# Complete Migration Checklist - MANDATORY STEPS

## Overview
This checklist ensures NO migration steps are forgotten. **Every component migration MUST complete ALL sections.**

## ⏱️ **TIME TRACKING REQUIREMENT**: All migrations must be timed and performance recorded

## ⚠️ CRITICAL: Enhanced Triple Migration Pattern

### 🔑 The Complete Pattern (ALL 4 REQUIRED)
1. **Database Migration**: Replace legacy `databaseUtil` calls with `PlatformServiceMixin` methods
2. **SQL Abstraction**: Replace raw SQL queries with service methods  
3. **Notification Migration**: Replace `$notify()` calls with helper methods + centralized constants
4. **Template Streamlining**: Extract repeated expressions and complex logic to computed properties

**❌ INCOMPLETE**: Any migration missing one of these steps
**✅ COMPLETE**: All four patterns implemented with code quality review

## Pre-Migration Assessment

### [ ] 0. Start Time Tracking
- [ ] **MANDATORY**: Run `./scripts/time-migration.sh [ComponentName.vue] start`
- [ ] Record start time in terminal output
- [ ] Keep terminal open for entire migration process

### [ ] 1. Component Complexity Assessment
- [ ] **Simple** (15-20 min): Dialog components, minimal DB operations, few notifications
- [ ] **Medium** (30-45 min): Standard views, moderate DB usage, multiple notifications
- [ ] **Complex** (45-60 min): Large views, extensive DB operations, many notifications
- [ ] Document complexity level for performance tracking

### Date Time Context
- [ ] Always use system date command to establish accurate time context
- [ ] Use time log to track project progress
- [ ] Use historical time durations to improve estimates

### [ ] 2. Identify Legacy Patterns
- [ ] Count `databaseUtil` imports and calls
- [ ] Count raw SQL queries (`SELECT`, `INSERT`, `UPDATE`, `DELETE`)
- [ ] Count `$notify()` calls
- [ ] Count `logConsoleAndDb()` calls
- [ ] Identify template complexity patterns (repeated expressions, long class strings)
- [ ] Document total issues found

### [ ] 3. Verify PlatformServiceMixin Setup
- [ ] Component already imports `PlatformServiceMixin`
- [ ] Component already has `mixins: [PlatformServiceMixin]`
- [ ] If missing, add mixin first

## Phase 1: Database Migration

### [ ] 4. Replace Database Utility Calls
- [ ] Remove `import * as databaseUtil from "../db/databaseUtil"`
- [ ] Replace `databaseUtil.retrieveSettingsForActiveAccount()` → `this.$accountSettings()`
- [ ] Replace `databaseUtil.mapQueryResultToValues()` → `this.$mapQueryResultToValues()`
- [ ] Replace other `databaseUtil.*` calls with mixin equivalents

### [ ] 5. Replace Logging Calls
- [ ] Remove `import { logConsoleAndDb } from "../db/index"`
- [ ] Replace `logConsoleAndDb()` → `this.$logAndConsole()`

## Phase 2: SQL Abstraction Migration

### [ ] 6. Replace Raw Contact Operations
- [ ] `SELECT * FROM contacts WHERE did = ?` → `this.$getContact(did)`
- [ ] `DELETE FROM contacts WHERE did = ?` → `this.$deleteContact(did)`
- [ ] `UPDATE contacts SET x = ? WHERE did = ?` → `this.$updateContact(did, changes)`
- [ ] `INSERT INTO contacts` → `this.$insertContact(contact)`

### [ ] 7. Replace Other Raw SQL
- [ ] `SELECT * FROM settings` → `this.$accountSettings()`
- [ ] `UPDATE settings` → `this.$saveSettings(changes)`
- [ ] Generic queries → appropriate service methods
- [ ] **NO RAW SQL ALLOWED**: All database operations through service layer

## Phase 3: Notification Migration

### [ ] 8. Add Notification Infrastructure
- [ ] Add import: `import { createNotifyHelpers, TIMEOUTS } from "@/utils/notify"`
- [ ] Add property: `notify!: ReturnType<typeof createNotifyHelpers>;`  
- [ ] Add initialization: `created() { this.notify = createNotifyHelpers(this.$notify); }`

### [ ] 9. Add Notification Constants to Central File
- [ ] **CRITICAL**: Add constants to `src/constants/notifications.ts` (NOT local constants)
- [ ] Use naming pattern: `NOTIFY_[COMPONENT]_[ACTION]` (e.g., `NOTIFY_OFFER_SETTINGS_ERROR`)
- [ ] Import constants: `import { NOTIFY_X, NOTIFY_Y } from "@/constants/notifications"`
- [ ] **NO LOCAL CONSTANTS**: All notification text must be centralized

### [ ] 10. Replace Notification Calls
- [ ] **Warning**: `this.$notify({type: "warning"})` → `this.notify.warning(CONSTANT.message, TIMEOUTS.LONG)`
- [ ] **Error**: `this.$notify({type: "danger"})` → `this.notify.error(CONSTANT.message, TIMEOUTS.LONG)`
- [ ] **Success**: `this.$notify({type: "success"})` → `this.notify.success(CONSTANT.message, TIMEOUTS.STANDARD)`
- [ ] **Toast**: `this.$notify({type: "toast"})` → `this.notify.toast(title, message, TIMEOUTS.SHORT)`
- [ ] **Confirm**: `this.$notify({type: "confirm"})` → `this.notify.confirm(message, onYes)`
- [ ] **Standard patterns**: Use `this.notify.confirmationSubmitted()`, `this.notify.sent()`, etc.

