🔴 Rate-limit rule toggle always returns "Rule not found" error, even when the rule exists
A middleware call inserted without braces after a braceless if guard (if (rows.length === 0) at server/routers/advancedRateLimiter.ts:321-325) makes the await the only conditional statement, so the return { success: false } on the next line executes unconditionally.
Impact: Every call to toggle a rate-limit rule returns a "Rule not found" error and never actually toggles the rule.
Broken control flow from braceless if + inserted statement
The original code was:
if (rows.length === 0)
return { success: false, error: "Rule not found" };
The PR inserted a middleware call between the condition and the return:
if (rows.length === 0)
// Middleware fan-out (fail-open)
await publishadvancedRateLimiterMiddleware(...);
return { success: false, error: "Rule not found" };
In JavaScript, without braces only the first statement (await publish...) is conditional. The return is now unconditional — it always executes, preventing the code below from ever running.
The same pattern appears in:
server/routers/businessRules.ts:351-355server/routers/fraud.ts:531-535server/routers/insuranceProducts.ts:328-332server/routers/scheduledReports.ts:334-338server/routers/transactionEnrichmentService.ts:310-314server/routers/txMonitor.ts:319-323server/routers/transactionReceiptGenerator.ts:289-293server/routers/geoFencing.ts:331-339server/routers/tenantBillingOnboarding.ts:755-759
Prompt for agents
The middleware fan-out call was inserted between a braceless if-condition and its return statement in ~10 router files. In each case, the await becomes the conditional body and the return becomes unconditional, breaking the guard clause. The fix is to either: (1) wrap the if-body in braces including both the middleware call and the return, or (2) move the middleware call after the if-guard (so it only fires on the success path). Files affected: advancedRateLimiter.ts:321-325, businessRules.ts:351-355, fraud.ts:531-535, insuranceProducts.ts:328-332, scheduledReports.ts:334-338, transactionEnrichmentService.ts:310-314, txMonitor.ts:319-323, transactionReceiptGenerator.ts:289-293, geoFencing.ts:331-339, tenantBillingOnboarding.ts:755-759. In each file, search for the pattern: if (condition)\n // Middleware fan-out\n await publish...\n\n return { success: false ... }; and add braces around the intended if-body.

🔴 Business rule updates always return "Rule not found" error due to broken guard clause
A middleware call inserted without braces after a braceless if guard (if (rows.length === 0) at server/routers/businessRules.ts:351-355) makes the return unconditional, so the rule update logic never executes.
Impact: Business rule updates silently fail for every request, returning "Rule not found" even when the rule exists.
Same braceless-if pattern as BUG-0001
Lines 351-355:
if (rows.length === 0)
// Middleware fan-out (fail-open)
await publishbusinessRulesMiddleware("updateRule", ...);
return { success: false, error: "Rule not found" };
The return is unconditional because only the await is inside the if.

🔴 Fraud rule seeding always returns early, preventing default rules from ever being created
A middleware call inserted without braces after a braceless if guard (if (existing.length > 0) at server/routers/fraud.ts:531-535) makes the return unconditional, so the default fraud rules are never seeded even when the table is empty.
Impact: The seed-default-rules endpoint always reports "Rules already exist" and never populates the fraud rules table.
Same braceless-if pattern
Lines 531-535:
if (existing.length > 0)
// Middleware fan-out (fail-open)
await publishfraudMiddleware("seedDefaultRules", ...);
return { seeded: 0, message: "Rules already exist — no changes made" };
The return is unconditional.

🔴 Receipt generation always returns "Transaction not found" even for valid transactions
A middleware call inserted without braces after a braceless if guard (if (txRows.length === 0) at server/routers/transactionReceiptGenerator.ts:289-293) makes the return unconditional, so receipt generation always fails.
Impact: No receipts can be generated — every request returns a "Transaction not found" error.
Same braceless-if pattern
Lines 289-293:
if (txRows.length === 0)
// Middleware fan-out (fail-open)
await publishtransactionReceiptGeneratorMiddleware("generateReceipt", ...);
return { success: false, error: "Transaction not found" };
The return is unconditional.

