§01 Platform Identity

A regulated structured-capital orchestration platform.

Nexora connects banks, insurers, investors, and clients through rule-based exposure, insurance, buffer, waterfall, governance, and reporting engines — and produces auditable P&L, balance sheet, and investor return statements for every participant. Not a website, calculator, or spreadsheet. Bank-grade institutional financial infrastructure: an API-first capital modelling, execution, and financial reporting layer.

Unified Architecture — Control Center as command layer

The Control Center is not a separate module — it is the central command layer that drives every engine. All inputs flow from it. All outputs flow back to dashboards, reports, and financial statements. The architecture is a single integrated system.

This blueprint supersedes Nexora Capital Blueprint v1.0 and the Control Center Specification. Every value, formula, rate, and structural rule is derived from the validated Nexora Capital Orchestration Model v2 — 220,811 formulas, 0 errors, 10,000 Monte Carlo simulations, corrected loss waterfall, active exposure ceiling trigger, age-weighted mortality shocks, and SA market-linked premiums.

§02 Required Life Cover Engine · Live

Enter the credit. The system tells you the cover required.

The product's most fundamental calculation. Translate a credit request into the minimum insurance requirement, the eligibility-gate covenant, the premium estimate, and the full capital stack — all dynamically updated as inputs change. Every output below is derived from the validated v2 model formulas and the SA market premium table.

§2.3 · per transaction

With the exposure ceiling trigger active (Phase II — capitalisation stops at 85% × SA), maximum exposure is capped at 85% × SA regardless of tenor. The ceiling is the product's structural core — without it, exposure grows to 4–7× the advance. Required Cover is dynamic and updates monthly: Outstanding_Exposure(t) × (1 + Cohort_Buffer).

§03 SA Market Premium Engine

Premium rates, recalibrated from the SA market.

The Premium Engine looks up monthly cost per R1 000 of sum assured by age band and gender, then applies risk loadings. Rates below are the 2024–2025 South African term-life market for a healthy non-smoking professional in an office-based role. The Required Life Cover Engine pulls directly from this table.

Premiums above are indicative for a healthy, non-smoking professional in an office-based role. The Premium Engine applies the base rate from the table by age band & gender, then multiplies by selected loadings (smoker, pre-existing, occupation, hobby). Output: Monthly Premium = (SA / 1 000) × adjusted rate. Annual escalation defaults to 5% p.a. fixed from year 3, configurable per insurer.

How the engine uses these rates

1 · Lookup

By age band & gender. rate = TABLE[age_band][gender] from the matrix above. The 36-rate table is embedded in the Premium Engine and versioned alongside other assumptions.

2 · Load

Apply multiplicative loadings: adjusted = base × (1 + smoker%) × (1 + cond%) × (1 + occ%) × (1 + hobby%).

3 · Compute

Premium output: monthly = (SA / 1 000) × adjusted. Year-on-year escalation applied per the configured escalator (default 5% fixed from year 3).

§06 Senior Tranche · P&L · Balance Sheet

Senior is loss-making without the ceiling. Profitable with it.

Senior P&L recomputes from current calculator inputs (advance, coupon, funding rate, weights). With the ceiling trigger active, P(Senior loss) drops from ~83.7% to ~0.5% and the ECL provision collapses, transforming the tranche from loss-making to modestly profitable.

§08 Waterfall Engine · Full rule set

Distributions flow down. Losses climb up.

Positive cashflow allocates Senior → Mezz → Junior → Residual. Loss allocation is the strict reverse: Junior first, then Mezz, then Senior. Both directions are locked in the engine — no user override.

Structure	Positive CF allocation	Loss allocation	Risk flag
