# ActiveDid Table Separation Progress Report

**Author**: Matthew Raymer  
**Date**: 2025-08-21T12:32Z  
**Status**: 🔍 **INVESTIGATION COMPLETE** - Ready for implementation planning

## Executive Summary

This document tracks the investigation and progress of separating the `activeDid` field
from the `settings` table into a dedicated `active_identity` table. The project aims
to improve data integrity, reduce cache drift, and simplify transaction logic for
identity management in TimeSafari.

## Investigation Results

### Reference Audit Findings

**Total ActiveDid References**: 505 across the codebase

- **Write Operations**: 100 (20%)
- **Read Operations**: 260 (51%)
- **Other References**: 145 (29%) - includes type definitions, comments, etc.

**Component Impact**: 15+ Vue components directly access `settings.activeDid`

### Current Database Schema

The `settings` table currently contains **30 fields** mixing identity state with user
preferences:

```sql
CREATE TABLE IF NOT EXISTS settings (
  id INTEGER PRIMARY KEY AUTOINCREMENT,
  accountDid TEXT,           -- Links to identity (null = master)
  activeDid TEXT,            -- Current active identity (master only)
  apiServer TEXT,            -- API endpoint
  filterFeedByNearby BOOLEAN,
  filterFeedByVisible BOOLEAN,
  finishedOnboarding BOOLEAN,
  firstName TEXT,            -- User's name
  hideRegisterPromptOnNewContact BOOLEAN,
  isRegistered BOOLEAN,
  lastName TEXT,             -- Deprecated
  lastAckedOfferToUserJwtId TEXT,
  lastAckedOfferToUserProjectsJwtId TEXT,
  lastNotifiedClaimId TEXT,
  lastViewedClaimId TEXT,
  notifyingNewActivityTime TEXT,
  notifyingReminderMessage TEXT,
  notifyingReminderTime TEXT,
  partnerApiServer TEXT,
  passkeyExpirationMinutes INTEGER,
  profileImageUrl TEXT,
  searchBoxes TEXT,          -- JSON string
  showContactGivesInline BOOLEAN,
  showGeneralAdvanced BOOLEAN,
  showShortcutBvc BOOLEAN,
  vapid TEXT,
  warnIfProdServer BOOLEAN,
  warnIfTestServer BOOLEAN,
  webPushServer TEXT
);
```

### Component State Management

#### PlatformServiceMixin Cache System

- **`_currentActiveDid`**: Component-level cache for activeDid
- **`$updateActiveDid()`**: Method to sync cache with database
- **Change Detection**: Watcher triggers component updates on activeDid changes
- **State Synchronization**: Cache updates when `$saveSettings()` changes activeDid

#### Common Usage Patterns

```typescript
// Standard pattern across 15+ components
this.activeDid = settings.activeDid || "";

// API header generation
const headers = await getHeaders(this.activeDid);

// Identity validation
if (claim.issuer === this.activeDid) { ... }
```

### Migration Infrastructure Status

#### Existing Capabilities

- **`migrateSettings()`**: Fully implemented and functional
- **Settings Migration**: Handles 30 fields with proper type conversion
- **Data Integrity**: Includes validation and error handling
- **Rollback Capability**: Migration service has rollback infrastructure

#### Migration Order

1. **Accounts** (foundational - contains DIDs)
2. **Settings** (references accountDid, activeDid)
3. **ActiveDid** (depends on accounts and settings)
4. **Contacts** (independent, but migrated after accounts)

### Testing Infrastructure

#### Current Coverage

- **Playwright Tests**: `npm run test:web` and `npm run test:mobile`
- **No Unit Tests**: Found for migration or settings management
- **Integration Tests**: Available through Playwright test suite
- **Platform Coverage**: Web, Mobile (Android/iOS), Desktop (Electron)

## Risk Assessment

### High Risk Areas

1. **Component State Synchronization**: 505 references across codebase
2. **Cache Drift**: `_currentActiveDid` vs database `activeDid`
3. **Cross-Platform Consistency**: Web + Mobile + Desktop

### Medium Risk Areas

1. **Foreign Key Constraints**: activeDid → accounts.did relationship
2. **Migration Rollback**: Complex 30-field settings table
3. **API Surface Changes**: Components expect `settings.activeDid`

### Low Risk Areas

1. **Migration Infrastructure**: Already exists and functional
2. **Data Integrity**: Current migration handles complex scenarios
3. **Testing Framework**: Playwright tests available for validation

## Implementation Phases

### Phase 1: Foundation Analysis ✅ **COMPLETE**

- [x] **ActiveDid Reference Audit**: 505 references identified and categorized
- [x] **Database Schema Analysis**: 30-field settings table documented
- [x] **Component Usage Mapping**: 15+ components usage patterns documented
- [x] **Migration Infrastructure Assessment**: Existing service validated

### Phase 2: Design & Implementation (Medium Complexity)

- [ ] **New Table Schema Design**
  - Define `active_identity` table structure
  - Plan foreign key relationships to `accounts.did`
  - Design migration SQL statements
  - Validate against existing data patterns

- [ ] **Component Update Strategy**
  - Map all 505 references for update strategy
  - Plan computed property changes
  - Design state synchronization approach
  - Preserve existing API surface

- [ ] **Testing Infrastructure Planning**
  - Unit tests for new table operations
  - Integration tests for identity switching
  - Migration rollback validation
  - Cross-platform testing strategy

### Phase 3: Migration & Validation (Complex Complexity)

- [ ] **Migration Execution Testing**
  - Test on development database
  - Validate data integrity post-migration
  - Measure performance impact
  - Test rollback scenarios

- [ ] **Cross-Platform Validation**
  - Web platform functionality
  - Mobile platform functionality
  - Desktop platform functionality
  - Cross-platform consistency

- [ ] **User Acceptance Testing**
  - Identity switching workflows
  - Settings persistence
  - Error handling scenarios
  - Edge case validation

## Technical Requirements

### New Table Schema

```sql
-- Proposed active_identity table
CREATE TABLE IF NOT EXISTS active_identity (
  id INTEGER PRIMARY KEY AUTOINCREMENT,
  activeDid TEXT NOT NULL,
  lastUpdated TEXT NOT NULL,
  FOREIGN KEY (activeDid) REFERENCES accounts(did)
);

-- Index for performance
CREATE INDEX IF NOT EXISTS idx_active_identity_activeDid ON active_identity(activeDid);
```

### Migration Strategy

1. **Extract activeDid**: Copy from settings table to new table
2. **Update References**: Modify components to use new table
3. **Remove Field**: Drop activeDid from settings table
4. **Validate**: Ensure data integrity and functionality

### Component Updates Required
