Fixed | #00BFFF (Blue) |
+| Tier card (Ultra Instinct) | Fixed | #E6E6FA (Lavender) |
+| Disabled tier | Fixed grey | #7D7D7D |
+| Modal border | Active theme | theme.BorderColor |
+| Footer text | Active theme | theme.SecondaryTextColor |
+| Modal background | Active theme | theme.BackgroundColor |
+
+**Fallback**: If theme loading fails, use legacy default theme (already implemented in `pkg/ui/themes`).
+
+---
+
+## Decision 3: I/O Abstraction Interface Design
+
+### Context
+
+This phase implements UI-only wizard (mock I/O operations). Future phase will add real file generation and network fetching. We need an interface that supports both without refactoring wizard logic.
+
+### Requirements
+
+1. Support async operations with progress callbacks
+2. Enable context cancellation (Ctrl+C handling)
+3. Allow multiple operations (file write, network fetch, Docker config)
+4. Provide granular progress states (5 steps: Validating → Downloading → Configuring → Writing → Complete)
+
+### Design: InitOperation Interface
+
+```go
+// InitOperation represents an initialization operation (file I/O, network I/O, etc.)
+type InitOperation interface {
+    // Execute runs the operation asynchronously
+    // ctx: Context for cancellation (e.g., Ctrl+C)
+    // onProgress: Callback for progress updates - func(state InstallState, progress float64)
+    //            state: Current operation phase (Validating, Downloading, etc.)
+    //            progress: Percentage complete (0.0 to 1.0)
+    // Returns: error if operation fails, nil on success
+    Execute(ctx context.Context, onProgress func(InstallState, float64)) error
+
+    // Validate checks prerequisites before execution
+    // Examples: Path is writable, disk space available, network reachable
+    // Returns: error describing validation failure, nil if valid
+    Validate() error
+
+    // Description returns human-readable operation summary
+    // Used in logs and error messages
+    Description() string
+}
+```
+
+### Progress State Enum
+
+```go
+type InstallState int
+
+const (
+    StateValidating  InstallState = iota  // 0-20%: Check prerequisites
+    StateDownloading                      // 20-40%: Fetch templates/images
+    StateConfiguring                      // 40-60%: Generate configs
+    StateWriting                          // 60-80%: Write to disk
+    StateComplete                         // 80-100%: Finished
+)
+
+// Message returns user-facing progress text
+func (s InstallState) Message() string {
+    return [...]string{
+        "Validating installation path...",
+        "Downloading configuration templates...",
+        "Generating docker-compose.yml...",
+        "Writing configuration files...",
+        "Setup complete!",
+    }[s]
+}
+```
+
+### Mock Implementation (This Phase)
+
+```go
+// MockInitOperation simulates I/O with time delays
+type MockInitOperation struct {
+    tier StackTier
+    path string
+}
+
+func (m *MockInitOperation) Execute(ctx context.Context, onProgress func(InstallState, float64)) error {
+    states := []InstallState{
+        StateValidating,
+        StateDownloading,
+        StateConfiguring,
+        StateWriting,
+        StateComplete,
+    }
+
+    for i, state := range states {
+        select {
+        case <-ctx.Done():
+            return ctx.Err() // Respect cancellation
+        case <-time.After(500 * time.Millisecond):
+            progress := float64(i+1) / float64(len(states))
+            onProgress(state, progress)
+        }
+    }
+    return nil
+}
+
+func (m *MockInitOperation) Validate() error {
+    // No validation in mock
+    return nil
+}
+
+func (m *MockInitOperation) Description() string {
+    return fmt.Sprintf("Mock installation of %s tier to %s", m.tier.Name, m.path)
+}
+```
+
+### Real Implementation Example (Future Phase)
+
+```go
+// DockerComposeOperation generates docker-compose.yml from templates
+type DockerComposeOperation struct {
+    tier     StackTier
+    path     string
+    tmpl     *template.Template
+    httpClient *http.Client
+}
+
+func (d *DockerComposeOperation) Execute(ctx context.Context, onProgress func(InstallState, float64)) error {
+    // Validating
+    onProgress(StateValidating, 0.2)
+    if err := d.checkDiskSpace(); err != nil {
+        return fmt.Errorf("validation failed: %w", err)
+    }
+
+    // Downloading
+    onProgress(StateDownloading, 0.4)
+    template, err := d.fetchTemplate(ctx)
+    if err != nil {
+        return fmt.Errorf("download failed: %w", err)
+    }
+
+    // Configuring
+    onProgress(StateConfiguring, 0.6)
+    config, err := d.generateConfig(template)
+    if err != nil {
+        return fmt.Errorf("config generation failed: %w", err)
+    }
+
+    // Writing
+    onProgress(StateWriting, 0.8)
+    if err := d.writeFiles(config); err != nil {
+        return fmt.Errorf("write failed: %w", err)
+    }
+
+    // Complete
+    onProgress(StateComplete, 1.0)
+    return nil
+}
+```
+
+### Wizard Integration
+
+```go
+// In wizard Update() method
+case tea.KeyMsg:
+    if key.String() == "enter" && m.currentStep == PathSelection {
+        m.currentStep = Installation
+
+        operation := createInitOperation(m.tiers[m.selectedTierIndex], m.installPath)
+
+        return m, func() tea.Msg {
+            ctx, cancel := context.WithTimeout(context.Background(), 30*time.Second)
+            defer cancel()
+
+            err := operation.Execute(ctx, func(state InstallState, progress float64) {
+                // Send progress updates as Bubble Tea messages
+                // Will update m.installState and m.installProgress
+            })
+
+            if err != nil {
+                return installErrorMsg{err}
+            }
+            return installCompleteMsg{}
+        }
+    }
+```
+
+### Rationale
+
+- **Callback pattern**: Allows real-time UI updates without polling
+- **Context cancellation**: Clean shutdown on Ctrl+C
+- **Progress percentage**: Maps directly to `bubbles/progress` component
+- **State enum**: Provides semantic progress messages for UI
+- **Interface abstraction**: Swap mock → real without changing wizard code
+
+### Future Extensions
+
+When adding new operation types (future phases):
+
+1. **Implement InitOperation interface**
+2. **Add new InstallState values** (if needed)
+3. **Update factory function** (`createInitOperation()`)
+4. **No wizard logic changes required**
+
+**Plugin Pattern Evaluation**: If we have 3+ operation types, consider extracting to separate package (`pkg/init/operations/`). Currently 2 implementations (mock, docker-compose) - keep inline per user's pragmatic plugin preference.
+

