+## [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.
+
+### Active Bugs / Compile Status
+*   **Active Bugs**: None.
+*   **Type Checker Status**: Verified clean compilation (`npx tsc --noEmit` returns exit code 0).

+### VI. Sandbox Portfolio Cockpit & Kelly Sizing
+
+Integrates fractional betting algorithms and asset weight models inside the active Portfolio Sandbox environment.
+
+#### 1. Active Portfolio Weighting ($w_i$)
+Calculates the dynamic percentage value allocation of constituent assets:
+$$w_i = \frac{\text{Shares}_i \times P_{\text{current}, i}}{\sum_{j} \text{Shares}_j \times P_{\text{current}, j}}$$
+
+#### 2. Synthetic Portfolio Return ($R_{pt}$)
+Simulates active log returns of the combined holdings:
+$$R_{pt} = \sum_{i} w_i \times \ln\left(\frac{P_{t, i}}{P_{t-1, i}}\right)$$
+
+#### 3. Theoretical Kelly Sizing ($f^*$)
+Calculates the optimal size fraction to maximize the log growth of capital:
+$$f^* = \frac{p \cdot b - (1 - p)}{b}$$
+Where $p$ is the probability of success, and $b$ is the payout odds ratio (average win/average loss).
+
+#### 4. Half-Kelly Safety Buffer Sizing
+Applies a fractional buffer to lower estimation variance and protect against drawdowns:
+$$f_{\text{applied}} = \max\left(0, 0.5 \times f^*\right)$$
+
+---
+
 ## 5. Multi-Regime Transition Classifier
 
 The core cognitive brain of the sandbox dynamically adjusts allocation weights across our portfolio modules based on estimated macroeconomic and market states.

-          Zinskurveninversionen (z. B. wenn der <span className="text-indigo-400 font-semibold font-mono">2S10S-Yield-Spread</span> negativ ist) gelten historisch als zuverlässige Vorläufer ökonomischer Kontraktionen. Derzeit beträgt der Spread <span className="text-emerald-400 font-bold font-mono">{yieldSpread !== undefined ? (yieldSpread.current >= 0 ? '+' : '') + yieldSpread.current.toFixed(2) : '0.00'}%</span>. Gleichzeitig signalisiert der Buffett-Indikator mit <span className="text-rose-400 font-bold font-mono">{buffett !== undefined ? buffett.current.toFixed(1) : '0.0'}%</span> eine erhebliche Überbewertung des US-Aktienmarktes relativ zur Wirtschaftsleistung. Im Konsumsektor deutet die Kombination aus einer niedrigen Sparquote (<span className="text-amber-400 font-mono">{savingsRate !== undefined ? savingsRate.current.toFixed(1) : '0.0'}%</span>) und steigenden Kreditkartenausfällen (<span className="text-rose-400 font-mono">{ccDelinquency !== undefined ? ccDelinquency.current.toFixed(1) : '0.0'}%</span>) auf echten Stress hin, während der High-Yield Credit Spread (<span className="text-slate-300 font-bold font-mono">{hySpread !== undefined ? hySpread.current.toFixed(1) : '0.0'}%</span>) noch Stabilität anzeigt. 
-          Monetäre Liquidität (<span className="font-bold text-indigo-300 font-mono">Net Fed Liquidity Proxy: {netLiquidityIndicator ? netLiquidityIndicator.current.toFixed(2) : '0.00'} T$</span>) wirkt als zentraler Impulsgeber: Ein Anstieg des TGA-Volumens oder der RRP-Nutzung zieht freie Liquidität aus dem Bankensystem ab (Bremswirkung für Aktien/Krypto), während ein Abbau dieser Posten zusätzliche Liquidität freisetzt (Rückenwind für Risk Assets).
+          Yield curve inversions (e.g. when the <span className="text-indigo-400 font-semibold font-mono">2S10S Yield Spread</span> is negative) are historically reliable leading indicators of economic contractions. Currently, the spread is <span className="text-emerald-400 font-bold font-mono">{yieldSpread !== undefined ? (yieldSpread.current >= 0 ? '+' : '') + yieldSpread.current.toFixed(2) : '0.00'}%</span>. At the same time, the Buffett Indicator indicates an overvaluation of the US stock market relative to economic output. In the consumer sector, the combination of a low savings rate (<span className="text-amber-400 font-mono">{savingsRate !== undefined ? savingsRate.current.toFixed(1) : '0.0'}%</span>) and rising credit card delinquencies (<span className="text-rose-400 font-mono">{ccDelinquency !== undefined ? ccDelinquency.current.toFixed(1) : '0.0'}%</span>) suggests genuine distress, while the High-Yield credit spread (<span className="text-slate-300 font-bold font-mono">{hySpread !== undefined ? hySpread.current.toFixed(1) : '0.0'}%</span>) still indicates stability. 
+          Monetary liquidity (<span className="font-bold text-indigo-300 font-mono">Net Fed Liquidity Proxy: {netLiquidityIndicator ? netLiquidityIndicator.current.toFixed(2) : '0.00'} T$</span>) acts as a central impulse: an increase in TGA volume or RRP usage drains liquidity from the banking system (headwind for equities/crypto), while a decrease in these items releases additional liquidity (tailwind for risk assets).
