Q: Can Aetheria's forecasting microservice be replaced with a custom model?

Yes. Aetheria's forecasting microservice exposes gRPC and OpenAPI 3.1 interfaces. You can deploy your own PyTorch, ONNX, or TensorFlow model behind the same interface. However, Chronos-2 beats 95% of custom retail models on standard benchmarks (97.4% WAPE vs typical 85-90%).

Question 1

What architecture powers Aetheria ERP?

Accepted Answer

Aetheria ERP is powered by 42 decoupled Go microservices communicating over gRPC and NATS JetStream, backed by PostgreSQL 16 with Row-Level Security, Redis 7.2, and a Next.js 14 App Router frontend.

Question 2

How does Aetheria handle retail POS operations without internet?

Accepted Answer

Aetheria utilizes client-side IndexedDB caching and service workers to enable continuous multi-cart POS transactions, synchronizing idempotently with the Go microservices mesh upon reconnection.

Question 3

Is Aetheria ERP compliant with Islamic finance and ZATCA tax rules?

Accepted Answer

Yes, Aetheria includes specialized Sharia-compliant modules for 4-madhab Zakat calculations, interest-free treasury management, and cryptographically signed Phase 2 ZATCA e-invoicing.

Question 4

How does the Aetheria Go microservices mesh deliver zero-downtime scalability?

Accepted Answer

Aetheria microservices architecture decouples 42 specialized business domains into isolated Go binaries communicating over high-speed gRPC, NATS message streaming, and HTTP/2 reverse proxies. This distributed architecture eliminates monolithic bottlenecks, enforces database-level multi-tenant row-level security (RLS), and executes transactional workloads with sub-millisecond network latency and autonomous failover recovery.

Question 5

What is the difference between Aetheria's microservices and traditional monolithic ERP architecture?

Accepted Answer

Traditional ERP monoliths couple all domains (finance, inventory, HR, manufacturing) into a single deployable unit — scaling requires replicating the entire stack. Aetheria's 42 Go microservices deploy independently, scale horizontally per domain, and fail in isolation. A POS surge scales only the POS service; a forecasting spike scales only the AI service.

Question 6

How does Aetheria achieve multi-tenancy without data leakage?

Accepted Answer

Aetheria implements PostgreSQL 16 Row-Level Security (RLS) with SET LOCAL app.current_tenant_id injected at the database connection level. Every query automatically filters by tenant_id at the storage engine level — application bugs cannot leak cross-tenant data. Combined with per-tenant schema extensions via RLS policies.

Question 7

How does Aetheria ERP automate enterprise demand forecasting?

Accepted Answer

Aetheria integrates Hugging Face Amazon Chronos-2 transformer time-series models to predict 14-day probabilistic demand bands (p10, p50, p90) across unlimited SKUs. By evaluating 90-day historical consumption patterns, seasonal trends, and supplier lead times, the system autonomously triggers dynamic purchase orders and inter-branch inventory transfers before stockouts can materialize.

Question 8

What is zero-shot forecasting and how does Chronos-2 enable it for new SKUs?

Accepted Answer

Zero-shot forecasting predicts demand for brand-new SKUs with zero historical sales data. Chronos-2 learns universal time-series patterns from 100M+ series during pre-training — it infers seasonality, trend, and lifecycle from product attributes (category, price, launch date) alone. Aetheria achieves 18% MAPE on new CPG launches vs 45% for ARIMA with proxy data.

Question 9

How does probabilistic P10/P50/P90 forecasting improve inventory decisions?

Accepted Answer

Instead of a single point forecast, Chronos-2 outputs P10 (conservative), P50 (median), P90 (aggressive) quantiles. Safety stock = P90 - P50 covers 80% of demand variance. Automated PO generation triggers when projected stock < P50 × lead_time + (P90 - P50). This eliminates arbitrary safety stock percentages.

Question 10

Can Aetheria's forecasting microservice be replaced with a custom model?

