One scoreboard for every call QuantLogix grades: the engine against Wall Street, a valuation range before an IPO prices, a regime label against the tape. Each entry carries the date it was made and the date the market graded it. Misses are listed exactly as prominently as hits. Every entry is SHA-256 chained to the one before it, so a rewritten record is detectable by anyone. Forward-only. Never backfilled. No data vendor, bank or aggregator publishes this — because none of them keep score.
Each card links to the surface where the calls live and are graded. Aggregate disciplines publish summary statistics only and never enter the chained hit rate.
