EQ-02 — One event, different consequences across the capital structure

Scenario — a cited cyber event fires through engine10 against a single issuer holding five instruments.

What happened — every instrument valued by its own real model, from the same event: common equity −$7.89B (DCF); the convertible reprices via Tsiveriotis-Fernandes; the call −7.68 and the put +7.95 (Black-Scholes) — opposite signs, same event. All 27 stakeholder rows land with exact long/short symmetry.

Why it matters — the instruments encode different economic exposures, so the same issuer event produces different consequences across the capital structure. No single "stock impact" number could carry this.

Boundary — single-issuer ecosystem (5 assets); frozen valuation dates mandatory (documented ~$24-on-$7.9B day-count sensitivity).
