## [2026-06-13] - System-Wide Handbook Sweep, English Consolidation & Crypto State Persistence (#ISSUE-014)
### Added
* **Sandbox Math Handbook**: Created `components/modules/sandbox/SandboxMathModal.tsx` detailing the Kelly Criterion, Half-Kelly safety buffers, percentage weightings (\(w_i\)), and synthetic portfolio returns (\(R_{pt}\)) in double-escaped BlockMath LaTeX.
* **Crypto Online Learning Loop**: Integrated a client-side background evaluation routine inside `components/modules/crypto/CryptoDemo.tsx` that resolves active forecasts against price histories from `/api/finance?region=crypto` and updates the Bayesian online calibration parameters.
### Modified
* **KaTeX Escaping & Close Handler Audit**: Standardized all 8 math handbook modals with Escape key listeners and glassmorphic floating top-right "X" buttons. Repaired all escaping sequences for KaTeX rendering strings across all components.
* **100% Institutional English Translation**: Swapped all remaining German UI texts, buttons (e.g. `📖 Modulerklärung` renamed to `📖 Quantitative Handbook`), table cells, and warnings to professional English across all tabs (`Smart Money`, `Events/Econometrics`, `Macro`, `Tech Silo`, `Sandbox`, `Scanner`).
* **Next.js SSR Hydration Safeguard**: Wrapped `localStorage` operations for `alphaSuccess`, `betaFailure`, and active forecasts inside a React `useEffect` hook in `CryptoDemo.tsx` to prevent hydration mismatches.
* **`QUANT_ROADMAP.md`**: Updated Section 1 and Section 4.VI detailing the Sandbox Portfolio and Kelly sizing formulations.