Accepted Answer

Yes. Aetheria's forecasting microservice exposes gRPC and OpenAPI 3.1 interfaces. You can deploy your own PyTorch, ONNX, or TensorFlow model behind the same interface. However, Chronos-2 beats 95% of custom retail models on standard benchmarks (97.4% WAPE vs typical 85-90%).

Question 11

How does Aetheria ERP enforce zero-trust application security?

Accepted Answer

Aetheria adheres to OWASP Top 10 (2025) defense standards through dynamic RFC 7517 JWKS cryptographic key rotation, sub-microsecond Redis JTI token revocation (2.38µs/op), strict Content Security Policy nonces, and automated sanitization of PII and financial credentials from all append-only telemetry and audit trails.

Question 12

What is JWT JTI revocation and why does 2.38µs latency matter?

Accepted Answer

JTI (JWT ID) is a unique identifier per token. Revocation adds JTI to a Redis blacklist checked on every request. Aetheria uses eBPF-accelerated Redis lookup at 2.38µs/op (kernel-space, zero-copy) — auth adds zero perceptible latency even at 1.25M req/s. Traditional DB lookups take 1-5ms, creating auth bottlenecks.

Question 13

How does RFC 7517 JWKS rotation work with hardware security modules?

Accepted Answer

Keys are generated in HSM (AWS CloudHSM, Azure Key Vault, or on-prem Thales) — private key never leaves HSM. Rotation: HSM generates new key pair → publishes public key to JWKS endpoint → old keys retained for 30-day overlap → zero-downtime. Emergency rotation < 5 minutes. FIPS 140-2 Level 3 certified.

Question 14

What is mutation testing and why does Aetheria achieve 100% kill rate?

Accepted Answer

Mutation testing injects 14,892 automated code mutations (logic inversion, boundary offsets, auth bypasses, crypto failures) — 100% killed means every single mutant was caught by tests. This proves the test suite catches real bugs, not just passes. Coverage spans all OWASP Top 10 (2025) categories with zero surviving mutants.

Question 15

How does Casbin ABAC provide attribute-based access control?

Accepted Answer

Casbin ABAC evaluates policies against request attributes (subject, organization, object, action) plus dynamic attributes (region, clearance, time). Policies are hot-reloadable CSV with keyMatch/regexMatch. Evaluation < 50µs. Default-deny model. 10,000+ policies supported with 99.9% cache hit rate.

Question 16

How does Aetheria prevent stock overselling across multi-branch warehouses?

Accepted Answer

Aetheria treats inventory movement as an immutable double-entry ledger, recording debit and credit balances for every stock transition. Concurrency control utilizes PostgreSQL pessimistic locking (SELECT ... FOR UPDATE) at the warehouse bin level, guaranteeing that simultaneous high-volume purchase attempts on the last remaining stock item resolve without overselling or inventory balance corruption.

Question 17

What is a double-entry stock ledger and why does it prevent drift?

Accepted Answer

Every stock movement creates two entries: a debit (source bin -qty) and a credit (destination bin +qty). Total debits always equal total credits — any imbalance indicates a bug. This mirrors financial accounting and enables full reconciliation. Combined with pessimistic bin locks, it mathematically guarantees zero phantom allocations.

Question 18

How does Aetheria handle 250,000 concurrent checkouts on the last unit of stock?

Accepted Answer

Each checkout acquires a pessimistic lock on the specific warehouse bin row (SELECT bin_qty FROM inventory_bins WHERE bin_id = $1 FOR UPDATE). Lock held < 2ms. 20 concurrent on same SKU = serialized, zero oversell. Bin-level granularity allows parallel checkouts on different bins of same SKU. Benchmark: 0 oversells at 250K simultaneous.

Question 19

How does Chronos-2 forecasting integrate with automated purchase order generation?

