Tier 3 matched a part to its hardpoint by trailing index, so `e105_brg`
compared "01" == "" against GN_Bridge_01 and fell through silently. The runtime
capture is what exposed it: the game draws the bridge and places it at
[0, 70, -1850] rel e105_bdy_01, and assemble_ship emitted nothing there.
With no index to match on, take the lowest-numbered frame of the category.
Diffing assemble_ship part counts across every container: 34 (stage, ship)
entries gain parts — e102 +2 (bridge and engine), e104 +1, e105 +1, Stages
02-29. ship_audit is unchanged, so nothing regressed, and the capture now agrees
to dT 0.03 / dR 0.000.
Also fixes the diff itself: correlate_frames compared static against a rotation
sampled from the first block, which can belong to another INSTANCE of the class.
Scoped to the position-agreeing cluster, e105_eng_01 goes 1.711 -> 0.000 and
both e106 nacelles to 0.000. The one remaining rotation delta (e106_wep_02_01,
0.134) is a turret whose rotation varies by 0.182 between blocks that agree on
its position — the runtime disagrees with itself more than with the assembler.
The new rotVar column makes that distinction visible.

A capture at controlled range (ship_capture_close.sh: lock a capital ship, close
on it, F10 per range band) finally draws capital-ship hulls at full detail. Two
correctness fixes were needed before the numbers meant anything:
* one F10 log is ~14 frames with no delimiter, and WV_ref^-1 . WV_p only cancels
the camera within one frame — segment_frames splits on vertex-buffer
recurrence, and correlate_frames cross-checks the blocks against each other
instead of trusting a single shot;
* aggregate by consensus, not median: a stage holds several ships of one class
sharing vertex buffers, so a block can mix two instances.
Result: f105, e105 and e106 reproduce assemble_ship to <=0.43 units in
translation and 0.000 in rotation for every part that does not move. The e106
rules generalise, and the viewer bug report now points at the viewer. Narrow
leftovers: e105_brg is missing from assemble_ship, e105_eng_01 rotation differs
by 1.711.

The runtime-capture write-up declares static ship assembly exact, but its test
covers exactly one ship (e106). Records what is suspect (engine-cluster rig,
the X-reflect twin heuristic, cross-id turrets), and that the F10 capture is
already the oracle to settle it on a second class.
