+# Architecture Document Validation Checklist
+
+**Purpose**: Validate the architecture document itself is complete, implementable, and provides clear guidance for AI agents.
+
+**Note**: This checklist validates the ARCHITECTURE DOCUMENT only. For cross-workflow validation (PRD → Architecture → Stories alignment), use the solutioning-gate-check workflow.
+
+---
+
+## 1. Decision Completeness
+
+### All Decisions Made
+
+- [ ] Every critical decision category has been resolved
+- [ ] All important decision categories addressed
+- [ ] No placeholder text like "TBD", "[choose]", or "{TODO}" remains
+- [ ] Optional decisions either resolved or explicitly deferred with rationale
+
+### Decision Coverage
+
+- [ ] Data persistence approach decided
+- [ ] API pattern chosen
+- [ ] Authentication/authorization strategy defined
+- [ ] Deployment target selected
+- [ ] All functional requirements have architectural support
+
+---
+
+## 2. Version Specificity
+
+### Technology Versions
+
+- [ ] Every technology choice includes a specific version number
+- [ ] Version numbers are current (verified via WebSearch, not hardcoded)
+- [ ] Compatible versions selected (e.g., Node.js version supports chosen packages)
+- [ ] Verification dates noted for version checks
+
+### Version Verification Process
+
+- [ ] WebSearch used during workflow to verify current versions
+- [ ] No hardcoded versions from decision catalog trusted without verification
+- [ ] LTS vs. latest versions considered and documented
+- [ ] Breaking changes between versions noted if relevant
+
+---
+
+## 3. Starter Template Integration (if applicable)
+
+### Template Selection
+
+- [ ] Starter template chosen (or "from scratch" decision documented)
+- [ ] Project initialization command documented with exact flags
+- [ ] Starter template version is current and specified
+- [ ] Command search term provided for verification
+
+### Starter-Provided Decisions
+
+- [ ] Decisions provided by starter marked as "PROVIDED BY STARTER"
+- [ ] List of what starter provides is complete
+- [ ] Remaining decisions (not covered by starter) clearly identified
+- [ ] No duplicate decisions that starter already makes
+
+---
+
+## 4. Novel Pattern Design (if applicable)
+
+### Pattern Detection
+
+- [ ] All unique/novel concepts from PRD identified
+- [ ] Patterns that don't have standard solutions documented
+- [ ] Multi-epic workflows requiring custom design captured
+
+### Pattern Documentation Quality
+
+- [ ] Pattern name and purpose clearly defined
+- [ ] Component interactions specified
+- [ ] Data flow documented (with sequence diagrams if complex)
+- [ ] Implementation guide provided for agents
+- [ ] Edge cases and failure modes considered
+- [ ] States and transitions clearly defined
+
+### Pattern Implementability
+
+- [ ] Pattern is implementable by AI agents with provided guidance
+- [ ] No ambiguous decisions that could be interpreted differently
+- [ ] Clear boundaries between components
+- [ ] Explicit integration points with standard patterns
+
+---
+
+## 5. Implementation Patterns
+
+### Pattern Categories Coverage
+
+- [ ] **Naming Patterns**: API routes, database tables, components, files
+- [ ] **Structure Patterns**: Test organization, component organization, shared utilities
+- [ ] **Format Patterns**: API responses, error formats, date handling
+- [ ] **Communication Patterns**: Events, state updates, inter-component messaging
+- [ ] **Lifecycle Patterns**: Loading states, error recovery, retry logic
+- [ ] **Location Patterns**: URL structure, asset organization, config placement
+- [ ] **Consistency Patterns**: UI date formats, logging, user-facing errors
+
+### Pattern Quality
+
+- [ ] Each pattern has concrete examples
+- [ ] Conventions are unambiguous (agents can't interpret differently)
+- [ ] Patterns cover all technologies in the stack
+- [ ] No gaps where agents would have to guess
+- [ ] Implementation patterns don't conflict with each other
+
+---
+
+## 6. Technology Compatibility
+
+### Stack Coherence
+
+- [ ] Database choice compatible with ORM choice
+- [ ] Frontend framework compatible with deployment target
+- [ ] Authentication solution works with chosen frontend/backend
+- [ ] All API patterns consistent (not mixing REST and GraphQL for same data)

+- [ ] Implementation patterns section comprehensive
+- [ ] Novel patterns section (if applicable)
+
+### Document Quality
+
+- [ ] Source tree reflects actual technology decisions (not generic)
+- [ ] Technical language used consistently
+- [ ] Tables used instead of prose where appropriate
+- [ ] No unnecessary explanations or justifications
+- [ ] Focused on WHAT and HOW, not WHY (rationale is brief)
+
+---
+
+## 8. AI Agent Clarity
+
+### Clear Guidance for Agents
+

+- [ ] Clear boundaries between components/modules
+- [ ] Explicit file organization patterns
+- [ ] Defined patterns for common operations (CRUD, auth checks, etc.)

+- [ ] Testing patterns documented
+
+---
+
+## 9. Practical Considerations
+
+### Technology Viability

+- [ ] Standard patterns used where possible (starter templates leveraged)
+- [ ] Complex technologies justified by specific needs
+- [ ] Maintenance complexity appropriate for team size
+
+### Expert Validation
+
+- [ ] No obvious anti-patterns present
+- [ ] Performance bottlenecks addressed
+- [ ] Security best practices followed