🔴 Geo-fence zone creation always returns a stub response, never persisting to the database
A middleware call inserted without braces after a braceless if (!db) guard (server/routers/geoFencing.ts:331-339) makes the return with stub data unconditional, so the database insert never executes even when the DB is available.
Impact: Geo-fence zones are never actually created in the database — every call returns a fake zone ID.
Same braceless-if pattern
Lines 331-339:
if (!db)
// Middleware fan-out (fail-open)
await publishgeoFencingMiddleware("createZone", ...);
return {
id: `zone-${Date.now()}`,
name: input.name,
...
};
The return is unconditional because only the await is inside the if.

🔍 React Native dashboard screens add handleCreate/handleDelete hooks that are never rendered
All ~25 modified React Native dashboard screens (e.g. AIMonitoringDashboardScreen.tsx:39-55, AnalyticsDashboardScreen.tsx:39-55, etc.) add handleCreate and handleDelete useCallback hooks, but these functions are never referenced in the JSX return. They are dead code that increases bundle size and creates unused API endpoint references (e.g. /dashboard/create, /dashboard/${id}). Several screens use a generic /dashboard/ path that doesn't match the screen's domain (e.g. BusinessRulesDashboardScreen posts to /dashboard/create instead of /business-rules/create), suggesting these were copy-pasted from a template without customization.

🔍 Ecommerce cart addItem and catalog createProduct lost cache invalidation alongside middleware removal
Beyond the middleware event loss (reported as bugs), the refactor also removed cacheSet calls that maintained Redis cache entries. For example, ecommerceCart.ts previously called cacheSet('cart:${input.customerId}', ..., 1800) after adding items, and ecommerceCatalog.ts called cacheSet('catalog:product:${product.id}', ..., 3600) after creating products and cacheSet('catalog:inventory:${input.sku}', ..., 1800) after stock updates. The new generic publishXxxMiddleware functions don't include any cache operations. If any read paths rely on these cache keys being populated, they will now always miss cache and hit the database.

🔍 Distributed rate limiter has dual-source inconsistency between Redis and local fallback
The new rate limiter at server/middleware/securityHardening.ts:279-298 checks Redis first, then falls back to local Map. But when Redis is available, the local Map is also always updated (line 291, 297). In a multi-instance deployment, instance A might read a stale local count while instance B has already incremented the Redis count. The entry.count++ on line 296 mutates the object from either Redis or local, but the Redis write on line 298 uses the locally-incremented count — meaning two concurrent requests on different instances could both read count=5 from Redis, both increment to 6, and both write 6 back, effectively losing one count. This is a known TOCTOU issue with this read-modify-write pattern. The cacheIncr import exists but is unused — it would be the correct atomic operation for this.

🟨 Mojaloop JWS signature uses HMAC-SHA256 but claims RS256 algorithm in header
The getHeaders method in MojalloopConnector (server/middleware/middlewareConnectors.ts:690-691) computes an HMAC-SHA256 signature but embeds {"alg":"RS256"} in the protectedHeader field of the FSPIOP-Signature. This algorithm mismatch means the signature will fail verification by any spec-compliant Mojaloop hub expecting RS256 (RSA), or worse, could enable algorithm confusion attacks if the hub's verifier improperly accepts HMAC when RSA is declared.

🟨 KafkaTopic union type widened to accept any string, defeating topic validation
The KafkaTopic type in server/kafkaClient.ts:175 was extended with | string & {}, which in TypeScript makes the entire union accept any arbitrary string while preserving autocomplete. This means publishEvent can now be called with any topic name without a type error, removing the compile-time guardrail that prevented publishing to unintended or misspelled Kafka topics.
