+# RemitFlow — Incident Response Procedure
+
+## Severity Classification
+
+| Level | Definition | Response Time | Example |
+|-------|-----------|---------------|---------|
+| **SEV1** | Service fully down, funds at risk | 5 min | Ledger imbalance, all transfers failing |
+| **SEV2** | Major feature degraded, some users impacted | 15 min | One corridor down, high error rate |
+| **SEV3** | Minor degradation, workaround exists | 1 hour | Slow quotes, analytics delayed |
+| **SEV4** | Cosmetic / informational | Next business day | Dashboard rendering issue |
+
+## Incident Lifecycle
+
+```
+DETECT → TRIAGE → MITIGATE → RESOLVE → POST-MORTEM
+  │         │         │          │           │
+  │         │         │          │           └─ Within 48h
+  │         │         │          └─ Fix root cause
+  │         │         └─ Stop bleeding (failover, rollback, hold)
+  │         └─ Assess severity, assign IC
+  └─ Alert fires or user reports
+```
+
+## Roles
+
+| Role | Responsibility |
+|------|---------------|
+| **Incident Commander (IC)** | Coordinates response, makes decisions, communicates |
+| **Tech Lead** | Investigates root cause, implements fix |
+| **Comms Lead** | Updates status page, notifies affected users |
+| **Finance Lead** | Assesses financial impact, authorizes compensations |
+
+## Step-by-Step Response
+
+### 1. DETECT (Automated)
+- Prometheus alert fires → PagerDuty pages on-call
+- User reports via support channel
+- Automated monitoring detects anomaly
+
+### 2. TRIAGE (First 5 minutes)
+```
+IC Checklist:
+□ Acknowledge alert in PagerDuty
+□ Open incident channel: #incident-YYYY-MM-DD-<title>
+□ Assess severity (SEV1-4)
+□ Page additional responders if needed
+□ Post initial status: "Investigating [symptom]"
+```
+
+### 3. MITIGATE (Stop the bleeding)
+
+**For transfer failures:**
+```bash
+# Option A: Activate kill switch (stops new transfers)
+curl -X POST http://temporal:7233/kill-switch/activate
+
+# Option B: Failover to backup rail
+curl -X POST http://localhost:8125/admin/failover -d '{"rail":"<affected>","backup":"<backup>"}'
+
+# Option C: Rollback last deployment
+kubectl argo rollouts abort remitflow-api -n remitflow
+```
+
+**For ledger issues:**
+```bash
+# Halt all financial operations
+curl -X POST http://localhost:3001/api/admin/maintenance-mode -d '{"enabled":true}'
+```
+
+**For security incidents:**
+```bash
+# Revoke compromised credentials
+curl -X POST http://keycloak:8080/admin/revoke-all-sessions
+# Activate WAF emergency rules
+curl -X POST http://apisix:9180/apisix/admin/routes/emergency-block
+```
+
+### 4. RESOLVE (Root cause fix)
+- Identify root cause using runbooks
+- Implement fix (code change, config update, infrastructure fix)
+- Deploy fix through canary pipeline (fast-track for SEV1)
+- Verify fix resolves the issue
+- Verify no secondary effects
+
+### 5. POST-MORTEM (Within 48 hours)
+
+Template:
+```markdown

+### Status Page Update (SEV1)
+```
+[Investigating] We are aware of an issue affecting [transfers/payments/logins]
+in [corridor/region]. Our team is actively investigating.
+
+[Identified] The issue has been identified as [brief description].
+We are working on a fix.
+
+[Monitoring] A fix has been deployed. We are monitoring to confirm resolution.
+
+[Resolved] The issue has been fully resolved.
+[X] transfers were affected and have been [completed/refunded].
+```
+
+### User Notification (Delayed Transfer)
+```
+Your transfer of [amount] [currency] to [recipient] is taking longer
+than expected. We're working to complete it as soon as possible.
+You will receive a confirmation once delivery is complete.
+If not resolved within [timeframe], your funds will be automatically refunded.
