# Reconstruction progress Generated from `config/reccmp-functions.csv`, `config/mapping.csv`, `config/implemented.csv`, and the separate exact ledgers. > `implemented.csv` records source presence only. Exact figures below > count only reproducible 100% comparisons tracked in `config/matches.csv`. - Source-present authored functions: **1,107 / 1,107 (100.00%)** - Source-present authored bytes: **459,757 / 459,757 (100.00%)** - Exact authored functions: **1,091 / 1,107 (98.55%)** - Exact authored bytes: **445,728 / 459,757 (96.95%)** - Inventory-classified library functions: **1,115** - Exact library functions: **172 / 1,115 (15.43%)** - Exact library bytes: **27,280 / 216,820 (12.58%)** The public SVG visualizes exact bytes only; source presence never fills the progress bar. Function sizes and library classification are imported analysis seeds and must be reconciled against the hash-attested target before exact acceptance.