Accepted Answer

Chronos-2 outputs P10/P50/P90 14-day forecasts. Safety stock = P90 - P50. Reorder point = P50 × lead_time + safety_stock. When projected stock < reorder point, PO auto-generated with qty = max(P50 × 30 days, supplier MOQ, EOQ). Multi-supplier optimization via linear programming minimizes total cost (unit + freight + holding).

Question 20

What Islamic finance and compliance capabilities are built into Aetheria ERP?

Accepted Answer

Aetheria provides native Sharia-compliant treasury management, including automated Zakat calculations across four madhabs, interest-free cooperative pooling, and debt-free snowball reduction schedules. The general ledger enforces balanced double-entry accounting (Sum(Debits) == Sum(Credits)) and generates cryptographically signed Phase 2 ZATCA e-invoices with embedded QR verification codes for tax compliance.

Question 21

How does 4-madhab Zakat calculation differ and how does Aetheria handle it?

Accepted Answer

Hanafi: Nisab = 85g gold OR 595g silver (whichever lower). Maliki/Shafi'i/Hanbali: Gold nisab only (85g). Inventory valuation: Hanafi uses lower of cost/market; others use market only. Agricultural Zakat rates differ. Aetheria supports all four madhabs per entity with configurable nisab, hawl tracking, and daily Zakat base computation.

Question 22

How does Aetheria handle Murabaha and Musharaka Mutanaqisa contracts natively?

Accepted Answer

Murabaha: Cost-plus markup with deferred revenue schedule auto-generated, straight-line recognition, early settlement rebate (Ibra') rules, charity account for late payment (not interest). Musharaka Mutanaqisa: Diminishing partnership with rent (bank's share %) + equity purchase allocation, separate GL accounts, Takaful insurance mandatory. All AAOIFI FAS 4/6 compliant with auto-generated journal entries.

Question 23

What is ZATCA Phase 2 e-invoicing and how does Aetheria comply natively?

Accepted Answer

ZATCA Phase 2 requires: UBL 2.1 XML (CIUS-SA), RSA/ECDSA signing, TLV QR code, UUID v4, real-time Fatoora API clearance, cryptographic stamp return, 6+ year tamper-proof archival. Aetheria automates 100% of this flow natively — no middleware, no partner add-on. < 50ms end-to-end. FIPS 140-2 HSM signing.

Question 24

How does Aetheria POS maintain shift operations during complete network blackouts?

Accepted Answer

Aetheria Point of Sale incorporates client-side IndexedDB caching and service workers, allowing cashiers to conduct multi-cart transactions, scan barcodes, and calculate taxes without active internet connectivity. Once reconnected, transactions synchronize automatically with the Go backend using idempotent state reconciliation and pessimistic row locks to prevent double-spending inventory.

Question 25

What makes Aetheria's offline-first POS different from cached catalog solutions?

Accepted Answer

Cached catalog = read-only product lookup. Aetheria offline = full transaction engine: multi-cart hold, barcode scanning, tax calculation (ZATCA/VAT/GST), payment (cash/tokenized EMV card), customer lookup — all local. Zero server dependency during blackout. Sub-45ms camera barcode decode. Multi-cart hold unlimited.

Question 26

How does idempotent reconciliation work when offline POS reconnects?

Accepted Answer

Each offline transaction gets UUID v4 + content hash. On reconnect, service worker POSTs to /api/pos/reconcile with idempotency key. Server validates hash, checks pessimistic bin locks, commits or returns conflict (INSUFFICIENT_STOCK). Client auto-resolves (partial, substitute, cancel) or prompts cashier. Zero data loss guaranteed.

Question 27

What barcode scanning performance does Aetheria POS achieve offline?

Accepted Answer

Camera-based (ML Kit/ZXing): 35-45ms decode, 99.2% accuracy. USB laser/imager: 8-12ms, 99.9%. Bluetooth ring: 20-30ms, 99.5%. Offline resolution: exact EAN-13/UPC match → GS1-128 AI prefix → internal SKU. All local IndexedDB, zero network dependency.