+Reference: [transfer_id]

+# Runbook: Ledger Imbalance
+
+**Alert:** `LedgerImbalance`
+**Severity:** CRITICAL — Page immediately
+**Impact:** Potential fund loss, duplication, or accounting error
+**SLO:** Debits - Credits = 0 at all times (zero tolerance)
+
+## Symptoms
+
+- Alert fires when `abs(sum(tigerbeetle_debits_total) - sum(tigerbeetle_credits_total)) > 0`
+- Dashboard shows non-zero value in "TigerBeetle Ledger Balance" panel
+- Users may report missing or extra funds
+
+## Immediate Actions (First 5 minutes)
+
+1. **HALT all new transfers** — prevent further imbalance:
+   ```bash
+   # Activate kill switch via Temporal
+   curl -X POST http://temporal:7233/api/v1/namespaces/default/workflows \
+     -d '{"workflowId":"kill-switch","workflowType":{"name":"haltTransfers"}}'
+   ```
+
+2. **Identify the imbalanced account(s)**:
+   ```sql
+   -- Find accounts where debits != credits
+   SELECT account_id,
+          sum(debit_amount) as debits,
+          sum(credit_amount) as credits,
+          sum(debit_amount) - sum(credit_amount) as imbalance
+   FROM tigerbeetle_journal
+   GROUP BY account_id
+   HAVING sum(debit_amount) != sum(credit_amount)
+   ORDER BY abs(sum(debit_amount) - sum(credit_amount)) DESC
+   LIMIT 20;
+   ```
+
+3. **Check recent transfer failures**:
+   ```sql
+   SELECT * FROM transfers
+   WHERE status IN ('failed', 'compensating', 'stuck')
+   AND created_at > now() - interval '1 hour'
+   ORDER BY created_at DESC;
+   ```
+
+4. **Check dead letter queue**:
+   ```bash
+   kafka-console-consumer --bootstrap-server kafka:9092 \
+     --topic remitflow.dlq \
+     --from-beginning --max-messages 10
+   ```
+
+## Investigation
+
+### Common Causes
+
+| Cause | How to Identify | Resolution |
+|-------|----------------|------------|
+| Failed saga compensation | Transfer status = 'failed' but no reversal entry | Manually create reversal entry |
+| Duplicate credit | Two credits for same transfer ID | Delete duplicate, verify with user |
+| Race condition | Concurrent transfers to same account | Review timestamps, apply locking |
+| External rail timeout | Fiat payout submitted but settlement unknown | Check rail provider portal |
+
+### Diagnostic Queries
+
+```sql
+-- Find the exact transfer(s) causing imbalance
+SELECT t.id, t.amount, t.status, t.corridor,
+       j.debit_amount, j.credit_amount
+FROM transfers t
+LEFT JOIN tigerbeetle_journal j ON t.id = j.transfer_id
+WHERE t.created_at > now() - interval '2 hours'
+AND (j.debit_amount IS NULL OR j.credit_amount IS NULL
+     OR j.debit_amount != j.credit_amount);
+```
+
+## Resolution Steps
+
+1. **For failed compensation**: Create manual reversal entry
+   ```bash
+   # Use TB admin CLI
+   tigerbeetle-admin create-transfer \
+     --debit-account <credited_account> \
+     --credit-account <debited_account> \
+     --amount <imbalance_amount> \
+     --flags compensation \
+     --user-data "manual-fix-$(date +%s)"
+   ```
+
+2. **For duplicate**: Void the duplicate entry (append-only — add negation)
+
+3. **After fix**: Verify balance is zero again
+   ```bash
+   curl http://localhost:3001/api/services/health | jq '.tigerbeetle.balance'
+   ```
+
+4. **Resume transfers**:
+   ```bash
+   curl -X POST http://temporal:7233/api/v1/namespaces/default/workflows \
+     -d '{"workflowId":"kill-switch","workflowType":{"name":"resumeTransfers"}}'
+   ```
+
+## Escalation
+
+- If imbalance > $10,000: Notify CFO immediately
+- If imbalance persists > 30 minutes: Engage TigerBeetle support
+- If user funds affected: Notify compliance team for SAR consideration
+
+## Post-Incident

+# Runbook: Low Transfer Success Rate
+
+**Alert:** `TransferSuccessRateLow`
+**Severity:** CRITICAL
+**Impact:** Fund delivery failing; SLO breach
+**SLO:** 99.9% transfer success rate
+
+## Immediate Actions
+
+1. **Assess scope**:
+   ```sql
+   SELECT corridor, count(*) as failed, count(*) * 100.0 / 
+     (SELECT count(*) FROM transfers WHERE created_at > now() - interval '1 hour') as pct
+   FROM transfers
+   WHERE status = 'failed' AND created_at > now() - interval '1 hour'
+   GROUP BY corridor ORDER BY failed DESC;
+   ```
+
+2. **Check error breakdown**:
+   ```sql
+   SELECT error_code, count(*) FROM transfers
+   WHERE status = 'failed' AND created_at > now() - interval '1 hour'
+   GROUP BY error_code ORDER BY count DESC;
+   ```
+
+3. **Check external service health**:
+   ```bash
+   curl http://localhost:3001/api/services/health | jq '.'
