"What Changed" — recent movements in Silicon Analysts data over a 7d/30d window, derived from the daily snapshot ledger.

"What Changed" — recent movements in Silicon Analysts data over a 7d/30d window, derived from the daily snapshot ledger. Each moved metric returns direction (up/down), magnitude (percent for value metrics, percentage-points for rate metrics), old/new values, the two snapshot dates compared, window_days_actual (real lookback — clamps to available history), and per-record provenance. Domains (the datasetId values): wafer_pricing, chip_cost, gpu_secondary, margin_benchmark, foundry_capacity, defect_density, nre_cost, packaging_benchmark, chip_archetype, electricity_price, cloud_pricing, llm_pricing, memory_spot, foundry_economics, market_prints, fab_capacity, hbm_market.
