The second F10 capture (ship at _m LOD distance) closes e106 entirely: all 8 parts placed including the bridge both earlier captures missed, cross-validating the doc's 7 known translations to 0.1 units and adding brg_01 at the exact centreline (0, 153.3, -164.0). Matching hardened by what the real capture taught us: - LOD-aware: each part tries every variant vcount (base/_m/_l/_d) — a distant ship draws its LOD copies, same local frame. - Position-validated, SET-based, against the UNION of a part's variants: buffer order != decode order, and one draw's vcount equalled the _m count while its buffer held the FULL 1633-vert geometry. A coincidental vcount (foreign 51-vert mesh vs the bridge) is rejected by geometry. - Runtime mirror handled: twins share one file geometry; the engine uploads the starboard copy X-reflected. Mirror-validated draws bake diag(-1,1,1) and the viewer reverses triangle winding for det<0 so front faces stay outward. - Near-axis rotation entries snapped to exact 0/+-1 for a clean table; eng_01 keeps its genuine 30-degree nacelle rotation. data/ship_placements.txt now ships e106 (viewer renders via the captured table); embedded_e106_is_complete locks the baked data. part_pos + capture_match helper examples added. 10 ship_capture tests; 80 formats-lib tests green; viewer builds.
