Complete implementation of the outbound remittance platform as a modular feature on the payment switch under internal/outbound/: Backend (Go): - Corridor routing engine: 13 Nigerian corridors, 7 providers, scoring algorithm (40% success + 25% cost + 20% latency + 15% capacity) - Sanctions screening: 7 lists (OFAC/UN/EU/CBN/INTERPOL/PEP), fuzzy matching via Levenshtein distance, decision thresholds - Tiered subscription billing: 4 tiers (Starter/Growth/Enterprise/Premium) with per-txn fees, corridor variable fees, FX revenue share - Provider adapter framework: 7 adapters (Flutterwave, WorldRemit, Chipper, Wise, MTN MoMo, Mojaloop Hub, LemFi) - Full Temporal workflow: A-G lifecycle (Admission → Compliance → Pricing → Routing → Execution → Settlement → Audit) - Unit tests covering all services Admin Dashboard (Next.js): - Outbound Remittance page with 6 tabs: Overview, Corridors, Providers, Transfers, Billing & Tiers, Sanctions - Dark theme, responsive, integrated into sidebar under Cross-Border Customer PWA (React): - Send money flow: corridor selection, amount entry, beneficiary details, review & confirm, status tracking with A-G lifecycle Flutter Mobile: - OutboundRemittanceScreen with stepper UI for the full send flow - OutboundTrackingScreen showing real-time lifecycle progress All code compiles and tests pass (go build/test, tsc --noEmit).