+   curl http://localhost:8125/health | jq '.'
+   ```
+
+## Common Error Codes
+
+| Code | Meaning | Action |
+|------|---------|--------|
+| `RAIL_TIMEOUT` | Payment rail not responding | Failover to backup |
+| `INSUFFICIENT_BALANCE` | LP pool depleted | Top up liquidity |
+| `SANCTIONS_HIT` | Sanctions screening flagged | Review manually |
+| `KYC_EXPIRED` | User KYC needs renewal | Notify user |
+| `RATE_EXPIRED` | FX quote expired before execution | Reduce quote TTL |
+| `TB_ERROR` | TigerBeetle ledger error | Check TB cluster |
+
+## Resolution
+
+1. Fix the root cause per error code table above
+2. Retry failed transfers: `UPDATE transfers SET status = 'retry' WHERE status = 'failed' AND error_code = '<fixable_code>' AND created_at > now() - interval '1 hour';`
+3. Monitor success rate recovering above 99.9%
+4. Compensate users with >10 min delay

+# Runbook: Payment Rail Provider Down
+
+**Alert:** `RailProviderDown`
+**Severity:** CRITICAL
+**Impact:** Transfers on affected corridor(s) will fail
+**SLO:** 99.9% rail availability
+
+## Symptoms
+
+- `rail_provider_health == 0` for specific rail
+- Circuit breaker in OPEN state for the rail
+- Transfers to affected corridor returning errors
+- Settlement queue growing for that rail
+
+## Payment Rails & Backup Strategy
+
+| Rail | Provider | Corridors | Backup Rail | Backup Provider |
+|------|----------|-----------|-------------|-----------------|
+| ACH | Stripe | US domestic | Wire | Banking Circle |
+| SEPA | Banking Circle | EU corridors | SWIFT | Wise Business |
+| SWIFT | Wise Business | International | — | Manual settlement |
+| NIBSS | Flutterwave | NG domestic | Paystack | Paystack |
+| M-Pesa | Safaricom | KE corridors | Airtel Money | Airtel |
+| MTN MoMo | MTN | GH, UG, CM | — | Manual |
+| Mojaloop | Hub | Cross-border | PAPSS | PAPSS Hub |
+| PAPSS | PAPSS Hub | Pan-African | — | Manual |
+
+## Immediate Actions
+
+1. **Confirm rail is actually down** (not just a timeout):
+   ```bash
+   # Check circuit breaker state
+   curl http://localhost:8125/health | jq '.rails'
+   
+   # Direct provider health check
+   curl -s -o /dev/null -w "%{http_code}" https://api.flutterwave.com/v3/health
+   curl -s -o /dev/null -w "%{http_code}" https://api.paystack.co/health
+   ```
+
+2. **Activate backup rail** (if available):
+   ```bash
+   curl -X POST http://localhost:8125/admin/failover \
+     -H "Content-Type: application/json" \
+     -d '{
+       "rail": "nibss",
+       "action": "failover",
+       "backup": "paystack"
+     }'
+   ```
+
+3. **Hold new transfers on affected corridor** (if no backup):
+   ```bash
+   curl -X POST http://localhost:3001/api/admin/corridor-hold \
+     -H "Content-Type: application/json" \
+     -d '{"corridor": "US-NG", "reason": "rail_provider_down", "hold": true}'
+   ```
+
+4. **Notify users with pending transfers**:
+   ```bash
+   # Trigger notification for users with in-flight transfers on this rail
+   curl -X POST http://localhost:3001/api/admin/notify-delay \
+     -d '{"rail": "nibss", "estimated_delay_minutes": 30}'
+   ```
+
+## Resolution
+
+### When provider recovers:
+
+1. Run health check to confirm:
+   ```bash
+   curl http://localhost:8125/health | jq '.rails.nibss'
+   ```
+
+2. Close circuit breaker manually (or wait for half-open probe):
+   ```bash
+   curl -X POST http://localhost:8125/admin/circuit-breaker \
+     -d '{"rail": "nibss", "action": "close"}'
+   ```
+
+3. Process stuck settlement queue:
+   ```bash
+   curl -X POST http://localhost:8125/admin/flush-queue \
+     -d '{"rail": "nibss"}'
+   ```
+
+4. Verify transfers completing:
+   ```bash
+   watch 'curl -s http://localhost:3001/metrics/features | grep settlement_queue_depth'
