TimeSafari Identity Verification Party System Plan

Objectives

Maintain strict conformity with TimeSafari's existing DID, contact, and identity management.
Ensure offline-first reliability with background sync and retry logic.
Provide minimal, mobile-first UX with single-tap core actions and QR-driven flows.

Architecture

Use a single atomic migration (005_verification_party_system.sql) following registerMigration() + MIGRATIONS array pattern.
Standardize timestamps (dateCreated, dateVerified) in ISO-8601 UTC.
Add verification_session_logs for audit trail and debugging.

Workflow

Pre-Party: Enforce RSVP via DID signing challenge; cache DID QR locally.
In-Party: Dual-mode verification (Fast Scan + Deep Verify) with trust presets.
Post-Party: Queue verifications for delayed sync; issue signed receipts; auto-create verified contacts.

Services

VerificationPartyService: Monolithic class aligned with existing service pattern.
DidVerificationService: Pluggable methods (QR, NFC, manual, photo ID).
TrustNetworkService: Add caching + trust decay unless renewed.

Security

Store hashes of evidence only (not raw PII).
Encrypt data with per-user derived keys.
Provide per-verification sharing controls (private, party-only, global).

UI/UX

Single-tap flows for RSVP, scan, verify.
Embed trust level criteria in UI to reduce inconsistency.
Optimize QR scanning and trust graph for battery savings.
Follow existing i18n service for multi-language support.

Priorities

Migration + offline queue
Dual-mode verification UI
Trust graph caching + decay
Privacy-hardened evidence handling
Notification constants + helper integration

Database Schema

Migration 005: Verification Party System

Add to src/db-sql/migration.ts in the MIGRATIONS array:

{
  name: "005_verification_party_system",
  sql: `

PlatformServiceMixin Integration

Required Methods

Add to PlatformServiceMixin:

// Add to PlatformServiceMixin methods
async $insertVerificationParty(party: Partial<VerificationParty>): Promise<boolean> {
  return this.$insertEntity('verification_parties', party, [
    'partyId', 'organizerDid', 'name', 'description', 'location', 
    'scheduledDate', 'maxParticipants', 'status', 'dateCreated'
  ]);
}

async $insertPartyParticipant(participant: Partial<PartyParticipant>): Promise<boolean> {
  return this.$insertEntity('party_participants', participant, [
    'partyId', 'participantDid', 'status', 'verificationCount',
    'rsvpDate', 'checkInDate', 'dateCreated'
  ]);
}

async $insertDidVerification(verification: Partial<DidVerification>): Promise<boolean> {
  return this.$insertEntity('did_verifications', verification, [
    'verifierDid', 'verifiedDid', 'partyId', 'verificationMethod',
    'verificationNotes', 'verificationLevel', 'verificationEvidenceHash', 'dateVerified'
  ]);
}

async $getVerificationParties(): Promise<VerificationParty[]> {
  const results = await this.$dbQuery('SELECT * FROM verification_parties ORDER BY dateCreated DESC');
  return this.$mapResults(results, (row) => ({
    id: row[0] as number,
    partyId: row[1] as string,
    organizerDid: row[2] as string,
    name: row[3] as string,
    description: row[4] as string,
    location: row[5] as string,
    scheduledDate: row[6] as string,
    maxParticipants: row[7] as number,
    status: row[8] as VerificationParty['status'],
    dateCreated: row[9] as string,
  }));
}

async $getPartyParticipants(partyId: string): Promise<PartyParticipant[]> {
  const results = await this.$dbQuery(
    'SELECT * FROM party_participants WHERE partyId = ? ORDER BY dateCreated DESC',
    [partyId]
  );
  return this.$mapResults(results, (row) => ({
    id: row[0] as number,
    partyId: row[1] as string,
    participantDid: row[2] as string,
    status: row[3] as PartyParticipant['status'],
    verificationCount: row[4] as number,
    rsvpDate: row[5] as string,
    checkInDate: row[6] as string,
    dateCreated: row[7] as string,
  }));
}

Notification Constants

Required Notification Constants

Add to src/constants/notifications.ts:

// Used in: VerificationPartyCreateView.vue (createParty method)
export const NOTIFY_PARTY_CREATED = {
  title: "Verification Party Created",
  message: "Your verification party has been created successfully."
};

// Used in: VerificationPartyJoinView.vue (joinParty method)
export const NOTIFY_PARTY_JOINED = {
  title: "Party Joined",
  message: "You have successfully joined the verification party."
};

// Used in: VerificationPartyActiveView.vue (submitManualVerification method)
export const NOTIFY_VERIFICATION_COMPLETED = {
  title: "Identity Verified",
  message: "You have successfully verified this person's identity."
};

// Used in: VerificationPartyService.ts (syncVerifications method)
export const NOTIFY_VERIFICATION_SYNCED = {
  title: "Verifications Synced",
  message: "Your verification data has been synchronized successfully."
};

// Used in: VerificationPartyActiveView.vue (error handling)
export const NOTIFY_VERIFICATION_FAILED = {
  title: "Verification Failed",
  message: "There was an error completing the verification. Please try again."
};

Notification Helper Integration

Use existing createNotifyHelpers() pattern in components:

// In VerificationPartyCreateView.vue
const { success, error } = createNotifyHelpers(this.$notify);

// Usage
success("Party created successfully!");
error("Failed to create party. Please try again.");

Component Implementation Pattern

VerificationPartyCreateView.vue Structure

@Component({
  name: "VerificationPartyCreateView",
  components: {
    QuickNav,
    TopMessage,
    EntityIcon,
  },
  mixins: [PlatformServiceMixin],
})
export default class VerificationPartyCreateView extends Vue {
  // Use PlatformServiceMixin methods
  async createParty(): Promise<void> {
    const partyData: Partial<VerificationParty> = {
      partyId: `party_${Date.now()}_${Math.random().toString(36).substr(2, 9)}`,
      organizerDid: (await this.$getActiveIdentity()).activeDid,
      name: this.partyForm.name,
      description: this.partyForm.description,
      location: this.partyForm.location,
      scheduledDate: this.partyForm.scheduledDate,
      maxParticipants: this.partyForm.maxParticipants,
      status: 'planned',
      dateCreated: new Date().toISOString(),
    };
    
    const success = await this.$insertVerificationParty(partyData);
    if (success) {
      this.$notify(NOTIFY_PARTY_CREATED);
      this.$router.push(`/verification-party/${partyData.partyId}`);
    } else {
      this.$notify(NOTIFY_VERIFICATION_FAILED);
    }
  }
}
