"""Infer the footing rebar layers B1-B10 from the footing size (2026-10-19, read-only trial). The rules were read off the template pier (운곡교 P1):
bars run (footing - 200) long; the dense layers (B2/B4, B6/B8) have the two end bars, one bar 200 (X-position axis) / 175 (Y) inside, then a 125 grid;
the sparse layers (B3, B7, B1, B5) the same with a 250 grid; B9 ties sit on a 250 grid (checkerboard, half of the points); B10 hoops grow with the footing.
The result is checked against (a) the template params (P1: must reproduce) and (b) the bar counts of the pier's own rebar schedule (independent evidence).
usage: python tools/infer_footing_rebar.py <size_x> <size_y>   -> prints the layers; with --check <params.json> compares with that file's footing_rebar"""
