Adaptation 8 October 2026: selective extraction of only Epicranial aponeurosis.l and Epicranial aponeurosis.r, source material Tendon, absent from the Atlas overview. Original parent transforms were evaluated, world axes (x,y,z) converted to atlas (x,z,-y) in metres, source triangles retained, reflection winding handled, normals quantized to signed 16-bit values, and geometry packed as Float32 positions / Uint32 indices. No subdivision, smoothing of geometry, shape fitting, inflation, hair, skin or donor substitution. Independent source extraction of bilateral frontalis, platysma and sternocleidomastoid reproduces all 12 existing Atlas muscle/tendon coordinate sets and bounds exactly, with identical vertex and triangle counts.

Only Startup.blend was extracted from the archive. Blender factory startup and --disable-autoexec were used. Upstream Python files and add-ons were neither extracted nor run. The two meshes have no modifiers. Their original vertex mapping, parent transforms, hashes, and checks are included. Existing small source normal/face discrepancies were preserved; the package does not certify contact accuracy, normal health, clinical completeness or anatomical validity.

Geometry and catalogue remain CC BY-SA 4.0. Audit scripts are reproduction aids. No endorsement implied. This supplement is connective tissue; it must remain in the tendon/aponeurosis display layer rather than be presented as a new muscle. Source skin, hair, eyeballs, ear structures and internal head/neck tissues remain outside this bounded supplement.
