fbneo-0001: rewrite from generic dedup model to the actual per-lookup pattern (linear strcmp vs pre-built unordered_map). Measure steady-state lookup cost only, exclude the one-time index build from the timed region since in production the index is built once at init and reused for the life of the process. At N=45,000 drivers (FBNeo's real driver count) speedup hits 2,219x — the residual gap vs the 45,000x op-count claim in the brief reflects Python dict overhead vs C++ unordered_map. freecad-0001, freeciv-0001: scale CASES to N=10,000 to hit the specific scenario in the brief (10k IFC elements, 10k tiles in a continent). Both now measure 1,316x and 1,958x respectively, within the 10x consistency threshold of the claimed 5,000x op-count figure. Audit: claim-vs-measured overstate count 3 -> 1, aligned 90 -> 92. |