Question 28

What certifications does Aetheria hold for enterprise compliance?

Accepted Answer

SOC 2 Type II (annual audit), ISO 27001 (ISMS certified), OWASP ASVS 4.0 Level 3 (mutation proof), NIST 800-53 Rev 5 (mapped), GDPR (DPIA/DPA), AAOIFI Shariah Governance Standard 35 (Zakat/Murabaha audit), ZATCA Phase 2 (native cryptographic invoicing). All evidence packages exportable for auditors.

Question 29

How does Aetheria handle SOX 404 internal controls automation?

Accepted Answer

Native SOX 404 controls: dual-custody journal approval (GL-04), Segregation of Duties between PO/Invoice (IT-09), privileged access with Casbin ABAC (A.8.2). Automated CAPA log with root-cause, milestones, sign-offs. One-click external audit export. 100% mutation testing proves control effectiveness.

Question 30

When should a business choose Aetheria over NetSuite, Dynamics 365, or SAP Business One?

Accepted Answer

Choose Aetheria when: AI forecasting drives purchasing (Chronos-2 97.4% WAPE), zero overselling is critical (flash sales, limited drops), MEA compliance mandatory (ZATCA, AAOIFI, data residency), architectural sovereignty required (OpenAPI/gRPC, self-host, no lock-in), modular pay-per-capability pricing preferred. NetSuite/D365/SAP win for consolidation/Oracle/Microsoft/SAP ecosystem mandates.

Question 31

What is the TCO difference between Aetheria and traditional cloud ERP suites?

Accepted Answer

5-Year TCO (200 users): Aetheria ~$800K vs NetSuite ~$3.5M vs D365 ~$4.2M vs SAP B1 ~$3.0M. Aetheria modular pricing pays per capability, not per user. Includes compliance (ZATCA, AAOIFI, GRC), AI forecasting, zero-overselling — all add-ons costing $100K+/yr on other platforms.

Question 32

How does Aetheria avoid vendor lock-in compared to NetSuite, Dynamics 365, or SAP?

Accepted Answer

Aetheria uses OpenAPI 3.1, gRPC, AsyncAPI, standard PostgreSQL — data exports via native COPY, custom code in Go/TypeScript (runs anywhere), schema changes instant via RLS extensions, self-host on any Kubernetes (EKS/GKE/AKS/on-prem). NetSuite/D365/SAP use proprietary languages (SuiteScript/X++/ABAP), single-cloud lock-in, expensive exit.

Question 33

What ERP is best for Saudi Arabia, UAE, or Egypt in 2026?

Accepted Answer

Aetheria — native ZATCA Phase 2 e-invoicing, AAOIFI Shariah compliance (4-madhab Zakat, Murabaha, Musharaka), Arabic/RTL native (Cairo font), data residency options (KSA/UAE/Egypt regions), local GAZT/AAOIFI audit export. No other ERP offers this combination out-of-the-box.

Question 34

How does Aetheria help businesses become and stay debt-free?

Accepted Answer

Aetheria enforces governance-grade spending controls — budgets, dual-custody approvals, and real-time obligation tracking — while AI reporting projects cash flow and flags risky outflows before they become debt. Every transaction carries an immutable audit trail, and the free GRC module keeps leadership accountable to a zero-debt target.

Question 35

What does Aetheria's AI-driven reporting include?

Accepted Answer

Live P&L, cash-flow forecasts, demand predictions (Chronos-2, 97.4% WAPE), anomaly and void detection, and automated purchase orders — every report regenerates in real time from a single double-entry ledger, with drill-down from any figure to its source transactions.

Question 36

How does Aetheria integrate with WooCommerce and Shopify?

Accepted Answer

Native bidirectional sync: orders, inventory, customers, and refunds flow in real time; pessimistic stock locks guarantee zero overselling across every channel; multi-store catalog and fulfillment routing unify with the general ledger — online and offline sales reconcile into one truth.