### [ ] 11. Constants vs Literal Strings
- [ ] **Use constants** for static, reusable messages
- [ ] **Use literal strings** for dynamic messages with variables
- [ ] **Extract literals from complex modals** - Even raw `$notify` calls should use constants for text
- [ ] **Document decision** for each notification call

## Phase 4: Template Streamlining

### [ ] 12. Identify Template Complexity Patterns
- [ ] **Repeated CSS Classes**: Long Tailwind strings used multiple times
- [ ] **Complex Configuration Objects**: Multi-line objects in template
- [ ] **Repeated Function Calls**: Same logic executed multiple times
- [ ] **Complex Conditional Logic**: Nested ternary or complex boolean expressions

### [ ] 13. Extract to Computed Properties
- [ ] **CSS Class Groups**: Extract repeated styling to computed properties
- [ ] **Configuration Objects**: Move router configs, form configs to computed
- [ ] **Conditional Logic**: Extract complex `v-if` conditions to computed properties
- [ ] **Dynamic Values**: Convert repeated calculations to cached computed properties

### [ ] 14. Document Computed Properties
- [ ] **JSDoc Comments**: Add comprehensive comments for all computed properties
- [ ] **Purpose Documentation**: Explain what template complexity each property solves
- [ ] **Organized Sections**: Group related computed properties with section headers
- [ ] **Descriptive Names**: Use clear, descriptive names for computed properties

## Phase 5: Code Quality Review

### [ ] 15. Template Quality Assessment
- [ ] **Readability**: Template is easy to scan and understand
- [ ] **Maintainability**: Styling changes can be made in one place
- [ ] **Performance**: Computed properties cache expensive operations
- [ ] **Consistency**: Similar patterns use similar solutions

### [ ] 16. Component Architecture Review
- [ ] **Single Responsibility**: Component has clear, focused purpose
- [ ] **Props Interface**: Clear, well-documented component props
- [ ] **Event Emissions**: Appropriate event handling and emission
- [ ] **State Management**: Component state is minimal and well-organized

### [ ] 17. Code Organization Review
- [ ] **Import Organization**: Imports are grouped logically (Vue, constants, services)
- [ ] **Method Organization**: Methods are grouped by purpose with section headers
- [ ] **Property Organization**: Data properties are documented and organized
- [ ] **Comment Quality**: All complex logic has explanatory comments

## Validation Phase

### [ ] 18. Run Validation Script
- [ ] Execute: `scripts/validate-migration.sh`
- [ ] **MUST show**: "Technically Compliant" (not "Mixed Pattern")
- [ ] **Zero** legacy patterns detected

### [ ] 19. Run Linting
- [ ] Execute: `npm run lint-fix`
- [ ] **Zero errors** introduced
- [ ] **TypeScript compiles** without errors

### [ ] 20. Manual Code Review
- [ ] **NO** `databaseUtil` imports or calls
- [ ] **NO** raw SQL queries (`SELECT`, `INSERT`, `UPDATE`, `DELETE`)
- [ ] **NO** `$notify()` calls with object syntax
- [ ] **NO** `logConsoleAndDb()` calls
- [ ] **NO** local notification constants
- [ ] **ALL** database operations through service methods
- [ ] **ALL** notifications through helper methods with centralized constants
- [ ] **ALL** complex template logic extracted to computed properties

## ⏱️ Time Tracking & Commit Phase

### [ ] 21. End Time Tracking
- [ ] **MANDATORY**: Run `./scripts/time-migration.sh [ComponentName.vue] end`
- [ ] Record total duration from terminal output
- [ ] Note any blockers or issues that impacted timing

### [ ] 22. Commit with Time Data
- [ ] **MANDATORY**: Include time data in commit message
- [ ] Use template: `Complete [ComponentName] Enhanced Triple Migration Pattern (X minutes)`
- [ ] Include complexity level and any issues encountered
- [ ] Document specific changes made in each phase

### [ ] 23. Performance Analysis
- [ ] Compare actual time vs. estimated time for complexity level
- [ ] Note if component was faster/slower than expected
- [ ] Document any efficiency improvements discovered

## Documentation Phase

### [ ] 24. Update Migration Documentation
- [ ] Create `docs/migration-testing/[COMPONENT]_MIGRATION.md`
- [ ] Document all changes made (database, SQL, notifications, template)
- [ ] Include before/after examples for template streamlining
- [ ] Note validation results and timing data
- [ ] Provide a guide to finding the components in the user interface
- [ ] Include code quality review notes

### [ ] 25. Update Testing Tracker