+
+## Decision 4: Terminal Size Responsiveness
+
+### Context
+
+Wizard must work on various terminal sizes (80x24 minimum, 200x50 large). Layout should adapt gracefully without breaking.
+
+### Terminal Size Matrix
+
+| Width | Height | Layout Strategy |
+|-------|--------|-----------------|
+| < 80  | Any    | Show warning: "Terminal too small. Please resize to at least 80x20." |
+| 80-120 | < 20  | Show warning |
+| 80-120 | 20-30 | Compact mode: Vertical card stack, minimal padding, truncated footer |
+| 80-120 | > 30  | Compact mode: Vertical card stack, normal padding, full footer |

+| > 120 | 20-30 | Full mode: Horizontal cards (3 columns), minimal padding |
+| > 120 | > 30  | Full mode: Horizontal cards, generous padding |
+
+### Footer Responsiveness
+
+| Terminal Width | Footer Rendering |
+|---------------|------------------|
+| < 80 cols     | "[←/→] • [↵] • [q]" \| "v1.0.0" (minimal) |
+| 80-100 cols   | "[←/→] Select • [↵] Confirm • [q] Quit" \| "Arc CLI v1.0.0" (compact) |
+| > 100 cols    | "[←/→] Select Tier • [Enter] Confirm • [q] Quit" \| "A.R.C. CLI v1.0.0" (full) |
+
+### Implementation
+
+```go
+func (m *initModel) View() string {
+    // Detect terminal size
+    width, height, _ := term.GetSize(int(os.Stdout.Fd()))
+    m.termWidth = width
+    m.termHeight = height
+
+    // Enforce minimum

+        return m.renderTerminalTooSmall()
+    }
+
+    // Adaptive layout
+    if width > 120 {
+        return m.renderFullLayout()
+    }
+    return m.renderCompactLayout()
+}

