+
+**Feature Branch**: `001-1-target-sectors`
+**Created**: 2025-10-04
+**Status**: Draft
+**Input**: User description: "Multi-tenant SaaS platform targeting Malaysian SMEs with industry-specific modules"
+
+## Execution Flow (main)
+```
+1. Parse user description from Input
+   → If empty: ERROR "No feature description provided"
+2. Extract key concepts from description
+   → Identify: actors, actions, data, constraints
+3. For each unclear aspect:
+   → Mark with [NEEDS CLARIFICATION: specific question]
+4. Fill User Scenarios & Testing section
+   → If no clear user flow: ERROR "Cannot determine user scenarios"
+5. Generate Functional Requirements
+   → Each requirement must be testable
+   → Mark ambiguous requirements
+6. Identify Key Entities (if data involved)
+7. Run Review Checklist
+   → If any [NEEDS CLARIFICATION]: WARN "Spec has uncertainties"
+   → If implementation details found: ERROR "Remove tech details"
+8. Return: SUCCESS (spec ready for planning)
+```

+
+## ⚡ Quick Guidelines
+- ✅ Focus on WHAT users need and WHY
+- ❌ Avoid HOW to implement (no tech stack, APIs, code structure)
+- 👥 Written for business stakeholders, not developers
+
+### Section Requirements
+- **Mandatory sections**: Must be completed for every feature
+- **Optional sections**: Include only when relevant to the feature
+- When a section doesn't apply, remove it entirely (don't leave as "N/A")
+
+### For AI Generation
+When creating this spec from a user prompt:
+1. **Mark all ambiguities**: Use [NEEDS CLARIFICATION: specific question] for any assumption you'd need to make
+2. **Don't guess**: If the prompt doesn't specify something (e.g., "login system" without auth method), mark it
+3. **Think like a tester**: Every vague requirement should fail the "testable and unambiguous" checklist item
+4. **Common underspecified areas**:
+   - User types and permissions
+   - Data retention/deletion policies  
+   - Performance targets and scale
+   - Error handling behaviors
+   - Integration requirements
+   - Security/compliance needs

+
+## Clarifications
+
+### Session 2025-10-04
+- Q: What authentication method should the platform use for user access? → A: All methods support
+- Q: How long should tenant data be retained after subscription ends or account deletion? → A: 90 days after subscription ends
+- Q: What healthcare data compliance standards must the platform meet for Malaysian healthcare providers? → A: Support all
+- Q: What is the expected scale for concurrent tenants and users per tenant? → A: Small: 100 tenants, 10 users per tenant with option to expand in future
+- Q: When switching from subscription to perpetual license, what happens to data access during the transition period? → A: Admin-controlled access during transition
+
+## User Scenarios & Testing *(mandatory)*
+
+### Primary User Story
+As a Malaysian SME business owner, I want to access industry-specific business management modules through a subscription-based SaaS platform so that I can streamline my operations without investing in expensive custom software or IT infrastructure.
+
+### Acceptance Scenarios
+1. **Given** a new business owner wants to register, **When** they receive an admin registration link and complete business details, **Then** the system creates an isolated tenant space pending approval
+2. **Given** an admin approves a tenant registration, **When** approval is processed, **Then** the tenant receives credentials and can access subscribed modules
+3. **Given** a retail business user has subscribed, **When** they access their tenant dashboard, **Then** they can only use Retail & Food Stall modules based on their subscription plan
+4. **Given** a healthcare clinic has subscribed, **When** they access the system, **Then** they can manage patient records, appointments, and billing through their dedicated module
+5. **Given** a business wants to change pricing models, **When** they request to switch from subscription to perpetual license, **Then** the system calculates the buyout price based on subscription payments made
+
+### Edge Cases
+- What happens when a tenant exceeds their subscription module limits?
+- How does system handle concurrent access within the same tenant organization?
+- What happens if a tenant's subscription payment fails?
+- How does system ensure data isolation between tenants during peak usage?
+
