v1.5 · 2026-05-12
Hash Tool, Feedback, Forecast PDF, Crypto & Homepage
- Hash Tool — 4 new tabs — Comparison (two-text hash diff with match/mismatch per algorithm); File Hash (drag & drop, MD5/SHA-1/256/384/512 computed locally, no upload); Batch Mode (N inputs → hash table + CSV export); QR Code generator from any hash or text (4 error-correction levels, PNG download)
- Feedback — Reactions — 👍 🔥 💡 ❤️ 😂 buttons on every message; reaction counts stored in Workers KV; localStorage prevents double-voting; new
/api/feedback-react worker
- Feedback — Admin Reply — "↩ Reply" button in admin console writes a public reply below the original comment with gold border; stored in KV alongside the message
- Stock Forecaster — PDF Export — "Export PDF" button appears after analysis; generates A4 PDF via jsPDF with chart screenshot (canvas), metric cards, AI analysis text and page footer with disclaimer
- Crypto — Live Price — Binance WebSocket public stream updates the current price and 24h change in real time after each analysis
- Crypto — Funding Rate & Order Book Imbalance — Binance Futures and spot public APIs; funding rate signals long/short-heavy sentiment; OB imbalance shows buy/sell pressure from top-20 depth levels
- Crypto — BTC Dominance chart — 90-day dominance history rendered in the Market tab
- Crypto — Portfolio Monte Carlo — new Portfolio tab: add coins with USD allocations → N-path simulation → expected value, 95% CI, VaR, per-coin weight table

v1.4 · 2026-05-11
Hash Tool — Local DB & Crypto Forecaster — AI Analysis
- Hash local database — every hash computed (while typing or on demand) is stored in localStorage; up to 1,000,000 entries (FIFO), all algorithms except bcrypt and HMAC
- Decode: local DB as first source — lookup checks the local database before calling external APIs; results appear instantly with gold border and 🗃 badge; re-verified client-side by recomputing the hash
- Crypto Forecaster — AI Analysis — same ✦ Claude / ✦ Gemini / ✦ Groq panel as the Stock Forecaster, with a crypto-specific prompt: on-chain metrics, TVL, tokenomics, halving catalysts, regulatory risks, 1m and 3–6m outlook
- Workers: customPrompt override — all 3 AI workers (Claude, Gemini, Groq) accept a
customPrompt field in the request body, enabling domain-specific prompts without separate endpoints
- Bugfixes — AI buttons restore original labels after analysis; Gemini worker response parsed with text() + JSON.parse fallback to avoid crash on non-JSON responses
v1.3 · 2026-05-11
Stock Forecaster — Black-Scholes, Volatility Regimes & AI improvements
- Black-Scholes Options Pricer — Call/Put prices, all Greeks (Δ Γ Θ Vega ρ), interactive payoff chart at expiry vs. current, strike table (70–130% of S), heatmap Strike × Expiry with 8-metric toggle; collapsible panel before AI Analysis; risk-free rate auto-fetched from FRED (US/UK/JP) or ECB API (EU)
- Volatility Surface — simulated smile/skew from historical skewness & kurtosis; heatmap shows implied vol across strikes and expiries with term structure
- Volatility Regime Detection — rolling 21-day σ classifies each period as Low / Normal / High vol; colored overlay on the price chart with legend
- AI in user language — all three providers receive a language instruction matching the site language (9 supported); KV cache is language-keyed so different languages don't share stale entries
- AI key fallback — when the server env var is missing (503), automatically retries with the browser-stored key; Claude key field added to the ⚙ panel alongside Gemini & Groq; 401 errors show localized "go to console.X.com → create a new key" message in all 9 languages
- AI result rendering — markdown fully parsed (headings, bold, lists, inline code); section colors are semantic: 🔴 risk, 🟢 opportunity, 🟡 technical, 🔵 news, 🟣 fundamentals, 🟠 outlook; sentiment keywords colored inline
- Chart UX — zoom/pan/reset/CSV buttons centered below chart; CSV export button uses inline SVG icon; indicator chips reset on each new analysis
v1.2 · 2026-05-10
Stock Forecaster — UI, Portfolio & structural fixes
- Portfolio tab — explicit 💾 Save button with feedback; Compare and Backtesting tabs now share the same quick-fill chip picker (Stocks / Indices / ETFs + Recent searches); chips auto-refresh after each analysis
- Indicator chips — toggling SMA / Bollinger / RSI / MACD updates only the chart overlay without re-fetching data; pending state shown when analysis is stale
- Structural fixes — restored missing
mountLayout, i18nApply, STORAGE client, analyzeBtn and ticker-chip listeners, buildTickerChips, sma, rsi, switchTab, showToast and global variable declarations lost during refactor
- Service Worker v4 —
_headers file sends Cache-Control: no-cache on HTML/JS to prevent stale deploys; AI 502 errors fixed with correct anthropic-beta header and robust raw-text error parsing
- i18n — Portfolio and Backtesting fully translated; backtesting inputs validated client-side before any API call; default language forced to English on first visit

Stock Forecaster — AI Analysis, 8 data providers & infra
- AI Analysis — ✦ Claude Analysis, ✦ Gemini Analysis and ✦ Groq Analysis buttons after each forecast; real-time web search for news, fundamentals and analyst ratings; 4h KV cache (with web search) and 24h cache (knowledge-only) shared across users; browser-stored API keys bypass the Cloudflare Worker
- 8 stock data providers — Netlify-Yahoo proxy → Twelve Data → FMP → Finnhub → Alpha Vantage → Yahoo → Marketstack → Stooq; automatic fallback chain with 25s budget; session cache TTL 30min
- Monte Carlo Bootstrap — Float64Array + precomputed exp(returns) for ~15% faster simulation; range parameter now matches history slider
- Custom domain — 4suite.net live; all canonicals, OG tags and sitemap updated; robots.txt open to all crawlers
- Bugfixes — PROXIES block comment syntax error fixed;