+```
+
+### Testing Matrix
+
+Manual testing required on:
+- **80x24**: Minimum supported (compact mode)
+- **120x40**: Common developer terminal
+- **200x50**: Large monitor (full mode)
+- **Resize test**: Start at 120x40, resize to 70x20 while wizard running
+
+### Rationale
+
+- **80x20 minimum**: Industry standard (matches VT100, SSH defaults)
+- **Graceful degradation**: Show warning instead of rendering broken UI
+- **Adaptive layout**: Maximize information density without truncation
+- **Footer truncation**: Preserve version info (critical), abbreviate controls (contextual)
+
+---
+
+## Summary of Research Findings
+
+| Question | Decision | Rationale |
+|----------|----------|-----------|
+| Which UI components? | `bubbles/list`, `progress`, `textinput`, `viewport` | Proven patterns, accessibility, maintainability |
+| How to handle themes? | Hybrid: Fixed tier colors, themed UI chrome | Balances branding + user preferences |
+| How to abstract I/O? | `InitOperation` interface with callback pattern | Swap mock → real without refactoring wizard |
+| How to handle terminal size? | Adaptive layout with 80x20 minimum | Graceful degradation, maximize usability |
+
+**All NEEDS CLARIFICATION items resolved** ✅
+
+**Ready to proceed to**: Phase 1 (Design & Contracts)

