# Specification Quality Checklist: Reference Board Viewer

**Purpose**: Validate specification completeness and quality before proceeding to planning  
**Created**: 2025-11-02  
**Feature**: [spec.md](../spec.md)  

## Content Quality

- [x] No implementation details (languages, frameworks, APIs)
- [x] Focused on user value and business needs
- [x] Written for non-technical stakeholders
- [x] All mandatory sections completed

**Notes:** Spec successfully avoids implementation details, focuses on WHAT users need and WHY. All requirements written in business terms.

## Requirement Completeness

- [x] No [NEEDS CLARIFICATION] markers remain
- [x] Requirements are testable and unambiguous
- [x] Success criteria are measurable
- [x] Success criteria are technology-agnostic (no implementation details)
- [x] All acceptance scenarios are defined
- [x] Edge cases are identified
- [x] Scope is clearly bounded
- [x] Dependencies and assumptions identified

**Notes:** 
- **All clarifications resolved:**
  1. FR3: Configurable share permissions (View-only or View+Comment) - owner decides per link
  2. FR16: Hybrid connection detection (automatic with manual override)
  3. FR13: User-configurable navigation order (Chronological, Spatial, Alphabetical, Random)
- All requirements have clear acceptance criteria
- Success criteria are measurable and technology-agnostic
- User scenarios cover primary flows comprehensively
- Scope clearly defined with 18 functional requirements

## Feature Readiness

- [x] All functional requirements have clear acceptance criteria
- [x] User scenarios cover primary flows
- [x] Feature meets measurable outcomes defined in Success Criteria
- [x] No implementation details leak into specification

**Notes:** 18 functional requirements with detailed acceptance criteria. 5 user scenarios covering critical paths.

## Clarification Resolutions

All clarification questions have been answered:

### Question 1: Viewer Annotation Capability ✅ RESOLVED

**User's Answer:** C - Configurable per share link (owner decides)

**Implementation Details Added to Spec:**
- Share links have two permission levels: View-only or View+Comment
- Owner chooses permission level when creating share link
- Owner can change permission level of existing links
- View+Comment allows annotations but not image/layout modifications
- Comments from viewers are visually distinct from owner content

### Question 2: Connection Speed Detection Method ✅ RESOLVED

**User's Answer:** C - Hybrid: Auto-detect with manual override option

**Implementation Details Added to Spec:**
- Automatic detection using browser Network Information API and speed test
- Three quality tiers: Low (<1 Mbps), Medium (1-5 Mbps), High (>5 Mbps)
- Manual override available: Auto/Low/Medium/High setting
- Quality setting selector easily accessible in UI
- Periodic re-evaluation (every 5 minutes) in Auto mode
- Setting persists across sessions

### Question 3: Image Navigation Order ✅ RESOLVED

**User's Answer:** C - User-configurable, with additional options (Random and Alphabetical)

**Implementation Details Added to Spec:**
- Four navigation order options: Chronological (default), Spatial, Alphabetical, Random
- Navigation order applies to both focus mode and slideshow
- User preference saved and persists across sessions
- Also added "Random" option to FR18 (Arrange Images by Criteria)

## Validation Status: ✅ COMPLETE

Specification is **READY FOR PLANNING** (`/speckit.plan`)

### Quality Summary

- **18 Functional Requirements** with detailed, testable acceptance criteria
- **7 Non-Functional Requirements** aligned with constitutional principles
- **5 User Scenarios** covering critical workflows
- **14 Success Criteria** (measurable, technology-agnostic)
- **All clarifications resolved** (no open questions)
- **696 lines** of comprehensive specification

### Constitutional Alignment Verified

- **Code Quality (Principle 1):** Modularity and separation of concerns emphasized in NFR4
- **Testing (Principle 2):** 80% coverage requirement in NFR2, all requirements have testable acceptance criteria
- **UX Consistency (Principle 3):** WCAG 2.1 AA compliance, keyboard navigation, clear error messages in NFR3
- **Performance (Principle 4):** Specific performance budgets defined in NFR1 (60fps, <200ms response, 1000 concurrent users)

### Next Steps

1. Run `/speckit.plan` to create the implementation plan
2. Plan will break down the 18 functional requirements into phased development approach
3. Technical architecture and Nix deployment strategy will be defined in planning phase
