"""Spearfish: a Tender ("sub tub") built after the user's orthographic blueprint (reference/user_blueprint.webp), 2026-10-20:
"Create this blueprint as subtub tender 3d model in blender using MCP precisely accordingly take your time check as the
referance image". "Spearfish" is a working name after the long pointed nose; the user has not named it.

All measurements and the choices where the blueprint's views disagree are in sf_measure.py.
Axes as the Kazah and the Manta: 1 unit = 1 m, nose to -Y, port +X, Z up, origin 9 cm behind the docking clamp's axis.
No booleans. The hull is one quad grid whose columns are pinned to the canopy, side window and hatch outlines, so each
opening is a rectangle of the grid with its frame and sleeve in the same topology (sf_hull.py); fins, rails and fittings
are lofted or revolved quads with quad caps (sf_topo.py), pruned where they sink into the hull.
Runs inside the open Blender (exec through the MCP) or headless; it rebuilds only its own collections.