+# Feature Specification: Arc Init Wizard
+
+**Feature Branch**: `007-init-wizard`
+**Created**: 2025-12-25
+**Status**: Draft
+**Input**: User description: "Interactive wizard that guides users through selecting a platform stack (Dragon Ball Super tiering) and scaffolding directory structure using Bubble Tea TUI framework"
+
+## Feature Overview
+
+The `arc init` command provides an interactive terminal-based wizard that guides users through platform stack selection and project initialization. Using the "Dragon Ball Super" tiering metaphor, the wizard presents stack complexity levels as visual cards, collects installation preferences, and simulates the setup process with rich terminal UI feedback.
+
+This feature focuses purely on the UI/UX flow and visual presentation. Actual file generation and Docker configuration are deferred to a future phase.
+
+## User Scenarios & Testing *(mandatory)*
+
+### User Story 1 - Select Default Stack and Complete Wizard (Priority: P1)
+
+A developer new to A.R.C. wants to quickly scaffold a standard development environment with recommended services (Traefik, Kratos, Postgres, LiveKit) using sensible defaults.
+
+**Why this priority**: This is the primary happy path representing 80%+ of expected usage. Users need immediate value with minimal friction.
+
+**Independent Test**: Can be fully tested by running `arc init`, selecting the Super Saiyan tier, accepting the default installation path, and verifying the success screen displays. Delivers a complete wizard experience from start to finish.
+
+**Acceptance Scenarios**:
+
+1. **Given** the user runs `arc init` in an empty directory, **When** the wizard loads, **Then** the screen displays the ASCII banner header, three tier cards (Super Saiyan, Super Saiyan Blue, Ultra Instinct), and footer with controls
+2. **Given** the stack selection screen is displayed, **When** the user presses Enter on the Super Saiyan (default) card, **Then** the wizard transitions to the path selection screen
+3. **Given** the path selection screen is displayed with default value "./", **When** the user presses Enter without changing the path, **Then** the wizard transitions to the installation screen with a spinner
+4. **Given** the installation spinner is running, **When** the simulation completes (2-3 seconds), **Then** the wizard displays the success screen with "Setup Complete!" message and next steps
+
+---
+
+### User Story 2 - Explore Disabled Tiers (Priority: P2)
+
+A developer curious about future platform capabilities wants to explore all available tiers, including those not yet implemented, to understand the roadmap.
+
+**Why this priority**: Builds anticipation for future features and provides transparency about platform growth. Essential for user education and feature discovery.
+
+**Independent Test**: Can be fully tested by navigating between all three tier cards using arrow keys and attempting to select a disabled tier, verifying the "Coming Soon" modal appears and returns user to selection screen.
+
+**Acceptance Scenarios**:
+
+1. **Given** the stack selection screen is displayed, **When** the user presses the right arrow key, **Then** the selection moves to the Super Saiyan Blue card and it displays with a visual highlight
+2. **Given** the Super Saiyan Blue card is selected, **When** the user presses Enter, **Then** a modal appears with "Coming Soon" message explaining the tier is under development
+3. **Given** the "Coming Soon" modal is displayed, **When** the user presses Escape or Enter, **Then** the modal closes and the user returns to the stack selection screen
+4. **Given** any tier card is selected, **When** the user presses left/right arrow keys, **Then** the selection wraps around (Ultra Instinct → Super Saiyan → Blue → Ultra Instinct)
+
+---
+
+### User Story 3 - Navigate with Keyboard Controls (Priority: P2)
+
+A keyboard-focused developer wants to navigate the entire wizard using only keyboard shortcuts without touching the mouse.
+
+**Why this priority**: Terminal users expect keyboard-first navigation. Critical for accessibility and power user workflows.
+
+**Independent Test**: Can be fully tested by completing the entire wizard flow using only keyboard (arrows, Enter, q) without any mouse interaction.
+
+**Acceptance Scenarios**:
+
+1. **Given** any screen in the wizard is displayed, **When** the user presses 'q', **Then** the wizard exits immediately and returns to the shell prompt
+2. **Given** the stack selection screen is displayed, **When** the user presses Ctrl+C, **Then** the wizard exits immediately
+3. **Given** the path selection screen is displayed, **When** the user types a custom path like "./my-project", **Then** the text input updates in real-time and displays the typed path
+4. **Given** the path selection screen is displayed with modified text, **When** the user presses Backspace, **Then** characters are deleted from the end of the input
+
+---
+
+### User Story 4 - Handle Custom Installation Path (Priority: P3)
+
+A developer working on multiple projects wants to initialize A.R.C. in a specific subdirectory instead of the current directory.
+
+**Why this priority**: Common workflow pattern but not critical for initial adoption. Default path covers majority use cases.
+
+**Independent Test**: Can be fully tested by entering a custom path on the path selection screen and verifying the success message reflects the chosen location.
+
+**Acceptance Scenarios**:
+
+1. **Given** the path selection screen is displayed, **When** the user clears the default and types "./projects/arc-dev", **Then** the input field updates to show the custom path
+2. **Given** a custom path is entered, **When** the user presses Enter, **Then** the wizard proceeds to installation screen (path validation deferred to implementation phase)
+3. **Given** the success screen is displayed after using a custom path, **When** the screen renders, **Then** the message includes the custom path in the completion details
+
+---
+
+### Edge Cases
+
+- **What happens when terminal width is less than 80 columns?** Footer controls truncate gracefully (e.g., "[←/→] Select • ..." while maintaining version display on the right)
+- **What happens when terminal height is very small (< 20 lines)?** System displays warning message: "Terminal too small. Please resize to at least 80x20."
+- **What happens when a user rapidly presses arrow keys?** Selection updates smoothly without lag or skipped cards, using proper debouncing
+- **What happens when the user presses Enter on the "Coming Soon" modal?** Modal closes immediately and focus returns to the previously selected tier card
+- **What happens if no terminal color support is detected?** Wizard falls back to monochrome ASCII art with bold/underline for emphasis (no colors)
+- **What happens when the user presses an unsupported key (e.g., spacebar)?** Key press is ignored, no visual change or error message
+- **What happens if the installation spinner is interrupted?** This phase only simulates installation, so interruption (Ctrl+C) exits cleanly without side effects
+

+  - `Enabled`: Whether the tier is available for selection (bool)
+  - `Color`: Visual theme color for the tier (lipgloss.Color)
+
+- **WizardState**: Represents the current state of the wizard flow:
+  - Current step (StackSelection, PathSelection, Installation, Completion)
+  - Selected tier (StackTier reference)

+7. Path validation (checking permissions, directory existence) is deferred to the implementation phase
+8. The wizard operates in a single-user, local environment (no concurrent access concerns)
+
+### Code Quality & Testing Requirements
+
+**Test Coverage Expectations**:
+- Core wizard state machine logic: 75%+ coverage
+- UI rendering functions (View methods): 40%+ coverage
+- Card selection and navigation logic: 80%+ coverage
