+{"d":"2026-05-14","t":"FEAT","m":"Procurement: 5 neue Intelligence-Sektionen. (E) 🟢 Buy-Now Intel — Top buy_now Reorder Signals aus 211k preberechneten Signalen, filterbar nach Form Factor, Signalstärke-Balken, Preis/Stock-Trend, Gründe als Tooltip. API: GET /api/procurement/reorder-top. (A) 💰 Arbitrage — FX-Preis vs. Competitor-Preis für 59k Equivalenz-Paare mit Preisdaten auf beiden Seiten, normalisiert auf USD (EUR×1.08, GBP×1.27), sortiert nach Ersparnis-%. API: GET /api/procurement/arbitrage. (B) 🖥 Switch Compat — Suche nach Switch-Modell (Cisco, Juniper, Arista etc.), zeigt alle kompatiblen Transceiver mit Preis + Verifikationsmethode. 58k Compatibility-Rows, 429 Switches. API: GET /api/procurement/switch-compat?search=. (C) ⚠️ Supply Squeeze — Multi-Signal-Detektor: 4 parallele Quellen (Preis-Momentum 30d vs 60d, Hype-Phase, AI-Cluster-Transceiver-Nachfrage, Stock-Level-Verteilung). Severity: critical/warning/watch. API: GET /api/procurement/supply-squeeze. (D) 🪦 Dead Stock Revival — 7.297 Dead-Stock-SKUs gegen Hype-Cycle-Phasen: zeigt welche Lagerhüter in Technologieklassen liegen die gerade aufsteigen (ascending hype phases, score >30). API: GET /api/procurement/dead-stock-revival."}
 {"d":"2026-05-14","t":"FEAT","m":"Crawler Intelligence: Data Quality panel. New GET /api/scrapers/data-quality endpoint — 4 parallel queries over 200,617 transceiver_verification_evidence rows: (1) coverage breakdown (price 11,366/18,146 = 62%, image 12,333/68%, details 17,085/94%, competitor_match 399/2%, quarantined 1,193); (2) all 10 evidence types with count + avg confidence + product count + last seen; (3) robot/scraper contributions table (17 robots ranked by output); (4) daily activity last 14 days. Dashboard Crawler Intelligence tab: new 🔬 Data Quality section with coverage progress bars (color-coded ≥80% green / ≥50% amber / red), evidence type table, SVG sparkline bar chart for 14-day activity, robot contributions table with live/stale dot indicators."}
 {"d":"2026-05-14","t":"FEAT","m":"Dynamic Hype Cycle + Market Signal Engine: Hype Cycle tab is now fully data-driven. New GET /api/hype-cycle/market-signals endpoint blends 6 real data sources into a composite Market Signal Score (0–100) per technology: (1) hype_score from Norton-Bass model (30% weight), (2) hyperscaler CapEx YoY avg (Microsoft +68.8%, Alphabet +107.4%, Meta +46.8%), (3) price observation activity ratio 30d vs prior 30d, (4) AI cluster estimated transceiver demand (90d window), (5) eBay secondary market sell-through velocity, (6) internal fast-mover demand trend. Score thresholds: ≥70 green, ≥50 yellow, ≥30 orange, <30 gray. Recommendation engine: buildRecommendation(phase, signalScore, capexYoyAvg, speedGbps) maps hype phase × capex boom × speed class → Buy/Hold/Watch label with color + detail tooltip. Dashboard: Hype Cycle table shows Market Signal ● LIVE column (score + progress bar) + Recommendation column (emoji label, tooltip with reasoning). Market Context cards row above table shows Top Signal, CapEx Boom %, Fast Movers signal, eBay Velocity. New Hyperscaler CapEx panel (SEC filing data) + eBay Secondary Market panel at bottom of hype tab. Procurement: new 🛒 eBay Market sub-section with per-form-factor sell-through grid. All 6 queries run in parallel via Promise.all()."}
 {"d":"2026-05-14","t":"FEAT","m":"Procurement tab: 2 new sections with real data. (1) 📦 Internal Demand — Flexoptix internal SKU velocity from flexoptix_internal_demand table (8,585 SKUs: 70 fast-movers 53k units/12M, 239 regular, 979 slow, 7,297 dead stock). Summary cards with trend %%. Filter by velocity class. API: GET /api/procurement/internal-demand?velocity_class=&limit=&sort=. (2) 🤖 AI Clusters — live AI datacenter announcements from ai_cluster_announcements table (396 in last 30 days). Shows estimated transceiver demand per build, MW scale, company, location, source link. Filter for entries with transceiver estimates. Stats: total announcements, MW, distinct companies, total estimated transceivers. API: GET /api/procurement/ai-clusters?days=&limit=. Replaced misleading DEMO DATA banners on Signals + ABC sections with informational note pointing to Internal Demand data."}