+   ```
+
+5. Release corridor hold:
+   ```bash
+   curl -X POST http://localhost:3001/api/admin/corridor-hold \
+     -d '{"corridor": "US-NG", "hold": false}'
+   ```
+
+## Escalation
+
+- If backup rail also fails: Engage manual settlement team
+- If downtime > 4 hours: Notify CBN/FCA (regulatory reporting obligation)
+- If user funds at risk: Activate compensation workflow for refunds

+# Runbook: Sanctions Screening Down
+
+**Alert:** `SanctionsScreeningDown`
+**Severity:** CRITICAL
+**Impact:** REGULATORY — all transfers must be held until resolved
+**Legal:** CBN AML/CFT, FATF Recommendation 6, FCA Financial Sanctions
+
+## ⚠️ REGULATORY REQUIREMENT
+
+Transfers MUST NOT be processed without sanctions screening. Proceeding without screening is a regulatory violation that can result in license revocation.
+
+## Immediate Actions
+
+1. **HOLD all pending transfers** (automatic if circuit breaker is working):
+   ```bash
+   curl -X POST http://localhost:3001/api/admin/sanctions-hold \
+     -d '{"action":"hold","reason":"screening_service_unavailable"}'
+   ```
+
+2. **Check screening provider status**:
+   ```bash
+   # OFAC
+   curl -s -o /dev/null -w "%{http_code}" https://sanctionssearch.ofac.treas.gov/
+   # UN
+   curl -s -o /dev/null -w "%{http_code}" https://scsanctions.un.org/
+   ```
+
+3. **Check circuit breaker**:
+   ```bash
+   curl http://localhost:3001/metrics/features | grep circuit_breaker | grep sanctions
+   ```
+
+4. **Notify compliance team** immediately — this is a mandatory escalation.
+
+## Resolution
+
+1. When provider recovers, close circuit breaker
+2. Process held transfers through screening
+3. Release transfers that pass
+4. File SARs for any flagged during batch screening
+5. Document the outage for regulatory reporting
+
+## Fallback
+
+If primary provider (OFAC API) is down > 30 minutes:
+- Switch to cached sanctions list (must be < 24 hours old)
+- Log all transfers processed against cached list
+- Re-screen against live list when available
+
+**Never bypass screening entirely.**
+
+## Escalation
+
+- Immediately: Compliance Officer
+- > 30 minutes: Chief Compliance Officer
+- > 2 hours: External legal counsel
+- > 4 hours: Regulatory notification (CBN, FCA as applicable)

+# Runbook: Slow Fund Delivery
+
+**Alert:** `TransferDeliverySlowP95`
+**Severity:** WARNING
+**Impact:** User experience degraded; SLO breach risk
+**SLO:** p95 delivery < 30 seconds
+
+## Symptoms
+
+- Transfer delivery p95 latency exceeding 30 seconds
+- Users complaining about slow transfers
+- Settlement queue growing
+
+## Investigation
+
+1. **Identify slow corridor(s)**:
+   ```promql
+   histogram_quantile(0.95, sum(rate(transfer_delivery_duration_seconds_bucket[5m])) by (le, corridor))
+   ```
+
+2. **Check if it's a specific rail**:
+   ```bash
+   curl http://localhost:8125/health | jq '.rails'
+   ```
+
+3. **Check settlement queue depth**:
+   ```bash
+   curl http://localhost:3001/metrics/features | grep settlement_queue
+   ```
+
+## Common Causes & Fixes
+
+| Cause | Fix |
+|-------|-----|
+| Rail provider slow | Monitor; failover if > 5 min |
+| High transaction volume | Scale settlement workers |
+| DB query slow | Check PostgreSQL slow query log |
+| Kafka consumer lag | Scale consumers |
+| TigerBeetle contention | Check TB cluster health |
+
+## Resolution
+
+1. If single rail: Consider temporary failover
+2. If all corridors: Check shared infrastructure (DB, Kafka, TB)
+3. Scale settlement workers if queue depth is growing
+4. After resolution: Verify p95 returns below 30s

+# Runbook: Stuck Transfers
+
+**Alert:** `TransferStuckInFlight`
+**Severity:** CRITICAL
+**Impact:** Users' funds are locked; delivery delayed
