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.

The correlator now accepts BOTH capture formats: the F10 ship-capture snapshot
and the draw-logger format (mission_draws.log / xenia_re_draws.log) via
parse_drawlog — group the ship shader's draws by vertex-buffer base, vcount =
size_words/stride_words, keep the first c0..c2 WVP. So a capital ship seen in a
normal instrumented run bakes without a dedicated F10 pass. correlate_capture
auto-detects the format. Shared normalize_wvp between both parsers.
Also add examples/ship_dump.rs (offline static-placement inspector) and record
the measured static-assembler gaps for e106 in the doc: bdy_01/bdy_02 overlap
(runtime port/starboard mirror at X=+-264), eng_02 and wep_02_01 never placed.
These confirm exact placement is runtime-only — nothing more to squeeze
statically; the capture-driven table is the only path. The draw logs present on
this box are the player fighter, so no capital-ship table can be baked offline.
7 ship_capture tests (adds draw-log parse + correlate); 77 formats-lib green.

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.

Static external-part placement (ship::assemble_ship) is only approximate — a GN_*
frame is the mount pivot, and the real offset lives in a runtime detail rig. So
capture ground truth from Canary instead.
Finding: the guest vertex buffer holds LOCAL coords (byte-identical to the .xpr),
so capital-ship parts are placed entirely in the vertex shader. The per-part
transform is in the VS float constants — c0..c2 are the WorldViewProjection rows;
normalising each by its norm (= projection x/y/z scales, sy/sx = 16:9) yields the
rigid WorldView (rows orthonormal, det +1). Expressing every part relative to a
reference part cancels the camera: rel_p = WV_ref⁻¹·WV_p, a pure ship-space rigid
transform.
- examples/correlate_capture.rs: parse xenia_ship_capture.log, decode the ship's
parts, match by vertex count, recover each part's ship-relative placement.
- docs/re/ship-placement-runtime-capture.md: full method + the capture protocol
(Canary branch capture-ship-placement, F10 hotkey) + validated e106 result.
Validated on e106 (ADAN Destroyer, Stage_S01): all 7 drawn parts matched by
vertex count; bdy_01/bdy_02 recovered as a PORT/STARBOARD pair (X = ∓264) that
static had overlapping; engines correctly aft; extent 872×670×2181. Only brg_01
(bridge) missing — culled at that camera angle, needs a bridge-facing capture.
HANDOFF: next = re-capture bridge, bake a per-ship placement table the viewer
prefers over assemble_ship, then capture the cruiser / ACROPOLIS / TCAF ships.