…lutter to B2B - Rust outbound-ledger: TigerBeetle double-entry posting engine with: - 10 account families (prefund, fees, transit, settlement, reserves) - Posting matrix for A-G lifecycle (funding, settlement, reversal) - Corridor FX engine with CBN spread caps (13 corridors) - 4 tier fee schedules (Starter/Growth/Enterprise/Premium) - 15 unit tests passing - Python outbound_compliance: Regulatory reporting & sanctions service: - Batch sanctions ingestion (7 lists: OFAC/UN/EU/CBN/INTERPOL/PEP) - Fuzzy Levenshtein matching with decision thresholds - CBN daily/monthly report generation - Corridor + participant metrics computation - 11 unit tests passing - Flutter mobile: Rewrote from consumer stepper to participant ops dashboard: - 5 tabs: Dashboard, Transfers, Prefund, Corridors, Compliance - Transaction pipeline (A-G stages with counts) - Provider health monitoring (7 providers) - Transfer management with status filters - Prefund balance + deductions tracking - Sanctions screening metrics + escalation queue All services integrated as modular features on the payment switch. Co-Authored-By: Patrick Munis <pmunis@gmail.com>
…match platform style PWA: - Left sidebar navigation with module header (Payment Switch Module) - Participant info panel showing tier and connection status - 8 sections: Dashboard, Transfers, Prefund, Billing, Corridors, Compliance, Onboarding, Settings - Stakeholder onboarding for 4 roles: Regulated Participant (Fintech/IMTO), External Provider (Payout Rail), Regulator (CBN/NFIU), Operations Staff - Each stakeholder has requirements, onboarding steps, timeline - Pending applications table with license numbers, stages, review actions - Uses shadcn/ui components (Card, Badge, Table, Button, Input, Select) matching the rest of the platform's look and feel Flutter mobile: - Added Onboarding tab (6th tab) with same stakeholder data - ExpansionTile for each stakeholder type showing requirements and steps - Pending applications list with status badges - Matches PWA feature parity Co-Authored-By: Patrick Munis <pmunis@gmail.com>
…rtal + admin review Addresses the UX gap where onboarding assumed users already had credentials. Now captures the complete lifecycle: 1. PUBLIC APPLICATION (/outbound/apply - no login required): - 4-step wizard: Select Type → Organization Details → Upload Documents → Review & Submit - Supports all 4 stakeholder types (IMTO, Provider, Regulator, Ops) - Generates application reference number - Type-specific form fields (corridors for participants, license types per role) - Document upload checklist per stakeholder type 2. ADMIN REVIEW (post-login /outbound-remittance → Onboarding tab): - Lifecycle pipeline visualization (Apply → Review → Credentials → Sandbox → Go-Live) - Tabbed interface: Stakeholder Types | Pending Applications | In Progress | Completed - Pending applications table with progress bars, reference numbers, approve/review actions - In-progress tracker for participants who received credentials but are still in sandbox - Recently completed table showing historical onboarding durations - Link to public portal for reference 3. FLUTTER MOBILE (Onboarding tab): - Same lifecycle pipeline visualization - In-progress onboarding with progress indicators - Pending applications from public portal - Stakeholder type reference with expansion tiles Co-Authored-By: Patrick Munis <pmunis@gmail.com>
… only own data CRITICAL BUSINESS LOGIC FIX: - Participants (fintechs/IMTOs) can ONLY see their own data - Admin/CBN can see all participants and system-wide metrics - Participants CANNOT see other participants' data Role-based views: 1. PARTICIPANT (fintech/IMTO logged in): - 'Your Volume', 'Your Prefund Balance', 'My Transfers' - Onboarding tab shows ONLY their own completed steps and account details - Cannot access Participant Management section - Cannot see other organizations' data 2. ADMIN (platform operator): - 'System Volume', 'Total Prefund Held', 'All Transfers' - Full Participant Management section (view/manage all 25 participants) - Onboarding Management with full lifecycle, pending applications, approve/reject - Can provision credentials, manage tiers, suspend participants 3. CBN (regulator - read-only oversight): - Same visibility as admin but READ-ONLY - No action buttons (no approve/reject/manage) - Regulatory oversight mode PWA changes: - Added role state (in production from Keycloak JWT + Permify PBAC) - Navigation items change based on role - Sidebar shows appropriate user context per role - Demo role-switcher for testing (removed in production) - ParticipantsSection (admin-only) with all registered participants - All section headers and labels are role-aware Flutter mobile changes: - Mobile app is participant-only (admins use web dashboard) - Onboarding tab now shows only the participant's own completed steps - Shows account details (license, tier, prefund account, corridors, API key) - No visibility into other participants' data Co-Authored-By: Patrick Munis <pmunis@gmail.com>
…ittance - Remove ALL mock/placeholder data arrays from OutboundRemittance.tsx - Add tRPC router (outboundRemittanceRouter) with 7 procedures: - getMyContext: returns role from Keycloak JWT ctx.user - listTransfers: WHERE participantId = ctx.user.id for non-admin - getPrefundAccounts: scoped by participant - getBilling: scoped by participant - getComplianceScreenings: scoped by participant - listParticipants: ADMIN/CBN only (throws FORBIDDEN for participants) - getDashboardMetrics: scoped by participant - Role determination from auth context (no demo switcher) - Participants see ONLY their own data - Admin/CBN see all participants' data - Added DB tables: switchParticipants, outboundTransfers, prefundAccounts, complianceScreenings, participantBilling with participantId FK - Zero TypeScript errors in outbound remittance files Co-Authored-By: Patrick Munis <pmunis@gmail.com>

…ion, build out instant-settlement service
Fix 1: Core Go settlement engine now persists batches, pending queue, and
net positions to PostgreSQL via write-through (settlement_persistence.go).
State is restored on engine startup via AttachDB(). Pure in-memory mode
preserved for unit tests (nil DB).
Fix 2: DB-backed settlement engine Reconcile() now performs real matching:
loads expected transactions and provider confirmations from DB, classifies
each leg as matched/unmatched/overpaid/underpaid, computes net discrepancy,
and updates per-transaction status. Added AddTransaction() and
RecordConfirmation() methods plus settlement_transactions and
settlement_confirmations tables.
Fix 3: instant-settlement service rebuilt from scaffold to production
service. Replaced $service_name placeholders, fixed malformed main.py,
implemented 5 real endpoints (POST /settle, GET /status/{id},
POST /confirm/{id}, GET /merchant/{id}, GET /metrics) with PostgreSQL
persistence, fee computation, idempotency, provider confirmation
reconciliation, lifecycle event emission, and real metrics.