+**SLO:** 99.9% of transfers complete within 30 seconds
+
+## Symptoms
+
+- Transfers initiated but not completing
+- `transfers_in_flight` metric growing without `transfers_completed_total` increasing
+- Users reporting "pending" status for extended periods
+- Settlement queue growing
+
+## Immediate Actions (First 5 minutes)
+
+1. **Assess scope** — how many transfers are stuck:
+   ```sql
+   SELECT corridor, count(*), min(created_at) as oldest
+   FROM transfers
+   WHERE status = 'in_flight'
+   AND created_at < now() - interval '5 minutes'
+   GROUP BY corridor;
+   ```
+
+2. **Check Temporal workflows**:
+   ```bash
+   # List stuck workflows
+   tctl workflow list --query "ExecutionStatus='Running' AND StartTime < '2024-01-01'"
+   ```
+
+3. **Check external rail health**:
+   ```bash
+   curl http://localhost:8125/health  # Go fiat rails service
+   curl http://localhost:3001/api/services/health | jq '.services'
+   ```
+
+4. **Check circuit breaker status**:
+   ```bash
+   curl http://localhost:3001/metrics/features | grep circuit_breaker
+   ```
+
+## Investigation
+
+### Decision Tree
+
+```
+Stuck transfers found
+├── All same corridor?
+│   ├── YES → Rail provider issue (check provider status page)
+│   └── NO → Platform-level issue
+│       ├── Temporal worker down?
+│       │   ├── YES → Restart Temporal worker
+│       │   └── NO → Check DB/Kafka/TigerBeetle
+│       ├── Kafka consumer lag?
+│       │   ├── YES → Scale consumers or check processing errors
+│       │   └── NO → Check TigerBeetle connectivity
+│       └── TigerBeetle unreachable?
+│           ├── YES → Restart TB sidecar, check TB cluster health
+│           └── NO → Check application logs for errors
+```
+
+### Common Causes
+
+| Cause | Indicator | Fix |
+|-------|-----------|-----|
+| Rail provider down | All stuck in one corridor | Wait for provider, activate backup rail |
+| Temporal worker crashed | No workflow activity | Restart worker: `systemctl restart temporal-worker` |
+| Kafka consumer stuck | High consumer lag | Reset offset or restart consumer |
+| DB connection exhausted | Connection pool errors in logs | Restart API, increase pool size |
+| TigerBeetle timeout | TB errors in application logs | Restart TB sidecar |
+
+## Resolution
+
+### Option A: Retry stuck transfers
+```bash
+# For transfers stuck < 30 minutes
+psql -c "UPDATE transfers SET status = 'retry' WHERE status = 'in_flight' AND created_at < now() - interval '5 minutes' AND created_at > now() - interval '30 minutes';"
+# Temporal will pick up retries automatically
+```
+
+### Option B: Force-complete with compensation
+```bash
+# For transfers stuck > 30 minutes — refund to sender
+psql -c "UPDATE transfers SET status = 'compensating' WHERE status = 'in_flight' AND created_at < now() - interval '30 minutes';"
+# Compensation workflow will reverse the debit and notify user
+```
+
+### Option C: Rail failover
+```bash
+# Switch corridor to backup rail
+curl -X POST http://localhost:8125/admin/failover \
+  -d '{"corridor":"US-NG","primary_rail":"flutterwave","backup_rail":"paystack"}'
+```
+
+## Post-Resolution
+
+1. Verify `transfers_in_flight` metric decreasing
+2. Check affected users received funds or refunds
+3. Verify ledger balance is still zero
+4. Send user notifications for delayed transfers
+
+## Escalation
+
+- If > 1000 transfers stuck: Activate incident bridge
+- If > $100K in stuck funds: Notify CFO + Compliance
+- If rail provider unresponsive > 1 hour: Activate manual settlement process

+# RemitFlow — Quality Assurance Suite
+
+Comprehensive QA framework ensuring **accuracy, security, and guaranteed fund delivery** for the RemitFlow financial platform.
