feat(db): implement active identity table separation
Separate activeDid from monolithic settings table into dedicated active_identity table to improve data normalization and reduce cache drift. Implements phased migration with dual-write triggers and fallback support during transition. - Add migrations 003 (create table) and 004 (drop legacy column) - Extend PlatformServiceMixin with new façade methods - Add feature flags for controlled rollout - Include comprehensive validation and error handling - Maintain backward compatibility during transition phase BREAKING CHANGE: Components should use $getActiveDid()/$setActiveDid() instead of direct settings.activeDid access

# 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
|
||||
|
||||

## 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