P0: Replace all Math.random() in production TS with crypto.randomBytes/randomInt
- 48+ instances across routers, services, onboarding, risk engine
- API keys, tokens, refs now use crypto.randomBytes
- Verification codes use crypto.randomInt
- Deterministic index-based values replace random metrics
- Seed data files excluded (intentional test fixtures)
P1: Wire AML screening into remittance workflow
- Added AMLScreener interface to outbound workflow
- Replaces hardcoded 'clear' with actual AML service call
- Escalates to manual review if high_risk score
P2: Add PostgreSQL persistence to KYB service
- New PGKYBStore implementing KYBStore interface
- 3 tables: kyb_cases, kyb_documents, kyb_screening_results
- UPSERT support, proper JSON serialization
P3: Add live health data to smart router
- RecordOutcome() method updates metrics from real transactions
- AttachDB() persists health to smart_routing_health table
- Circuit breaker triggers at <90% success rate after 10 samples
P4: Replace 'In production' stubs with real implementations
- disaster_recovery: real DB ping, TCP health checks, HTTP health
- hsm_kms: config validation for all providers
- rtgs_settlement: actual HTTP POST to RTGS endpoint, real parseAmount
- security.ts: deterministic cleanup counter instead of Math.random

Caveats: Admin pages show zero-count data (Go backend not running) — UI structure renders correctly. Flutter/React Native untestable without emulator. |
… lakehouse, Kafka, Riverpod
P0: Flutter form validation — TextFormField with Validators utility class for
login (email/password), remittance (recipient/account/amount), disputes
(txn ref/reason/amount), recurring (recipient/amount), batch (name),
domestic payments (amount/account/narration). GlobalKey<FormState> wraps
all forms; submission blocked until validation passes.
P1: PWA accessibility (WCAG 2.1 AA) — skip-to-main-content link, aria-label
on all sidebar nav items, sidebar toggle, mobile menu, search input.
Breadcrumb aria-label, aria-current='page', role='navigation', role='main',
mobile drawer role='dialog' aria-modal='true'.
P2: Lakehouse CDC pipeline — Debezium connector config for PostgreSQL CDC,
bronze/silver/gold tier processing with CDCPipeline class, data quality
framework (not_null, positive, in_range, regex, enum rules), Trino
catalog views for all three tiers with materialized aggregations.
P3: Python Kafka consumers — replaced interface-only start() stubs with real
aiokafka consumption loops via _BaseConsumer. Manual offset commits,
exponential backoff reconnection, graceful shutdown, DLQ routing for
max-retry exceeded messages.
P4: Flutter state management — Riverpod providers (AuthNotifier, NotificationNotifier,
PreferencesNotifier) with StateNotifier pattern. ProviderScope already wired
in main.dart.
Also fixes 8 pre-existing TS errors: logger→log in NOCDashboard/ReportsInterface,
setSelectedCase/Person([])→null in KYB/KYC/OnboardingPortal, riskLevel comparison
cast in kycService.ts.

…econciliation services Each service gets an AttachDB(db *sql.DB) method following the established pattern (settlement, disputes, domestic, card, routing). When db is nil, services continue in pure in-memory mode for backward compatibility. - audit: audit_entries table with sequence/hash chain integrity - webhooks: webhook_subscriptions, webhook_events, webhook_deliveries tables - banking: collection_codes table for agent cash pickup - monetization: monetization_organizations, monetization_api_keys, monetization_plans tables - reconciliation: reconciliation_exceptions table for discrepancy queue Also fixes sidebar.tsx TS error (data-index property access).

Summary
Platform-wide production readiness push: persists all stateful Go services to PostgreSQL, fixes client-side non-determinism, adds Flutter validation, builds out scaffolded Python services, wires auth middleware, and adds comprehensive demo/seed data.
