512K vs 64K Line Count Discrepancy

Description

Clarification of line-count confusion in media coverage: 512,000 lines = total source-map content (comments, blank lines, type defs, test stubs, everything that leaked); 64,464 lines = core TypeScript actually serving paying customers (src/ directory). 0 test files confirmed in both counts. 64,464 is engineering reality; 512,000 is legal/IP scope.
