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.

Promote the F10 ship-capture correlator from an example into a reusable, unit-
tested library module (ship_capture): parse_capture (log -> per-draw rigid
WorldView from the c0..c2 WVP constants), correlate (match parts to draws by
vertex count, express each in the reference part's frame), and a checked-in
placement-table format (serialize_table/parse_table, embedded via
embedded_placement from data/ship_placements.txt).
build_ship_model now prefers a ship's captured placement over the static
assemble_ship when a table entry exists (empty table -> unchanged fallback).
correlate_capture example refactored onto the module + gains --emit to print a
table block. Doc updated: bake plumbing done; remaining is running real F10
captures to populate the table (needs the emulator).
5 new ship_capture tests (parse/normalize/correlate/table round-trip); 76
formats-lib tests + viewer build green.