+
+## Quick Start
+
+```bash
+# Run everything locally
+make -f qa/Makefile all
+
+# Run specific suite
+make -f qa/Makefile security
+make -f qa/Makefile load BASE_URL=https://staging.remitflow.io
+make -f qa/Makefile compliance
+```
+
+## Suite Overview
+
+| Suite | Purpose | Frequency | CI Job |
+|-------|---------|-----------|--------|
+| **Unit Tests** | tRPC endpoint correctness, business logic | Every PR | `qa-pipeline / unit-tests` |
+| **Security Scan** | OWASP Top 10, dependency vulns, contract audit | Every PR | `qa-pipeline / security` |
+| **Load Testing** | 10K concurrent users, p95 < 500ms | Nightly | `qa-pipeline / load-testing` |
+| **Soak Testing** | 30-min sustained load, memory leak detection | Nightly | `nightly-soak` |
+| **Financial Reconciliation** | Zero discrepancy tolerance on money flow | Nightly + Every PR | `qa-pipeline / load-testing` |
+| **Chaos Engineering** | Service kill, network partition, DB exhaust | Nightly | `qa-pipeline / chaos-engineering` |
+| **Disaster Recovery** | PG backup/restore, Redis rebuild, full restore | Weekly | `qa-pipeline / disaster-recovery` |
+| **Compliance** | CBN, FCA, FATF, PCI-DSS regulatory checks | Every PR | `qa-pipeline / compliance` |
+| **Canary Verification** | Pre-promotion health + latency + ledger check | Every deploy | `deploy-gate / deploy` |
+

+## CI/CD Integration
+
+### GitHub Actions Workflows
+
+| Workflow | Trigger | Duration |
+|----------|---------|----------|
+| `qa-pipeline.yml` | Push, PR, nightly, manual | ~15 min |
+| `nightly-soak.yml` | 3am UTC daily | ~35 min |
+| `deploy-gate.yml` | Manual (pre-deploy) | ~10 min |
+
+### Running in CI
+
+All scripts are self-contained and exit with appropriate codes:
+- `exit 0` = passed
+- `exit 1` = failed (blocks deployment)
+
+Scripts produce JSON reports in their respective `results/` directories for artifact collection.
+
+### Thresholds
+
+| Metric | Threshold | Enforcement |
+|--------|-----------|-------------|
+| p95 latency | < 500ms | k6 threshold (hard fail) |
+| Error rate | < 1% | k6 threshold (hard fail) |
+| Financial discrepancies | 0 | k6 threshold (zero tolerance) |
+| Critical npm vulns | 0 | Security gate (hard fail) |
+| Compliance failures | 0 | Compliance gate (hard fail) |
+| Ledger imbalance | 0 | Canary analysis (instant rollback) |
+
+## Financial Integrity Guarantees
+
+1. **Double-Entry Verification**: Every debit has a matching credit (TigerBeetle)
+2. **Reconciliation Tests**: Automated checks that `sum(debits) == sum(credits)`
+3. **Swap Symmetry**: Forward rate × reverse rate ≈ 1 (within spread)
+4. **Batch Totals**: Sum of recipients = reported total (zero tolerance)
+5. **Fee Accuracy**: Calculated fees match quoted fees exactly
+6. **Settlement Matching**: Payout amounts match expected after FX conversion
+
+## Adding New Tests
+
+1. Create script in appropriate directory
+2. Make it executable and self-contained (accepts `BASE_URL` parameter)
+3. Exit with code 1 on failure
+4. Write JSON report to `results/` directory
+5. Add Makefile target
+6. Add to appropriate CI workflow job

+ * markLaneRouter.ts — tRPC Router for Mark Lane Integration
+ *
+ * Provides endpoints for:
+ *   - Canadian corridor FX quotes (CAD→USD→NGN/GHS/KES/ZAR)
+ *   - Transfer initiation via Mark Lane's on-ramp
+ *   - KYC passport management (FINTRAC ↔ CBN/FCA bridge)
+ *   - Nostro balance monitoring
+ *   - Webhook ingestion for transfer status updates
+ *   - FX professional channel management
+ *
+ * All endpoints use DB write-through (PostgreSQL), TigerBeetle ledger
+ * entries for financial mutations, and Kafka event emission.
